Question

我一直在尝试自定义Mailboxer gem以满足我的目的。还有一些其他SO帖子引用了类似的功能，但我想问这个问题，因为它有些不同。

我重构了我的消息控制器：

def new
  @user = User.find_by(id: params[:user])
end

def create
  recipients = User.where(id: params['recipients'])
  conversation = current_user.send_message(recipients, params[:message][:body], params[:message][:subject]).conversation
  flash[:success] = "Message has been sent!"
  redirect_to conversation_path(conversation)
end

要：

def new
  @user = User.find_by(id: params[:user])
  @message = current_user.messages.new
  @listing = Listing.find_by(id: params[:listing])
end

def create
  @recipient = User.find_by(id: params[:user])
  conversation = current_user.send_message(@recipient, "Hello", "Subject").conversation
  flash[:notices] = ["Your message was successfully sent to the seller"]
  redirect_to root_path
end

然后我又添加到messages / new.html.erb：

Send a message to
<%= @user.email %>
<%= form_tag({controller: "messages", action: "create"}, method: :post) do %>
  <%= hidden_field_tag(:listing, "#{@listing.id}") %>
  <%= hidden_field_tag(:user, "#{@user.id}") %>
  <%= submit_tag 'Send Message', class: "btn btn-primary" %>
<% end %>

这允许我访问我发送消息的用户对象以及列表ID，以便消息可以链接到列表。

用户模型包括：acts_as_messageable

我没有在这里绘制任何错误，但在rails控制台中验证后，我希望发送消息的用户为@user.mailbox.conversations

为零

如果有人试图用Mailboxer做同样的事情就能解释我哪里出错了会非常感激。

conversation = current_user.send_message(@recipient, "Hello", "Subject").conversation

我知道这一行可能很关键 - 在将参数传递给Mailboxer gem提供的.conversation方法之后，我并不完全理解send_message的目的。

我想发布我的最终解决方案。我最终推出了自己的消息传递解决方案，从中期https://medium.com/@danamulder/tutorial-create-a-simple-messaging-system-on-rails-d9b94b0fbca1的优秀帖子中获得了很多灵感。

它远非完美，并且在查询控制器中有大量的重构需要发生，但它是有效的并且解决了我原来的问题。

使用以下关联创建了一个查询类。

class Inquiry < ActiveRecord::Base
  belongs_to :listing
  belongs_to :sender, :foreign_key => :sender_id, class_name: "User"
  belongs_to :recipient, :foreign_key => :recipient_id, class_name: "User"
  has_many :messages, dependent: :destroy, validate: false

  accepts_nested_attributes_for :messages, reject_if: proc { |attributes| attributes["message"].blank? }

  validates_presence_of :sender, :recipient, :listing
  validates_uniqueness_of :sender_id, :scope => :recipient_id

  scope :between, -> (sender_id,recipient_id) do
    where("(inquiries.sender_id = ? AND inquiries.recipient_id =?) OR (inquiries.sender_id = ? AND inquiries.recipient_id =?)", sender_id,recipient_id, recipient_id, sender_id)
  end
end

然后是与每个查询相关联的消息类。

class Message < ActiveRecord::Base
  belongs_to :user
  belongs_to :inquiry

  validates_presence_of :body, :inquiry_id, :user_id
end

然后创建了一个InquiriesController

class InquiriesController < ApplicationController

  def index
    @users = User.all
    @inquiries = Inquiry.all
  end

  def new
    @sender = User.find_by(id: params[:sender])
    @recipient = User.find_by(id: params[:recipient])
    @listing = Listing.find_by(id: params[:listing])

    @inquiry = current_user.inquiries.new
    @message = @inquiry.messages.build
  end

  def create
   @sender = User.find_by(id: params[:sender_id])
   @recipient = User.find_by(id: params[:recipient_id])
   @listing = Listing.find_by(id: params[:listing_id])
   if Inquiry.between(@sender,@recipient).present?
     @inquiry = Inquiry.between(@sender, @recipient).first
   else
     @inquiry = Inquiry.create!(inquiry_params)
     @inquiry.listing << Listing.find_by(id: params[:listing_id])
   end
   redirect_to inquiry_messages_path(@inquiry)
 end

 private
 def inquiry_params
   params.permit(:sender_id, :recipient_id, :listing_id)
 end

在我的列表/展示页面中，我会通过发件人，收件人和列表ID来填充查询对象。

<%= link_to "Contact the Seller", inquiries_path(sender_id: current_user.id, recipient_id: @user.id, listing_id: @listing.id), method: 'post' %>

然后允许查询/索引：

<% @inquiries.each do |inquiry| %>
  <% if inquiry.sender_id == current_user.id || inquiry.recipient_id == current_user.id %>
    <% if inquiry.sender_id == current_user.id %>
      <% recipient = User.find(inquiry.recipient_id) %>
    <% else %>
      <% recipient = User.find(inquiry.sender_id) %>
    <% end %>
    <div>
      <%= link_to "Messages with #{recipient.email} about #{inquiry.listing.title}", inquiry_messages_path(inquiry)%>
    </div>
  <% end %>
<% end %>
