What Is A Framework?

You can avoid unnecessary code repetition with the help of a base template file, which all of your HTML files will inherit from. You can use the CSS language to style the application and make it more appealing using your own design. However, if you’re not a web designer, or if you aren’t familiar with CSS, then you can use the Bootstrap toolkit, which provides easy-to-use components for styling your application. Stop the development server in your other terminal that runs the hello application with CTRL+C. You use the python command line interface with the option -c to execute Python code. Next you import the flask package with import flask; then print the Flask version, which is provided via the flask.__version__ variable. Now you’ll install Python packages and isolate your project code away from the main Python system installation.

But what framework should your developers make use of for web applications? One option is Flask, which is a micro web framework for Python.

Being the grandaddy of Python web frameworks, Zope has grown into a family of frameworks over the years. Zope 2 is both a web framework and a general purpose application server, today it is primarily used by ContentManagementSystems.

All of the Zope frameworks include the ZODB, an object database for Python. There’s another approach to building URLs dynamically in Flask applications. This is basically the building routing approach in reverse order. The easy way of hard-coding routing is what we have seen using `app.route()` and `app.add_url_rule()` methods.

In the preceding code block, you first import the Flask object from the flask package. You then use it to create your Flask application instance with the name app. You pass the special variable __name__ that holds the name of the current Python module. It’s used to tell the instance where it’s located—you need this because Flask sets up some paths behind the scenes. You’ve most likely gotten the sense by now that there are a lot of similarities between these two. It’s increasingly often that they are mentioned in the same breath.

This type of query would provide a list of objects (even if it’s only one object or none at all), so to get the object you want, just call first(). Start with a view that handles onlyGET requests, and respond with the JSON representing all the routes that will be accessible and the methods that can be used to access them. They will ensure that, no matter what machine the code runs on, it always points at the right stuff if that stuff is configured in the running environment.

The user can access the information stored in the session, but cannot modify it unless they have the secret key, so you must never allow anyone to access your secret key. See the Flask documentation for sessions for more information. In the next step, you’ll retrieve the posts you inserted into your database and display them in your application’s homepage.
