[Grok-dev] Help with z3c.form and zope.file

[Danilo G B]

Hey guys, please help me! I'm using Grok 1.4, z3c.form 2.4.2 and need a field to 
hold an uploaded file. I would like to have something as close as possible to 
plone.formwidget.namedfile. Whether I depend on z3c.namedfile, zope.app.file or 
zope.file the result is ultimately the same: complains about dependencies that 
goes down to the point where I can't go further, i.e, 


    ConfigurationError: ('Invalid value for', 'menu', "ImportError: Couldn't 
import zmi_actions, No module named zmi_actions")

The (simplified) code is as follows:

from zope.interface import Interface
from zope import schema
import grok
from zope.schema.fieldproperty import FieldProperty
from megrok.z3cform.base import PageAddForm, Fields


class IDocMaster(Interface):
    title = schema.Text(title=u"The title")
    template = schema.Bytes(title=u"The template")

class DocMaster(grok.Model):
    grok.implements(IDocMaster)

    title = FieldProperty(IDocMaster["title"])
    template= FieldProperty(IDocMaster["template"])

    def __init__(self, title, template):
        self.title = title
        self.template = template

class DocAdd(PageAddForm):
    grok.context(Interface) #actually a specialised container
    
    fields = Fields(IDocMaster)
    label = "New doc"
    
    def createAndAdd(self, data):
        doc = DocMaster(**data)
        id = str(doc.title) #if you use a single word as title this will do
        self.context[id] = doc

In setup.py,

install_requires=[
          'setuptools',
          # -*- Extra requirements: -*-
          'zope.browserresource',
          'zope.app.pagetemplate',
          'z3c.form',
          'megrok.z3cform.base',
          'megrok.z3cform.ui',
          'megrok.z3cform.layout',
          'zope.app.schema',
          'zc.sourcefactory',
          'relatorio',
          #IF I INCLUDE THESE THE ABOVE MENTIONED ERROR OCCURS
          'zope.browsermenu',
          'zope.app.container',
          'zope.file',
          'zope.mimetype',
      ],
