Make relational setup easier (O2M & M2O) Somehow the platform now requires the O2M and M2O to be defined separately. Not sure why because I didn't take a look at how it is saved in the database. In any case, once the M2O is defined, the O2M should be automatically there too. Or if it's not by design, they make it much easier to setup the O2M, like "Click here to generate the relation with table XXXX". Because all the info is already there. This is somehow related to feature http://feathub.com/directus/directus/+56 And I believe also related to https://github.com/directus/directus/issues/1102 For reference take a look at how the relationships work in strapi cms.
