How to show a number labels for a notebook?

Sorry if this is too simple but I've been trying to look for an answer for this and I just cannot find it anywhere.

I'm gonna give a simple tutorial for some scipy stuff on jupyter notebook and I want my students to know which cell of the notebook I'm at. The input/output number of the cell doesn't help since it changes according to the number of cells you've run before.

Thank you for your answers.

Just launched Buzzbomb, my B2B platform built with Django (took 3 months to code!!)

Hey guys,

🎉 I just launched https://buzzbomb.com/ on Product Hunt, you can see it here! https://www.producthunt.com/posts/influencers-by-buzzbomb

So happy to have finally launched after coding for 3 months (although I guess there's more to come). I will be posting about the journey on my YouTube channel (including all the revenue metrics) if you want to follow along.

I'm trying to build 12 Startups in 12 Months for 2021 so yeah - will be an interesting year 😅. Next month I will be doing a daily video on my YouTube channel on the coding progress (sort of like a personal standup diary), but which also be showing the code I write etc. if you're interested!

I built this with Django + Vue.js, Django has my heart and will be using it for all the projects I build!

How to apply not required on model field?

I have a post model that I'm trying to apply not required on image field. Basically, what I'm trying to do is when a user creates a new post, he or she does not need to upload an image. Right now the way it is set up, if image is not uploaded it gives error: "The 'post_image' attribute has no file associated with it" . I tried with blank=True, null=True, but it does not work. What am I missing here? Is there something that I need to do on ModelForm? Any help will be greatly appreciated. Thank you. Here is the code snippet at Pastebin .

Looking for a good naming convention for user-uploaded media files?

When uploading a media file, for example, an image inside ImageField, you can customize the filename by passing a function to the "upload\_to" argument.

Simplified example:

def rename_image(instance, filename):
return "new_name.jpg"

class Profile(Model):
picture = ImageField(upload_to=rename_image)

​

Assuming that you don't care about the original filename, I can see there are a few options to rename the file:

1. Don't rename it and leave the name as the original file -> "cool pic i took on the seawalk.jpg"
2. Use the ID of the instance you are creating (in this case Profile ID) -> "1.jpg"
3. Use a random unique hash -> "h3gdy652gshj372gs72t7.jpg"
4. Use another related field (for example the username) -> "peter\_steve.jpg"

Not sure if there are other options.

* Option 1 could have name collisions or a huge discrepancy between filenames.
* Option 2 is not possible in many cases since Django doesn't allow to get the ID of an instance that doesn't exist yet.
* Option 4 if the user decides to change his username, the image will now have a different username in the filename (not a big deal but what's

Many to many relationship?

Hey. So in the past I have used one to one relationships with Flask SQLAlchemy, but I can't seem to wrap my head around many to many. I have three Tables:

* User
* Product
* Order

I need User to have access to Product, and order

I need product to have access to Order and User

I need Order to have access to User and Product

​

class User(db.Model):
__tablename__ = 'users'
id = db.Column(db.Integer, primary_key=True)
email = db.Column(db.String(255), nullable=False)
password = db.Column(db.String(255), nullable=False)
store_url = db.Column(db.String(200), nullable=True)
activated = db.Column(db.Boolean, default=False, nullable=False)
acc_id = db.Column(db.String(50), nullable=True)

class Product(db.Model):
__tablename__ = 'products'
id = db.Column(db.Integer, primary_key=True)
store_name = db.Column(db.String(255), nullable=False)
item_name = db.Column(db.String(255), nullable=False)

Would you be interested in a Django-allauth prettified template ?

When starting a project I usually spend quite some time making the authentication pages provided my Django-allauth looking pretty.

Would there be an interest to make a public repo with “prettified” templates?
