Detailed Flask Web Development Series

Hey guys,

I’ve been working on building a really detailed course around the Flask framework to get many beginners started with web development with Python.

Course Page: https://www.thecodewolf.com/courses/python-flask-web-development/

Here are the first few videos of the series, I’ve also have written tutorials with the videos as well:

* Overview & Installation
* [Video](https://youtu.be/Ty2qAlDsAxc)
* [Blog Post](https://www.thecodewolf.com/introduction-to-python-flask-web-development-overview-of-flask/)
* Hello World & Flask Application Structure
* [Video](https://youtu.be/OrTWfZpv0i0)
* [Blog Post](https://www.thecodewolf.com/python-flask-web-development-hello-world-flask-application-structure/)
* Flask Templates, Jinja2 Tutorial, Bootstrap Integration, and Custom Error Pages
* [Video](https://youtu.be/0M74EGmqWIY)
* [Blog Post](https://www.thecodewolf.com/python-flask-web-development-flask-templates-and-flask-bootstrap-integration/)

The next few videos and guides will be coming out in the next few days/weeks, and I’ll be releasing new content on a regular basis.

**My goal is to create the best foundational web development course with the Flask framework to get as many people started with Flask as a stepping stone in web development with Python.**

If you guys enjoy the content, I will also be working on a detailed series like this with Django as well.

Here are some of the following videos that will be coming up with the series:

* Web Forms with Flask
* Database Integrations with Flask

Then I will be working on content that will actually have you build a complete blog application with users, blog posts, and all sorts of other really cool stuff.

With the current content so far, I would love to hear some feedback as well.

Why does "localhost" not work?

Hi, when I try to serve flask on localhost, flask returns 404 errors. It works on other local IP addresses but I need to do it in local host otherwise I can't test square's API.

Django User's Sessions

So I don't have a DB full of users but have a third party company that contains all my customer data in a DB like users' login credentials. If I am using an API to query the user's data what would be the best practice for creating a users session. like 'django.contrib.sessions' does with the creation of users.
As of now, I can create new users using a form that salts and hashes password, POSTing them to the Third Party companies DB using their API but I don't know how to create a session for the user after I authenticate them.

The API has an SDK for this but it's in PHP thinking everyone would use WordPress. but I won't go that route.

URL Confusion

I am following the django tutorial of thenewboston on Youtube. In tutorial number 12 he goes into creating a URL. I understand what the outcome is I just don't understand how it works or how I would write it myself. Here are the URL patterns.

urlpatterns = [
#/music/
url(r'^$', views.index, name='index'),

#/music/2
#This just blew my freaking mind
url(r'^(?P<album_id>[0-9]+)/$', views.detail, name="detail"),
]
If someone could help explain to me how the second URL works or point me towards an article that would explain it I would be very appreciative.

Is there a way of inputing data into an excel spreadsheet from python?

I am trying to create a program for my school which would allows users to input the books they read, author, date finished etc and then have it stored into a personal spreadsheet. As someone who has little experience doing python how doable is this task? Manu Thanks.

Do all the databases work the same in django?

I think this is a stupid question but i have to ask. I'm a total noob and just started working on django. It keeps scaring by saying over and over again that we should use other databases for larger projects.

Honestly, i have no clue what this means. Moreover i don't have any experience with databases. I started learning python 3 months ago and now i'm thinking i should try django.

What i want to know is if the databases work the same in django? Like will sqlite3 and postgresql work the same or will i have to learn something before doing it? And should i learn databases before learning django or not? IT would help me alot if anyone could clear these things up for me.

Security best practices for Javascript generated field.

I'm using flask_wtf FlaskForm. I would like to sanitize string user input for a JavaScript generated form field. Now there are plenty of external libraries to do this, but I was hoping to find a way within the existing libraries. Any ideas?

Linking results to a notebook

In my work, I do a lot of 'misc' data analysis..and I often am in a situation where I send out results, then a month later, someone asks me to rerun or change something etc... what bugs me is not having to figure out which notebook produced a given results file. has anyone thought of a good system for this? I have thought of including the notebook name as part of the results filename..or maybe somehow including the notebook name in header data depending on the file type. I'd love to hear some recommendations.

Code Review request

Would anyone be kind enough to review my project.

It's...rather large and most of it is in spanish (well, spanglish). Do have a readme that I think covers most of it.
