Creating a rest api with many to many relationships

As the title says I'm creating an API to map employees to shifts, I've got /employees and /shifts, but I'm a little confused about creating an endpoint to map the two? I was going to create another endpoint /patterns, and then pass an employee id and shift id and parameters to create a new mapping, does this sound correct? Also do I need to create a new model or serializer for this endpoint?

thanks

My university is thinking of teaching the engineering students python instead of matlab - How to help convince them?

Hey all

As the title suggests, the teaching committee at my university are thinking of moving from teaching undergrad engineering students python instead of matlab.

Since they've asked for some student input, can anyone think of any decent arguments to try to make the move?

biggest reason presented for keeping matlab is that matrix manipulations are easy (if you've ever tried to do FEM stuff in numpy it just makes you sad).

PRAW 4.5.0 Released

Notable additions:

* Complete API support for the new modmail system (huge shout out to [Levi Roth](https://github.com/leviroth) for the implementation)
* inbox stream
* Ability to introduce pauses into streams (thanks /u/elnuno)

Please see the 4.5.0 change log entries here: https://praw.readthedocs.io/en/latest/package_info/change_log.html

### PRAW 5

The next release, sans any necessary bug fixes, will be PRAW5 in order to resolve all the deprecations up to this point in the PRAW4 versions. Those items are already enumerated in the previously linked change log. To make use of these changes now, install the development version of PRAW via:

pip install --upgrade https://github.com/praw-dev/praw/archive/master.zip

Thanks again to everyone who has contributed to PRAW via code, documentation, or by simply helping to answer other people's questions. PRAW wouldn't be what it is today without your help.

Science Flask: a web-app template for online scientific research tools, built with Python Flask

Here's [Science Flask](https://github.com/danielhomola/science_flask), a template project for scientic web-apps. If you're a scientist planning to put your research tool online, then hopefully it will save you weeks of development time. I definitely wish I had something like this when I started [CorrMapper](https://www.medbio.imperial.ac.uk/corrmapper/).

Why did Flask run past CherryPy?

I've been wondering this off and on for awhile. I've been a user of
Python before Flask existed and CherryPy served me well then. And it
still does now. I simply don't understand what motivated the creation
of Flask when CherryPy already existed. And I certainly dont
understand why anyone who did a point-for-point comparision of
frameworks before choosing one would choose Flask, save for popularity
of the author.

The first thing I notice about Flask is manual routing whereas
CherryPy has automatic routing by default. That seems like a step
backward not forward.

The rest of my observations about the 2 microframeworks I will post as
a reply
to
[Eric Larsen's post on the subject](http://ionrock.org/2014/12/19/flask_vs_cherrypy.html).

I agree that CherryPy is not popular. I dont know what rough edges you
are taking about. It works fine for me.

> The best thing I can say about Flask is the community of projects.

Seconded. There are a lot of downloadable flask apps and plugins.

> Flask-Admin is extremely helpful along side Flask-SQLAlchemy.

Yes, I really like an automatic admin interface. That is the one thing
I miss from Django. And what I disliked about Django (`settings.py`)
is solved by something called `importd` (but I cant find a link to
it). But what I see as unsolveable by Django is that the ORM is not SQLAlchemy and I refuse to have things like "Stale MySQL handle" errors... anyway, back to the CherryPy/Flask topic of this post.

Hmm, being able to mount applications is a big thing and if Flask
forces you through a tube to do it, then that sounds like an OK
thing.

How do I make my package available to do 'conda install XXXX'? I already got 'conda install -c jos_pol pandas-profiling' working

Hi all,

Does anybody know how to register a package in the main Anaconda channels? I already got

> conda install -c jos_pol pandas-profiling

working. Ideally, i would like to have instead

> conda install pandas-profiling

Just like with pip you just have

>pip install pandas-profiling

Is that even possible or is it restricted to a manually curated list by the Anaconda folks?

Why use RESTfull API?

So far I just worked with flask rendering all websites itself. Example: http://flask.pocoo.org/
Yesterday I heard about RESTfull API. Example: https://blog.miguelgrinberg.com/post/designing-a-restful-api-with-python-and-flask
What is the advantage of separating the front end (VueJS, AngularJS, ...) and the backend (flask, returning JSON)? Unfortunately, I didn't understand the reason.

Google assistant on MacOS

I got the google assistant to launch on macOS with one touch

I had to modify the python code samples slightly to exit when a conversation is complete. Used automator to create an app out of shell script that activates virtualenv and runs the code.
Finally, I am using better touch tool to launch the app with a corner-tap on the trackpad.

Best part is that it recognizes my accent perfectly :)

[New to Django & Python] Is the two scoops book good for learning Django as a beginner who doesn't have experience with frameworks?

I o a do-able tutorial from the djangobook.com site - title, but it's outdated and i already have Django 1.11 installed. It's like solving a puzzle now instead of following the tutorial/guide. I have to search on the web for the out-dated answers and i am thinking about reading the two scoops book but will it be to hard, isn't it just a reference book which expects you to be experienced already with Django?

Problems using Flask and AngularJS together

Im making a simple web applciation right now using Flask and AngularJS. However, since adding some AngularJS code to my web page, im having problems running my website locally. I just keep getting errors saying things in my Angular code are not defined [like this](http://imgur.com/a/zvkRH) when they run perfectly when i just double click on the .html file without starting up my flask app.

My code is [here if](https://pastebin.com/e0aGnBCN) for you to take a look at if needed.

Is there something I should be doing to make them work together or are they not compatible or something?
