Say I have this kind of structure
A (collection): {
a (doc): {
name:'Tim',
B (collection):{
b (doc): {
color:'blue'
}
}
}
}
where A
and B
are collections while a
and b
are documents.
Is there a way to get everything contained in a root document with one query?
If I query like this
db.collection("A").doc("a").get()
I just gets name:'Tim'
field. What I want is to also get all B's documents.
I basically wish my query returns
{
user:'Tim',
B (collection):{
b (doc): {
color:'blue'
}
}
}
Is it possibly or do I really need to make multiple queries one for each collection :/ ?
Say I have a really deep nested tree of collections representing the user profile, my costs will raise like hell since each time I load a user profile I have a multiplier of read requests 1 x N
where N is the depth of my tree :/.
B
? There is a reference type you could try. – JonZarate
