How to use django default login
I'm trying to use django's default admin login function. This works for logging out, i.e. putting in html: <a href="{% url "log_out" %}"> and in urls.py: from django.contrib.auth.views import LoginView, LogoutView path("log_in/", LoginView.as_view(), name="log_in"), path("log_out/", LogoutView.as_view(), name="log_out"), clicking on the logout link takes the user to the django logout page and works correctly. But trying to do the equivalent to log in, i.e.: <a href="{% url "log_in" %}"> causes a TemplateDoesNotExist error. I would like to use django's default login page rather than creating my own template - how can i do this? -
How can I put the search by at the end ? django, bootstrap5
I'm making a simple website using django and bootstrap5. I've tried the class="de-flex justify-content-end" to put my search by at the end but it doesn't work. this is what it looks like: Here is the code: <body> <nav class="navbar navbar-expand-lg navbar-dark bg-dark"> <div class="container"> <a class="navbar-brand" href="{% url 'my_websites:home' %}"> my website </a> <button class="navbar-toggler" type="button" data-bs-toggle="collapse" data-bs-target="#navbarNav" aria-controls="navbarNav" aria-expanded="false" aria-label="Toggle navigation"> <span class="navbar-toggler-icon"></span> </button> <div class="collapse navbar-collapse" id="navbarNav"> <ul class="navbar-nav"> <li class="nav-item"> <a class="nav-link" href="{% url 'my_websites:about_me' %}"> About Me </a> </li> <li class="nav-item"> <a class="nav-link" href="{%url 'my_websites:blog' %}"> Blog </a> </li> <li class="nav-item"> <a class="nav-link" href="{% url 'my_websites:contact' %}"> Contact </a> </li> <li class="nav-item dropdown"> <a class="nav-link dropdown-toggle" href="#" id="navbarDropdownMenuLink" role="button" data-bs-toggle="dropdown" aria-expanded="false"> More </a> <ul class="dropdown-menu" aria-labelledby="navbarDropdownMenuLink"> <li><a class="dropdown-item" href="#">Join our club!</a></li> <li><a class="dropdown-item" href="#">Membership</a></li> <li><a class="dropdown-item" href="#">Be Ullie's friends!</a></li> </ul> </ul> <form class="d-flex justify-content-end"> <input class="form-control me-2" type="search" placeholder="Search" aria-label="Search"> <button class="btn btn-outline-success" type="submit">Search</button> </form> </div> </div> </nav> How do i put the search bar at the end? thank you very much for your response in advance! -
SMTPConnectError at [url] : (421, b'Server busy, too many connections') - Django email
I have a simple method (send_activation_email) called from a view which handles user registration by extending default django user auth. It sends an activation email. Now I get the error: SMTPConnectError at /accounts/register/ - (421, b'Server busy, too many connections') the method implementation: def send_activation_email(user, request): current_site = get_current_site(request) subject = 'Activate your membership Account' message = render_to_string('accounts/account_activation_email.html',{ 'user': user, 'domain': current_site.domain, 'uid': urlsafe_base64_encode(force_bytes(user.pk)), 'token': account_activation_token.make_token(user), }) html_message = get_template('accounts/account_activation_html_email.html').render({ 'user': user, 'domain': current_site.domain, 'uid': urlsafe_base64_encode(force_bytes(user.pk)), 'token': account_activation_token.make_token(user), }) send_mail(subject=subject, message=message, from_email= None, recipient_list=[user.email], html_message= html_message #,fail_silently=False ) I have never come across this issue before and have not found any useful answers searching on here.

Recommend chatbots similar to CakeChat by LukaLabs
I am currently working on a project to make a Django application that recommends songs based on the tone of the conversation between the user and the chatbot. I had initially planned to use CakeChat, but the project seems to be archived and will not run. I have looked into other options like GPT-3 by OpenAI but am unsure how it will work for my purpose and how to use it. Please recommend options that I can use. I will submit this as my final year graded project in 2 weeks. -
Which Database should I use for developing a Cloud Accounting System like FreshBooks?
I would like to develop a cloud based accounting system with Django. I am planning to use a microservice based architecture. The app will have All-In-One functinalities like: Invoicing Accounting Payments Project Management Client Management etc I understand SQL based databases are best for storing data that are highly relational. But for scalability NOSQL is best. Could you help me decide which one to go for? Thanks. Basically I am looking to make a clone of Freshbooks but with microservice architecture for educational puroposes. -

Django Rest Framework: How to make relative URLs clickable?
By passing an empty request to the context of ViewSet, it's possible to have the instance URLs rendered as relative URLs instead of absolute (i.e. the host is omitted). However, when https:// is missing from the URL DRF does not render the string as a clickable URL which makes jumping from one resource to the other rather difficult. -

Speed up Django bulk_create with unique fields
I have a database with thousands of entries. Each entry has a unique field that I called unique_id and it's calculated on some other fields: class ModelA(models.Model): name = models.CharField(max_length=256, help_text="Type a name") created_at = models.DateTimeField(auto_now_add=True) unique_id = models.CharField(max_length=256, unique=True, editable=False, default=calculate_my_unique_id) This is the algorithm I'm using to prevent duplicates (omitting a bit of code): objectsToAdd = [] items_dict = ModelA.objects.in_bulk(field_name='unique_id') unique_id = generate_unique_id() if unique_id not in items_dict.keys(): objectsToAdd.append( ModelA( name=item_name, unique_id=unique_id ) ) if objectsToAdd: ModelA.objects.bulk_create(objs=objectsToAdd) The problem is that when table items grow, will grow also item_dict list and consequently the check time. Is there a more efficient way to simply skip duplicates from bulk insert? -

Image sometimes does not display in HTML page (Django 3.0)
I created a somewhat clone of Instagram main page (for full transparency, please know that I do this for a psychological experiment). One of my users got a very strange bug : when going on my page, two images seemed to not be loaded (there was no broken link, and the images simply appeared to be skipped, see illustration below). Images not displaying illustration On reloading the page, the images indeed appeared normally, and other users did not get any bug. The thing is, I do not quite understand how this could happen, since I show the page only when all resources are loaded, through these lines of code : window.addEventListener('load', function () { document.getElementById("main-page").style.visibility = "visible"; }); Please find the code for the page below (I removed navbar code for lisibility, please let me know if full version is needed). <body id="main-page" style="visibility:hidden"> <section class="main"> <div class="wrapper"> <div class="left-col"> {% include 'instapp/status.html' %} {% include 'instapp/post.html' %} </div> <div class="right-col"> {% include 'instapp/recommandations.html' %} </div> </div> </section> <script> window.addEventListener('load', function () { document.getElementById("main-page").style.visibility = "visible"; }); </script> </body> And here is the code for displaying a single post : {% load static %} <div class="post"> <div class="info"> <div class="user"> … -
Django table connection based on the value type
I really want some help with this problem, because somehow I cannot solve it. The problem: I have a Parameter table, which is stores parameters I want to store the values in different parameters, based on the type of the parameter These are the type models: class JsonParameter(models.Model): value = models.JSONField() class StringParameter(models.Model): value = models.CharField(max_length=100) class DateParameter(models.Model): value = models.DateField() And I have a parameter model: class Parameter(TimeStampedModel): name = models.CharField(max_length=64) is_mandatory = models.BooleanField(default=True) value = SomekindOfMagic() So if I would like to create some parameters, like this param_1 = Parameter.objects.create(name="name of the param", is_mandatory=True, value="This is a string value") param_2 = Parameter.objects.create(name="name of the param", is_mandatory=True, value='{"object": "string"}') param_3 = Parameter.objects.create(name="name of the param", is_mandatory=True, value="2022-03-20") The param_1.value will be saved into the StringParameter table, the param_2.value will be saved into the JsonParameter table, and the param_3.value will be saved into the DateParameter table and the Parameter.value will contain a foreign key like object. Can I use the generic foreign key for this? Or do I have to use something else ? There is any solution for this ? Thanks guys :) -
