Rails, 表单路径

Question

我正在尝试使用 simple_form

在一页中创建多个课程

路线看起来像这样

  resources :schools do
    resources :groups do
      resources :lessons, only: [:new, :create, :destroy]
    end
  end

      school_group_lessons POST   /schools/:school_id/groups/:group_id/lessons(.:format)     lessons#create
   new_school_group_lesson GET    /schools/:school_id/groups/:group_id/lessons/new(.:format) lessons#new

表格目前看起来像这样（尝试了很多变体，但我总是出错）

= simple_form_for school_group_lesson_path [school_id: 1, group_id: 1, Lesson.new]. remote: true, method: :post do |f|

我得到的错误是

Can't assign to true 1, Lesson.new]. remote: true, method: :post do |f|; ^ /home/panda/workspace/Schooled/app/views/lessons/_form.html.slim:18: syntax error, unexpected keyword_end, expecting end-of-input _concat(("".freeze)); end; @output_buffer.safe_concat(( ^

这并没有给我任何解决问题的线索... 谁能告诉我我做错了什么：？谢谢！

Answer 1

我可以为您指出一些错误

您在 [school_id: 1, group_id: 1, Lesson.new] 之后有一个 点 (.)，它应该是一个 逗号(,)

这是错误的[school_id: 1, group_id: 1, Lesson.new]。您应该将 school 和 group 的实例作为参数连同 Lesson.new

表单路径乱七八糟。应该是

= simple_form_for school_group_lessons_path(@school_instance,@group_instance,Lesson.new), remote: true, method: :post do |f|

或

= simple_form_for [@school_instance,@group_instance,Lesson.new], remote: true, method: :post do |f|

还要注意 school_group_lesson_path 应该是 school_group_lessons_path

最后确保在 controller#action

中定义所需的 school 和 group 实例

Answer 2

您在这一行中使用了句点而不是逗号：

= simple_form_for school_group_lesson_path [school_id: 1, group_id: 1, Lesson.new]. remote: true, method: :post do |f|

尝试：

= simple_form_for school_group_lesson_path(school_id: 1, group_id: 1, Lesson.new), remote: true, method: :post do |f|

注意：simple_form_for 的正确用法类似于：

simple_form_for @lesson do |f|
  f.input ....
end
