Access model object in admin.StackedInline inline

Question

I am trying to use an inline in UserAdmin in admin.py I am looking for a way to modify the fields of that inline based on the object.

ProfileInline

class ProfileInline(admin.StackedInline):
    model = UserProfile
    filter_horizontal = ('user_markets',)
    fk_name = 'user'
    max_num = 1
    can_delete = False
    fields = ('email_role', )
    verbose_name_plural = 'Profile'

UserAdmin

class UserAdmin(UserAdmin):
    list_display = ('username', 'email', 'first_name', 'last_name', 'is_staff', roles, login)
    list_filter = ('groups',)
    inlines = (ProfileInline,)

Here I need to modify ProfileInline.fields = ('department','email_role') if the user belongs to the Sales Group, else whatever.

I need a way to access the user Object and update the fields.

Answer 1

class ProfileInline(admin.StackedInline):
    model = UserProfile
    filter_horizontal = ('user_markets',)
    fk_name = 'user'
    max_num = 1
    can_delete = False
    fields = ('email_role', )
    verbose_name_plural = 'Profile'

    def get_fieldsets(self, request, obj=None):
        fieldsets = super(ProfileInline, self).get_fieldsets(request, obj)

        # fieldsets[0][1]['fields'].remove('email_role')
        fieldsets[0][1]['fields'] = ('department', 'email_role')

        return fieldsets

get_fieldsets method is your solution. You have request object so request.user also.
