That is a very good point you bring up. The fact that maintenance or additions
in terms of page templates will probably be done by someone else.
However i fee although there some learning curve associated with this particular
option, it is not unsurmountable. In any case our current site uses quite a bit
of cfmodules for content pods, so there is an extra leve of abstraction that
already exist.
What i am trying to achieve in terms of layout code would be something like the
following:
cfset newLayout = createObject('component', 'model.layout_twoColumn')
cfset menuBar = createObject('component', 'model.layout_mnuBar')
cfset list = createObject('component', 'model.HTMLObject_ul'
cfset list.configure( content, "class=homepage" )
cfset paragraph = createObject('component', 'model.HTMLObject_p
cfset paragraph.configure( content, "class=homepage" )
newLayout.leftColumn.add( menuBar )
newLayout.rightColumn.add( list )
newLayout.rightColumn.add( paragraph )
newLayout.render()
newLayout.render() would return the entire layout in a string variable back to
the request scope and to a cfm container page (which would be empty).
That way as new html blocks or content area are created , we could either extend
existing class or create new ones to accomodate. We can then catalog all our
little widgets.
Cascading changes through our sites would therefore a lot easier, then if the
formating code was contained on cfm pages even if they were themselves templates.
Am i trying too hard to stick everything in the OO box?
