Django change Boolean after POST
I'm trying to clone linkr.ee just for learning django A page looks like this: Each user User has a page On this page one user can have multiple links A link can have a password field to unlock the link if a user setted the password to True/False I created the model here: class Field(models.Model): user = models.ForeignKey( settings.AUTH_USER_MODEL, default=None, null=True, on_delete=models.CASCADE, ) title = models.CharField(max_length=255) url = models.CharField(max_length=255) creator_adress = models.GenericIPAddressField(null=True) password_secured = models.BooleanField(default=False) password = models.CharField(max_length=100, blank=True, null=True) So if password_secured is checked (True/False), the link will have the password field aswell. My Problem: I'm having issues with giving each link one the page the which is password secured a form. If one link has password_secured True (and password) -> Form needed for each link which has password -> if password correct (form valid) -> password_secured False -> link unlocked The Template: #here just a for loop to display every object of the specific user into the html template <a {% if i.password_secured == False %} href="{{i.url}}{% endif %}"></a> #for loop end Simple Template meaning: If password secured False -> put the href in the Link(Button) If password secured True -> Password form must be correct -> set … -
Placement input text no showing
When I add another CRSF Token, it will not show the placeholder texts. Without this second token. It will not allow for me to save the form. I do not know how to make this last placeholder visible again when adding the token. Any Help would be appreciated. If any other files are needed such as the views class.

Django media uploads to Amazon S3 and restricting access to certain users
I am creating a flutter application with Djano backend where users can create/join groups and upload files (pictures, videos etc) to the group. I set up AWS S3 storage to handle media file uploads. However, now I'm at a point where I want only members of a group in the app to be able to see those files/pictures and restrict access to those files/pictures where you are not a member of the group. right now My bucket settings is set to public and anyone that has a link to the URL can access/view that file in the browser. How would I implement if someone grabs a hold of that URL , they shouldn't be able to access the file by going to the link. essentially, some content like profile pictures can be public and anyone can access that but no one can just go to their browser and type in a URL for a certain file link and access it. How would I go about doing this? Are there any good tutorials that you can link me or documentation that discusses this? -
I cannot post data - Django

How to get only the last month's records present in the database, using queryset django?
I need to get only the objects of the last month present in the DB. I don't mean the last 30 days or the last calendar month, but the most recent month recorded in the database... I've seen that django has the latest() function that returns the most recent object in the table based on in the given field(s), however I want it to return multiple objects based on the given month. revisoes = Revisao.objects.filter(apicultor__in=apicultores).order_by('-data_registro') This is the queryset I'm using, only it returns all revisions for a given beekeeper. I need it to return only revisions based on the last month of the "data_registro" field -

HTML form , not responsive while inside a div
I'm creating a web page and if i put my div inside a form it makes it non-responsive but if i put that same form outside the div, everything works just fine. I wanted to have a div called container-2 and 2 forms inside, one is on the left as you can see and the other one is a card payment method. If i try to resize my screen, the second form goes under the first one because i've set the flex-wrap:wrap; but the first form stays non-responsive. Here is the code and thanks in advance. <div class="container-2"> <form method="POST">- <div class="item" id="payment"> <div class="row"> <h4>Možnost nakupa 1: Plačilo po povzetju <small><i>(Za plačevanje s kartico je treba izbrati samo količino in vrsto izdelka!)</i></small></h4> {% csrf_token %} {% if form %} <div class="input-group"> <div style="color: red;">{{ form.name.errors }}</div> {{ form.name }} </div> <div class="input-group"> <div style="color: red;">{{ form.last_name.errors }}</div> {{ form.last_name }} </div> <div class="input-group"> <div style="color: red;">{{ form.street_name.errors }}</div> {{ form.street_name }} </div> <div class="input-group"> <div style="color: red;">{{ form.city_name.errors }}</div> {{ form.city_name }} </div> <div class="input-group"> <div style="color: red;">{{ form.email.errors }}</div> {{ form.email }} </div> <div class="input-group"> <div style="color: red;">{{ form.number.errors }}</div> {{ form.number }} </div> {% endif %} </div> … -
Django: tie two redirects to a single Update button depending on where the user came from
So, i have a rather usual "update item" page that is a class-based view which inherits UpdateView. (in views.py it looks like "class ItemUpdateView(UpdateView) and it has method get_success_url(self) defined which contains the redirect url where user will be taken after clicking "Update" button. My problem is that in my application, there are two different pages that could lead me to this "Update item" page, and depending on the page that user comes from - i want to take the user back to either pageA or pageB upon the successful update of the item. I wasn't able to find the best-practices of how to handle this anywhere on the web, so - would really appreciate the help. My guess is that I need to create an additional parameter that will be a part of the url and will contain A or B depending on the pageA or pageB that user came from, i.e. the url itself would be something like '/itemUpdate/int:pk/sourcepage' => '/itemUpdate/45/A'. Does that sound like a correct aproach or is there a better way? -
Django migrate won't work due to Postgres InsufficientPrivilege error provisioned by terraform and helm
We're are hitting a issue with our Django app and are unable to find the underlying problem. Our Django app runs on Kubernetes and is managed by Helm. When we upgrade the app, a Helm upgrade job is triggered that makes sure that a manage.py migrate is run. The migrate job runs with database admin privileges, not the customers postgres role. The error we're getting is: InsufficientPrivilege: permission denied for table RouteInstance This error must have something to do with creating a reference from a new table to a existing table, but we can't find it. Maybe it's in the Terraform resources config, or are the grants not sufficient. We don't use any extra grants since the admin account should be a real admin (Digitalocean doadmin). Any help would be awesome, we're stuck at the moment. Some context on our app deployment: The Helm template is being deployed by Terraform, the application deployment consists of: Create a subdomain record Create a namespace Create S3 buckets and a account Deploy the Helm chart (helm_release), here we use a values list with a templatefile. Between these values there are variables: postgres_user_username (used to run the app) postgres_user_password postgres_admin_username (used to perform the … -
How to prechoose an option in django form
I made a project in Django, on one page I have a list of buses with a button for each. I would like these buttons to lead to another page with ride cost calcutor, but there is one catch. One of the option in this form is a bus type, so I would like the button to lead to the form but with already chosen proper option. So if i push the button next to Volvo bus it will take me to the form and Volvo option will be chosen, if I push the button next to Setra it will be chosen in the form and so on. I tried giving every option unique id, and then in a tag href="{% url 'base_app:calc' %}#Volvo" but it only shows me the form, without choosing option. How should I go about it? -
DRF: Full Example of ListSerializer like Django's Admin-Inline?
I'm trying to wrap my mind around DRF's ListSerializer in combination with a foreignkey-model. The aim is to have something similar to Django's admin-inline Formula. Unfortunately, I can not find a full example on the documentation or SO examples: two models, two serializers and a viewset. Suppose we have a model bit like in the SO example DRF ListSerializer and ListField : class Musician(models.Model): name = models.CharField(max_length=50) comment = models.TextField(blank=True) class Album(models.Model): artist = models.ForeignKey(Musician, on_delete=models.CASCADE) name = models.CharField(max_length=100) So I try to put them in serializers like that: class AlbumSerializer(serializers.ModelSerializer): class Meta: fields = 'artist', 'title' model = Album class MusicianSerializer(serializers.ModelSerializer): class Meta: fields = 'name', 'comment', 'albums' model = Musician albums = serializers.ListSerializer(child=AlbumSerializer(), source='album_set') And then I want to build a ModelViewSet on it, so that I can work with it, just like in Django-Admin-Inline. But this is not working just like that: class MusicianViewSet(viewsets.ModelViewSet): queryset = Musician.objects.all() serializer_class = MusicianSerializer But it's difficult to test, the HTML front-end does work, and in the tests I got (in a slightly different situation) an error message something like: {'album_set': [ErrorDetail(string='This field is required.', code='required')]} which I could not understand, not even after digging hours in the source code.

Modifying the root folder only for one view or specific template (django, jquery, html)
I am trying to figure it out for several days, I am running out of time. I would need to make this works without changing the "<a href='/about'>About Text</a>" part (please, see code below).

Django + Ajax: why does it redirect to a new URL and renders the response on browser?
Based on my understanding, ajax could be used to prevent the page from reloading/refreshing/redirecting after submitting a request to the server. However, my code will redirect to display the JSON response. I used e.preventDefault() and it didn't work. Is there anything that I am doing wrong? My Django code looks like this: views.py: def projects(request): if request.method == 'POST': task_id = request.POST.get('task_id') myUser = User.objects.get(pk=request.user.id) myTask = Task.objects.get(pk = task_id) myTask.claimed.add(myUser) #add the user to the task return JsonResponse({'status': 'ok'}) projects = Project.objects.all() tasks = Task.objects.all() open_tasks = tasks.filter(status='Created') proj_dict = {} context = { 'projects' : projects, 'tasks' : tasks, 'open_tasks' : open_tasks, } return render(request, 'projects/projects.html', context) My HTML: <form action="{% url 'projects:' %}" method="POST" class='join-form' id='{{task.id}}'> {% csrf_token %} <input type="hidden" name="task_id" value={{task.id}}> <button type="submit" class=" claim-font claim-button"> Join </button> </form> Tha ajax call: <script> $(document).ready(function () { $('#join-form').on('submit', function (e) { e.preventDefault(); e.stopPropagation(); const url = $(this).attr('action'); console.log("here we are"); const task_id = $(this).attr('id'); $.ajax({ type: 'POST', dataType: "json", headers: { 'X-CSRFToken': csrftoken }, url: url, data: { csrfmiddlewaretoken: '{{ csrf_token }}', task_id: task_id, }, success: function (response) { alert(data); console.log("here we are"); }, error: function (response) { console.log('error', response); alert("shit") } }) return false; }); … -

BrowsableAPI not working with functional views
How do I make BrowsableAPI work with functional views? For example, let's say I have @api_view(['GET', 'POST']) @csrf_exempt def snippet_list(request): """ List all code snippets, or create a new snippet. """ if request.method == 'GET': snippets = Snippet.objects.all() serializer = SnippetSerializer(snippets, many=True) return JsonResponse(serializer.data, safe=False) elif request.method == 'POST': data = JSONParser().parse(request) serializer = SnippetSerializer(data=data) if serializer.is_valid(): serializer.save() return JsonResponse(serializer.data, status=201) return JsonResponse(serializer.errors, status=400) When I register in the url and acces it, the browser gives me the raw json, not the browsableapi version of it. How can I make it work? I looked up the documentation and posts but couldnt find anything, everyone is either using classes based or generics. I know this way of making views is not ideal, but I still want to know how to make a functional view "Browsable". -

However I can't "add" the Tag without saving the model and I can't save the model without adding the Tag Tests class ProjectTests(TestCase): def setUp(self): self.tag = Tag.objects.create(name="HTML5") self.project = Project( title="Oaks on Main Shopping Center", url="www.oaksonmain.co.za", image=SimpleUploadedFile( name="test-image.jpg", content=open( "static\\images\\test_images\\florian-olivo-4hbJ-eymZ1o-unsplash (1).jpg", "rb" ).read(), content_type="image/jpeg", ), description="Beautiful website created for Oaks on Main Shopping Center in Knysna!", category=Category.objects.create(name="Website"), ) self.project.save() <- Problem here self.project.tags.add(self.tag) <- Problem here def test_project_model(self): self.assertEqual(f"{self.project.title}", "Oaks on Main Shopping Center") self.assertEqual(f"{self.project.url}", "www.oaksonmain.co.za") self.assertEqual( f"{self.project.description}", "Beautiful website created for Oaks on Main Shopping Center in Knysna!", ) self.assertEqual(self.tags.count(), 3) self.assertEqual(self.category.count(), 1) self.assertEqual(self.image.count(), 1) def test_project_listview(self): resp = self.client.get(reverse("index")) self.assertEqual(resp.status_code, 200) self.assertContains(resp, self.project.title) self.assertTemplateUsed(resp, "page/index.html") Models class Project(models.Model): class Meta: ordering = ["-id"] # Always show latest projects first verbose_name_plural = "Projects" title = models.CharField(max_length=50) url = models.URLField() image = models.ImageField(upload_to=f"{title}/") description = models.TextField() category = models.ForeignKey("Category", on_delete=models.PROTECT, related_name="categories") tags = models.ManyToManyField("Tag", verbose_name="tags") … -
Why queryset.only() is ignored when using serializers?
Could you give me a hand with this issue please? I am using Django and REST Framework for my app. I want to retrieve distinct values of 1 column in a django model, for that I use a queryset with chained filters and a serializer with the option many=True. Here is my code: Specified queryset: queryset = CollectedCompaniesInfo.objects.all() queryset = queryset.only('branch').distinct('branch') Expected result: [{ "id": 16, "branch": "McDonald's" }, { "id": 80, "branch": "Wendy's" }] I am getting: [ { "id": 16, "branch": "McDonald's", "latitude": "35.94905003", "longitude": "-81.18771815", "state": "North Carolina", "address": "561 W Main Ave Taylorsville NC 28681 United States", "open_hours": "Mon-Sun 5 am - 11pm", "coordinate_x": 35.94905003, "coordinate_y": -81.18771815 }, { "id": 88, "branch": "Wendy's", "latitude": "35.24987478", "longitude": "-80.95769756", "state": "North Carolina", "address": "5501 Birmingham Pkwy Concourse A Charlotte NC 28208 United States", "open_hours": "Sun - Thu 6:30am -2am/Fri-Sat 6:30am -3am", "coordinate_x": 35.249874778495084, "coordinate_y": -80.95769756353488 }] Serializer code: serializer = CollectedCompaniesInfoModelSerializer(queryset, many=True) return Response(serializer.data, status=status.HTTP_200_OK) -
