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|
policy_scope(User).collect do |user|
content_tag 'option', user.name,
value: user.id,
selected: user.id == selected,
data: { role: user.role }
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 %>
<%= form.select :user_id, user_options form.object.user_id %>
Good Morning Everyone...I have a coding question just so I am clear on the proper way to do this...To start, I have an app that I use Pundit in to control access to data, so I have a lot of calls that are like policy_scope(User)What is the proper way to populate a select on a form with this data?Initially I was just using policy_scope(User).collectHowever I don't think it is proper to use this in a view, is it?If not, what is the proper way to pull this data and provide it to the form?Recently I have moved some of these to helpers and created a method like "users_for_select"John
