roymcontentprovider/README.txt suggests that one can use a custom provider to do a 2-phased commit/render. This allows you to control the rendering order. Is it possible to have this and still somehow use a page template for the view?00:41
roymThe example shows uses a python render() method to generate the view.00:42

roymanyone out there?23:30
roymI need a little guidance on modifying contentprovider.23:30
roymBasically, I am trying to modify the provider: directive to not call update/render, but to simply return itself, so that I can control the calling of update/render from the zpt pages.23:32
roymIt seems like a lot of work, and I need to know if I am trying too hard.23:32
*** zbir` has quit IRC23:33
*** projekt01 has joined #zope3-dev23:33
roymroger: can I ask you a quick question about the contentprovider implementation.23:34
*** sashav has quit IRC23:35
*** mgedmin has quit IRC23:36
projekt01romy, yes sure23:37
roymI need a little guidance on modifying contentprovider.23:37
roymBasically, I am trying to modify the provider: directive to not call23:38
roymupdate/render, but to simply return itself, so that I can control the23:38
roymcalling of update/render from the zpt pages.23:38
roymIt seems like a lot of work, and I need to know if I am trying too hard.23:38
roymmaybe not modify the existing one, but create a contentprovider2 directive that does this.23:38
projekt01what about the nocall: prefix in tal?23:38
roymdoesn't seem to work. It still renders it.23:39
projekt01Ok. I see the return is:23:40
projekt01/* ---[ footer ]----------------------------------------------------------- */23:40
projekt01return provider.render()23:40
roymyes23:40
projekt01Why do you need this?23:40
roymI need to control update/render in viewletManagers23:40
roymfor exactly the reasons you outlined in your implementation.23:40
roymin TALESProviderImplementation23:41
roymsorry TALESProviderExpression23:41
projekt01I don't understand. What do you mean by the reason?23:42
projekt01What do you try to do in TAL whit the result?23:42
*** natea has quit IRC23:43
roymI have a case of two widgets (each in a different provider), and the rendering of each can only be correct after each has been updated.23:43
roymie: both updates need to happen first, then the renders.23:43
projekt01That's no problem23:44
roymhmmm, how would I handle that23:44
projekt01The provider TAL directives calls only the viewlet manager.23:44
projekt01The viewlet manager can collect all viewlets and update them, after that render them.23:44
projekt01We do this all the time similar in views based on formlib23:45
roymyes, but I have two different viewletManagers involved here.23:45
projekt01Uhhhhh23:45
roymfor layout reasons.23:45
projekt01That's another problem23:45
projekt01Let's see...23:45
roymyes, and in contentprovider/tales.py, srichter talks about this very thing23:45
projekt01There's a oprion to use global TAL variables in a viewlet manager. Did you see that?23:46
projekt01oprion/option23:46
roymno - can you point me23:46
*** kamalunch is now known as kamalgill23:46
projekt01See line 397 in zope/contentprovier/README.txt23:47
projekt01I guess this is the right concept to use.23:48
roymnot sure that I see how that lets me force 2 updates in a row, then 2 renders.23:49
projekt01Ok, there is no option to update two viewlets but you can use a global variable in both viewlet managers.23:50
projekt01Does this help?23:50
roymI'd have to think a bit about that. Is it reasonable to add a method to contentprovider that simply returns the provider23:51
projekt01Can you describe what a viewlet does after a update and why you can't rendere them before the second update?23:51
roymI have a folder of questions. Users select an answer and navigate to the next question.23:52
roymThe update happens to the current question. While rendering, the question id displayed needs to be that of the next question.23:53
roymPhysically however, (in layout) the qid is before the question itself.23:53
projekt01Smells like a use case for a session. or not?23:54
projekt01Or what about if you call define=""question provider:foobar" at the top of the page?23:55
roymI do use session data, if thats what you mean... I am using viewlets because the same question presents differently to instructors than students.23:55
projekt01and later you call replace="structure question"23:55
roymthat would probably work.23:56
roymHowever, doesn't that translate to 2 calls to the update/render pair.23:56
projekt01No, I use it also in some usecase wherer the order is relevant.23:57
roymsorry - you're right.23:57
*** RaFromBRC has joined #zope3-dev23:57
projekt01roym, let me know if this works or not. I fnot we have to find a way to sync two viewlet managers and update23:58
roymok - thanks for your help.23:58
projekt01the zope/contentprovider implementation.23:58
projekt01no problem23:58
roymIt would be nice to have a method that just returns the provider if tha's not too hairy.23:59
