hi there

Thanks for the reply. Removing the class attribute from the page directive got rid of the error. However I'm not overriding the VinePackage class.


class VinePackage(BTreeContainer):
        
        implements(IVinePackage)
        
        title = u""


Since it is inheriting from BTreeContainer, perhaps that overrides the constructor? I'll look into it and if I find an answer before someone else offers one I'll post it.

did you override the constructor in vine.vinePackage.VinePackage or one of its superclasses?

iv yes, then you need

def __init__(self,context,request):
    ...

as constructor, you can test it by just removing the class attribute of your page directive

hi there

I've got an error I've been stuck on for several hours now and I know the problem has got to be a very simple one but the error message I'm getting is not helping. I'm just trying to create a view for a very simple object. Here's the error I'm getting:

2006-04-27T13:58:09 ERROR SiteError http://localhost:8080/ VinePackage/@@details.html

    return factory(*objects)
TypeError: __init__() takes exactly 1 argument (3 given)

None of code I have written is in that trace so I have no idea where the problem is. Everything else I try to do with the object I'm trying to create a new view for works so I'm assuming the problem is in the ZCML for the view:

<page
        name="details.html"
        for="vine.interfaces.IVinePackage"
        class="vine.vinePackage.VinePackage"
        template="vinePackage.pt"
        permission="zope.Public"
        menu="zmi_views"
        title="Preview"
/>

The only other file I can think of that might be the cause of the problem is vinePackage.pt I took out all of the parts that refer to the Content Object in case the problem was there so I removed stuff until it was just a static html page and I was still getting the error. As far as I can tell I'm following the message board example in the Zope book pretty closely. If anyone has any suggestions on where I should look for the problem I would really appreciate it.

thanks
