Forum OpenACS Development: CR's rendering features
The first thing I need to know is if anyone's using this stuff, so that I can avoid breaking things that are being used, and so that I can learn how to use it properly, so I can possibly avoid making changes in the first place.
I have two conten items. One is an image, stored in the file system.
The other is a content item with text/html content. It has the image as a related item (cr_item_rels) with relation_tag "image". Its contents contain this tag:
<relation tag="image" index="1" embed>
What I want is for this tag to be replaced with <img src="path-to-image-in-the-file-system' ...>
I've managed to get it to work as expepcted, but only by hacking publish-procs.tcl a bit.
The problem is that the publish::handle_binary_file proc called by publish::handle::image tried to merge the image with a template unless you specify -no_merge. Unfortunately, I can't find any right way to pass this switch to it.
The question is: Does anybody know how it's supposed to work?
There's all this code that handles merging the binary image file with a template, so I'm assuming that there's some thought behind it. But what should the template for merging with the image look like?
On the other hand, publish::handle::image also has code to spit out the <img ...> tag when handle_binary_file does not merge with a template. So there ought to be some way to tell it not to, yet I cannot find it.
My hack that works is to simply add the -no_merge switch to the call to handle_binary_file inside publish::handle::image. But that obviously precludes using a template.
Any complaints if I mock with this? Nobody's using this, right?
I don't think anybody is, because some required procs were missing from acs-content-repository/tcl/cpublish-procs.tcl that were present in cms/tcl/publish-procs.tcl, so things didn't work.
Thanks for your help.
Not aware of anyone using it. I had a hard time trying to understand it, so I am just using normal templating system. The way I dealed with the related images. I that I had a related-images file which was included on the template that rendered the content.
Hope you make it run and see how it goes.
Are you using the content-repository features alone? Did you check into how the CMS package uses this feature?
Also, the documentation doesn't offer any useful help.
Do you know of a place where I should look?
