Now is possible to use embedded_schema instead of schema, it means, there is no database requirement (but still Ecto is required).
I know that using embedded schemas in that way is kinda hack, so I’m not proud of it. But it was very easy to implement.
Example:
defmodule App.Registration do
use App.Web, :model
embedded_schema do # instead of `schema "table_name"`
field :email
field :password
end
end
defmodule App.RegistrationType do
use Formex.Type
def build_form(form) do
form
|> add(:email, :text_input, label: "E-mail")
|> add(:password, :password_input, label: "Password")
|> add(:save, :submit, label: "Register")
end
end
Controller
def register(conn, %{"registration" => registration_params}) do
RegistrationType
|> create_form(%Registration{}, registration_params)
|> handle_form # new function
|> case do
{:ok, registration} ->
# do something with the `registration`
{:error, form} ->
# display errors
render(conn, "index.html", form: form)
end
end
