I just wanna give a shout-out to my friends in the Django community

I work with a small business and I don’t get to use Django in my work environment (I’m working with PHP) but I come home and practice with Django, building small things. I love the framework. I hope to make it a professional thing sooner than later.

Having to stop Flask server to run other functions.



I'm currently trying to make a simple flask server that gets input from the local frontend, uses the input to get certain data from a CSV, and then send the data back to the frontend. (I'm brand new to python and web development).

The issue that I'm having is this:

When I run the program, it starts the server and I go onto the frontend and post the input to the backend. It then stores the input in a variable.

I then have to manually stop the server by pressing ctrl-c. This then allows the code after it to run. (The function to get data from the CSV).

Do I then have to automatically restart the server to then send the data to the frontend? This just seems too complicated, and I've been told that you can do all this without stopping the server at all in the first place. I heavily get the sense that I'm missing the trick somewhere, however I'm new to this so pls understand :).

Please let me know if the above makes no sense and I'll try to rephrase.

Making Jupyter notebooks more SQL-friendly?

As a data scientist, I spend a lot of time preparing SQL queries, usually in a Jupyter notebook; however, I feel the experience isn't smooth. After a few days of beginning some analysis, my notebook is full of copy-pasted SQL chunks and a weird mix of SQL and pandas.

Sometimes I use the [ipython-sql](https://github.com/catherinedevlin/ipython-sql) extension, allowing me to write simpler code than [pandas.read\_sql](https://pandas.pydata.org/docs/reference/api/pandas.read_sql.html). However, I think some features would come in handy.

Here's my wishlist:

* Facilitate writing large queries
* Choosing plotting backends like matplotlib, plotly, etc.
* Plot computation by the SQL engine

Anything I'm missing? What would it make a smooth SQL experience in Jupyter notebooks for you?

3 models union function mixing up values

so I have this function



`def all(request):`
`movie = List.objects.all()`
`music = MusicList.objects.all()`
`book = BookList.objects.all()`

`a = movie.union(music)`
`allPosts = a.union(book)`

`# allPosts = List.objects.filter(title__search=query)`
`params = {'allPosts' : allPosts}`
`return render(request, 'app/all.html', params)`

All 3 models have same fields

​



`class List(models.Model):`
`title = models.CharField(max_length=65)`
`author = models.ForeignKey('Author',on_delete=models.SET_NULL,null=True)`
`genre = models.ManyToManyField('Genre')`
`posted = models.DateTimeField(auto_now_add=True)`
`content = RichTextField(null=True,default=' ')`
`type = models.CharField(max_length=10,default="Movie")`



`class BookList(models.Model):`
`title = models.CharField(max_length=65)`
`author = models.ForeignKey('Author',on_delete=models.SET_NULL,null=True)`
`genre = models.ManyToManyField('BookGenre')`
`posted = models.DateTimeField(auto_now_add=True)`
`content = RichTextField(null=True,default=' ')`
`type = models.CharField(max_length=10,default="book")`

​

and so on

​

in my template



`<div class="thumb">{{allPosts}}</div>`
`{% for lola in allPosts %}`
`<div class="elements">`
`<div class="thumb">`
`<img src="{% static 'app/images/movie-poster.jpg' %}" width="100px" />`
`</div>`
`<div class="Title">`
`{% comment %} <a href="{{lola.id}}/"><h4 class="tit">{{lola.title}}</h4></a> {% endcomment %}`
`<a href="{{lola.id}}/"><h4 class="tit">{{lola.title}}</h4></a>`
`</div>`
`<div class="Author">`
`<small>Author : {{lola.author}}<span>{{lola.posted}}</span></small>`

How do I integrate Django rest with ckeditor?

Does anybody know a good tutorial that explains how to integrate Django rest Framework with ckeditor (or any similar editor). I am making a RESTfull API to be consumed with react. I would like to edit blog posts on Django Admin then use the endpoints in react. I have been googling for the same but I can not find a tutorial. Here's the project if you wanna look around. Thanks.

Machine Learning from Scratch with Python

Hey everyone!

I've seen a growing number of people looking for resources on how to implement Machine Learning algos from scratch to better understand how they work (rather than just applying e.g. sklearn).

This free **Machine Learning from Scratch Course** on YouTube takes you through writing 10 algorithms from scratch with nothing but Python and NumPy! The algorithms are:

1. K-Nearest Neighbors
2. Linear Regression
3. Logistic Regression
4. Decision Trees
5. Random Forest
6. Naive Bayes
7. PCA
8. Perceptron
9. SVM
10. K-Means

Hopefully some of my Python + ML friends will find this helpful! :)

Tried using the codes below but it is not the kind i wanted. I wanted 4 subplots with the xaxis as 'salary' or is there other way to show it?

Argument parsing/validation for flask?

Is there a way with flask to create some sort of argument serializer deserializer?

I really like in django how you can specify a serializier that take a requests urlparams/body and tells you which fields are correct, which are required and what format they need to be in.

I was hoping there might be an equivalent for endpoints that don't directly use a sqlalchemy/marshmallow serializer

thanks for any help!

CI/CD Django How to make this work: push to GitHub > run GitHub action (tests) > auto deploy app if tests passed?

Hello guys,

I'm new in CI/CD and not-so-experienced in Docker. Right now I have my Django project deployed on DigitalOcean droplet and every time new code is pushed to GitHub, after GitHub action that runs tests automatically, I need to deploy the project manually.

I'm trying to figure out how to make this flow automatic.

This is what I want:

1. push to master (manually)
2. run tests on master (auto)
3. automatically deploy app (auto) if tests passed

I'm considering DigitalOcean Apps platform but the code would be deployed even before the tests passed.

I'm also considering Dockerizing the app but I'm not sure how that would help.

&#x200B;

Can you give me some advice? How would you do that?

&#x200B;

Thanks

Deployment - After setting up Gunicorn, Nginx and turn DEBUG = False, how do you update your code?

Is this done through your VPS service (digitalocean, vultr, aws, etc.) ? I am still in my local environment and I have a self-signed HTTPS cert set up so I can "see" what my project will look like without running Django's built-in server. Everything looks good but I wanted to change a couple of things (css, html in the templates, and some of my backend logic in the views.py) but none of my changes have taken effect.

I have:

cleared my browsers cache, restarted Gunicorn and Nginx service, none of it worked. It's almost as if Gunicorn and Nginx have a snapshot of my web app and cannot see any updates that I make.

Any help would be greatly appreciated.
