collection_check_boxes with checked:

[tkhduracell]

I can't get the collection_check_boxes to work with checked: - attribute. If I use bootstrap_form_tag what do the checked: accept?

• checked: [1,2,3,4]
• checked: ["1","2","3","4"]
• checked: MyActiveModel.all

E.g.
<%= f.collection_check_boxes "[search][post_type][]", PostType.all, :id, :name, checked: ["1"], hide_label: true %>

I am facing the same problem. It seems to only take a single value...

Same problem :(

Yes, at this moment the method works with only a single value.

And accept multiple values makes total sense, I'll try to work on it this weekend.

<%= f.collection_check_boxes :disciplina_ids, Disciplina.all, :id, :nome, checked: JSON.parse(@professore.disciplina_ids) %>
In My Controller i store the values using
:disciplina_ids => []
This way i can store an array of values and retrieve then on edit
