已經一個月試圖解決問題的一見鍾情並不是很複雜: 有3個模型 - 團隊,用戶和team_user(has_namy:through) 以編輯和新團隊的形式做動態添加這個團隊的成員。Rails 5 - 如何在編輯表單中動態添加嵌套字段?
場景:
- 用戶談到球隊新形式
- 表示球隊的名稱
- 名稱字段中選擇用戶(團隊成員)後
- 單擊添加成員按鈕
- 確認某個成員後,在文本字段中的團隊名稱字段後面添加+刪除按鈕
- 從選擇器刪除他(會員)的名字(因爲它已經是一個團隊成員)
- 在selite選擇下一個用戶,然後單擊添加成員按鈕
- 按提交按鈕,保存新的團隊和團隊成員
難點:
- 我試圖通過寶石繭做的,但它是不可能使不同parshaly選擇用戶要添加到它(選擇),並已添加的成員(全名 - 文本)
- 如果通過<%= from_for ... remote:true%>以及控制器teams_controller中的單獨控制器或新操作,它將是兩種形式的嵌套(形狀和表單團隊team_user)和他的第二個提交按鈕。據我所知,附件表格不是gud。
- 變化形式(改變球隊的名字,並添加/刪除團隊成員只計數點擊保存基本提交表單隊後)
