Question

Has Ecto stopped supporting decimal-related options in schema field definition?

Error

Console error on mix compile --force (since updating ecto this morning)

Code

The ecto schema uses :decimal with extra options

field(:retail_price, :decimal, precision: 8, scale: 2)

** (ArgumentError) invalid option :precision for field/3
    (ecto 3.8.0) lib/ecto/schema.ex:2214: Ecto.Schema.check_options!/3
    (ecto 3.8.0) lib/ecto/schema.ex:1911: Ecto.Schema.__field__/4

Thanks
:pray:

Afaik those options were never supported on the field macro, but only on the add macro in migrations. Ecto only recently added code for validating those field options though.

Thanks, and you are a 100% right.
I just checked, and it does not enforce any validation based on that precision/scale prior Ecto3.8 when it compiled error-free.

  schema "test_schema" do
    field(:value, :decimal, precision: 2, scale: 2)
  end

  def changeset(schema, attrs) do
    cast(schema,  attrs, ~w(value)a)
  end


iex(35)> a = %{value: Decimal.new("222222.007000")}                
%{value: #Decimal<222222.007000>}

iex(36)> changeset %TestSchema{}, a                            
#Ecto.Changeset<
  action: nil,
  changes: %{value: #Decimal<222222.007000>},
  errors: [],
  data: #TestSchema<>,
  valid?: true
