Question

Another question on some forms

Here is my model

class TankJournal(models.Model):     user = models.ForeignKey(User)     tank = models.ForeignKey(TankProfile)     ts = models.IntegerField(max_length=15)     title = models.CharField(max_length=50)     body = models.TextField() 

Here is my modelform

class JournalForm(ModelForm):     tank = forms.IntegerField(widget=forms.HiddenInput())       class Meta:         model = TankJournal         exclude = ('user','ts') 

Here is my method to save it

def addJournal(request, id=0):     if not request.user.is_authenticated():         return HttpResponseRedirect('/')      #     # checking if they own the tank     #     from django.contrib.auth.models import User     user = User.objects.get(pk=request.session['id'])      if request.method == 'POST':         form = JournalForm(request.POST)          if form.is_valid():             obj = form.save(commit=False)              #             # setting the user and ts             #             from time import time             obj.ts = int(time())             obj.user = user             obj.tank = TankProfile.objects.get(pk=form.cleaned_data['tank'])              #             # saving the test             #             obj.save()          else:             print form.errors      else:         form = JournalForm(initial={'tank': id}) 

When it saves.. it complains the tank is not a TankProfile but a Integer.. how can I override the form object to make tank a TankProfile

thanks

I think you want this:

class JournalForm(ModelForm):     tank = forms.ModelChoiceField(label='',                                   queryset=TankProfile.objects.all(),                                   widget=forms.HiddenInput)
