Rails 5:验证复选框的接受程度

Question

我有一个带有一些嵌套字段的注册表单,在这个表单中我添加了一个服务条款的复选框.

我正在尝试验证何时选中复选框,如果没有则返回错误.

 validates_acceptance_of :agreement, :allow_nil => true, :accept => true, :on => :create

我有一个布尔列,在accounts表中设置为默认值.

add_column :accounts, :agreement, :boolean, default: false

此外,我已添加:agreement到允许的控制器参数.

这是形式:

   <%= form_for(resource, as: resource_name, url: registration_path(resource_name)) do |f| %>
    <div class="centerList">
      <div id="error_explanation">
        <%= devise_error_messages! %></div>
    </div>

      <div class="form-group">
        <span class="asterisk_input"></span>
        <%= f.email_field :email, autofocus: true, placeholder: "email", :class=>"form-control" %>
      </div>

      <div class="form-group">
        <span class="asterisk_input"></span>
        <%= f.password_field :password, placeholder: "password", autocomplete: "off", :class=>"form-control" %>
      </div>

      <div class="form-group">
        <span class="asterisk_input"></span>
        <%= f.password_field :password_confirmation, placeholder: "confirm password", autocomplete: "off", :class=>"form-control"  %>
      </div>

      <%= f.fields_for :account do |form| %>


      <div class="form-group">
        <span class="asterisk_input"></span>
        <%= form.text_field :street, placeholder: "street", :class=>"form-control" %>
      </div>

      <div class="form-group">
        <span class="asterisk_input"></span>
        <%= form.text_field :city, placeholder: "city", :class=>"form-control"  %>
      </div>

      <div class="form-group">
        <span class="asterisk_input"></span>
        <%= form.text_field :state, placeholder: "state", :class=>"form-control" %>
      </div>

      <div class="form-group">
        <span class="asterisk_input"></span>
        <%= form.text_field :zip_code, placeholder: "zip code", :class=>"form-control" %>
      </div>

      <div class="form-group">
        <span class="asterisk_input"></span>
        <%= form.country_select :country, ["US"], {}, { :class => "form-control", :id=>"sign-frm-input" } %>
      </div>

      <div class="form-group">
          <%= form.check_box :agreement %> I agree to the <%= link_to 'Terms', term_path(:id=>1) %>.
      </div>

<% end %>
      <div class="form-group">
        <%= f.submit "Sign up", :class=>'btn btn-primary' %>
  <% end %>

但agreement must be accepted即使我接受它,它也会返回表单错误.任何想法我可能会遗漏的东西!

Answer 1

尝试: validates :agreement, acceptance: {accept: true} , on: :create, allow_nil: false

:allow_nil => true如果你要验证接受,你不想要.

Answer 2

您可以更改模型验证并对其进行测试。

validates :agreement, inclusion: {in: [true]}

或者您可以使用其他验证

validates :agreement, acceptance: { accept: true }
