I have a Team model whit players ManyToManyField, and I want to be able to add Players to a new team when created, but not able to modify it after created.
If I make the players field readonly like this:
# admin.py class TeamAdmin(admin.ModelAdmin) readonly_fields = ['players'] admin.site.register(Team, TeamAdmin) I will not be able to add players to a new Team. How can I make the players field "readonly after created" or something like that?

django-forms Using Model Form Making fields not editable Django 1.9 added the Field. disabled attribute: The disabled boolean argument, when set to True, disables a form field using the disabled HTML attribute so that it won't be editable by users.
The simplest way is by using the field option blank=True (docs.djangoproject.com/en/dev/ref/models/fields/#blank).
Since Django 1.8 released, you can use from_db classmethod to cache old value of remote_image. Then in save method you can compare old and new value of field to check if the value has changed. @classmethod def from_db(cls, db, field_names, values): new = super(Alias, cls).
Django admin by default shows all fields as editable and this fields option will display its data as-is and non-editable. we use readonly_fields is used without defining explicit ordering through ModelAdmin or ModelAdmin. fieldsets they will be added. Now we make the Question text fields read-only.
You need to override get_readonly_fields() method of your admin class.
# admin.py class TeamAdmin(admin.ModelAdmin) ... def get_readonly_fields(self, request, obj=None): if obj: #This is the case when obj is already created i.e. it's an edit return ['players'] else: return [] If you love us?
