我正在启动一个新的 Rails 3.2.6 应用程序。当我尝试查看新的嵌套表单时，我的嵌套路由失败。我将首先显示错误，然后显示所有涉及的代码。
尝试访问的 URL：http://localhost:3000/reports/1/expenses/new
No route matches {:action=>"show", :controller=>"expenses", :report_id=>#<Report id: 1, name: "Test Report", created_at: "2012-06-07 21:58:37", updated_at: "2012-06-07 21:58:37">}
路线.rb
resources :reports do
resources :expenses
end
费用_控制器.rb
def new
@report = Report.find(params[:report_id])
@expense = @report.expenses.new
end
意见/费用/new.html.haml
%h1 New Expense
= render 'form'
意见/费用/_form.html.haml
= form_for [@report, @expense] do |f|
这是我试图点击的链接：
= link_to 'New Expense', new_report_expense_path(@report)
当我明确调用新操作时，我无法弄清楚为什么它试图访问 show 操作。
耙子路线
