I have gotten to setting UP a Flask environment for a project recently. Was completely puzzled by how to run this. I have used to running Django project with python manage.py script. This means pointing out a PyCharm interpreter into a certain point of entry, that is also a .py file also. In flask way of starting things there is another approach however. Here it is in Flask Docs. It states to set a variable FLASK_APP and then run a flask run command. This will confuse running a python script way of a project being run. Thus to fix this one needs to set a path to flask binary file. It usually is within a virtual environment binary directory, place where your python interpreter resides. So to set debugging one needs to set path to script binary one needs: Script: /path/to/env/bin/flask Script parameters: run   Environment variable  FLASK_APP=app.py Environment variable FLASK_DEBUG=True Set working directory back to your app path (It changes automatically according t...

There are several ways of debugging Django. I'll try to cover most common and tell what I know/use time to time. This article may become useful to Django newbies and is not intended to be "the only truth". It may help you know in general about debugging techniques commonly used in Python/Django projects that author is aware of. Let's get started. There are several methods to discuss here. 1. Print out into console. It may become handy while working with critical bugs that only appear in production for e.g. and are not traceable at development environment... The only way here to run your project manually and do debug in production. Those requirements are so rare that I only use standart (builtin) tools. There is a thing called PDB (Python Debugger). That comes in a standart set of usual python distribution. So it will be available to you at almost any environment where you have console access to your project. Here is an official documentation for pdb module ....

I'm a fan of IDE's. Also I'm a fan of GUI's. I also use console where needed, but why waist time typing commands when you can just point and click. I've been using Eclipse + PyDev for almost a year and recently switched to PyCharm. Why I prefer PyCharm: - Template Debugging. (you can set a normal breakpoints in templates) - Easy Virtualenv connection. (Set an interpreter from your virtualenv and you're ready to roll) - Has excellent set of most common CVS integrations (Git, SVN, Redmine, etc...) - Has looots of tiny tasty things for coding and proper code highlighting over JS and HTML out of the box) - Has proper and shiny themes out of the box. So I'm a blind minded blond, it seems now. But design of this IDE is really attractive IMHO :) - OH and it's quite quick and has ALL the functions I need. Here is a brief instruction to setup PyCharm IDE to work with my typical Django project. 1.  First thing you need is a PyCharm installation. Y...
