How to Pass Predicates Stored in a Variable to expand() Function

[utekaravinash (Avinash Utekar)]

In DGraph documentation, it is mentioned that we can use expand() function in four ways. One of them is:

• Predicates can be stored in a variable and passed to expand() to expand all the predicates in the variable

Could someone please give an example as to how it can be achieved?

Sorry for the late answer, I missed that one.

Predicates can be stored in a variable and passed to expand() to expand all the predicates in the variable

This was deprecated since the _predicate_ feature was removed in favor of the new Type System. You can see the usage in the old docs Get started with Dgraph

I think this needs to be removed from docs after some checks. Today, what you can do is use expand type e.g: expand(Person)

UPDATE: Github Issue to track this Remove deprecated expand() feature from docs. · Issue #4561 · dgraph-io/dgraph · GitHub

@utekaravinash @MichelDiz I have raised a PR to update docs about expand function.
