Proper Forms

A library to make far easier to create beautiful, semantically rich, syntactically awesome, readily stylable and wonderfully accessible HTML forms in your Python web application.


The main problem I used to have it was the markup.
I wanted Bootstrap classes. I wanted complex layouts like multiple columns.

How Proper Forms is different#

  • A field isn’t tied to a specific HTML tag, so can be presentend in multiple ways. Even the same form can be used in different contexts and have different widgets and styles on each. A set of options as checkboxes, a select multiple, or a comma-separated input? You got it. A date as a calendar or as three selects? No problem.

  • Many commonly used built-in validators, and you can also write simple functions to use as custom ones.

  • Any field can accept multiple values; as a list or as a comma-separated text.

  • All error messages are customizable. The tone of the messages must be able to change or to be translated.

  • Incredible easy to integrate with any ORM (object-relational mapper). Why should you need another library to do that?

Just show me how it looks#

from proper_forms import Form, Email, Text

class CommentForm(Form):
    email = Email(required=True, check_dns=True)
    message = Text(
        LongerThan(5, "Please write a longer message"),

def comment():
    form = CommentForm(request.POST)
    if request.method == "POST" and form.validate():
        data =
    return render_template("comment.html", form=form)


Install the package using pip.

pip install proper-forms
