DRY Scaffolds

Rails
#1

I’ve got 8 scaffolds, each one can be considered an ‘item’, such as a
blog, photo, etc. Using login_engine and user_engine, I list all blogs
belonging to a user by saying:

@user=session[:user]
@[email protected](:all)

but then let’s say I want to create an option where I want to slice it
differently:

@user=session[:user]
if @someOption ==1
@[email protected](:all)
else
@[email protected](:all, :conditions=>[“time=?”,@timeOfDay])
end

Having done that, now I’d like to use it in all 8 scaffolds. Right now
I’m copying and pasting to each scaffold. Lame.

My question is: How do I overload the ‘find’ function for all 8
controllers in my 8 scaffolds, or create a new function that all 8 can
access, and can distinguish which object it is receiving?

Put it in a module under lib/ and include that module in all your
scaffolds. You may need to pass in some parameter that varies with
your scaffold.

With

module myModule

def someFunction
#contents
end

end

That seemed to work with instance variables, but didn’t work with

Blog.someFunction
Blog.find

but

@blog=Blog.new
@blog.someFunction

worked fine. In looking through the ruby docs, this would follow, but
they don’t give an indication of how a class instance would work. I’ll
keep browsing, but any info would be appreciated. Thanks for the help so
far, it’s pointed me in a good direction.

Spoke too soon. Doesn’t allow me to overload ‘find’.

#5

Figured it out. include Enumerable in the module. Let me know if that is
enough, seems to work.

Thanks!
