嗨我刚刚开始使用ruby,我正在编写控制器和控制器规格,但我有一些问题。
document.rb
class Document < ActiveRecord::Base
validates_presence_of :name
has_many :votes
end
documents_controller.rb
class API::DocumentsController < ApplicationController
def create
@document = Document.new(:name)
if @document.save
@document.update_attributes(name: @document.name.url) if document_params[:name].present?
render json: @document, serializer: DocumentSerializer, status: 201
else
render json: @document.errors, status: 422
end
end
end
documents_controller_spec.rb
describe "POST 'index'" do
before { @attr = FactoryGirl.attributes_for(:document) }
describe "failure" do
describe "with missing parameters" do
before { @attr.each { |key,value| @attr[key] = nil } }
it "should not create a new record" do
lambda { post :create, document: @attr }.should_not change(Document, :count)
end
end
end
end
但是,当我运行bundle exec rspec spec
试用我的测试时,我收到了一个错误:
Failure/Error: lambda { post :create, document: @attr }.should_not change(Document, :count)
ArgumentError:
When assigning attributes, you must pass a hash as an argument.
# ./app/controllers/api/documents_controller.rb:8:in `create'
# ./spec/controllers/api/documents_controller_spec.rb:29:in `block (6 levels) in <top (required)>'
# ./spec/controllers/api/documents_controller_spec.rb:29:in `block (5 levels) in <top (required)>'
任何人都可以对此有所了解吗?
答案 0 :(得分:8)
问题出在您的控制器中。
def create
@document = Document.new(:name) # :name is a symbol, not a Hash like params for example
