Historically Django has used concatenation of strings to render its forms with various as_* methods to render forms in different styles. While great to get a project up and running many folk will have used a third party library to help ease customisation of forms.
During the 4.x series a number of changes have been made including a switch to use the template engine to render forms, the ways in which the template can be set has grown and a new default style will replace as_table from Django 5.0.
We’ll cover:
⁃ What is a form, a field and a widget? What common attributes can I set to avoid logic in my template?
⁃ The switch to template based rendering, and that a template can now be used to render your form. We’ll work through a concrete example how this can be used simplify logic in your templates.
⁃ How the rendering of your form can be set on a per-project, per-form and per-instance basis.
⁃ Introduction of a new as_div template style, and why the other styles are no longer recommended.
⁃ Future ideas on how Django can ease form rendering further.
⁃ So with all this change, do I still need 3rd-party package such as crispy-forms?
May your form be good!
