Access image from cloud storage given the name inside of a model in Django-Python
I am in need of ideas/help. I am saving the image from my angular client into a cloud storage bucket and saving the name of the file in a django model in mysql. I am able to access the file if I create an url like the one below on a django template: {% for visitor in visitors%} <img src="https://storage.cloud.google.com/BUCKET_NAME/{{visitor.image_name}}"> {% endfor %} This works because I have added my organization to have permissions in the cloud bucket, so when I am signed in onto Gmail, it will let me output the picture. But once I am signed out, it will not output the picture. And since; this works on a Desktop computer for me, but not on a mobile device. What is another way I can access this picture from my cloud bucket? given my current model. Any help will be much appreciated. -

Was I supposed to be able to create a question on the website using 'runserver'?
I'm following this Django tutorial. So far I haven't had an issue so far, but now I'm not really sure if I understood it correctly. We created a shortcut function to create questions, but I thought that it was meant to be user-side and when I use 'runserver', on the website there's no such option, only the previously created question. This is the code for the function: def create_question(question_text, days): """ Create a question with the given `question_text` and published the given number of `days` offset to now (negative for questions published in the past, positive for questions that have yet to be published). """ time = timezone.now() + datetime.timedelta(days=days) return Question.objects.create(question_text=question_text, pub_date=time) Did I get it wrong? This function is only admin-sided? It's on 'polls/test.py' and it's outside every class. -

Converting a Function to CBV for Django Project
I have created a blog project using a Class Based Viewand now I was trying to add the like button to the posts. So, I want to know how to convert the function used in the project to be included in the Class Based View. My question is how to convert the function used in the tutorial to fit in my project to be included in the Class Based View. (It is a learning process for me to also include Comments.) Here is the models.py class Post(models.Model): liked = models.ManyToManyField(User, default=None, blank=True, related_name='liked') ...................................... @property def num_likes(self): return self.liked.all().count() LIKE_CHOICES = ( ('Like', 'Like'), ('Unlike', 'Unlike') ) class Like(models.Model): user = models.ForeignKey(User, on_delete=models.CASCADE) post = models.ForeignKey(Post, on_delete=models.CASCADE) value = models.CharField(choices=LIKE_CHOICES, default='Like', max_length=10) date_liked = models.DateTimeField(default=timezone.now) def __str__(self): return str(self.post) Here is the views: class PostListView(ListView): model = Post template_name = "blog/post_list.html" # <app>/<model>_<viewtype>.html ordering = ['-date_posted'] context_object_name = 'posts' paginate_by = 1 class UserPostListView(ListView): model = Post template_name = 'blog/user_posts.html' # <app>/<model>_<viewtype>.html context_object_name = 'posts' paginate_by = 5 def get_queryset(self): user = get_object_or_404(User, username=self.kwargs.get('username')) return Post.objects.filter(author=user).order_by('-date_posted') class PostDetailView(DetailView): model = Post template_name = "blog/post_detail.html" # <app>/<model>_<viewtype>.html def get(self, request, *args, **kwargs): res = super().get(request, *args, **kwargs) self.object.incrementViewCount() return res def … -
Django dynamic queryset
I have a view which can receive from none to four different filter lookups. Let's say it starts with Model.objects.all() and then if filter_option is not None and filter_option != '' the idea is to add that filter to the queryset. Making a lot of ifs is a solution but it's really ugly. This is what I'm trying but I'm not getting the expected behavior: class CourseList(ListView): model = Course paginate_by = 10 def get_queryset(self, queryset=None): q = self.request.GET.get('q') sort = self.request.GET.get('sort') level = self.request.GET.get('level') qs = Course.objects.all() if q is not None and q != '': qs.filter(Q(title__icontains=q) | Q(description__icontains=q)) if sort is not None and sort != '': qs.order_by(sort) if level is not None and level != '': sq.filter(level=level) return qs For each "if true" condition I want those options added to the queryset. But instead I'm just getting Course.objects.all() as result all the time. -
Download zip file from http api in react, Receiving error: "Unable to expand file.zip. It is an unsupported format"
Thanks in advance for taking a look. I am working on being able to download a zip file from react through a django api request. I am able to click on my pop up that downloads the zip file, but when I double click on the zip file to open, I get this error: "Unable to expand file_name.zip. It is an unsupported format" My response with the zip file seems to be passing correctly to the front end, so I am thinking it may be something wrong with the react code when making the "blob"? Thanks again. Django code: class DownloadZip(APIView): def post(self, request, format=None): # information to find file to create zip profile_name = request.data["profile"] profile_year = request.data["year"] # file path to create zips from path = str(Path(__file__).parent.resolve()) zip_dir = shutil.make_archive(profile_name + profile_year, "zip", path + "profile_name") s = io.StringIO(zip_dir) response = HttpResponse(s, content_type = "application/zip") zip_name = profile_name + profile_year + ".zip" response["Content-Disposition"] = f"attachment; filename={zip_name}" return response React code: downloadZip = async () => { const params = { profile: this.state.profileName, year: this.state.year, }; axios({ url: `${serverUrl}/download_zip`, method: "post", data: params }).then( (res) => { const url = window.URL.createObjectURL(new Blob([res.data],{type:'application/zip'})); const link = document.createElement('a'); link.href = url; … -
saving images on a local files with heroku
Hello i am new to django and I am almost done with my first web development but I have this Problem that I noticed. images are not getting saved on the File that is set for saving images on my local PC and therefor I was wondering if its a problem on my part or heroku dose not work like the localhost. I would be thankful for some explaining and thanks Here is some codes of my project: Settings.py TEMPLATES = [ { 'BACKEND': 'django.template.backends.django.DjangoTemplates', 'DIRS': [os.path.join(BASE_DIR, 'templates')], .....

How do I update an object that was made with POST in a React front-end... in a Django backend?
I'm trying to follow a tutorial, these are the videos in the series I watched so far: Part 1 Part 2 (Handling Post Requests) Of course you don't want to watch the videos, so here's the project on GitHub: here My method for handling post requests is pretty much the same as his. It looks like this: class CustomForm extends React.Component { handleFormSubmit = async (event, requestType, profileID) => { const postObj = { user_name: event.target.elements.user_name.value, } if (requestType === "post") { await axios.post("http://127.0.0.1:8000/api/create/", postObj) .then(res => { if (res.status === 201) { this.props.history.push(`/`); } }) } else if (requestType === "put") { await axios.put(`http://127.0.0.1:8000/api/${profileID}/update/`, postObj) .then(res => { if (res.status === 200) { this.props.history.push(`/`); } }) } } So I have a question. What if I did it they way he did it, but instead of just posting to the server (posts happen on form submission)... I want to post to the server AND have my backend start asynchronously updating that posted object as soon as it's posted? How would I go about doing that (based off his / my code [kinda identical] ? The closest thing I can think of is using the views.py file to take in …
