Django ajax error response best practice

Question

I\'m using ajax to improve user experience in my Django project. My concern here is how to respond error to browser properly. As far as I know, I can either:

1. valid

Answer 1

I can't answer whether both methods are acceptable but can only tell you what I do. In my view I catch some specific/explicit errors such as:

• Invalid or missing params in post
• High level errors such as username already present in database (in a signup situation for e.g.)
• All other system errors

I think if you categorize your errors as some specific errors that the user must know about and then everything else then your code will have at the most 2 or 3 return with error routes, which IMHO isn't so bad. I use JSON to return errors and my structure is usually such:

respons={}
response["error|ok"]
response["msg"]="User not found"
response["type"]=ERROR_TYPE # only applicable for errors

Obviously this is quite basic but hopefully gives you a general idea. I would recommend against letting the user see the system generated internal server error. That is horrible user experience, even for internal apps.

Hope this helps.
