||||
The ``javascript_catalog`` view
|
||||
-------------------------------
|
||||
|
||||
.. function:: javascript_catalog(request, domain='djangojs', packages=None)
|
||||
|
||||
.. deprecated:: 1.10
|
||||
|
||||
``javascript_catalog()`` is deprecated in favor of
|
||||
:class:`JavaScriptCatalog` and will be removed in Django 2.0.
|
||||
|
||||
The main solution to these problems is the
|
||||
:meth:`django.views.i18n.javascript_catalog` view, which sends out a JavaScript
|
||||
code library with functions that mimic the ``gettext`` interface, plus an array
|
||||
of translation strings. Those translation strings are taken from applications or
|
||||
Django core, according to what you specify in either the ``info_dict`` or the
|
||||
URL. Paths listed in :setting:`LOCALE_PATHS` are also included.
|
||||
|
||||
You hook it up like this::
|
||||
|
||||
from django.views.i18n import javascript_catalog
|
||||
|
||||
js_info_dict = {
|
||||
'packages': ('your.app.package',),
|
||||
}
|
||||
|
||||
urlpatterns = [
|
||||
url(r'^jsi18n/$', javascript_catalog, js_info_dict, name='javascript-catalog'),
|
||||
]
|
||||
|
||||
Each string in ``packages`` should be in Python dotted-package syntax (the
|
||||
same format as the strings in :setting:`INSTALLED_APPS`) and should refer to a
|
||||
package that contains a ``locale`` directory. If you specify multiple packages,
|
||||
all those catalogs are merged into one catalog. This is useful if you have
|
||||
JavaScript that uses strings from different applications.
|
||||
|
||||
The precedence of translations is such that the packages appearing later in the
|
||||
``packages`` argument have higher precedence than the ones appearing at the
|
||||
beginning, this is important in the case of clashing translations for the same
|
||||
literal.
|
||||
|
||||
By default, the view uses the ``djangojs`` gettext domain. This can be
|
||||
changed by altering the ``domain`` argument.
|
||||
|
||||
You can make the view dynamic by putting the packages into the URL pattern::
|
||||
|
||||
urlpatterns = [
|
||||
url(r'^jsi18n/(?P<packages>\S+?)/$', javascript_catalog, name='javascript-catalog'),
|
||||
]
|
||||
|
||||
With this, you specify the packages as a list of package names delimited by '+'
|
||||
signs in the URL. This is especially useful if your pages use code from
|
||||
different apps and this changes often and you don't want to pull in one big
|
||||
catalog file. As a security measure, these values can only be either
|
||||
``django.conf`` or any package from the :setting:`INSTALLED_APPS` setting.
|
||||
|
||||
You can also split the catalogs in multiple URLs and load them as you need in
|
||||
your sites::
|
||||
|
||||
js_info_dict_app = {
|
||||
'packages': ('your.app.package',),
|
||||
}
|
||||
|
||||
js_info_dict_other_app = {
|
||||
'packages': ('your.other.app.package',),
|
||||
}
|
||||
|
||||
urlpatterns = [
|
||||
url(r'^jsi18n/app/$', javascript_catalog, js_info_dict_app),
|
||||
url(r'^jsi18n/other_app/$', javascript_catalog, js_info_dict_other_app),
|
||||
]
|
||||
|
||||
If you use more than one ``javascript_catalog`` on a site and some of them
|
||||
define the same strings, the strings in the catalog that was loaded last take
|
||||
precedence.
|
||||
|
||||
The JavaScript translations found in the paths listed in the
|
||||
:setting:`LOCALE_PATHS` setting are also always included. To keep consistency
|
||||
with the translations lookup order algorithm used for Python and templates, the
|
||||
directories listed in :setting:`LOCALE_PATHS` have the highest precedence with
|
||||
the ones appearing first having higher precedence than the ones appearing
|
||||
later.

``json_catalog()`` is deprecated in favor of :class:`JSONCatalog` and will

be removed in Django 2.0.
|
||||
|
||||
In order to use another client-side library to handle translations, you may
|
||||
want to take advantage of the ``json_catalog()`` view. It's similar to
|
||||
:meth:`~django.views.i18n.javascript_catalog` but returns a JSON response.
|
||||
|
||||
The JSON object contains i18n formatting settings (those available for
|
||||
`get_format`_), a plural rule (as a ``plural`` part of a GNU gettext
|
||||
``Plural-Forms`` expression), and translation strings. The translation strings
|
||||
are taken from applications or Django's own translations, according to what is
|
||||
specified either via ``urlpatterns`` arguments or as request parameters. Paths
|
||||
listed in :setting:`LOCALE_PATHS` are also included.
|
||||
|
||||
The view is hooked up to your application and configured in the same fashion as
|
||||
:meth:`~django.views.i18n.javascript_catalog` (namely, the ``domain`` and
|
||||
``packages`` arguments behave identically)::
|
||||
|
||||
from django.views.i18n import json_catalog
|
||||
|
||||
js_info_dict = {
|
||||
'packages': ('your.app.package',),

}
|
||||

||||
urlpatterns = [
|
||||
url(r'^jsoni18n/$', json_catalog, js_info_dict),
|
||||
]
|
||||
|
||||
The response format is as follows:
|
||||
|
||||
.. code-block:: text
|
||||
|
||||
{
|
||||
"catalog": {
|
||||
# Translations catalog
