ruby-on-rails – Ruby on Rails ActiveRecord :: AssociationTy

RepliesController #create中的ActiveRecord :: AssociationTypeMismatch

消息(#58297820)预期,得到字符串(#1635350)

我一直试图弄清楚问题是什么,现在没有运气.

您将在下面找到我的迁移,模型,视图和控制器的代码.

移民

def self.up
create_table :replies do |t|
  t.integer :message_id,:null => false
  t.integer :sender_id,:null => false
  t.text :message,:null => false
  t.timestamps
end
end

模型

class Reply < ActiveRecord::Base
belongs_to :message

validates_presence_of :message

cattr_reader :per_page
@@per_page = 10
end

视图

<% form_for(@reply) do |f| %>
<table>
                    <tr>
                        <td><%= f.text_area :message %></td>
                    </tr>
                    <%= f.hidden_field :message_id,:value => @message.id %>
                    <tr>
                        <td><%= f.submit 'Reply',:id => 'replySubmit' %></td>
                    </tr>
                </table>


            <% end %>

调节器

def create
account = Account.getAccountById(session[:user])
message = Message.find(
    params[:reply][:message_id],:conditions => ["messages.account_id=? or messages.sender_id=?",account.id,account.id]
  )
if message
  @reply = Reply.new
  @reply.message_id = message.id
  @reply.sender_id = account.id
  @reply.message = params[:reply][:message]
  if @reply.save
    flash[:message] = "Reply successfully submitted."
    redirect_to(messages_path)
  else
    flash[:warning] = "Message cannot be blank."
    redirect_to(messages_path)
  end
else
  redirect_to(messages_path)
end
rescue ActiveRecord::RecordNotFound
render :template => "error"
end

我很感激提供的任何帮助.我会一直试图找出问题所在.

谢谢.
