Safest way to store and display code blocks in html?

I have a flask backend, and I'd like to do something similar to Reddit or Stackoverflow in terms of styling and displaying code. The code and associated data would be stored in a DB, Flask would fetch it and insert it into the template.

Example

def example():
return "something like this"

How would I safely submit, store, and render code blocks?

Flask App - need help creating route for sql table data

Hi everyone,

I have a Flask app that pulls SQL data into a datatable working away nicely. It's intended for internal use in our warehouse. What I am trying to do is have a link attached to each item name that when clicked, opens a new table with the historical sales listed. I have this working if I manually pass in the name of the product into the SQL stored procedure but how can I get this passing in from clicking on the item in the table.My route looks like this -

\#@app.route('/prev-orders/<itemid>', methods=\['GET'\])

def previous\_orders(itemid):

cursor = cnxn.cursor()

cursor.execute(order\_history)

data = cursor.fetchall() <--this should be fetchone?

return render\_template('previous-orders.html', data=data)

&#x200B;

My href in the <a> tag is href="{url\_for('previous\_orders', itemid=ItemId)}"

Edit - I forgot to show the stored procedure for SQL -

exec Web\_ProductHistory 'APRONS ROLL WHT 2903 (2)' - again, I can manually change the parameter being passed but I need the value passed from clicking on the item name on the table.

Any help would be great and apologies if the question is phrased poorly.

Thank you!

Front-end JS frameworks are an overkill for Django?

I wanted to learn Vue, so I started looking for examples of Vue projects to get some inspiration. However, most of what I find are re-implementing functionality already available in Django.

For example, adding routes is the same as adding urls, the templating system is relatively similar. So I started wondering where is the value of adding thigns like Vue or React to a Django App.

Do you have any examples of projects where front-end frameworks actually achieve something that couldn't have been done directly with Django templates? To mind, I can think only about Wagtail, which uses React (I think) to manage content.

For what I see, unless it is fairly complex user interaction there is no real gain in adding yet another framework. But I may be mistaken. Any examples or ideas to light up the discussion are always appreciated.

Advice on getting started with Channels, ultimately to be deployed to Heroku

Hello experts, I'm about to start a Django project where I will use Channels for the first time. Users will get views "pushed" to them as part of a market research activity (answering questions together as a group while on video chat etc).

I will be hosting on Heroku when it's live. I'm in the process of reading tutorials, walkthroughs etc and I have a couple of questions please.

Context:

* Installing channels is fine - **pip install channels**
* I know I need a backend and have no reason not to go with the standard Redis. But there are so many different ways I'm totally confused what to do:
* The [Channels tutorial](https://channels.readthedocs.io/en/latest/tutorial/part_1.html) recommends a docker install.
* [Redis themselves](https://redis.io/download#installation) use a wget procedure to build from source...
* [This](https://realpython.com/getting-started-with-django-channels/) realpython walkthrough recommends installing **asgi\_redis** and then **brew install redis**.
* [Heroku themselves](https://devcenter.heroku.com/articles/heroku-redis#connecting-in-python) take a different tack with **pip install redis** and **django-redis-cache**

To my questions:

1. Let's assume that I want a vanilla setup, because I'm new that this, and given that I will be deploying to Heroku, which goes through requirements.txt to install all the right packages, is the Heroku path the right way

My Python Youtube channel just hit 20,000 subscribers - buildwithpython

Hey guys,

About a 2 years ago, I started a YouTube channel because I wanted to learn python. Teaching is the best way to learn. Both the channel and I have come a long way.

I wanted to thank the Python community for being so awesome. Thank-you for sticking around.

If someone is curious about the channel - youtube.com/c/buildwithpython

Or you can just search for buildwithpython on YouTube.

Just wanted to share my happiness with the community :)

Building a multiplayer chess game with Channels

Hey guys,

I've been learning django-channels lately and wanted to make a small project to understand how it works better so I thought about building a site where you can create a new game room and play chess with other people.

I've been researching the best way to build and structure my project but I have a few questions.

1. Let's say I have created a GameBoard model that represents the current state of the game, would it be a good idea to send that object over the websockets back and forth everytime the player makes a move, or clicks on a piece (to see possible moves) in order to update the board. Or should I implement some of the game logic inside the js code.
2. How do I go about rendering the game board inside the html, do I need to "redraw" the entire board everytime a change has been made? Could I use django templating here or just javascript to do this without refreshing the page.

I don't have any experience making web-games so please excuse me if anything is not understood.

Thanks in advance for any help.

Made a super basic role-requirement decorator for flask-login

I wanted to add an admin user-type to my flask app, in addition to the basic authorized user that flask-login provides. I didn't want to use flask-user or flask-security, which I understand have role-based authorization, because they require additional database tables. I wanted the bare minimum, where a User's role attribute is just a string. I just wanted the extra decorator, not anything else.

Here's the result. A single file, customizable route decorator for adding a required roll to a view.

How to have my API send data to just my front end?

Hey guys I am making a flask API using flask-restful. At this point anyone can call my endpoints and get data, but since its a user/pw application on the front end, I think building a token system would just be a waste if I just use it for a frontend/mobile in the future.

[D] Examples of good science in deep learning experiment-focused papers

It's been brought up a lot that there are a lot of low-quality "benchmark papers" that get accepted to top conferences based on results even though they have bad science ( [this paper goes into more detail on this](https://arxiv.org/pdf/1807.03341.pdf)). So I was wondering what example papers the community looks up to and what about them makes them good for you, that primarily is based on empirical/experimental results. RL papers encouraged!
