Unique Email - allow blank

[sibe7691]

Hi, with the option REQUIRE_UNIQUE_EMAIL set to True,
Is there a way to allow emails to still be blank?

Make your emails null, not blank. An empty string is still a value in the DB, so the unique constraint will disallow you from having multiple values of the same.

Closing this issue.

Ok, but this causes problem in django admin page, since email appears to be required now, i cannot save without it complaining.

Ah, that's true. I'll look at that at some point, if you need it now, feel free to send in a PR.

I believe this could could be fixed by allowing changing this field by a setting similar to email's length and uniqueness.

One way to fix it would be to set the models .blank to be the same as the result of the call to REQUIRE_UNIQUE_EMAIL().
