__name__ == '__main__': manager.run() Extensions designed for Flask are exposed in the flask. ext namespace. Flask-Script exports a class named Manager from flask. ext. script. The method for initializing this extension is the same as that for many other extensions: the initialization of the main class instance is implemented by passing the application instance as a parameter to the constructor. The created object is suitable for each extension. In this example, the server is started to route

initialization of the main class instance is accomplished by passing the application instance as a parameter to the constructor. The objects created are appropriate for each extension. In this example, the server starts routing through Manager.run (), and the command line is parsed here. Recommendation: If you have cloned apps on GitHub, you can now run git checkout 2c to switch to this version of the app.Because of these changes, the application obtains a basic set of command-line options. Run

development of the use of general code changes will be automatically restarted, convenient debugging and development, but due to performance issues, it is recommended only for testing, do not use in the production environment.$python manage.py runserver # 当提示端口被占用的时候，可以用其它端口：$python manage.py runserver 8001$

Objective Traditional Web development methods often need to write tedious repetitive code, not only the page performance and logic implementation of the code mixed together, and code writing efficiency is not high. For developers, the choice of a powerful and simple development framework to assist in the implementation of complex coding work, will be a great help to improve the efficiency of development. Fortunately, such a development framework is not uncommon, and all that needs to be done is

djangodjango.get_version() Create a django Project django-admin.py startproject mysite At this time, some directories and files are automatically generated, and the manage. py at the outermost layer is like a running entry. Through the command line call, you can complete some common functions, such: Running django's built-in web server: python manage.py runserver http://127.0.0.1:8080 Common synchronizatio

booklist(request): list = Book.objects.all() return render_to_response('booklist.html',{'books':list}) 8. modify the content of d: \ mysite \ url. py. The result is: urlpatterns = patterns('', ('^hello/$','mysite.views.hello'), ('^books/$','mysite.books.views.booklist'),) 9. create a new sub-directory templates under the D: \ mysite directory as the Directory for storing the template. Create a new template file booklist.html with the following content {% for book in books %}

step: Configure the URL.Now, if you run again: Python manage.py runserver, you'll also see the Django Welcome page without seeing the Hello World display page we just wrote. That's because our MySite project also knows nothing about the Hello view. We need to explicitly tell it and activate this view through a URL that is described in detail. To bind the view functions and URLs, we use urlconf, the urls.py

Many beginners ask how Python and Django are installed, so here's a quick introduction to the two software installation steps under Windows 2003.First, download and install PythonPython official: http://www.python.org/ftp/python/We have chosen Python 2.7.2 here. Although the latest version is Python 3.2.2, Django does

configuration file, and the templates directory is the HTML file that is the T in MTV. Manage.py is a Django project management file.3. Create an appYou can include multiple apps in each Django project, like sub-systems, sub-modules, features, and so on, in a large project, independent of each other, but also associated.All apps share project resources.Enter the command in the terminal terminal below Pycharm:　　Python manage.py Startapp CMDBThis creat

process. Developers can simply enter the project directory at the command prompt, type the command manage.py runserver, start the Web server to test the newly created project, and if it starts without errors, you will see a message like this: "Development server is Running at Http://127.0.0.1:8000/"indicates that the current project is already accessible via the 8000 port on this machine. Open the above address via the browser, and the initial page o
