Not getting accurate data on multiple field group

Rails
1

Hi,

I am executing this query:

=====
@monthly_data = ReviewRating.group(“date_format(insertdate, ‘%Y/%m’),
type”).count(:conditions => {:insertdate => ‘2011-01-01’…‘2099-01-01’})

(12.7ms) SELECT COUNT(*) AS count_all, date_format(insertdate,
‘%Y/%m’), type AS date_format_insertdate_y_m_type FROM
tc_reviews_rating WHERE (rev_user_id != 0) AND
(tc_reviews_rating.insertdate BETWEEN ‘2011-01-01’ AND ‘2099-01-01’)
GROUP BY date_format(insertdate, ‘%Y/%m’), type

=> {1=>477, 2=>26}

where as if I execute the SQL directly, I get the correct data.

What am I doing incorrect? Thanks in advance for the help.

When you use the string form of group, rails doesn’t look into the string
to see that you are grouping on 2 different things.
I’d try group(“date_format(insertdate, ‘%Y/%m’)”, “type”)
