Instance variable in controller -> views with RJS?

Hi everyone,

This should be pretty simple…
If you have an instance variable in a controller passed to its view, and
you have <% form_remote_tag :url => { :action => ‘other_action’ } do -%>
etc <% end %>, can you access the instance variable in the action
other_action?

You’re not really changing the view…

The idea is that I really need to store a variable and have it go from
first action -> view -> second action -> manipulated -> passed back to
the view in render :update. If the above is not possible, what is the
best way to do this? Sessions?

Thanks.

i am new to ruby but i believe you can do it with the local option on
partial.

pass it in on the form

<% form_remote_tag :url => {:action => ‘other_action’, :the_var =>
@the_var } do -%>
then in the destination action, set

@the_var = params[:the_var]

No, that’s not what he meant.

Alright. But you can’t access it directly from the second action right?
The variable I want to pass is a very long array of objects, and I was
afraid it wasn’t going to be efficient if I passed it through a form (or
a session).

When you submit that form it will make a ‘new’ request back to the
server. Unfortunately rails really resets ‘per request’ – except for
session vars and things you pass back to it.

only if you trust the security of your clients’ computers :slight_smile:
I suppose if it’s sensitive save it to your session [or to a database
then reload it]

pass it through the form?

bearing in mind of course that with the default session store the
session data is on the client’s computer.

And keeping in mind that SSL should be used to encrypt transmitting
sensitive information over a hostile network like the internet.
