Question

Right now, I have two views that are using the users#create action: users/new.thml.erb and enter_email.html.erb.

The problem is that with the current code, the user is redirected to new.html.erb when the
form in enter_email.html.erb has a validation error. So I tried this:

  def create
    @user = User.new(params[:user])
    if @user.save
      sign_in @user
      flash[:success] = "Welcome to the Sample App!"
      redirect_to @user
    else
      if params[:action] == "enter_email"
        render 'enter_email'
      else
        render 'new'
      end
    end
  end

I wanted to user to be redirected to enter_email.html.erb when the action is ‘enter_email’. But I’m still being redirected to ‘new.html.erb’.

Any suggestions to fix this? (it is because the action being performed is actually create? If so, how to modify the code to make the redirection work?)

Answer 1

I see a couple of ways to do it:

• Add a hidden field to both forms, and check in params for the value of that field, so you know which form you come from

  # in your new.html.erb view
  hidden_field_tag 'form_name', 'new'
  
  # in your enter_email.html.erb view
  

    hidden_field_tag ‘form_name’, ‘enter_email’

  # in controller
  if params[:form_name] == "enter_email"
    render 'enter_email'
  else
    render 'new'
  end
  

• Use a different action for creation, like create_from_enter_email, and direct the enter_email form to it.
