首先,在我的请求规范sites.spec.rb
中,我进行了此测试:
describe "POST /v1/sites" do
let(:valid_attributes) { { url: "www.example.com", site_code: "123456" } }
context 'when the request is valid' do
before { post v1_sites_path, params: valid_attributes }
it 'creates a site' do
expect(json['url']).to eq("www.example.com")
expect(json['site_code']).to eq("123456")
end
it 'returns status code 201' do
expect(response).to have_http_status(201)
end
end
然后我对“创建网站”进行了失败的测试......
1) Sites POST /v1/sites when the request is valid creates a site
Failure/Error: expect(json['url']).to eq("www.example.com")
expected: "www.example.com"
got: ["can't be blank"]
(compared using ==)
# ./spec/requests/sites_spec.rb:61:in `block (4 levels) in <top (required)>'
# ./spec/rails_helper.rb:84:in `block (3 levels) in <top (required)>'
# ./spec/rails_helper.rb:83:in `block (2 levels) in <top (required)>'
现在这在技术上是有道理的,因为我的Site模型有验证:url,:site_code,presence:true。所以测试失败了,因为帖子没有正确地传递参数。
最后,这是控制器:
module Api::V1
class SitesController < BaseApiController
before_action :set_site, only: [:show, :update, :destroy]
# GET /sites
def index
@sites = Site.all
render json: @sites
end
# GET /sites/1
def show
render json: @site
end
# POST /sites
def create
@site = Site.new(site_params)
if @site.save
render json: @site, status: :created, location: @site
else
render json: @site.errors, status: :unprocessable_entity
end
end
# PATCH/PUT /sites/1
def update
if @site.update(site_params)
render json: @site
else
render json: @site.errors, status: :unprocessable_entity
end
end
# DELETE /sites/1
def destroy
@site.destroy
end
private
# Use callbacks to share common setup or constraints between actions.
def set_site
@site = Site.find(params[:id])
end
# Only allow a trusted parameter "white list" through.
def site_params
# params.require(:data).require(:attributes).permit(:url, :side_code, :user_id)
# params.require(:site).permit(:url, :side_code, :user_id)
params.fetch(:site, {}).permit(:url, :side_code)
end
end
end
我猜测我将参数传递给Rails API的帖子的方式可能没有格式化或正确或完全不同。我尝试使用测试块中的params
来尝试数据:{attributes:valid_attributes}但没有运气。
非常感谢任何想法或建议!
答案 0 :(得分:0)
这个问题确实是由于我在测试块中传递给POST请求的参数格式。我通过命令行测试了POST,并观察了rails服务器,看看params是如何通过的。它们看起来像这样:
Parameters: {"site_code"=>"123456", "url"=>"www.updated.com", "subdomain"=>"api", "id"=>"2", "site"=>{"site_code"=>"123456", "url"=>"www.updated.com"}}
然后在我的sites_spec.rb中,我将此格式复制为帖子请求的有效参数:
let(:valid_attributes) { { "site"=>{"url"=>"www.example.com", "user_id"=>user_id, "site_code"=>"123456"} } }
这很有效。 params的JSON格式需要在测试块中格式化,就像它是真正的JSON请求一样。
