常规表格

Question

我已经使用Cocoon添加了嵌套表单，但是没有发送属性而且没有保存任何内容。到目前为止，我尝试过复数/单数但没有运气。到目前为止我能得到的最好的是它在我以单数制作f.simple_fields_for时发送参数但是后来仍然只发送了1个（只有第一个添加的）并且我得到了未经许可的参数vacancyschedule＆＃39;，但据我所知，我遵循明确命名的文档。任何帮助表示赞赏。

我的设置：

模型

vacancy.rb

has_many :vacancyschedules, dependent: :destroy
accepts_nested_attributes_for :vacancyschedules, reject_if: :all_blank, allow_destroy: true

vacancyschedule.rb

belongs_to :vacancy

控制器

def vacancy_params
  params.require(:vacancy).permit(:address, :name, :street, :city, :zip, :country, :description, :jobtype_id, :recruiter_id, :start_date, :end_date, :start_hour, :end_hour, :skill_id, :wage_cents, :tag_list, :jobterm_id, vacancyschedule_attributes: [:start_date, :end_date, :start_hour, :end_hour, :address, :_destroy, :id])
end

常规表单

 = simple_form_for @vacancy do |f| 
   ... regular fields that are saving correctly ...
   .vacancyschedules
     = f.simple_fields_for :vacancyschedules do |vacancyschedule|
       =render "vacancyschedule_fields", :f, :vacancyschedule
    .links
      =link_to_add_association 'add schedule', f, vacancyschedules

部分

.nested-fields
  .field
    =f.input :start_hour, as: :time
  .field
    =f.input :end_hour, as: :time

  =link_to_remove_association "", f

编辑如上所述，

当我执行simple_fields_for：vacancyschedule时，我得到了一些参数（尽管它只是第一个参数，如果添加了更多的表格则会忽略）

 Parameters: {"utf8"=>"✓", "authenticity_token"=>"iF/6usHuIszbWH+JCERMZHKPGQu59VrLePlyR1Xea8hqlTbGdgCRJmG9bwh
XlCczK7xLK3JW96vkngwY5PzYJg==", "vacancy"=>{"recruiter_id"=>"2", "name"=>"", "address"=>"", "description"=>"", "jobtype_id"=>"", "jobterm_id"=>"", 
"wage_cents"=>"", "vacancyschedule"=>{"start_hour(1i)"=>"2015", "start_hour(2i)"=>"12", "start_hour(3i)"=>"9", "start_hour(4i)"=>"09", 
"start_hour(5i)"=>"00", "end_hour(1i)"=>"2015", "end_hour(2i)"=>"12", "end_hour(3i)"=>"9", "end_hour(4i)"=>"17", "end_hour(5i)"=>"00", 
"start_date"=>"1/1/1"}}, "commit"=>"Create Vacancy"}
 Unpermitted parameter: vacancyschedule

当复数时，没有发送任何内容..

更新2

在我的vacancycontroller中新建和创建方法

  def new
    @vacancy = Vacancy.new
    # @vacancyschedules = @vacancy.vacancyschedules
  end

  def create
    @vacancy = Vacancy.create(vacancy_params)
    # Vacancyschedule.create(vacancyschedule_params)
    redirect_to show_created_vacancy_path(@vacancy)
  end

据我所知，只有新的和创造的母亲＆＃34;模型是必要的。我之前也尝试过在那里添加计划而没有成功进行测试..

Answer 1

我想错误地定义渲染部分：

常规表格

$productIds = [1 => [
     'created_by' => 1,
     'updated_by' => 1
],3 => [
     'created_by' => 1,
     'updated_by' => 1
],5 => [
     'created_by' => 1,
     'updated_by' => 1
],6 => [
     'created_by' => 1,
     'updated_by' => 1
]];

Answer 2

#vacancy.rb:
has_many :vacancyschedules, dependent: :destroy
accepts_nested_attributes_for :vacancyschedules,
  reject_if: :all_blank,
  allow_destroy: true

和vacancyschedule.rb：

#vacancyschedule.rb:
belongs_to :vacancy

在空缺控制器中：

#vacancy_controller.rb:
def create
  @vacancy = Vacancy.new(vacancy_params)
  if @vacancy.save
    redirect_to :back, notice: "vacancy successfully created."
  else
    render :new
  end
end

private
def vacancy_params
  params.require(:vacancy).permit(:address, :name, :street, :city..., vacancyschedules_attributes: [:start_date, :end_date, :start_hour...])
end

在您看来：

#_form.html.haml
= simple_form_for @vacancy do |f| 
  ... regular fields that are saving correctly ...
  .vacancyschedules
    = f.simple_fields_for :vacancyschedules do |vacancyschedule|
      =render "vacancyschedule_fields", f: vacancyschedule
    .links
      =link_to_add_association 'add schedule', f, vacancyschedules

#vacancyschedule_fields.html.haml
.nested-fields
  .field
    =f.input :start_hour, as: :time
  .field
    =f.input :end_hour, as: :time

  =link_to_remove_association "X", f

这应该适合你。

Answer 3

您的强参数定义（在此处发布）是错误的：您编写vacancyschedule_attributes（单数）并且必须匹配关联，因此它应该是vacancyschedules_attributes。

完全不相关的旁注：我更喜欢类名VacancySchedule，因此更喜欢关联名vacancy_schedules。这更容易阅读。

Answer 4

首先，谢谢大家的帮助。

我发现代码本身并没有错。出于某种原因，周围的div正在搞乱cocoon提供的javascript。我剥离了所有的div /样式，它正确地提交和保存。对我来说，下一个挑战是逐步添加样式并查看问题发生的位置。
