ruby-on-rails - rails 5 : validation of acceptance for a checkbox

Question

我有一个带有一些嵌套字段的注册表单，在此表单中我添加了一个服务条款复选框。

我正在尝试验证复选框是否被选中，如果没有则返回错误。

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

我确实有一个 bool 列，该列在帐户表中设置为默认值。

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

另外，我添加了 :agreement到允许的 Controller 参数。

这是表格:

   <%= 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 %>

但它返回表单错误 agreement must be accepted即使我确实接受了。任何想法我可能会错过ohere!

试试:validates :agreement, acceptance: {accept: true} , on: :create,
allow_nil: false
你不想:allow_nil => true如果您正在验证接受。
