Form Library for Pyramid on Python 3

[denys_br]

Is there good replace for pyramid_simpleform that works on Python 3?

[Robert Forkel]

deform [1] should work with python3. But not having used simpleform
myself I cannot say whether it's a good replacement. From my
experience I'd say if you need full control of the HTML generated by
the form lib, deform may not fit the bill.

I disagree. It is rather easy to customize deform to use a different template.
In common cases, it is as simple as copying the template from deform
into your own project and modifying it. Adjusting the template path
accordingly will cause deform to pick up your override. See the
deform_bootstrap package for an example.

One-off customizations can also be achieved with slightly more
digging, passing a custom template keyword to the constructor for any
widget.

You are right. There are ways to customize the HTML generated by
deform - and I'm using all the mechanisms you enumerated and quite
like it. But there certainly are things that are hard to achieve. E.g.
if you don't like the approach of pretty much all form items being
generated as li elements within ul containers you'd have to replace
quite a few templates, or if you want some controls being rendered
side by side, others below each other, or if you want custom sequence
widgets. But possibly these things are hard with other form libraries
as well.

I have experienced some of this pain.  Please let us know if you find compelling alternatives.

right now, at my workplace we are still on deform, but explore the
possibility of custom widgets.
E.g. we build widgets that will take a sqlalchemy model instance and
render multiple form items to edit it.
This does still feel like too much code for what we want to achieve,
but there's potential to factor out boilerplate code (like wrapping
all form items in a mapping).
Of course this means that select boxes or text inputs are created in
more than one place/template, but then again, this kind of control was
why we started down that road.
We don't have custom widgets yet, that are as complex as comprising
sequences, and i guess at this point we will look for alternatives
again.
