i'm moving my first steps into Django and i'm tryin' to follow the tutorial at this link: https://docs.djangoproject.com/en/dev/topics/forms/modelforms/ but i can't get a form. It just returns a white page!
Can someone explain if i'm missing something?
my models.py:
from django.db import models
from django.forms import ModelForm
class UserProfile(models.Model):
name = models.CharField(max_length=30)
surname = models.CharField(max_length=30)
email = models.EmailField()
tel = models.CharField(max_length=30, null=True, blank=True)
def __unicode__(self):
return '%s %s' % (self.surname, self.name)
class Ad(models.Model):
title = models.CharField(max_length=50)
descr = models.TextField()
city = models.CharField(max_length=30)
price = models.FloatField(null=True, blank=True)
img = models.ImageField(upload_to='./uploaded_imgs', null=True, blank=True)
dateIn = models.DateField(auto_now_add=True)
dateExp = models.DateField(auto_now_add=True)
codC = models.ForeignKey('Cat')
codU = models.ForeignKey('UserProfile')
def __unicode__(self):
return '%s - %s' % (self.title, self.dateIn)
class Cat(models.Model):
cat = models.CharField(max_length=35, primary_key=True)
def __unicode__(self):
return self.cat
my forms.py:
from django import forms
class newAdForm(forms.Form):
title = forms.CharField(max_length=50)
descr = forms.CharField(widget=forms.Textarea)
city = forms.CharField(max_length=30)
price = forms.FloatField(required=False)
img = forms.ImageField(required=False)
dateIn = forms.DateField(auto_now_add=True)
dateExp = forms.DateField(auto_now_add=True)
codC = forms.ModelChoiceField(Cat)
codU = forms.ModelChoiceField(UserProfile)
my views.py:
from django.contrib.auth import authenticate, login, logout
from django.contrib.auth.models import User
from django.shortcuts import render_to_response, get_object_or_404, redirect
from django.template import RequestContext
from django.http import HttpResponse
from django import forms
from models import *
from django.forms import *
from django.forms.models import modelformset_factory
[...]
def newAd(request):
newAdFormSet = modelformset_factory(Ad)
if request.method == 'POST':
formset = newAdFormSet(request.POST, request.FILES)
if formset.is_valid():
formset.save()
return render_to_response('conf.html', {'state':'Your ad has been successfull created.'}, context_instance = RequestContext(request),)
else:
formset = newAdFormSet()
return render_to_response('ad_form.html', context_instance = RequestContext(request),)
my ad_form_auto.html template:
{% extends "base.html" %}
{% block title %}Ads insertion form{% endblock %}
{% block content %}
{% if error_message %}
<p><strong>{{ error_message }}</strong></p>
{% endif %}
<form method="post" action="">
{{ formset }}
</form>
{% endblock %}
Thanks a lot! This community looks just awesome! :)
You're not passing the form to the template - at present your 'formset' variable containing the form isn't included in the datadict being passed to the view.
return render_to_response('ad_form.html', context_instance = RequestContext(request),)
Should include the data (see render_to_response() docs) here I've renamed the form in your data and to your template as 'form' for ease of nomenclature:
return render_to_response('ad_form.html',
{'form':formset},
context_instance=RequestContext(request))
Then, in your template (see forms in templates docs) replace {{formset}}
with {{form.as_p}}
. Also add a submit button to the form.
<form action="" method="post">
{% csrf_token %}
{{ form.as_p }}
<input type="submit" value="Submit" />
</form>
