I want to manage objects in django admin, though I would like to be able only to edit objects with a specific value of some attribute. Precisely I have now in admin.py:
class UnitAdmin(admin.ModelAdmin):
list_display = ('type', 'name', 'result_file')
list_filter = ['type']
admin.site.register(Unit, UnitAdmin)
And I would like to manage only units with type='SomeSpecificType'. I saw something with overriding SimpleListFilter class, though I can't see how this applies here.
You have to override the get_queryset in de modelAdmin and filter objects that have type='SomeSpecificType.
class UnitAdmin(admin.ModelAdmin):
...
def get_queryset(self, request):
qs = super(UnitAdmin, self).get_queryset(request)
return qs.filter(type='SomeSpecificType')
You can do
class UnitAdmin(admin.ModelAdmin):
list_display = ('type', 'name', 'result_file')
list_filter = ['type']
def get_readonly_fields(self, request, obj=None):
if obj and obj.type == 'SomeSpecificType':
return []
return ["type", "name", "result_file"]
