ODOO每一个website都可以绑定一个域名，不同的域名对应不同的网站，本质上是因为ODOO根据访问的域名不同去匹配不同的网站，然后再根据路由去取得不同的页面，代码如下
@api.model
def get_current_website(self, fallback=True):
""" The current website is returned in the following order:
- the website forced in session `force_website_id`
- the website set in context
- (if frontend or fallback) the website matching the request's "domain"
- arbitrary the first website found in the database if `fallback` is set
to `True`
- empty browse record
"""
is_frontend_request = request and getattr(request, 'is_frontend', False)
if request and request.session.get('force_website_id'):
website_id = self.browse(request.session['force_website_id']).exists()
if not website_id:
# Don't crash is session website got deleted
request.session.pop('force_website_id')
else:
return website_id
website_id = self.env.context.get('website_id')
if website_id:
return self.browse(website_id)
if not is_frontend_request and not fallback:
# It's important than backend requests with no fallback requested
# don't go through
return self.browse(False)
# Reaching this point means that:
# - We didn't find a website in the session or in the context.
# - And we are either:
# - in a frontend context
# - in a backend context (or early in the dispatch stack) and a
# fallback website is requested.
# We will now try to find a website matching the request host/domain (if
# there is one on request) or return a random one.
# The format of `httprequest.host` is `domain:port`
domain_name = (
request and request.httprequest.host
or hasattr(threading.current_thread(), 'url') and threading.current_thread().url
or '')
website_id = self.sudo()._get_current_website_id(domain_name, fallback=fallback)
return self.browse(website_id)
如果是没有指定website_id， 那么便根据下面代码进行搜索
domain_name = (
request and request.httprequest.host
or hasattr(threading.current_thread(), 'url') and threading.current_thread().url
or '')
最终找到要访问的website
website_id = self.sudo()._get_current_website_id(domain_name, fallback=fallback)
