We need to link multiple posts to each other, in several new sites we have to build for clients. Our developer told us:
"Actually toolset doesn't allow to select parent when relationship is many to many
Like in this case we wanted to select one or more celebrities
They have it for 'one to many' and 'one to one'
But for 'many to many' its an issue"
For example, we need to connect one or more posts about towns, to news and classifieds about those towns. In another site, we need to connect celebrity bios, to news and reviews about the involved celebrities.
"Actually toolset doesn't allow to select parent when relationship is many to many"
This is false, if you want to connect the posts on the frontend in a many to many relationship you will need to make use of a relationship form. It is true that with a normal one to many or one to one, you can setup the relationships when the post is being created on the frontend.
The relationship form requires that the Post has already been created, and you will add the form to the template of the page that you want to connect to another post.
Problems that you will face here is that if you want to connect multiple parents at the same time you won't be able to as you can only do it one at a time from the frontend.
Ofcourse you do have the option to hide this form and allow it to only be visible to the users who should have access to see it. This can be done with our Access plugin by going to Toolset -> Access Control -> Toolset Forms.
If there is anything that you are not clear about please let me know and I will be more than happy to clarify.
