Hey Bruce,

First off, I am new to Ruby, Rails, and Radiant (bout 2 months of  
studying  
now) but they are totally mind-blowing heh (So correct me where I say  
totally wrong things). Next, I actually just started work on adding  
commenting abilities to Radiant. My thoughts are a behavior is not the  
best  
way to go because one will potentially want to add the ability to  
comment on  
a page that already has a behavior (I am guessing in most cases the  
behavior  
will be some sort of blog behavior). My next thoughts were to implement  
the  
extension as a Rails plugin. However, I am having a lot of trouble  
finding  
information on the best way to extend a model via a plugin (lots of  
people  
run into issues where thier enhancements get dropped when the model gets  
reloaded in a dev environment) and it also seems like testing models in  
plugins is a big pain (like I said I’m a noob so the two afformentioned  
things might just be necessary hurdles). In an effort to just get  
something  
working I went ahead and added a bunch of stuff right into Radiant,  
figuring  
I could pull it out into a plugin later if I solved the above problems.  
I  
added a Remark class to the model (I tried to create a comment model but  
the  
generator yeleld at me and said “comment” is a reserved rails word so  
remark  
== comment from here on out) that belongs\_to page. I added has\_many  
remarks  
to the Page model. I added the following tags right into page\_context  
(that’s right I held no reservations about mucking up the innards of  
Radiant  
heh): remark, remark:each, remark:author, remark:content, remark:form  
remark:form is interesting as it generates a form for creating a new  
comment…In order for this to work I had to modify the process method  
in  
Behavior with something like:  
if request.post? etc etc else the normal process. This is bad because  
any  
behavior that processes a form and uses if request.post? to check for  
form  
submission will break (i.e. the mailer behavior Matt Mccray posted on  
this  
list). All in all I just kinda dove in…but hopefully I exposed some  
potential problems re: comments. Thoughts? I’d appriciate any  
direction/help/abuse 😛

Thanks!  
Justin
