If I have a template (.rhtml) that lists displays all records, and I want to filter the list, say a todo list and only show "done" items I want to use the same template and not have to create a "done.rhtml" and a "notdone.rhtml" for the filtering - that''s three templates when one should work. /todo displays all items /todo/done displays only done items /todo/notdone displays items still to be done All of these paths should use the one simple template. Where do you override the template displayed? If there is a better way of going about this? -- Craig Beck http://luckybonza.com AIM: Kreiggers
I''d do the filtering in the controller. For example, if you have an
AR object called Items, and the varialbe you use in the template is
@items, then each method in the coltroller can filter at the model
level and return the filtered data in the @items variable to the
template. Then, call render
(http://rails.rubyonrails.com/classes/ActionController/Base.html#M000154)
to use {APP_BASE}/views/todo/todo.rhtml for each action. e.g.:
todo_controller.rb:
def index
#render all for the default
all
render_action ''all''
end
def all
@items = Items.find_all
render ''todo/todo''
end
def done
@items = Items.find_all "is_done = 1"
render ''todo/todo''
end
def notdone
@items = Items.find_all "is_done = 0"
render ''todo/todo''
end
Then your urls would be:
/todo (same as /todo/all)
/todo/done
/todo/notdone
That should do it! :)

In your case use render_action "index" or whatever the default template is. http://api.rubyonrails.com/ -Jeff ----- Original Message ----- From: "Craig Beck" <craigbeck-sUNYKzuJffo33s2pWanAEQ@public.gmane.org> To: <rails-1W37MKcQCpIf0INCOvqR/iCwEArCW2h5@public.gmane.org> Sent: Tuesday, April 05, 2005 4:29 PM Subject: [Rails] re-using templates> If I have a template (.rhtml) that lists displays all records, and I > want to filter the list, say a todo list and only show "done" items I > want to use the same template and not have to create a "done.rhtml" and > a "notdone.rhtml" for the filtering - that''s three templates when one > should work. > > /todo displays all items > /todo/done displays only done items > /todo/notdone displays items still to be done > > All of these paths should use the one simple template.

Does #all actually return to #index such that "render_action ''all''" can be called? I guess I''ll just read the API docs for render and render_action, but I''ve read them before and obviously don''t fully get them. Oh well... Gavin
render_action is just a shortcut for render. It fills in the last part of the path with the controller name. E.g. render ''todo/todo'' is the same as render_action ''todo'' (as long as you''re calling it from todo_controller.rb :)). I probably shouldn''t have mixed the two. It is a little confusing. I just yanked some of that code out of one of my apps. The docs do explain it, though. :) On Apr 5, 2005 6:30 PM, Gavin Sinclair <gsinclair-81uBx+iSpXA0n/F98K4Iww@public.gmane.org> wrote:> On Wednesday, April 6, 2005, 8:57:42 AM, Nathan wrote: > > > def index > > #render all for the default > > all > > render_action ''all'' > > end > > > def all > > @items = Items.find_all > > render ''todo/todo'' > > end > > In that code, #index calls #all, which calls "render ''todo/todo''". > Does #all actually return to #index such that "render_action ''all''" > can be called? > > I guess I''ll just read the API docs for render and render_action, > but I''ve read them before and obviously don''t fully get them.

Thanks, I was getting lost in the docs wondering where I was supposed to be looking for the solution. Problem solved, and I''ve read a lot of documentaion too boot, so I''ve picked up a few more things on the way...
