[英]rspec controller test fails with argument error in model
I have this problem, i am testing my controllers POST method and i get this error: 我有这个问题,我正在测试我的控制器的POST方法,并且出现此错误:
ArgumentError:
Missing invite relation
I have form which is sent and with callback after_save other method is called which calls other method where constant is passed. 我有发送的形式,并带有after_save回调,调用了另一个方法,该方法调用传递常量的其他方法。 But called method calls validation which fails on that constant.
但是调用的方法将调用验证,该验证在该常量上失败。
Here is the snippets of code. 这是代码片段。 Model:
模型:
after_save :maintain_sender_attr
def maintain_sender_attr
self.affiliate_receivers.each do |count|
unless count.email == ""
send_email(count.email)
end
end
end
def send_email(to)
@resource_invite = InviteSender::NewInvite.new(self, to, CONTENT_TYPE_INVITE)
@resource_invite.body_html = prepare(@resource_invite.invite.body_html)
@resource_invite.send
end
def prepare body_html
context_objects.each {|key, value| body_html.gsub! "[#{key}]", value}
body_html
end
here is the constant: 这是常量:
NOTIFICATION_CONTENT_TYPES = [
CONTENT_TYPE_INVITE = 'referral_invite'
]
and here is where the error is raised: 这是引发错误的地方:
class InviteSender::Base
attr_accessor :missing_fields, :body_html, :invite, :owner, :to
# Initialize new sender instance
# @notification [Notification, String] notification or notification content_type
def initialize owner, to, invite
@owner = owner
@to = to
if invite.is_a? Invite
@invite = invite
else
@invite = Invite.find_by(content_type: invite)
end
validate
load_body_html_template
end
def validate
raise ArgumentError, "Missing owner relation" if @owner.nil?
raise ArgumentError, "Missing invite relation" if @invite.nil?
raise ArgumentError, "Missing to relation" if @to.nil?
raise NotImplementedError, "Missing #locale method" unless respond_to? :locale
end
lastly the test itself: 最后是测试本身:
describe "with valid attributes" do
it "creates new sender and there affiliated receivers" do
expect{
post :create, node_id: @node.id, locale: @node.locale, affiliate_sender: FactoryGirl.attributes_for(:affiliate_sender, :affiliate_receivers_attributes =>{"0"=>{"email"=>"test@test.com"}}), format: :json
}.to change(AffiliateSender, :count).by(1)
end
it "it return success json" do
post :create, node_id: @node.id, locale: @node.locale , affiliate_sender: FactoryGirl.attributes_for(:affiliate_sender, :affiliate_receivers_attributes =>{"0"=>{"email"=>"test@test.com"}}), format: :json
response.status.should eq(200)
end
end
I can't undesrtand what exactly goes wrong. 我无法取消错误到底是什么。 Constant is defined on
config/environment.rb
but it feels like constant is empty, because this error is raised if constant is empty! 常量是在
config/environment.rb
上定义的,但是感觉常量为空,因为如果常量为空,则会引发此错误! Do i have to stub or moch this constant? 我是否必须存根或移动该常数?
You are actually defining NOTIFICATION_CONTENT_TYPES as an array of 'Constants which get evaluated to their content'. 您实际上是在将NOTIFICATION_CONTENT_TYPES定义为“对其内容进行评估的常量”的数组。 This means that
这意味着
NOTIFICATION_CONTENT_TYPES # => ["referral_invite"]
So to access the right Constant you have to do: 因此,要访问正确的常量,您必须执行以下操作:
NOTIFICATION_CONTENT_TYPES[0]
Better would be to define it in a concise way: 最好以简洁的方式定义它:
NOTIFICATION_CONTENT_TYPES = { content_type_invite: 'referral_invite' }
And then you can access the right value with 然后,您可以使用
NOTIFICATION_CONTENT_TYPES[:content_type_invite]
