Question

I am sure this is a silly question, but I have been searching for some time now without finding an answer.

I have a nested form using simple_forms. I get all the child objects successfully with

 = f.simple_fields_for :fund_levels do |fl|
     = fl.input :title
     = fl.input :description
     = fl.input :maxnumber
     = fl.input :price

This gets all existing fund_levels. However, I also want to add a blank set at the end of the list. So that if there are no existing fund_levels, it simply shows a blank “subform”, if there are two existing fund_levels, it will show those two plus a blank “subform”.

Is there an easy way of doing this?

Answer 1

Build it in your controller:

@object.fund_levels.build

where @object is the object being passed to form_for.
