I have a django app that works well, in development and production.
I tried to translate the admin view so I created Meta subclasses, added
verbose_name on my fields with the 'django.utils.translation.gettext_lazy'
function.
Here is what I did :
Creation of virtualenv in my freshly pulled code
{{{
$ virtualenv djangovenv
Using base prefix '/usr'
New python executable in /home/py/git/court-metrage/djangovenv/bin/python
Installing setuptools, pip, wheel...done.
}}}
Sourcing and installing dependencies
{{{
$ source djangovenv/bin/activate
(djangovenv) $ pip install -r requirements.txt
Collecting django (from -r requirements.txt (line 1))

pytz-2018.9-py2.py3-none-any.whl

Successfully installed django-2.1.5 pytz-2018.9
}}}
Generating translation files
{{{
(djangovenv) $ ./manage.py makemessages -l fr_FR
processing locale fr_FR
}}}
Here, I got my .po files with all the string from my model and I can run
the server and everything is fine (seems logic as I did not change django
files)
{{{
(djangovenv) $ ./manage.py runserver
Performing system checks...
System check identified no issues (0 silenced).
January 25, 2019 - 16:48:51
Django version 2.1.5, using settings 'courtmetrage.settings'
Starting development server at http://127.0.0.1:8000/
Quit the server with CONTROL-C.
}}}
I generate the translation
{{{
(djangovenv) $ ./manage.py compilemessages
…
processing file django.po in /myrepo/djangovenv/lib/python3.7/site-
packages/django/contrib/auth/locale/ne/LC_MESSAGES
…
}}}
The output is VERY verbose (1127 lines). I guess django generated admin
lang for every locale ever. No errors so far…
But then, when I try to run manage.py with any parameters, I got an error
:
{{{
ValueError: invalid token in plural form: EXPRESSION
}}}
The manage.py script is still running, maybe wating for file change.
The problem remains until I delete the virtualenv dir and recreate it…
I don’t know what is EXPRESSION, I tried to remove the line as some people
advised on stackoverflow but the error remains…
Am I missing something ? How those basics steps can break my project ?
