軌道上紅寶石對話的搜索功能

Question

我新來的鐵軌。我想爲我的Rails應用程序添加一個搜索功能。用戶可以搜索他與其他用戶進行的對話。在那個搜索中，他可以鍵入消息的關鍵字或他聊天的用戶名。可有一個人指導我該...

conversation.rb是，

class Conversation < ActiveRecord::Base 
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 

validates_uniqueness_of :sender_id, scope: :recipient_id 

scope :involving, -> (user) do 
    where("conversations.sender_id = ? OR conversations.recipient_id = ?", user.id, user.id) 
end 

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

end 

message.rb是，

class Message < ActiveRecord::Base 


belongs_to :conversation 
    belongs_to :user 

    validates_presence_of :content, :conversation_id, :user_id 

    def message_time 
    created_at.strftime("%v") 
    end 

end 

conversations_controller.rb是，

class ConversationsController < ApplicationController 
before_action :authenticate_user! 

def index 
    @users = User.all 
    @conversations = Conversation.involving(current_user) 
end 

def create 
    if Conversation.between(params[:sender_id], params[:recipient_id]).present? 
     @conversation = Conversation.between(params[:sender_id], params[:recipient_id]).first 
    else 
     @conversation = Conversation.create(conversation_params) 
    end 

    redirect_to conversation_messages_path(@conversation) 
end 

private 

    def conversation_params 
     params.permit(:sender_id, :recipient_id) 
    end 

end 

messages_controller.rb是，

class MessagesController < ApplicationController 
before_action :authenticate_user! 
before_action :set_conversation 

def index 
    if current_user == @conversation.sender || current_user == @conversation.recipient 
     @other = current_user == @conversation.sender ? @conversation.recipient : @conversation.sender 
     @messages = @conversation.messages.order("created_at DESC") 
    else 
     redirect_to conversations_path, alert: "You don't have permission to view this." 
    end 
end 

def create 
    @message = @conversation.messages.new(message_params) 
    @messages = @conversation.messages.order("created_at DESC") 

    if @message.save 
     respond_to do |format| 
      format.js 
     end 
    end 
end 

private 

    def set_conversation 
     @conversation = Conversation.find(params[:conversation_id]) 
    end 

    def message_params 
     params.require(:message).permit(:content, :user_id) 
    end 
end 

有人可以指導我編寫搜索功能並查看搜索結果。我嘗試過兩種不同的類型，但沒有奏效。在此先感謝

在談話的模型或任何你把它命名爲把這樣的搜索方法：

def self.search(search) 
if search 
    where(['title LIKE ? or content LIKE ?', "%#{search}%","%#{search}%"]) 
end 

末

然後在指標有這樣的事情：

<%= form_tag conversations_path, :method => 'get' do %> 
<%= text_field_tag :search, params[:search] %> 
<%= submit_tag "Search", name: nil %> 
<% end %> 

最後在控制器中有這樣的東西：

@conversation= Conversation.search(params[:search])

注意第一個是我認爲最適合你的東西。這是一個簡單的搜索，它適合你所說的。
