ModelAdmin must define "search_fields",

[ahcm]

Hi,

upgrading from Django 2 I get:

$ ../venv/bin/python webportal/manage.py makemigrations
SystemCheckError: System check identified some issues:

ERRORS:
<class 'filer.admin.fileadmin.FileAdmin'>: (admin.E040) ModelAdmin must define "search_fields", because it's referenced by FileAdmin.autocomplete_fields.
<class 'filer.admin.folderadmin.FolderAdmin'>: (admin.E040) ModelAdmin must define "search_fields", because it's referenced by FolderAdmin.autocomplete_fields.
<class 'filer.admin.imageadmin.ImageAdmin'>: (admin.E040) ModelAdmin must define "search_fields", because it's referenced by ImageAdmin.autocomplete_fields.

These seem to define search_fields though.

Thanks !

Best
Andreas

@ahcm I cannot reproduce this. Can you give some version info?

[ahcm]

I can fix it by adding a value to search_fields to ModelAdmin in django.contrib.admin.options.
Changing search_fields = () to search_fields=('foo',).

Python 3.11.2
django-filer 3.1.3
django 5.0.6

Any other packages updated that might interfere with the admin?

Yes, filer does define them:

• django-filer/filer/admin/fileadmin.py

  Line 61 in cce13d2

  search_fields = ['name', 'original_filename', 'sha1', 'description']

• django-filer/filer/admin/folderadmin.py

  Line 64 in cce13d2

  search_fields = ['name']

• ImageAdmin does inherit it from FileAdmin

• django-filer/filer/admin/permissionadmin.py

  Line 15 in cce13d2

  search_fields = ['user__username', 'group__name', 'folder__name']

Some other code in your projects might be tempering with this.

Have you tried to open a shell (./manage.py shell) and do this?

In[1]: from filer.adminfileadmin import FileAdmin
In[2]: FileAdmin.search_fields

In case any one else has this error. My project has a custom User Model. I fixed this by adding search_fields to my customer User model admin. Essentially, this is not a problem with this project, but a field missing from my user model admin.

@rzwink Thanks for the explanation!
