In your python code, add this "import pdb; pdb.set_trace()' at the place you want the breakpoint. Then run: python manage.py runserver Then go to your web page that will cause your code to be invoked, but add :8000 to the address (e.g. http://127.0.0.1:8000/...) Then when it hits your breakpoint you can set other breakpoints, print out variables, step though your program, etc. http://docs.python.org/2/library/pdb.html > On Wednesday, July 17, 2013 10:17:10 PM UTC+7, [email protected] wrote: >> >> On Wed, Jul 17, 2013 at 9:15 AM, spondbob squelpen <[email protected]> >> wrote: >> > the '1' is coming from typeId, so the WHERE condition must be look like: >> > WHERE placeType_id=1 AND (placeTag LIKE '%test%') >> > >> > print out tags: >> > AND (placeTag LIKE '%test%') >> > >> > i have tried your solution by adding double percentage but still got >> > same >> > error >> >> Like I said, use the debugger. >> >> > >> > On Wednesday, July 17, 2013 10:04:48 PM UTC+7, [email protected] >> > wrote: >> >> >> >> On Wed, Jul 17, 2013 at 8:58 AM, spondbob squelpen <[email protected]> >> >> wrote: >> >> > where do i put those double percentage? like this? >> >> > tags = " AND (placeTag LIKE '%%" + "%%' OR placeTag LIKE >> >> > '%%".join(placeTag.split(',')) + "%%')" >> >> > >> >> > but still got the same error: >> >> > Warning: Truncated incorrect DOUBLE value: '1 AND (placeTag LIKE >> >> > '%%test%%')' >> >> >> >> Where is the '1' coming from?
