This is completely wrong. This usually looks something like
params.require(:invitation).permit(:attended_event_id, :attendee_id)
which says that the params hash should contain an element for the key :invitation, and that the two named parameters are allowed to be present. (A more elaborate syntax allows for array and hash values - lookup the docs for 'strong parameters')
My view showing the list of users and after selecting a checkbox, should pass the event_selected and user_ids.
invitations/new.html.erb
<h3>Invite users to <%= @event_selected.name %></h3> <%= bootstrap_form_for Invitation.new do |f| %> <br> <ul> <% @users.each do |user| %> <li> <%= hidden_field_tag :event_selected, @event_selected.id %> <%= check_box_tag 'user_ids[]', user.id %> <%= h user.name %>
When you use the _tag helpers (as opposed to g.hidden_field, f.check_box), then your parameters aren't nested with invitation hash as mentioned above. You'll also make your life much easier if the input names correspond to the model attribute names (i.e. attended_event_id instead of event_selected). It also seems a bit odd (although probably harmless) that you are repeating the event_selected input.
