I'm a bit of a newbie when it comes to django, ajax, and jquery, so i apologize ahead of time if my question comes off being trivial.
I've been scratching my head on this one for some time now, but I am trying to use ajax and jquery to submit a Django ModelForm form via a modal dialog window provide by jQuery UI. The problem I am having is that it seems that the form data isn't being passed into the request or that my form object in my views.py file is having a problem parsing the reqest.POST object. Regardless when I submit my form, the form.is_valid() fails and reviewing the form errors I get a "This field is required" for every input of the form. So not sure what I am doing wrong, the form in question worked prior to me trying to "modal"ize it with ajax.
here's my code, maybe a more seasoned eye can see what I missed.
forms.py
from django.forms import ModelForm
from artists.views import Artist
class RegistrationForm(ModelForm):
username = forms.CharField(label=(u'User Name'))
first_name = forms.CharField(label=(u'First Name'))
last_name = forms.CharField(label=(u'Last Name'))
email = forms.EmailField(label=(u'Email'))
password = forms.CharField(label=(u'Password'),
widget=forms.PasswordInput(render_value=False))
password = forms.CharField(label=(u'Verify Password'),
widget=forms.PasswordInput(render_value=False))
class Meta:
model = Artist
exlude = (user, slug, work_email)
views.py
from django.http import HttpResponse
from django.contrib.auth.models import User
from django.shortcut import render
from django.template.defaultfilters import slugify
from django.utils.functional import Promise
from django.utils.encoding import force_text
from django.shortcuts import render
from artists.forms import RegistrationForm
from artists.models import Artist
import json
class LazyEncoder(json.JSONEncoder):
def default(self, obj):
if isinstance(obj, Promise):
return force_text(obj)
return super(LazyEncoder, self).default(obj)
def ValidateEmail(email):
from django.core.validators import validate_email
from django.core.exception import ValidationError
try:
validate_email(email)
return True
except ValidationError:
return False
def ArtistRegistration(request):
form = False
if request.method == 'POST' and request.is_ajax():
form = RegistrationForm(request.POST)
if form.is_Valid():
is_valid = True
username = form.cleaned_data['username']
password = form.cleaned_data['password']
password1 = form.cleaned_data['password1']
email = form.cleaned_data['email']
first_name = form.cleaned_data['first_name'].title()
last_name = form.cleaned_data['last_name'].title()
if ValidateEmail(email) is False:
is_valid = False
message = "Email entry is invalid."
if User.objects.filter(username=username).exists():
is_valid = False
message = "Username already exists."
if password != password1:
is_valid = False
message = "Passwords do not match."
if is_valid is False:
response_dict = {"type": "error"}
response_dict["message"] = message
result = json.dumps(response_dict, cls=LazyEncoder)
return HttpResponse(result, mimetype='application/json')
else:
user = User.objects.create_user)
username = username,
email = email,
password = password,
first_name = first_name,
last_name = last_name_
user.save()
artist = Artist(
user = user,
first_name = first_name,
last_name = last_name,
work_email = email,
slug = slugify('%s %s' % (first_name, last_name)),
department=form.cleaned_data['department'])
artist.save()
response_dict = {'status':1, 'type':'success'}
result = json.dumps(response_dict, cls=LazyEncoder)
return HttpResponse(result, mimetype='application/json')
else:
response_dict = {'type': 'error'}
response_dict['message'] = 'form is invalid'
response_dict['errors'] = json.dumps(form.errors)
result = json.dumps(response_dict, cls=LazyEncoder)
return HttpResponse(result, mimetype='application/json')
else:
form = RegistrationForm()
context = {'form' : form}
return render(request, 'register-modal.html', context)
here is the html that my modal dialog calls: register-modal.html
<form action="{% url 'modal_registration' %}" method="post" id="register_form" name="register_form">
{% csrf_token %}
<table>
<tbody>
<tr>
<th><label for="first_name">First Name:</label></th>
<td>{{ form.first_name }}</td>
</tr>
<tr>
<th><label for="last_name">Last Name:</label></th>
<td>{{ form.last_name }}</td>
</tr>
<tr>
<th><label for="email">Email:</label></th>
<td>{{ form.email }}</td>
</tr>
<tr>
<th><label for="username">Username:</label></th>
<td>{{ form.username }}</td>
</tr>
<tr>
<th><label for="password">Password:</label></th>
<td>{{ form.password }}</td>
</tr>
<tr>
<th><label for="password1">Verify Pswd:</label></th>
<td>{{ form.password1 }}</td>
</tr>
<tr>
<th><label for="department">Department:</label></th>
<td>{{ form.department }}</td>
</tr>
</tbody>
</table>
</form>
<span id="registration_error" name="registration_error" style="color: #FF0000;"></span>
Finally here is the js file that makes all the jquery and ajax calls. I've omitted the csrf part because its copied verbatim from the Django docs.
register.js
$(document).ready(function () {
$.ajaxSetup({traditional: true});
var $register_dialog = $('#modal_register_div').dialog({
autoOpen: false,
title: "User Registration",
closeOnEscape: true,
draggable: false,
resizable: false,
modal: true,
width: 450,
buttons: {
"Register": function () {
var $this = $(this);
var frm = document.form['register_form'];
$.ajax({
type: frm.method,
url: frm.action,
data: $('#register_form').serialize(),
contentType: "application/json;charset=utf-8",
dataType: 'json',
success: function(response){
if(response['type'] == 'success') {
//any extra success functionality goes here
$this.dialog("close");
} else {
$("#registration_error").html(response['message']);
console.log(response['errors']);
}
},
error: function(xhr, ajaxOptions, thrownError) {
alert(thrownError + '\n' + xhr.status + '\n' + ajaxOptions)
}
});
return false;
}
}
});
$('#register_artist').live("click", function () {
$.ajax({
type: 'get',
dataType: 'html',
url: '/register/'
data: {},
success: function(response){
$register_dialog.empty().html(response).dialog('open');
}
});
});
});
the modal dialog is tied to a hidden div on the base template page for my django page, and the js script is loaded on the same page. the dialog is called by clicking on a null href link. anyrate, if anyone can see what I am doing wrong, your input would truly be appreciated.
Thanks!
