[Zope-CMF] Formlib implementation for folder contents

[Charlie Clark]

Hi,

now that I've had a couple of months practice with browser views in  
general and formlib in particular and also because I've got a  
particular itch to scratch I've started on a formlib version of  
folder_contents and I've now got a skeleton version of the form. Well,  
I've got the form at least!

What I've done so far:

* a view based on EditForm (haven't quite mastered redirects in  
PageForm) but not using setUpEditWidgets - I pass the field values in  
as 'data'. Fields are distinguished from each other using the prefix  
argument

    field = form.FormField(f, n, item.id) # using an interface
    self.form_fields += form.FormFields(field)

* turned the buttons into actions - probably the easiest part :-)

* generate fields (Boolean for the checkboxes)

* use a custom template to iterate through the folder items and call  
the appropriate widgets. Although this works it's a bit clumsy. This  
is the rather stripped-down HTML and I'm anticipating renaming on the  
form.

<form class="form" action="." method="post" enctype="multipart/form- 
data"
   tal:attributes="action request/ACTUAL_URL">
   <table>
     <tr>
       <th>Select</th>
       <th>Name</th>
       <th>Last Modified</th>
       <th>Position</th>
     </tr>
   <tr tal:repeat="item context/contentValues">
     <td tal:content="structure python: view.widgets['%s.select'  
%item.id]()">Checkbox</td>
     <td tal:content="structure python: view.widgets['%s.name'  
%item.id]()"></td>
     <td tal:content="item/ModificationDate"></td>
     <td tal:content="repeat/item/number"></td>
   </tr>
   </table>
<div class="buttons">
<tal:loop tal:repeat="action view/actions"
    tal:replace="structure action/render" />
</div>
</form>

While I can probably tidy this up to use a method in the view I'm not  
convinced it's entirely the right way to do this. But it works!

I'll continue working - the actions themselves should be most  
straightforward on this but would appreciate any comments.
