Rails 嵌套属性未找到/不允许

Question

我一直在尝试将嵌套属性输入到我的数据库中，但无法使其正常工作。

我有这些参数：

def domain_register_whois_contact_parameters
  params.require(:domain).permit( whois_contacts_attributes: [:id, :first_name, :last_name, :street, :number, :postal_code, :city, :phone_number, :email_address, :company_type_id, :company_kvk, :company_name, :country_id])
end

这些输入参数：

{"utf8"=>"✓",
 "authenticity_token"=>"P4WTxAHKLgeRUQq60JvD/uMjo0s2BdMtqlBr1B6Z2hQ=",
 "domain"=>{"domain_name"=>"test.com",
 "whois_contacts_attributes"=>{"0"=>{"first_name"=>"Edward",
 "last_name"=>"Doe",
 "street"=>"Broadway",
 "number"=>"1",
 "postal_code"=>"1234AB",
 "city"=>"Amsterdam",
 "country_id"=>"205",
 "phone_number"=>"316123465",
 "email_address"=>"email@email.com",
 "company_name"=>"",
 "company_kvk"=>"",
 "company_type_id"=>""}},
 "nameserver_first"=>"ns1.dns.com",
 "nameserver_second"=>"ns2.dns.com"},
 "commit"=>"Register domain"}

我收到如下错误： param not found: whois_contacts_attributes

用谷歌搜索了很多例子，但没有用。

在我的模型中，我有：

accepts_nested_attributes_for :whois_contacts

我的看法：

<%= f.simple_fields_for :whois_contacts, @domain.whois_contacts.new do |wc| %>
    <%= wc.input :first_name, input_html: { placeholder: "John" } %>
    <%= wc.input :last_name, input_html: { placeholder: "Doe" } %>

    <%= wc.input :street, input_html: { placeholder: "Main street" } %>
    <%= wc.input :number, input_html: { placeholder: "1" } %>
    <%= wc.input :postal_code, input_html: { placeholder: "1234AB" } %>
    <%= wc.input :city, input_html: { placeholder: "Amsterdam" } %>

    <div class="form-group select required domain_country_country_name">
        <label class="select required form-label" for="domain_country_country_name">
            <abbr title="required">*</abbr> Country
        </label>
        <div class="controls">
            <%= wc.collection_select :country_id, Country.all, :id, :full_name, {}, {:class=>'select required form-control'} %>
        </div>
    </div>

    <%= wc.input :phone_number, input_html: { placeholder: "0612345678" } %>
    <%= wc.input :email_address, input_html: { placeholder: "doe@johndoe.com" } %>

    <h3>Company information</h3>
    <%= wc.input :company_name, hint: 'If you have a company, please enter the company name.', input_html: { placeholder: "Doe Inc." } %>
    <%= wc.input :company_kvk, hint: 'Enter Chamber of Commerce (Kvk) number', input_html: { placeholder: "12345678" } %>

    <div class="form-group select required domain_company_company_name">
        <label class="select required form-label" for="domain_company_companyname">
            <abbr title="required">*</abbr> Company
        </label>
        <div class="controls">
            <%= wc.collection_select :company_type_id, CompanyType.all, :id, :full_name, {}, {:class=>'select required form-control'} %>
        </div>
    </div>
<% end %>

Answer 1

有 3 件事我会做不同的事情。

1 在控制器中建立你的记录

def new
  @domain = Domain.new
  @domain.whois_contacts.build
end

2 同一方法调用的白名单

def domain_params
  params.require(:domain).permit(:domain_name, :nameserver_first, :nameserver_second, whois_contacts_attributes: [:id, :first_name, :last_name, :street, :number, :postal_code, :city, :phone_number, :email_address, :company_type_id, :company_kvk, :company_name, :country_id])        
end

3 调整表单以获得更好的构建语句

<%= f.simple_fields_for :whois_contacts do |wc| %>
  <%= wc.input :first_name, input_html: { placeholder: "John" } %>
  <%= wc.input :last_name, input_html: { placeholder: "Doe" } %>

  <%= wc.input :street, input_html: { placeholder: "Main street" } %>
  <%= wc.input :number, input_html: { placeholder: "1" } %>
  <%= wc.input :postal_code, input_html: { placeholder: "1234AB" } %>
  <%= wc.input :city, input_html: { placeholder: "Amsterdam" } %>

  <div class="form-group select required domain_country_country_name">
    <label class="select required form-label" for="domain_country_country_name">
      <abbr title="required">*</abbr> Country
    </label>
    <div class="controls">
      <%= wc.collection_select :country_id, Country.all, :id, :full_name, {}, {:class=>'select required form-control'} %>
    </div>
  </div>

  <%= wc.input :phone_number, input_html: { placeholder: "0612345678" } %>
  <%= wc.input :email_address, input_html: { placeholder: "doe@johndoe.com" } %>

  <h3>Company information</h3>
  <%= wc.input :company_name, hint: 'If you have a company, please enter the company name.', input_html: { placeholder: "Doe Inc." } %>
  <%= wc.input :company_kvk, hint: 'Enter Chamber of Commerce (Kvk) number', input_html: { placeholder: "12345678" } %>

  <div class="form-group select required domain_company_company_name">
    <label class="select required form-label" for="domain_company_companyname">
      <abbr title="required">*</abbr> Company
    </label>
    <div class="controls">
      <%= wc.collection_select :company_type_id, CompanyType.all, :id, :full_name, {}, {:class=>'select required form-control'} %>
    </div>
  </div>
<% end %>
