如何解决Rails 请求规范 - nil:NilClass (rswag) 的未定义方法“body”
我正在尝试使用 rwsag 生成 API 文档,但我对我的一些规范失败感到困惑。
这是我的请求规范:-
require 'swagger_helper' ### this includes 'rails_helper'
RSpec.describe 'api/v1/users',type: :request do
before(:each) { host! 'localhost:3001' }
path '/api/v1/users' do
post('create user') do
tags 'users'
consumes 'application/json'
parameter name: :user,in: :body,schema: {
type: :object,properties: {
title: { type: :string },description: { type: :string },date: { type: :datetime },budget: { type: :decimal },awarded: { type: :boolean }
},required: [ 'title','description' ]
}
response(200,'successful') do
after do |example|
example.Metadata[:response][:content] = {
'application/json' => {
example: JSON.parse(response.body,symbolize_names: true)
}
}
end
run_test!
end
end
end
以下是我认为没有多大意义的两个错误:-
1) api/v1/users /api/v1/users post successful returns a 200 response
Got 0 failures and 2 other errors:
1.1) Failure/Error: super
NoMethodError:
undefined method `user' for #<RSpec::ExampleGroups::ApiV1Users::ApiV1Users::Post::Successful:0x0000aaaad7d06600>
# /usr/local/bundle/gems/rswag-specs-2.4.0/lib/rswag/specs/request_factory.rb:197:in `build_json_payload'
# /usr/local/bundle/gems/rswag-specs-2.4.0/lib/rswag/specs/request_factory.rb:180:in `add_payload'
# /usr/local/bundle/gems/rswag-specs-2.4.0/lib/rswag/specs/request_factory.rb:22:in `block in build_request'
# /usr/local/bundle/gems/rswag-specs-2.4.0/lib/rswag/specs/request_factory.rb:18:in `tap'

# /usr/local/bundle/gems/rswag-specs-2.4.0/lib/rswag/specs/example_group_helpers.rb:94:in `block in run_test!'
1.2) Failure/Error: example: JSON.parse(response.body,symbolize_names: true)
NoMethodError:
undefined method `body' for nil:NilClass
# ./spec/requests/api/v1/users_spec.rb:84:in `block (5 levels) in <main>'
还有我的标准控制器动作:-
module Api
module V1
class UsersController < ApplicationController
# POST /api/v1/users
def create
@user = Job.new(user_params)
if @user.save
render json: @user,status: :created
else
render json: @user.errors,status: :unprocessable_entity
end
end
知道是什么导致了这个错误吗?我也对生成的 rswag 规范结构有点困惑 - 即任何地方都没有 expects
。
解决方法
答案是我错过了下面的 let(:user)
行:-
response(201,'successful') do
after do |example|
example.metadata[:response][:content] = {
'application/json' => {
example: JSON.parse(response.body,symbolize_names: true)
}
}
end
let(:user) { { title: 'foo',description: 'bar' } }
run_test!
end
