I\'m trying to make all fields readonly without listing them explicitly.
Something like:
class CustomAdmin(admin.ModelAdmin):
def get_readonly_fi
Careful, self.model._meta.fields are not necessarily the same fields that CustomAdmin has!
"All fields of the Admin" would look more like this:
from django.contrib import admin
from django.contrib.admin.utils import flatten_fieldsets
class CustomAdmin(admin.ModelAdmin):
def get_readonly_fields(self, request, obj=None):
if request.user.is_superuser:
return self.readonly_fields
if self.declared_fieldsets:
return flatten_fieldsets(self.declared_fieldsets)
else:
return list(set(
[field.name for field in self.opts.local_fields] +
[field.name for field in self.opts.local_many_to_many]
))
Ok, now there's this:
class CustomAdmin(admin.ModelAdmin):
def get_readonly_fields(self, request, obj=None):
# ...
return [f.name for f in self.model._meta.fields]
Still looking for a less ugly way.
You could iterate through the model meta fields:
def get_readonly_fields(self, request, obj=None):
if obj:
self.readonly_fields = [field.name for field in obj.__class__._meta.fields]
return self.readonly_fields
My requirement was similar . I needed only one field to be shown as read-only . And this worked fine:
class ChoiceInline(admin.TabularInline):
model = Choice
extra = 1
fields = ['choice_text', 'votes']
readonly_fields = ['votes']
class QuestionAdmin(admin.ModelAdmin):
#fields = ['pub_date', 'question_text']
fieldsets = [
(None, {'fields': ['question_text']}),
('Date Information', {'fields': ['pub_date']}),
]
search_fields = ['question_text']
inlines = [ChoiceInline]
Refer: C:\Python27\Lib\site-packages\django\contrib\admin\options.py
For Inlines (Tab or Stack)
def get_readonly_fields(self, request, obj=None):
fields = []
for field in self.model._meta.get_all_field_names():
if field != 'id':
fields.append(field)
return fields
def has_add_permission(self, request):
return False
Since django 2.1, you can prevent editing, while allowing viewing, by returning False
from the ModelAdmin
's has_change_permission
method, like this:
class CustomAdmin(admin.ModelAdmin):
def has_change_permission(self, request, obj=None):
return False
(This will not work before django 2.1, as it will also deny permission to any user trying only to view.)
