Crispy form: how to disable/readonyl all fields?

[Paul]

I have a model that i would like to create/read/update and delete
(CRUD); i'm using generic views (create_update) to do that. Also i'm
using crispy forms to do the form (layout) styling icw twitter-
bootstrap styling. Now the thing i'm not sure about is how to do the
'read' function. I prefer to show a similar page as the update
function but then without a button and with all fields set to readonly
mode (or disabled). How could i do that with crispy forms?

I'm half way there:
- I created a form class that has the FornHelper
- From the urlconf i first route to my own view function to retrieve
the object (to read)
- Then i call object_detail (from generic views) with extra_context
that has the form initialized with the object to read: extra_context =
{'form': ReadForm(instance = object)},
- Then in the template i simply invoke crispy forms to display the
'form'

This all works but the only thing left is to disable/readonly all the
fields... how can i do that?

Thanks for any idea's

I have a sort of solution (but don't like it). I subclassed the crispy-
tag to change the input's into span's/uneditable's. This is done using
re's which is the part i don't like, it will only work as long as the
raw html is compatible with the re's....

I know a better solution is to create custom templates for the field
for example but i'm missing complete and working examples to do that;
anyone advise?

'''subclass the crispy tag to modify the tags output: each input

import re
value = super(CrispyUneditable, self).render(context)
