循環創建JSON對象

Question

只是想循環通過我的故事模式..和創建JSON對象並將其插入到打電話和發..但我不知道如何循環通的故事..

我已經做了這一點：

​​

我試圖TI插入循環這個JSON對象

"message" => { 
    "attachment" => { 
     "type" => "template", 
     "payload" => { 
     "template_type" => "generic", 
     "elements" => [{this is the array}] 
     } 
    } 
} 

與多個故事中的數組應該是這樣的：

[ 
    { 
    "title" => "title....1", 
    "image" => "image....1" 
    }, 
    { 
    "title" => "title....2", 
    "image" => "image....3" 
    } 
    .... 
] 

Answer 1

嘗試以下操作：

@stories = Story.where(newsletter_id: current_user.selected_newsletter) 
       .select(:title, 'image_url as image').as_json(except: :id) 

然後：

{ 
    "message" => { 
    "attachment" => { 
     "type" => "template", 
     "payload" => { 
     "template_type" => "generic", 
     "elements" => @stories 
     } 
    } 
    } 
}
