Django admin script not installed to PATH
I'm on a new computer, and have to install Django again, so I typed the pip install Django command in my VSCode terminal to install it. However, after it downloads, I get this message: WARNING: The script django-admin.exe is installed in 'C:\Users\Xiaow\AppData\Roaming\Python\Python39\Scripts' which is not on PATH. Consider adding this directory to PATH or, if you prefer to suppress this warning, use --no-warn-script-location. Because of this, I can't start any new projects. How would I install this script to PATH? Is there a command I have to do or something? There also seems to be a .vscode folder in 'C:\Users\Xiaow' but I don't know if this is what is making Django not install the admin script to PATH. Everything else works, like I can go to my existing projects (copied over from my old computer) and runserver, and can access all the databases. However, it's just this admin script that is causing problems. I also tried uninstalling and reinstalling Django to no avail.

sending array data with multipart/form-data post request in Axios vue.js
I'm sending a post request from vue.js project using Axios and it contains a file upload, which requires me to use FormData, I found a nice answer that helped me with FormData: const getFormData = object => Object.keys(object).reduce((formData, key) => { formData.append(key, object[key]); return formData; }, new FormData()); and for the headers: headers: { 'Content-Type': 'multipart/form-data'}. The POST call looks like this: axios.post("http://127.0.0.1:8000/api/document/", getFormData(this.documentData), { headers: { 'Content-Type': 'multipart/form-data' } }) .then(response => { console.log("Successfully uploaded: ", response.data) }) .catch(err => { console.log("error occured: ", err) }) This is the data I'm sending: documentData: { name: '', file: '', version: '', company: '', author: '', category: [] } When sending the data with single category id, it works fine, but when I send multiple category ids the following error shows: "category": [ "Incorrect type. Expected pk value, received str." ] How can I solve this problem? -

Is it possible to convert an output image url from django backend back to an image file for upload/reupload?
I have an application preview and a console down below Edit Existing Post Instance The first 2 console logs are images of an existing django post instance that are about to be modified in a form of a URL The third console log is an image file when I added a third image with a file input. e.target.files[0] The behavior that I put in the django rest api for updating existing files in a nested relation is to flush out all images and reupload images in whatever it is in the current edit images preview. The question is that is it possible to convert the first two console logs in a form of a third console log for image reupload that will go through axios? -

So this is part of my models in django : class Dealers(models.Model): id = models.AutoField(primary_key=True) user = models.ForeignKey(User,on_delete=models.CASCADE) language_id = models.ForeignKey(Languages,on_delete=models.CASCADE) shift_id = models.ForeignKey(Shifts,on_delete=models.CASCADE) create_at = models.DateTimeField(auto_now_add=True) update_at = models.DateTimeField(auto_now_add=True) #profile_pic = models.ImageField() def __unicode__(self): return self.user class ExtraShifts(models.Model): id = models.AutoField(primary_key=True) title = models.CharField(max_length=100) slug = models.SlugField() shift_id = models.ForeignKey(Shifts,on_delete=models.CASCADE) language_id = models.ForeignKey(Languages,on_delete=models.CASCADE) ExtraShift_Date = models.DateField() # which day ? thay need people to take an extra Time_List=(('now','NOW'),('10','10am to 6pm'),('6','6pm to 2am'),('2','2am to 10am')) ExtraShift_Time = models.CharField(choices=Time_List,max_length=50) # what time ? thay need people to take an extra create_at = models.DateTimeField(auto_now_add=True) # when this extra created update_at = models.DateTimeField(auto_now_add=True) # when this extra updated priority_list=(("Normal","Normal"),("Urgent","Urgent")) priority = models.CharField(choices=priority_list,default='Normal',max_length=12) quantity = models.IntegerField(default=1) def __str__(self): return self.title class ExtraShiftsOrder(models.Model): id = models.AutoField(primary_key=True) shift = models.ForeignKey(ExtraShifts,on_delete=CASCADE) dealer = models.ForeignKey(Dealers,on_delete=models.CASCADE,null=True) create_at = models.DateTimeField(auto_now_add=True) # when this extra was take it ordered = models.BooleanField(default=False) def __int__(self): return self.id I wanna pass some rolls to the user can take extra and then send it to APIVIEW: for … -
Immediately sending messages using Django Channels
I have a long-running operation that is kicked off by a message from a websocket and I would like my server to send a confirmation to the client with when the operation was started and when it was ended. This is essentially the same as this question but there was no useful answer. I tried await self.send(data, immediately=True) but got an error because it seems immediately is either no longer supported or doesn't work in the async version or something. I really do not want to screw around with setting up channel layers and Redis and having yet another thing to configure that will inevitably break, or worse, have to set up Celery in WSL and deal with all my testing happening in a separate VM. If this isn't possible with just Channels, I am perfectly happy with that so no need to explain how to set it up using a third-party library (if you think others might find it useful, by all means go ahead). -
Use Django REST API and Django Templating
I'm just starting to use Django for my backend services, but I'm a bit confused about the usage of Django REST framework, see I'm building an iOS app as a front-end, to the best of my knowledge Django REST is the best library to perform my backend tasks, however, I would eventually like to build a regular web front-end. I've seen tutorials on Django and Django REST, and they never talk about using both. My question is how to use Django REST to feed the iOS App, and be able to use Django's templating engine for a web front-end using the DRY principle. I did read on the Django REST framework's website, that you can use class based views with the framework, so can I use this same class to feed by web front-end and my ios app efficiently? class SnippetDetail(APIView): def get_object(self, pk): try: return Snippet.objects.get(pk=pk) except Snippet.DoesNotExist: raise Http404 -
How to create logic for users to follow and unfollow in twitter clone
hy, I'm creating a twitter clone using django. I have a problem creating the follow and unfollow button.First, I want the unfollow button to show if the current user is already following a particular user else the follow button should show. Secondly, how can I check if the logged in user is following a particular user. Models.py class Profile(models.Model): user = models.OneToOneField(User,on_delete=models.CASCADE) bio = models.TextField(null=True,blank=True) profile_pic = models.ImageField(default='default.png',upload_to="images/profile/") following = models.ManyToManyField("self",symmetrical = False,blank=True) followers = models.ManyToManyField('self',symmetrical = False,blank=True,related_name='followers_profile_test') def __str__(self): return str(self.user) @property def profile_picURL(self): try: url = self.profile_pic.url except: url = " " return url def get_absolute_url(self): return reverse("home") Views.py def FollowView(request,pk): user = User.objects.get(id=pk) profile = Profile.objects.get(user=user) following=False if profile.followers.filter(id=request.user.id).exists(): profile.followers.remove(request.user.profile) request.user.profile.following.remove(profile) following=False return redirect('home',{'following':following}) else: profile.followers.add(request.user.profile) request.user.profile.following.add(profile) following = True return redirect('home',{'following':following}) return render(request,'registration/show_profile.html') show profile.html page This part of the html deal with the logic. The page is big so I don't want to bore you.However i can provide it if it will be helpful <div class="column3"> <div class="colum2-title cl3"><h3 class="text-white">People to Follow</h3></div> <div class="people-to-follow"> {% for user in users %} {% if not user.is_superuser%} <h6><h5 class="fullname">{{user.first_name}} {{user.last_login}}<h5 class="username">@{{user.username}}</h5></h6> <h5 class="username">{{request.user.is_superuser}}{{user.id}}{{request.user.profile.following.count}}</h5> <form action="{% url 'follow' user.id %}" method="POST"> {% csrf_token %} {% if following %} <button …
