```haml

|
133
|
+
.message{"data-message-id": "#{message.id}"}
|
|
134
|
+
```
|
|
135
|
+
[2]同じgroup.idの場合のみここの処理がされ、、、
|
|
136
|
+
```jquery
|
|
137
|
+
var reloadMessages = function() {
|
|
138
|
+
if (window.location.href.match(//groups/\d+/messages/)){
|
|
139
|
+
var last_message_id = $('.message:last').data("message-id")
|
|
140
|
+
$.ajax({
|
|
141
|
+
url: 'api/messages',
|
|
142
|
+
type: 'get',
|
|
143
|
+
dataType: 'json',
|
|
144
|
+
data: {id: last_message_id}
|
|
145
|
+
})
|
|
146
|
+
.done(function(messages) {
|
|
147
|
+
var insertHTML = '';
|
|
148
|
+
messages.forEach(function(message){
|
|
149
|
+
insertHTML = buildHTML(message);
|
|
150
|
+
$('.messages').append(insertHTML);
|
|
151
|
+
$('.messages').animate({ scrollTop: $('.messages')[0].scrollHeight});
|
|
152
|
+
})
|
|
153
|
+
})
|
|
154
|
+
.fail(function() {
|
|
155
|
+
alert('自動更新に失敗しました！');
|
|
156
|
+
});
|
|
157
|
+
}
|
|
158
|
+
};
|
|
159
|
+
setInterval(reloadMessages, 5000);
|
|
160
|
+
});
|
|
161
|
+
```
|
|
162
|
+
[3]このapi/index.controller.rbが始まります。
|
|

|
+
```Rails
|
|
164
|
+
class Api::MessagesController < ApplicationController
|
|
165
|
+
def index
|
|
166
|
+
group = Group.find(params[:group_id])
|
|
167
|
+
last_message_id = params[:id].to_i
|
|
168
|
+
@messages = group.messages.includes(:user).where("id > #{last_message_id}")
|
|
169
|
+
end
|
|
170
|
+
end
|
|
171
|
+
```
|
|
172
|
+
|
|
173
|
+
[#]こちらがconfig/routes.rbになります。

|
175
|
+
Rails.application.routes.draw do
|
|
176
|
+
devise_for :users
|
|
177
