Aborting long running request in Django
I want to abort a request to an API which takes longer than 5 seconds. I know the client-side code can have a timeout of 5 seconds and that will ensure it doesn't wait any longer than that to get a response, but the Django server would still be processing the request even though the client won't be receiving it at the end. As far as I know, even if I configure this on nginx or gunicorn, those will still act as clients for the Django server app and the same problem will occur - that nginx will not wait for more than 5 seconds, but Django will continue processing the request. Is there any way I can somehow abort this request processing in Django (application server code level) itself? -
css script working but js script not working in Django
My index.css script located at Project/static/css/index.css is working fine and effect is seen in index.html page. But window alert from index.js script is not seen.

Safest and driest way to filter query_set depending on some user info
I have a Post model with a boolean field, is_draft. If the user is logged and is member of the staff, then I want to displays all posts; otherwise, only the posts for which is_draft is false. My first thought was to use a custom model manager and use request.user as following: class PostManager(models.Manager): def get_queryset(self): if request.user and request.user.is_staff: return super().get_queryset() else: return super().get_queryset().filter(is_draft=False) but request is not available in the model. I saw some people use a middleware to access the user in the model. It seems to me the safest way to address my need (ie it's done once, in the custom manager; people modifying the views.py don't have to bother, no risk of forgetting it) but this solution seems controversial. I have of course the possibility to add some logic in the view, but I feel this is not DRY (as I query Post many times) nor safe (risk somebody forgets it at some point). According to you, what would be the cleanest and safest way to address this need? PS: I've found a similar question for which a solution was proposed for Class-based views, but my views are function-based. Thanks a lot! -

Django Jinja - If an object in all objects has attribute run html

Let's say I have this model: from django.db import models class Section(models.Model): name = models.CharField(max_length=20) display = models.BooleanField(default=True) and I create 2 objects with different names and 2 different display variables: >>> s1.display True >>> s2.display False Here I have some HTML code with Jinja templating for this code to display, if these objects even exist: <!-- In Views, Section.objects.all() is 'sections' --> {% if sections %} <div class="all-sections"> <h2 class="title">Explore</h2> {% for section in sections %} <div class="section"> <p class="section-title">{{ section.name }}</p> </div> {% endfor %} </div> {% endif %} Now I make both of them false: >>> s1.display = False >>> s1.save() Now, if ALL OF THEM HAVE DISPLAY FALSE I don't want the entire section to be there, the same as if there weren't any in that list at all. I've thought about doing a for loop and iterating through each one, but then that would just repeat the all of the HTML code for each one that did have display on. <!-- Wouldn't Work Example --> {% if sections %} {% for section in sections %} {% if section.display %} <div class="all-sections"> … -
Django Update view saving but not updating
I have made a working form to post reviews for restaurants. When user is logged in he can see displayed under his post the edit button. When I use the Updateview however, it doesn't edit, but instead creates a new line in which the new review appears (and that new line doesn't appear then on my webpage). Here is the model: class UserReview(models.Model): # Defining the possible grades Grade_1 = 1 Grade_2 = 2 Grade_3 = 3 Grade_4 = 4 Grade_5 = 5 # All those grades will sit under Review_Grade to appear in choices Review_Grade = ( (1, '1 - Not satisfied'), (2, '2 - Almost satisfied'), (3, '3 - Satisfied'), (4, '4 - Very satisfied'), (5, '5 - Exceptionally satisfied') ) restaurant = models.ForeignKey(Restaurant, on_delete=models.CASCADE) user_review_grade = models.IntegerField(default=None, choices=Review_Grade) # default=None pour eviter d'avoir un bouton vide sur ma template user_review_comment = models.CharField(max_length=1500) posted_by = models.ForeignKey(User, on_delete=models.DO_NOTHING) def get_absolute_url(self): return reverse('restaurants:reviews', args=[self.id]) def get_edit_url(self): return reverse('restaurants:edit-review', args=(self.id,)) Here is the update form (similar as review form): class EditReviewForm(forms.ModelForm): class Meta: model = UserReview fields = [ 'restaurant', 'user_review_grade', 'user_review_comment' ] widgets = { 'restaurant': forms.HiddenInput, 'user_review_grade': forms.RadioSelect, 'user_review_comment': forms.Textarea } labels = { 'user_review_grade': 'Chose a satisfaction level:', … -
Use Matplotlib on django site
I am thinking of starting a new django project for plotting stock prices and displaying them onto the site. I know matplotlib pretty well and was wondering if I could plot the chart and somehow push it to the site with the usual matplotlib features like zoom etc. I have seen this done where that images are pushed but I am wondering if I could push the chart with its functionality provided by matplotlib and I can't seem to find an answer anywhere so maybe it isn't possible? -

Django get values for Max of grouped data
After many trials and errors and checking similar questions, I think it worth asking it with all the details. Here's a simple model. Let's say we have a Book model and a Reserve model that holds reservation data for each Book. class Book(models.Model): title = models.CharField( 'Book Title', max_length=50 ) name = models.CharField( max_length=250 ) class Reserve(models.Model): book = models.ForeignKey( Book, on_delete=models.CASCADE ) reserve_date = models.DateTimeField() status = models.CharField( 'Reservation Status', max_length=5, choices=[ ('R', 'Reserved'), ('F', 'Free') ] ) I added a book and two reservation records to the model: from django.utils import timezone book_inst = Book(title='Book1') book_inst.save() reserve_inst = Reserve(book=book_inst, reserve_date=timezone.now(), status='R') reserve_inst.save() reserve_inst = Reserve(book=book_inst, reserve_date=timezone.now(), status='F') reserve_inst.save() My goal is to get data for the last reservation for each book. Based on other questions, I get it to this point: from django.db.models import F, Q, Max reserve_qs = Reserve.objects.filter( book__title='Book1' ).values( 'book__title' ) reserve_qs now has the last action for each Book, but when I add .value() it ignores the grouping and returns all the records. I also tried filtering with F: Reserve.objects.filter( book__title='Book1' ).values( 'book__title' ).annotate( last_action=Max('reserve_date') ).values( ).filter( reserve_date=F('last_action') ) I'm using Django 3 and SQLite. -

Reuse django urls patterns and views
I have a usecase where I would like to reuse a bunch of existing views and url patterns. Current situation is a product with about 20 views for it: urlpatterns = [ # product url(r'^product/(?P<pid>\d+)$', views.view_product, name='view_product'), url(r'^product/(?P<pid>\d+)/something$', views.view_something, name='view_something'), url(r'^product/(?P<pid>\d+)/morethings', views.view_morethings, name='view_morethings'), url(r'^product/(?P<pid>\d+)/deeper/things$', views.view_deeper_things, name='view_deeper_things'), ... etc. So I can browse to the following urls: https://host/product/1 https://host/product/1/something https://host/product/1/morethings https://host/product/1/deeper/things In the new situation I want to add additional ways to browse to the products, i.e. product name or some key valuepair. i.e. https://host/product/name/product1 https://host/product/name/product1/something https://host/product/name/product1/morethings https://host/product/name/product1/deeper/things and https://host/product/meta/property1/value1 https://host/product/meta/property1/value1/something https://host/product/meta/property1/value1/morethings https://host/product/meta/property1/value1/deeper/things where I use a database query in the view to find the product by name, or by the specified property+value. How can I reuse patterns and views to avoid having 20 new views and patterns for each way of identifying a product? I could just list all the (20x3) possible patterns and add 20 more for each new way of identifying products. url(r'^product/(?P<pid>\d+)/something$', views.view_something, name='view_something'), url(r'^product/(?P<pid>\d+)/morethings', views.view_morethings, name='view_morethings'), url(r'^product/(?P<pid>\d+)/deeper/things$', views.view_deeper_things, name='view_deeper_things'), url(r'^product/name/<str:name>/something$', views.view_something_name, name='view_something_name'), url(r'^product/name/<str:name>/morethings', views.view_morethings_name, name='view_morethings_name'), url(r'^product/name/<str:name>/deeper/things$', views.view_deeper_things_name, name='view_deeper_things_name'), url(r'^product/meta/key/<str:name>/<str:name>/something$', views.view_something_meta, name='view_something_meta'), url(r'^product/meta/key/<str:name>/<str:name>/morethings', views.view_morethings_meta, name='view_morethings_meta'), url(r'^product/meta/key/<str:name>/<str:name>/deeper/things$', views.view_deeper_things_meta, name='view_deeper_things_meta'), I know I could do: urlpatterns = [ # product url(r'^product/(?P<pid>\d+)$', views.view_product, name='view_product'), url(r'^product/name/<str:name>$', views.view_product, name='view_product_by_name'), And have default … -
Django Template `With` Operator complex boolean assignment
I am creating a Django template that has columns only visible to admins. Currently I am using a template tag has_group that works well. I have to include some logic for superusers. {% if request.user|has_group:"Admins" or request.user.is_superuser %} <th class="detail_btn_col" scope="col">Detail</th> {% endif %} ... Similar code for the <td> But it's making a query for every row of a table. Not terrible but I would like to just set the value once at the start of the template. I saw that I could assign a variable using with and that would accomplish what I want. {% with has_admin_view=request.user|has_group:"Admins" or request.user.is_superuser %} Does not work. {% with has_admin_view=request.user|has_group:"Admins" %} The above works, but superusers aren't included.

I am trying to make my Django based API return an HTML snippet as a string. I am retrieving the HTML snippet through a BeautifulSoup bs4 element. To convert it into a string, I am simply using the str() operation as follows: test['key'] = str(bs4_element) When I retrieve this value from an API call, I get the HTML code, however, with backslash characters inserted throughout to escape special characters, somewhat like this: "key": "<div class=\"hackdown\"><style id=\"MathJax_SVG_styles\">... I want to render this retrieved HTML in a browser, however, the introduced backslash characters are not letting me do the same. How do I convert the bs4 element such that the above is prevented? -

Django conditional for rendering template
I am new to django and am trying to only render text which does not have the word 'After' or 'Before' in it. However this didnt break anything but it didnt actually remove those values? I looked at using a regex but this really isnt recommended for django templates. {% if "After" not in window.name or "Before" not in window.name %} {{window.event_id}}-{{window.name}} {% endif %} The codebase I am working on makes it almost impossible to remove these values in the models before you get to the template... I can only apologise for maintaining and putting up with this! -

Django Rest Framework, Why does separate serialization class for Image fields is been required?
When serializing a model that contain image field, separate serialization class was been required. Why can't we serialize the model completely in single class ? Serializer.py class ProfileSerializer(serializers.ModelSerializer): user = serializers.StringRelatedField(read_only=True) avatar = serializers.ImageField(read_only=True) class Meta: model = Profile fields = '__all__' class AvatarSerializer(serializers.ModelSerializer): class Meta: model = Profile fields =('avatar',) models.py class Profile(models.Model): user = models.OneToOneField(User,on_delete=models.CASCADE) bio = models.CharField(max_length=100,blank=True) avatar = models.ImageField(null=True,blank=True) def __str__(self): return self.user.username I am following a tutorial in Udemy GitLink : https://github.com/pymike00/The-Complete-Guide-To-DRF-and-VueJS/tree/master/05-DRF-LEVEL-THREE/profilesapi/profiles/api -
CSS loaded but not takes effect on the display
I always get stuck at CSS. I have a table, which works perfectly fine on large screens, and for mobile devices I want the table to be in a card format. I got an idea of creating another div and made the UI for mobile devices as well. And Using CSS, I tried... resp.css .immobile{ display: none; } .immonitor{ display: block; } @media screen and (max-width: 764px){ .immonitor{ display: none; } .immobile{ display: block; } } List.html <tbody> {% for order in order_list %} <div class="immonitor"> <tr> <td>{{ order.id }}</td> <td>{{order.client_name}}</td> <td>{{order.event_name}}</td> <td>{{order.event_date}}</td> <td>{{order.location}}</td> <td><a href="{% url 'order_detail' order.id %}">View</a></td> </tr> </div> <div class="immobile"> <tr> <td> <div> {{order.client_name}} <br> <h3>{{ order.id }}</h3> </div> <div class="pull-right"> {{order.event_name}}<br> {{order.event_date}}<br> {{order.location}}<br> </div> </td> </tr> </div> {% endfor %} </tbody> Now, the CSS doesn't have any effect on the table, it displays both card and table. And the CSS is perfectly loaded.
