Django unique_together自定义错误消息

Question

I'm trying to create a custom error message for unique_together:

class Recipient(models.Model):
  mobile = PhoneNumberField()
  mobile2 = PhoneNumberField()

  class Meta:
     unique_together = (("mobile", "mobile2"),)


  def unique_error_message(self, model_class, unique_check):
    print("I don't seem to run")
    if model_class == type(self) and unique_check == ('mobile', 'mobile2'):
        return 'My custom error message'
    else:
        return super(Recipient, self).unique_error_message(model_class, unique_check)

However my error message is not running instead I get:

Duplicate entry '+4473192817212-+4478192817210' for key 'mobile'\\"

why?

Answer 1

The error message you pasted seems more like an error caused by a unique constraint on the mobile field of the recipient table, indicating that at one point you had unique=True at one point. Check for this constraint in the database or if this is just in development, delete the database and syncdb again.
