age=20, ?
Yeah it's a integer type. Anything wrong?
Yashwant
Yashwant
And also why is this happening?
Yashwant
>>> from signup.models import User
>>> User.objects.all()
<QuerySet []>
Yashwant
Even though I've defined
def __str__(self):
return self.first_name + ' - ' + self.last_name
I'm getting <QuerySet []> instead of First & Last names
Anonymous
Oh
Ghazwan
Even though I've defined

Do you have any entries in your DB ?
Yashwant
a = new User(first_name="Random", last_name="Person", birth_date=1897-12-17, age=20, email="random@xyz.com", number=1234567890, profession="Job xyz", hobbies="Working", location="Earth")
I'm trying to enter them, but getting that indent error
Ghazwan
I'm trying to enter them, but getting that indent error
As Sinatra said, where did this new come from ?
Yashwant
I'm initializing the class to actually use it
Yashwant
And if I don't use new, I get invalid syntax error
Ghazwan
a = new User(first_name="Random", last_name="Person", birth_date=1897-12-17, age=20, email="random@xyz.com", number=1234567890, profession="Job xyz", hobbies="Working", location="Earth")
Your code is formatted badly in here, why age=20 is not highlighted here ? there maybe be something wrong about it.
Ghazwan
Enter some info to your DB ? do that in your admin page
Yashwant
What are you trying to do anyway ?
I'm just trying to check if DB is taking any info/entries
Yashwant
Your code is formatted badly in here, why age=20 is not highlighted here ? there maybe be something wrong about it.
Can you tell me in what way should I pass the age in?
Ghazwan
I'm just trying to check if DB is taking any info/entries
python manage.py createsuperuser
>>> enter valid information
python manage.py migrate
python manage.py makemigrations
go to your local_host/admin
Yashwant
python manage.py createsuperuser
>>> enter valid information
python manage.py migrate
python manage.py makemigrations
go to your local_host/admin
But what's the point of this? I'm trying to add a person's profile into my system. This is more like adding users to the administration :/
Ghazwan

No, open the admin page and you will know it all.
Yashwant
That's what I have.
Ghazwan
No, open the admin page and you will know it all.
also if you do want to quickly test your DB, use fake library in order to populate it.
Yashwant
No.
Ghazwan
then ? what is it ?
Ghazwan
custom users model ?
Ghazwan
Why ?
Ghazwan
you don't have to do all that, there is a default user model that is doing that for you.
Yashwant
😂 but the point of my project is to make all the fields
Yashwant
"Personal Profile Management System"
Ghazwan
try using () with those integerfields
Yashwant
Ok.
Yashwant
try using () with those integerfields
Ok, so there's something wrong with age. How should I define it?
Ghazwan
all your class members should have those () actually.
Anonymous
Ok, so there's something wrong with age. How should I define it?
not only age but also number
Ghazwan
Yeah every integerfield
Yashwant
Which is weird, it didn't throw any error
Ghazwan
Which is weird, it didn't throw any error
that is python, it never throw an error before the line is executed unlike compiled languages.
Anonymous
number worked
if u swap those two lines of codes, then number would throw error while age wouldn't say anything
Yashwant
Yeah, I get the point now. But for a minute let's not consider number and age...
And I've passed
a = User(first_name="Random", last_name="Person", birth_date=1897-12-17, email="random@xyz.com", profession="Job xyz", hobbies="Working", location="Earth")
as my values. When I call an individual entity/value, say a.first_name() why do I get object not callable? What am I doing wrong?
Anonymous
because first_name is not a function
Anonymous
its a field not a method
Yashwant

OMFG what am I even doing. Shit 😐
Dumb question. My bad!

I am using weasy for convert html to pdf

but I cant import any fonts or image. How can I do that?

Well, I have built already a Database from scratch, but I would like to know if "python manage.py inspectdb" integrates smoothly that database, with the new django's app.
Right now, I'm just following the official django's tutorial, but it emerged that question to my brain somehow 😆
thats gonna be a lot and harder work than create new django models. but first step to do one of them you still need understanding about django models
inchidi
Even though I've defined
def __str__(self):
return self.first_name + ' - ' + self.last_name
I'm getting <QuerySet []> instead of First & Last names
there's two different things in django, queryset and model object. when you override magic method __str__, thats means you will get returned value when you call the model object as string
inchidi
MyModel.objects.all() return queryset
MyModel.objects.filter() return queryset
MyModel.objects.get() return model object
inchidi
so you are not getting "first _name - last_name" because you are calling queryset and its empty queryset

New to Django? here is some resource to start

Yashwant
so you are not getting "first _name - last_name" because you are calling queryset and its empty queryset
So what should I be using?
inchidi
can you post the text version of User(...) here so i can easily fix it?

inchidi
oh wait, is this User from django.contrib.auth.models?
Yashwant
No.
inchidi
so its you own User models right?
inchidi
how is you User model class looks like?
Yashwant
Basically, what my project is, is I have to create a Personal Profile Management System, so that a user can fill out those fields and can edit them at any point later on, when it's necessary. All these details are protected by giving the user a username & a password, for modifying & viewing their details.

okay i will suggest you how to make something like this but its not gonna be similar with your approach
Yashwant
Sure, I'm open to suggestion!

I chose this way, cause I was actually following a video & doing my project parallely. Although that video series was of a different app/service.
inchidi
replace your User model with this:
class UserProfile(models.Model):
user = models.OneToOneField(User, on_delete=models.CASCADE)
birth_date = ...
age = ...
number = ...
profession = ...
hobbies = ...
location = ...``

class UserProfile(models.Model):
user = models.OneToOneField(User, on_delete=models.CASCADE)
birth_date = ...
age = ...
number = ...
profession = ...
hobbies = ...
location = ...``
So that, if I delete any entity the entire user will be removed, correct?
inchidi
So that, if I delete any entity the entire user will be removed, correct?
not entire user, if you delete one User, its UserProfile gonna be deleted too
Yashwant
Ohh ok!
inchidi
when you want to create new user and its profile do this:
>>> from django.contrib.auth.models import User
>>> from yourapp.models import UserProfile
>>> usr= User.objects.create_user(username="test1",password="yourstr0ngP4ss",email="email@email.com",first_name="Yash",last_name="want")
>>> UserProfile.objects.create(user=usr, ...)
inchidi
add
from django.contrib.auth.models import User
on top
inchidi
django User model already have its own email, first_name, last_name fields
inchidi
so you dont need those fields on your UserProfile
Yashwant
So just remove those fields? Ok!
inchidi
yeah, dont forget to makemigrations and migrate
Yashwant
Yep!
Yashwant
when you want to create new user and its profile do this:
>>> from django.contrib.auth.models import User
>>> from yourapp.models import UserProfile
>>> usr= User.objects.create_user(username="test1",password="yourstr0ngP4ss",email="email@email.com",first_name="Yash",last_name="want")
>>> UserProfile.objects.create(user=usr, ...)
>>> UserProfile.objects.create(user=usr, ...)
What's this for? And when should I use it?
inchidi
you dont need import UserProfile, you are creating it there and you have typo in your class name
