Question

I have two models, user and treating (which you can think of as a message).

User:

class User < ActiveRecord::Base
    attr_accessible :name, :email, :password, :password_confirmation
    has_secure_password

    has_many :sent_treatings, :foreign_key => "requestor_id", :class_name => "Treating", dependent: :destroy
    has_many :received_treatings, :foreign_key => "requestee_id", :class_name => "Treating", dependent: :destroy

end

Treating:

class Treating < ActiveRecord::Base
  attr_accessible :intro, :proposed_date, :proposed_location

  validates :intro, presence: true, length: { maximum: 190 }
  validates :requestor_id, presence: true
  validates :requestee_id, presence: true

    belongs_to :requestor, class_name: "User"
    belongs_to :requestee, class_name: "User"

    default_scope order: 'treatings.created_at DESC'

end

I’m having trouble in my treatings controller setting ‘requestee’:

class TreatingsController < ApplicationController
    before_filter :signed_in_user

    def create
        requestee = ?
        requestor = current_user
        @received_treating = requestee.received_treatings.build(params[:treating])
        @received_treating.requestor = requestor

        if @received_treating.save
            flash[:success] = "Treating request sent!"
            redirect_to users_path
        else
            render 'static_pages/home'
        end
    end
end

The question mark I tried to replace with: User.find(params[:id]), hoping that the user in the current ‘users/show’ view would be found, but I get this error:

Couldn’t find User without an ID

I also tried User.find(params[:treating][:requestee_id]), but this didn’t work either. Any ideas?

Thanks!

EDIT:

views/shared/_treating_form.html.erb (this references @received_treating in the users controller, show action):

<div class="field">
    <%= f.text_area :intro, placeholder: "Write your introduction here..." %>
</div>

<%= f.submit "Send", class: "btn btn-large btn-primary" %>

EDIT: adding other user profile page:

<% provide(:title, @user.name) %>
<div class="row">
    <aside class="span4">
        <section>
            <h1>
                <%= gravatar_for @user %>
                <%= @user.name %>
            </h1>
        </section>
        <% if signed_in? %>
            <section>
                    <%= render 'shared/treating_form' %>
            </section>
        <% end %>
    </aside>
    <div class="span8">
        <% if @user.received_treatings.any? %>
        <h3>Treating requests (<%= @user.received_treatings.count %> received)</h3>
        <ol class="treatings">
            <%= render @received_treatings %>
        </ol>
            <%= will_paginate @received_treatings %>
        <% end %>
    </div>
</div>

Answer 1

I think just adding @user.id in a hidden_field would work.

<%= f.hidden_field :requestee_id, :input_html => { :value => @user.id }
<div class="field">
    <%= f.text_area :intro, placeholder: "Write your introduction here..." %>
</div>

<%= f.submit "Send", class: "btn btn-large btn-primary" %>

You could also populate the field doing

<%= form_for @user.received_treatings.build do %>
  <%= f.hidden_field :requestee_id %>
  ....

On the controller just do

@received_treating = current_user.sent_treatings.build params[:treating]

I have some doubts if this works but I think it should help you out.
