Rails，使用集合模型在单个表单上一次更新多条记录

# app/controllers/records_controller.rb
class RecordsController < ApplicationController
  def edit
    @records = Record.all
  end

  def update
    @records = Record.all
    if @records.update(records_params)
      redirect_to records_path, notice: 'Records updated successfully.'
    else
      render :edit
    end
  end

  private

  def records_params
    params.require(:records).permit(records_attributes: [:id, :name, :value])
  end
end

# app/views/records/edit.html.erb
<%= form_with(model: @records, url: records_path, method: :patch) do |form| %>
  <% @records.each do |record| %>
    <%= form.fields_for(record) do |record_fields| %>
      <div class="record">
        <%= record_fields.label :name %>
        <%= record_fields.text_field :name %>
        <%= record_fields.label :value %>
        <%= record_fields.text_field :value %>
      </div>
    <% end %>
  <% end %>
  <%= form.submit 'Update Records' %>
<% end %>
