Using Ajax FormsΒΆ
To create a form object that uses AJAX, you can do the following.
from deform import Form
myform = Form(schema, buttons=('submit',), use_ajax=True)
Creating a Form Object indicates how to create a Form object based on
a schema and some buttons. Creating an AJAX form uses the same
constructor as creating a non-AJAX form. The only difference between
the example provided in the Creating a Form Object section and the
example above of creating an AJAX form is the additional
use_ajax=True
argument passed to the Form constructor.
If use_ajax
is passed as True
to the constructor of a
deform.Form
object, the form page is rendered in such a way
that when a submit button is pressed, the page is not reloaded.
Instead the form is posted, and the result of the post replaces the
form element's DOM node.
Examples of using the AJAX facilities in Deform are showcased on the https://deformdemo.pylonsproject.org demonstration website:
Note
As with widgets, you must ensure the required JavaScript files are included for the AJAX functionality to work. See Widget Requirements and Resources for a way to detect which JavaScript libraries are required for a particular form rendering.
