9393	Overridden inherited model fields being duplicated in forms	terpsquared	nobody	"Likely related to (but distinct from) #9392, and possibly #9371.

Given an inherited model of the form:

{{{
from django.db import models
from django.contrib.auth.models import User, UserManager
from django.utils.translation import ugettext_lazy as _
from datetime import datetime


class Customuser(User):
    username = models.CharField(_('customer id'), max_length=30, unique=True, help_text=_(""Required. 30 characters or fewer. Alphanumeric characters only (letters, digits and underscores).""))
    email_id = models.EmailField(_('e-mail address'), blank=True, null=True, unique=True, db_index=True)

    def __unicode__(self):
        return u'%s' % self.username

    # Use UserManager to get the create_user method, etc.
    objects = UserManager()
}}}

A form specifying the inherited field ""username"" will display the username field twice during output. For example, 

{{{
from django import forms
from django.forms import ModelForm

class CustomForm1(ModelForm):
    class Meta:
        model = Customuser
        fields = ('username')
}}}

will result in the following html output from the form:

{{{
<tr><th><label for=""id_0-username"">Customer id:</label></th><td><input id=""id_0-username"" type=""text"" name=""0-username"" maxlength=""30"" /><br />Required. 30 characters or fewer. Alphanumeric characters only (letters, digits and underscores).</td></tr>
<tr><th><label for=""id_0-name"">Name:</label></th><td><input id=""id_0-name"" type=""text"" name=""0-name"" maxlength=""100"" /></td></tr>
}}}

Notice that this is different from #9392.  In that case, the email_id field is distinct from the email field, but both are being displayed.  In this case, both the original field and the inherited field seem to be displayed.

A solution to this would necessitate a design decision:  Only show the inherited field, provide a mechanism for specifying which field is intended, or throw an error would seem to be the best possible answers."		closed	Uncategorized	dev		duplicate			Unreviewed	0	0	0	0	0	0
