我试图从我的帐户域中获取方法。我可以使用Accounts
中iex
域中的任何方法,mark_as_admin/1
(最后一个)除外。
这是域名
defmodule Storex.Accounts do
import Ecto.Query, warn: false
alias Storex.Repo
alias Storex.Accounts.User
def create_user(attrs \\ %{}) do
%User{}
|> User.changeset(attrs)
|> Repo.insert()
end
def get_user!(id) do
Repo.get!(User, id)
end
def new_user() do
User.changeset(%User{}, %{})
end
def authenticate_user(email, password) do
Repo.get_by(User, email: email)
|> User.check_password(password)
end
def mark_as_admin(user) do
user
|> User.admin_changeset(%{is_admin: true})
|> Repo.update()
end
end
这是我在iex
中输入的内容:
iex(1)> alias Storex.Accounts
iex(2)> user = Accounts.get_user!(7)
[debug] QUERY OK source="accounts_users" db=2.2ms
SELECT a0."id", a0."email", a0."full_name", a0."password_hash",
a0."is_admin", a0."inserted_at", a0."updated_at" FROM "accounts_users"
AS a0 WHERE (a0."id" = $1) [7]
%Storex.Accounts.User{__meta__: #Ecto.Schema.Metadata<:loaded,
"accounts_users">,
email: "test@user.tld", full_name: "Test User", id: 7,
inserted_at: ~N[2018-01-14 11:52:14.472928], is_admin: false, password: nil,

iex(3)> Accounts.mark_as_admin(user)
** (UndefinedFunctionError) function Storex.Accounts.mark_as_admin/1 is

(storex) Storex.Accounts.mark_as_admin(%Storex.Accounts.User{__meta__:
#Ecto.Schema.Metadata<:loaded, "accounts_users">, email:
"test@user.t~ld", full_name: "Test User", id: 7, inserted_at:
~N[2018-01-14 11:52:14.472928], is_admin: false, password: nil,

为什么我不能称这种方法?
编辑:
重新启动iex
后,域名中的方法将无法再被调用:
iex(1)> alias Storex.Accounts
Storex.Accounts
iex(2)> Accounts.get_user!(7)
** (UndefinedFunctionError) function Storex.Accounts.get_user!/1 is
undefined or private
答案 0 :(得分:2)
您应该从项目的根目录启动IEx,例如
iex -S mix
。
如果您编辑并保存代码,则应以相同方式重新启动IEx,致电recompile()
或reload any single modules您已更改了要使用的内容,例如:
iex> recompile() # recompiles and reloads everything except mix.exs and configs
iex> r Storex.Accounts # recompiles and reloads a single module
