I get a “Permission matching query does not exist” exception

Sometimes Django decides not to install the default permissions for a model and thus the change_profile permission goes missing. To fix this, run the check_permissions in Commands.. This checks all permissions and adds those that are missing.

I get a “Site matching query does not exist.” exception

This means that your settings.SITE_ID value is incorrect. See the instructions on SITE_ID in the [Installation section](http://docs.django-userena.org/en/latest/installation.html).

<ProfileModel> is already registered exception

Userena already registered your profile model for you. If you want to customize the profile model, you can do so by registering your profile as follows:

# Unregister userena's

# Register your own admin class and attach it to the model

Can I still add users manually?

Yes, but Userena requires there to be a UserenaSignup object for every registered user. If it’s not there, you could receive the following error:

Exception Type: DoesNotExist at /accounts/mynewuser/email/

So, whenever you are manually creating a user (outside of Userena), don’t forget to also create a UserenaSignup object.

How can I have multiple profiles per user?

One way to do this is by overriding the save method on SignupForm with your own form, extending userena’s form and supply this form with to the signup view. For example:

def save(self):
    """ My extra profile """
    # Let userena do it's thing
    user = super(SignupForm, self).save()

    # You do all the logic needed for your own extra profile
    custom_profile = ExtraProfile()
    custom_profile.extra_field = self.cleaned_data['field']

    # Always return the new user
    return user

Important to note here is that you should always return the newly created User object. This is something that userena expects. Userena will take care of creating the user and the “standard” profile.

Don’t forget to supply your own form to the signup view by overriding the URL in your urls.py:

 {'signup_form': SignupExtraProfileForm}),

How do I add extra fields to forms?

This is done by overriding the default templates. A demo tells more than a thousand words. So here’s how you add the first and last name to the signup form. First you override the signup form and add the fields.

from django import forms
from django.utils.translation import ugettext_lazy as _

from userena.forms import SignupForm

class SignupFormExtra(SignupForm):
    A form to demonstrate how to add extra fields to the signup form, in this
    case adding the first and last name.

    first_name = forms.CharField(label=_(u'First name'),

    last_name = forms.CharField(label=_(u'Last name'),

    def __init__(self, *args, **kw):

        A bit of hackery to get the first name and last name at the top of the
        form instead at the end.

        super(SignupFormExtra, self).__init__(*args, **kw)
        # Put the first and last name at the top
        new_order = self.fields.keyOrder[:-2]
        new_order.insert(0, 'first_name')
        new_order.insert(1, 'last_name')
        self.fields.keyOrder = new_order

    def save(self):
        Override the save method to save the first and last name to the user

        # First save the parent form and get the user.
        new_user = super(SignupFormExtra, self).save()

        # Get the profile, the `save` method above creates a profile for each
        # user because it calls the manager method `create_user`.
        # See: https://github.com/bread-and-pepper/django-userena/blob/master/userena/managers.py#L65
        user_profile = new_user.get_profile()

        user_profile.first_name = self.cleaned_data['first_name']
        user_profile.last_name = self.cleaned_data['last_name']

        # Userena expects to get the new user from this form, so return the new
        # user.
        return new_user

Finally, to use this form instead of our own, override the default URI by placing a new URI above it.

 {'signup_form': SignupFormExtra}),

That’s all there is to it!
