You could use Enumerable::group_by to collect-up your records by date,
and see if the resultant collection includes the date in question (and
if not, add it if you need to)
all_results = Item.where(--- created in my date range ---)
grouped_all_results = all_results.group_by{|result|
result.created_at.strftime("%Y%d%m")}
if grouped_all_results.include?(current_time.strftime("%Y%d%m"))
... do something
else
do something else
end
You might make your group_by date and your lookup date by some other
method (like "date_value.to_s" or something), but as long as they end
up in the right format, it should work...
