Admin read-only fields should be included in POST

[Jonas H.]

Fields marked readonly in the admin are not included in the POST in case the model is saved. Now if such field does not have @blank=True@, the form doesn't validate since a non-blank field is missing a value.

These values should be included in the form as hidden fields.

Fields listed in readonly_fields are excluded from the default model form build by the admin, therefore they do not need to be in POST in order for the form validation and model save to succeed, see ​https://docs.djangoproject.com/en/1.5/ref/contrib/admin/#django.contrib.admin.ModelAdmin.readonly_fields. I just tried this and it works fine to edit-and-save a model with a readonly field (that already has a value in the field), there is something beyond a simple readonly field and default admin here that led to the assertion that values were needed in POST. Without knowing the specifics of the situation though, it's hard to guess whether there is a bug in Django or a mis-use/misconfiguation in the model admin using readonly_fields.

Sorry. Seems to have been an issue with my code.
