我有一个groups#new
视图。登录current_user后,将允许他们创建一个组。
我的Groups#new视图:当前用户的隐藏字段工作正常,但是我需要将角色= groupleader分配给该当前用户。
<div>
<%= fields_for :membership do %>
<%= hidden_field_tag "user_id", current_user.id %>
<%= hidden_field_tag "role", "groupleader" %>
<% end %>
</div>
<div class="field">
<%= f.label :title %><br />
<%= f.text_field :title %>
</div>
<div class="field">
<%= f.label :description %><br />
<%= f.text_area :description %>
</div>
<div class="actions">
<%= f.submit %>
</div>
<% end %>
然后在我的groups#create操作中:
def create
@group = Group.new(params[:group])
@membership = current_user.memberships.build(:group_id => params[:group_id])
这正在建立成员资格,但不影响角色。
我的模型如下:
class Group < ActiveRecord::Base
has_many :memberships, :dependent => :destroy
has_many :users, :through => :memberships
accepts_nested_attributes_for :users
class User < ActiveRecord::Base #Built with Devise Gem
has_and_belongs_to_many :roles
has_many :memberships, :dependent => :destroy
has_many :groups, :through => :memberships
class Membership < ActiveRecord::Base
attr_accessible :user_id, :group_id
belongs_to :user
belongs_to :group
end
class Role < ActiveRecord::Base
has_and_belongs_to_many :users
end
- -编辑
这就是我在玩的东西。...由于我是通过表单发送角色参数的,
@membership = current_user.memberships.build(:group_id => params[:group_id], :role => params[:role])
这是日志中的内容:
Parameters: {"group"=>{"title"=>"Test group w/leader", "description"=>"test"}, "commit"=>"Create Group", "role"=>"groupleader", "authenticity_token"=>"+GCK8bJddObwKdCoiqI5QzlGRyuci8b5JxmgXbOjgsc=", "utf8"=>"✓", "user_id"=>"8"}
User Load (0.3ms) SELECT "users".* FROM "users" WHERE "users"."id" = 8 LIMIT 1
WARNING: Can't mass-assign protected attributes: role
显然,我有一个大规模分配问题。
最佳答案
您的成员资格模型没有groupleader的attr_accessible。这不能让我为什么它不起作用。
我也建议将其命名为group_leader_id
