我有一个带有时间属性的模型。我想检查时间不能为空(更好的选择可能是检查输入是否为时间,但我不知道如何处理)。我试过这个验证:
# id :integer not null, primary key
# school_class_id :integer
# meeting_time :time
class Meeting < ActiveRecord::Base
validates :meeting_time,
:presence => { :message => "can't be empty!" }
end
然后我尝试在规范中检查这一点,但失败了(空闲时间可以,但不应该)。我做错了什么?
规格:
# id :integer not null, primary key
# school_class_id :integer
# meeting_time :time
require 'spec_helper'
describe Meeting do
before(:each) do
@class = FactoryGirl.create( :school_class )
@attr_meeting = {
:meeting_theme => 'Text is here',
:meeting_date => "#{Date.today}",
:meeting_time => "#{Time.now}",
:meeting_room => '1234'
}
end
describe "Validations" do
describe "Rejection" do
it "should reject blank time" do
wrong_attr = @attr_meeting.merge( :meeting_time => " " )
@class.meetings.build( wrong_attr ).should_not be_valid
end
end
end
end
错误:
Meeting Validations Rejection should reject blank time
Failure/Error: @class.meetings.build( wrong_attr ).should_not be_valid
expected valid? to return false, got true
