Q:

How to get the database and table name from a ReQL query

Suppose I have the following RethinkDB query (as printed in iPython):
In [32]: data_to_archive
Out[32]: <RqlQuery instance: r.db('sensor_db').table('sensor_data').filter(lambda var_2: (r.row['timestamp'] < (r.now() - r.expr(259200.0)))) >

The query is on the database sensor_db and table sensor_data, as is clear from the printed output.  Is there any way I can retrieve this information as an attribute of the RqlQuery instance? 
(The reason I want to do this is to write succinct code: the query, the database, and the table are currently all passed separated as input arguments to a function, but the latter two are actually contained in the former). 

A:

Not sure if it exists.  Meanwhile, a little ugliness hasn't really hurt anyone except my mom:
In [57]: mom = lambda q, fn: re.search(fn + "\(\'(.*?)\'\)", str(q)).group(1)

In [58]: rql = r.db("foo").table('bar').filter(lambda x: x)

In [59]: mom(rql, 'db')
Out[59]: 'foo'

In [60]: mom(rql, 'table')
Out[60]: 'bar'
