[英]LoadError Unable to autoload constant Message
In my app; 在我的应用程序; when I submit form, I get this error: 当我提交表单时,我收到此错误:
LoadError at /questions
Unable to autoload constant Message, expected /app/models/message.rb to define it
It points to the create
action in the Questions
controller: 它指向Questions
控制器中的create
动作:
@message = current_user.messages.new(:subject => "You have a question from #{@question.sender_id}"`
Message model: 消息模型:
class Mailboxer::Message < ActiveRecord::Base
attr_accessible :notification_id, :receiver_id, :conversation_id
end
By convention in rails (and this is enforced by autoloader), file paths should match namespaces. 按惯例,在rails中(这是由自动加载器强制执行的),文件路径应该与命名空间匹配。
So, if you have a Mailboxer::Message
model, it should be in app/models/mailboxer/message.rb
. 因此,如果您有一个Mailboxer::Message
模型,它应该在app/models/mailboxer/message.rb
。
Additionally, you probably have autoloader kicking in when trying to load a Message
class (my guess is that it happens from within ActAsMessageable). 此外,您可能在尝试加载Message
类时启动了自动加载器(我的猜测是它发生在ActAsMessageable中)。 It looks for a message.rb
file in load path, find it in app/model/
and thus load that file so it can find the Message
class. 它在加载路径中查找message.rb
文件,在app/model/
找到它,然后加载该文件,以便它可以找到Message
类。
Problem is, it doesn't find a Message
class in that file, only a Mailboxer::Message
class (which is radically different). 问题是,它在该文件中找不到Message
类,只找到一个Mailboxer::Message
类(它完全不同)。 This is why it throws "Unable to autoload constant Message, expected /app/models/message.rb to define it". 这就是它抛出“无法自动加载常量消息,预期/app/models/message.rb来定义它”的原因。
To fix that, create directory app/models/mailboxer/
and put Mailboxer::Message
in it. 要解决此问题,请创建目录app/models/mailboxer/
并将Mailboxer::Message
放入其中。
I got this during integration testing. 我在集成测试期间得到了这个。 Turns out, it was fixtures related. 事实证明,这与灯具有关。 Had to delete the my unused file in /test/fixtures/wrong_name.yml 不得不删除/test/fixtures/wrong_name.yml中我未使用的文件
As stated in the documentation, to send a message from A
model to B
model you have to add: 如文档中所述,要将A
模型中的消息发送到B
模型,您必须添加:
acts_as_messageable
in both models. 在两个模型中。
And then do: 然后做:
a.send_message(b, "Body", "subject")
So in your models: 所以在你的模特中:
class User < ...
act_as_messageable
end
@question_sender
must be a User
instance. @question_sender
必须是User
实例。
@question_sender.send_message({attr_accessor_hash}, recipient_user, @question.body, "You have a question from #{@question_sender.id}")
As long as the attr_accessor
is not related to the gem, and the method send_message is not aware of this attributes you will have to redefine it: 只要attr_accessor
与gem无关,并且send_message方法不知道此属性,您将不得不重新定义它:
https://github.com/mailboxer/mailboxer/blob/master/lib/mailboxer/models/messageable.rb#L60 https://github.com/mailboxer/mailboxer/blob/master/lib/mailboxer/models/messageable.rb#L60
add the attr_accessor_hash to method 将attr_accessor_hash添加到方法中
def send_message({attr_accesor_hash}, recipients, msg_body, subject, sanitize_text=true, attachment=nil, message_timestamp = Time.now)
And look at the code add the fields where you need as: attr_accessor["param"]
并查看代码添加您需要的字段: attr_accessor["param"]
Notice these lines; 注意这些线;
@question = Question.new(params[:question])
@question.message = @message
and ; 和;
attr_accessible :answer, :question, :sender_id, :recipient_id, :conversation_id
The @question.message
line is calling an attribute that is not accessible in the Question Model
so do this; @question.message
行调用了一个在Question Model
无法访问的属性,所以这样做;
attr_accessible :answer, :question, :sender_id, :recipient_id, :conversation_id, message
