Reusing code across multiple sites

Hi all,

I have a setup where I will have having around 50 sites using the same 
code, configured slightly differently. Rather than deploy the same code 
over and over again, duplicated across different folders and repositories,
is there any way to centralise the working code of the site, as some sort 
of library?

In Django I was able to find this: 
https://docs.djangoproject.com/en/dev/ref/contrib/sites/ but I can't seem 
to find or come up with a similar solution in flask.

Any help or advice would be much appreciated.

James

I would immediately go to making your own "extension"
http://flask.pocoo.org/docs/extensiondev/

This should be perfectly valid for what you'd like to do, no?

Hi James,

I very recently ran into a similar problem, and application dispatching did
exactly what I needed.

http://flask.pocoo.org/docs/patterns/appdispatch/

I was able to dispatch requests to separate apps. For me, it was based on
hostname - client1.domain.com got one instance of the app with a different
config, client2.domain.com got a different app, with their specific config.

The things I had to watch out for was doing anything on import (like doing
some sort of setup in __init__.py when a module was imported), or storing
anything on the class instead of an instance of the class.

Anyway, this worked/is working great for me - I was afraid I'd have to run
a different gunicorn per client, but this saved the day.

So build the logic to get the configuration for the hostname directly in
the main application and load a specialized configurations in a
@before_request handler?
