Where do I put code when I share a partial between two controllers

Hello, I’m new in Rails and much more in MVC, and I’m absolutly lost.

The question is more clearly this:

If I have a partial, than uses a controller/method (called X) for
requery itself via JS, and this partial is viewed in two screens ( two
controllers, menu and sarch). where do you place this code (X), In which
controller and views, and js.rjs?

where can i see an example?

thanks you.

It doesn’t matter all that much. If it has a stronger affinity for one
of the controllers, then put it in that controller’s view folder, and
then in the other spot where you need to reference it, just put the
leading /modelname/partialname on the render argument.

So you have

views
bars
index.html.erb
foos
_foo.html.erb
index.html.erb

and you want to re-use the foo partial to make a list of foos in the
bars/index view, you would just do this:

render :partial => ‘/foos/foo’, :collection => @foos

in your bars index, assuming you had gathered a collection of foos in
your bars_controller inside the index method.

I think this is just basic to how Rails works. The controller responds
to requests with methods. Those methods may be further decomposed into
other methods and variable values, but your statement is true as far
as I understand it.

Thanks for your response, sorry but my unknows go far away:

I have two entitys:

1- Views or Partial: and I undersant this: render :partial /shred/foo

2- Method/controller (X). now I place this method in
application_controller and the .js.rjs in views/application/X.js.rjs. It
works

But I do that because in “menu” controller and “Maintenance” contoller I
call X, but not as a “redirecto_to” otherwise as a normal call, as if it
was a function, only to initialize variables.

So that, I need to put X method in applicationController, to be seen
from the others controllers (menu and Maintenance).

–> And this is weird, ¿ or not ? the X method is used for two porpuses:
as a response of a browser JS request, and as “function”

And to tho that I put in X:

if request.xhr?
  respond_to do |format|
      format.js
  end
end

thanks again
