Losing data when overriding post method in UpdateView
I wanted to use the same UpdateView with two different templates for 2 separate tasks: Update couple of CharFields Delete instances of related model I pass it different templates in urls.py and override post method like this: def post(self, request, *args, **kwargs): self.object = self.get_object() uploads = Upload.objects.filter(press=self.object) marked_uploads = request.POST.getlist('marked_upload', None) if marked_uploads is not None: for upload_id in marked_uploads: upload = uploads.get(id=upload_id) upload.file.delete(save=True) upload.delete() return super(PressUpdateView, self).post(request, *args, **kwargs) The problem is this: because i don't render CharFields in second template every time i call POST function from my second template, the values in them get erased. How do i correctly override post method so it doesn't happen. PS I know i can simply add <div style="display:none;">{{ form.as_p }}</div> to the form in my second template, but i want to know how to do it in post. -
My live Django website works fine, but my local repo is broken
DM Why does my working website not work from local clone? 0 Daniel Mark · Lecture 56 · 7 minutes ago Hi there, So I have my website running and am generally happy with it. I want to do some updates (add commenting to my blog app and also fix the link from main page to blog). However the website pulled from git does not work locally (error messages at bottom of message). I have had this problem since deleting some image files from the local media (these were my dummy images "uploaded" via the admin page) I have checked using git push from the website and git pull locally (and even with a fresh git clone locally to another folder). The live website on the server is running the latest code (I restarted nginx and gunicorn and even the whole server using sudo reboot). I tried python manage.py flush to blitz the local database, but I cannot recreate one locally. I created a new directory on my local machine and did a git clone, made a virtual env and did a pip install of my requirements. So my question is why is this happening? I don't want to start … -

Design Patterns for Integrating External Data with Django's Database-Backed Models
I'm building a Django web application that maintains both relational data in a MySQL database as well as loosely coupled (by reference ID) full-text data in ElasticSearch (for optimized search). When a new object is created, I leverage Django signals + Celery tasks to asynchronously index the full-text data into Elasticsearch via elasticsearch-py, which works nicely. I had originally started with more tightly-coupled approaches (haystack and django-elasticsearch-py), but I quickly realized that I lost flexibility and decided to de-couple a bit. Well, now I've come full circle as I begin to develop my views/templates (where I largely leverage Model Querysets and the like) and I'm faced with decisions on how to best "fold-in" my loosely-coupled external data. For example, if my homepage by default displays a list of the 50 most recent objects, but then a user conducts a full-text search, how do I best replace the objects (via Ajax) on the page with the ES search result while also linking corresponding database data? And then revert to the Model Queryset data when a filter is pressed and the search is cleared? In other words, what are best practice implementations and design patterns for integrating external data with Django ORM/database-backed … -
Django should I use select_for_update in my view?
Imagine these two cases: First case A website where users can rent cars with each other, so the view that handle the reservation should be something like this: def reservations(request, id): deal = Deal.objects.filter(id=id, available=True) # if not exist return error ... if request.method == 'POST': form = ReservationDealForm(request.POST) if form.is_valid(): reservation = ReservationDeal() with transaction.atomic(): reservation.check_in = form.cleaned_data['check_in'] reservation.check_out = form.cleaned_data['check_out'] # ... reservation.deal = deal[0] reservation.save() deal.update(available=False) # We make the deal not available return redirect('index') Second case An e-commerce website with the view that handle the add to cart feature should be something like this: def add_to_cart(request, id): # ... quantity_request = form.cleaned_data.get('quantity') item = Item.objects.filter(id=id) with transaction.atomic(): # decrease the stock item.stock -= F('stock') - quantity_request item.save() # create an order item for the user or if # he has an order item we update only the quantity order_item = OrderItem.objects.create(user=request.user, item=item, quantity=quantity_request) # ... My questions are: For the first case, what happens if two people in the website click "reserve car" simultaneously for an available car ? It could happen that both requests are valid ? the transaction.atomic guarantee that this cannot happen or should I use select_for_update ? For the second case same … -
Having trouble extending UserDetailSerialzer in django-rest-auth

Django Pagination - how to reduce number of displayed links?
How to display this << 1 2 3 4... 11 12 >> instead of this << 1 2 3 4 5 6 7 8 9 10 11 12>> in my site on Django using pagination ? Thank you in advance !!!

Django default entries on model creation

Insert String Into Django URL in JQuery Load
I'm new to JQuery, Django and web development in general. I'm trying to figure out how to insert a string into the URL in the JQuery load function based on HTML data, but I'm getting reverse URL errors. I have view that returns a rendered HTML table from a file given a search query: urls.py urlpatterns = [ ... path('database/<search>', views.db_search, name='db_search'), ... ] views.py def db_search(request, search): return render(request, 'app/Content/database.htm', {'context': context}) This works fine when I hard-code the search string in JQuery as: $(".filterBtn").click(function(){ $("#mainpanel").load("{% url 'db_search' 'str_param' %}"); }); The problem is that there are multiple filter buttons which are dynamically generated by Django based on the state of the database. I don't want to hard-code the search parameters (nor should I). What I want to do is something like: $(".filterBtn").click(function(){ $("#mainpanel").load("{% url 'db_search' this.innerText %}"); }); but Django throws reverse URL errors because "this.innerText" isn't defined. Reverse for 'db_search' with arguments '('',)' not found. 1 pattern(s) tried: ['database/(?P[^/]+)$'] Am I missing something? It seems like this should be pretty straightforward. -

How to manage version controlled Django migrations as a team?
We're a small team of developers working on a version-controlled Django 3 project. We are worried about utilizing migrations and the possibility of overwriting one another's migration files.

But its showing duplicates of that one element whenever i am trying to click "prev" or "next" or grabbing by "Cursor" I got idea from this link. Picture in which my product is shown in the Swiper div: HTML CODE in Django template: <!-- products --> <div class="container my-4 bg-white border border-light-dark flex"> <div class="lunchbox"> <!-- slider main container --> <div id="swiper1" class="swiper-container"> <!-- additional required wrapper --> <div class="swiper-wrapper"> <!-- slides --> {% for product in products %} <div class="swiper-slide"> <div class="product"> <img class="photograph" src="/media/product_images/{{product.product_code}}.jpg" alt=""> <h2 class="product__name">{{product.name}}</h2> <p class="product__description"><span class="font-weight-normal">৳</span>{{product.product_price}}</p> </div> </div> {% endfor %} </div> <!-- pagination --> <div class="swiper-pagination"></div> </div> <!-- navigation buttons --> <div id="js-prev1" class="swiper-button-prev btn-edit" style="top:35%;"></div> <div id="js-next1" class="swiper-button-next btn-edit" style="top:35%;"></div> </div> </div> JavaScript CODE: (function() { 'use strict'; const mySwiper = new Swiper ('#swiper1', { loop: true, slidesPerView: 'auto', centeredSlides: true, a11y: … -
Django unit tests are returning a strange format where strings are being returned in the format [33 chars] of [num chars]
I am currently building a django-rest-framework API and the unit tests seem to be mostly working but there seems to be a problem with how strings are being handled. So for example I have a test for updating users and it is failing with AssertionError: {'pk': 3, 'username': 'new_user', 'email': [33 chars]: ''} != {'username': 'new_user', 'email': 'new_user[20 chars]': 3} I haven't run into this before and I'm not sure why it is behaving like this. My test settings are: if 'test' in sys.argv in sys.argv: DATABASES = { 'default': { 'ENGINE': 'django.db.backends.sqlite3', 'NAME': ':memory:', 'HOST': '', 'PORT': '', 'USER': '', 'PASSWORD': '', } } Any ideas on why this is happening?
