So building on @zzzeek's comments on @bukzor's code I came up with this to easily get a "pretty-printable" query:
def prettyprintable(statement, dialect=None, reindent=True):
"""Generate an SQL expression string with bound parameters rendered inline
for the given SQLAlchemy statement. The function can also receive a
`sqlalchemy.orm.Query` object instead of statement.
can
WARNING: Should only be used for debugging. Inlining parameters is not
safe when handling user created data.
"""
import sqlparse
import sqlalchemy.orm
if isinstance(statement, sqlalchemy.orm.Query):
if dialect is None:
dialect = statement.session.get_bind().dialect
statement = statement.statement
compiled = statement.compile(dialect=dialect,
compile_kwargs={'literal_binds': True})
return sqlparse.format(str(compiled), reindent=reindent)
I personally have a hard time reading code which is not indented so I've used sqlparse
to reindent the SQL. It can be installed with pip install sqlparse
.
