Now sure how a duplicate Question's answers get referenced, but I am sharing an Answer I just left on a question I flagged as a duplicate.

Here is a summary for this question:

 # simple_form input
 f.input :quantity, input_html: {value: f.object.quantity || '1'}

can become:

 # simple_form input
 = f.input :quantity, input_html: { value: f.object.quantity_with_default }

 # Model with date_start attribute
 class Obj
   def quantity_with_default
     # based on your model, you may need this instead: try(:quantity) || '1' 
     quantity || '1' 
   end
 end

This leaves the management of the data and its defaults in the controller instead of sprinkled throughout the HTML
