Hi all,

we find a solution for use %h and subdomain, create your db in replace '.' by '-'.

Example : for the domaine erp.pharmacy.com, create db erp-pharmacy-com

And in your file .conf, at line dbfilter, write this : dbfilter = %h

Works for Odoo v8

I had a similar problem. It is not possible with Odoo to filter db's on anything other than the subdomain or, if the subdomain is 'www', the domain. I wanted to map company domains to different dbs, like this:

http://accounts.company1.com => db = company1

http://accounts.company2.com => db = company2

To fix this, I had to modify the function db_filter in http.py:

if d == "www" and r:

becomes:

if (d == "www" or d == "accounts") and r:

You can have different prefixes you want.

Houssine,

I tried using your suggestion of --db-filter=^%h$, but it did not work. From my understanding %h would be "sub.domain.com". I tried creating a database that was  called "domain" and it did not work, so I tried creating "sub.domain.com", but it said that was invalid, so I tried "subdomaincom" and that still did not work, any ideas? (Odoo V8)

UPDATE: I believe this is not possible using only Odoo, I believe you have to use a 3rd party application like Apache or NGINX.

I found this guide for Reverse SSL Proxy with NGINX: http://www.schenkels.nl/2013/01/reverse-ssl-proxy-using-nginx-with-openerp-v7/

Anyone have any documentation relating directly to routing domains? Thanks!

You should select --db-filter=^%h$
