我有下面的代碼,以我的發票模型中創建一個嵌套模型(invoice_line_items):使用nested_form自舉表中沒有定型正常
= nested_form_for @invoice, mutipart: true, class: "form-horizontal" do |f|
...
%table.table.table-bordered{:id => "line-items"}
%thead
%tr
%th
%th Description
%th Quantity
%th Rate
%tbody
%tr
= f.fields_for :invoice_line_items do |line_item|
%td= line_item.link_to_remove "X"
%td= line_item.text_field :description
%td= line_item.text_field :quantity, :class => "input-mini"
%td= line_item.text_field :rate, :class => "input-mini"
= f.link_to_add "Add", :invoice_line_items, :data => { :target => "#line-items" }
我有兩個問題:1)當我添加一個新行通過點擊「添加」....它與表格格式不匹配,並且不會插入到表格中。我嘗試了一切來讓它起作用,但它卻沒有。我也嘗試添加ryanb在他的寶石文檔中提到的「:target」。 2)我希望最初有3個invoice_line_items爲發票頁面上的用戶準備好,但我不知道如何執行此操作。
編輯:我現在有點不同了,因爲我一直在玩它。我不認爲我做是正確的還是,但現在它創建了一個新的形式,每次我點擊「添加」:
.row-fluid
= f.fields_for :invoice_line_items, :wrapper => false do |line_item|
%table.table.table-bordered#tasks
%thead
%th
%th Description
%th Quantity
%th Rate
%tr.fields
%td= line_item.link_to_remove "X"
%td= line_item.text_field :description
%td= line_item.text_field :quantity, :class => "input-mini"
%td= line_item.text_field :rate, :class => "input-mini"
.row-fluid
= f.link_to_add "Add", :invoice_line_items, :data => { :target => "#tasks" }
