我正在按照 https://blog.engineyard.com/2014/getting-started-with-active-job 在 Rails 4.2 中实现 Active Job。但是在Resque中面临以下问题。错误显示:
Worker
ChickenSmitten.local:64238 on EMAIL at just now Retry or Remove
Class
ActiveJob::QueueAdapters::ResqueAdapter::JobWrapper
Arguments
---
job_class: PasswordResetJob
job_id: 35f70043-9a9b-4add-8700-a5f388350fb4
queue_name: email
arguments:
- bob@example.com
Exception
NoMethodError
Error
undefined method `email' for "bob@example.com":String
我的代码如下:
password_resets_controller.rb
def create
@user = User.find_by(email: params[:password_reset][:email].downcase)
if @user
@user.create_reset_digest
@user.send_password_reset_email
flash[:notice] = "Email sent with password reset instructions"
redirect_to root_url
else
flash.now[:error] = "Email address not found"
render 'new'
end
end
用户.rb
def send_password_reset_email
PasswordResetJob.new(self.email).enqueue(wait: 10.seconds)
end
app/jobs/password_reset_job.rb
class PasswordResetJob < ActiveJob::Base
queue_as :email
def perform(email)
UserMailer.password_reset(email).deliver_now
end
end
app/mailers/user_mailer.rb
class UserMailer < ActionMailer::Base
default from: "noreply@example.com"
def password_reset(user)
@user = user
mail to: user.email, subject: "Password Reset"
end
end
不知何故,来自user.rb的"self.email"没有传递给password_reset_job.rb。因此,错误"未定义的方法'电子邮件'为"bob@example.com":字符串"。
提前谢谢。
更新
根据普拉卡什的建议,再做一个如下的修改,把"self.email"改成了"自己":
def send_password_reset_email
PasswordResetJob.new(self).enqueue(wait: 10.seconds)
end
弹出一个新错误。这是错误:
ActionView::Template::Error
No route matches {:action=>"edit", :controller=>"password_resets", :email=>"bob@example.com", :format=>nil, :id=>nil} missing required keys: [:id]
以下是可能会有所帮助的更多详细信息。

<h1>Password reset</h1>
<p>To reset your password click the link below:</p>
<%= link_to "Reset password", edit_password_reset_url(@user.reset_token,
email: @user.email) %>
<p>This link will expire in two hours.</p>
<p>
If you did not request your password to be reset, please ignore this email and
your password will stay as it is.
</p>
您正在将电子邮件传递给 PasswordResetJob,后者将其传递给邮件程序,但邮件程序需要一个用户实例。
PS:可以直接在模型中做UserMailer.password_reset(self.email).deliver_later。请参阅 http://api.rubyonrails.org/classes/ActionMailer/MessageDelivery.html#method-i-deliver_later
def perform(email)
UserMailer.password_reset(email).deliver_now
end
这是在与email
UserMailer
调用 password_reset
方法(在此特定情况下其值为 bob@example.com
。
def password_reset(user)
@user = user
mail to: user.email, subject: "Password Reset"
end
所以在password_reset
方法中,user
被设置为 bob@example.com
,因此在调用user.email
时失败。
解决此问题的一种方法是使方法如下所示:
app/mailers/user_mailer.rb
class UserMailer < ActionMailer::Base
default from: "noreply@example.com"
def password_reset(email)
mail to: email, subject: "Password Reset"
end
end
您可能需要根据特定需求找到不同的方法。
