【问题描述】:
我在尝试创建新限制或编辑限制(以下模型)时遇到此错误
Rails_admin/main#new 中的参数错误
显示 /Users/deini/.rvm/gems/ruby-2.0.0-p195/gems/rails_admin-0.4.9/app/views/rails_admin/main/_form_filtering_select.html.haml 其中第 11 行提出:
参数数量错误(0 表示 1+)
提取的源代码(第 11 行附近):(selected_id = field.selected_id)
selected_id = selected.send(field.associated_primary_key)
selected_name = selected.send(field.associated_object_label_method)
else
selected_id = field.selected_id
selected_name = field.formatted_value
end
系统.rb
class System < ActiveRecord::Base
has_many :attachments
has_many :limitations
has_many :companies, :through => :limitations
accepts_nested_attributes_for :attachments
accepts_nested_attributes_for :companies
attr_accessible :conf_type, :version, :hardware_type, :name, :attachments_attributes, :company_ids, :companies_attributes
rails_admin do
list do
exclude_fields :created_at, :updated_at
end
end
end
公司.rb
class Company < ActiveRecord::Base
belongs_to :distributor
has_many :users, dependent: :destroy
has_many :limitations
has_many :systems, :through => :limitations
accepts_nested_attributes_for :limitations
attr_accessible :distributor_id, :name, :system_ids, :email, :limitations_attributes
rails_admin do
list do
exclude_fields :custom_url, :created_at, :updated_at
end
edit do
exclude_fields :custom_url, :users
end
end
end
limitation.rb
class Limitation < ActiveRecord::Base
belongs_to :company
belongs_to :system
attr_accessible :company_id, :system_id, :version_limit
end
我没有修改我的 rails_admin 中的任何内容,对我做错了什么有任何想法吗?
【问题讨论】:
-
selected_id 方法的签名是什么?
-
很抱歉,您所说的 selected_id 方法的签名是什么意思,我怎样才能得到它?
-
行 'selected_id = field.selected_id' 将局部变量设置为在对象 'field' 上调用方法 'selected_id' 时返回的值。错误说你没有足够的参数 {wrong number of arguments (0 for 1+)} 所以我想知道 selected_id 方法需要什么参数。
