Select option should not reset after refreshing the page
I'm trying to display list of candidates who took the test. There's a select tag which is used to display the hiring status. There's a dropdown menu against every candidate. I want the dropdown value to be saved to the DB and everytime I refresh the page open the project, that same dropdown value should be displayed which was saved in DB. Here's my code HTML <td> <form method="POST"> <select class="hiring-status" id="hiring" name="hiring_status" > <option selected disabled hidden value="shared">Test Shared</option> <option value="completed">Test Completed</option> <option value="under_review">Test Under Review</option> <option value="hr">HR Round</option> <option value="bg-check">Background Check</option> <option value="technical">Technical Round</option> <option value="assignment">Assignment Given</option> <option value="management">Final Round (Management)</option> <option value="hired">Hired</option> <option value="rejected">Rejected</option> </select> </form> </td> views.py def hiring_status(cls,request :HttpRequest): if request.method=="POST": hiring_status=request.POST('hiring_status') hiring_status.save() return render(request,'pages/test/list.html') else: return render(request, 'pages/test/list.html') models.py class Hiringtatus(enum.Enum): test_completed=1 test_under_review=2 hr_round=3 background_check=4 technical_round=5 assignment_given=6 final_Round=7 hired=8 rejected=9 class Test(BaseModel): hiring_status = Column(ChoiceType(Hiringtatus, impl = Integer())) I added below code but it works for the first dropdown menu and if I close the server/output window, it goes back to default value. var selectedItem = sessionStorage.getItem("SelectedItem"); $('#hiring').val(selectedItem); $('#hiring').change(function() { var dropVal = $(this).val(); sessionStorage.setItem("SelectedItem", dropVal); }); This is a sample output image -
NoReverseMatch when using NamespaceVersioning in django
I'm trying to implement versioning in django. My project urls.py looks like: url(r"^v1/sites/", include((site_urls, "sites"), namespace="v1")), url(r"^v2/sites/", include((site_urls, "sites"), namespace="v2")), in my settings/base.py I added: REST_FRAMEWORK = { "DEFAULT_VERSIONING_CLASS": "rest_framework.versioning.NamespaceVersioning", "DEFAULT_VERSION": "v1", } This works for the default version (v1). If I run a test class, it works. But when I try to test a v2 version test like: def test_get_all_sites_admin_version_2(self): self.client.force_login(self.admin_user) url = reverse("v2:admin-site-list") response = self.client.get(url) self.assertEqual(response.status_code, status.HTTP_200_OK) I got following error: django.urls.exceptions.NoReverseMatch: Reverse for 'admin-site-list' not found. 'admin-site-list' is not a valid view function or pattern name. Do I need to configure something else? -
Python: How to stream audio from firebase cloud storage
I know this question has been asked multiple times but they all refer to a different platform in a different language. I'm trying to achieve audio streaming via my django(Web framework) application, think of this app as some sort of 'Spotify' or 'Soundcloud'. Ive also heard that firebase Storage doesn't support special media streaming protocols, such as RTSP, so does this mean that streaming is impossible? -
Automating Django Deployment
We have a team working on a product (using Python/Django). Every time, a feature is completed or a bug is resolved, it is first tested locally, then pushed to the staging server. We (the developers) then have to ssh into the server, take the latest pull, run some migrations, restarting our daemon script and then finally, restart the server (we're using Apache). If there are some updates in the requirements.txt, we then have to install it again so that our virtual environment is updated. We also have QA Engineers but for most part, they are manual testers, they also do Automated testing but for now that's rare. I want to automate this whole process i.e once the changes are pushed, a pull is taken on the server (in our case it's staging server, will also include Production server), scripts are run and Apache is restarted. I'm looking for recommendations on which tool/methodology to use that will help achieve my goal in the longer run? -

Django resize and crop picture form errors with AWS S3
I'm trying to create a crop and resize modal on my website so the user is able to resize and crop its picture to the square format I need. I am using this tutorial.

When new user signup, it does not create a profile associated with it, when I try accessing the profile, I got response as RelatedObjectDoesNotExist at /accounts/profile/ User has no profile. What might went wrong here ? The following code snippets are from users app of my Django project. apps.py class UsersConfig(AppConfig): name = 'users' def ready(self): import users.signals signals.py @receiver(post_save, sender=User) def create_profile(sender, instance, created, **kwargs): if created: Profile.objects.create(user=instance) @receiver(post_save, sender=User) def save_profile(sender, instance, **kwargs): instance.profile.save() models.py class Profile(models.Model): user = models.OneToOneField(User, on_delete=models.CASCADE) address = models.CharField(max_length=500,null=True,blank=True) phone = models.PositiveIntegerField(null=True,blank=True) forms.py class UserRegisterForm(UserCreationForm): email = forms.EmailField() class Meta: model = User fields = ['username', 'email', 'password1', 'password2'] class UserUpdateForm(forms.ModelForm): email = forms.EmailField() class Meta: model = User fields = ['username', 'email'] class ProfileUpdateForm(forms.ModelForm): class Meta: model = Profile fields = ['address','phone'] (git hub repo of following tutorial : https://github.com/CoreyMSchafer/code_snippets/tree/master/Django_Blog/11-Pagination/django_project/users), If you don't know the answer , kindly up vote for more reach. -
Embedding external links using the file:/// protocol in Django
I would like to use Django to link to a file located on a server in a local network. Let's say the server name is \\server When I add a link to a local html test file, it works: <a href="file://///server/subpath/image.jpg">link</a> However, when use the exact same line in a Django template, it does not work. Clicking the link does not do anything. I ran a few checks: Firefox allows me to open the link in a new frame, but does not display the image, even if I hit Refresh. It does however load the image when I click the address bar and press Enter. Chrome does not even let me open the link in a new frame. It displays about:blank#blocked in the title bar if I try. This leads me to believe that this is deliberate behavior by Django, likely a security feature to prevent accidental access to local files. I wonder how Django does this though because when I look at the website's source code, it looks perfectly fine. The links show up as they should and if I copy the source code to a local file everything works as I expect. Can someone clarify whether this is … -
Django NamespaceVersioning example/how to start
I need to implement versioning on our application. I read the django docs about it: https://www.django-rest-framework.org/api-guide/versioning/#namespaceversioning But I find it quite short and incomplete? I started with changing my urls.py in my app as the docs mentioned: re_path(r"^v1/sites/", include(site_urls, namespace="v1")), re_path(r"^v2/sites/", include(site_urls, namespace="v2")), and added this to my settings.base "DEFAULT_VERSIONING_CLASS": "rest_framework.versioning.NamespaceVersioning", Now I get following error: django.core.exceptions.ImproperlyConfigured: Specifying a namespace in include() without providing an app_name is not supported. Set the app_name attribute in the included module, or pass a 2-tuple containing the list of patterns and app_name instead. When I add this like: re_path(r"^v1/sites/", include(site_urls, app_name="sites", namespace="v1")), re_path(r"^v2/sites/", include(site_urls, app_name="sites", namespace="v2")), I get the error: TypeError: include() got an unexpected keyword argument 'app_name' Also I want to make sure there is a default version when no version is given. How can I do this? -
How to use factory.LazyAttribute with Faker() functions
I am using factory_boy to build some fixtures in Django. I want to use factory.LazyAttribute to build one attribute based on the condition of another attribute. class MyFactory(factory.django.DjangoModelFactory): class Meta: model = MyModel title = 'My Title' if random() < 0.5 else None description = factory.LazyAttribute( lambda a: factory.Faker( 'paragraph', nb_sentences=1, variable_nb_sentences=False ) if a.title else None) However, this returns a string being <factory.faker.Faker object at 0x000001B10597BB20> rather than executing the correct paragraph generation. Where am I going wrong?
