Blog tutorial in Django 1.10

Hello friends! Happy New Year!

I am new to Django and I am seeking your support. I'm trying to build a pretty complex website with a blog section. I've tried numerous tutorials on YouTube and the documentation and I've ended up frustrated because either the tutorial doesn't really cover everything or I'm running into compatibility issues (Django 1.9 vs Django 1.10) which I couldn't figure out. These two do not really cut it:

https://www.youtube.com/watch?v=yfgsklK_yFo&list=PLEsfXFp6DpzQFqfCur9CJ4QnKQTVXUsRy

Could someone please point me to a full in depth Django 1.10 tutorial or some kind of template? I've pretty good at the Front End and I just want to get my first webapp off the ground.

Much appreciated

URL not appearing in DRF router!

I have all these router url's set up, but when I add search it doesn't work!
router.register(r'search', search_api.SearchViewSet, base_name='search-api')

i've narrowed it down to when i swap out where the view goes (search_api.SearchViewSet), then it shows up on the django 404 page.... I've tried many combinations of views and nothing makes it work! Why could this be. For example, my current view is :

class SearchViewSet(viewsets.ViewSet):
queryset = Data.objects.all()
renderer_classes = (JSONRenderer, )
def get(self, request, format=None):
print('test')
return Response({'test': 1})

Django or flask?

I am completely inexperienced these libraries. I wanted to see it it'd be feasible to build a site that would display some matplotlib graphs and pandas dataframes. Ideally, these dataframes could be filtered or sorted and exported. The underlying raw data would be refreshed every 30 minutes. Someone could visit and see overall performance and then customize their view.

Another big use case for me would be to allow people to update some "custom" dimension tables and to let me know when certain dimensions are expired or recycled. Right now this is done through csv files being overwritten on an sftp site. It'd be nice to have a front end.

My workflow is centered around using a few libraries to gather external data from SFTP sites, shared folders, and even web sites with selenium. I then read this data with pandas, do my formatting and cleaning, etc, and then I use psycopg2 COPY command to send the data to Postgres. Ultimately, his external data (all different formats and sources) comes together into internal reports.

Some of the data is used for reporting which is sent out through emails (attachments and to_html with pandas to display a table), tableau, and to various shared folders and sftp sites. I'd like to test having some of this on a website instead.

I made a small script for looking up word definitions

I've been reading a lot of old texts in school lately which meant I had to keep looking up old words, I noticed that the results almost always showed up in the first page of a google search and decided to try and automate the process.

The script use requests and beautiful soup to send a http search request to google, and then parse through the resulting html fetching any link which domain has a section in config.ini with a css selector for the desired content (the definition of the words).

The script then loops over all the links, extracting the content defined by the css selector in config.ini and displays it in the command line.

I don't know if this is that interesting to this sub, but I thinks is kind of cool and makes my life easier, so I decided to share it in case someone is in the same boat.

py3redirect 1.1 (Chrome extension) - automatically redirects to Python 3 documentation when Python 2 docs page is requested

/u/yaph has posted a link to this Chrome extension some time ago. I am an author of this and recently updated the py3redirect to 1.1, which brings cache (so the extension can redirect immediately if it already knows py3 doc exists for given page) and a button for temporarily disabling redirecting. This version should also fixes the problem with back button - which caused the browser to reload the page (i.e. back to py2 docs, which were immediately redirected to py3), instead of actually going back.

I saw that some people appreciated this however simple work, so I hope you'll enjoy some improvements I made. If you have any other suggestions, that will be appreciated by me. :)

Year of Programming Challenge!

Hello all, there was a post over at r/learnprogramming, it was a thread about people wanting to code everyday for this year. the community outgrew the groupme chat, and grew into a slack channel where we are sitting at 300+ members, and have 60 people forked the github repository. I thought it was a super cool idea and wanted to share it with people over here who wanted to sharpen their python programming skills!

A github organization was created where challenges can be posted and people can submit pull-requests and get their work merged with the organizations master repository. this is amazing as it will help keep our skills sharp, and start to build a github reputation thatll look good to recruiters.

Trying to make my own version of django-admin startproject. Have I created a monster?

I'm currently learning Django, specifically how to create a new project. I was taught to use the command
django-admin startproject {project name}
in bash and then modify some of the files it created. I thought that modifying the same files in the same way every time I made a new Django project was inefficient, so I wrote a shell script that would create the files for me, already modified to how they needed to be.

It seemed like a good idea at the time, but now I'm getting a whole bunch of errors I don't understand. Have I created a monster I can no longer control? Any help is appreciated.

Here is my shell script:
