For example:
I have a user that wants to create a contact form for their personal website. They want three input type=text and one textarea and they specify a label and an name/id for them on my site. Then they can use this form on their site, but I will handle it on mine?
Is it possible for django to spit out custom forms specified by the user?
Edit: If django is too "locked down" what would you recommend I do? I would like to stay with python.
something like http://code.google.com/p/django-forms-builder or one of the million similar addins?
(made into answer at OP's request)
For this you would have some kind of editor that would create a html string. This string would be stored into your database and then upon request you would display it on the user's site.
The editor should be very strict into what it can add and what the user has control over, there are some javascript editors available that will be able to provide this functionality.
The only issue I can think of is that you may run into django escaping the form when displayed to the page.

I am looking for ways to best handle a single form on multiple pages. Like how a newsletter signup might be on a home page, an about page, and several blog pages.
I've handled this exact scenario in these 2 ways.
Write an API (using DRF) that takes a POST request, and then point the normal HTML form at that API. This works, and is very flexible, but feels like overkill.
Pass the form object into the context of each view I want the form to be on, and then include that into the template with includes form_snippet with form=form
The first approach is more flexible with wagtail, wherein all that needs to happen on the admin side is an inclusion of the newsletter as a snippet, where the admin user is able to choose if they want the newsletter on the page or not.
While both approaches work just fine, neither of them "feels" right, as I would think there is a simple way to do this without creating a big API, or passing around the form object to every single view.
three years later on you probably found an answer.
For documentation purposes and Google searchers, Wagtail offers an explanation on how to make a multiple step form here:
https://docs.wagtail.org/en/v3.0.1/reference/contrib/forms/customisation.html#multi-step-form
I did this with a contact formular. I handled it with a new app for my contact formular.
In this contactApp is the templates/contactForm.html. To include this contactForm where I want I use {% include 'contact/contactForm.html' %} so it loads the contactForm.html from my app called contact.
The question says it all,
For example,
In a contact book if someone has multiple addresses with each address having multiple fields I want to display an "add another address" button. This button would add another address form. (I want one round trip to the server, I do not want javascript or webforms2.)
It would be nice if some built in library would support this. Examples are appreciated.
Thanks.
Try django-formsets, and if you want dynamic behavior use this http://code.google.com/p/django-dynamic-formset/
I need to be able to create forms from admin panel. Process would look like this:
I click on "Add form" then I enter email to which the form should be sent and of course several fields (probably thanks to inlines) consisting of field name, type and if it is required. User should be able to view and fill the form and submit it and the data should be sent to the email given in admin.
Everything looks pretty straightforward but from my point of view it need some metaclass programming skills.
Could anyone point me to a goot form builder for Django or at least hand some tips about creating such thing? I found django-forms-builder but it is a bit too restricted imho.
I know this one's a few months old but I just though I'd post an update here anyway for anyone else that comes along.
django-forms-builder has just been rewritten to do exactly what you were looking for when you originally posted this question.
You can find the new version at http://github.com/stephenmcd/django-forms-builder or http://bitbucket.org/stephenmcd/django-forms-builder
There are many alternatives, although not many of them are actively maintained:

If you want to have a full control of what's happening (change fields for your needs or add new ones, add captcha or honeypot, add custom handling of form data, use form wizards or even use your forms via web REST API), use django-fobi https://pypi.python.org/pypi/django-fobi
While looking across the Django documentation, I came across the FormPreview.
The description says this:
Django comes with an optional “form preview” application that helps automate the following workflow:
“Display an HTML form, force a preview, then do something with the submission.”
What is meant by "force a preview"? What would you use this feature for an in application?
To force a preview means the users are forced to see the value they have inserted on the form input fields, before django actually saves it to the database.
One example is django comment system, which enforce the users to take a look at the comment they have written before django actually saves it to the database. You would see that the users are redirected to another page to take a look at their comment, and after that there is a submit button to actually save the comment.
I think they mean (I use django but I didn't know of this until now..) that you can let people write, for example in a textarea box like I'm doing right now. After the user submits it the system would preview it to the user and give him the chance to read and edit what he submitted, before it being submitted again all the way to the database.
I just started to use django. I came across forms and I need to know which one is the better way to validate a forms. Would it be using django forms or should we use javascript or some client side scripting language to do it?
You should ALWAYS validate your form on the server side, client side validation is but a convenience for the user only.
That being said, Django forms has a variable form.errors which shows if certain form fields were incorrect.
{{ form.name_of_field.errors }} can give you each individual error of each field that's incorrectly filled out. See more here:
http://docs.djangoproject.com/en/dev/topics/forms/
There's a pluggable Django app (django-ajax-forms) that helps validate forms on the client side through JavaScript. But as AlbertoPL says, use client side validation only as a usability measure (e.g. telling a user that his desired username is already taken without reloading the registration page). There are all kind of ways to sidestep client side validation, in most cases as simple as deactivating JavaScript.
Generally speaking: presume all data coming from the outside as faulty until validated.
Just came accross django-floppyforms, which seems to do clientside validation by default. They use HTML5 which supports clientside validation by default. Not sure if they also use javascript though if the browser doesn't support HTML5. Haven't tried it myself yet.
Link to django-floppyforms: Documentation and Github
If you are using bootstrap then you can simply add required attribute in forms field. For example if there is programe field then you can validate it like:
In forms.py:
programme = forms.ChoiceField(course_choices,required=True, widget=forms.Select(attrs={'required':'required'}))
Note: It requires to link to bootstrap files in your .html page of that form.
You will need to do this is JS. This app integrates forms with parsley.js to tag the forms with correct data-* attributes automatically.
