Django multiple forms 1 view..Form errors issue
You don't have any case in which you're displaying an empty formtwo. Passing request.POST to the form and calling is_valid() is going to cause validation to run, which presumably isn't what you intend when the user POSTS formone. As @karthikr suggests, you need to figure out a way to tell what step you're so you can validate and display the appropriate form. The easiest way might be to add something like args['step'] = 1 when rendering book_post.html and args['step'] = 2 when rendering book_post_form2.html. Then pass that variable back to the server again on POST using a hidden form field, and check it to decide which form you need to validate.

Subclassing django-registration 1.0 forms for django 1.5 custom user models
Some parts are most definitely not Django 1.5 compatible yet: https://bitbucket.org/ubernostrum/django-registration/src/8f242e35ef7c004e035e54b4bb093c32bf77c29f/registration/forms.py?at=default#cl-48 class RegistrationForm(forms.Form): # ... def clean_username(self): # ... # The line below needs fixing existing = User.objects.filter(username__iexact=self.cleaned_data['username']) if existing.exists(): raise forms.ValidationError(_("A user with that username already exists.")) else: return self.cleaned_data['username'] So unless those methods are changed and/or you subclass them, it won't work yet.

When you create a User, you can give different access to any part of your app in the user permission tab. This mechanism should do what you want. If you want to go further and play with the display of your app while keeping something similar to the django admin, you can use the templates of django admin in a view in order to give access to only a part of your model and add more design and custom functions. In this case, I'll suggest you to make a copy of the templates located in djangocontribadmin emplatesadmin and then you can modifiy them as you want.

Django: How to use django.forms.ModelChoiceField with a Raw SQL query?
Are you sure you actually need a raw query there? Just looking at that query, I can't see any reason you can't just do it with filter(location__city=city_id, available_reserves__gte=0, datetime_from__gt=datetime.datetime.now()). Raw query sets are missing a number of methods that are defined on conventional query sets, so just dropping them in place isn't likely to work without writing your own definitions for all those methods.

How can I trigger non-blocking errors in Symfony2 forms?
You could introduce 2 different validation groups for your form. One for the "real" validation and another one for the warnings. You can also manually add errors in your controller: $form->get('form-field')->addError(new FormError('field error message')); or global errors: $form->addError(new FormError('form error message'));

Django Userena - Correctly override default django app templates?
Is probably because you don't have any TEMPLATE_DIRS defined in settings.py. Modify it to this: TEMPLATE_DIRS = ( # Put strings here, like "/home/html/django_templates" or "C:/www/django/templates". # Always use forward slashes, even on Windows. # Don't forget to use absolute paths, not relative paths. 'full/path/to/your/templates/dir', ) TIP: Normally, it's a good practice to avoid hard coding paths. You can do this trick instead to get the full path to the templates dir (or whatever path needed) and keep your project portable: import os settings_dir = os.path.dirname(__file__) PROJECT_ROOT = os.path.abspath(os.path.dirname(settings_dir)) ...

What is the use of forms.py in django
Making models and views "dumb" is by choice: If you use a specific file like "forms.py" where you have your form classes together with their validations, it is much easier and especially faster to unit test these forms than having to use Django's test client. The same goes for models: Any complicated algorithms usually go into a "utils.py" (or similarily named) file, so this can be tested easier. And lastly, when the size of your views.py or models.py file gets larger and larger over time, it is a bit annoying to scroll around the file all the time.

Django Forms - Many to Many relationships
I'd start by renaming category in the model to categories, and updating the related code accordingly - the singular naming is just going to be a continuous headache. At that point, you're pretty close. In your success branch when submitting an article, assign the categories as a separate statement. article = Article.objects.create( title=form.cleaned_data['title'], body=form.cleaned_data['body'] ) # note changed plural name on the m2m attr & form field article.categories.add(*form.cleaned_data['categories']) # alternately # for cat in form.cleaned_data['categories']: # article.categories.add(cat) return redirect('article_index') # Redirect after POST Oh, and, kudos on avoiding ModelForm.

TypedChoiceField is just like ChoiceField, except ChoiceField always return unicode. With TypedChoiceField you pass a function that takes one argument and returns the value cast to the type you want. For example, if you want to coerce the value to integer, use: int_field = forms.TypedChoiceField(choices=SOME_CHOICES, coerce=int) The field value will always be an integer or fail validation.

Gathering information from few forms in django
I think this would be most easily solved by making a form which includes both the search term and any filters; you can place the form elements wherever you want. Your form would have to be something like: from django import forms class MySearchForm(forms.Form): FILTERS = (("lt20", "Less than 20"), ("20to50", "Twenty to fifty"), ) term = forms.CharField() filters = forms.MultipleChoiceField(widget = CheckBoxSelectMultiple, choices = FILTERS) Then you would have to display the form manually, so you can split it up however you want in the template. In other words, instead of using a filter like {{form.as_p}}, you would have to do {{form.term}} and {{form.filters}}. You could also define your filters in a model, so that yo

Javascript driven forms in Django
So you want to validate something in JS before submitting. Here's one way to do that. Instead of putting an input of type submit in the form you should put a button of type button: <form id="my-form" submit="..."> ... <input type='button' id='submit-button' value="Save"> </form> Note that unless you specify the type as "button", it will still try to submit. Then in a JS file you write something like this (include jQuery in your HTML file): $('#submit-button').click(function() { var errors = testErrors(); // this function tests for the errors. if (errors != "") { alert(errors); } else { $('#my-form').submit(); } } Example testErrors(): function testErrors() { var country = $("#id_country").val(); var city = $("

Django: How are forms related to models?
Conceptually, forms serve as the handler for inputting data in your HTML in order to use that data somewhere in your application (in your views). You'll find two common uses for forms in Django: working with your models (data defined by your database) or for the purposes of accomplishing some kind of task (like sending an e-mail - where you don't necessarily need to have an associated model). Forms do a lot of things for both of these functions. These range from modularity, extensibility and ease of management (as they can be easily defined, interchanged, inherited etc. in Python) to validation (one of the biggies). Validation is crucial - and it's probably what you are referring to in terms of registration. Django Forms will validate against a definition either defined in your Form cl

How to integrate JS frameworks with django forms
I would do this simply by adding the <script> and <style> tags required by select2 in a {% block extra_header %} inside the template where the form is rendered. Those script tags should load the select2 library and run it for the select box directly in the client side (no server side changes are required IMHO). Any DOM changes that may be required should also be done in those scripts (this keeps the new feature encapsulated and isolated). The {% block extra_header %} should load directly into the <header> section of the main template.

The dot is very important. Are your forms actually named: "FormVP" Or just "VP" (etc...) If the later then you will have to call them as: Form.VP and not FormVP.

Overloading error messages in Django forms
They depend on the field and the validators that field implements. You can see what you can expect if you search for "default_error_messages" in the fields.py in the django source: https://github.com/django/django/blob/master/django/forms/fields.py For example, the CharField implements two extra validators MaxLengthValidator and MinLengthValidator so if you want to override the messages for those errors (in the case they are raise), you can add to your error_messages: error_messages : { 'min_length' : '...', 'max_length' : '...', }
