How to upload a Excel sheet in Angular and receive it in Django
I'm new to Angular and Django. My requirement is to build a webpage, from which user can upload a excel sheet. I need to receive this excel sheet in back-end (Django) and perform operations on that file. I checked various examples but somehow I couldn't do it. html.ts .. </form> <input type="file" (change)="selectExcel($event)"> <button type="button" (click)="uploadExcel()">Upload Excel</button> </form> Component.ts selectExcel(event){ this.selFile=event.target.files[0] } uploadExcel(){ console.log(this.selFile) const fd = new FormData(); fd.append('file', this.selFile,this.selFile.name); console.log(fd) this.service.fileUpload(fd) .subscribe(res=>{ console.log(res) }) } service.ts fileUpload(f){ return this.http.post(this.API+'fileupload/',JSON.stringify(f)) } } I'm really not sure how to receive the file in Django..

Django regex works only if the caret is typed into the address abr
I'll preface this by saying that I'm a designer trying to learn to code. Now that that's out of the way… My urls.py looks like this: urlpatterns = [ path(r'^admin/', admin.site.urls), ] but I get a 404 that says: Django tried these URL patterns, in this order: ^admin The current path, admin/, didn't match any of these. However, if I type the URL as http://127.0.0.1:8000/^admin/, which sanitizes to http://127.0.0.1:8000/%5Eadmin/, I can see the admin dashboard. Why is the regular expression not working here? Does something need to be imported? -

For example #include<stdio.h> int main(){ int a, b; scanf("%d %d", &a, &b); printf("%d", a-b); return 0; } ------ >>>>> this code will be change below one int main(){ int a, b; scanf("%d %d", &a, &b); printf("%d", a-b); return 0; } then aggregate Model.objects.all().annotate(code_len=Length('uncomment_code')).aggregate(shortest_code_len=Min('code_len'))['shortest_code_len'] this is not work, i know property can not use in queryset. do you have any other idea? i can't add model field for uncomment_code. -

Django FORCE_SCRIPT_NAME in settings

A single url for many urls with common ending
I want to submit a form from any page. For that I have kept the form in base.html. But when a user submits the form, it redirects to a page with different url from different page. For an example, when user is on localhost:8000/example1/page1/ and click submit button it takes to the url localhost:8000/example1/page1/submit.. when user is on localhost:8000/example2/page2/something/else/ and click submit button it takes to the localhost:8000/example2/page2/something/else/submit.. One solution that I can think of is to have all these urls in my urls.py file to ensure smooth routing. But I feel that's not the right way to do. Second solution I think of is to put a button to redirect to the form on the base html so that it appears on all page and when a user has to fill the form he can click it and go. But I want the form to appear on every page on the sidebar. Any suggestion would be highly helpful. Thanks. -

Why is Django FieldFIle readline() returning the hex version of a text file?
Having an odd problem. I have a Django app that opens a file (represented as a Django FieldFile) and reads each row using readline() as below: with file.open(mode='r') as f: row = f.readline() # do something with row... The file is text, utf-8 encoded and lines are terminated with \r\n. The problem is each row is being read as the hex representation of the string, so instead of "Hello" I get "48656c6c6f". A few stranger things: It previously worked properly, but at some point an update has broken it (I've tried rolling back to previous commits and it is still wonky, so possibly a dependency has updated and not something from my requirements.txt). Missed it in my testing because it is in a very rarely used part of the app. If I read the same file using readlines() instead of readline() I see the correct string representation of the file wrapped in [b'...'] The file reads normally if I do it using straight Python open() and readline() from an interpreter Forcing text mode with mode='rt' doesn't change the behaviour, neither does mode='rb' The file is stored in a Minio bucket, so the defaut storage is storages.backends.s3boto3.S3Boto3Storage from django-storages and not … -

FileNotFoundError when users try to upload a photo

Two slugs in url
I want to have a url pattern that takes 2 slugs. I'm trying to make it look like http://127.0.0.1:8000/category/model but I'm having difficulties understanding how to do this. Below is what I have so far: models.py def model_detail_view(request, category_slug, model_slug): model = Model.objects.get( category__slug=category_slug, model_slug=model_slug) context = { "model": model, } return render(request=request, template_name='main/model_detail.html', context=context) urls.py path("<str:category_slug>/<str:model_slug>/", views.model_detail_view, name="model_detail_view"), models.py class Category(models.Model): title = models.CharField(max_length=50) featured_image = models.ImageField(upload_to="categories") category_slug = AutoSlugField(null=True, default=None, unique=True, populate_from='title') class Meta: verbose_name_plural = "Categories" def __str__(self): return self.title class Model(models.Model): title = models.CharField(max_length=80) category = models.ManyToManyField(Category) featured_image = models.ImageField(upload_to=image_dir) model_slug = AutoSlugField(null=True, default=None, unique=True, populate_from='title') class Meta: verbose_name_plural = "Models" def __str__(self): return self.title -
How to implement comments in Django attached to a user
I am attempting to add comments to posts (in this site posts are called beets) and would like each comment to be from a user and attached to that user. A user should have a list of comments they have made. The post the comment is on should show the comments as well. I have gotten as far as I can add comments through the admin page, but I can't add them through the form on the site. I do not receive an error message, but the comments do not show up in the admin or the site. Also, even though the comments post from the admin screen, they do not show up on the site. Models.py class Beets(models.Model): content = models.TextField(max_length=240) date_posted = models.DateTimeField(default=timezone.now) author = models.ForeignKey(User, on_delete=models.CASCADE) likes = models.ManyToManyField(User, related_name='likes') def __str__(self): return f"Beet by {self.author}" def get_absolute_url(self): return reverse('beets:beets-detail', kwargs={'pk': self.pk}) @property def total_likes(self): """ Likes for the beet :return: Integer: Likes for the company """ return self.likes.count() def likes_as_flat_user_id_list(self): return self.likes.values_list('id', flat=True) class Comment(models.Model): beet = models.ForeignKey( Beets, on_delete=models.CASCADE, related_name='comments') author = models.ForeignKey(User, on_delete=models.CASCADE) content = models.TextField(max_length=240) date_posted = models.DateTimeField(default=timezone.now) def __str__(self): return self.content views.py - just the comment part def add_comment_to_beet(request, id): if request.method … -
Django not saving timezone info. How to store this correctly
I've got this code in an ajax view: now = pytz.timezone("America/Guayaquil").localize(datetime.now()) print("HOUR: %s" % now.hour) new_timer = WorkTime.objects.create(inicio=now) print("new_timer.id: %s" % new_timer.id) print("new_timer.hour %s" % new_timer.inicio.hour) it prints this: HOUR: 18 new_timer.id: 16 new_timer.hour 18 "inicio" is a DateTimeField. Then I access the same object from a regular view to render an html, this is the code: last_timer = TiempoEmpresarial.objects.filter(final__isnull=True).last() print("Timer object:") print(last_timer.id) # is it the same obj? print(last_timer.inicio.hour) it prints this: Timer object: 16 23 It is the same object, id=16. But it has a different hour. Why?
