Hi Guys,
I have the following code which grabs some data from the database in my
model
def get_stats
sql = “select id, value from table”
my_data = self.class.connection.select_all(sql)
my_data.group_by { |row| row[:id] }
end
the data is clearly in there as a puts shows
value4id1
value1id2
but when trying to access the values
x = my_data[1][:value]
The error occurred while evaluating nil.[]
Can anyone shed some light on this?
Cheers
