Hello, I allow user to chat in channel but disable them in direct message. In this case, a non-staff user can still see Chat button in others’ user card. But they may get wrong message after click it.
I read the code, the button is shown if can_chat_user
. This is determined by following code.
# plugins/chat/plugin.rb
add_to_serializer(:user_card, :can_chat_user) do
return false if !SiteSetting.chat_enabled
return false if scope.user.blank?
scope.user.id != object.id && scope.can_chat?(scope.user) && scope.can_chat?(object)
end
and
# plugins/chat/lib/guardian_extentions.rb
def can_chat?(user)
return false unless user
user.staff? || user.in_any_groups?(Chat.allowed_group_ids)
end
