dsnparse
Parse dsn connection url strings. Responsible for parsing dsn strings in projects like prom and morp.
This is a generic version of dj-database-url.
So, now you can create dsns like this:
scheme://user:pass@host:port/path?query=query_val#fragment
For example, let's look at a prom dsn:
prom.interface.postgres.Interface://testuser:testpw@localhost/testdb
Now let's parse it:
import dsnparse
dsn = "prom.interface.postgres.Interface://testuser:testpw@localhost:1234/testdb"
r = dsnparse.parse(dsn)
print(r.scheme) # prom.interface.postgres.Interface
print(r.username) # testuser
print(r.password) # testpw
print(r.host) # localhost
print(r.port) # 1234
print(r.hostloc) # localhost:1234
print(r.paths) # ['testdb']
Also, dsnparse can easily use environment variables:
r = dsnparse.parse_environ('ENVIRONMENT_VARIABLE_NAME')
I tried to keep the interface very similar to urlparse so it will feel familiar to use.
Customizing
By default, dsnparse.parse(dsn) returns a ParseResult instance, but that can be customized:
import dsnparse
class MyResult(dsnparse.ParseResult):
def configure(self):
# expose an interface property
self.interface = self.scheme
dsn = "Interface://testuser:testpw@localhost:1234/testdb"
r = dsnparse.parse(dsn, parse_class=MyResult)
print(isinstance(r, MyResult)) # True
print(r.interface) # Interface
