I have extended *pyramid_deform.FormView* for my add/edit views in my app.
I can add records to the db alright but on the edit page, the form doesn't
get populated by the data in the *appstruct* . The code for the add/edit
views together with my view registration code is shown below:
# ======== import statements, file: views.py =============

> def get_appstruct(context, schema):
>

>
> return appstruct
>
> class UserEditPage(FormView, Dashboard):

>

>
> form_options = (('formid', 'new-user'), ('method', 'POST'),
>> ('bootstrap_form_style', 'form-vertical'))
>
> title = u'Edit User'

*- *I am completely lost when it comes to the workings of
the overridden method* *UserEditPage::appstruct(). Although, I do
understand that it's a dict of data I wish to prefill the form with.
*- *Am I supposed to make a call to the db to retrieve the data to populate
appstruct?
*Would anyone be kind enough to help me figure out what I am doing wrong
here? Thanks so much.*
