Save only the year in a date field on Postgres! RAILS

Question

I have two fields called start_year and end_year, in which I want to save only the year that the user will select and save in the database. But when you save the form that is processed by RAILS, it saves year, month and day.

I wonder if I can save a date type data in Postgres by storing only the year through RAILS.

On the web page and basically as soon as you get the data

That in html.erb the code is like this []

In the database there is a table that would be the one that is the creation of user by.

And in this photo below are the fields that are added to the user table, in which follows the fields start_year and end_year

Answer 1

In this case, you will have to change the field type in the database in your Migration.

of - (instead of using datetime)

create_table :nome_da_tabela do |t|
  t.datetime :inicio_ano
  t.datetime :termino_ano
end

To - (use an integer)

create_table :nome_da_tabela do |t|
  t.integer :inicio_ano
  t.integer :termino_ano
end

And in time to save you must extract the year. Example: Time.year returns 2018
