我在我的控制器使用此：如何将这些Rails4参数白名单列表？

def step_params 
    params.require(@type.underscore.to_sym).permit( 
    :id, :name, :note, :position, :institution_id, :protocol_id, :sequence_id,:orientation_id, 
    step_item_attributes: [:id, :note, :name, :position, :institution_id, :sequence_id, :orientation_id, :_destroy ], 
    step_list_attributes: [:id, :note, :name, :position, :institution_id, :sequence_id, :orientation_id, :_destroy ]) 
end

而且看到这个在服务器日志与嵌套属性的表单后提交：

Processing by StepsController#create as HTML 
    Parameters: {"utf8"=>"✓", "authenticity_token"=>"Xm6oMMJ2PLXhHfKS1RkIzG5LrCUAY6vLOF+e9XHgBE4=", "step_list"=>{"name"=>"bob bob", "note"=>"", "step_items_attributes"=>{"1411264481612"=>{"name"=>"", "orientation_id"=>"1", "sequence_id"=>"1", "note"=>"a note", "_destroy"=>"false"}}}, "commit"=>"Create Step list", "type"=>"StepList"} 
    User Load (0.4ms) SELECT "users".* FROM "users" WHERE "users"."id" = 1 ORDER BY "users"."id" ASC LIMIT 1 
Unpermitted parameters: step_items_attributes 
    (0.1ms) begin transaction 
    SQL (0.7ms) INSERT INTO "steps" ("created_at", "institution_id", "name", "note", "updated_at") VALUES (?, ?, ?, ?, ?) [["created_at", "2014-09-21 01:54:49.736556"], ["institution_id", 18], ["name", "bob bob"], ["note", ""], ["updated_at", "2014-09-21 01:54:49.736556"]] 
    (37.5ms) commit transaction 
Redirected to http://localhost:3000/steps/54 
Completed 302 Found in 47ms (ActiveRecord: 38.7ms)

在我看来就像“不允许的参数：step_items_attributes”

...是问题所在。

为什么我的permit方法不允许step_items_attributes散列？我怎么能找出其他符号可能工作？

回答：

您允许的物品套装step_item_attributes但您试图通过step_items_attributes（物品）加上's'。所以这就是为什么你得到Unpermitted parameters: step_items_attributes
