Adrian Amaglio nobody "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)) Using cached https://files.pythonhosted.org/packages/36/50/078a42b4e9bedb94efd3e0278c0eb71650ed9672cdc91bd5542953bec17f/ Django-2.1.5-py3-none-any.whl Collecting pytz (from django->-r requirements.txt (line 1)) Using cached https://files.pythonhosted.org/packages/61/28/1d3920e4d1d50b19bc5d24398a7cd85cc7b9a75a490570d5a30c57622d34/ pytz-2018.9-py2.py3-none-any.whl Installing collected packages: pytz, django 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 ?
