Ecto doesn't save decimal value to correct precision

Hi,
I’m exploring Elixir and Phoenix framework.

I’m using phx.gen.html command to generate a simple CRUD resources. I’m using :decimal for price attract. And in the form html.eex, I use <%= number_input f, :price, step: "0.01". Apparently, updating this will always get rounded to integer.

Why is that?

Your example is incrementing price in steps of 0.01, so I’d start by setting scale to 2.

“Apparently”? Do you have a failing test? Can you show the changeset code along with sample inputs and output?
