ErrorView which is used to handle errors doesn’t provide conn or stuff like that. Is there a way to attach layout anyway? Showing 404 error without any layout in current project is no-go. The only way i see at this moment is to copy all the markup from app.html.eex which is less than ideal solution…

Also, it’s possible to add wildcard route at the end of every relevant section in router.ex, this is half of the solution. The other half would be catching “not found” exceptions (or something like this). As far as i know FallbackController doesn’t work with exceptions?

Thank you. That’s what i was looking for. Hard to find :frowning: For history, solution looks like this: defmodule AppWeb.ErrorView do use AppWeb, :view def render("404.html", assigns) do Phoenix.View.render_layout AppWeb.LayoutView, "app.html", assigns do render("not_found.html", a…

Thanks for positing the solution @thousandsofthem - it really helped me in arriving at my own version of solving this problem. This is what I went with: defmodule AppWeb.ErrorView do use AppWeb, :view def template_not_found(template, assigns) do render( "error.html", Map.put(as…

config :demo, DemoWeb.Endpoint, render_errors: [ view: DemoWeb.ErrorView, accepts: ~w(json), root_layout: false, layout: false ] Phoenix.Endpoint has an option called render_errors, you can set root_layout or layout in config.

[image] c4710n: Phoenix.Endpoint has an option called render_errors, you can set root_layout or layout in config. I set root_layout and layout to true and here’s what i got: Server: localhost:4000 (http) Request: GET /wrong/pathname ** (exit) an exception was raised: ** (RuntimeError) ca…

You can’t set them to true. Internally, it will call Controller.put_root_layout and Controller.put_layout. Inspect the source code at here: phoenix/lib/phoenix/endpoint/render_errors.ex at 67f0083911e55fde971be56ec3d4d5d233377db6 · phoenixframework/phoenix · GitHub Because of that, you should set …

[image] c4710n: Because of that, you should set something like: should i pass this tuple in render_errors from config.exs? where? sorry im lost with this part.

Setting it in config.exs would be fine. For example: config :demo, DemoWeb.Endpoint, render_errors: [ accepts: ~w(html json), root_layout: {DemoWeb.LayoutView, :error}, layout: {DemoWeb.LayoutView, :skip}, view: DemoWeb.ErrorView, ], # ... {DemoWeb.LayoutView, :error} corre…

Ah! makes sense now. All that’s left is fixing missing conn keys from my menu bar. Thanks alot for helping out!
