[Answered ]-Django: Access model field with two keys in template

You need to reverse query the scores. Since you’ve defined related names in your models, you can use them.

Note that a reverse query gives you a manager object. The all method returns a queryset with all objects matching the reverse query (you defined a one-to-many relationship, one question/vendor can have many scores). Then further filter the queryset to get the instance you need (e.g. first).

{{vendor.scorevendor.all.first.score}}
