[英]How can I have the recipient field default to specific users?
QUESTION: How can I have the recipient field, automatically filled out, with a user's username, for example, using the MailBoxer gem? 问题:如何使用用户名(例如,使用MailBoxer gem)自动填写收件人字段?
I have a user admin account, and I want to have the recipient field pre-filled out, when I click on a user (non admin) profile page, in the show.html.erb view. 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,希望预先填写收件人字段。
Currently, the code used displays ALL users utilising the platform, whereas I want this specific form to only display the recipient. 当前,使用的代码显示使用该平台的所有用户,而我希望此特定表格仅显示收件人。
I am using the mailboxer gem, and I have the subject and message field already pre-filled and working. 我正在使用邮箱管理器gem,并且我的主题和消息字段已经预先填写并可以正常工作。
The code for the form, which is in the show.html.erb view: 表单的代码位于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 %>
you can use attribute selected :selected => @user.id (based your code above you have @user) 您可以使用selected属性:selected => @ user.id(基于您具有@user的代码)
<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>
