How do i filter Django list using my bootstrap form?

I have been using Django and its default admin templates for my app. There is a certain list view for which I have decided to create my own bootstrap form for filtering objects. I want the values in the form fields to be used to filter on the queryset. How do I POST the data to Django and tell it to reload the page bearing in mind the choices in the form? Basically, how do I tell Django to "refresh this page" but apply the values in the form to queryset? Here is my code for the customized list

{% extends 'admin/change_list.html' %}

{% load i18n admin_urls static admin_list %}
{% block extrastyle %}
{{ block.super }}
<link rel="stylesheet" type="text/css" href="{% static "admin/css/changelists.css" %}" />

{% if cl.formset %}
<link rel="stylesheet" type="text/css" href="{% static "admin/css/forms.css" %}" />
{% endif %}
{% if cl.formset or action_form %}
<script type="text/javascript" src="{% url 'admin:jsi18n' %}"></script>
{% endif %}
{{ media.css }}
{% if not actions_on_top and not actions_on_bottom %}
<style>
#changelist table thead th:first-child {width: inherit}
</style>
{% endif %}
{% endblock %}

{% block content_title %}
<h1> Activity Summary </h1>

Registration form shows too many fields after I make custom register form model

I'm trying to make a custom registration form, but am running into trouble.

My `forms.py` has this:

class RegisterForm(UserCreationForm):
'''
Form that makes user using just email as username
'''
error_messages= {
"password_mismatch": _("Passwords do not match."),
"duplicate_email": _("Email already exists."),
"unique": _("Email already exists"),
}
register_username= forms.EmailField(label=_("Email"), widget=forms.TextInput(attrs={"placeholder":"Email"}))
register_password1= forms.CharField(label=_("Password"), widget=forms.PasswordInput(attrs={"placeholder":"Password"}))
register_password2= forms.CharField(label=_("Password confirmation"), widget=forms.PasswordInput(attrs={"placeholder":"Confirm password"}))

def clean_username(self):
username = self.cleaned_data["username"]
try:
User._default_manager.get(username=username)

#if the user exists, then let's raise an error message
raise forms.ValidationError(self.error_messages['duplicate_email'], #user my customized error message
code='duplicate_email', #set the error message key
)
except User.DoesNotExist:
return username # great, this user does not exist so we can continue the registration process

class Meta:
model= User
fields= ("username",)

My `views.py` looks like this:

def login_register(request, template="pages/login_register.html"):
registration_form= RegisterForm()
return render(request, template, {"registration_form": registration_form})


Which leads to my registration form in `login_register.html` rendering like this:

<form method="post">
<input type="hidden" name="csrfmiddlewaretoken" value="CSRF-TOKEN-HERE">
<p><input autofocus="" id="id_username" maxlength="150" name="username" type="text" required=""></p>
<p><input id="id_password1" name="password1" type="password" required=""></p>
<p><input id="id_password2" name="password2" type="password" required=""></p>
<p><input id="id_register_username" name="register_username" placeholder="Email" type="text" required=""></p>
<p><input id="id_register_password1" name="register_password1" placeholder="Password" type="password" required=""></p>
<p><input id="id_register_password2" name="register_password2" placeholder="Confirm password" type="password" required=""></p>
<button class="btn btn-primary" type="submit">Register</button>
</form>


I only want the last three `input` tags to be used. My goal is for my registration form to have three fields: Email, password, and password confirmation. Why is Django loading the three extra top `input` fields and how do I prevent that?

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

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 ?

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

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?

@api_view(['POST'])
def register(request):
serializer=UserSerializer(data=request.data)
if serializer.is_valid():

token=Token.objects.create(user=user) #create token
return Reponse({"token":token.key, "user":serializer.data})
else:

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):

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_USERNAME' = 'my email'
