我在創建一個嵌套表單時遇到問題，該表單可以使用nested_form和simple_form插件與以下域模型正常工作。我想我正在構造不正確的表單，或者是attr_accessible和accept_nested_attributes_for調用。nested_form問題，幾個級別深層的模型關聯
我有這樣的域模型與以下關聯：
company.rb
class Company < ActiveRecord::Base
has_one :subscription
attr_accessible :name, :subscription_attributes, :cycles_attributes, :payments_attributes
accepts_nested_attributes_for :subscription
end
subscription.rb
class Subscription < ActiveRecord::Base
belongs_to: company
has_many :cycles
attr_accessible :company_id, :cycles_attributes, :payments_attributes
accepts_nested_attributes_for :cycles
end
cycle.rb
class Cycle < ActiveRecord::Base
belongs_to :subscription
has_many :payments
attr_accessible :payments_attributes
accepts_nested_attributes_for :payments
end
付款。 rb
class Payment < ActiveRecord::Base
belongs_to :cycle
end
我的看法是這樣的：
<%= simple_nested_form_for company do |f| -%>
<%= f.input :name %>
<%= f.fields_for :subscription do |s| %>
#assorted fields for subscription
<%= s.fields_for :cycles do |c| %>
#assorted fields for cycle
<%= c.link_to_remove "[ - ] Erase Cycle" %>
<%= c.fields_for :payments do |p| %>
#assorted fields for payments
<%= p.link_to_remove "[ - ] Erase Payment" %>
<% end %>
<%= c.link_to_add "[ + ] New Payment", :payments %>
<% end %>
<%= s.link_to_add "[ + ] New Cycle", :cycles %>
<% end %>
公司控制器：
def new
@company = Company.new
@company.build_subscription
@categories = Category.find(:all)
respond_with @company
end
def create
@company = Company.new(params[:company])
if @company.save
flash[:notice] = "Success"
else
flash[:error] = "Error #{@company.errors.full_messages}"
end
respond_with @company
end
當然，我簡化了意見和材料，還有一些驗證和領域我沒有顯示，但這些都不是問題。 當我提交我得到一些奇怪的錯誤形式，基本上所有信息在PARAMS通過，但它不是正確的嵌套：/
Parameters: {"utf8"=>"✓", "authenticity_token"=>"57wgXJinL6kql0F9CxShKpf11RhdMfqXnb6y8K/pDg0=",
"company"=>{"name"=>"asdf12",
"subscription_attributes"=>{
"cycles_attributes"=>{
"0"=>{"plan_id"=>"1", "amount"=>"123", "months"=>"12", "_destroy"=>"false"}
},
"0"=>{
"0"=>{
"payments_attributes"=>{
"new_1329843584974"=>{"payment_type"=>"Efectivo", "amount"=>"123", "receipt_number"=>"1231", "note"=>"asdf asdf", "_destroy"=>"false"
}
}
}
}
}
}, "commit"=>"Save"}
WARNING: Can't mass-assign protected attributes: 0
的錯誤是：
@messages={:"subscription.cycles.subscription"=>["can't be blank"],
:"subscription.cycles.payments"=>["can't be blank"]}
也有一些是如何將屬性傳遞給應用程序，我的猜測是，當我點擊新的付款按鈕時，它會在窗體「外部」創建......有沒有人遇到類似的東西？
