zope.app.file/zope.file buildout error

Mauro Boschi — 2012-05-22T15:48:54

Hi,
I've tried to run Music Tutorial but it doesn't work in song.py section ( http://grok.zope.org/documentation/tutorial/musical-performance-organizer-part-1 ). So I've tried zope.file how-to: http://grok.zope.org/documentation/how-to/uploading-file but it doesn't work too! :(

with a new grokproject test

I've added in buildout.cfg:
[zope_conf]
recipe = collective.recipe.template
input = etc/zope.conf.in
output = ${buildout:parts-directory}/etc/zope.conf
filestorage = ${buildout:directory}/var/filestorage
blobstorage = ${buildout:directory}/var/blobstorage
devmode = on
extra =

#I've added the devmode line to resolve another error.

Then I've added in setup.py:
      install_requires=['setuptools',
                        'grok',
                        'grokui.admin',
                        'fanstatic',
                        'zope.fanstatic',
                        'grokcore.chameleon',
                        'grokcore.startup',
                        # Add extra requirements here

Pickle namespace clash

Alex Leach — 2012-05-21T12:50:52

Dear Grok Devs,

I've got Grok set up on a number of machines, and have started getting some
errors on my Mac OS X Lion machine
I had Grok set up nicely using mod_wsgi and the Enthought Python
Distribution, so that I could take advantage of Enthought's MKL libraries
with numpy, but a recent buildout has somehow killed it.

The end of the paster error is below.

pickling of dynamic classes

Anurag Sharma — 2012-05-16T11:24:30

Dear All,

This seems to be generally a problem with pickle but I hope I will be able
to get some inputs for the problem.

In one function of my grok.Application class I'm dynamically creating a
class

self.VarName = type('class name', (<base class>,), dict())
* <base class> does inherit grok.Container.*

While running this I'm getting following error:

Module ZODB.serialize:*422* in serialize
<http://localhost:8080/bizopine#>
__getstate__*(**)**)*
Module ZODB.serialize:*431* in _dump        <http://localhost:8080/bizopine#>
*PicklingError: Can't pickle <class '<appname>.app.<class name>'>:
attribute lookup **<appname>.app.<class name>** failed*

Pickling documentation does say that :
What can be pickled and unpickledclasses that are defined at the top level
of a module

*But is it the problem here and if yes then what can be the possible
solution for this ?*

Thanks,
Anurag

grokcore.resource

Jan-Jaap Driessen — 2012-05-14T19:02:27

After the recent grok sprint I have spent some hours taking parts of
megrok.resource and putting them in the grokcore.resource package:

svn+ssh://svn.zope.org/repos/main/grokcore.resource/trunk

grokcore.resource helps you use fanstatic resources in your view
components. Instead of `needing` resources in the update method of
your view components, you can use a directive to associate resources
with a view component, so instead of::

class MyView(grok.View):
    def update(self):
        myresource.need()

You write::

class MyView(grok.View):
    grok.resources(myresource)

This removes a lot of one-line update methods from our code base,
which is good. grokcore.resource works for grok.View, grok.Viewlet,
grok.Layout and grok.ContentProvider view components.

Are you ok with making this a part of grok? I created a branch of grok
in which I incorporated grokcore.resource:

svn+ssh://svn.zope.org/repos/main/grok/branches/janjaapdriessen-grokcore-resource

I would like you to try this out in your own applicatio

Static dir with grok.PageTemplateFile

Alex Leach — 2012-05-13T18:05:46

I have a few forms in separate modules that share the same template. Rather 
than having the template in the <module_name>_templates/ directory, I've got 
this one 'edit-form.pt' template in the bottom, src/ directory.

It worked fine, until I added a (conditional) include in the head of the page 
template, so that it downloads a CSS stylesheet if the form request wasn't 
done through an AJAX call.

So I'm getting an error now, whenever I request one of the forms which use 
this template, as it fails to find the static directory holding the CSS. I've 
tried adding `resource.style.need()` to the forms' update methods, but they 
still don't find the static directory. Part of the traceback shows this:-

Line 5, Column 10
In expression: <PathExpr standard:u'static/css/style.css'>

   - Names:
      {'args': (),
       'context': <server.app.Server object at 0x7f4878033668>,
       'default': <object object at 0x7f4891c0a490>,
       'loop': {},
       'nothing': None,
       'options': {},
       'repeat': {},

megrok.rdb setup error

Mauro Boschi — 2012-05-10T16:26:53

Hi to all,
I'm new with Grok!

As in http://grok.zope.org/documentation/how-to/orm-using-megrok.rdb-and-sqlalchemy

I have added megrok.rdb to setup.py

install_requires=['setuptools',
          ...
          # Add extra requirements here
          'megrok.rdb'
          ],

than run bin/buildout

restarting Grok I see this error:

PageTemplateFile('path/to/template.cpt') does not workanymore

Jan-Wijbrand Kolman — 2012-05-07T09:38:19

Hi,

With the new release of grokcore.chameleon it seem the following pattern
does not work anymore:


from grokcore.chameleon.components import PageTemplateFile

class MyView(grok.View):
  template = PageTemplateFile('templates/mytemplate.cpt')
  ....

I guess this is because the template baseclasses in z3c.pt are not used
anymore as such in grokcore.chameleon?

Anyone an idea? I'll look into it as well now...

grokcore.security

Souheil CHELFOUH — 2012-05-06T21:43:23

Hello all !

it seems that grokcore.security doesn't declare its dependency on
zope.dottedname, needed for :

def api(name):
    from zope.dottedname.resolve import resolve
    from zope.interface import Interface

    try:
        return True, resolve(name)
    except ImportError:
        return False, Interface


Can anyone with release rights fix this ?
Thank you !

grokcore.resource

Jan-Jaap Driessen — 2012-05-01T08:42:56

In the train back home from the grok sprint yesterday I took some
parts of megrok.resource [1] to combine with fanstatic [2] into
grokcore.resource [3].

With grokcore.resource you can make resources part of your View classes like so:

"""
class MyView(grok.View):
    grokcore.resource.include(css_a, css_b)
"""

This is a handsome replacement of the "old" way of declaring resource,
often in the update method of the view:

"""
    def update(self):
        css_a.need()
        css_b.need()
"""

(This "old" way is still supported.)

The "include" directive code looks like this:

"""
class include(martian.Directive):
    scope = martian.CLASS
    store = martian.MULTIPLE
    validate = validateInclusion

    def factory(self, *resources):
        zope.interface.declarations.addClassAdvisor(
            _resources_advice, depth=3)
        return resources

def _resources_advice(cls):
    if include.bind().get(cls):
        if not grokcore.resource.interfaces.IResourcesIncluder.implementedBy(
                cls)

i18n translation weirdness

Noe Nieto — 2012-04-27T17:23:24

We have a couple of grok.Forms where we change the title of some widgets in
the setUpWidgets() callback:

    def setUpWidgets(self, ignore_request=False):
        super(AddProjectForm, self).setUpWidgets(ignore_request)
        self.widgets['city'].label = '1'
        self.widgets['specialty'].label = '2'
        self.widgets['contractor'].label = '2'

        self.widgets['city'].title = _(u'City?')
        self.widgets['specialty'].title = _(u'What you need to do?')
        self.widgets['contractor'].title = _(u'Who you want for you job?')

The problem with this is that, while our translatable strings are
recognized as translations and we have proper translation strings in our
.po files, these strings are never translated.

So, what's the catch?

zope.keyreference.interfaces.NotYet is thrown whilerunning tests

Noe Nieto — 2012-04-25T05:17:25

Hi,

I have a package homeviva.testing that holds all tests from our aplication.
Inside that package I added a subclass of
zope.app.wsgi.testlayer.BrowserLayer that will add an instance of our grok
application add then add some more dummy data as a way to provide a common
test fixture to all of our integration test.

The layer looks like this:

from zope.app.wsgi.testlayer import BrowserLayer

class HomeVivaIntegrationLayer(BrowserLayer):
    """
    Integration Layer for HomeViva.
    """
    consworks_app = None

    def testSetUp(self):
        super(HomeVivaIntegrationLayer, self).testSetUp()

        #Add test app
        from consworks.app import Consworks
        zodb_root = self.getRootFolder()
        zodb_root['app'] = self.consworks_app = Consworks()

        #Fire up events
        import grok
        grok.notify(grok.ApplicationInitializedEvent(self.consworks_app))

        #... more stuff here

When I run my tests individually all goes fine, but if I try to run all the
tests within the package,

Selenium Tester

Maximiliano Pallotto — 2012-04-20T21:31:20

Hi guys!

We're currently needing an extra hand with testing for
HomeViva<http://www.startupchile.org/supprojects/homeviva>

If you have some spare time and lots of expertise on selenium for zope to
create black box tests for our app, you're invited to join our awesome
team. Also knowledge about Grok is preferred since we'll need unity testing
afterwards.

So, anyone there willing to accept the challenge?

Best,
Max

Use grok/zope i18 translation mechanisms in external nongrok/zope application

Hector Blanco — 2012-04-13T16:41:24

Hello everyone.

I have a web server (called "my_server", of class
"my_server.app.My_server") that is properly using the i18 translation
features implemented in Grok. I followed this guide:
http://grok.zope.org/documentation/how-to/how-to-internationalize-your-application
and the translations are working very well when "inside" the server.

Now, I have another Python application that is non-related to this
Grok/Zope server (it just uses its ZoDB for persistence and as a
"common storage" area) which could actually benefit from the
translation infrastructure provided by Grok/Zope.

Is there any way of accessing my server's translations from an
external application? Said external application is executed via an
script generated as an "entry point" of the "my_server" package. I can
actually invoke the script with "my_server/bin/myStartupScript" so at
least the paths used for the "my_server" application, like
$HOME/.buildout/ and all that should be available (thanks to Kevin
Teague for the hint he gave me on that

Testing and events

Noe Nieto — 2012-04-11T02:01:31

I'm doing integration testing and my app has an event subscription to
grok.IApplicationInitializedEvent.

When setting up my layer I'm doing the following (layer is
zope.fanstatic.testing.ZopeFanstaticBrowserLayer):

    def setUp(self):
        #Add test app
        from consworks.app import Consworks
        import grok
        self.root = self.layer.getRootFolder()
        self.root['app'] = Consworks()
        grok.notify(grok.IApplicationInitializedEvent)


But the handler for IApplicationInitializedEvent is not being called. What
else do I need to do to make it work?

grokcore.component.util.sort_components

Sylvain Viollon — 2012-03-28T13:12:59

Hello,

    I would like to add an option key, that explain to sort_components how to get the component in the list of items to sort.

    Basically, it is composed with the exiting key sort function.

    What do you think of this ?

Pluggable Grok API

Sylvain Viollon — 2012-03-26T12:05:23

Hello,

   We were talking since a while to have a way to automatically import things in the grok top-level package if other packages are present.

   I would really like to see this coming through.

   We could use the interfaces IGrok..API defined, that are used to define __all__ in the __init__ of each package, as entry-point values in setuptools. After we could write a piece of code that does the import based on that, in a package, if the name is not already defined (so we can still override things, like View in grok). That could be doable.

   What do you think of this idea ?

   Regards,

     Sylvain,


PS: And we coud throw away formlib !

Conditional grokking

Sylvain Viollon — 2012-03-26T12:01:24

Hello,

  I would like to add a feature in martian, that would let you grok a package only if a condition is met.

  My idea is still vague, but I would to make possible not to grok a package (or module) if an another package is not present (a bit like zcml:condition="installed package").

  This could be done by triggering an exception that martian catches  and skip the package (of course you will have to use this at the top of your file).

  What do you think of this silly idea ?

  Regards,

   Sylvain,

module_info, template, grokcore.view

Sylvain Viollon — 2012-03-26T11:56:13

Hello,

   I still use the view.static behavior, with grokcore.view. I don't know if you do guys.

   I am often annoyed by one point however. I mostly (95% or the time) use the view.static in a template. However if I inherit my view in an another package, I keep my template, but the view.static is different, and I loose access to the resources.

   For me, static is linked to the template. I think it should be 'kept'.

   For the moment static is an adapter that is queried with the name of the package that contains the view. I propose to change this to the name of the package that contains the template.

   I poposed to add an attribute __static_name__ (or something else) on the view, that would be initialized by the template registry (in templatereg, associate_template) with the value of the module_info.package_dotted_name if there is an association.

   In the view base class, the static adapter would be looked using this name if set, or will default to the one contained in the view's module_info.
