如何擺脫續集中的續集錯誤？

init文件：

require 'sequel' 
DB = Sequel.connect('sqlite://data.db') 

DB.drop_table?(:restaurants) 
DB.create_table :restaurants do 
primary_key :id 
String :name 
end 

DB.drop_table?(:category) 
DB.create_table :category do 
primary_key :id 
String :name 
end 


DB.drop_table?(:items) 
DB.create_table :items do 
primary_key :id 
foreign_key :restaurant_id 
foreign_key :category_name 
String :name 
Float :price 
end 

require_relative './restaurant' 
require_relative './categories' 
require_relative './item'

應用程序文件：

require_relative './models/init 

p = Category.create(:name => 'Pizza') 
c = Category.create(:name => 'Calazone') 
pa = Category.create(:name => 'Pasta') 
s = Category.create(:name => 'Salad') 
d = Category.create(:name => 'Dessert') 
dr = Category.create(:name => 'Drink') 
si = Category.create(:name => 'Side')`

但我收到此錯誤：

/home/ben/.rvm/gems/ruby-1.9.3-p385/gems/sequel-3.45.0/lib/sequel/model/base.rb:1780:in `block in set_restricted': method name= doesn't exist (Sequel::Error) 
    from /home/ben/.rvm/gems/ruby-1.9.3-p385/gems/sequel-3.45.0/lib/sequel/model/base.rb:1767:in `each'

    from /home/ben/.rvm/gems/ruby-1.9.3-p385/gems/sequel-3.45.0/lib/sequel/model/base.rb:156:in `create' 
    from app.rb:4:in `<main>'"

幫助請。

感謝

你不發表您的分類模式，但我猜它實際上沒有看類別表（可能的類別表）。您要麼將數據庫表重命名爲類別，要麼告訴您的類別模型使用類別表。如果不是這樣，你可能想發佈你的模型代碼。
