自定義Mailboxer gem-Rails 4-發送鏈接到列表的消息

Question

我一直在嘗試自定義Mailboxer gem以適合我的目的。 還有其他一些SO帖子引用了相似的功能，但是我想問這個問題，因為它有些不同。

我從這里重構了消息控制器：

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

至：

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，我還添加到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 %>

這使我可以訪問向其發送消息的用戶對象以及列表ID，以便可以將消息鏈接到列表。

Github倉庫： https : //github.com/benhawker/rails_marketplace/tree/master/app

用戶模型包括： acts_as_messageable

我沒有在此處繪制任何錯誤，但是在Rails控制台中進行驗證之后，我希望向其發送消息的用戶的@user.mailbox.conversations為@user.mailbox.conversations

如果嘗試使用Mailboxer進行相同操作的任何人都能解釋我要去哪里，那將非常感謝。

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

我知道這行可能是關鍵-在將參數傳遞給Mailboxer gem提供的send_message方法后，我不完全了解.conversation的目的。

我想為此發布最終的解決方案。 我最終從我在Medium https://medium.com/@danamulder/tutorial-create-a-simple-messaging-system-on-rails-d9b94b0fbca1上的一篇出色文章中獲得了很多靈感，推出了自己的消息傳遞解決方案。

它遠非完美，需要在查詢控制器中進行大量重構，但這是功能性的，可以解決我的原始問題。

使用以下關聯創建了一個查詢類。

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

然后是與每個查詢關聯的消息類。

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

  validates_presence_of :body, :inquiry_id, :user_id
end

然后創建一個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

然后，在我的列表/顯示頁面中，我通過發件人，收件人和列表ID來填充查詢對象。

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

然后允許查詢/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 %>
