Each Widget class corresponds to an HTML form widget. A Widget knows how to
|
|
render itself, given a field name and some data. Widgets don't perform
|
|
validation.

# TextInput Widget ############################################################
|
|
|
|
>>> w = TextInput()
|
|
>>> w.render('email', '')
|
|
u'<input type="text" name="email" />'
|
|
>>> w.render('email', None)
|
|
u'<input type="text" name="email" />'
|
|
>>> w.render('email', 'test@example.com')
|
|
u'<input type="text" name="email" value="test@example.com" />'
|
|
>>> w.render('email', 'some "quoted" & ampersanded value')
|
|
u'<input type="text" name="email" value="some "quoted" & ampersanded value" />'
|
|
>>> w.render('email', 'test@example.com', attrs={'class': 'fun'})
|
|
u'<input type="text" name="email" value="test@example.com" class="fun" />'
|
|
|
|
# Note that doctest in Python 2.4 (and maybe 2.5?) doesn't support non-ascii
|
|
# characters in output, so we're displaying the repr() here.
|
|
>>> w.render('email', 'ŠĐĆŽćžšđ', attrs={'class': 'fun'})
|
|
u'<input type="text" name="email" value="\u0160\u0110\u0106\u017d\u0107\u017e\u0161\u0111" class="fun" />'
|
|
|
|
You can also pass 'attrs' to the constructor:
|
|
>>> w = TextInput(attrs={'class': 'fun'})
|
|
>>> w.render('email', '')
|
|
u'<input type="text" class="fun" name="email" />'
|
|
>>> w.render('email', 'foo@example.com')
|
|
u'<input type="text" class="fun" value="foo@example.com" name="email" />'
|
|
|
|
'attrs' passed to render() get precedence over those passed to the constructor:
|
|
>>> w = TextInput(attrs={'class': 'pretty'})
|
|
>>> w.render('email', '', attrs={'class': 'special'})
|
|
u'<input type="text" class="special" name="email" />'
|
|
|
|
# PasswordInput Widget ############################################################
|
|
|
|
>>> w = PasswordInput()
|
|
>>> w.render('email', '')
|
|
u'<input type="password" name="email" />'
|
|
>>> w.render('email', None)
|
|
u'<input type="password" name="email" />'
|
|
>>> w.render('email', 'test@example.com')
|
|
u'<input type="password" name="email" value="test@example.com" />'
|
|
>>> w.render('email', 'some "quoted" & ampersanded value')
|
|
u'<input type="password" name="email" value="some "quoted" & ampersanded value" />'
|
|
>>> w.render('email', 'test@example.com', attrs={'class': 'fun'})
|
|
u'<input type="password" name="email" value="test@example.com" class="fun" />'
|
|
|
|
You can also pass 'attrs' to the constructor:
|
|
>>> w = PasswordInput(attrs={'class': 'fun'})
|
|
>>> w.render('email', '')
|
|
u'<input type="password" class="fun" name="email" />'
|
|
>>> w.render('email', 'foo@example.com')
|
|
u'<input type="password" class="fun" value="foo@example.com" name="email" />'
|
|
|
|
'attrs' passed to render() get precedence over those passed to the constructor:
|
|
>>> w = PasswordInput(attrs={'class': 'pretty'})
|
|
>>> w.render('email', '', attrs={'class': 'special'})
|
|
u'<input type="password" class="special" name="email" />'
|
|
|
|
>>> w.render('email', 'ŠĐĆŽćžšđ', attrs={'class': 'fun'})
|
|
u'<input type="password" class="fun" value="\u0160\u0110\u0106\u017d\u0107\u017e\u0161\u0111" name="email" />'
|
|
|
|
The render_value argument lets you specify whether the widget should render
|
|
its value. You may want to do this for security reasons.
|
|
>>> w = PasswordInput(render_value=True)
|
|
>>> w.render('email', 'secret')
|
|
u'<input type="password" name="email" value="secret" />'
|
|
>>> w = PasswordInput(render_value=False)
|
|
>>> w.render('email', '')
|
|
u'<input type="password" name="email" />'
|
|
>>> w.render('email', None)
|
|
u'<input type="password" name="email" />'
|
|
>>> w.render('email', 'secret')
|
|
u'<input type="password" name="email" />'
|
|
>>> w = PasswordInput(attrs={'class': 'fun'}, render_value=False)
|
|
>>> w.render('email', 'secret')
|
|
u'<input type="password" class="fun" name="email" />'
|
|
|
|
# HiddenInput Widget ############################################################
|
|
|
|
>>> w = HiddenInput()
|
|
>>> w.render('email', '')
|
|
u'<input type="hidden" name="email" />'
|
|
>>> w.render('email', None)
|
|
u'<input type="hidden" name="email" />'
|
|
>>> w.render('email', 'test@example.com')
|
|
u'<input type="hidden" name="email" value="test@example.com" />'
|
|
>>> w.render('email', 'some "quoted" & ampersanded value')
|
|
u'<input type="hidden" name="email" value="some "quoted" & ampersanded value" />'
|
|
>>> w.render('email', 'test@example.com', attrs={'class': 'fun'})
|
|
u'<input type="hidden" name="email" value="test@example.com" class="fun" />'
|
|
|
|
You can also pass 'attrs' to the constructor:
|
|
>>> w = HiddenInput(attrs={'class': 'fun'})
|
|
>>> w.render('email', '')
|
|
u'<input type="hidden" class="fun" name="email" />'
|
|
>>> w.render('email', 'foo@example.com')
|
|
u'<input type="hidden" class="fun" value="foo@example.com" name="email" />'
|
|
|
|
'attrs' passed to render() get precedence over those passed to the constructor:
|

>>> w = HiddenInput(attrs={'class': 'pretty'})
|
|
>>> w.render('email', '', attrs={'class': 'special'})
|

|
|
|
|
'attrs' passed to render() get precedence over those passed to the constructor:

|
|
|
|
# FileInput Widget ############################################################
|
|
|
|
FileInput widgets don't ever show the value, because the old value is of no use
|
|
if you are updating the form or if the provided file generated an error.
|
|
>>> w = FileInput()
|
|
>>> w.render('email', '')
|
|
u'<input type="file" name="email" />'
|
|
>>> w.render('email', None)
|
|
u'<input type="file" name="email" />'
|
|
>>> w.render('email', 'test@example.com')
|
|
u'<input type="file" name="email" />'
|
|
>>> w.render('email', 'some "quoted" & ampersanded value')
|
|
u'<input type="file" name="email" />'
|
|
>>> w.render('email', 'test@example.com', attrs={'class': 'fun'})
|
|
u'<input type="file" name="email" class="fun" />'
|
|
|
|
You can also pass 'attrs' to the constructor:
|
|
>>> w = FileInput(attrs={'class': 'fun'})
|
|
>>> w.render('email', '')
|
|
u'<input type="file" class="fun" name="email" />'
|
|
>>> w.render('email', 'foo@example.com')
|
|
u'<input type="file" class="fun" name="email" />'
|
|
|
|
>>> w.render('email', 'ŠĐĆŽćžšđ', attrs={'class': 'fun'})
|
|
u'<input type="file" class="fun" name="email" />'
|
|
|
|
# Textarea Widget #############################################################
|
|
|
|
>>> w = Textarea()
|
|
>>> w.render('msg', '')
|
|
u'<textarea rows="10" cols="40" name="msg"></textarea>'
|
|
>>> w.render('msg', None)
|
|
u'<textarea rows="10" cols="40" name="msg"></textarea>'
|
|
>>> w.render('msg', 'value')
|
|
u'<textarea rows="10" cols="40" name="msg">value</textarea>'
|
|
>>> w.render('msg', 'some "quoted" & ampersanded value')
|
|
u'<textarea rows="10" cols="40" name="msg">some "quoted" & ampersanded value</textarea>'
|
|
>>> w.render('msg', 'value', attrs={'class': 'pretty', 'rows': 20})
|
|
u'<textarea class="pretty" rows="20" cols="40" name="msg">value</textarea>'
|
|
|
|
You can also pass 'attrs' to the constructor:
|
|
>>> w = Textarea(attrs={'class': 'pretty'})
|
|
>>> w.render('msg', '')
|
|
u'<textarea rows="10" cols="40" name="msg" class="pretty"></textarea>'
|
|
>>> w.render('msg', 'example')
|
|
u'<textarea rows="10" cols="40" name="msg" class="pretty">example</textarea>'
|
|
|
|
'attrs' passed to render() get precedence over those passed to the constructor:
|
|
>>> w = Textarea(attrs={'class': 'pretty'})
|
|
>>> w.render('msg', '', attrs={'class': 'special'})
|
|
u'<textarea rows="10" cols="40" name="msg" class="special"></textarea>'
|
|
|
|
>>> w.render('msg', 'ŠĐĆŽćžšđ', attrs={'class': 'fun'})
|
|
u'<textarea rows="10" cols="40" name="msg" class="fun">\u0160\u0110\u0106\u017d\u0107\u017e\u0161\u0111</textarea>'
|
|
|
|
# CheckboxInput Widget ########################################################
|
|
|
|
>>> w = CheckboxInput()
|
|
>>> w.render('is_cool', '')
|
|
u'<input type="checkbox" name="is_cool" />'
|
|
>>> w.render('is_cool', None)
|
|
u'<input type="checkbox" name="is_cool" />'
|
|
>>> w.render('is_cool', False)
|
|
u'<input type="checkbox" name="is_cool" />'
|
|
>>> w.render('is_cool', True)
|
|
u'<input checked="checked" type="checkbox" name="is_cool" />'
|
|
|
|
Using any value that's not in ('', None, False, True) will check the checkbox
|
|
and set the 'value' attribute.
|
|
>>> w.render('is_cool', 'foo')
|
|
u'<input checked="checked" type="checkbox" name="is_cool" value="foo" />'
|
|
|
|
>>> w.render('is_cool', False, attrs={'class': 'pretty'})
|
|
u'<input type="checkbox" name="is_cool" class="pretty" />'
|
|
|
|
You can also pass 'attrs' to the constructor:
|
|
>>> w = CheckboxInput(attrs={'class': 'pretty'})
|
|
>>> w.render('is_cool', '')
|
|
u'<input type="checkbox" class="pretty" name="is_cool" />'
|
|
|
|
'attrs' passed to render() get precedence over those passed to the constructor:
|
|
>>> w = CheckboxInput(attrs={'class': 'pretty'})
|
|
>>> w.render('is_cool', '', attrs={'class': 'special'})
|
|
u'<input type="checkbox" class="special" name="is_cool" />'
|
|
|
|
You can pass 'check_test' to the constructor. This is a callable that takes the
|
|
value and returns True if the box should be checked.
|
|
>>> w = CheckboxInput(check_test=lambda value: value.startswith('hello'))
|
|
>>> w.render('greeting', '')
|
|
u'<input type="checkbox" name="greeting" />'
|
|
>>> w.render('greeting', 'hello')
|
|
u'<input checked="checked" type="checkbox" name="greeting" value="hello" />'
|
|
>>> w.render('greeting', 'hello there')
|
|
u'<input checked="checked" type="checkbox" name="greeting" value="hello there" />'
|
|
>>> w.render('greeting', 'hello & goodbye')
|
|
u'<input checked="checked" type="checkbox" name="greeting" value="hello & goodbye" />'
|
|
|
|
A subtlety: If the 'check_test' argument cannot handle a value and raises any
|
|
exception during its __call__, then the exception will be swallowed and the box
|
|
will not be checked. In this example, the 'check_test' assumes the value has a
|
|
startswith() method, which fails for the values True, False and None.
|
|
>>> w.render('greeting', True)
|
|
u'<input type="checkbox" name="greeting" />'
|
|
>>> w.render('greeting', False)
|
|
u'<input type="checkbox" name="greeting" />'
|
|
>>> w.render('greeting', None)
|
|
u'<input type="checkbox" name="greeting" />'
|
|
|
|
The CheckboxInput widget will return False if the key is not found in the data
|
|
dictionary (because HTML form submission doesn't send any result for unchecked
|
|
checkboxes).
|
|
>>> w.value_from_datadict({}, {}, 'testing')
|
|
False
|
|
|
|
# Select Widget ###############################################################
|
|
|
|
>>> w = Select()
|
|
>>> print w.render('beatle', 'J', choices=(('J', 'John'), ('P', 'Paul'), ('G', 'George'), ('R', 'Ringo')))
|
|
<select name="beatle">
|
|
<option value="J" selected="selected">John</option>
|
|
<option value="P">Paul</option>
|
|
<option value="G">George</option>
|
|
<option value="R">Ringo</option>
|
|
</select>
|
|
|
|
If the value is None, none of the options are selected:
|
|
>>> print w.render('beatle', None, choices=(('J', 'John'), ('P', 'Paul'), ('G', 'George'), ('R', 'Ringo')))
|
|
<select name="beatle">
|
|
<option value="J">John</option>
|
|
<option value="P">Paul</option>
|
|
<option value="G">George</option>
|
|
<option value="R">Ringo</option>
|
|
</select>
|
|
|
|
If the value corresponds to a label (but not to an option value), none of the options are selected:
|
|
>>> print w.render('beatle', 'John', choices=(('J', 'John'), ('P', 'Paul'), ('G', 'George'), ('R', 'Ringo')))
|
|
<select name="beatle">
|
|
<option value="J">John</option>
|
|
<option value="P">Paul</option>
|
|
<option value="G">George</option>
|
|
<option value="R">Ringo</option>
|
|
</select>
|
|
|
|
The value is compared to its str():
|
|
>>> print w.render('num', 2, choices=[('1', '1'), ('2', '2'), ('3', '3')])
|
|
<select name="num">
|
|
<option value="1">1</option>
|
|
<option value="2" selected="selected">2</option>
|
|
<option value="3">3</option>
|
|
</select>
|
|
>>> print w.render('num', '2', choices=[(1, 1), (2, 2), (3, 3)])
|
|
<select name="num">
|
|
<option value="1">1</option>
|
|
<option value="2" selected="selected">2</option>
|
|
<option value="3">3</option>
|
|
</select>
|
|
>>> print w.render('num', 2, choices=[(1, 1), (2, 2), (3, 3)])
|
|
<select name="num">
|
|
<option value="1">1</option>
|
|
<option value="2" selected="selected">2</option>
|
|
<option value="3">3</option>
|
|
</select>
|
|
|
|
The 'choices' argument can be any iterable:
|
|
>>> from itertools import chain
|
|
>>> def get_choices():
|
|
... for i in range(5):
|
|
... yield (i, i)
|
|
>>> print w.render('num', 2, choices=get_choices())
|
|
<select name="num">
|
|
<option value="0">0</option>
|
|
<option value="1">1</option>
|
|
<option value="2" selected="selected">2</option>
|
|
<option value="3">3</option>
|
|
<option value="4">4</option>
|
|
</select>
|
|
>>> things = ({'id': 1, 'name': 'And Boom'}, {'id': 2, 'name': 'One More Thing!'})
|
|
>>> class SomeForm(Form):
|
|
... somechoice = ChoiceField(choices=chain((('', '-'*9),), [(thing['id'], thing['name']) for thing in things]))
|
|
>>> f = SomeForm()
|
|
>>> f.as_table()
|
|
u'<tr><th><label for="id_somechoice">Somechoice:</label></th><td><select name="somechoice" id="id_somechoice">\n<option value="" selected="selected">---------</option>\n<option value="1">And Boom</option>\n<option value="2">One More Thing!</option>\n</select></td></tr>'
|
|
>>> f.as_table()
|
|
u'<tr><th><label for="id_somechoice">Somechoice:</label></th><td><select name="somechoice" id="id_somechoice">\n<option value="" selected="selected">---------</option>\n<option value="1">And Boom</option>\n<option value="2">One More Thing!</option>\n</select></td></tr>'
|
|
>>> f = SomeForm({'somechoice': 2})
|
|
>>> f.as_table()
|
|
u'<tr><th><label for="id_somechoice">Somechoice:</label></th><td><select name="somechoice" id="id_somechoice">\n<option value="">---------</option>\n<option value="1">And Boom</option>\n<option value="2" selected="selected">One More Thing!</option>\n</select></td></tr>'
|
|
|
|
You can also pass 'choices' to the constructor:
|
|
>>> w = Select(choices=[(1, 1), (2, 2), (3, 3)])
|
|
>>> print w.render('num', 2)
|
|
<select name="num">
|
|
<option value="1">1</option>
|
|
<option value="2" selected="selected">2</option>
|
|
<option value="3">3</option>
|
|
</select>
|
|
|
|
If 'choices' is passed to both the constructor and render(), then they'll both be in the output:
|
|
>>> print w.render('num', 2, choices=[(4, 4), (5, 5)])
|
|
<select name="num">
|
|
<option value="1">1</option>
|
|
<option value="2" selected="selected">2</option>
|
|
<option value="3">3</option>
|
|
<option value="4">4</option>
|
|
<option value="5">5</option>
|
|
</select>
|
|
|
|
>>> w.render('email', 'ŠĐĆŽćžšđ', choices=[('ŠĐĆŽćžšđ', 'ŠĐabcĆŽćžšđ'), ('ćžšđ', 'abcćžšđ')])

RadioSelect uses a RadioFieldRenderer to render the individual radio inputs.
|
|
You can manipulate that object directly to customize the way the RadioSelect
|
|
is rendered.
|
|
>>> w = RadioSelect()
|
|
>>> r = w.get_renderer('beatle', 'J', choices=(('J', 'John'), ('P', 'Paul'), ('G', 'George'), ('R', 'Ringo')))
|
|
>>> for inp in r:
|
|
... print inp
|
|
<label><input checked="checked" type="radio" name="beatle" value="J" /> John</label>
|
|
<label><input type="radio" name="beatle" value="P" /> Paul</label>
|
|
<label><input type="radio" name="beatle" value="G" /> George</label>
|
|
<label><input type="radio" name="beatle" value="R" /> Ringo</label>
|
|
>>> for inp in r:
|
|
... print '%s<br />' % inp
|
|
<label><input checked="checked" type="radio" name="beatle" value="J" /> John</label><br />
|
|
<label><input type="radio" name="beatle" value="P" /> Paul</label><br />
|
|
<label><input type="radio" name="beatle" value="G" /> George</label><br />
|
|
<label><input type="radio" name="beatle" value="R" /> Ringo</label><br />
|
|
>>> for inp in r:
|
|
... print '<p>%s %s</p>' % (inp.tag(), inp.choice_label)
|
|
<p><input checked="checked" type="radio" name="beatle" value="J" /> John</p>
|
|
<p><input type="radio" name="beatle" value="P" /> Paul</p>
|
|
<p><input type="radio" name="beatle" value="G" /> George</p>
|
|
<p><input type="radio" name="beatle" value="R" /> Ringo</p>
|
|
>>> for inp in r:
|
|
... print '%s %s %s %s %s' % (inp.name, inp.value, inp.choice_value, inp.choice_label, inp.is_checked())
|
|
beatle J J John True
|
|
beatle J P Paul False
|
|
beatle J G George False
|
|
beatle J R Ringo False
|
|
|
|
You can create your own custom renderers for RadioSelect to use.
|
|
>>> class MyRenderer(RadioFieldRenderer):
|
|
... def render(self):
|
|
... return u'<br />\n'.join([unicode(choice) for choice in self])
|
|
>>> w = RadioSelect(renderer=MyRenderer)
|
|
>>> print w.render('beatle', 'G', choices=(('J', 'John'), ('P', 'Paul'), ('G', 'George'), ('R', 'Ringo')))
|
|
<label><input type="radio" name="beatle" value="J" /> John</label><br />
|
|
<label><input type="radio" name="beatle" value="P" /> Paul</label><br />
|
|
<label><input checked="checked" type="radio" name="beatle" value="G" /> George</label><br />
|
|
<label><input type="radio" name="beatle" value="R" /> Ringo</label>
|
|
|
|
A RadioFieldRenderer object also allows index access to individual RadioInput
|
|
objects.
|
|
>>> w = RadioSelect()
|
|
>>> r = w.get_renderer('beatle', 'J', choices=(('J', 'John'), ('P', 'Paul'), ('G', 'George'), ('R', 'Ringo')))
|
|
>>> print r[1]
|
|
<label><input type="radio" name="beatle" value="P" /> Paul</label>
|
|
>>> print r[0]
|
|
<label><input checked="checked" type="radio" name="beatle" value="J" /> John</label>
|
|
>>> r[0].is_checked()
|
|
True
|
|
>>> r[1].is_checked()
|
|
False
|
|
>>> r[1].name, r[1].value, r[1].choice_value, r[1].choice_label
|
|
('beatle', u'J', u'P', u'Paul')

<li><label><input type="checkbox" name="beatles" value="G" /> George</label></li>
|
|
<li><label><input type="checkbox" name="beatles" value="R" /> Ringo</label></li>
|
|
</ul>
|
|
>>> print w.render('beatles', ['J', 'P', 'R'], choices=(('J', 'John'), ('P', 'Paul'), ('G', 'George'), ('R', 'Ringo')))
|
|
<ul>
|
|
<li><label><input checked="checked" type="checkbox" name="beatles" value="J" /> John</label></li>
|
|
<li><label><input checked="checked" type="checkbox" name="beatles" value="P" /> Paul</label></li>
|

<li><label><input type="checkbox" name="beatles" value="G" /> George</label></li>
|
|
<li><label><input checked="checked" type="checkbox" name="beatles" value="R" /> Ringo</label></li>
|
|
</ul>
|
|
|
|
If the value is None, none of the options are selected:
|
|
>>> print w.render('beatles', None, choices=(('J', 'John'), ('P', 'Paul'), ('G', 'George'), ('R', 'Ringo')))
|
|
<ul>
|
|
<li><label><input type="checkbox" name="beatles" value="J" /> John</label></li>
|
|
<li><label><input type="checkbox" name="beatles" value="P" /> Paul</label></li>
|
|
<li><label><input type="checkbox" name="beatles" value="G" /> George</label></li>
|
|
<li><label><input type="checkbox" name="beatles" value="R" /> Ringo</label></li>
|
|
</ul>
|
|
|
|
If the value corresponds to a label (but not to an option value), none of the options are selected:
|
|
>>> print w.render('beatles', ['John'], choices=(('J', 'John'), ('P', 'Paul'), ('G', 'George'), ('R', 'Ringo')))
|
|
<ul>
|
|
<li><label><input type="checkbox" name="beatles" value="J" /> John</label></li>
|
|
<li><label><input type="checkbox" name="beatles" value="P" /> Paul</label></li>
|
|
<li><label><input type="checkbox" name="beatles" value="G" /> George</label></li>
|
|
<li><label><input type="checkbox" name="beatles" value="R" /> Ringo</label></li>
|
|
</ul>
|
|
|
|
If multiple values are given, but some of them are not valid, the valid ones are selected:
|
|
>>> print w.render('beatles', ['J', 'G', 'foo'], choices=(('J', 'John'), ('P', 'Paul'), ('G', 'George'), ('R', 'Ringo')))
|
|
<ul>
|
|
<li><label><input checked="checked" type="checkbox" name="beatles" value="J" /> John</label></li>
|
|
<li><label><input type="checkbox" name="beatles" value="P" /> Paul</label></li>
|
|
<li><label><input checked="checked" type="checkbox" name="beatles" value="G" /> George</label></li>
|
|
<li><label><input type="checkbox" name="beatles" value="R" /> Ringo</label></li>
|
|
</ul>
|
|
|
|
The value is compared to its str():
|
|
>>> print w.render('nums', [2], choices=[('1', '1'), ('2', '2'), ('3', '3')])
|
|
<ul>
|
|
<li><label><input type="checkbox" name="nums" value="1" /> 1</label></li>
|
|
<li><label><input checked="checked" type="checkbox" name="nums" value="2" /> 2</label></li>
|
|
<li><label><input type="checkbox" name="nums" value="3" /> 3</label></li>
|
|
</ul>
|
|
>>> print w.render('nums', ['2'], choices=[(1, 1), (2, 2), (3, 3)])
|
|
<ul>
|
|
<li><label><input type="checkbox" name="nums" value="1" /> 1</label></li>
|
|
<li><label><input checked="checked" type="checkbox" name="nums" value="2" /> 2</label></li>
|
|
<li><label><input type="checkbox" name="nums" value="3" /> 3</label></li>
|
|
</ul>
|
|
>>> print w.render('nums', [2], choices=[(1, 1), (2, 2), (3, 3)])
|
|
<ul>
|
|
<li><label><input type="checkbox" name="nums" value="1" /> 1</label></li>
|
|
<li><label><input checked="checked" type="checkbox" name="nums" value="2" /> 2</label></li>
|
|
<li><label><input type="checkbox" name="nums" value="3" /> 3</label></li>
|
|
</ul>
|
|
|
|
The 'choices' argument can be any iterable:
|
|
>>> def get_choices():
|
|
... for i in range(5):
|
|
... yield (i, i)
|
|
>>> print w.render('nums', [2], choices=get_choices())
|
|
<ul>
|
|
<li><label><input type="checkbox" name="nums" value="0" /> 0</label></li>
|
|
<li><label><input type="checkbox" name="nums" value="1" /> 1</label></li>
|
|
<li><label><input checked="checked" type="checkbox" name="nums" value="2" /> 2</label></li>
|
|
<li><label><input type="checkbox" name="nums" value="3" /> 3</label></li>
|
|
<li><label><input type="checkbox" name="nums" value="4" /> 4</label></li>
|
|
</ul>
|
|
|
|
You can also pass 'choices' to the constructor:
|
|
>>> w = CheckboxSelectMultiple(choices=[(1, 1), (2, 2), (3, 3)])
|
|
>>> print w.render('nums', [2])
|
|
<ul>
|
|
<li><label><input type="checkbox" name="nums" value="1" /> 1</label></li>
|
|
<li><label><input checked="checked" type="checkbox" name="nums" value="2" /> 2</label></li>
|
|
<li><label><input type="checkbox" name="nums" value="3" /> 3</label></li>
|
|
</ul>
|
|
|
|
If 'choices' is passed to both the constructor and render(), then they'll both be in the output:
|
|
>>> print w.render('nums', [2], choices=[(4, 4), (5, 5)])
|
|
<ul>
|
|
<li><label><input type="checkbox" name="nums" value="1" /> 1</label></li>
|
|
<li><label><input checked="checked" type="checkbox" name="nums" value="2" /> 2</label></li>
|
|
<li><label><input type="checkbox" name="nums" value="3" /> 3</label></li>
|
|
<li><label><input type="checkbox" name="nums" value="4" /> 4</label></li>
|
|
<li><label><input type="checkbox" name="nums" value="5" /> 5</label></li>
|
|
</ul>
|
|
|
|
>>> w.render('nums', ['ŠĐĆŽćžšđ'], choices=[('ŠĐĆŽćžšđ', 'ŠĐabcĆŽćžšđ'), ('ćžšđ', 'abcćžšđ')])
|
