Can you share your cast and cast_attachments code? Currently it is designed where you need to use cast_attachments for all file attributes only. All other attributes should still be sent through cast.

This is my model.

defmodule Mobil.Company do
  use Mobil.Web, :model
  use Arc.Ecto.Model

  schema "companies" do
    field :name, :string
    field :logo, Mobil.Logo.Type

    timestamps
  end

  @required_fields ~w(name)
  @optional_fields ~w(logo)

  @doc """
  Creates a changeset based on the `model` and `params`.

  If no params are provided, an invalid changeset is returned
  with no validation performed.
  """
  def changeset(model, params \\ :empty) do
    model
    |> cast_attachments(params, @required_fields, @optional_fields)
  end
end

So i need to split it up?

Yes, please split it up as such: https://github.com/stavro/arc_ecto/blob/master/test/model_test.exs#L21 and try again

Worked wonders! Thank you @stavro

I will do some digging to see if there is a less confusing way to handle this... You are not the first person to make this same hiccup

from arc_ecto.

MartinElvar commented on July 25, 2024

@stavro I don't know if i think that it is confusing, rather i would say the readme could be clearer.

More specific. https://github.com/stavro/arc_ecto#add-your-attachment-to-your-ecto-model

Which could explain it more like..

  schema "companies" do
    field :name, :string
    field :logo, Mobil.Logo.Type

    timestamps
  end

  @required_fields ~w(name)
  @optional_fields ~w()

  @doc """
  Creates a changeset based on the `model` and `params`.

  If no params are provided, an invalid changeset is returned
  with no validation performed.
  """
  def changeset(model, params \\ :empty) do
    model
    |> cast(params, @required_fields, @optional_fields)
    |> cast_attachments(params, ~w(), ~w(logo))
  end
