邀请与组织(many:1)和用户(many:many-through)关联。这在发展中起作用我可以创建一个新的邀请,它会发送一封带有邀请的电子邮件。此邀请的值为person_one_id
、person_two_id
和organization_id
。Person-one和Person-two是用户模型中的用户这在开发中有效,控制台可以正确返回Invitation.first.organization
、Invitation.first.person_one
和Invitation.first.person_two
的记录。
问题是我的邮件测试。尽管从fixtures加载的邀请的值为person_one_id
、person_two_id
和organization_id
,但如果在调试器中调用invitation.organization
、invitation.person_one
或invitation.person_two
,它将返回nil
。
有人知道我的测试代码出了什么问题吗?
邮递员:
def invitation(invitation)
@invitation = invitation
@organization = invitation.organization # This returns nil even though invitation has a value for organization_id
...etc...
end
固定装置:
invitation_one:
person_one: users(:one) # Loads this person from users fixtures.
person_two: users(:archer)
organization: organizations(:one) # Loads from organizations fixtures.
message: I am pleased to invite you1
邮件测试:
test "invitation" do
@invitation = invitations(:invitation_one)
mail = InvitationMailer.invitation(@invitation)
# Produces a "NoMethodError: undefined method `id' for nil:NilClass" error since a.o. invitation.organization is nil.
...etc...
end
在加载fixture之后,我在测试文件中添加了调试器调试器对
@invitation
的响应为:<Invitation id: 749093126, person_one_id: 41652760, person_two_id: 976142315, organization_id: 118162230, email: nil, message: "I am pleased to invite you1", created_at: "2015-07-05 09:06:23", updated_at: "2015-07-07 12:27:19">
这证明了关联(
person_one_id
、person_two_id
和organization_id
)具有价值。然而,调试器用nill响应@invitation.organization
,对@invitation.person_one
和@invitation.person_two
也一样。 最佳答案
结果问题出在固定装置上。要为我需要使用的装置创建关联,请执行以下操作:
invitation_one:
person_one: one
person_two: archer
organization: one
message: I am pleased to invite you1
