Question

I’ve tried various methods to achieve this.

I decided against overriding formfield_for_dbfield as it doesn’t get a copy of the request object and I was hoping to avoid the thread_locals hack.

I settled on overriding get_form in my ModelAdmin class and tried the following:

class PageOptions(admin.ModelAdmin):     def get_form(self, request, obj=None, **kwargs):         if request.user.is_superuser:             self.fieldsets = ((None, {'fields': ('title','name',),}),)         else:             self.fieldsets = ((None, {'fields': ('title',),}),)         return super(PageOptions,self).get_form(request, obj=None, **kwargs) 

When I print fieldsets or declared_fieldsets from within get_form I get None (or whatever I set as an initial value in PageOptions).

Why doesn’t this work and is there a better way to do this?

I have no idea why printing the property doesn’t give you want you just assigned (I guess may be that depends on where you print, exactly), but try overriding get_fieldsets instead. The base implementation looks like this:

def get_fieldsets(self, request, obj=None):     if self.declared_fieldsets:         return self.declared_fieldsets     form = self.get_formset(request).form     return [(None, {'fields': form.base_fields.keys()})] 

I.e. you should be able to just return your tuples.

EDIT by andybak. 4 years on and I found my own question again when trying to do something similar on another project. This time I went with this approach although modified slightly to avoid having to repeat fieldsets definition:

def get_fieldsets(self, request, obj=None):     # Add 'item_type' on add forms and remove it on changeforms.     fieldsets = super(ItemAdmin, self).get_fieldsets(request, obj)     if not obj: # this is an add form         if 'item_type' not in fieldsets[0][1]['fields']:             fieldsets[0][1]['fields'] += ('item_type',)     else: # this is a change form         fieldsets[0][1]['fields'] = tuple(x for x in fieldsets[0][1]['fields'] if x!='item_type')     return fieldsets
