Django forms and the select field

I have the following model:

class StraightredTeam(models.Model):
    teamid = models.IntegerField(primary_key=True)
    teamname = models.CharField(max_length=36)
    country = models.CharField(max_length=36,null=True)
    stadium = models.CharField(max_length=36,null=True)
    homepageurl = models.TextField(null=True)
    wikilink = models.TextField(null=True)
    teamcode = models.CharField(max_length=5,null=True)
    teamshortname = models.CharField(max_length=24,null=True)
    currentteam = models.PositiveSmallIntegerField(null=True)

    def natural_key(self):
        return self.teamname

    class Meta:
        managed = True
        db_table = 'straightred_team'

I use this model with the following form:

from django import forms
from straightred.models import StraightredTeam

    class SelectTwoTeams(forms.Form):

        currentTeams = StraightredTeam.objects.filter(currentteam = 1).order_by('teamname')
        team_one = forms.ModelChoiceField(queryset = currentTeams, to_field_name = "teamname")

This produces the following html:

            <form action="" method="post">
                <input type='hidden' name='csrfmiddlewaretoken' value='xyz' />
                <tr><th><label for="id_team_one">Team one:</label></th><td><select id="id_team_one" name="team_one">
<option value="" selected="selected">---------</option>
<option value="Arsenal">StraightredTeam object</option>
<option value="Aston Villa">StraightredTeam object</option>
<option value="Bournemouth">StraightredTeam object</option>
<option value="Chelsea">StraightredTeam object</option>
<option value="Crystal Palace">StraightredTeam object</option>
<option value="Everton">StraightredTeam object</option>
<option value="Leicester">StraightredTeam object</option>
<option value="Liverpool">StraightredTeam object</option>
<option value="Man City">StraightredTeam object</option>
<option value="Man United">StraightredTeam object</option>
<option value="Newcastle">StraightredTeam object</option>
<option value="Norwich">StraightredTeam object</option>
<option value="Southampton">StraightredTeam object</option>
<option value="Stoke">StraightredTeam object</option>
<option value="Sunderland">StraightredTeam object</option>
<option value="Swansea">StraightredTeam object</option>
<option value="Tottenham">StraightredTeam object</option>
<option value="Watford">StraightredTeam object</option>
<option value="West Brom">StraightredTeam object</option>
<option value="West Ham">StraightredTeam object</option>
</select></td></tr>
                <input type="submit" value="Submit" />
            </form>

I would love for the "StraightredTeam object" to show the same as the value part. I.e. the name of the football/soccer team.

Any advice to point me in the right direction would be ideal, many thanks, Alan.

You need to define a __unicode__ method (or __str__ if you're using Python 3) on your model.

class StraightredTeam(models.Model):
    ...
    def __unicode__(self):   # __str__ on Python 3
        return self.teamname

Note, however, that you shouldn't be using that to_field_name attribute in the field definition. The default is to use the ID, which is the correct value to allow Django to set the foreign key correctly.

Label for choice is created in django forms by converting object into unicode (python 2.x) or string (python 3.x). If you want to display teamname here, just create __unicode__ (python 2.x, also you can create __str__ method and decorate object with python_2_unicode_compatible imported from django.utils.encoding so it will be compatible both with python 2.x and 3.x) or __str__ (python 3.x) method that will return string to display as choice label.
