ruby on rails - Where should background job logic go -

-

I am using rail and rushes but it is more of a design question, where real logic with background jobs should go.

I have a class like this: 

  class ticket # 1) should the method go here? End   
 and a BG job like this:  
  Module jobs class Patient # 2) Or should the method go here? End End   
 Then there is a method that operates the billing for the ticket. It makes two network calls (one of which will be slow), so it is clear that we need a background job  
  def pay_ticket # call stages and other network call end   should go.  
 Whether there are some common ideas on fats background jobs on people or if this argument usually remains in the model. Or if it depends on each situation thanks!   
 
 
 It really depends on how you want to cover your code. I'm a strong believer Intel  fat  is a model design pattern, but it is actually dependent on each developer in any way it seems like circumstances will be cured, so I think my first question is, do you share project Are developing in (i.e. other people will work on this code ?)  
 If not, then I say in the 'model' through it and possibly keep the logic associated with the nearby model of the source.  
 If you are, then it may be a little dangerous to expose the argument, but a comment is in fact it is not a big deal.  
 If you do not want  actually  to call that method, but you want to follow the OOP / encapsulated approach, you always sub-class the ticket model. You have all the functionality but do not expose the  payment  method, for example:  
  #model / ticket.rb class ticket ... end #lib / PBLTicket. Rb class payable ticket and lieutenant; Ticket deaf payment .... and end   
 Just my two cents, but I hope that helps.

python - Receiving "KeyError" after decoding json result from url -

-
I am new to Python I am trying to parse JSON result from a URL. Basically, I was using the following: response = urllib.request.urlopen (url) json_obj = json.load (response) It should be a stroke "str 'not' bytes' in the lines of a given" JSON object, so after searching on the StackoverView Flo, I decode the response in this way: F = urllib.request.urlopen (Url) charset = f.info (). Get_param ('charset', 'utf8') data = f.read () decoded = json.loads (data.decode (charset)) If I print "decode" I is as follows: { 'link': { 'summary data': 'https: // localhost / piwebapi / streams / p0_7qHaW4UHU-RlCaz8tpasAAQAAAAU0hJTExNQU42NDIwXFNJTlVTT0lE / summary' 'value': 'https: // localhost / Piwebapi / streams / P0_7qHaW4UHU-RlCaz8tpasAAQAAAAU0hJTExNQU42NDIwXFNJTlVTT0lE / price ',' InterpolatedData ':' https: // localhost / Piwebapi / streams / P0_7qHaW4UHU-RlCaz8tpasAAQAAAAU0hJTE...

.net - Creating a new Queue Manager and Queue in Websphere MQ (using C#) -

-
"itemprop =" text "> I am writing applications that use WebSphere MQ to send messages. My unittests (for flow), I want to verify that I have put the correct message on the response queue. I am trying to figure out how to do this. My main obstacle is that I think it might be scary to clear the queue before running in my queue because the same queue can be used by other applications, I thought a decent solution would be a new line The manager will remove the queue for my solidarity and after using it. So my question is: Is it possible to use C # by using queue manager and queue? After the For future reference and future people, who want to make queues. I thought how to make and remove IBM MQ QE (not quenhers) with PCM messaging. It is not very simple, but it can be done. We have implemented it in a library and it is being used to create and delete commands before and after integration tests. The most important part of the code in this library is shown in the...
