Hi Anthony, thanks for the answer,
Your solution is pretty nice but I am still calling it 3 times which
actually is the main problem since I am asking 'google' 3 times the same
stuff.
Is it possible to store the answer somewhere (cache?) the first time
and then use the cache copy for the latter calls?
Regards,
Paolo

To get it down to it down to one function, how about:
def compute_geoCode(r, component):
g = geocoders.Google()
place, (lat, lng) = g.geocode(r.name [4])
return eval(component)
db.cities.full_address.compute = lambda r: compute_geoCode(r,
'place')
db.cities.lat.compute = lambda r: compute_geoCode(r, 'lat')
db.cities.lgt.compute = lambda r: compute_geoCode(r, 'lng')

Hi all,
I have a simple table with 3 computed fields, the function that set
their values is almost the same. However, unfortunately I had to set
up
three different functions because I didn't find a better approach.
The code:
db.define_table('cities',
Field('name', 'string', requires=IS_TRIM()),
Field('full_address', 'string',requires=IS_TRIM()),
Field("lat", "double", label=T('Latitude')),
Field("lgt", "double", label=T('Longitude')))
db.cities.full_address.compute = compute_geoCode_place
db.cities.lat.compute = compute_geoCode_lat
db.cities.lgt.compute = compute_geoCode_lng
def compute_geoCode_place(r):
g = geocoders.Google()
place, (lat, lng) = g.geocode(r.name [1])
return place
def compute_geoCode_lat(r):
g = geocoders.Google()
place, (lat, lng) = g.geocode(r.name [2])
return lat
def compute_geoCode_lng(r):
g = geocoders.Google()
place, (lat, lng) = g.geocode(r.name [3])
return lng
What I would like to find is a way to fire the execution of a
function
when the form is submitted. More or less something like a compute
action
at table level.
