I would like to have a database of fashion models on my blog.
The models section will be located under /models/. There shall be a loop of recent posts with models as well as the full list of models names.
Singe page of a model shall have URL: /models/kate-moss.
Each model’s single page should be a custom wordpress post, including basic description, photos and special fields like age and birth date, weight and height etc.
On the single page template below the description of the model there shall be a list of posts related to the person.
One more important thing: when an author publishes a post they should be able to simply choose the related person from the list with a checkbox.
In other words the person is neither custom taxonomy nor custom post, it is both. But how to implement it?
Have a taxonomy, with terms that are the same as the custom post type. Then in your taxonomy template, grab the custom post type that has the same post name as the current term slug.
You can automate this slightly by having the celebrity term automatically created when you add the celebrity post etc
Refer to this answer for how to do that:
How to add automatically keyword to taxonomies when a post published, and assign them to the post
Judging from this, what you originally asked is not what you want at all, so any answer trying to answer it will not be accepted. Ideally I should flag this and attempt to close it, or edit your question based on what you revealed in your comment.
If you have a post type named
modelsthen add an archive-models.php in your theme and put your loop in there. That will be the archive for your models post type, aka your landing page.Have a look at the Posts 2 Posts plugin, which provides an interface for creating many-to-many connections between posts.
