Question

I know I am missing something.. I don’t know how to fix it.

I have a Message model which has a body attribute.

the controller is located under users/messages_controller.rb

my routes

  namespace :users do
    resources :messages
  end

which give

users_messages     GET    /users/messages(.:format)           users/messages#index
                   POST   /users/messages(.:format)           users/messages#create
new_users_message  GET    /users/messages/new(.:format)       users/messages#new
edit_users_message GET    /users/messages/:id/edit(.:format)  users/messages#edit
users_message      GET    /users/messages/:id(.:format)       users/messages#show
                   PUT    /users/messages/:id(.:format)       users/messages#update
                   DELETE /users/messages/:id(.:format)       users/messages#destroy

I created a partial which I render on users/show via

  <%= render :partial => 'users/messages/sendme' %>

_sendme.html.erb

<%= form_tag(users_messages_path) do %>
         <%= text_area_tag "Message" %>
         <%= submit_tag 'Submit' %>
<% end %>

but when I submit a message, and it goes to the create action in messages_controller I can’t pull the id of the user from which the message was sent.
The params that I get are

pry(#<Users::MessagesController>)> params
=> {"utf8"=>"Γ£ף",
 "authenticity_token"=>"IrcPBHgBp/BI...mBbOQx7gcJc5xNtAFs=",
 "Message"=>"test",
 "commit"=>"Submit",
 "action"=>"create",
 "controller"=>"users/messages"}

The URL of the users/show is http://localhost:3000/users/24
What do I need to add so I can get the user’s ID in the params?

If you have the @user available in your form, create a hidden_field_tag inside it like this:

<%= hidden_field_tag :id, @user.id %>

Then, when you submit your form, the params[:id] would be populated as @user.id.
