未定义的方法`acts_as_messageable_messages_path` [英] Undefined Method `acts_as_messageable_messages_path`

问题描述

我正在使用行为即讯息（一种铁轨宝石）我有。

然而，在我的messages_controller中，我有

  def新
 @message = ActsAsMessageable :: Message.new 
结束
  

和in我的观点我有

 <％= form_for（@message）do | f | ％GT; 
  

引发以下错误：

未定义的方法`acts_as_messageable_messages_path'

我不确定为什么会发生这种情况。请尝试明确指出您希望表单指向哪个路径（这应该是 messages＃create ） / code> action）：

 <％= form_for（@message）：url => messages_path，：method => ：post do | f | ％GT; 
< div class =field> 
<％= f.label：to％>< br /> 
<％= f.email_field：to％> 
< / div> 
< div class =field> 
<％= f.label：topic％>< br /> 
<％= f.text_field：topic％> 
< / div> 
< div class =field> 
<％= f.label：body％>< br /> 
<％= f.text_area：body％> 
< / div> 
 
< button type =submitclass =btn primary>发送< / button> 
< button type =resetclass =btn>取消< / button> 
<％end％> 
  

这里假设你在 routes.rb

$ $ p $ resources：messages


另外，请确保您将必填字段传递给 ActsAsMessageable ： https://github.com/LTe/acts-as-messageable/wiki/Example-controller

I'm using acts-as-messageable, a rails gem, in an app i have.

However in my messages_controller i have

def new 
  @message = ActsAsMessageable::Message.new
end 

and in my view i have

<%= form_for(@message) do |f| %>

which throws the following error

undefined method `acts_as_messageable_messages_path'

I'm not really sure why this is happening with the gem.

解决方案

Try explicitly stating what path you want the form to point towards (which should be the messages#create action):

<%= form_for(@message) :url => messages_path, :method => :post do |f| %> 
  <div class="field">
    <%= f.label :to %><br />
    <%= f.email_field :to %>
  </div>
  <div class="field">
    <%= f.label :topic %><br />
    <%= f.text_field :topic %>
  </div>
  <div class="field">
    <%= f.label :body %><br />
    <%= f.text_area :body %>
  </div>

  <button type="submit" class="btn primary">Send</button>
  <button type="reset" class="btn">Cancel</button>
<% end %>

This assumes that you have this in your routes.rb file:

resources :messages

Also, make sure you are passing in the required fields to ActsAsMessageable: https://github.com/LTe/acts-as-messageable/wiki/Example-controller
