常见的想当然

An Ecto query binding list must name every intermediate join, so `[first, ..., last]` cannot select the outer bindings.

这是本样本作者记下的、开发者或模型在此处通常会有的预期。下面的契约才是真正运行过的东西。

契约

• assert a query with two joins compiles when a follow-up from expression uses the binding list [first, ..., last]
• assert the resulting select expression refers to binding indexes 0 and 2, selecting the first source and final join
