phoenix view module not available - phoenix-framework

Question

My application works and api json requests and for regular html. My router.ex
defmodule MyApp.Router do
use MyApp.Web, :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
scope "/api", MyApp do
pipe_through :api # Use the default browser stack
scope "/v1", V1, as: :v1 do
resources "/users", UserController, except: [:new, :edit, :index]
end
end
scope "/", MyApp do
pipe_through :browser # Use the default browser stack
get "/confirm/:token", UserController, :confirm, as: :user_confirm
end
end
my web/controllers/v1/user_controller.ex
defmodule MyApp.V1.UserController do
use MyApp.Web, :controller
def create(conn, %{"user" => user_params}) do
...
conn
|> put_status(:created)
|> put_resp_header("location", v1_user_path(conn, :show, user))
|> render("sign_up.json", user: Map.put(user, :session, result[:session]))
...
end
and my web/controllers/user_controller.rb
defmodule MyApp.UserController do
use MyApp.Web, :controller
alias MyApp.User
def confirm(conn, %{"token" => token}) do
...
render(conn, "confirmed.html")
...
end
end
my web/views/v1/user_view.ex
defmodule MyApp.V1.UserView do
use MyApp.Web, :view
...
end
and my web/views/user_view.ex
defmodule MyApp.UserView do
use MyApp.Web, :view
end
Everything works fine until I added a route and a controller for html.
Now, when I make a request for api json, I get an error
Request: POST /api/v1/users
** (exit) an exception was raised:
** (UndefinedFunctionError) function MyApp.V1.UserView.render/2 is undefined (module MyApp.V1.UserView is not available)
But if I delete web/vews/user_view.ex, then this query works without errors.
How can you correct this error?

These types of errors can usually be resolved by running mix clean. You may also see this type of error during Live code reload in dev. It case, try restarting the Phoenix.Server, and if that does not help, run mix clean
