Rails/AR - 如何在rspec中測試:: update（id，attributes）

Question

我正在使用活動記錄update方法來更新多個記錄，每個記錄具有各自的屬性。

我方便與此控制器代碼（工作）：

def update 
    keys = params[:schedules].keys 
    values = params[:schedules].values 
    if Schedule.update(keys, values) 
    flash[:notice] = "Schedules were successfully updated." 
    else 
    flash[:error] = "Unable to update some schedules." 
    end 
    respond_to do |format| 
    format.html { redirect_to responsibilities_path } 
    end 
end 

我的問題是，我怎麼能測試，如果沒有擊中RSpec的數據庫？

這是我正在嘗試，但它不工作。

describe "PATCH update" do 

    it "updates the passed in responsibilities" do 
    allow(Schedule) 
     .to receive(:update) 
     .with(["1", "2"], [{"status"=>"2"}, {"status"=>"1"}]) 
     .and_return(true) 
    # results in 
    # expected: 1 time with arguments: (["1", "2"], [{"status"=>"2"}, {"status"=>"1"}]) 
    # received: 0 times 
    # Couldn't find Schedule with 'id'=1 

    # without the allow, I get 
    # Failure/Error: patch :update, schedules: { 
    # ActiveRecord::RecordNotFound: 
    # Couldn't find Schedule with 'id'=1 
    # # ./app/controllers/responsibilities_controller.rb:18:in `update' 
    # # ./lib/authenticated_system.rb:75:in `catch_unauthorized' 
    # # ./spec/controllers/responsibilities_controller_spec.rb:59:in `block (5 levels) in <top (required)>' 

    patch :update, schedules: { 
     "1" => { 
     "status" => "2", 
     }, 
     "2" => { 
     "status" => "1", 
     } 
    } 
    expect(Schedule) 
     .to receive(:update) 
     .with(["1", "2"], [{"status"=>"2"}, {"status"=>"1"}]) 
    expect(flash[:error]).to eq(nil) 
    expect(flash[:notice]).not_to eq(nil) 
    end 
end 

我on Rails的4.2.4和RSpec 3.0.0

你的問題是，你與

expect(Schedule) 
     .to receive(:update) 
     .with(["1", "2"], [{"status"=>"2"}, {"status"=>"1"}]) 
     .and_call_original  

調用打補丁方法後期待。

這意味着請求在斷言建立之前命中您的控制器。 爲了解決這個問題，只需在補丁調用之前放置expect（Schedule）調用，這也可以讓您擺脫allow（Schedule）.to - call。

乾杯。
