如何将boolean值设置为rails 4形式的单选按钮

Question

我试图将一个真/假值设置为rails 4中表单中的单选按钮.我在stackoverflow上发现了一个帖子,并相应地实现了我的单选按钮,但我总是将其作为值.

我的代码

  <div><%= label :access_rights, 'Read Only', :value => "false" %></div>
  <%= f.radio_button :access_rights, "Read Only", :checked => true , false%></div>
  <div><%= label :access_rights, 'Read and Write', :value => "true" %></div>
  <%= f.radio_button :access_rights, "Read and Write", true %>

是否有不同的方法为rails 4中的单选按钮设置值？

编辑:

在我的控制器中

def access_params
  params.require(:accessor).permit(:email, :access_rights)
end

参数:

{"utf8"=>"?",
 "authenticity_token"=>"t/da2RRBi4KsyndnHx4WNZLoOHu9DVlAWtl/59NPiMc=",
 "accessor"=>{"accessor_id"=>"email",
 "access_rights"=>"Read and Write"},
 "commit"=>"Grant Permission"}

我相信其他答案的标签不会正常工作.以下是更正标签的示例.

<div>
  <%= label :access_rights, "Read Only", value: false %>
  <%= f.radio_button :access_rights, false, :checked => true, :value => false %>
</div>

<div>
  <%= label :access_rights, "Read and Write", value: true %>
  <%= f.radio_button :access_rights, true, :value => true%>
</div>
