これらは私の 2 つのモデルで、何も複雑ではありません。
class Invoice
belongs_to :user
has_many :invoice_line_items
accepts_nested_attributes_for :invoice_line_items, allow_destroy: true
end
class InvoiceLineItem
belongs_to :invoice
end
これは、ネストされた属性用に変更された simple_form です。
<%= simple_form_for(@invoice) do |f| %>
<%= f.error_notification %>
<div class="form-inputs">
<%= f.input :adress_sender %>
<%= f.input :adress_recipient %>
<%= f.input :status %>
<%= simple_fields_for :invoice_line_items do |invoice_line_items_form| %>
<%= invoice_line_items_form.input :description %>
<%= invoice_line_items_form.input :price %>
<%= invoice_line_items_form.input :amount %>
<% end %>
</div>
<div class="form-actions">
<%= f.button :submit %>
</div>
<% end %>
これは、Rails の公式ドキュメントによるとコントローラーです。

def invoice_params
params.require(:invoice).permit(:adress_sender, :adress_recipient, :status, :user_id, :customer_id, invoice_line_items: [:description, :price, :amount])
end
end
請求書の項目が作成されています。ただし、作成日と更新日とIDだけです。説明、価格、金額などのすべてのフィールドが空です。また、allow_destroy が機能していないようです。残念ながら、サーバーコンソールにエラーはありません:/
提案されているように、作成のコンソール ログを編集します。
