Is it necessary to use serializes in Django rest framework?
Is it necessary to use serializers in Django rest? I'm building a project where I came across a scenario where fields in forms add dynamically and then I need to validated and save data into DB. Since fields in forms dynamic, How can we handle this in serializer? Can we do validations and saving without using serializes? -

creating a new instance of todolist in every URL
I want to upgrade my todolist app so that users can create a link to their own todolist. for example, they can do 127.0.0.1/room/testroom and it'll take them to a todo list. Another use can do 127.0.0.1/room/testroom2 will take them to a new room with another instance of the todo list. I'm not sure how to implement this feature. I already have one app set up for the main todo app functionality. I'm in the progress of writing the ROOMS app which will let users create rooms. I don't know how to mix both models from different apps, or should I put them all in the same app? -
Getting self.pk from DetailView for lte/gte comparison (Django)
Goal: Implement next article / previous article feature on article page which is being served via DetailView. Compare current article pk against queryset in order to grab the next and previous articles. I've tried a lot of different methods so far, but I'm getting errors on all of them. ''' class PostDetail(generic.DetailView): model = Post template_name = 'post_detail.html' def get_context_data(self, **kwargs): context = super(PostDetail, self).get_context_data(**kwargs) pk = Post.objects.filter(pk=self.kwargs.get('pk') ''' I've also tried: pk = self.kwargs.get('pk') and pk = self.kwargs['pk'] I get KeyError on the dictionary attempt and None on the get attempts. I can't figure out why I'm not able to return the pk for the article in order to finish the code. Also, I've tried to get other data from the Post model, with the same errors. -

Django Social Auth Update First And Last Name in Django App Permanently
I am using django-social-auth to simplify the coded needed to use Auth0 to authenticate for the django application. I want to give my users the functionality to update their first and last names within the django application and have set up an edit profile form to do so. However, after changing their first and last name, once a user logs out and logs back in, their name is re-written so that their first name is their email and they have no last name. I have already tested to make sure the form is working properly (both from the app front end and the database). Is there something I need to configure to prevent social-auth from re-setting the user's name each time they log in? -

Button must have a tooltip in one of template, but not in the others
I include the button for different templates (and different divs). There should be a tooltip in one of these divs, but not in the others. How can I do this? I think I can check the div class in the button (something like {% if div_class=="..."%}), but I do not know how to do this. Is it possible? Maybe I need to check the template name or something else? first.html <div class="single-card__favorite"> {% include 'button.html' %} </div> second.html <div class="card__footer"> {% include 'button.html' %} </div> button.html {% load user_filters %} {% if author|isfavorite:user %}> <button class="button button_style_none" name="favorites"> <span class="icon-favorite icon-favorite_active"></span> </button> <div class="single-card__favorite-tooltip tooltip">Delete from favorites</div> {% else %} <button class="button button_style_none" name="favorites" data-out> <span class="icon-favorite"></span> </button> <div class="single-card__favorite-tooltip tooltip">Add to favorites</div> {% endif %} -
Django fails at properly redirecting from one view to another
I have a search bar on the side of the webpages of the app i'm working on, what i'm trying to do is have my search view take in the user's query, compare it with a list of entries and if what the user typed in matches the title of any of the entries available, search should redirect to another view called title which handles rendering the html file of the entry the user searched for along with matching it with the approparitate URL (i.e if the user searches for the Django entry, title renders HTML file of said entry and assigns it the URL "example.com/Django") The problem lies in the fact that every time i redirect from search to title, title renders the html file reserved for the case in which no entry matches what the user searched for, no matter whether the entry is available or not. It should also be noted that the path for the search view is a mess. if i write the path like that path("<str:search>", views.search, name="search" i get a NoReverseMatch error saying that django was expecting an argument but recieved none, but path("search", views.search, name=search causes the rendered error page to have … -

Rendering part of a form conditionally
I have a form where I need to only take address input if "new-address" is selected. I've been trying to only include this form if the correct radio button is checked, but I'm having trouble getting it to work. If I don't escape the braces, the js breaks, but if I do, it renders the addressform as {% include 'partials/form_fields.html' %} and not as the actual form template. I'm open to django based solutions, but this logic needs to be done without refresh. js var addresslist = document.getElementById("address-list"); var addressform = "\{% include 'partials/form_fields.html' %\}" addresslist.addEventListener("change", function () { var address = document.querySelector('input[name="addresses"]:checked').value if (address == "new-address") { console.log(address) document.getElementById('address-form').innerHTML = addressform; } else { console.log(address) document.getElementById('address-form').innerHTML = ""; } }); form <form method="POST" id="subscription-form" data-secret="{{client_secret}}"> {% csrf_token %} <label class="block uppercase text-gray-600 text-xs font-bold mb-2">Payment Details</label> <div class="form-check my-3 bg-gray-200 p-2 rounded-md"> <input class="form-check-input" type="radio" name="payment-methods" id="add-new-card" value="add-new-card" onclick="addCard()"> <label class="form-check-label" for="add-new-card"> Add new payment method </label> <div id="new-card" style="display: none;"> <label class="block uppercase text-gray-600 text-xs mb-2" for="cardholder-name"> Name on Card </label> <input id="cardholder-name" class="mb-2 border-0 px-3 py-3 placeholder-gray-300 text-gray-600 bg-white rounded text-sm shadow focus:outline-none focus:ring w-full ease-linear transition-all duration-150" value="{{customer.name}}" detype="text"> <!-- placeholder for Elements --> <label class="block … -
Semantic UI active link with django not working properly
Thank you for trying to help. Here's my problem. I'm starting to do a simple blog project with Django and to learn something new for the styling I'm doing it with Semantic UI. In the menu, I tried to do the active links dynamically and did it with 'active link tags' in Django. It's working properly in the 'About' tab, but the 'Home' tab is constantly active. Here's my code in the template. <div class="ui pointing menu"> <a class="item {% active_link 'home' %}" href="{% url 'home' %}"> Home </a> <a class="item {% active_link 'about' %}" href="{% url 'about' %}"> About us </a> </div> Here is how the menu looks like when I'm on 'About' -
Django - Get image link from form and save to database

Apply filtering in Django-admin inline section
I'm stuck in filtering my Django-admin section using NestedTabularInline. Trying to get it right using a custom Modelform. I want to filter the plan method on the selected plan activity parent. 2 problems: The print(filter_id) generates only output when the first relation is stored in the database, which makes sense.
