crud

问题 I am trying to add file upload (filestore) to an existing CRUD page. The examples I've found are all rather dated, and apparently filestore has changed enough where most of what you'll find is obsolete. I did locate this tutorial video, which shows step-by-step how to implement filestore in sufficient detail that a relative novice (me!) was successful. Filestore install begins at 0:34:30 [link]http://www.youtube.com/watch?v=h5dmAnvri1I&list=PL7CBF92AB03A1CA3B&index=9! Thank you, Mark 回答1: I

问题 ASP.NET MVC makes it really easy to create editing templates for simple, flat objects. But managing CRUD for complex objects with several indirections when using something like Fluent NHibernate, is not so obvious. Example To illustrate my question with a simple Invoice manager, Invoice entities have a Project property: public class Invoice { ... Project Project { get; set; } // where Project class has an Id and a Name } ...which is mapped to the Projects table via Fluent NHibernate in my

问题 I'm creating a Django powered website that will have numerous applications (Blog, Shop, Portfolio, etc.) that will be edited by 5 or so people, and I have so-far been designing everything with the Django admin in mind. I have come to realise that this is a very bad way of thinking -as really- the Django admin should really only be for top level administrators, and should be used for exactly that: administrating the website, not contributing to it. I wrote out the feature-set and realised that

问题 Currently I'm trying to figure out what's the easiest way to perform CRUD operations on wiki pages (using PHP). I've built an media wiki extension where it's possible to upload a file and parse its content. Depending on the content it is necessary to either create or update the respective wiki articles. The question is if there are already some nice implementations (or best practices) which I might use or if I have to start from scratch with the wiki api. 回答1: Ok, this was a lot easier than

问题 I tried to implement codes in the book entitled "Learning Laravel 4 Application Development" . A simple use CRUD app as following, Controller $users = User::all(); return View::make('users.index', compact('users')); View <!--an simple table ...--> <div class="pagination"> {{ $users->links() }} </div> And it shows an error: Call to undefined method Illuminate\Database\Eloquent\Collection::links() Could someone give me an hint?. 回答1: You are using pagination, so User::all() won't work because

问题 I have a CRUD Resource defined via Route::resource('User', 'UserController') . Since it is possible to generate CRUD Gates and Policies, is there a way to apply such a Gate / Policy, so that the corresponding gate / policy is applied to a specific route? I think that would be an elegant way, since my polices would match my routes. I'm looking for a method like applyPolicy or something simliar: Route::resource('User', 'UserController')->applyPolicy() Otherwise I would have to add each policy

问题 I am trying to write a generic CRUD trait for Slick 2.0. The trait should a) provide generic methods to read/update/delete entities as well as b) abstract from the database. Following this slick example (database abstraction) and this article (CRUD trait) I came up with the following (shortened) code snippet: trait Profile { val profile: JdbcProfile } trait Crud[T <: AbstractTable[A], A] { this: Profile => import profile.simple._ val qry: TableQuery[T] def countAll()(implicit session: Session
