我从一个链接调用这个 js:
function createNewTopLevelEntry(){
var user_id = $("#user").val();
var header = prompt("Enter the name");
$.ajax( '/users/' + user_id + '/entries', {
data: {
entry: { header: header,
user: user_id } },
type: 'POST',
cache: false,
dataType: 'json',
success: displayTopLevelEntries
});
}
它击中了这个控制器:
def create
@entry = Entry.new(params[:entry])
respond_to do |format|
if @entry.save
format.html { redirect_to @entry, notice: 'Entry was successfully created.' }
format.json { render json: @entry, status: :created, location: @entry }
else
format.html { render action: "new" }
format.json { render json: @entry.errors, status: :unprocessable_entity }
end
end
end
这是服务器上的响应:

entry_url 是什么?它为什么要找它?我需要在模型中包含一些东西吗?它只有用于变量的 attr_accessors。
class Entry < ActiveRecord::Base
attr_accessible :completed, :endtime, :header, :starttime, :starttimeset, :totaltime, :user, :text, :parent
end
这是我的路线文件:
Tasks::Application.routes.draw do
match '/users/:id/projects' => 'users#show_projects_for_user'
authenticated :user do
root :to => 'home#index'
end
root :to => "home#index"
devise_for :users
resources :users do
resources :entries
end
end
谢谢您的帮助。
