Django 1.11 - how to print SQL statements with substituted variables - sql

Question

This question is different than log all sql queries
I tried logging configurations from the answers above they are not working as I would like them to work, so please read on.
What I want to do, is to make Django (1.11.x) debug server log SQL queries in such a way, that I can redirect them to *.sql file and immediately execute.
For this I need a SQL statements where all the variables are already substituted, so I DON'T want this:
WHERE some_column in (:arg1, :arg2, ...)
but I want this instead:
WHERE some_column in ('actual_value_1', 'actual_value2', ...)
Can you please help me figure out how to do this?
Please note, that I don't want the SQL query to be printed in the browser (in some debug app like django_debug_toolbar) but printed to the console.
Please note, that I don't want to type Django QuerySet queries in console - I want to type URL in browser, so make an actual HTTP request to Django debug server and see it printing a SQL query in such a way I can execute it later using SQL Plus or any other console tools.

Answer 1

I think the tool I just made would be perfect for you.
https://pypi.python.org/pypi/django-print-sql
https://github.com/rabbit-aaron/django-print-sql
Install like this:
pip install --upgrade django-print-sql
Use like this in your view function:
from django_print_sql import print_sql
Class MyView(View):
def get(self, request):
with print_sql():
User.objects.get(id=request.user.id)
# and more....

This is a bit of a hack, because we have to strip the default django.db.backends log messages of the time taken and the args. After making these changes you should have a file of pure SQL that you are free to run as you wish...
First you want to set up your logging settings to reference our new log handler
Settings:
LOGGING = {
'version': 1,
'handlers': {
'sql': {
'level': 'DEBUG',
'class': 'my_project.loggers.DjangoSQLFileHandler',
'filename': '/path/to/sql.log'
},
},
'loggers': {
'django.db.backends': {
'handlers': ['sql'],
'level': 'DEBUG'
}
}
}
Then you need to define your new handler and strip out the unwanted text from the message.
my_project.loggers.py:
from logging import FileHandler
class DjangoSQLFileHandler(FileHandler):
def getMessage(self):
msg = super(DjangoSQLFileHandler, self).getMessage()
return record.msg.split(') ', 1)[1].split(';', 1)[0] + ';'
