Django - Unable to Redirect to Update Form and Update Values
I've prepared a django app that would take input from user after the user logs in. Once the user logs in they can input values to form and post it to db. However, I need to provide user the capability to update the already existing entry based on conjugate primary key Station and Date. I've added a update button on page form to update entry in case if user inputs values for already existing primary key. I need to achieve two things Enable update button only if user inputs values for already existing primary key. Though update button is enabled but I am unable to redirect to update_form page. Currently I am unable to figure out why can't I redirect to update_form page. I am getting following error django.urls.exceptions.NoReverseMatch: Reverse for 'update_form' with arguments '('',)' not found. 1 pattern(s) tried: ['\\^\\(\\?P(?P<pk>[^/]+)\\[0\\-9\\]\\+\\)/update_form/\\$$'] Following are all relevant scripts being used: Models.py from django.db import models from django import forms from django.db import models from django.conf import settings from django.contrib.auth.models import User # Create your models here. class ManHour(models.Model): class Meta: unique_together = (('date', 'station'),) station_choices = ( ('KHI','Karachi'), ('ISB', 'Islamabad'), ('LHE','Lahore'), ) station = models.CharField( max_length=3, choices=station_choices, ) date = models.DateField() date_time … -
upload a test file using moto and boto3
I want to test conduct testing on imported files from aws. I mock s3 using moto, in order to not mess with actual data. However, now the aws seems to be empty, thus I decided to upload some test file on mocked s3. How can I do so? This is my setup, Conftest.py: @pytest.fixture(scope='function') def aws_credentials(): """Mocked AWS Credentials for moto.""" os.environ['AWS_ACCESS_KEY_ID'] = 'testing' os.environ['AWS_SECRET_ACCESS_KEY'] = 'testing' os.environ['AWS_SECURITY_TOKEN'] = 'testing' os.environ['AWS_SESSION_TOKEN'] = 'testing' @pytest.fixture(scope='function') def s3(aws_credentials): with mock_s3(): yield boto3.client('s3', region_name='us-east-1') Test file: class TestLoadRecommendations: @pytest.fixture(autouse=True) def _setup(self, s3): self.bucket = s3.create_bucket(Bucket=settings.SERVER_DATA_S3_BUCKET) self.bucket.upload_file("tmp/recommendations-2021-04-13T17_28_06.csv", "tmp/recommendations-2021-04-13T17_28_06.csv") However, instead uploading it throws an error TypeError: expected string or bytes-like object but I am sure that I use incorrect command for file upload. Could anybody help? Thanks! -
Django: Camera does not work when in production, 500 Internal Server Error
!!First, to say that I am aware there are similar issues here, but I was not able to find a solution!! I have deployed my Django app and it works fine except for the camera function. It works fine locally but not on the server. The relevant code is: views.py . . from .camera import VideoCamera def display_camera_frame(request): camera = VideoCamera() response = StreamingHttpResponse(start_camera(camera), content_type='multipart/x-mixed-replace; boundary=frame') return response def start_camera(camera): frame_index = 0 while True: frame = camera.get_frame() if frame_index%10 == 0: with open(f"{settings.STATICFILES_DIRS[0]}/images/face", "wb+") as f: f.write(frame) f.close() frame_index+=1 yield (b'--frame\r\n' b'Content-Type: image/jpeg\r\n\r\n' + frame + b'\r\n\r\n') Django HTML Page <img id="face_image" width="510" height="360" src="{% url 'app:display_camera_frame'%}"> And when on browser (in production), it displays the code in the Inspect tab like this: <img id="face_image" width="510" height="360" src="/display_camera_frame/"> I would really appreciate any help :) -
How do i check for duplicates in django sqlite database
I'm working on a django website for movie site, which uses an api to fetch relevant data about specific movies and saves them to django sqlite3 database. However it seems each time i refresh the page the request to the api gets sent again and the data keeps on adding itself to the database. How can i validate the parameters so anytime i make a request it checks if it exists in the database and if it does it just renders directly from the database? This is the home view function def home(request): query = request.GET.get("title") all_movies = None if query: name = request.GET['title'] # url = 'http://www.omdbapi.com/?apikey=7531b4db&s='+name+'' url = 'https://api.themoviedb.org/3/search/movie?api_key=73b26cd6e71f57e195d7a253e3911b74&language=en-US&query='+name+'&page=1&include_adult=false' response = requests.get(url) data = response.json() movies = data['results'] poster_link = 'https://image.tmdb.org/t/p/w500' for i in movies: movie_data = MovieClass( title = i['original_title'], year = i['release_date'], rating = i['vote_average'], poster = poster_link + str(i['poster_path']), description = i['overview'] ) movie_data.save() all_movies = MovieClass.objects.all().order_by('-id') all_movies = MovieClass.objects.filter(title__icontains=query) else: url_display = 'https://api.themoviedb.org/3/movie/popular?api_key=73b26cd6e71f57e195d7a253e3911b74&language=en-US&page=1&' response = requests.get(url_display) data = response.json() movies = data['results'] poster_link = 'https://image.tmdb.org/t/p/w500' for i in movies: movie_data = MovieClass( title = i['original_title'], year = i['release_date'], rating = i['vote_average'], poster = poster_link + str(i['poster_path']), description = i['overview'] ) movie_data.save() all_movies = MovieClass.objects.all().order_by('-id') … -
How to make a sidebar sticky?
I have a site that has a bootstrap 4 navbar on top, which has the class "sticky-top". It does not have a fixed height, as far as I know. Below that I have a container-fuid div and in it a sidebar on the left and a main div to the right. I would like to have that sidebar on the full height, meaning from the bottom of the navbar to the bottom of the page and at the same time I would like it to remain sticky, when I am scrolling down in the main window. I have tried a lot with "position: sticky" and so on, but until now I did not find the right class or properties to get this working. Do you have advice for me? -
Django - How to sort Post model by votes?
I'm trying to sort posts in views.py with the greatest number of votes at the very top to the least at the bottom. Here's what I have so far: Post model in models.py class Post(models.Model): title = models.CharField("HeadLine", max_length=256, unique=True) creator = models.ForeignKey(User, on_delete= models.SET_NULL, null=True) created_on = models.DateTimeField(auto_now_add=True) url = models.URLField("URL", max_length=256,blank=True) description = models.TextField("Description", blank=True) votes = models.IntegerField(null=True) comments = models.IntegerField(null=True) def __unicode__(self): return self.title def count_votes(self): self.votes = Vote.objects.filter(post = self).count() @property def sort_by_votes(self): return Vote.objects.filter(post = self).count() def count_comments(self): self.comments = Comment.objects.filter(post = self).count() list of posts in views.py def NewPostListView(request): posts = sorted(Post.objects.all(), key=lambda p: p.sort_by_votes, reverse = True) for post in posts: post.count_votes() print(post) post.count_comments() context = { 'posts': posts, } return render(request,'postlist.html', context) I'm trying to do the equivalent of posts = Post.objects.all().order_by('count_votes'), but I get a "Cannot resolve keyword" error. So far, using the sorted() seems to work, but then after upvoting a post, the list gets out of order. How can I get a QuerySet to sort posts by votes? -

I have a model class StudentEfficacy(models.Model): class FatherEducation(models.IntegerChoices): NoEducation = 0, _("No Education") PrimaryEducation = 1, _("Primary Education") SecondaryEducation = 2, _("Secondary Education") GraduateStudy = 3, _("Graduate Study") PostGraduateStudy = 4, _("Post Graduate Study") DoctorOfPhilosophy = 5, _("Doctor of Philosophy") student_efficacy_id = models.AutoField(primary_key=True) father_education = models.IntegerField(choices=FatherEducation.choices) study_time = models.IntegerField("Study Time in mins") I want to dynamically check if the field has choices defined. for example I want to do something like below: stud = StudentEfficacy.objects.get(pk=1) if stud.father_education has choices defined: print(stud.father_education) elif not stud.study_time has choices defined: print(stud.study_time) Actually in the example above I have given fixed models and fields but actual use would be like below: for model_inst in models_list: for field in model_field_list[model_inst._meta.verbose_name] if model_inst.getattr(field) has choices defined: print("Something") else: print("Something else") -
Return live search results in order of keystrokes - Django and JavaScript
I am trying to build a search bar that allows user to search database for the names of stored venues. I want it to be a live search that returns results as the user types. Similar to google. I have gotten the feature almost complete, it dynamically returns venues as the user types and returns venues that contain the letters being typed. Problem: I can't figure out how to return venues that contain letters IN ORDER of typing. Example from google. How mine shows up. Here is my JS Function: const search = function() { let searchTerm = document.getElementById("search-box").value; $.ajax({ type: 'GET', url: '/electra/search/', data: { 'search_term': searchTerm }, success: function(data) { data.forEach(([cafeName]) => { var cafeName = cafeName; var searchList = $( `<div> <ul class="list-item border-top" data-idtext="${cafeName}" id="${cafeName}">${cafeName}</ul> </div>` ); searchList.appendTo('#search-results'); }); $("ul").click(function(event) { var selectedVenue = event.target.id; $("#search-results").empty() getVenueDetails(selectedVenue) }); } }); }; And here is the views.py function: def search(request): template_name = 'testingland/write_image.html' search_term = request.GET.get('search_term', None) print(search_term) qs = mapCafes.objects.filter(cafe_name__icontains = search_term)[0:5] return JsonResponse([ [cafe.cafe_name] for cafe in qs ], safe=False) -

Django Allauth sign up event with Google analytics
Trigger events on successful sign up & sign in Trying to track a user that successfully signs up with a social account, using Google analytics and Google tag manager. Have you achieved this using these tools? So far I am thinking something along these lines, and then passing the login success as a url parameter. This doesn't seem like the most elegant solution and does not solve the issue of identifying a new user vs an existing user. Any help appreciated.
