Re: [Zope3-Users] Form for list of lists
Thanks (roger) for the tips. I was trying to use a single custom widget
- taking that out gave the expected default behaviour. I needed a much
more customised form, so after many false steps, and for the benefit of
anyone else who needs to know this is what I did:
1. Put an 'update' method definition in the thingy content type
Interface and Class Implementation.
2. Created a custom thingy Page Template for the edit form.
3. Used template="thingy_template.pt" and
class="site.thingy.thingyClass" definitions in the editform
configuration. (No custom widgets.)
Seems very simple! I guess the problem for the Zope 3 newcomer is
knowing which bits if the framework to use and which to replace.

Subject: [Zope3-Users] Form for list of lists
I have a list of lists that I need to manipulate with a form. I have
figured out how to get the list elements into a form with a Page
Template. However, the field names come out like this:
0 field.listname.0. field.listname.1. field.listname.2.
1 field.listname.0. field.listname.1. field.listname.2.
2 field.listname.0. field.listname.1. field.listname.2.
...
where the first integer is just the value of
repeat/item/index and the
first element represents listname[0][0].
I have a widget derived from SimpleInputWidget to handle the form
elements (all strings).
I don't know how to get the updated form values back into the list of
lists, or even the best/correct approach to this whole problem. Can
anyone provide some pointers?
Use the Field "List" in your interface for describe the list attribute.
Then use the standard "editform" directive with the right schema and
all is handled by the form framework.
Then you should get values like:
field.list.0.name.0 field.list.0.name.1 field.list.0.name.2
field.list.1.name.0 field.list.1name.1 field.list.1.name.2
If you like to use a own edit form, you can call
request.get('yourfieldname', None)
for get a value. But make sure the fields have unique numbers.
Right now it seams each row uses the same numbers.

off-list? I will be doing the same thing next and was
interested in any
answers.
