如何在Ruby控制器中打印多个变量？

Question

I am totally new in ruby. My Ruby version 2.2. I have an edit profile form. I want to show both the table and form data in two different different place. Please check my code

users_controller.rb

def edit_profile
    @user = User.get_profile(session[:user_id])
    raise $user.inspect
    respond_to do |format|
          if params[:user][:avatar]
            params[:user][:photo] = orginal_file_upload params[:user][:avatar]
          end
          raise params.inspect
          if @user.update(user_params)
            format.html { redirect_to :back, notice: 'Your profile was successfully updated.' }
            format.json { render :show, status: :ok, location: @user }
          else
            format.html { render :my_profile }
            format.json { render json: @user.errors, status: :unprocessable_entity }
          end
     end
end

Here I have define raise $user.inspect and raise params.inspect I want to get both data. But here in my page only coming first one. Please check and let me know how to get my both array value.

Thank you.

Answer 1

raise is a mechanism of throwing errors. raise $user.to_s returns the control out of action. You can use puts method to display the values in controller.

The correct code will be:

def edit_profile
@user = User.get_profile(session[:user_id])

respond_to do |format|
      if params[:user][:avatar]
        params[:user][:photo] = orginal_file_upload params[:user][:avatar]
      end

      @user.update(user_params)
      format.html { render :inline => "User<p> ID:<%= @user.id %><br>NAME: <%= @user.name %><br>EMAIL: <%= @user.email %></p>Params <p><%= params.inspect%></p>".html_safe }


 end
end

Answer 2

Assign them to instance variables like @user and @params and access them in your views. Having said that you already have assigned @user variable and params is accessible in your views automatically.

# In your view
<%= @user.name %>

<%= params %>

Also, consider making your controller RESTful. You can send PUT request to your controllers URL (eg. PUT profile/1 ) it will automatically call your ProfileController#edit method.
