Enable Server
Start a lightweight Web application server included in the Django framework. Therefore, when developing a Web project using the Django framework, you do not need to configure the server for it, for example, Apache configuration. (PS: the lightweight Web application se
As you know, the multithreading security of Java is implemented based on the lock mechanism, and the performance of lock is often unsatisfactory.The reason is that Monitorenter and Monitorexit, the two bytecode primitives that control multithreading synchronization, are implemented by the JVM relying on operating system mutexes (mutexes).A mutex is a resource-intensive operation that causes a thread to hang and, in a short time, needs to be re-dispatched back to the original thread.In order to o
In the process of planning and designing a website or software, we often hear this discussion: "This function is designed too much" or "we want to be able to handle it more lightly". It seems that light design is a hot topic today, but also in the ascendant Web2.0 of the designer's favorite (see Those in the world everywhere SNS site, whether visual elements or interactive process can be light light). This paper, from the point of view of practice and summarization, puts forward 6 techniques to
1. Create an app, Python manage.py startapp appname
2. Design model, edit the model in the appname/directory
3. Detection of model changes, Python manage.py makemigrations appname
4. Automating database migrations and synchronizing the management database structure, Python manage.py sqlmigrate 0001
5. Create a data table for the newly defined model in the database Python manage.py migrate
Steps to change the model:
Edit the models.py file to change the model.
Run python manage.py mak

_ Init _. py: Let Python treat this directory as a development kit (a group of modules ). This is an empty file. You do not need to modify it.Settings. py: Set or configure the Django

A simple database access layer based on EntityFramework Core, applicable to lightweight database services and lightweight Databases
The code of this access layer is actually from a senior in the garden. I just thought it was good and recorded it.
The access layer needs to install EntityFramework Core through Nuget, but I personally think EF 6 can also be used.
It is best to match databases with SQL Server (

The reason behind the for loop is starting from 2 is because $getparam[0] represents the controller, $GETParam [1] represents the method. These are not parameters, they are all in the $_get, and they are some parameter information.
The following controller name and method name is the first detection of the existence of $getparam, if it exists in the $getparam, if it does not exist then the detection according to the controller nam
