My forms.py:
from django import forms
from django.forms import ModelForm
from django.contrib.auth.models import User
from athletesunited.athletes.models import Athlete
# Athlete Community Choices
ATHLETECOMMUNITIESCHOICES = (('archery', 'Archery',), ('mensbasketball', 'Men\'s Basketball',), ('womensbasketball', 'Women\'s Basketball',), ('baseball', 'Baseball',), ('cardio', 'Cardio',), ('cheerleading', 'Cheerleading',), ('crochet', 'Crochet',), ('dieting', 'Dieting',), ('football', 'Football',), ('golf', 'Golf',), ('gymnastics', 'Gymnastics',), ('hockey', 'Hockey',), ('injuryrecovery', 'Injury Recovery',), ('lacrosse', 'Lacrosse',), ('lifting', 'Lifting',), ('rugby', 'Rugby',), ('racing', 'Racing',), ('swimming', 'Swimming',), ('soccer', 'Soccer',), ('skateboarding', 'Skateboarding',), ('tennis', 'Tennis',), ('wrestling', 'Wrestling',))
# Athlete Update Profile Form
class AthleteProfileUpdateForm(ModelForm):
athletebirthday = forms.CharField(label=(u'Athlete Birthday:'))
athleteurl = forms.CharField(label=(u'Athlete Url:'))
#athletecommunities = forms.MultipleChoiceField(label=(u'Athlete Communities:'), widget=forms.CheckboxSelectMultiple, required=False, choices=ATHLETECOMMUNITIESCHOICES)
class Meta:
model = Athlete
exclude = ('athleteuser',)
fields = ['athletebirthday', 'athleteurl', 'athletecommunities', 'athletecolleges',]
def selected_athlete_communities(self):
return [athletecommunities[0] for athletecommunities in ATHLETECOMMUNITIESCHOICES]
My model for the athlete:
from django.contrib.auth.models import User
# Athlete User
class Athlete(models.Model):
athleteuser = models.OneToOneField(User)
athletebirthday = models.DateField()
athleteurl = models.CharField(max_length=30) # Must limit to a-z && A-Z && and 0-9 chars
athletecommunities = models.ManyToManyField('communities.Community')
athletecolleges = models.ManyToManyField('colleges.College')
User.profile = property(lambda u: Athlete.objects.get_or_create(athleteuser=u)[0])
def __unicode__(self):
return self.athleteuser.first_name + " " + self.athleteuser.last_name
The relevant parts of my template for editprofile, just simply showing the form is all:
<form action="" method="post">{% csrf_token %}
{% for field in AthleteProfileUpdateForm %}
{{ field.label }}
{{ field }}
{{ field.error }}
<p>
{% endfor %}
<input type="submit" alt="post" value="Update" />
</form>
As you can see from the pictures, when I do athleteprofile = AthleteProfileUpdateForm(instance = profile) in my view in the picture named "showingcommunities" you can see there is this little box that has greyed out some community names. This is great and occurs when this line "athletecommunities = forms.MultipleChoiceField(label=(u'Athlete Communities:'), widget=forms.CheckboxSelectMultiple, required=False, choices=ATHLETECOMMUNITIESCHOICES)" is commented out in my update athlete profile form. I was really optimistic when I saw this as I could see that indeed I was rendering which communities the user is actually in. However, when I add this following line back to my forms "athletecommunities = forms.MultipleChoiceField(label=(u'Athlete Communities:'), widget=forms.CheckboxSelectMultiple, required=False, choices=ATHLETECOMMUNITIESCHOICES)" you would see the second picture "notshowingcommunities" because basically there are the checkboxes but the ones the user is actually in are not rendering. What I mean is the checkboxes that correspond to what communities the user selected do not show up as checked. They all show up as empty.
I have used a BooleanField before as a flag and it does hold its value, I can see the checked box in i.e. an edit form if on creation of that object the user checks the box. I would really hate to have to make about 20 boolean fields for an athlete to correspond to my communities. Not to mention every time I want to add a community I would have to add more fields on the model, when I'd prefer to just add to my ATHLETECOMMUNITIESCHOICES the new communities. I've been trying a lot but I really can't seem to find a resource that helps me simply just render what options were selected on this multiplechoicefield, I tried modelmultiplechoicefield as well.
Thanks for helping, also if you have a better and nicer form concept I can try please let me know. Even though these checkboxes could work I'm not super satisfied with how this looks, I'd have to think up more ideas probably because I don't usually build websites that require an interface with a large relationship such as my athlete being in multiple communities and selecting and deselecting.

I know it's sort of a need by case basis but has anyone tried to do this before? Has anyone tried to render the choices a user has selected previously by rendering checked check boxes on a multiple choice field?
Thanks,
JJ
