I'm using Simple_form to list a POSTGRES array in a Rails4 app:
<%= f.input :categories, label: 'Categories:',
collection: @user.categories,
as: :check_boxes,
input_html: { style: 'width: 50px' } %>
...which produces a checkbox list in the form. Unchecking values removes them successfully.
The problem is, how do I get a text input from Simple_form to add/inject new values to the Model's categories attribute (which is of type POSTGRES array)?
