Thanks Niphlod.
I worked for me.
Here is the complete code.
In my controller:
sum_of_entries = db.mydiary.id.count()
year_part = db.mydiary.Entry_Date.year()
distinct_years = db(db.mydiary.id 0).select(sum_of_entries, year_part,
groupby=db.mydiary.Entry_Date.year(), orderby=~sum_of_entries)
it's the same method as extrapolating the count() part
year_part = db.mydiary.Entry_Date.year()
distinct_years = .
for row in distinct_years:
only_year = row[year_part]

Entry_Date.year(), groupby=db.mydiary.Entry_Date.year(), orderby=~

In my view I'm trying to display the results in a loop like so:
Yes sir, I'm sure. The sample database I had sent previously and my production
database both have records in them.

are you sure that there are effectively records on the table ?

It might be helpful to use appadmin to examine a few records. Appadmin
can also be used to enter a few sample records. If Moiz still has
problems, perhaps
Hello,
Sorry to bug you all, but I am still stuck with this year groupby issue.
I am fairly new to Python and web2py.
Any suggestions or alternative method to achieve the result is highly
appreciated.
Thank you all.

trangely, this is what I get with the same app, same data, same code, both
on pythonanywhere and my local machine.

are you sure that the issue is not fetching but rather visualizing the
results you already fetched ???

Thanks Niphlod for the replies.
The code you provided does not seem to work for me.
I tried the attached app on my local machine with SQLITE as well as MySQL
on PythonAnywhere
This is the controller:
def year():
sum_of_entries = db.mydiary.id.count()
years = db(db.mydiary.id 0).select(sum_of_entries, db.mydiary.Date.
year(), groupby=db.mydiary.Date.year())
# years = db(db.mydiary.id 0).select(db.mydiary.Date.year(),
distinct=True)
return locals()
Both of the approaches you suggested are not yielding any results.
given that db.entries.date is a datetime field, the former is fetched with
db(db.entries.id 0).select(db.entries.date.year(), distinct=True)
while the latter, e.g. the entry count per year, with
sum_of_entries =
I assure you you will get results, as long as there are values in the
table
try using:
1) this model in a fresh app
db.define_table('entries', Field('this_is_datetime', 'datetime'))
2) fill some data in
3) create this controller function
def test():
distinct_ = db(db.entries.id
the doc is rather incomplete. Either you want a set of distinct things, or
you want to aggregate something over a group of distinct things.
given that db.entries.date is a datetime field, the former is fetched with
db(db.entries.id 0).select(db.entries.date.year(), distinct=True)
