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?.

Django DRF + Djoser reset activation code

I have been successfully able to setup a Django app with Djoser token based authentication. I want to generate a activation code / url and make the user activate through that code / link for account activation or reset password.

The [Base Endpoints](https://djoser.readthedocs.io/en/latest/base_endpoints.html#user-resend-activation-e-mail) explains how to enable and utilize the activation using the endpoints. But how do I get to create the db models and generate activation code for the users? Am I missing something ?

KeyError: 'id' in django rest framework when trying to use updateorcreate() method



I am trying to update the OrderItem model using update_or_create() method. OrderItem model is related to the Order model with many to one relationship ie with a Foreignkey.

I am trying to query the orderitem object using id and update the related fields using default as you can see, but got this error.

Setting up Django with uWSGI and nginx - I've been trying to figure this out for 5 days now. Please help...

I'm trying to set up nginx server with my django app and uWSGI, by following this tutorial: https://uwsgi-docs.readthedocs.io/en/latest/tutorials/Django_and_nginx.html
I've been able to follow it up until the socket testing. The test itself doesn't produce an error, but localhost:8000 always returns 502 bad gateway error. I have been troubleshooting this for hours but can't figure out what I'm doing wrong.

/etc/nginx/nginx.conf:
```

How to make a thread to make 100 concurrent request to db in Python ?

I want to simulate 120 people booking 120 seats all at once, how should I do that!!

This is what I am doing for the same

for i in range(120):
thread = Thread(target=book, args=(GetUser(i),)).start()
thread.join()

This is what my book function looks like:

def book(user): #user -> airline.User, seat -> airline.Seat
print(user1 + "with id " + str(user0) + " trying to book seat ")
seats = availableseats()
print("Total Available seats: " + str(seats[0]))

#selecting the seat at random
seat = random.randint(1, seats[0])
seat = GetSeat(seat)
print("Seat selected: " + str(seat[1]))
mycursor.execute("UPDATE seats SET USERID = " + str(user0) + " WHERE id = " + str(seat0))
mydb.commit()

But with this approach I am getting 2

Runtime error: working outside of app context - confused by this

I've got the error above when I try execute a simple:
>User.query.all() #User is a model

This works fine on one device/environment. I can query in the app.py file, or from another file by importing app and User from app.py

I pushed to git, cloned the repo, and now I get this error when running the line above on a different device and environment. The app itself will run, but not the queries.

I'm confused as to why the same code would work on one env but not another, if it was dependency related wouldn't I be getting 'module not found' or something else, not this runtime error?

How to refresh a div without refreshing the whole page ?

I have a view that is used to block and unblock users. In my template all the users are listed inside a table. What I want to do is I want to refresh a specific portion of the div rather than the whole page while clicking block and unblock user. How to do that?

&#x200B;

views.py

&#x200B;

def block_user(request, id):

blocked_user = MyUser.objects.get(id=id)

blocked_user.is_active = False

blocked_user.save()

print("Blocked user is", blocked_user)

print("Is active status of blocked user is", blocked_user.is_active)

return redirect("usermanager")

&#x200B;

&#x200B;

def unblock_user(request, id):

user_to_unblock = MyUser.objects.get(id=id)

user_to_unblock.is_active = True

user_to_unblock.save()

print("Unblocked user is", user_to_unblock)

print("Is active status of blocked user is", user_to_unblock.is_active)

return redirect("usermanager")

Cant register users using this view with REST (Invalid password format or unknown hashing algorithm)

@api_view(['POST'])
def register(request):
serializer=UserSerializer(data=request.data)
if serializer.is_valid():
serializer.save()
#user=User.objects.create_user(username=request.data['username'])
#user.set_password(request.data['password']) #hash password
#user.save()
user=User.objects.get(username=request.data['username'])
token=Token.objects.create(user=user) #create token
return Reponse({"token":token.key, "user":serializer.data})
else:
return Response(serializer.errors)

Everything commented is something i tried before

imports:

from django.contrib.auth.models import User
from rest_framework.authtoken.models import Token

User serializer:

class UserSerializer(serializers.ModelSerializer):
class Meta(object):
model= User
fields = ['id','username','password','email']

Send email with Flask

Hello everyone, does anyone know why I can only send emails to my email, which is where the app was created? When I try to send a message to another email, I don't get any error, but the email doesn't arrive. You can see the code in the pictures.

project.config'MAIL_SERVER' = 'smtp.gmail.com'
project.config'MAIL_PORT' = 465
project.config'MAIL_USERNAME' = 'my email'
project.config'MAIL_PASSWORD' = 'app password'
project.config'MAIL_USE_SSL' = True
project.config'MAIL_USE_TLS' = False

Or here:


def renderregistration():
message = ''
if flask.request.method == "POST":
emailform = flask.request.form"email"
numberform = flask.request.form["phonenumber"]
nameform = flask.request.form["name"]
surnameform = flask.request.form"surname"
mentorform = flask.request.form["mentor"]

What could I have done better here?

Hi, I'm pretty new to Python, and actual scripting in general, and I just wanted to ask if I could have done anything better here. Any critiques?
