How to pass objects from one controller to another controller

On an unsuccessful save, I would like to redirect to the previous view but with the error message.

redirect_to user_path(@user_id), errors: @user.errors

but in the view, when I check for errors I get an undefined variable errors.

I am not using the same controller new and create, so I can't have @user.errors.any in new.html.erb. I have two different controllers, one in which form is there, and another controller which will take care of create, if the create is not happening I need to redirect to the previous controller.

You have to pass the parameters inside the redirect_to helper like below,

redirect_to user_path(id: @user_id, error: @user.errors.messages)

Please check the rake routes and pass the appropriate key for id, whether it's :id, or :user_id

You may need to use render instead of redirect_to. Something like this:

# controller_1
def step_1
  @user = User.new
  @user.do_something
  ...
end

# controller_2
def step_2
 if @user.save?
   # redirect to another...
 else
   render 'controller_1/step_1`
 end
end

Then on view step_1.html.erb, you can print out errors of @user with @user.errors.
