问题 Is there a CRUD generator utility in Java like Scaffolding in Rails? Can be in any framework or even plain servlets. Must generate controllers + views in jsp, not just DAO code... 回答1: Spring Roo seems to be exactly what you're looking for: CRUD code generation, spits out pure Java code that can be made tun run entirely independant from the framework. 回答2: Grails has scaffolding. 回答3: See the Telosys Tools Eclipse plugin at http://www.telosys.org/ The plugin connects to the database,

问题 I have developed a handful of appengine apps which I finally have realized are examples of CRUD on top of CRUD. That is, I, the adminstrator, offer my app to users so they can either use the app (say a note taker app) themselves or can invite other acquaintances, typically non-users, to exercise the ultimate app (for example, ParticiPoll, a participative questionnaire which uses the google appengine datastore and no SQL). My only and quite young grandson has asked me to produce a screencast

问题 Think about a simple Rails scaffold application with a "new" action containing a form to add records to a database with a "save" button. After the "create" action the controller redirects to the "show" action, where the user can use the "edit" link to edit the just inserted record. So far, so simple. But if the user instead uses the browser's back button after creating a record to get back to the "new" action, the browser shows the form with the values the user just has entered. Now he

问题 As it currently stands, this question is not a good fit for our Q&A format. We expect answers to be supported by facts, references, or expertise, but this question will likely solicit debate, arguments, polling, or extended discussion.

I need a simple php library which can be used to easily pass rules and field names to, and then validation could be easily performed.

问题 So here's my code sap.ui.getCore().getModel("myModel").update("/ZSystemNameSet(mandt='001')", data, null, function(datay, responsey){ sap.ui.getCore().getModel().refresh(); MessageToast.show("It worked...!! Data: "+datay+"Response: "+responsey); }, function(datax,responsex){ MessageToast.show("Sorry! Data: "+datax+"Response: "+responsex); }); Also how do I add the header attributes to the update() call? 回答1: Obviously your service uses optimistic locking and expects an If-Match header,

问题 I am still a learner of Rails, and am making a simulation game of Google Adwords for training usage. Inside the game (I may only explain the related part of this question), I have three models, Adgroup (called KeywordAdgroup in my code), Keyword, AdgroupKeyword , and also a Game model that has a game_id in it. The relationship of the three models is a has_many through: assciation, which Adgroup has many Keywords through AdgroupKeyword, and Keyword has many Adgroups through AdgroupKeyword. Now

问题 Hi i have a most common situation of inserting a client order into my SQL database. I have created an order header and order detail tables in the db and i am trying to insert a single header record and multiple detail lines corresponding to that header record (the PK and FK constraint is the headerID). Currently, i insert my header record, then query the db for last created headerID and use that ID to insert my detail lines by looping through grid for example. I know this is a stupid way for

问题 Okay, this is really weird. I made a simple database with a single table, Customer, which has a single column, Name. From the database I auto-generated an ADO.NET Entity Data Model, and I'm trying to add a new Customer to it like so: using System; using System.Collections.Generic; using System.Linq; using System.Text; namespace Test { class Program { static void Main() { Database1Entities db = new Database1Entities(); Customer c = new Customer(); c.Name = "Harry"; db.AddToCustomer(c); db
