I try to implement autocomplete on my place table that look like below:
{{{
class Place(models.Model):
name = models.CharField(max_length=80, blank=True)
num = models.IntegerField(null=True)
street = models.CharField(max_length=100, blank=True)
postal_code = models.IntegerField(null=True)
district = models.CharField(max_length=30, blank=True)
city=models.CharField(max_length=30, blank=True)
country = models.CharField(max_length=30, blank=True)
domicile = models.BooleanField(default=False)
def __str__(self):
address = "{0}, {1}, {2}, {3}".format(self.num, self.street,
self.postal_code, self.city,
self.country)
return address
}}}
and in my function that return the result for display my address on
frontend is like (self.q is a GET param from ajax call):
{{{
qs = Place.objects.all()
qs.annotate(search=SearchVector('street', 'country','city',
'num')).filter(search__icontains=self.q)
}}}
I have this error when the ajax call run:
{{{
File "/opt/coupdepouce/lib/python3.6/site-
packages/django/db/backends/utils.py", line 64, in execute
return self.cursor.execute(sql, params)
django.db.utils.DataError: invalid input syntax for integer: ""

Comment:
The problem seems to be
[https://github.com/django/django/blob/ba83378a7762c51be235b521aa5b48233d6c6c82/django/contrib/postgres/search.py#L56the
hardcoded] `Value('')`, regardless of the field type. I'm not sure what
the proper resolution is.
