How to identify id of object being accessed django
So what I am trying to do in Django is writing a delete function. Basically I have a manytomanyfield set for my Course model where I specify the relationship with the User model which i have called students. students = models.ManyToManyField('User', blank=True, related_name='studies') From looking through django documentation and some other stackoverflow questions, I found that I could use course.students.remove(user). to remove a user object from a specific course. However, what I am having trouble with is understanding how I can find the specific course id at the specific instance. So this is my url. url(r'^courses/(?P\d+)$', CourseDetail.as_view(), name='courses.detail'), I want to find out the current identifier for the course object being accessed so that I can eventually filter through my course objects looking for the specific course in order to remove the student. -
How to preserve position after page reload using infinite scroll in Django
I have implemented infinite scroll for my data objects using jQuery and Waypoints. Works fine but I want to make it more convenient. First of all I`m looking for a way to preserve position after page reload. Also would be nice to add fixed pagination bar with a possibility to dislay your curent page dynamically while scrolling. I have add one, but how to dynamically display your position. Implies, I have 20 objects per page, when scrolling down for 20 next it should automatically switch current page for second one on pagination bar. And vice versa for scrolling up. Another question is when choosing exact page at my current pagination menu it opens separate page with link 'http://127.0.0.1:8000/?page=2' for example, and displays objects only from 41th to 60th. I need it to open exact page but with possibility to scroll up and down for previous and next pages. Which way it`s possible to do this? Here is my code below. models.py from django.core.validators import MinValueValidator, MaxValueValidator from django.db import models class Bancnote(models.Model): type = models.CharField(max_length=11) par = models.PositiveIntegerField() year_from = models.PositiveIntegerField() year_to = models.PositiveIntegerField() size = models.CharField(max_length=7) sign = models.CharField(max_length=20) desc = models.TextField(max_length=200) image = models.ImageField(upload_to='bons_images') def __str__(self): return str(self.par) … -

ImportError: cannot import name '__version__' error while trying to run Django project
I am not sure whether such format of question is valid. Simply I spent three hours trying to google the issue, but I the worst think is that I can't figure out where to look for the root cause of the problem.

Custom template tag don't work as expected (django)
My custom template tag is called change_page and should change page=x in the url without changing anything else in the url. (That means anything in the url, before and behind the ?.

Django model lookup on reverse ManyToMany Field
I am somewhat new to Django and I'm trying to solve what is probably a fairly simple task. I have two models (Destination and Tour).

Django admin CSS randomly gone
I was working on the admin interface of my Django project, trying to get the right fields to show up in the right form, then on one of the reloads the CSS stopped loading, the Chrome inspector tells me the CSS files return a 404 error. I don't know what happened and can't figure it out. It's not a static files issue - the project doesn't use static files at all, and the staticfiles app has been commented out in settings.py (this is not recent, the CSS has been working for weeks without it). Debug is set to True (this also is not recent), however the project isn't served by runserver anyway. I've tried destroying and recreating the virtual machine the project is running on, which means literally everything except the project's own files is 100% fresh. Problem still persists. The question is, what can I do to get CSS working again? -
Django 1.9.13 complains SubfieldBase is deprecated, but I'm not using it. How to resolve?
I am upgrading an old Django project from Django 1.8.3 to the current Django 1.11, but to be cautious, I am upgrading to each major release of Django along the way, so I can find errors & deprecations and fix them before taking the next step. (I haven't touched this code in almost two years, so I'm a little rusty; forgive me if I'm making a simple mistake.) I first upgraded to Django 1.9.13 (the last before 1.10), and when I manage.py runserver, I get this error: /Users/mboszko/.virtualenvs/opticaldev/lib/python2.7/site-packages/django/utils/six.py:808: RemovedInDjango110Warning: SubfieldBase has been deprecated. Use Field.from_db_value instead. return meta(name, bases, d) If I'm reading this error right, the error stems from the custom version of six that Django embeds. I have searched my code, and I don't seem to be using SubfieldBase anywhere in my own code. (I have also googled, with not much success, for this particular error in six.) Is this just a situation where I should upgrade to Django 1.10, and the new version of six in that package will be compatible, or is there something that I need to resolve myself before I upgrade? -
Trigger to send new rows added to database to another database in postgres?
I have 2 databases on 2 different servers (say A & B). I have some crawlers that use API functions to write data to database (A). Some of this data are new and others are just updates to previous rows. If some new rows are added to (A) I want to add id of these new rows to (B). I want this to happen in real time without full scan of (A) iteratively. I want something like a trigger in (A) to send new ids to (B). How should I do write this trigger?(If you think there is a better solution, please help me) -
Django, how to display reply form for comment and what should the views.py look like

Django - working with queryset

The query that I'm using for testing is this: carprice = Price.objects.filter(car__category='1').values('car__name','price','dealer__name').order_by('car__name') The resulting QuerySet looks something like this: <QuerySet [{'car__name': 'Audi Model A', 'price': Decimal('32000.00'), 'dealer__name': 'Dealer A'}, {'car__name': 'Audi Model A', 'price': Decimal('35000.00'), 'dealer__name': 'Dealer B'}, {'car__name': 'Audi Model A', 'price': Decimal('35000.00'), 'dealer__name': 'Dealer C'}, '...(remaining elements truncated)...']> Question 1: Can the query be modified so that the QuerySet does not repeat the car__name every time but instead groups prices and dealers by car__name?

Django rest framework - return objects ordered by callable method result
So basically the title says it all: how can I order the queryset that will be returned on the API by a callable method result that is not stored on the database? This field is dynamic and depends on each user's request, hence it can't be stored anywhere. I tried just using, which is what I want to achieve: queryset = Post.objects.filter('my_filters').order_by('my_method') but it doesn't work since it has to be a column on the database. I also tried: queryset = sorted(Post.objects.filter('my_filters'), key=lambda x: x.my_method()) But it throws the "AttributeError: 'list' object has no attribute 'model'" error. How can I sort the results of the queryset according to a method then? Any ideas? I will also need to limit the number of responses to the top results calculated this way. Thanks! -

Django subdomain configuration for third party application integration

Saving a Date in a Coisefield - Django?
so what I'm trying to build is basically a calendar. For this, a user has to choose a beginning date and time for an event as well as an end time. Everything then has to be stored - of course - in the database. I want to realize that by using a ChoiseField (unless there is a better solution). How would it be possible to generate all the dates of the month in a coisefield since some months are 30 days others have a different length etc.? Same with the hours of a day? I cant seem to come up with a working approach? How would one approach this problem? suggestions? -
Django ORM: building models of dialog where one member has to be emphasized
It's not so obvious to me how to organise a dialog with django ORM. Especially if I need to know who first started a dialog(because he is a buyer and person who answers is a sales, and we need to know exactly who sales a thing ). So, I see two solutions. First one looks like this: class Dialog(models.Model): buyer = models.ForeignKey(UserProfile, related_name='buyer_reverse') sales = models.ForeignKey(UserProfile, related_name='sales_reverse') But queryset could bring some trouble. As I suppose, query would look something like: dialogs = Dialog.objects.filter(Q(buyer=request.user.userprofile) | Q(sales=request.user.userprofile)) Another solution I guess is: class Dialog(models.Model): members = models.ManyToManyField(UserProfile) sales = models.ForeignKey(UserProfile, related_name='sales_reverse') What is the best solution except there are both wrong? -
ImageField instance doesn't have save method in Django shell. But it does when I'm running the actual server
I'm a Django novice studying with Django By Example by Antonio Mele. I stuck up at chapter 5 where I needed to resort to ImageField's save method. Here is a part of the code edited by me. from urllib import request from django import forms from django.core.files.base import ContentFile from images.forms import ImageCreateForm from images.models import Image class ImageCreateForm(forms.ModelForm): def save(self): img = super(ImageCreateForm, self).save(commit=False) # ... response = request.urlopen(image_url) img.image.save(image_name, ContentFile(response.read(), save=False) # ... class Meta: model = Image # ... And the Image model looks like this. from django.db import models class Image(models.Model): # .... image = models.ImageField(upload_to='images/%Y/%m/%d') # .... So img in save method of ImageCreateForm is an instance of Image and img.image is an instance of models.ImageField, right? I looked it up on the official django document and even inspected django sourcecode but I couldn't find save method. I tried this on django shell but it gave me only an error. It seems like models.ImageField type doesn't have save method. But, somehow when I actually run the server this raises no errors and gets to have save method. How can this be possible? You can find the whole source code here. https://github.com/guinslym/django-by-example-book/tree/master/Django_By_Example_Code/Chapter%205/bookmarks -
How to render a html string in javascript?

I conver the markdown text to html text and return a response to ajax, then I insert the html text to page, but the html text can't be rendered.
