For parts where Flask depends on external libraries, we document the most important right here and provide links to the canonical documentation. The flask object implements a WSGI application and acts as the central object. It is passed the name of the module or package of the application.

Once it is created it will act as a central registry for the view functions, the URL rules, template configuration and much more. The idea of the first parameter is to give Flask an idea of what belongs to your application.

This name is used to find resources on the filesystem, can be used by extensions to improve debugging information and a lot more. Why is that? However it will make debugging more painful.

Certain extensions can make assumptions based on the import name of your application. If the import name is not properly set up, that debugging information is lost. For example it would only pick up SQL queries in yourapplication. New in version 1. Subdomain matching needs to be enabled manually now. New in version 0. Defaults to 'static'. Defaults to None. Defaults to False. Defaults to 'templates' folder in the root path of the application.

By default the folder 'instance' next to the package or module is assumed to be the instance path. In certain situations this cannot be achieved for instance if the package is a Python 3 namespace package and needs to be manually defined. Register a custom template filter. Register a custom template global function.

Register a custom template test.

Connects a URL rule. Works exactly like the route decorator. Changed in version 0. Flask itself assumes the name of the view function as endpoint.

A change to Werkzeug is handling of method options. Starting with Flask 0. As of Flask 0. A dictionary with lists of functions that should be called after each request.

An application context is automatically pushed by RequestContext. Use this to manually create a context outside of these situations.

See The Application Context.JSON is a lightweight data format which is widely used across web applications for interchanging data across and within web applications.

From the official docs. It is easy for humans to read and write. It is easy for machines to parse and generate. These properties make JSON an ideal data-interchange language. This tutorial assumes the user to have the basic knowledge of Python programming language and Flask framework. Once you have Flask and Python installed in your system, create a file called app. Try running the app. And whenever we need to transfer the data to client side, we simply convert the data to JSON and send it to the client side.

Import the employee. Inside the getEmployeeList method in app. As seen in the above code, we have created 5 instances of the employee class and inserted it into employeeList. Install package names for random name generator. Define a method called toJSON in the employee. Import JSON in the app. In the above section we saw how to convert a class instance or object list to JSON data.

Here I have dealt with two general cases where we need to convert the python class objects and result sets retrieved from database to JSON data. Do have a look at other Python programming tutorials on CodeHandbook.

I blog about web development related tutorials and articles in my free time. See author's posts. I tried this way, the output does come, but not as expected. This is how the JSON is outputted:. Do have a look and let me know if solves your issues. I tried your suggestion mentioned in the above URL.

But, the problem is that it works only for a list defined in the code, like you did. Your explanation assumes you know the fields in the JSON being read in.
