Check for password before accessing content in django
I am trying to build a functionality where users have to enter the passcode to access the site. If you go to this site it will ask for a password (123) before showing you the content: https://www.protectedtext.com/djangoproj I want to do it without forms.py. URL OF THE PAGE --> TEMPLATE --> ASK FOR PASSCODE --> SHOW CONTENT IF PASSCODE MATCHES models.py from django.db import models # Create your models here. class Text(models.Model): text = models.TextField(blank=True) slug = models.SlugField(unique=True) password = models.CharField(max_length=50) def __str__(self): return self.slug views.py from django.shortcuts import render from .models import Text import django.contrib.auth # Create your views here. def textview(request, slug): obj= Text.objects.get(slug=slug) return render(request, 'text/textpage.html', {'obj' : obj}) def home(request): return render(request, 'text/index.html', {}) I have tried creating a new template for password but I am still not getting that functionality. Thanks in advance -
How do i extend Django's auth user manager to add a method of my own?
I'm using Python 3.9 and Django 3.2. I want to use Django's auth module for basic user management and have added this in my settings.py file INSTALLED_APPS = [ 'django.contrib.admin', 'django.contrib.auth', 'django.contrib.contenttypes', 'django.contrib.sessions', 'django.contrib.messages', 'django.contrib.staticfiles', 'cbapp', ] However, I woudl like to change the primary key of its user table to be a UUID and then add my own method, so I created this file at models/custom_user.py from django.contrib.auth.models import AbstractUser from django.db import models class CustomeUserManager(models.Manager): def get_active_users(self): qset = CustomUser.objects.filter( is_active=True ) return list(qset) class CustomUser(AbstractUser): pass uuid = models.UUIDField(primary_key=True, default=uuid.uuid4, editable=False) objects = CustomeUserManager() I would still like to have access to Django's original auth methods though, but it seems like I can't access them anymore, for example "create_user" ... >>> user = CustomUser.objects.create_user('Dave', 'myemail@test.com', 'johnpassword') Traceback (most recent call last): File "<input>", line 1, in <module> user = CustomUser.objects.create_user('Dave', 'myemail@test.com', 'johnpassword') AttributeError: 'CustomeUserManager' object has no attribute 'create_user' What's the proper way to extend Django's auth user methods while adding some of my own? -
Django rendering <a> tag with double underline
I am finishing my first project using Django (a blog). I first made the front-end using HTML and CSS and everything was smooth. I used an identical copy of the CSS file. When rendering the same HTML template using Django, it shows double underline animation under the tag. The code used: <div> <ul id="underline"> <li class="nav-items-lis"><a href="#" class="nav-items">Posts</a></li> <li class="nav-items-lis"><a href="#" class="nav-items">About</a></li> <li class="nav-items-lis"><a href="#" class="nav-items">Blog</a></li> <li class="nav-items-lis"><a href="#" class="nav-items">Contact</a></li> </ul> </div> The Django template: <div> ... </div> <div> <ul id="underline"> <li class="nav-items-lis"><a href="#" class="nav-items">Posts</a></li> <li class="nav-items-lis"><a href="#" class="nav-items">About</a></li> <li class="nav-items-lis"><a href="#" class="nav-items">Blog</a></li> <li class="nav-items-lis"><a href="#" class="nav-items">Contact</a></li> </ul> </div> <div class="container"> <div class="card-wrapper"> {% block body %} {% endblock %} </div> The code related to tags is the same in both (the HTML code and the Django template). Any hints on how to solve this issue? -
Django error when running migrate - id null
I am trying to make new migration for my django project after adding and removing some columns in table called payment. When running python manage.py makemigrations, everything working fine, and it results in new migration file 0002_auto_20211107_1714.py. Next, I try to run python manage.py migrate and it result in this error File "/home/.local/lib/python3.8/site-packages/django/db/backends/utils.py", line 84, in _execute return self.cursor.execute(sql, params) psycopg2.errors.NotNullViolation: null value in column "id" violates not-null constraint DETAIL: Failing row contains (null, payment, 0002_auto_20211107_1714, 2021-11-07 17:14:11.036703+00). Anyone ever faced this problem? -
What's the proper way to check in a Model's save() method if a FileField was committed in Django?
In Django, if you are overriding the save method of a model with a FileField, you can do something like this: class MyModel(models.Model): my_file = models.FileField() def save(self, *args, **kwargs): if self.my_file and not self.my_file._committed: # The file changed This lets you detect anytime a new file is uploaded. This can either happen if a new instance of MyModel is being created, or one is being modified, and a new file is replacing an old file (or no file). This is very convenient for cases where you need to read the file, and do something, but only if the file changed. This works, but the slight problem is that the my_file._committed attribute starts with an underscore, indicating that it's not meant to be used outside of the class it's defined in. Is there a proper way to detect if the file in the FileField changed during the current save() operation without using the private _.committed attribute? -
first_name is added to the tuple
Im using django-allauth. I added more fields in form (firstn_name and last_name) in form: myapp/forms.py class CustomSignupForm(forms.Form): first_name = forms.CharField(max_length=30, label="first_name", strip=True, widget=forms.TextInput(attrs={'placeholder': "name", })) last_name = forms.CharField(max_length=30, label='last_name', strip=True, widget=forms.TextInput(attrs={'placeholder': 'last_name',})) def signup(self, request, user): user.first_name = self.cleaned_data['first_name'], user.last_name = self.cleaned_data['last_name'] user.save() return user after which I specified a link to this form in the settings. When registering, these two fields appeared, but: Now, when registering, my first_name is in the tuple. I output in the template: {{user.first_name}} Last name is displayed normally. What can be done so that the first name is not in a tuple, but just a string? -
Pagination codes is not working with annotate

Eurodns + Django + Dynamic Ip
I bought an domain from Eurodns and wanted connect it with my first website on my computer at home. (I'm a noob - just starting to understand how programming works.) Long story short, when I write my URL it doesn't reach my website, nor if I type www.site.com nor if I type only site.com. (when I type with www. it shows me some kind of default page by eurodns I think. The none www. shows this site can't be reached) What I have tried. I installed a VM ubuntu server on a proxmox with django project and apache2. Then as a first test I used an free domain from noip with their dynamic-Ip tool. It worked just fine without doing any special setup (I might changed a port in apache settings but don't remember for sure). I portforwarded port 80 and 443 from router to my port from the webhost. Then I tried to make the website be rendered by accessing my custom domain bought from Eurodns, via a ddclient/Dynamic DNS offered by Eurodns. For some reason this doesn't work at all. I tried in the meantime to solve the SSL certificate - did this screw things up? Also activated … -
How to access a Django UpdateView with using a uuid as slag

JavaScript addEventListner Django question
I have a Django website that has a Form made up of multiple fields. Within this form, I am adding two new fields that I like to be able to keep adding values to which get submitted to the database. The primary form is used to populate a city name, address, etc. the new fields are used to populate event names and dates. For example, I add Machester as the city and then I'd like to add as many events to Manchester as I like. At the moment I have a JavaScript addEventListener setup for the submit button of the primary form which will POST all fo the fields i specify, but this refreshes the page everytime i SUBMIT I need to keep the city name field populated so that each event added will contain the city name and the additional event name and event date fields. Ultimately I want a table with City, EventName and EventDate and a table with the city details. So im wondering how i do this with JavaScript to only submit the city, event name and event date? I tried to create a new form within a form and reference that with a different js … -

image url redirect Django
Is there any way of redirecting an image's URL via views, so that Django isn't having to serve the image directly? The background to my questions has to do with image tracking, which for obvious reasons requires a trip to the Django server. For example, I have a webpage with, say, <img src="https://mydjangoserver.com/image-url/image.jpg"> Which is passed to views at which point the src url is redirected to, say, https://my-nginx-server.com/image.jpg and the image is then loaded within the original html page. I've seen code for forcing a file download using X-Accel-Redirect, but I cannot get it to work. Here is a view that I've been playing around with, but without success: def image_url(request): file_name = 'image.jpg' path_to_file = 'https://my-nginx-server.com/' response = HttpResponse(content_type="image/jpg") response['Content-Disposition'] = f'inline; filename={smart_str(file_name)}' % response['X-Accel-Redirect'] = smart_str(path_to_file) return response Any advice on how to redirect the images url would be very much appreciated. -
