Create belongTo relationship from gui?

[gpatri]

In admin panel we can create many-to-many one-to-many, how to connect entities one on one (belongTo). We need to connect 1 entiti to contact.

thanks

Hello
Now it is possible only with file modification. As example you can use relationship between contact (originalLead) and lead (createdContact)
in application/Espo/Modules/Crm/Resources/metadata/entityDefs/Contact.json and Lead.json
