Plone middle aligns all colums
by Lars Hohmuth 17 Jan '08

17 Jan '08

I have a weird problem with our Plone 2.5.3 test site after a new designer took over. Plone now middle aligns the content column and the portlets in the slot on the center line, instead of on top. -------------------- --------------------------- | Left-slots | | | center | | --------------------------- --------------------- We can sort of fix this by manually adding vertical-align: top; in the css. But my designer claims that he caused this by "changing a setting in Plone or the ZMI" and doesn't remember which one. Since it's not on the production site, it's not a life and death situation, but any suggestions what might cause this are gratefully accepted. Google and the Plone site search yielded pretty much nothing. Thanks, Lars Hohmuth

Zope ZMI Templates
by Jurian Botha 17 Jan '08

17 Jan '08

I'm currently developing some customized ZMI pages and I was hoping someone could give me some insight into what the best way would be to do this. I see that Zope 2 uses dtml methods to build the standard ZMI pages but as far as I know (Zope 3 wise) I should rather be using Zope Page Templates to build the pages. I would also like the product to gracefully move on to Zope 3 in future, so that should be taken into consideration as well. Are there perhaps some existsing templates for ZMI that can also be used with Zope 3? -- View this message in context: http://www.nabble.com/Zope-ZMI-Templates-tp14734109p14734109.html Sent from the Zope - General mailing list archive at Nabble.com.

lambda's in external methods
by David Bear 16 Jan '08

16 Jan '08

In the zope 2.7 book it mentions that an optimization technique for external methods is to compile regular expressions in global scope to the module. The re's will then be compiled at zope load time. I am wondering if the same holds for lambdas. I created some simple filters using lambdas. I defined them in the functions where I use them. Is there any advantage to defining them globally to the module? Are there any gottcha's with globally scope objects? -- David Bear phone: 602-496-0424 fax: 602-496-0955 College of Public Programs/ASU University Center Rm 622 411 N Central Phoenix, AZ 85007-0685 "Beware the IP portfolio, everyone will be suspect of trespassing"

NamedTemplate.__call__ not returning anything
by Maurits van Rees 14 Jan '08

14 Jan '08

Hi, I have some code where I try to get a named template and render it and if it fails I render a default template instead. But this fails, presumably because the __call__ method of NamedTemplate does not return anything. From zope/formlib/namedtemplate.py (Zope 2.10): class NamedTemplate(object): def __init__(self, name): self.__name__ = name def __get__(self, instance, type=None): if instance is None: return self return component.getAdapter(instance, INamedTemplate, self.__name__) def __call__(self, instance, *args, **kw): self.__get__(instance)(*args, **kw) I seems strange to me that __call__ does not actually return anything. Is it just me? Now, I have some other code where NamedTemplate is working just fine, so there is probably nothing wrong with this __call__ method. So can anybody tell me what is wrong with my following code then? class Renderer(base.Renderer): default_template = ViewPageTemplateFile('vocabularyportlet.pt') def render(self): """Render a named template or the default template. """ template = NamedTemplate("test.vocabulary") try: output = template(self) except ComponentLookupError: output = None # Even if the component lookup works, output can be None. if output is None: output = self.default_template() return output The line "output = template(self)" fails with a ComponentLookupError unless a named template with the name test.vocabulary exists. But when that template is found, output is still None. In case you want to see the entire code, this is in a Plone portlet that I am developing: http://svn.plone.org/svn/collective/collective.portlet.vocabulary/trunk/col… And actually, the tests that I added pass when I change the NamedTemplate.__call__ method to return the value that it just got. So should that method be changed or is there a different way to do this?

Problem with buildout
by Alex Turner 14 Jan '08

14 Jan '08

I am building a plone3 site using buildout, but I've noticed that the scripts in <path>/parts/zope2/utilities and <path>/parts/zope2/ZODBTools have a different interpreter. So much so that the scripts in ZODBTools don't work on my system because they are trying to use a python that doesn't exist. Alex

The best way
by Garito 14 Jan '08

14 Jan '08

Hi, all! If you have download the ZSM product you could see I put on it a zexp file with prototype and some other js file and a css file plus images This was only a prototype solution to bring you the chance to see how my ideas are but I think this is not a definitive solution Now my question: Which is the best zope way to serve this kind of files trying to avoid any other product dependence? Thanks a lot! -- Mis Cosas http://blogs.sistes.net/Garito

manage_renameObjects and AJAX
by Garito 13 Jan '08

13 Jan '08

Hi! I'm try to implement the edition part of ZSM and I begin with the rename objects functionality I create a InPlaceEditor object to rename every branch but when I submit the form the rename command works ok but the response is the manage_main (or similar) and the tree disappear Is there a way to make manage_renameObjects returns the changed values? If not I need to write another monkey_patched function, isn't it? Thanks! -- Mis Cosas http://blogs.sistes.net/Garito Zope Smart Manager http://blogs.sistes.net/Garito/670

"can't pickle instancemethod objects" in testcase

My code works fine in normal running zope but not when run as a testcase (I'm not using bin/zopectl test if that matters) I get the following error.

Re: [Zope] The best way

Hi! Thanks Martijn and Matt for your ideas! @Matt: can you explain with more detail the question about REQUEST.response.write()? If the written content is as long as a file like prototype is not a very heavy solution? The contents of the zexp file are only js files and images (static content) and I'm using Zope2 What about the functionality of the freemind view? What do you think about?
