How to incorporate the body field back into a content type from which it has been previously deleted? I am on D7. In the past, I have deleted the body field from a certain content type in my project. Now, the problem is that I want the body field back into this same content type, but cannot find it in the list of existing fields in my project to be added to the content type. How can I add the deleted body field back into the content type? Is it possible? It is important to say that I don't want its content back. I just want the regular Body field with the original ID body, instead of creating a "field_body". Thanks.
In a hook_update_n(), module_install(), module_enable(), or devel module eval php code:

$types = node_type_get_types();
node_add_body_field($types['my_content_type_name']);


giving it the machine name of your content type, and optionally you may provide a label for what you want the human readable label for the field to be (defaults to 'Body'). see node_add_body_field() API documentation
