Re: [Zope3-Users] Arranging widgets in a form / Limit size of input fields
One way would be to create a custom template file, where each widget is placed via HTML. However, this is quite some work. I've often done this and it doesn't seem like too much work. But I don't dispute your evaluation. I've used my own templates as well. It is more work than having autogenerated form but it is not so hard. In fact you may change template to use divs instead of tables and then play with css only to arrange your forms. My approach is different to Fred's because I rarely call setUpWidgets in my form code.

AFAIK for textarea html fields you can't set something like maxlength. You have to use javascript for that. -- Maciej Wisniowski ___ Zope3-users mailing list Zope3-users@zope.org http://mail.zope.org/mailman/listinfo/zope3-users

Re: [Zope3-Users] Arranging widgets in a form / Limit size of input fields
In my case, I have several forms with e.g. 10-15 fields, so this adds up and
in the end the templates are quite complex. If there were some shortcut or
macro which generates the above HTML-code, it would be a lot easier, perhaps
there's a decent solution? If it would looke something like this, it would be
much easier to manage:
span tal:content=view/widgets/foo/gen_html /
Isn't tal:repeat enough?? Something like:
tal:block tal:repeat=widget view/widgets
div class=label
label for=field.name title=The widget's hint
tal:attributes=for widget; title widget/hint
tal:content=widget/labelLabel/label
/div
div tal:condition=widget/error
tal:content=structure widget/errorError/div
div class=field
input tal:replace=structure widget /
/div
/tal:block
If you need specific widgets order then you may use:
form.FormFields(interfaces.ISomeInterface).select('field1', 'field2',)
Another possibility io define function in your view class like:
widgetTempl = ViewPageTemplateFile('widgetsection.pt')
def genWidgetHtml(self, widget):
return self.widgetTempl(widget=widget)
and create file widgetsection.pt with content like:
tal:block tal:define=widget python: options.get('widget', None)
div class=label
label for=field.name title=The widget's hint
tal:attributes=for widget; title widget/hint
tal:content=widget/labelLabel/label
/div
div tal:condition=widget/error
tal:content=structure widget/errorError/div
div class=field
input tal:replace=structure widget /
/div
/tal:block
Then in your pageform.pt just call for every widget something like:
div tal:replace=python: view.getWidgetHtml(view.widgets['foo'] /
Above code is from head so may be buggy or incomplete.

Hi Hermann,
I started a form layout add-on for formlib, see snippet below..
It's a very rudimentary first cut, and only provides a grid (table)
layout. I can't see myself getting any time to work on it in the
immediate future. If you think it might be useful I can send you the
package (which includes doctests).
Regards

[Zope3-Users] Ch 7, lookup error in getMultiAdapter
Working through Web Component Development with Zope 3 Second Edition, I'm
stuck just at the point it gets more interesting.
In the interactive debug session looking at a basic view, I get a lookup
error at...
view = getMultiAdapter((lasagne, request), name=u'index.html')
I've confirmed that both lasagne, and request are objects.
the error reads in part, line 103 in multiadapter ...
zope.component.interfaces.ComponentLookupError...
And related to this, when I open the browser to the recipes stored in root
http://localhost:8080/minestrone
as the example shows, I get The page that your are trying to access is not
available, even though ministrone is in the root and shows up in the ZMI
I need help getting further in my studies. If there is a FAQ or archive if
this list please let me know where it is.
