Question

在使用CURL发布帖子为我的API创建资源（以RoR编码）时，我在将哈希数组作为参数传递时遇到了一些麻烦。

我有以下JSON，我试图将其用作POST主体的指南：

{
  status: 200,
  show: {
    id: 2,
    creator_id: 2,
    venue_id: 2,
    name: "Rock Rumble",
    description: "Another fake event",
    created_at: "2016-02-25T00:21:36.343Z",
    updated_at: "2016-02-25T00:21:36.812Z"
  },
  artists: [{
    id: 5,
    name: "Finntroll",
    created_at: "2016-02-25T00:21:36.462Z",
    updated_at: "2016-02-25T00:21:36.462Z"
  }, {
    id: 6,
    name: "Moonsorrow",
    created_at: "2016-02-25T00:21:36.474Z",
    updated_at: "2016-02-25T00:21:36.474Z"
  }, {
    id: 7,
    name: "Amon Amarth",
    created_at: "2016-02-25T00:21:36.486Z",
    updated_at: "2016-02-25T00:21:36.486Z"
  }, {
    id: 8,
    name: "Satyricon",
    created_at: "2016-02-25T00:21:36.498Z",
    updated_at: "2016-02-25T00:21:36.498Z"
  }],
  showURL: "/api/shows/2",
  venueURL: "/api/venues/2"
}

我的Show.rb文件如下所示：

belongs_to :creator
belongs_to :venue
has_many :setlists
has_many :artists, :through => :setlists
validates :name,        presence: true
validates :description, presence: true

和Setlist这样：

class Setlist < ActiveRecord::Base
belongs_to :artist
belongs_to :show
end

最后艺术家是这样的：

class Artist < ActiveRecord::Base
has_many :setlists
has_many :shows, :through=> :setlists
validates   :name,                      presence: true
end

现在我的Api :: ShowsController就像

def create
    @show = Show.new(show_params.except[:artists])        
    #If there are any artists to be saved with this show
    if show_params[:artists].present?
        #loop through artists, create artist
    else
...
   end
end
...
#Validation of params
private
def show_params
params.require(:show).permit(:name, :description, artists: [:name])
end

我可以在没有艺术家的情况下发帖，但我想做的事情如下：

    curl \
-H "Accept: application/json" \
-H "Content-type: application/json" \
-X POST \
-d '{"name":"test", "description":"testing post to create", "artists":[{"name":"hey"}] }' \
https://[username].c9users.io/api/shows.json

那么，我如何允许一个嵌套的prop。，并在其中包含一个代表我的POST主体中的艺术家的哈希数组？我做错了什么？

实际上，show_params [：artists] .present？ ===错误。

您可以尝试使用show密钥在请求正文中包装您的json表示吗？由于您正在执行params.require(:show)，permit中的密钥应该由require指定的密钥包装。

像：

{"show":{"name":"test", "description":"testing post to create", "artists":[{"name":"hey"}]}}

无法获得强大的参数＆amp; POST w。 CURL工作（Ruby on Rails）
