Django prevent users from editing their own record in admin
In Django I have model called Loans. I want users to be able to edit a loan created by someone else, but not if they created it themselves. As a bonus, I would like staff members not to be able to edit loans that belong to other staff. How can I do this? I really have no idea. I tried creating custom validation, then I tried a manger like this: from django.db import models from django.core.validators import MaxValueValidator, MinValueValidator from core.models import User class LoanManager(models.Manager): def create_loan(self, request, borrower, approved, start_date, term_in_months, principal, interest_rate_pa, **extra_fields): """Creates and saves a new loan""" print('USER========================================', request.user) if borrower != request.user: raise ValueError("Staff may not lend to themselves or other staff") return super(LoanManager, self).create(borrower=borrower, approved=approved, start_date=start_date, term_in_months=term_in_months, principal=principal, interest_rate_pa=interest_rate_pa,**extra_fields) class Loans(models.Model): borrower = models.ForeignKey(User, on_delete=models.CASCADE) approved = models.BooleanField(default=False) start_date = models.DateField(auto_now_add=True) term_in_months = models.IntegerField(validators=[ MaxValueValidator(360), MinValueValidator(24) ]) principal = models.IntegerField(validators=[ MaxValueValidator(1000000), MinValueValidator(2000) ]) interest_rate_pa = models.DecimalField(max_digits=5, decimal_places=2) objects = LoanManager() Nothing I do seems to prevent users creating loans for themselves and editing them! -
Is there any way of mentioning two login_redirect_urls in django?
In my application, if the user logs in for the first time, he is redirected to the profile page and from the second time, he is redirected to the homepage (VChome in my appliation). So I decided to write this in urls.py and views.py urls.py from django.urls import path from . import views urlpatterns = [ path('VC/',views.VChome, name='VChome'), path('profile/',views.update_profile,name='profile'), path('users/login/', views.login_user, name='login'), ] views.py def login_user(request): logout(request) username = password = '' if request.POST: username = request.POST['username'] password = request.POST['password'] userLL = CustomUser.objects.get(username=username) last_login = userLL.last_login user = authenticate(username=username, password=password) if user is not None: if user.is_active: login(request, user) if last_login==None: return HttpResponseRedirect(reverse("profile")) else: return HttpResponseRedirect(reverse("VChome")) return render(request, 'login.html') login.html <!DOCTYPE html> <html lang="en"> <head> </head> <body> {% block content %} <form method="post"> <strong><p>Sign in</p></strong> <p>Username</p> {% csrf_token %} <input type="text" id="username" name="username" placeholder="Username"> <p>Password</p> {% csrf_token %} <input type="password" name="password" id="password" placeholder="Password"> <input type="submit" value="Login"> </form> {% endblock %} </body> </html> I have templates profile.html and VChome.html and I'm sure that they are rendered correctly in views.py The problem here is if I mention LOGIN_REDIRECT_URL = 'VChome', the login page is redirected to VChome. If I don't mention it, login page is redirected to /accounts/profile I want the login … -
Making a Django page visible only to confirmed emails
I'm trying to add a feature to my site where a certain part of the site can be used only by users who confirmed their email account. I found a solution, but it's not working. Here is what i did: I have been suggested to add a separate model for this: class account_emailconfirmation(models.Model): user = models.OneToOneField(User, on_delete=models.CASCADE) @property def has_verified_email(self): return self.user.emailaddress_set.filter(verified=True,primary=True).exists() And this is what the template looks like: {% extends "main/header.html" %} {% if user.profile.has_verified_email %} {% block content %} <style> </style> <body> <div> <p>Here goes a bunch of features</p> </div> </body> {% endblock %} {% else %} <p> Your email is ot confirmed </p> {% endif %} But it's not working, since i can see the page even without having to confirm my email. Here is what my db looks like: There is a table called account_emailconfirmation, then there is an index, verified, that will give 0 when the account is not verified, 1 when it is verified. Any advice is appreciated! -

How to loop through django formset id in jquery?
My model: class Stock_total(models.Model): purchases = models.ForeignKey(Purchase,on_delete=models.CASCADE,null=True,blank=False,related_name='purchasetotal') stockitem = models.ForeignKey(Stockdata,on_delete=models.CASCADE,null=True,blank=True,related_name='purchasestock') quantity_p = models.PositiveIntegerField(default=0) rate_p = models.DecimalField(max_digits=10,decimal_places=2,default=0.00) disc_p = models.DecimalField(max_digits=10,decimal_places=2,default=0) total_p = models.DecimalField(max_digits=10,decimal_places=2,default=0.00,null=True,blank=True) This model performs a inline_formset with the Purchase model.. So as every one knows the id of the fields in an inline_form is not same for every field it increase in number as we go down or add a form. For example: The id for the form field quantity_p in the 1st line of form is id_purchasetotal-0-Quantity_p and in the second line of form is id_purchasetotal-1-Quantity_p (** Notice the number changes as we increase the line of a formset) My question is that how to loop over the id of a formset in jquery as because I have to perform some calculation in my form: I want to perform something like this but inside a for loop: <script type="text/javascript"> $(document).ready(function(result){ if($("#id_purchasetotal-0-Disc_p").val() != ''){ $('#id_purchasetotal-0-Quantity_p, #id_purchasetotal-0-rate_p, #id_purchasetotal-0-Disc_p').on('change', function() { $('#id_purchasetotal-0-Total_p').val($('#id_purchasetotal-0-Quantity_p').val() * $('#id_purchasetotal-0-rate_p').val() * (1 - ($("#id_purchasetotal-0-Disc_p").val()/100))); }); } else { $('#id_purchasetotal-0-Quantity_p, #id_purchasetotal-0-rate_p').on('change', function() { $('#id_purchasetotal-0-Total_p').val($('#id_purchasetotal-0-Quantity_p').val() * $('#id_purchasetotal-0-rate_p').val()); }); } }); </script> Any idea how to do this?

Can I arbitrarily replace and restore the db.sqlite3 file?
I know that the file db.sqlite3 in Django holds the entire database and the entire content within it. Is it safe to keep all the project files, the *.py files, the migrations files, but replace the db.sqlite3 file with a different one. If both these db.sqlite3 files work on the same database model, with the same tables, rows, columns, and everything, then if I swap out that file it should work seamlessly. I want to copy the original db.sqlite3 file into a different directory. Then I want to create a new db.sqlite3 file in my project. Then I want to work with the new database file, and give it other data to test how the project would work with it. Then I want to delete the new db.sqlite3 file, and I want to restore the old one, which I've saved into another directory. Would that work? And how can I create a new db.sqlite3 file, a clean state to put test data into? Also, what if I build my project on another sever, can I copy my old db.sqlite3 file there too, and have the database with all it's saved data restored?
