我正在构建凤凰 1.3 应用,但是在 1.2 Pheonix教程之后,我运行了mix phoenix.gen.model
等已弃用的命令
我不确定它是否已链接,但现在我收到此错误:
== Compilation error in file lib/gazette_web/controllers/user_controller.ex ==
** (CompileError) lib/gazette_web/controllers/user_controller.ex:12: Gazette.User.__struct__/1 is undefined, cannot expand struct Gazette.User
lib/gazette_web/controllers/user_controller.ex:11: (module)
(stdlib) erl_eval.erl:670: :erl_eval.do_apply/6
(elixir) lib/kernel/parallel_compiler.ex:121: anonymous fn/4 in Kernel.ParallelCompiler.spawn_compilers/1
这是我的user_controller.ex文件:
defmodule Gazette.UserController do
use GazetteWeb, :controller
alias Gazette.User
def show(conn, %{"id" => id}) do
user = Repo.get!(User,id)
render(conn, "show.html", user: user)
end
def new(conn, _params) do
changeset = User.changeset(%User{})
render conn, "new.html", changeset: changeset
end
def create(conn, %{"user" => user_params}) do
# here will be an implementation
end
end
这是我的model / user.ex文件:
defmodule Gazette.User do
use Gazette.Web, :model
schema "users" do
field :email, :string
field :name, :string
field :password, :string, virtual: true
field :password_hash, :string
field :is_admin, :string
field :is_writer, :string
has_many :posts, Gazette.Post
timestamps()
end
@required_fields ~w(email name)a
@optional_fields ~w(is_admin is_writer)a
@doc """
Builds a changeset based on the `struct` and `params`.
"""
def changeset(struct, params \\ %{}) do
struct
|> cast(params, @required_fields ++ @optional_fields)
|> validate_required(@required_fields)
end
end
任何想法?
答案 0 :(得分:3)
您的public class CustomersController : ApiController
{
[Route("api/v2/customers", Order = 2)]
[ResponseType(typeof(CustomerCollection))]
public IHttpActionResult Get()
{
...
}
[Route("api/v2/customers/{identifier}", Order = 1)]
[ResponseType(typeof(Customer))]
public IHttpActionResult Get(string identifier)
{
...
}
}
是一个常规模块,它不会自动转向结构。要制作Gazette.User
架构,您需要:
Ecto
我不确定use Ecto.Schema
做了什么,但我相信它已被弃用或其他什么。在定义模式时,最好是明确的。
您可能还需要/需要:
use Gazette.Web, :model
此代码可能已使用旧import Ecto.Changeset
import Ecto.Query
任务自动生成。相反,您希望使用mix phx.gen.model
来获取正确的样板。
