Rails 3脚本创建模型

Question

我想创建一个跑步者脚本来建立模型。模型是这样的：

class Day < ActiveRecord::Base 
    has_many :slots 
    attr_accessible :available, :day_date, :venue 
end 

class Slot < ActiveRecord::Base 
    belongs_to :day 
end 

我想使每天有9个插槽的空白天数为100。这是亚军脚本load_days.rb

Day.transaction do 
    (1..100).each do |i| 
    days = Date.today+i 
    Day.create(:available => "Available", :venue => "Pitch_1", :day_date => days) 
    (1..9).each to |j| 
     hours = days.hours+j 
     id = Day.id 
     Slot.create (:time_slot => hours , :day_id => id) 
    end 
end 
end 

我收到以下错误： 脚本/ load_days.rb：8：语法错误，意想不到的tASSOC，期待tCOLON2或 '[' 或 '' Slot.create（：TIME_SLOT =>小时：day_id => ID）

Answer 1

您在天类，而不是创建的对象日.ID调用，这应该工作：

Day.transaction do 
    (1..100).each do |i| 
    days = Date.today+i 
    day = Day.create(:available => "Available", :venue => "Pitch_1", :day_date => days) 
    (1..9).each to |j| 
     hours = days.hours+j 
     id = day.id 
     Slot.create (:time_slot => hours , :day_id => id) 
    end 
end 
end
