Default value for input with simple_form

Question

im trying to do default value for input

works ok:

<%= f.input_field :quantity, default: \'1\' %> 

but i need f.i

Answer 1

This is an old question...but, none of provided answers seem acceptable to me. The best way to do this is to set the value in the controllers new action.

 def new
   WizBang.new(quantity: 1)

This will assign the objects quantity key to value 1 in the new action. The edit action should rely on the object's persisted value, or a params value if validation failed and the form reloaded. The other answers will force the quantity to 1 on edit, even if the user initially saved nil (if you allow nil). Not ok. I would not allow nil, but would include a 0 option in the quantity field.

f.input :quantity, collection (0..100)

much cleaner.
