Phx.gen.json API route undefined after added to router.ex

I think it should be

  scope "/api", HaaksploitsWeb do
    pipe_through :api
    ...
  end
  
  scope "/", HaaksploitsWeb do
    pipe_through :browser # Use the default browser stack
    ...
  end

You might also show page_content_controller.ex because the error is inside.

Probably routes.jelper not imported.

Hhhhhmmm. I changed to /api but it’s the same.

page_content.controller.ex:

defmodule HaaksploitsWeb.PageContentController do
  use HaaksploitsWeb, :controller

  alias Haaksploits.PageData
  alias Haaksploits.PageData.PageContent

  action_fallback HaaksploitsWeb.FallbackController

  def index(conn, _params) do
    pagecontent = PageData.list_pagecontent()
    render(conn, "index.json", pagecontent: pagecontent)
  end

  def create(conn, %{"page_content" => page_content_params}) do
    with {:ok, %PageContent{} = page_content} <- PageData.create_page_content(page_content_params) do
      conn
      |> put_status(:created)
      |> put_resp_header("location", page_content_path(conn, :show, page_content))
      |> render("show.json", page_content: page_content)
    end
  end

  def show(conn, %{"id" => id}) do
    page_content = PageData.get_page_content!(id)
    render(conn, "show.json", page_content: page_content)
  end

  def update(conn, %{"id" => id, "page_content" => page_content_params}) do
    page_content = PageData.get_page_content!(id)

    with {:ok, %PageContent{} = page_content} <- PageData.update_page_content(page_content, page_content_params) do
      render(conn, "show.json", page_content: page_content)
    end
  end

  def delete(conn, %{"id" => id}) do
    page_content = PageData.get_page_content!(id)
    with {:ok, %PageContent{}} <- PageData.delete_page_content(page_content) do
      send_resp(conn, :no_content, "")
    end
  end
end

It was autogenned by the phx client, but I am seeing this error in my IDE next to the HaaksploitsWeb, :controller line:

(CompileError) module HaaksploitsWeb.Router.Helpers is not loaded and could not be found

I’ve seen this error a few times when doing various things with my app and it often seems to go away when I reclone the repo, but not this time.

Yes, that does seem to be what’s happened, but why does this keep occurring and how do I stop it?

As far as I remember that module gets created when compiling the router as well. Please do a mix clean and a mix build and show full transcript of the latter.

Please reinstall the mix archive of your project it causes module clashes.

Then try again.

Running mix do archive.build, archive.install results in the same error.

I meant remove, sorry for the confusion.

I’d try doing an rm -rf _build
