[英]Rails 4 model.where returning JSON instead of hash
I have a list of contacts
in my database. 我的数据库中有一个
contacts
列表。 I am calling them like so: 我这样称呼他们:
contacts = Contact.where(loaded_at: nil, failed_at: nil)
contacts[0]
returns the following: contacts[0]
返回以下内容:
=> #<Contact id: 96, client_id: 2027, branch_id: 100, phone_type: "Mobile", unit_type: "Family", phone_number: "(123)456-7890", text_message_id: nil, loaded_at: nil, created_at: "2014-03-17 22:01:53", updated_at: "2014-03-17 22:01:53", failed_at: nil>
I'm then trying to loop through all contacts
in my Sidekiq worker: 然后,我试图遍历我的Sidekiq工作者中的所有
contacts
:
def perform()
contacts = Contact.where(loaded_at: nil, failed_at: nil)
contacts.each { |contact| TextSendWorker.perform_async(contact) }
end
This throws the following error: 这将引发以下错误:
WARN: {"retry"=>true, "queue"=>"default", "class"=>"ContactWorker", "args"=>[], "jid"=>"3d3373e14f4bfe9ae2aa2cae", "enqueued_at"=>1395093915.4475722, "error_message"=>"undefined method `key?' for #<JSON::Ext::Generator::State:0x007f40b0bd42d0>", "error_class"=>"NoMethodError", "failed_at"=>1395093915.4909346, "retry_count"=>7, "retried_at"=>1395096684.1267653}
WARN: undefined method `key?' for #<JSON::Ext::Generator::State:0x007f40b0bd42d0>
So, it looks like my contacts
array is actually returning an array of JSON
objects instead of a hash. 因此,看来我的
contacts
数组实际上返回的是JSON
对象数组,而不是哈希值。 I don't think I've ever seen this, it seems that I always receive a hash when calling Model.where()
. 我认为我从未见过,似乎在调用
Model.where()
时总是收到哈希值。
What is causing this, and how can I loop through contacts
within my worker like I need to? 是什么原因造成的,以及如何像我需要的那样循环遍历我的工作人员中的
contacts
?
Full class below: 完整课程如下:
class ContactWorker
include Sidekiq::Worker
def perform()
contacts = Contact.where(loaded_at: nil, failed_at: nil)
contacts.each { |contact| TextSendWorker.perform_async(contact) }
end
end
Sidekiq serialize passed params to store they as redis, and I thing that problem of you serializer. Sidekiq对传递的参数进行序列化以将它们存储为Redis,而我觉得序列化器存在问题。
I recommend you follow this document a Best Practices and rewrite code: 我建议您按照本文档的“最佳实践”并重写代码:
class ContactWorker
include Sidekiq::Worker
def perform()
contacts = Contact.where(loaded_at: nil, failed_at: nil)
contacts.each { |contact| TextSendWorker.perform_async(contact.id) }
end
end
