Redirect view after saving Rails model

When I:

self.save

or

save!

in a model it automatically redirects me to the show view for that given model. How can I override this? I want to save the model and then go to another action/view in the same controller.
In particular, I have a process where I save a members details, and then I want to continue the process by going to the next page, e.g. payment page, that uses the id of the saved model.

if you call save from your Model you will not be directed anywhere, it just does a direct model access save to the database. Your redirections are described in your controller in your create and update actions. you can find a list of routes by running rake routes and then pick the path you want your app to render when you save your model instance. you may have a route called payment_path which might look like this in your controller

map.payment :controller => :payments_controller, :action => index

and you would say in your create action

def create
  if @item.save(params[:item])
    redirect_to payment_path 
  else
    flash[:error] = "there was a problem"
    render :action => buy
  end
end

if you need to pass a param, like user id to your route, then you need to include that in the path parameters

redirect_to payment_path(@user) #=> automagically finds the id of active record models

In your controller you might have a block like:

def create
  @user = User.new(params[:place])

  respond_to do |format|
    if @user.save
      format.html { redirect_to(@user, :notice => 'User was successfully created.') }
      format.xml  { render :xml => @user, :status => :created, :location => @user }
    else
      format.html { render :action => "new" }
      format.xml  { render :xml => @user.errors, :status => :unprocessable_entity }
    end
  end
end

You can change the target of the redirect_to (after format.html) from here - at present it is directing you to the record for that user, ie. @user. Take a look at http://api.rubyonrails.org/classes/ActionController/Base.html for a bit more info.

You likely have a block like this in your create/update methods:

    respond_to do |format|
      if @post.save
        format.html { redirect_to(@post, :notice => 'Post was successfully created.') }
        format.xml  { render :xml => @post, :status => :created, :location => @post }
      else
        format.html { render :action => "new" }
        format.xml  { render :xml => @post.errors, :status => :unprocessable_entity }
      end
    end

So if your instance variable is named @post, and it's redirecting to the show view for the post after it saves, all you have to do is change the "redirect_to(@post, ..." part to whatever you want. Say you wanted to redirect to the root of your site - you could instead have

redirect_to(root_path, :notice => 'Post was successfully created.')

In your particular case, you could use something like this if you have your routes set up:

redirect_to(payment_page_path(@post), :notice => 'Post was successfully created.')

Hope that helps!
