[Grok-dev] Re: absolute url for 'static' ?

[Sebastian Ware]

I solved it by adding the storage utility... this is basically the  
code if someone is stuck with the same problem. I will try to write a  
howto soon.

from z3c.blobfile.file import File
from z3c.blobfile.storages import StringStorable

class AddMyFile(grok.AddForm):
     title = 'Add file'
     form_fields = grok.AutoFields(File)

     @grok.action('Add')
     def action(self, **data):
         site = grok.getSite()
         file = File()
         self.applyData(file, **data)
         site["file_%s" % len(site.keys())] = file

class MyFileStorageUtility(grok.GlobalUtility, StringStorable):
     grok.name('__builtin__.str')
