how grouping day instead of date? 4 answers

im creating time line columns table. @ moment time line display each column ordered "created_at" field. want piece each day this:

today content -| | |- content | content -| | yesterday | |- content | content -|

at moment using code

<ul> <% @timeline.each |timeline| %> <li> <%= timeline.title %> </li> <% end %> </ul>

i want "each_slice(5)" function. hope can tell me how this. in advance.

you can grouping array ruby group_by:

@timeline.group_by { |el| el.created_at.to_date.to_s(:db) }

note: assume @timeline sorted.

probably, method reusable, improve place in models like:

def self.to_grouped_by_day group_by { |el| el.created_at.to_date.to_s(:db) } end

and phone call in controller.
