Ecto Changeset validate_confirmation function is undefined
This related to my other question, but I’m asking a new one for clarity.
Using the built-in validation_confirmation I’m getting:
undefined function validate_confirmation/4.
It’s an Ecto(?) function, so I’m stumped on this one. None of the other functions there fail, only validation_confirmation. Am I missing an import somewhere? Undefined error makes no sense here.
defp validate_email(changeset) do
IO.inspect(changeset)
changeset
|> validate_required([:email])
|> validate_format(:email, ~r/^[^\s]+@[^\s]+$/, message: "must have the @ sign and no spaces")
|> validate_length(:email, max: 160)
|> unsafe_validate_unique(:email, TurnStile.Repo)
|> unique_constraint(:email)
|> validate_confirmation(changeset, :password, message: "does not match password")
end

It does take the changeset as a first parameter, it’s just that the pipe removes the need to type it out.
Example:
def sum(a, b) do
a + b
end
# the two lines below do the same thing:
sum(1, 2)
1 |> sum(2)

defp validate_email(changeset) do
IO.inspect(changeset)
changeset
|> ...
|> validate_confirmation(changeset, :password, message: "does not match password")
end
What you had originally would be equivalent to:
validate_confirmation(changeset, changeset, :password, message: "...")
which would explain why the error was undefined function validate_confirmation/4.
