views

问题 I know materialized view and I'm using it. I have never used indexed views but I will. What are the differences between them ? 回答1: SQL Server’s indexed views are always kept up to date. In SQL Server, if a view’s base tables are modified, then the view’s indexes are also kept up to date in the same atomic transaction. Oracle provides something similar called a materialized view. If Oracle’s materialized views are created without the **REFRESH FAST ON COMMIT** option, then the materialized

问题 I'm testing a view with RSpec (2.12 on Rails 3.2.8). I'm using CanCan to conditionally display certain elements on a page. This requires a controller method 'current_user'. In some of my specs I've been able to stub out current_user, eg. controller.stub(:current_user).and_return(etc) or view.stub.etc . This works for some of my specs. But I've got a couple where it's not working and I don't understand why. The two specs where it's not working test a view, which calls down into a partial, and

问题 Can anyone please shed some light on how to route your sub-folder's .html.erb files?? which is placed like this: view/pages/en/index.html.erb and to route this i am doing following things on route.rb match ':lang/index', :to => 'pages/en#index' and for a link code, I have this on the header <%= link_to "Home", index_path %> The error i am getting is Routing Error uninitialized constant Pages routes: 回答1: AFAIK, There is no way to route to a view.

问题 In my app when I am switching views, after about the 4th time I switch views I get a crash that says: *** -[CALayer retain]: message sent to deallocated instance 0x6c4ba0 I have NSZombieEnabled in Xcode and it points me to this line whenever it switches views: [self.view removeFromSuperview]; Also if I do a backtrace of the (gdb) it gives me this: #0 0x37dd68a0 in ___forwarding___ () #1 0x37d31680 in __forwarding_prep_0___ () #2 0x37d1d026 in CFRetain () #3 0x37d26bb2 in +[__NSArrayI __new::]

问题 Basically for my webapp I'm trying to organise it a bit better. As it at the moment, every time I want to load a page, I have to do it from my controller like so: $this->load->view('subviews/template/headerview'); $this->load->view('subviews/template/menuview'); $this->load->view('The-View-I-Want-To-Load'); $this->load->view('subviews/template/sidebar'); $this->load->view('subviews/template/footerview'); As you can tell it's not really very efficient. So I thought I'd create one 'master' view

问题 I'm developing a web application, and I need something like this: url(r'^$', 'collection.views.home', name='home'), url(r'^$', 'collection.views.main', name='main'), If the user is authenticated, go to main, otherwise go to home. On the home page, differently there will be a sign in a button. But these should be on the same URL pattern. How can I handle it? 回答1: To handle that kind of thing you can use a single view that follows different code paths depending on the request state. That can

问题 So, I have this nice little view that I've made, which basically shows two buttons with some status labels. Nothing too complicated. <?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="fill_parent" android:layout_height="fill_parent" android:gravity="center" android:orientation="vertical"> <LinearLayout android:orientation="horizontal" android:layout_width="wrap_content" android:layout_height="wrap_content">
