a Grok 1.0 release plan

Martijn Faassen — 2008-11-28T16:08:29

Hi there, I think we should consider calling the next release of Grok Grok 1.0. I would like to put us through an alpha and beta phase however, for two reasons: * we have a number of potentially disruptive changes we'd like to get some feedback on before we release. * 1.0 pre-releases for 1.0 are good marketing. We should announce these loudly to get people to think about Grok. The bigger changes I'm aware of are: * new grokproject that uses paster and WSGI. This is done, but needs to be tested heavily. Existing documentation needs to be modified and we need 'best practices' documentation that describe how you'd actually use all the WSGI goodness in your application. This change is by far the biggest one to land in a 1.0 release. Opinions on how to manage this? * grokcore.viewlet extraction - the extraction is done but the core isn't modified yet, correct? Sylvain, what's the status of that work? * refactoring grokcore.view to support improved view inheritance. JW and I have been working on

Changing the name of a deployed application

rmoskal — 2008-11-26T22:52:37

I'm in the middle of deploying my first grok application to a production box. I've been letting the users work on another machine for the last few weeks, under a deployed app named "beta". I can move the app to the production box no problem, and the beta app is nicely deployed. But now I want to change the app to something likee "prod" or probably something more descriptive. Is there anyway I can change the name of a deployed app? Thanks and regards, Robert Moskal

Hi all, I am using zope. Wherein using some application i can create database ,then tables and i can enter the data into those tables.These transactions appear in mysql(when i see the databases). There is a gadfly folder in var in zope instance where some files are created corresponding the above database creation. What i want to do now is:- I already have some mysql database and i want to use it in the zope application(not like creating a database and then tables and so on like above.) How can this be achieved Any suggestions.

martian scan "bug" (feature?)

Chris McDonough — 2008-11-19T13:53:24

When martian scans packages (via the ModuleGrokker), eventually it winds up scanning modules that are defined via .pyc and .pyo file representations that do not have a corresponding .py source file. This, at least in my configuration, leads to errors because these are typically modules left over after, e.g. a module rename, where the "old" .pyc file sticks around even though its source file has changed names and has new content. I *think* what I'd like to do is change martian to (either unconditionally or optionally) skip modules that only have a .pyc or .pyo representation without a corresponding .py source. Below is a strategy to do so, if folks agree. One strategy to do so would be to use the "inspect.getsourcefile(module)" in places that try to use "dir(module)" to obtain a list of members of a module. For example, we might change ModuleGrokker's "grokkers" method to do: def grokkers(self, name, module): grokker = self._grokker # get any global grokkers for t in grokker.g

subdirectories of static do not usegc.v.component.DirectoryResource

Jan-Wijbrand Kolman — 2008-11-18T22:00:31

Hi, grokcore.view.component implements DirectoryResource and DirectoryResourceFactory classes, subclassing those from zope.app.publisher.browser.directoryresource for use in the "static" directory resource available in views. It does this for two reasons: 1) To override the security checker on the DirectoryResource instances and 2) to override the resource factories for *.pt and *.html files. However, the resource factory for *subdirectories* of the static directory is not overriden and thus for these subdirectories the z.a.p.b.directoryresource.DirectoryResource implementation is used. Fortunately, there's a recent release for zope.app.publisher that provides hooks for properly overriding these factories and with these hooks this bug is easily fixed. I'd like to update the version of zope.app.publisher in grokcore.view from the current 3.4.1 to the recently released 3.5.1 version to be able to checkin the fix. The tests for grokcore.view do pass with this version, but what possible implications sho

z3c.autoinclude hiding configuration conflict errors(?)

Jan-Wijbrand Kolman — 2008-11-18T16:18:16

Hi, Today I noticed something strange. z3c.autoinclude appears to swallow ConfigurationConflictError errors. Say I have a grok project (created with grokproject-0.9) called foobar. In the app.py that is created I add a skin definition like so: class ISomeLayer(grok.IBrowserRequest): grok.skin('foo') Then I create, again with grokproject, a project called qux. In the app.py modules of the qux project I also add a skin definition, *identical* to the one I added in foobar's app.py. Then I add foobar as a dependeny to qux, by way of qux's setup.py and develop directive in qux's buildout.cfg. Grokproject generated a configure.zcml for qux like so: The important part here is the directive that will make sure the configure.zcml of foobar is included and thus that foob

ImportError: No module named schemaless

Sven Dehmlow — 2008-11-16T20:35:42

Hi, I'm experiencing trouble while creating a new grok project. The error message is attached below. After googling a bit, I found a bug report for ubuntu (https://bugs.launchpad.net/zc.buildout/+bug/133462). The last advice in this report is to remove zope3 - however, I guess I need zope3 to run grok ... ;) Well, is there already a known fix for this issue? Thanks in advance Sven error message: sven< at >grisu:~/grok$ grokproject Sample Enter user (Name of an initial administrator user): grok Enter passwd (Password for the initial administrator user): Downloading info about versions...

Zope Objects Question

thorstenz — 2008-11-16T09:38:00

Hi. I am a bit confused in how to organise zope objects, so I can implement the following (and I hope somebody can help me with this): I have a kind of a poll. I want questions for this poll being editable (at any stage of the poll, even while it is running), therefore: Question(grok.Model), which I store in a Container, Questions(grok.Container) Then I want different containers where I select, which questions of the whole Question-Container are relevant for this container, I thought, this could be Poll(grok.Container) containing references to the Question-Container, I selected. And on the top of the Poll(grok.Container).QuestionReference(grok.Container???) I would like the answer: Choices(grok.Container) Again: Many Polls have many Questions within that Poll each of the many questions has many choices questions are always the same. If they change, they change in past, present and future polls. I don't know, how I can achieve this QuestionReference. Have you any clues? thx, thorsten.

problem with zope.app.testing during installation Grok on Windows XP

Roger Erens — 2008-11-12T22:54:53

I'm trying to install Grok on a freshly installed Windows XP Home system. When running the grokproject command, I get an error with zope.app.testing. Two others have reported this error to me as well. Any advice? IGetting distribution for 'zope.app.testing==3.4.3'.

Conflict between megrok.kss and megrok.form?

Douglas Cerna — 2008-11-07T20:43:21

Hi everybody. I've been trying KSS and I like it :) I started with the example in the "Adding AJAX to Grok with KSS" tutorial on grok.zope.org (http://grok.zope.org/documentation/how-to/adding-ajax-with-kss-to-grok) and it worked well. (I added megrok.kss to my setup.py and run buildout for this) But then I added features like dates and tried to use the zc.datetimewidget for my date fields. I know megrok.form gives this widget in an easy way. So I added megrok.form to my setup.py too and run buildout. And then my kss functionality stop working :( telling me: exceptions.TypeError: There isn't enough context to get URL information. This is probably due to a bug in setting up location information. I googled for an answer and the closest I got was: http://mail.zope.org/pipermail/grok-dev/2008-June/005744.html Then I tried to install only zc.datetimewidget the same way megrok.form does it (using directives in my configure.zcml), but I get an configuration conflict error when I include the zc.da

Problem with z3c.autoinclude of eggs in the Productsnamespace

Vincent Fretin — 2008-11-06T12:29:58

Hi, I have two eggs myproject.policy and Products.myproject. I use z3c.autoinclude in my plone buildout like this: [buildout] versions = versions eggs = [...] z3c.autoinclude myproject.policy develop = src/myproject.policy src/Products.myproject [versions] z3c.autoinclude == 0.2.2 [instance] zcml = z3c.autoinclude-meta myproject.policy If I put Products.myproject in eggs section. All works fine. But I don't want to put it in the buildout, but in setup.py of myproject.policy. In src/myproject.policy/myproject/policy/configure.zcml, I put: I want myproject.policy to depend of Products.myproject, so I put in install_requires=['Products.myproject'] in src/myproject.policy/setup.py I start the zope instance. The product myproject is shown and installable in Plone control panel. But doesn't appear in ZMI Control_Panel/Products, the result is that factories for the various types in myproject product are not created. I think z3c.autoinclude blocks th

Deploying into production - site.zcml with credentials

Ivo van der Wijk — 2008-11-06T09:30:50

Hi, My customer wants to deploy my grok application into production. I've provided a rather default buildout.cfg with a admin/admin username/password for a main manager account. Of course my customer wants to change this. However, as soon as I provide an update, any changes to buildout.cfg or site.zcml will be undone and the old 'admin/admin' u/p will be setup. I also can't provide a buildout.cfg without site.zcml credentials - you need them for the first time deployment. The only alternative option I can thing of is providing two buildouts, one with (for first time deployment) and one without site.zcml. How do you guys usually solve this problem? In the Zope2/Plone buildout world this is not an issue - there you only define a inituser which can be changed in the ZODB (acl_users) which buildout won't modify after updates. Regards Ivo

Default permission for Views?

Kevin Teague — 2008-11-05T01:04:37

I've got an app where I want to protect all Views be default to only users with a specific Role. There is this snippet generated by grokproject: But changing the site.zcml security declarations don't seem to effect anything. It seems like "grokcore.security.util.check_or_default_permission" is what decides the default permission with: if permission is None: permission = 'zope.Public' So should this be made overridable? Or should I just sprinkle grok.requires throughout my Views or am I missing something?

online shop done with Grok?

Toni Mueller — 2008-11-04T17:40:10

Hi, I'd like to have an online shop software package, preferably done with Grok. This is intended to replace, or be part of a replacement, for our current website, which runs on top of a package we'd like to phase out. I've so far seen Django's Satchmo which appears to fill most of my bill, but would prefer a Grok based solution w/o needing to re-invent the wheel. If you have pointers to share, I'm very interested! TIA! Kind regards, --Toni++

grok_overview.html: issue with adapters

Roger Erens — 2008-11-04T14:08:34

In the code example following 'We can now call sized for a content object and get an object back that implements the “sized API”:' we have currently: s = sized(my_content_object) print s.size() but size() is not defined in the code above. It seems to me that either the second line should read: print s.sized() But it looks silly to me to use 'sized' twice. So, in the code fragment above, the method definitions in the three classes would better be refactored from sized(self) to size(self)? Cheers, Roger
