[Zope3-Users] Still trying am to build an EditForm

[Florian Lindner]

Hello,
I am still trying to build an EditForm using z3c.form. Since my previous 
thread is rather old I dare to open a new one.

I've tried a number of variations and will post the one which is the closest 
to the example.

This is the interface:

class IBlogEntry(IContainer):
    """Interface for blog entry objects."""
    contains(IBlogComment)
    
    title = TextLine(
        title = _(u"Blog entry title"),
        description = _(u"Blog entry title."),
        default = u"",
        required = True)

    content = Text(
        title = _(u"Blog entry content"),
        description = _(u"Blog entry content."),
        default = u"",
        required = True) 
        
    inputType = Choice(
        title = _(u"Type of input"),
        description = _(u"Specify the input type"),
        required = True,
        default = u"reStructeredText",
        values = [u"reStructeredText", u"HTML"] )

The view is configured like that:

    <z3c:pagelet
        name="EditEntry.html"
        for="..interfaces.IBlogEntry"
        class=".views.EditEntry"
        permission="Blog.EditEntry"
        layer="Blog.interfaces.IBlogLayer"
    />

The code in .views.EditEntry is:

class EditEntry(layout.FormLayoutSupport, form.EditForm):
    fields = field.Fields(IBlogEntry).select("title", "content")    

The layer is registered like that:

    <interface
        interface=".interfaces.IBlogLayer"
        name="BlogSkin"
        type="zope.publisher.interfaces.browser.IBrowserSkinType"
    />

and

class IBlogLayer(IFormLayer, IPageletBrowserLayer):
    """Demo browser layer using div-form layout template."""


Now I call the URL.

http://localhost:8080/++skin++BlogSkin/Blog/2007_08_16_abc/EditEntry

2007_08_16_abc ist an BlogEntry object.

Now there comes an "ComponentLookupError. A server error occurred. " up.

Traceback (most recent call last):
  Module zope.publisher.publish, line 133, in publish
    result = publication.callObject(request, obj)
  Module zope.app.publication.zopepublication, line 167, in callObject
    return mapply(ob, request.getPositionalArguments(), request)
  Module zope.publisher.publish, line 108, in mapply
    return debug_call(obj, args)
   - __traceback_info__: <security proxied z3c.pagelet.zcml.EditEntry instance

  Module zope.publisher.publish, line 114, in debug_call
    return obj(*args)
  Module z3c.formui.layout, line 27, in __call__
    ILayoutTemplate)
  Module zope.component._api, line 103, in getMultiAdapter
    raise ComponentLookupError(objects, interface, name)
ComponentLookupError: ((<z3c.pagelet.zcml.EditEntry object at 0xa0248cc>,

URL=http://localhost:8080/++skin++BlogSkin/Blog/2007_08_16_abc/EditEntry.html>), 
<InterfaceClass z3c.template.interfaces.ILayoutTemplate>, u'')


I have also tried some variations of the above like not using z3c:pagelet but 
an normal page directive, registered it without an layer directive and so on.

So please... whats wrong there?

Thanks,

Florian
