Question

I am using simple_form and have a following sample tag:

<%= f.input :medical_conditions, :label=>false, :collection => medical_conditons, :as => :check_boxes%>

The collection holds about 100 checkboxes. However, when user only selects 1 or 2, everything is still getting saved to the database like this:

---
- ""
- ""
- ""

medical_conditions is a simple array in my application_helper

def medical_conditons
t = [
    "Allergies/Hay Fever",
    "Diabetes",
    "Heart Surgery"]
return t
end

the medical_conditions field is a :string field.

What do I need to do so that only values that are selected are saved in comma separated manner.

Answer 1

It is not simple_form behavior. It is from Rails. See this: http://d.pr/6O2S
