Django & Ajax - "Like" button, how to make it work for mutliple posts on a page?
There are a lot of similar questions already raised, but so far haven't managed to fix my setup. I successfully created a 'like' button with a counter, but it works only on one post, where there are multiple on one page (while hitting the like button on another post, only the first one gets changed). What should I change in the code, to make it work for all posts? HTML button {% for news in newss %} <div class="col-md-6"> {% csrf_token %} <button class="like-button" value="{{ news.id }}" > Like </button> <span class="" id="like_count">{{ news.news_likes_count }}</span> </div> {% endfor %} AJAX <script> $(document).on('click', '.like-button', function (e) { e.preventDefault(); $.ajax({ type: 'POST', url: '{% url "like" %}', data: { newsid: $('.like-button').val(), csrfmiddlewaretoken: $('input[name=csrfmiddlewaretoken]').val(), action: 'post' }, success: function (json) { document.getElementById("like_count").innerHTML = json['result'] }, error: function(xhr, errmsg, err) { } }); }) </script> views.py @login_required def like(request): if request.POST.get('action') == 'post': result = '' id = int(request.POST.get('newsid')) news = get_object_or_404(News, id=id) if news.news_likes.filter(id=request.user.id).exists(): news.news_likes.remove(request.user) news.news_likes_count -= 1 result = news.news_likes_count news.save() else: news.news_likes.add(request.user) news.news_likes_count += 1 result = news.news_likes_count news.save() return JsonResponse({'result': result,}) urls.py path('like/', views.like, name='like') models.py class News(models.Model): news_title = models.CharField(max_length=100) news_text = models.TextField(max_length=2000) news_author = models.CharField(max_length=150) news_created_date = models.DateTimeField(default=now) … -

Sort django admin column by __str__ method
I have a Folder model and I want to display the columns in the admin page ordered alphabetically following the __str__ method. I looked over several similar questions like this one, this one and also this one, but didn't manage to really understand the answers, or at least enough to adapt them to my problem (even though I've been trying for quite some time). Here is my Folder class, with the str method I want to sort with : class Folder(models.Model): folder_name = models.CharField(max_length=200) parent_folder = models.ForeignKey('self', on_delete=models.CASCADE, blank=True, null=True) def __str__(self): if self.parent_folder: return f'{self.parent_folder}/{self.folder_name}' else: return self.folder_name And my FolderAdmin class : class FolderAdmin(admin.ModelAdmin): ordering = ('str',) #I want it to do like that but don't know how to do it fieldsets = [ (None, {'fields': ['folder_name']}), ('Parent Folder', {'fields': ['parent_folder']}), ] list_display = ('folder_name', '__str__') I feel dumb for not understanding a question already answered multiple times but if you could help me understand it I'd be grateful. Thank you in advance ! -

Whats a good pattern for a web-application for serving files?
I am working on an angular Web-Application where it's possible to view pdf-files in a pdf-viewer in the browser. The Web-Application is also consuming a REST-Service in Django. In the Database the information of the pdf-files is stored. The Web-App is calling the REST-API to check where the files are stored. As I am still in the Proof-Of-Concept Phase of the project, the PDF-Files are currently stored in the assets folder of the angular web, which of course is not what I want in the end. When the Files or the Directories change, the Database should be updated automatically (or via a trigger in the app). I have two questions: Is there an obvious way to serve the files in this combination? i.e. an apache server? I imagine there are built in solutions in dedicated file servers to detect changes of the watched directory. For a partly solution would it be reasonable to write a script on the django site, which does the file-serving, the updating and also providing the REST-API? -
Django: form not showing up in rendered template
I tried to add a page in my admin panel for the user to upload a CSV file. However, the form I passed into the template is not displayed, although I followed this tutorial. https://www.youtube.com/watch?v=BLxCnD5-Uvc&t=340s (From around 14:20 to 17:30) I checked if the context containing the form is correctly passed into the template by passing in a random text, but that random text was displayed in my template and it was just the form that is not being rendered. This is my admin.py: class CsvImportForm(forms.Form): csv_upload = models.FileField() class UserAdmin(BaseUserAdmin): form = UserChangeForm add_form = UserCreationForm list_display = ('email', 'first_name', 'middle_name', 'last_name', 'role', 'subject', 'schedule_uploaded', 'is_admin') list_filter = ('is_admin',) fieldsets = ( (None, {'fields': ('email', 'password', 'first_name', 'middle_name', 'last_name', 'role', 'subject', 'schedule_uploaded')}), ('Permissions', {'fields': ('is_admin',)}) ) add_fieldsets = ( (None, { 'classes': ('wide',), 'fields': ('email', 'password1', 'password2', 'first_name', 'middle_name', 'last_name', 'role', 'subject', 'schedule_uploaded', 'is_admin')} ), ) search_fields = ('email', 'first_name', 'middle_name', 'last_name', 'role', 'subject', 'schedule_uploaded') ordering = ('email', 'first_name', 'middle_name', 'last_name', 'role', 'subject', 'schedule_uploaded') filter_horizontal = () def get_urls(self): urls = super().get_urls() new_urls = [path('csv_upload/', self.csv_upload)] return new_urls + urls def csv_upload(self, request): form = CsvImportForm() context = {"form": form} return render(request, 'admin/csv_upload.html', context) This is my template: {% … -
How to access one Django Project Database from another Django Project?
I am trying to access one Django Project Database value from another Django Project. So far I have tried making REST API on both the applications and it is working somewhat well on the local server. However, I am concerned that when I will be deploying both the projects on the server it will create some lag to access over the API. Moreover, if one server/application is down for maintenance, the other will be inaccessible. Is it possible to directly access the other app database without using API as it will be much more faster and reliable? Thanks. -

Unicode in Content-Disposition in Post-IE11 area
Accoding to this old answer you need to encode a unicode filename like this: from urllib.parse import quote disposition = 'attachment' if as_attachment else 'inline' try: filename.encode('ascii') file_expr = 'filename="{}"'.format(filename) except UnicodeEncodeError: file_expr = "filename*=utf-8''{}".format(quote(filename)) response.headers['Content-Disposition'] = '{}; {}'.format(disposition, file_expr) Just for fun I tried this: response = HttpResponse('abcd') response['Content-Disposition'] = b'attachment; filename="{}"'.format('üöä & €.txt'.encode('utf8')) return response And Chrome, Firefox and Epiphany (WebKit) where able to download the file to üöä & €.txt.

Using Django ORM to sum annotated queries
I am using Django in combination with a TimescaleDB to process energy data from pv installations. Now I would like to calculate, how much energy multiple plants have generated within a given timebucket (usually per day). The plants writing the new values in a table which looks like that: customer datasource value timestamp 1 1 1 01.05.22 10:00 1 1 5 01.05.22 18:00 1 2 3 01.05.22 09:00 1 2 9 01.05.22 17:00 1 1 5 02.05.22 10:00 1 1 12 02.05.22 18:00 1 2 9 02.05.22 09:00 1 2 16 02.05.22 17:00 Now what I would like to have is, get the overal daily gain of values (so, for each day: Last Entry Value - (minus) First Entry Value) for each customer (which means, sum the daily generated energy values from all datasource which belong to the customer). In the above example that would be for customer 1: Day 01.05.22: Daily Gain of Datasource 1: 5 - 1 = 4 Daily Gain of Datasource 2: 9 - 3 = 6 Overall: 4 + 6 = 10 Day 02.05.22: Daily Gain of Datasource 1: 12 - 5 = 7 Daily Gain of Datasource 2: 16 - 9 = 7 Overall: … -

So i want to make models form to upload file mp3. I was copy the code from website, but suddenly it goes error. Here's error message on the website : Forbidden (403) CSRF verification failed. Request aborted. Help Reason given for failure: CSRF token missing or incorrect. In general, this can occur when there is a genuine Cross Site Request Forgery, or when Django's CSRF mechanism has not been used correctly. For POST forms, you need to ensure: Your browser is accepting cookies. The view function passes a request to the template's render method. In the template, there is a {% csrf_token %} template tag inside each POST form that targets an internal URL. If you are not using CsrfViewMiddleware, then you must use csrf_protect on any views that use the csrf_token template tag, as well as those that accept the POST data. The form has a valid CSRF token. After logging in in another browser tab or hitting the back button after a login, you may need to reload the page with the form, because the token is rotated after a login.
