[Repoze-dev] zope.schema, zope.formlib in bfg? or help a newb understand zca coolness
OK, not sure if this is a blasphemous question or not. I've been slowly
working through Web Component Development with Zope 3 , and instead of
trying out the things in zopeproject, I figured that trying out the things
in bfg as well may yield a greater understanding of what the heck is going
on. I realize that this may be incredibly dumb, so I'm not surprised that
I'm hitting roadblocks once in a while.
After reading up on zope.schema and zope.formlib, it seems that schema based
forms, fit my brain, and I would like to use them in bfg if possible rather
than tw.forms etc...
I got this far...
#models.py
#
...
class Record(Base):
__tablename__ = 'records'
id = Column(Integer, primary_key=True)
name = Column(Unicode(255), unique=True)
value = Column(Integer)
def __init__(self, name, value):
self.name = name
self.value = value
...
#views.py
#
...
from zope.interface import implements, Interface
from zope.schema import Text, Int
from zope.formlib.form import EditForm, Fields
class IRecord(Interface):
id = Int(
title = uThe id field,
description = ufield that holds the id,
required = True)
name = Text(
title = uThe name field,
description = uThe field that holds the name,
required = True)
value = Text(
title = uThe value field,
description = uThe field that holds the value,
required = True)
class RecordForm(EditForm):
form_fields = Fields(IRecord)
label = uEdit Record
...
#configure.zcml
#
...
view
for=.models.Record
view=.views.RecordForm
name=edit.html/
...
First run and accessing the page http://localhost:6543/1/edit.html I get an
expected error...
TypeError: ('Could not adapt', tst.models.Record object at 0x9fb0d4c,
InterfaceClass tst.views.IRecord)
Makes sense, I need to create an adapter, no biggie.
#views.py
#=
class RecordAdapter(object):
probably not the best way to do this...
def __init__(self, context):
self.context = context
def _get_id(self): return self.context.id
def _get_name(self): return self.context.name
def _get_value(self): return self.context.value
def _set_id(self,v): self.context.id = v
def _set_name(self,v): self.context.name = v
def _set_value(self,v): self.context.value = v
id = property(_get_id, _set_id)
name = property(_get_name, _set_name)
value = property(_get_value, _set_value)
...
and registered
#configure.zcml
#
...
adapter
factory=.views.RecordAdapter
provides=.views.IRecord
for=.models.Record/
...
Next run fingers crossed.
ComponentLookupError: ((zope.schema._bootstrapfields.Int object at
0xa690c6c, Request at 0xa69084c GET http://localhost:6543/1/edit.html),
InterfaceClass zope.app.form.interfaces.IInputWidget, u'')
Based on my limited understanding of zope, I am assuming that in my
configure.zcml I need to include a package, maybe zope.app.form ?
#configure.zcml
#
...
include package=repoze.bfg.includes/
include package=zope.app.form/
...
next run results in not even getting the server running.
zope.configuration.xmlconfig.ZopeXMLConfigurationError: File
/home/twillis/projects/bfg/tst/tst/configure.zcml, line 5.2-5.36
IOError: [Errno 2] No such file or directory:
'/home/twillis/projects/bfg/lib/python2.6/site-packages/zope.app.form-3.8.1-py2.6.egg/zope/app/form/configure.zcml'
and indeed it doesn't exist. So all of this was done in a virtualenv and
easy_install. So finally here's my questions.
#1 does bfg provide machinery for registering components or is that
functionality specific to big daddy zope? I assume the answer is yes,
augmented with it depends. I realize that bfg is meant to isolate you
from the zca, but darn it I think it's cool and I want to understand how
it's used. The above referenced book doesn't have any obvious section that
details how this works, at least not that I've found, so if anyone knows of
an online resource on how this works. I'd appreciate knowing about it.
#2 is the fact that an easy_install off zope.formlib results in no out of
the box zcml file to include (as far as I can tell) a result of these
particular zope libs not being refactored to be more standalone-ish? If so,
what would generally be the process of making it more standalone-ish. Would
it just be coming up with some configure.zcml to deploy with the package?
Hell If I knew all this already, I'd blog it. Because I'm sure there are
others out there interested in zope/repoze and might get intimidated by this
kind of thing. :)
Anyway, thanks for reading, any information is appreciated.

Re: [Repoze-dev] zope.schema, zope.formlib in bfg? or help a newb understand zca coolness
I actually looked at this yesterday and it didn't seem to generate forms but does provide the marshaling + validation. so it seems to me it's similar to formencode/htmlfill, where I'm looking for something more like tw.forms.

I think that would go a long way to increasing bfg adoption. BFG's roll-you-own nature makes great docs even more important and I think Chris et al have done a fantastic job in that regard, but I gotta admin I hit the wall when it came to repoze.who/what. The system is great, but there is a *lot* to digest to get it working. Iain Yes with bfg. for example http://docs.repoze.org/bfg/1.1/narr/security.html#repozewho1authenticationpolicy gives the details for setting up a repoze.who authenticationpolicy (though I think I could use the remote user one too) but repozewho1authenticationpolicy identifier_name=auth_tkt callback=.somemodule.somefunc / but the callback arg doesn't make sense if you already have a GroupSource and PermissionSource configured via repoze.what. But not putting a callback in makes the policy assume the user belongs to no groups. I think repoze.what ties permissions to groups, so if user belongs to no groups then no permissions? Furthermore, I don't have a callback to put there, it's all config driven. As far as I could tell, repoze.what doesn't seem to provide a way to get at the groups for the current request, but I could be wrong here. But even if I could get the groups back, how would I wire in the PermissionSource for acls? I still feel like I'm missing something obvious. But I was hoping to get this working because I rather like having the perms configured in the zcml rather than in decorators/predicates on specific functions. Other than that, thank you to those responsible for bfg. I'm really digging it despite these little hurdles. -- Thomas G.
