Does anyone know the best way to display a list of rows grouped by month  
in a view?

An example would be:

December

Dec. 15, Saturday at 8:30pm: Some Field

Dec. 9, Sunday at 8:30pm: Some Field

Dec. 5, Wednesday at 8:30pm: Some Field

November

Nov. 15, Saturday at 8:30pm: Some Field

Thanks for any help.

group\_by() {|element| …}

Collect an enumerable into sets, grouped by the result of a block.  
Useful,  
for example, for grouping records by date.

e.g.

latest\_transcripts.group\_by(&:day).each do |day, transcripts|  
p “#{day} -\> #{transcripts.map(&:class) \* ', '}”  
end  
“2006-03-01 -\> Transcript”  
“2006-02-28 -\> Transcript”  
“2006-02-27 -\> Transcript, Transcript”  
“2006-02-26 -\> Transcript, Transcript”  
“2006-02-25 -\> Transcript”  
“2006-02-24 -\> Transcript, Transcript”  
“2006-02-23 -\> Transcript”
