Connections in graphql for pagination - pagination

Question

I am new to graphql and am trying to learn how connections work for pagination. I am following documentation here: https://graphql-ruby.org/pagination/using_connections.html.
I am able to use connection_type to view say User in graphiql.
field :allUsers, Type::MyUsers.connection_type, null: false
def allUsers
Users.all
end
I am not able to understand how to write code in Make connection fields and Return collections as per the documentation if I want to see the User-Post data.
For Users-Post relation, I have nested the return type in Type::MyUsers, something like:
class myUsers < GraphApi::BaseObject
field :name, String, null: false
field :created_at, GraphQL::Types::ISO8601DateTime, null: true
field :userPosts, Types::myPosts.connection_type, null: true
end
How do I get the data in posts so that when I see in graphiql the result should be something like:
query {
users {
pageInfo {
hasNextPage,
endCursor
}
edges {
node {[
{name : "User1",
userPosts {
edges {
nodes{ [
{body: "post1"},
{body: "post2"}
]
}
}
}},
{name : "User2",
userPosts {
edges {
nodes{ [
{body: "post12"},
{body: "post22"}
]
}
}
}}
]
}
}
}
}

SOLN: The only piece missing was:
class myUsers < GraphApi::BaseObject
field :name, String, null: false
field :created_at, GraphQL::Types::ISO8601DateTime, null: true
field :userPosts, Types::myPosts.connection_type, null: true
def userPosts
object.posts
end
end
There was a typo in the resolver name and hence it did not work 🙃
