我有一个编辑视图,可以让我更新特定用户的角色。下面是代码,但仅供参考,当我在页面上取消勾选框时,我的控制器中的puts语句会正确地捕获到角色关联为false,并且可以在日志中进一步查看。
然而,在日志的后面,您可以看到角色被重新关联回“true”,我不确定为什么会这样!
如果未选中复选框,则希望将这些角色从用户中删除。 users/edit.html.erb:

<fieldset>
<%= form_for @user, :url => {action: "update"}, :html => { :class => 'user-role' } do |f| %>
<h1 class="h1-heading">User Roles</h1>
<p class="user-paragraph"> Check the boxes to grant different roles to <%= @user.first_name %> <%= @user.last_name %>:</p>
<%= f.label(:admin) do %>
<%= hidden_field_tag(:admin, 0) %>
<%= check_box_tag(:admin, 1, @user.has_role?(:admin)) %>
Administrator
<% end %>
<%= f.label(:member) do %>
<%= hidden_field_tag(:member, 0) %>
<%= check_box_tag(:member, 1, @user.has_role?(:member)) %>
Member
<% end %>
<%= f.submit class: 'btn btn-primary-dialog pull-right' %>
<% end %>
</fieldset>
users_controller.rb:
def update
@user = User.find(params[:id])
@customer = current_user.customer
@logged_in_user = User.find_by_email(current_user.email)
if params[:admin] == "1"
@user.grant(:admin)
elsif params[:admin] == "0"
@user.remove_role(:admin)
end
if params[:member] == "1"
@user.grant(:member)
elsif params[:member] == "0"
@user.remove_role(:member)
end
puts "NEW ROLES"
puts @user.has_role? :member
puts @user.has_role? :admin
if @user.update_attributes(params[:user])
puts "UPDATING USER"
puts @user.has_role? :member
puts @user.has_role? :admin
redirect_to '/users/show', :flash => { :alert => 'User was successfully updated.' }
end
end
end
日志:
如下所示,它返回“false”,然后在更新属性时再次将角色设置为“true”,我无法确定发生这种情况的原因或位置!
