我正在尝试在has_many关联上的accepts_nested_attributes_for上测试{:_destroy =“1”}属性。
我已经将它用于has_one关联,但我无法弄清楚如何为has_many做这件事。
寻求建议!谢谢^^本
describe "nested attributes" do
describe "cell phone" do # the has_one association
it "accepts nested cell phone" do
contact = FactoryGirl.create(:contact)
contact.build_cell_phone(FactoryGirl.build(:cell_phone, :contact => contact).attributes)
lambda {
contact.save
}.should change(CellPhone, :count).by(1)
end
it "allows destroy attribute" do
contact = FactoryGirl.create(:contact)
cell_phone_attributes = FactoryGirl.build(:cell_phone, :contact => contact).attributes
contact.build_cell_phone(cell_phone_attributes)
contact.save
contact.cell_phone.should be_kind_of(CellPhone)
cell_phone_attributes.merge({:_destroy => "1"})
lambda {
contact.cell_phone_attributes = cell_phone_attributes
}.should change(CellPhone, :count).from(1).to(0)
end
it "rejects a cell phone with a blank number" do
contact = FactoryGirl.create(:contact)
contact.build_cell_phone(FactoryGirl.build(:cell_phone, :contact => contact, :number => "").attributes)
lambda {
contact.save
}.should_not change(CellPhone, :count)
end
it "rejects a cell phone with a blank cell provider" do
contact = FactoryGirl.create(:contact)
contact.build_cell_phone(FactoryGirl.build(:cell_phone, :contact => contact, :cell_provider_id => "").attributes)
lambda {
contact.save
}.should_not change(CellPhone, :count)
end
end
describe "jobs" do # the has_many association
it "accepts nested jobs" do
contact = FactoryGirl.create(:contact)
contact.jobs_attributes = 3.times.collect { FactoryGirl.build(:job, :contact => contact).attributes }
lambda {
contact.save
}.should change(Job, :count).by(3)
end
xit "allows destroy attribute" do # TODO skipped test
contact = FactoryGirl.create(:contact)
jobs_attributes = 3.times.collect { FactoryGirl.build(:job, :contact => contact).attributes }
contact.jobs_attributes = jobs_attributes
contact.save
contact.jobs.count.should == 3
# these are the old jobs_attributes, there is no jobs_attributes getter method on Contact!
jobs_attributes = jobs_attributes.each.collect { |hash| hash.merge({:_destroy => "1"}) }
lambda {
# this doesn't work, the attributes are from before the jobs were created
contact.jobs_attributes = jobs_attributes
contact.save
}.should change(Job, :count).from(3).to(0) # this fails, Job.count == 3 after the test
end
end
end
答案 0 :(得分:0)
您是否将:allow_destroy => true
选项传递给accepts_nested_attributes_for
?
应该看起来像:
class Contact
accepts_nested_attributes_for :jobs, :allow_destroy => true
end
