Here's one way to do it. Note that when I start having this kind of
problems I usually stop using the grid and make a custom solution.
In the grid, the searchable argument, can be a function. In that case it
gets the fields and keywords and its responsibility is to generate and
return a query. You can disable advanced_search and then only have a search
field. Then you will have a searchable function which will detect if one of
the keywords entered in the search is a date, if that is the case then you
will make a query where only records from that date are acceptable.
Your controller function would be something like this:
def mygrid():
import datetime
def searchable(fields, keywords):
query = db.my_table.id > 0:
for keyword in keywords:
date = None
try:
date = datetime.datetime.strptime(keyword,'%Y-%m-%d')
except ValueError:
pass
if date:
query &= db.my_table.created_on == date
else:
# this is just an example
query &= db.my_table.name.like('%' + keyword + '%',
case_sensitive=False)
return query
return {'grid': SQLFORM.grid(db.my_table, searchable=searchable,
advanced_search=False)}
