How to shard the Django User model/table? -

-

How can you push the Django user model so that the user records different databases / tables?

Which modules and models and ideas need to be modified? Do I need to create a custom authentication backend? Is there a relatively painless way to do this?

Thank you.

It is difficult to design because it is designed in a proper malicious way.

I believe that you are concerned with the number of institutions kept in a database? Otherwise, if scaling thinking, normal load balancers - web server - connection pooling - use database cluster setup.

qt - switch/case statement in C++ with a QString type -

-
I want to use switch-case in my program but the compiler generates an error. How can I use the switch statement with QString ? The compiler gives me this error: The expression of the switch type 'QString' is invalid My code is as follows : boolStopWord (the word QString) {bool flag = false; Switch (word) {case "the": flag = true; break ; "On" case: flag = true; break ; Case "in": flag = true; break ; Case "your": flag = true; break ; Case "near": flag = true; break ; Case "all": flag = true; break ; Case "this": flag = true; break ; } Return flag; } How do I use the switch statement with a Caststring ? You can not use the switch statement in C ++ language with integral or enum types. You can formally enter the square type of object in the switch statement, but this means that the compiler will look for a user-defined conversion to convert it to an integral or enum type.
