An example project and a basic guide showing how to run Django/Celery on Heroku. Basic requirements First of all, let's actually set up a typical Django project for this. We would need virtualenvwrapper for that. One could use any other particular method. I prefer this one. $ cd dev $ mkvirtualenv dch ( dch ) $ pip install django ( dch ) $ django-admin startproject djheroku ( dch ) $ cd djheroku #…
One comes to a task that has to do with counting items in a database. We will describe the right approach here. Despite being so obvious I did not find much of the docs for junior developers to watch and learn. Here is a sample task and solution: Let's assume we have a model like so: class Cycle (db.Model): id = db.Column(db.Integer, primary_key= True ) object_id = db.Column(db.String, nullable=…
Despite using console most of the time I have a preference to edit PostgreSQL databases through UI. Especially when it comes to remote side. Usually one can access this through $ psql command. However this tends to writing raw SQL queries and a lot of typing in overall. Here is a way to do it with UI. First one needs to make a tunnel.Command is fairly simple: ssh - fNg - L 5555 : localhost : 5432…
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…
Found a new pattern to use recently that is called Promise. I really like the way ES6/7 brings new thinking patterns into life nowdays. Here is Promise used instead of old pattern. It was to give JS method a callback function. This splitting code and making a lot of possibilities for error to come out in this place. One would write old times according to MDN : function greeting ( name ) { alert (…

Tmux is a handy terminal manager that allows you to switch between terminal sessions easily. Without losing history or windows upon ssh disconnects or similar. It is like screen , just better. (First of all because of using client-server based technology... ) Here is my minimal keyboard shortcuts guide that allows you to start using Tmux in a blink of an eye. Endless advanced commands and hotkey…
This is a simple guide on installing a must have SQL database engine for web development. It is often used at the beginning of the journey and I did not find a good guide for it. That made me make myself one and share with others. Hope somebody would benefit from it. First we need to setup the MySQL community edition (latest or not depending on your requirements). It's possible to download it…

Task is to migrate all the page content (that is a CMS TextPlugin) into an interlinked pages setup. Like we have text <p>blah blah </p><a href="/page/url">Text</a><p> some other text</p> And I need to change…

Like so: text = "<h1>Test text tag</h1>" soup = BeautifulSoup(text, "html5" ) text = soup . renderContents() print text It renders those contents with a result wrapped into the <html>, <head> and <body> tags. So print output looks like so: '<html><head></head><body><h1>Test text…

Sometimes you need to get out of standard behaviour of your Django admin. It means expanding its functionality with custom things. In our case we have a model that we want to add a custom html element. Button that must load something via AJAX from another place to be exact.

The idea is to have it all stored to Django's CharField type of data and have a preselected set of fields. We have a model: # models.py class Entry (models.Model): SET_OF_CHOICES = ( ( 'choice1' , 'choice1' ), ( 'choice2' , 'choice2'…
