Rails text_area size

Question

I have a text_area inside a fields_for, which is inside a form_for.

<%= day_form.text_area :hatch %>

Answer 1

As text area has both row and column you have to specify both

<%= text_area(:application, :notes, cols: 40, rows: 15, class: 'myclass') %>

For text field can use

<%= text_field(:application, :name, size: 20) %>
