I'm still new to rails and simple_form and have been trying to implement a multiple select option to give a user multiple roles.
Current input looks like this
<%= f.input :secondary_role, :collection => UseridRole::VALUES, :include_blank => false,:label => "Secondary Role(s):", :input_html => { :class => " simple_form_bgcolour simple_form_position overide_selection_field_width", :size => 4, multiple: true } %>
So, this does work, but is including an empty value at the start of my array:
"secondary_role" : [
"",
"admin"
]
I have the same code above which works for my primary_role value which is a string, but my secondary_role can have multiple values so is stored as an array.
Where should I be looking to fix this issue?
It seems like Rails is adding a hidden field to the collection. Try adding include_hidden: false to your form input.
