Question

我有两个模型，用户和治疗（您可以将其视为一条消息）。

用户：

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

治疗：

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

我在处理控制器设置'被请求者'时遇到了麻烦：

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

问题我试图替换为：User.find（params [：id]），希望找到当前'users / show'视图中的用户，但是我收到此错误：

找不到没有ID的用户

我也试过User.find（params [：treating] [：requestee_id]），但这也没用。有任何想法吗？

谢谢！

编辑：

views / shared / _treating_form.html.erb（这引用了用户控制器中的@received_treating，show action）：

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

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

编辑：添加其他用户个人资料页面：

<% 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

我认为只需在hidden_field中添加@user.id即可。

<%= 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" %>

您还可以填充字段

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

在控制器上只需

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

我怀疑这是否有效，但我认为它可以帮助你。

将用户别名设置为邮件收件人
