Ecto: ** (UndefinedFunctionError) undefined function: SomeModel.__schema__/1

In the following code, the function find_all_channels fails with the error:

** (exit) an exception was raised:
    ** (UndefinedFunctionError) undefined function: Application.__schema__/1
        (elixir) Application.__schema__(:source)

That's because you are using Elixir's Application module instead of your Slacker.Application. My suggestion: call it something else to avoid confusion.

I had a issue in my Repo.insert , I defined as previously in User model
` schema "users" do

has_many(:authorize_tokens, AuthorizeToken)

timestamps()

end`

When I was calling this function
changeset = User.changeset(%User{}, user_params) case Repo.insert(changeset) do {:ok, _user} -> conn |> put_flash(:info, "User created successfully.") |> redirect(to: user_path(conn, :index)) {:error, changeset} -> render(conn, "new.html", changeset: changeset) end

It is producing following error

function AuthorizeToken.__schema__/1 is undefined (module AuthorizeToken is not available)

I only add one thing in my model

alias BlogTest.AuthorizeToken

Now everything is working fine

I just experienced this and I spent a little longer than I wanted to resolve it so here's some info, FWIW...

This can occur if there is a naming conflict between modules. e.g. you have a schema Foo and another module also named Foo.

Check if you have any naming conflicts!
