Hi,
I need to make a complex form this week. I need to do the same form as
the contact advanced search inside thunderbird. For those who doesn't
know it here is a screen shot:
http://nsit.uchicago.edu/img/email/tbird-advanced-search.png
The form is built by the user. He can add form fields define 'where' to
search, ...
Do you mean that you want an admin user to be able to change the
schema (fields) through a web UI?
If so I don't think z3cform is for you. That is purely a code based
way setting up a form.
You want PloneFormGen if you want a to email the result or store the
information in a simple table. Otherwise I believe dexterity has a TTW
schema editing interface right? or at least planned to.
My question is:
* Could I use z3cform to do this ? I have tried it but I need to define
a schema. But in my case, I don't know the schema ... it seems not the
good way
* CMF FormController. I know how to do it with this technology, but it
seems very old and I want my product to be fashionned and have a good
future.
* By hand ? Coding every things and do not use any other technologies
than browserview.
* Any other idea ?

No. I mean the user build the form. He is able to add or remove form
field. What is a form field in this case: It is a set containing those
things:
A select input with all indexes as options.
A select input with constraints as options.
An input type text where the user put the value he wants to search for.
The UI give the user the ability to add/remove as many form field as he
wants throw two buttons: 'more' and 'fewer'.
But you have answered at one question: z3cform seems not appropriate. It
is better for 'static' forms.
I'm not sure. You can change the set of fields and widgets quite easily
in the update() method (or one of the methods it calls), e.g. in
response to something in the request.
z3c.form would mainly give you fields, widget and validation. How you
construct the set of fields is up to you. The most common (and most
documented) pattern is to use an interface, but zope.schema fields can
exist without an interface and forms can be constructed without a context.
But you should expect to spend a few days figuring out z3c.form. I'm not
aware of any documentation or examples that cover your use case.
