If I create a macro which defines a slot called 'content', is there any way to have that slot populated by a file with a specific name if it exists in a folder? What I'd like to do is create a structure text file, in each of the folders A B C and have it automatically loaded into a content slot of a master template whenever the options A B C are selected.

Can I do that, and if so how?

I have spent all day looking at ZPT references and have no idea if what I'd like to do is possible.


You don't have to involve macros::

 <div>I'm a header</div>

 <p tal:condition="exists:context/stxfile"
    tal:replace="structure context/stxfile/CookedBody">
   This is sample page content
 </p>

 <div>I'm a footer</div>

If 'stxfile' can be aquired, what it renders will be included as page structure. (You may need to use a different method one the end of the path to render the object; for Documents, this is 'CookedBody'.) Otherwise, nothing will be rendered, though you could add a block with the oposite condition to supply a default action.



Is 'stxfile' the actual filename? I'm not concerned about it being structured initially - just want to see it working in principle with any file containg some text.


It's the name of an object. I made up this name for your "structure text
file, in each of the folders A B C". You may call it as you will.

Note: there is no such thing as a "file" in the ZODB. Everything is an
object.

This is how "content" is viewed. One thing I forgot to mention: you
would apply this template (say it's named 'special_view') to your
folders, like:

http://localhost/A/special_view
http://localhost/B/special_view
http://localhost/C/special_view

Now, if we used a template like this (let's name it 'direct_view')::

  <div>I'm a header</div>

  <p tal:replace="structure context/CookedBody">
    This is sample page content
  </p>

  <div>I'm a footer</div>

we could apply it like so::

http://localhost/A/stxfile/direct_view
http://localhost/B/stxfile/direct_view
http://localhost/C/stxfile/direct_view

This is a much more typical pattern, at least for content. If you want
to apply a wrapper to page templates, then you use macros.
