Question

I wonder how to do multifield sorting in mongodb driver of ruby

Example of sorting from official site where we can find the following example:

# Sort in ascending order by :i
coll.find.sort(:i)

# Sort in descending order by :i
coll.find.sort(:i => :desc)

According to these examples I tired to do something like this

coll.find.sort(:i,:j)

and this is didn’t work

Do you know the right way to do multifield sorting in ruby driver.

Answer 1

after a short investigation the answer was found

we can use either

hash_as_sort_parameters({:field1 => :asc, "field2" => :desc})

or

array_as_sort_parameters([["field1", :asc], ["field2", :desc]])

the first way with hash doesn’t work for me for some reason, but the second is completely ok
