[MODEL]  
type Person {  
pname string  
}  
type Car {  
color string  
link Person  
}  
pname: string @index(exact) .  
color: @string @index(exact) .  
link: uid @reverse .

I want to query one car’s all info by pname, BUT the query not work  
{  
node(func: eq(pname, “wZGWuMneOg”)) {  
~link{  
tar as uid  
}  
}  
q(func: uid(tar)) @recurse{  
expand(_all_)  
}  
}

FYI  
The official user guide is so unfriendlly and example is too less. Really want to give up using DGraph

Are you using DQL with a GrapQL schema? How did you input/mutate your data?

Finally, in order to get backward edges, I use “big wild table”, each real table link to TABLE TABLE.

* * *

so the input like this,  
{  
q(func: eq(actor\_name, “Bruce Lee”)) {  
~movie\_actor {  
tar as uid  
}  
}  
query(func: uid(tar)) {  
expand(_all_) {  
expand(_all_)  
}  
}  
}

* * *

FYI. My data models like this:

\_:actor \<actor\_name\> “Bruce Lee” .  
\_:actor \<dgraph.type\> “Actor” .  
\_:director \<director\_name\> “Sp” .  
\_:director \<dgraph.type\> “Director” .  
\_:car \<car\_model\> “Tesla” .  
\_:car \<dgraph.type\> “Car” .  
\_:staff \<staff\_name\> “Andy” .  
\_:staff \<dgraph.type\> “Staff” .  
\_:tag \<tag\_name\> “Comedy” .  
\_:tag \<dgraph.type\> “Tag” .  
\_:movie \<movie\_name\> “Q” .  
\_:movie \<dgraph.type\> “Movie” .  
\_:movie \<movie\_actor\> \_:actor .  
\_:movie \<movie\_director\> \_:director .  
\_:movie \<movie\_staff\> \_:staff .  
\_:movie \<movie\_tag\> \_:tag .  
\_:staff \<staff\_car\> \_:car .

As you saw, Each Type links to MOVIE type, as Two Level Tree

So, I could get whole relevant data by inputing only three conditions which are “actor\_name,” “Bruce Lee” and “movie\_type” in my java/go code.

BTW, why “_forward_” is deprecated?

Thanks.
