I try as much as I can to use Dialyzer with my apps to help cut down on potential errors. One thing that I ran into was a bunch of warnings about not knowing how certain Ecto functions are defined. Of course since the Ecto library is (in a sense) a 3rd party library, I don’t want to see the warnings for that code. So a bit of digging turned up this great message thread about how to get Dialyzer working without having to constantly see warnings about not knowing what Ecto is.

Just felt like it was worth sharing in case others run into the same issue.
