This article mainly introduces the Laravel framework implementation of the model layer of the deletion and modification (curd) operation, combined with the example form analysis of the LARAVEL framework model layer for the database to delete and modify the operation of the specific implementation skills, the need for friends can refer to the next

Model prototypes in Suteki.shop are created based on LINQ to SQL, and their dbml files are located in suteki.shop\shop.dbml. And suteki.shop in this file basically, in the way of "partial class" in the Suteki.shop\model folder to create a corresponding class file to extend the SHOP.DBML model class of some methods and property declarations, the following figure:
Label:For the database, in order to ensure the security of data and high availability, often use the master-slave architecture model, for MongoDB is also the case, this article will explain how to build a simple MongoDB master-slave architecture model. In the following example, because there are no multiple servers, experiments were performed on a single server,
After work, I found an easy-to-understand example of a simple factory model while reading the materials. I tried it myself and felt that I was not familiar with this design model,You will immediately know what is going on.
The simple factory mode returns instances of one of several possible classes based on the data provided to it. Generally, the class it returns

? Given the assumption that the same message is used. The above implementation will form a dead loop. The reason is that after the shuttle ESB instance is started. The instance listens to one or more given message queues, assuming that the advertisement side and the Subscriber listen to a queue, forming a dead loop.Here are some examples of how to prepare for your development1, install Microsoft elimination of the interest queue: MSMQFor detailed installation please see:Shuttle ESB (i): Getting

Brief introduction
The concurrency primitives of the go language allow developers to build data pipelines in a way similar to Unix Pipe, which efficiently leverages the benefits of I/O and multicore CPUs.
This article is to talk about some examples of the use of pipelining, pipeline error handling is also the focus of this article.

very beautifully. In fact, I played a trick here to delay the switch statement. Although the Code in the mediaplayer looks neat, the troubles are simply transferred to the mediaplayer caller. For example, in the main program interface:
Public void btnplay_click (Object sender, eventargs E){Switch (cbbmediatype. selectitem. tostring (). tolower ()){Imedia media;Case ("MP3 "):Media = new MP3 ();Break;Case ("WAV "):Media = new WAV ();Break;// Other type
, MindManager's designers probably want to donuts), if you need more examples, you can click on the "online Map Gallery ..." link to download via MindManager's online download channel.In fact, we can find more examples in MindManager, but this is generally not known to beginners. There is a "new" icon in the upper-left corner of the MindManager interface. It is important to note that when using the mouse, do not click the icon directly, but to click the icon to the right of the drop-down button,
create an instance of that class every time you need it, it obviously reduces the execution efficiency of the program, so you often put an instantiation of that class in a static{} , you only need to execute the first call and improve the execution efficiency of the program as follows:Static { try { configuration.configure (configfile); = configuration.buildsessionfactory (); Catch (Exception e) { System.err.println ("%%%% Error Creating sessionfactory%%%%"); E.printstacktrace (
At the invitation of the chat group, I gave a lecture on Bim secondary development in the group at on January 1, October 11.
Since the participants are basically from the design institute and the construction unit, they gave an overview of revit secondary development and explained revit secondary development in a way that non-programmers can understand.This allows industry leaders or owners to understand the general features of revit secondary development and the functions they can implement. t
