I have a django admin filter which inherits from simplelistfilter. I'm trying to change the value of self.value() programmatically for testing purposes, but can't figure it out. Would appreciate any help.
Code here (note the TODOs): https://github.com/makinacorpus/django-safedelete/pull/175/files
The maintainer of the project has tried to help me, but I can't figure it out based on his answer: https://github.com/makinacorpus/django-safedelete/pull/175
Solved this as follows:
request = self.request_factory.get('/', {<field>: <value>})
request.user = self.request.user
changelist = self.modeladmin.get_changelist_instance(request)
queryset = changelist.get_queryset(request)
Where <field> is the field you're filtering and <value> is its desired value in the admin filter's lookups.
The queryset will contain only the filtered objects.
