How to print multiple variable in Ruby controller? - ruby-on-rails

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

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.
