Hi forum!
I’m quite new to elixir and phoenix and really like it so far. But there’s one thing I don’t understand, here’s my code:
Mutation:
def change do
create table(:things) do
add :int_data, {:array, :int}
add :error, :string
timestamps()
end
Ecto module
schema "things" do
field :error, :string
field :int_data, {:array, :int}
timestamps()
end
How is the correct changeset implementation for it?
def changeset(observation, attrs) do
observation
|> cast(attrs, [:error, :int_data])
end
results in
** (UndefinedFunctionError) function :int.cast/1 is undefined or private
:int.cast(22)

for input [22, 25, 80, 443, 587, 993]
Thank you in advance!
