I have problem in django using query statement "LIKE %s%" with
Model.objects.raw(). I guess the problem is on '%' character but i don't
know where is it. Here's my model's code:
def listInRange(self, placeLat, placeLng, typeId, range, placeTag):
tags = ''
if placeTag:
tags = " AND (placeTag LIKE '%" + "%' OR placeTag LIKE
'%".join(placeTag.split(',')) + "%')"
query = "SELECT *, \
( \
6371000 * \
acos( \
cos( radians(%s) ) * \
cos( radians(placeLat) ) * \
cos( radians(placeLng) - radians(%s) ) + \
sin( radians(%s) ) * \
sin( radians(placeLat) ) \
) \
) AS placeDistance, \
COUNT(r.reviewId) as placeReviews, \
(SUM(r.reviewPointPrice)/COUNT(r.reviewId)+SUM(r.reviewPointService)/COUNT(r.reviewId)+SUM(r.reviewPointLocation)/COUNT(r.reviewId)+SUM(r.reviewPointCondition)/COUNT(r.reviewId)+SUM(r.reviewPointComfort)/COUNT(r.reviewId))/5
AS averagePoint \
FROM place_place p \
LEFT JOIN review_review r \
ON r.reviewPlace_id = p.placeId\
WHERE placeType_id = %s %s \
GROUP BY p.placeId \
HAVING placeDistance < %s \
ORDER BY placeDistance"
return Place.objects.raw(query, [placeLat, placeLng, placeLat,
typeId, tags, range])
If placeTag is not empty, then it will added to the WHERE condition. When
the placeTag is empty there's no such problem, but when placeTag is not
empty i got this error :
Warning: Truncated incorrect DOUBLE value: '1 AND (placeTag LIKE
'%cafe%' OR placeTag LIKE '%pub%')'
I think python make '1 AND (placeTag LIKE '%cafe%' OR placeTag LIKE '%pub%')'
as the value for placeType_id. How can i make the value of placeType_id=1
and add the AND statement? What's the better way to write the sql statement
using Model.objects.raw() with 'like' statement?
