如何让收件人字段默认为特定用户？

Question

问题：如何让收件人字段自动填写用户的用户名，例如，使用 MailBoxer gem？

我有一个用户管理员帐户，当我在 show.html.erb 视图中单击用户（非管理员）个人资料页面时，我希望预先填写收件人字段。

目前，使用的代码显示所有使用该平台的用户，而我希望此特定表单仅显示收件人。

我正在使用邮箱 gem，我已经预先填写了主题和消息字段并且可以使用。

表单的代码，在 show.html.erb 视图中：

<%= form_for :conversation, url: :conversations, html: { class: "" } do |f| %>

  <div class="form-group">
    <%= f.label :recipients %>
    <%= f.select(:recipients, User.all.collect {|p| [ p.username, p.id ] }, {}, { multiple: true , class: "chosen-select form-control", :data => {:placeholder => "Please type in a username to search for a user"}})%>
  </div>

  <div class="form-group">
    <%= f.label :subject %>
    <%= f.text_field :subject, placeholder: "Subject", class: "form-control",
        value: "Hi #{@user.username}! %>
  </div>

  <div class="form-group">
    <%= f.label :message %>
    <%= f.text_area :body, class: 'form-control',placeholder: "Type your message here", rows: 4,
        value:

"Hi #{@user.username}!

I am mailing you to tell you that [INSERT ITEM NAME] is in stock.

Please come down to receive the item. %>
  </div>

  <%= f.submit "Send Message" %>

<% end %>

您可以使用属性 selected :selected => @user.id（根据您上面的代码，您有 @user）

  <div class="form-group">
    <%= f.label :recipients %>
    <%= f.select(:recipients, User.all.collect {|p| [ p.username, p.id ] }, {},  , { :selected => @user.id, multiple: true , class: "chosen-select form-control", :data => {:placeholder => "Please type in a username to search for a user"}})%>
  </div>

How can I have the recipient field default to specific users?
