Change the Jupyter Notebook font to Comic Sans

I know this might not be the place to ask this question, but I am a TA and I want to annoy my students. I found this guy [jupyter themes](https://github.com/dunovank/jupyter-themes) who changes the theme for the notebook, but to my chagrin, the themes available do not have comic sans. Would like to hear from you guys soon. Thank you!

How do I use/ access a foreign key in views in Django?

I am making a programing etymology site in Django. It will have the etymology/history of programing terms. or

For example the term LET (in ECMA6):
> Let is a mathematical statement that was adopted by early programming languages like Scheme and Basic.

I am not clear on how to write views.

For instance, I want to return the term let and the text of the let terms. Let is in the Term table and text is in the Etymology table.

**EXAMPLE**

Here is what I would like to see returned for term_name=Let.

LET:

Let is a mathematical statement that was adopted by early programming languages like Scheme and Basic. Variables are considered low level entities not suitable for higher levels of abstraction, thus the desire of many language designers to introduce similar but more powerful concepts like in Clojure, F#, Scala, where let might mean a value, or a variable that can be assigned....



**MODELS**

Here are my models.

class Term(models.Model):
term_name=models.CharField(max_length=150)
term_type=models.CharField(max_length=150) #type of command
term_pub_date=models.DateTimeField('Term Pub Date')

def __str__(self):
return self.term_name

class Etymology(models.Model):
term = models.ForeignKey(Term, on_delete=models.CASCADE)
etymology_text=models.TextField()
classification=models.CharField(max_length=150) #prog or tool reference
etymology_votes = models.IntegerField(default=0)
# rating=
# user=
etymology_pub_date=models.DateTimeField('Ety date published')

def __str__(self):
return self.etymology_text[:50] + "..."


class Comment(models.Model):
etymology = models.ForeignKey(Etymology, on_delete=models.CASCADE)
comment_text= models.TextField()
comment_votes = models.IntegerField(default=0)
#rating=
#user=
comment_pub_date=models.DateTimeField('com pub date')

def __str__(self):
return self.comment_text[:50] + "..."

How do I write a view which accesses two tables at once. How would I write the view to return what I want to see from my models?

FYI:
Using Django 2.02 and Python 3.6. Also, I not highly experienced so simple


Citation:

JavaScript?, W. (2018). Why was the name 'let' chosen for block-scoped variable declarations in JavaScript?.

[AF] Factoryboy and Foreign Keys

I'm using factoryboy to build factories (for testing) but I'm not sure what to do with the foreign keys. I have a scenario similar to this (using flask-sqlalchemy):

class User(db.Model):
id = db.Column(db.Integer, primary_key = True)
posts = db.relationship('Post', backref = 'author')

class Post(db.Model):
id = db.Column(db.Integer, primary_key = True)
user_id = db.Column(db.Integer, db.ForeignKey('user.id'))

Right now, I have implemented this:

class BaseFactory(SQLAlchemyModelFactory):
class Meta:
abstract = True
sqlalchemy_session = db.session

class UserFactory(BaseFactory):
id = Sequence (lambda n: n)
posts = SubFactory(PostFactory)
class Meta:
model = User

class PostFactory(BaseFactory):
id = Sequence (lambda n: n)
user_id = ????
class Meta:
model = Post

What goes into my `user_id` field?

Are there any reasons to use Flask-Bcrypt over passlib with bcrypt?

I am used to using passlib with bcrypt to hash passwords. It seems like the Flask-Bcrypt extension is very popular to use with Flask, but are there any specific reasons I should use that over passlib? At a quick glance, they seem to do the same thing, but also low level encryption isn't really my strong area. Thanks for any advice.
