Question

我是铁杆新手，所以提供任何帮助都会非常感激。

目标：

当用户在表单上留下注释（注释）时，i 希望能够知道userr_id＆amp; form_id就在那张纸条上。一世我不确定如何将form_id链接到注释。当我创建一个注释时，它会告诉我哪个用户（userr_id）创建了它但它没有告诉我该注释属于哪个表单（form_id） - 任何帮助都会非常感激 - 谢谢

我目前有以下模型和视图创建

[model] note belongs_to：userj
[model] note belongs_to：form
[model] form has_many：notes
[model] userj has_many：notes

我的控制台：

2.1.2 :062 > ap Note.all
  Note Load (0.4ms)  SELECT "notes".* FROM "notes"
[
    [0] #<Note:0x007fbde666cd70> {
                :id => 4,
           :content => "hello",
           :form_id => nil,
        :created_at => Thu, 09 Jul 2015 23:17:19 UTC +00:00,
        :updated_at => Thu, 09 Jul 2015 23:17:19 UTC +00:00,
          :userr_id => 1
    }
]

模型：

note.rb
class Note < ActiveRecord::Base
  belongs_to :userj
  belongs_to :form
end

form.rb
class Form < ActiveRecord::Base
  has_many :notes
end

userr.rb
class Userr < ActiveRecord::Base
  # Include default devise modules. Others available are:
  # :confirmable, :lockable, :timeoutable and :omniauthable
  devise :database_authenticatable, :registerable,
         :recoverable, :rememberable, :trackable, :validatable, :confirmable

  has_many :notes
end

形式/ show.html.erb

<p>
  <strong>Firstname:</strong>
  <%= @form.firstname %>
</p>

<p>
  <strong>Lastname:</strong>
  <%= @form.lastname %>
</p>

<p>
  <strong>Number:</strong>
  <%= @form.number %>
</p>

<p>
  <strong>Email:</strong>
  <%= @form.email %>
</p>


<h2> Recruiters Notes on jobseeker form</h2>
<p>
  <%= render 'notes/form' %>
</p>

笔记/ _form.html.erb

我尝试按照下面的方式传递form_id，但是当我创建一个注释时一张表格，它没有告诉我这张纸币属于哪种形式 form_id列（在注释表中）在控制台中指出nill

<%= simple_form_for(@note) do |f| %>
  <%= f.error_notification %>

  <div class="form-inputs">
    <%= f.input :content %>
    <%= f.hidden_field :form_id, value: params[:form_id] %>
  </div>

  <div class="form-actions">
    <%# f.button :submit %>
    <%= f.button  :submit , name: "form", value: params[:form_id] %>
  </div>
<% end %>

notes_controller.rb

class NotesController < ApplicationController

    respond_with(@notes)

    @note = Note.new
    respond_with(@note)

      @note = Note.find(params[:id])

通常你不应该尝试在视图中使用params。在这种情况下，您可以：

通过与@note中的表单（@note = @form.notes.build）的关联构建FormsController#show实例变量，并在表单中包含隐藏字段;
将@form实例传递给partial，以便它可以使用以下格式：

形式/ show.html.erb：

    # ...
    <%= render partial: 'notes/form', locals: { form: @form } %>

笔记/ _form.html.erb

    # ...
    <%= f.hidden_field :form_id, value: form.id %>
