Rails - 参数形式值

Question

Hello everybody I'm looking for some help with my rails app:

I don't know why my User isn't created even i have params with value from my simple_form_for, below my controller:

  def create
    if current_user == nil
      @user = User.create(
        phone: params[:temp_phone],
        email: params[:temp_email]
        first_name: params[:temp_first_name],
        password: "test123456"
        )
      if @user.save
        @watch = Watch.new(watch_params)
        @watch.user = User.last
      else
        puts "#{@user.errors.messages}"
      end
    else
      @watch = Watch.new(watch_params)
      @watch.user = current_user
    end
  end

My view looks like this

    <%= simple_form_for @watch do |f| %>
      #DoSomething
    <% if current_user == nil %>
      <%= f.input :temp_first_name, label: "Name" %>
      <%= f.input :temp_email, label: "Email" %>
      <%= f.input :temp_phone, label: "Phone" %>
    <% end %>
    <div class="home-top-btn">
      <%= f.button :submit, "Estimer votre montre", class: "btn btn-primary btn-lg" %>
    </div>
    <% end %>

Error is: email can't be blank

Basically my goal is if current_user create watch with current_user info Else create user with params from simple_form_for then create watch

I'm pretty sure that is not the best way to go so feel free to adjust me.

Thank in advance for your help

When you submit a form you can check the parameter structure in rails server log that running on your terminal. It will look like this.

{ watch: {
    temp_email: "something@localhost.com"
    ...other details
  }
}

Mind that watch key in params and then sub hash of other params like temp_email and other keys/fields. Here what this might fix your issue. Try to replace following code in your create action.

@user = User.create(
          phone: params[:watch][:temp_phone],
          email: params[:watch][:temp_email]
          first_name: params[:watch][:temp_first_name],
          password: "test123456"
        )

Note: This will work only if you really have a something in @watch instance variable.
