How to create a Relay edge?
Say my schema defines a todo object and a todos Relay connection. Right now there are methods like Absinthe.Relay.Connection.from_query to help create resolve that connection. And it works great.
My question is if I have a Relay mutation payload field :add_todo which returns a todo edge, is there any helper method for building that edge? Or we can do this by hand?

It seems strange to answer a create mutation with a relay edge instead of a todo item.
Could You show your resolver?

Thanks for the reply. But I don’t see why it’s strange. 
The official relay example actually does this. That seems the only way to add to a connection?
I actually figured out a way, assuming the new todo is added to the end:
def some_resolver(_, args, _) do
todo = SomeContext.create_todo(args)
count = Repo.aggregate Todo, :count, :id
offset = count - 1
cursor = Absinthe.Relay.Connection.offset_to_cursor(offset)
{:ok, %{todoEdge: %{cursor: cursor, todo: todo}}
end
