我正在将邮箱 gem 实现到我的应用程序中,并认为这应该可以工作,但出现上述错误,我认为这与 ||= 运算符有关
我得到这个
conversations_controller.rb:16: formal argument cannot be an instance variable def
trash_folder @trash ||= current_user.mailbox.trash.all end ^
/home/action/booklist/app/controllers/conversations_controller.rb:16: syntax error,
unexpected tOP_ASGN, expecting ';' or '\n' def trash_folder @trash ||=
current_user.mailbox.trash.all end ^
/home/action/booklist/app/controllers/conversations_controller.rb:18: syntax error, unexpected '.', expecting ';' or '\n' def trash conversation.move_to_trash(current_user)
... ^ /home/action/booklist/app/controllers/conversations_controller.rb:18: syntax
error, unexpected tIDENTIFIER, expecting end-of-input ...rash(current_user) redirect_to
:conversations end ... ^
对话控制器:
class ConversationsController < ApplicationController
helper_method :mailbox, :conversation
def index
@conversations ||= current_user.mailbox.inbox.all
end
def reply
current_user.reply_to_conversation(conversation, *message_params(:body, :subject))
redirect_to conversation
end
def trash_folder @trash ||= current_user.mailbox.trash.all end
def trash conversation.move_to_trash(current_user) redirect_to :conversations end
def untrash conversation.untrash(current_user) redirect_to :back end
def empty_trash current_user.mailbox.trash.each do |conversation| conversation.receipts_for(current_user).update_all(:deleted => true)
end
redirect_to :conversations
end
private
def mailbox
@mailbox ||= current_user.mailbox
end
def conversation
@conversation ||= mailbox.conversations.find(params[:id])
end
def conversation_params(*keys)
fetch_params(:conversation, *keys)
end
def message_params(*keys)
fetch_params(:message, *keys)
end
def fetch_params(key, *subkeys)
params[key].instance_eval do
case subkeys.size
when 0 then self
when 1 then self[subkeys.first]
else subkeys.map{|k| self[k] }
end
end
end
对话视图索引:
<% @conversations.each do |conversation| %>
<% if participant != current_user %>
<%= participant.name, participant %>
<% end %>
<%= link_to conversation.subject, conversation %>
<%= conversation.updated_at.strftime("%a, %m/%e/%Y %I:%M %p") %>
<%= link_to "Move to Trash", {:controller => "conversations", :action => "trash", :id => conversation.id}, :title=> "Move to Trash", :method=>'post' %>
<% end %>
并链接到 current_user_session 路径中的收件箱
<%= link_to "inbox", conversations_path %>
我有其他观点,但我认为问题出在对话控制器中。我不确定这些错误是怎么回事,它应该可以工作
