Hi everyone, I am trying to use Ecto.insert, and i have the following error : [error] #PID<0.416.0> running GORprojectWeb.Endpoint (cowboy_protocol) terminated Server: localhost:4000 (http) Request: POST /api/rooms ** (exit) an exception was raised: ** (FunctionClauseError) no function clause …

error is sent to my fallbackController : defmodule GORprojectWeb.FallbackController do @moduledoc """ Translates controller action results into valid `Plug.Conn` responses. See `Phoenix.Controller.action_fallback/1` for more details. """ use GORprojectWeb, :controller def call(conn, {…

Fall back controller is okay but its better if you use the error_view file for displaying changeset errors. def render("errors.json", %{code: code, message: message, changeset: changeset}) do %{error: %{code: code, message: message, errors: translate_errors(changeset)}} end def translate_e…

I added your code in my error_view.ex, and it seems like the error is not handled there. From the stacktrace it seems that it goes from room_controller directly to changeset_view, in which there is : def translate_errors(changeset) do Ecto.Changeset.traverse_errors(changeset, &translate_error…

From stacktrace it seems like in error helpers the translate_error function is not working for your is invalid message. You are passing one argument but it accepts 2 arguments.

I totally agree with you, and this is where i do not understand. In my errors.pot, i have the following code : ## From Ecto.Changeset.put_change/3 msgid "is invalid" msgstr "" According to this thread , it should be working

what is your goal? What you trying to implement?

I am trying to understand why this error is raised, how to handle it properly, and of course i am trying to fix the Repo.insert error note that the error is not raised anymore if i delete father: {} inside def create_room(attrs \\ %{}) do %Room{children: [], father: {}, users: []} |> Roo…

Add IO.inspect after |> Room.changeset(attrs) def create_room(attrs \\ %{}) do %Room{children: [], father: {}, users: []} |> Room.changeset(attrs) |> IO.inspect() |> Repo.insert() end And see what it gives you in the console. After you run this method

i’ve put two IO.inspect : def create_room(attrs \\ %{}) do %Room{children: [], father: {}, users: []} |> Room.changeset(attrs) |> IO.inspect() |> Repo.insert() |> IO.inspect() end and i have : [info] POST /api/rooms [debug] Processing with GORprojectWeb.RoomController.crea…
