我间歇性地(在各种项目上)遇到了rspec重新加载ActiveRecord对象然后清除关联对象的问题。
“应该”工作的失败规范的示例如下(忽略测试的“优点”,这是一个简化示例):
# Message has_many :message_attachments
# MessageAttachment belongs_to :message
describe Message, 'instance' do
before(:each) do
@it = Factory(:message)
(1..3).each do
@it.message_attachments << Factory(:message_attachment, :message => @it)
end
end
it 'should order correctly' do
# This test will pass
@it.message_attachments.collect(&:id).should == [1, 2, 3]
end
it 'should reorder correctly' do
@it.reorder_attachments([6, 4, 5])
@it.reload
# @it.message_attachments is [] now.
@it.message_attachments.collect(&:id).should == [6, 4, 5]
end
end
答案 0 :(得分:0)
奇怪的是,为了解决这个问题,我必须使用已定义的父对象创建关联对象,并将附加到父对象的集合中:
describe Message, 'instance' do
before(:each) do
@it = Factory(:message)
(1..3).each do
ma = Factory(:message_attachment, :message => @it)
@it.message_attachments << ma
ma.save
end
end
it 'should order correctly' do
@it.message_attachments.collect(&:id).should == [1, 2, 3]
end
it 'should reorder correctly' do
@it.reorder_attachments([6, 4, 5])
@it.reload
@it.message_attachments.collect(&:id).should == [6, 4, 5]
end
end
