Django无法为djangojs制作消息

Question

Currently I have this problem when trying to translate javascript files for Django. I have the url(r'^jsi18n/$', javascript_catalog, js_info_dict, name='javascript-catalog'), in urls.py and get that one in the template. This does not seem to be the issue to translating, when I run the django-admin.py makemessages command, it will throw some errors and I do not know why.

   $ django-admin.py makemessages -d djangojs -l nl_NL --keep-pot
    CommandError: errors happened while running msguniq
    /Users/../../src/locale/djangojs.pot:120: context separator <EOT> within string
    /Users/../../src/locale/djangojs.pot:121: context separator <EOT> within string
    msguniq: found 2 fatal errors

This is what I find in the djangojs.pot file

#: static/jsi18n/djangojs.js:38 static/jsi18n/djangojs.js:46
#: static/jsi18n/nl/djangojs.js:84 static/jsi18n/nl/djangojs.js:92
msgid " "
msgid_plural ""
msgstr[0] ""
msgstr[1] ""

When I delete these lines with empty string and run the command again, it will simply add them again after the command ran. Anyone had this issue before?

Answer 1

I fixed this by removing the \\x04 strings from the djangojs.js file, and leave an empty string there. This is not a nice fix, but it seems to work for me. I read some about this issue in this ticket https://code.djangoproject.com/ticket/17008 . It seems like it cannot escape this in the javascript file.

./static/jsi18n/djangojs.js:90: warning: Empty msgid.  It is reserved by GNU gettext:
                                         gettext("") returns the header entry with
                                         meta information, not the empty string.

This is the warning I get, but then again this seems to fix the translation problem for now.

Error Description

What happens here that it has created djangojs.js files like static/js/i18n/nl_NL/djangojs.js for all of your supported languages and in each language file it has '\\x04' strings inside these files

So when you run this command

django-admin.py makemessages -d djangojs -l nl_NL

It considers these ** djangojs.js** files as a valid source code which is used to fetch strings of these for i18n, so it consider these '\\x04' string and create a msgid for it in .po files and create this entry in .pot file

msgid "^D"
msgstr ""

^D is an <EOT> character and that's what django says in the following error

djangojs.pot:120: context separator <EOT> within string

So where ever this error comes to your command exits here without completion. After fixing it you need to re-run this command to execute it completely.

Solution

You need to do these following things

1. No need to change any of your djangojs.js files
2. don't consider djangojs.js files for i18n

So in order to fix this you need to ignore these files and don't consider these files for i18n (internationalization) by adding --ignore keyword in makemessages command like below

django-admin makemessages --locale=$bn --domain=djangojs --ignore=static/js/i18n/*

It will fix your error. :)
