ActiveRecord Find By Year, Day or Month on a Date field

Question

I have an ActiveRecord model that has a date attribute. Is it possible to utilize that date attribute to find by Year, Day and Month:

Model.find_by_year(201         


        

Answer 1

No need for extract method, this works like a charm in postgresql:

text_value = "1997" # or text_value = '1997-05-19' or '1997-05' or '05', etc
sql_string = "TO_CHAR(date_of_birth::timestamp, 'YYYY-MM-DD') ILIKE '%#{text_value.strip}%'"
YourModel.where(sql_string)
