passing id in multi part form

Hi Guys,

I'm building an application that allows users to first fill in details of a recent trip to the gym, once they click submit these details are saved to a database table and redirects to a form that lets them input the exercises they carried out and saves them in a second table.

I need to know how to pass the id of the update to the second form, my controller for the update currently looks like this:

def update     @update = Update.find(params[:id])     if @update.update_attributes(params[:update])       flash[:notice] = 'Update was successfully updated.'       redirect_to :action => 'show', :id => @update     else       render :action => 'edit'     end   end

the redirect works fine, I'm pretty certain the :id=> is completely wrong but I'm not sure how to go about this...

cheers, Lee.

Lee, try:

redirect_to :action => 'show', :id => @update.id

or, since it's still on the params:

redirect_to :action => 'show', :id => params[:id]

Or, if you are using RESTful routes, you can just do:

redirect_to @update

And that will default to the show action with the @update's ID.

Another thing to remember: if you need to pass data back and forth between requests, that's one of the things the session hash is good for:

Action #1: session[:foo] = "bar"

Action #2:

foo = session[:foo] # => foo = "bar"

HTH!
