我正在构建一个自定义收件箱,在添加此行以显示所有消息后,“<% user.received_messages.each do |message| %>”我现在收到“未定义的局部变量或方法‘用户’”错误. 不知道为什么额外的代码行会导致此错误以及如何修复它。
_inbox.html:
<h2>Your Inbox</h2>
<% user.received_messages.each do |message| %>
No messages in your Inbox
<% end %>
<%= form_tag delete_multiple_user_messages_path, :method=>:post do %>
<table class="table table-bordered">
<tr>
<th>Delete?</th>
<th>Sent</th>
<th>Sender</th>
<th>Sent</th>
</tr>
<% for message in @messages %>
<tr>
<td><%= check_box_tag "delete[]", message.id %></td>
<td>
<% if message.read? %>
<%= link_to h(message.subject), user_message_path(@user, message) %>
<% else %>
<%= link_to "#{h(message.subject)} (unread)", user_message_path(@user, message) %>
<% end %>
</td>
<td><%= "#{message.sender.first_name} #{message.sender.last_name}" %></td>
<td><%=h message.created_at.to_s(:long) %></td>
</tr>
<% end %>
</table>
<%= submit_tag "Delete selected" %> |
<% end %>
<%= link_to "Compose New Message", new_user_message_path(@user)%> |
<%= link_to "View Sent Messages", user_messages_path(current_user, :mailbox => :sent)%>
索引.html:
<% if params[:mailbox] == "sent" %>
<%= render :partial => "sent" %>
<% elsif params[:mailbox] == "inbox" %>
<%= render :partial => "inbox" %>
<% elsif params[:mailbox] == "archieved" %>
