Months ago, I was planning to take part in the #RailGirls event in Sofia, and I was even a partner in the event. Anyway, as it was postponed up to somewhere in the future, I have decided to go through the DjangoGirls tutorial and to record it. To be honest, I was expecting that the tutorial is “a walk in the park”, but somehow it was a bit more advanced, including JavaScript, Django, OOP Python, SqlLite3, command prompt techniques for adding data to a database and etc.
Was it good? I don’t know, it took me about 3 hours to record it and another 6 to edit it and upload it to YouTube in its final form. Now, when I think about it, I should have read the tutorial before stepping into it. Anyway, this way I have shown that even seasoned developers make rookie mistakes, when they come a bit unprepared into some kind of a project, that they are not currently working on. Thus, all the errors are staying as they were. Plus, I really do not have the desire to edit them out 🙂
Anyway, the whole code is as usually in my GitHub repo here – https://github.com/Vitosh/Python_personal/tree/master/YouTube/002_DjangoGirls.
The core of the project are the following 5 files:
