I’m creating an api that inserts new user. Rendering the error from Ecto Changeset is what I want to do using JSON. It doesn’t seem to work. For example: username already taken or email already taken.
Below is the create function
def create(conn, %{"user" => user_params}) do
case Accounts.create_user(user_params) do
{:ok, token, _claims} ->
Accounts.create_user(user_params)
conn
|> render("jwt.json", jwt: token)
{:error, changeset} ->
IO.inspect(changeset.errors)
conn
|> put_status(:unauthorized)
|> put_view(FakeWeb.ErrorView)
|> render("error.json", changeset: changeset)
end
end
Below is the error render
def translate_errors(changeset) do
Ecto.Changeset.traverse_errors(changeset, &translate_error/1)
end
def render("error.json", %{changeset: changeset}) do
# When encoded, the changeset returns its errors
# as a JSON object. So we just pass it forward.
%{errors: translate_errors(changeset)}
end
I get a 401 response but want something also like
errors: {email: has already been taken}
Ecto changeset struct is below:
#Ecto.Changeset<
action: :insert,
changes: %{
confirmed: false,
email: "H@gmail.com",
is_active: false,
is_staff: false,
password: "fakepass",
password_hash: "$2b$12$uKZUqpqUW2IJ48japUNoqeWIIGsNhDA97N/6VA.5ZF6f8jRtjOpm6",
username: "Charle"
},
errors: [
email: {"has already been taken",
[constraint: :unique, constraint_name: "users_email_index"]}
],
data: #Fake.Accounts.User<>,
valid?: false
>
