There is an `collection_select` form builder that will do the `collect` for
you. So:
<%= f.collection_select :user, policy_scope(User), :id, :name %>
If you are not using a form builder then
`options_from_collection_for_select` is useful for the same purpose.
If those helpers cannot be used directly for some reason I create a custom
helper.
For example if I wanted to include the user's security role as a data
attribute for some sort of UJS behavior I might have:
def user_options selected
policy_scope(User).collect do |user|
content_tag 'option', user.name,
value: user.id,
selected: user.id == selected,
data: { role: user.role }
end.join.html_safe
end
Then in the view I might have:
<%= form.select :user_id, user_options form.object.user_id %>
