I am trying to make a site on which users can login and see there information and possibly even change that information. I already made it so that everything CRUD wise works (that is for admin users) however I try to now make it so that users can see their own profile but i keep getting this error:
Phoenix.ActionClauseError at GET /users/1 no function clause matching in DieterDierenWeb.UserController.show/2

Despite this being fully possible through admin resources (see below).
This is my router file (as you can see there is also an admin scope with resources and i can indeed do this properly as admin by just going to /admin/users/1:
> defmodule DieterDierenWeb.Router do use DieterDierenWeb, :router
>
> pipeline :browser do
> plug :accepts, ["html"]
> plug :fetch_session
> plug :fetch_flash
> plug :protect_from_forgery
> plug :put_secure_browser_headers end
>
> pipeline :api do
> plug :accepts, ["json"] end
>
> pipeline :auth do
> plug DieterDierenWeb.Pipeline end
>
> pipeline :ensure_auth do
> plug Guardian.Plug.EnsureAuthenticated end
>
> pipeline :allowed_for_users do
> plug DieterDierenWeb.Plugs.AuthorizationPlug, ["Admin", "User"] end
>
> pipeline :allowed_for_admins do
> plug DieterDierenWeb.Plugs.AuthorizationPlug, ["Admin"] end
>
> scope "/", DieterDierenWeb do
> pipe_through [:browser, :auth]
>
> get "/", SessionController, :new
> get "/login", SessionController, :new
> post "/login", SessionController, :login
> get "/logout", SessionController, :logout
> get "/users/new", UserController, :show_sign_up
> post "/users/new", UserController, :sign_up end
>
> scope "/", DieterDierenWeb do
> pipe_through [:browser, :auth, :ensure_auth, :allowed_for_users]
>
> get "/users/:user_id", UserController, :show
> get "/user_scope", PageController, :user_index end
>
> scope "/admin", DieterDierenWeb do
> pipe_through [:browser, :auth, :ensure_auth, :allowed_for_admins]
>
> resources "/users", UserController end # Other scopes may use custom stacks. # scope "/api", DieterDierenWeb do # pipe_through

This is my controller file the show function should show the profile page on the basis of the currently logged in user but here it gives the error:
defmodule DieterDierenWeb.UserController do
use DieterDierenWeb, :controller

end

changeset = UserContext.change_user(%User{})
roles = UserContext.get_acceptable_roles()
render(conn, "new.html", changeset: changeset, acceptable_roles: roles)
end
def show_sign_up(conn, _params) do
changeset = UserContext.change_user(%User{})
roles = UserContext.get_acceptable_roles()
render(conn, "sign_up.html", changeset: changeset, acceptable_roles: roles)
end

end
end
def show(conn, %{"id" => id}) do
user = UserContext.get_user!(id)
render(conn, "show.html", user: user)
end
def edit(conn, %{"id" => id}) do

changeset = UserContext.change_user(user)

end
def update(conn, %{"id" => id, "user" => user_params}) do

end
I will also give you the nav I use to try and navigate to the profile page:

Since I am quite new to this and since it says the first parameter is from my plug I will also give you the plug file no idea if this is helpfull or not though:
defmodule DieterDierenWeb.Plugs.AuthorizationPlug do
import Plug.Conn
alias DieterDieren.UserContext.User
alias Phoenix.Controller
def init(options), do: options
def call(%{private: %{guardian_default_resource: %User{} = u}} = conn, roles) do
conn
|> grant_access(u.role in roles)
end
def grant_access(conn, true), do: conn
def grant_access(conn, false) do
conn
|> Controller.put_flash(:error, "Unauthorized access")
|> Controller.redirect(to: "/")
|> halt
end
end
Can anyone please help me find my error?
