Question

在我的应用程序中，我有一个列表页面，用户可以在其中显示他们的产品。

其他用户可以联系上市作者。

我在列表页面上创建了一个消息按钮，一旦点击该页面，就会重定向到Mailboxer表单并预填充收件人文本字段。我希望主题填写列表标题的文本。

我的代码：

module MessagesHelper

  # This is the helper for grabbing a User
  def recipients_options(chosen_recipient = nil)
    s = ''
    User.all.each do |user|
      s << "<option value='#{user.id}' #{'selected' if user == chosen_recipient}>#{user.name}</option>"
    end
    s.html_safe
  end

  # This is the helper for grabbing the Title from Listing
  def recipient_subject(chosen_subject = nil)
    s = ''
    Listing.all.each do |subject|
    s << "<option value='#{subject.id}' #{'selected' if subject == chosen_subject}>#{subject.title}</option>"
    end
    s.html_safe
  end
end

我的控制器

class MessagesController < ApplicationController
  before_action :logged_in_user
  # before_action :correct_user

  def new
    @chosen_recipient = User.find_by(id: params[:to].to_i) if params[:to]

    @chosen_subject = Listing.find_by(title: params[:title].to_i) if params[:title]
  end

  def create
    recipients = User.where(id: params['recipients'])
    conversation = current_user.send_message(recipients, params[:message][:body], params[:message][:subject]).conversation
    flash[:success] = "Message has been sent!"
    redirect_to conversation_path(conversation)
  end

end

我的观点

清单＆gt;显示（要联系的按钮）

<p>
  <strong>Contact Seller about "<%= @listing.title %>"</strong></br>
  <%= link_to "Send message to #{@listing.user.name}", new_message_path(to: @listing.user.id, message: @listing.title), class: 'btn btn-default btn-sm' %>
</p>

最后我的新消息表格

<%= form_tag messages_path, method: :post do %>
  <div class="form-group">
    <%= label_tag 'message[subject]', 'Subject' %>
    <%= text_field_tag 'message[subject]', recipient_subject, class: 'form-control', required: true %>
  </div>

  <div class="form-group">
    <%= label_tag 'message[body]', 'Message' %>
    <%= text_area_tag 'message[body]', nil, cols: 3, class: 'form-control', required: true %>
  </div>

  <div class="form-group">
    <%= label_tag 'recipients', 'Choose recipients' %>
    <%= select_tag 'recipients', recipients_options(@chosen_recipient), multiple: true, class: 'form-control chosen-it' %>
  </div>

  <%= submit_tag 'Send', class: 'btn btn-primary' %>
<% end %>

使用此代码，所有标题都会显示在主题字段中列出：

<option value='5' >New Samsung</option><option value='4' >Title</option><option value='3' >New listing</option><option value='2' >Something</option><option value='1' >Disco</option>

我希望该单一商家信息的标题出现，但它对我不起作用;它显示所有内容以及选项和价值代码。在此先感谢您的帮助！

使用Mailboxer Gem预填充主题文本字段/表单
