I have read phoenix documents and edited my code but it didn’t work for me. my dev config : config :trangell_html_site_web, TrangellHtmlSiteWeb.Endpoint, http: [port: 9991], debug_errors: false, code_reloader: true, check_origin: false, watchers: [node: ["node_modules/brunch/bin/brunch", "watch", "--stdin", cd: Path.expand("../assets", __DIR__)]] my ErrorView : def render("404.html", _assigns) do "Page not found" end def render("500.html", _assigns) do "Server internal error" end def template_not_found(template, _assigns) do Phoenix.Controller.status_message_from_template(template) end but it shows me : [55%20pm] How can I fix this ? ref https://hexdocs.pm/phoenix/errors.html https://hexdocs.pm/phoenix/views.html#the-errorview phoenix 1.3 || elixir v1.6.4

That’s a bit weird, just tested on a new app (generated with phx.new task) and it’s working fine… Only thing I changed was the debug_errors option to false as you did. Can you provide an example repo to reproduce the issue?

What is your Elixir version? There is a bug in Elixir before v1.7 where a change of configuration inside the umbrella project was not applying in some cases. If you remove _build at the umbrella root, does the issue still persists?

@josevalim Unfortunately, I have a problem with this part, I want to redirect to html error page but I can’t defmodule TrangellHtmlSiteWeb.ErrorView do use TrangellHtmlSiteWeb, :view # If you want to customize a particular status code # for a certain format, you may uncomment below. def render("404.html", _assigns) do "Page not found" end def render("500.html", _assigns) do "Server internal error" end # In case no render clause matches or no # template is found, let's render it as 500 def template_not_found(_template, assigns) do render "500.html", assigns end def template_not_found(template, _assigns) do Phoenix.Controller.status_message_from_template(template) end end I edited this to def render("404.html", _assigns) do render "404.html", %{} end but it didn’t work, how can I fix this?

[image] shahryarjb: I edited this to def render("404.html", _assigns) do render "404.html", %{} end This produces an infinite loop.

Then what do I do to fix this? would you mind telling me? Please

What is it you actually want? If you want some HTML template rendered, then do so. As far as I remember you simply need to provide the template in the template/error folder and then leave off the render clause.

Hmm, Im confused, honestly I need it to show my 404.html.eex instead of text, I have created 2 html .eex before, but I can’t use these. for example: 404 - Page Not Found "> 404 - Page Not Found This isn't the page you were looking for. that is my web/templates/error/404.html.eex , but It isn’t shown when I enter broken url. it shows me a text but I want that. Updated: now I know, I have to delete all of my codes in My ErrorView except the following line: def template_not_found(template, _assigns) do Phoenix.Controller.status_message_from_template(template) end I have 2 questions q1: when I have 401 or 403 status; What is happens? can I custom them ? q2: I have a FallbackController please see my code: defmodule TrangellHtmlSiteWeb.BlogFallbackController do use Phoenix.Controller def call(conn, {:ok, %HTTPoison.Response{status_code: 404, body: _body}}) do conn |> put_flash(:info, "متاسفانه صفحه ای که به دنبال آن هستید وجود ندارد.") |> render(TrangellHtmlSiteWeb.ErrorView , :"404") end end I render render(TrangellHtmlSiteWeb.ErrorView , :"404") and it shows me an error in centre of my template, but in the main page if I try like: local.com/404 it just shows me full 404 error page, independently!! Please see: pic 1: [21%20pm] pic2: [28%20pm] how can I redirect it to 404full page with the session which I need?

somebody knows what my problem is? I was forced to use redirect(conn, to: "/404") path: controllers/blog_fallback_controller.ex def call(conn, {:ok, %HTTPoison.Response{status_code: 404, body: _body}}) do conn |> put_flash(:info, "متاسفانه صفحه ای که به دنبال آن هستید وجود ندارد.") |> redirect( to: "/404") end and × 403 - Page Not Found This isn't the page you were looking for. get_flash doesn’t work and I can’t use session, what do I do ? ** (exit) an exception was raised: ** (ArgumentError) flash not fetched, call fetch_flash/2 (phoenix) lib/phoenix/controller.ex:1236: Phoenix.Controller.get_flash/1 (phoenix) lib/phoenix/controller.ex:1250: Phoenix.Controller.get_flash/2
