我打了这个电话:
curl -X POST -H "Content-Type: application/json" -d '{
"user": {
"email": "leo.hetsch@testapp.com",
"first_name": "Léo",
"last_name": "Hetsch",
"password": "notsosecure",
"username": "test1"
}
}' "http://localhost:4000/api/users"
在服务器上,我得到:
[info] POST /api/users
[debug] Processing by VirtualTeams.UserController.create/2
Parameters: %{"user" => %{"email" => "leo.hetsch@testapp.com", "first_name" => "Léo", "last_name" => "Hetsch", "password" => "[FILTERED]", "username" => "test1"}}
Pipelines: [:api]
这是我的用户.ex文件中:
schema "users" do
field :email, :string
field :password, :string
field :first_name, :string
field :last_name, :string
field :api_token, :string
field :username, :string
timestamps()
end
@doc """

def changeset(struct, params \ %{}) do
struct

|> validate_required([:email, :password, :first_name, :last_name, :api_token, :username])
|> unique_constraint(:email)

end
def create(params) do
changeset(%VirtualTeams.User{}, params)

|> VirtualTeams.Repo.insert()
end
defp hashed_password(password) do
Comeonin.Pbkdf2.hashpwsalt(password)
end
只是为了验证我做到了:
mix ecto.migrate
00:40:35.074 [info] Already up
为什么我会收到错误?
更新:忘记错误:
{"error":"error creating user"}
在我的控制器中,我有以下代码,其中有错误:
def create(conn, %{"user" => user_params}) do
case User.create(user_params) do
{:ok, user} ->
conn
|> put_status(:created)
|> render("user.json", user: user)
{:error, changeset} ->
conn
|> put_status(:bad_request)
|> json(%{error: "error creating user"})
end
问题似乎是changeset/2
需要:api_token
,但不存在于请求的参数中。
通常,查看 {:error, changeset}
中的changeset
(在本例中由 create/1
返回(以了解哪些验证失败很有用。
