Why is Django not able to match URL with trailing slash?
I'm using using the Django rest framework. I'm using Postman with query parameters in the URL. http://localhost:9090/api/payment_management/?cutoffDate=2022-08-05T00:00:00.000Z and my urls.py # this is a child of "/api", using include in the root urls.py urlpatterns += [path('payment_management/', get_cutoff)] I explicitly put a trailing slash at the end of the url. But I get the following from the shell Not Found: /api/payment_management/ [08/Aug/2022 18:33:32] "GET /api/payment_management/?cutoffDate=2022-08-08T00:00:00.000Z HTTP/1.1" 404 I literally put a trailing slash and it's giving me an error. Am I missing something here? APPEND_SLASH is set to true in the settings. -

MySQL database breaks while running too many tests in django

Django and JS for loop: how to change a variable value into {%static 'path' %}?
I'm trying to find out how to change a path in a picture having JS logic in the Django template. As an example - according to logic in the JS script - change from: hangman_game/img/s0.jpg to hangman_game/img/s1.jpg then to hangman_game/img/s2.jpg ect In the previous framework, it was working. But now, I'm migrating a page to the Django framework. Almost all are ready, but JS for loop syntax mentioned previously isn't working and I'm looking for a way: how to properly set a for loop that will generate a new path to the picture in the HTML file. in my html file I have: <div id="gallows"> <img src="{% static 'hangman_game/img/s0.jpg' %}" alt="" /> </div> This part is ok. The problem is, that this div is linked to for loop in js file where I previously had: var errorCount = 0; if(matched == true) { // errorCount for changing picture: errorCount++; var picture = "img/s" + errorCount + ".jpg" document.getElementById("gallows").innerHTML = '<img src="'+picture+'"alt="" />'; Outside Django, it was working, but after migrating to Django it stopped (obviously). Because JS var picture is a string, I'm pretty sure that I can use {% static %}, but I don't know how. I tried to … -
Testing django migration with sqlite django.db.utils.NotSupportedError
I am upgrading a django project. And I need to run tests. There is a test for the migration of a database scheme, but I receive an error: "django.db.utils.NotSupportedError: SQLite schema editor cannot be used while foreign key constraint checks are enabled. Make sure to disable them before entering a transaction.atomic() context because SQLite does not support disabling them in the middle of a multi-statement transaction." Not only is this error message really long, but I also have no idea left how to fix it. I already tried turning of foreign key checks using PRAGMA foreign_keys = 0;. Is this the right approach? Please help me I am stuck here for days now. executor = db.migrations.executor.MigrationExecutor(db.connection) old_apps = executor.loader.project_state(self.migrate_from).apps executor.migrate(self.migrate) # this line fails This code is run before atomics = {} for db_name in cls._databases_names(): atomic = transaction.atomic(using=db_name) atomic._from_testcase = True atomic.__enter__() atomics[db_name] = atomic return atomics Is there anything I misunderstood? -

filter method in try block is not working in django
I have a model called properties which contains product details with the respective user IDs. The user id is called uid in the model.

How can I send a post request in Django Rest Framework where a key has list of json objects?
I am new to Django Rest Framework and django itself. I want to post a request wherein a key has a list of objects. So far, I have created the User_parameter model and I am passing it as a foreign key. I am lost and do not know what to do from here on. Do I need to override create() in the User_Parameters_Serializerserializer or something entirely different? I have added code for my models.py, serializer.py, the function-based view where I am handling the post request and my desired post request outline. Thank you for your time. I really appreciate it. # The post request I want to send looks like this: { "model_path": "some path", "data_path": "some path for csv", "sep": ",", "target_column": "target_column", "label_column": "lable_column", "function_names": "some strings", "user_params": [{ "standard_deviation": between[1-3], "direction": 0 OR 1, "feature_list": "some strings" }] } #models.py class User_Parameters(models.Model): def validate_standard_deviation_number(value): if value not in range(1,4): raise ValidationError( _('%(value)s is not in range: [1-3]'), params={'standard deviation': value}, ) def validate_direction(value): #### 0 - Negative #### 1 - Positive if value not in range(0,2): raise ValidationError( _('%(value)s needs to be either 0 (Negative) or 1 (Positive)'), params={'direction': value}, ) standard_deviation = models.IntegerField(default=1, validators=[validate_standard_deviation_number]) direction = … -

Copy Django Model Input into another Django Database
I am trying to figure out if there was a way that once I uploaded something to one of my Django database files, that, that same upload would also upload to another database file, so if I go to delete one of them, it is saved in the other. class CompanyInfo(models.Model): company_name = models.CharField("Company Name", unique=True, max_length=50, default="") # Identifiers identifier = models.IntegerField(default=0) # Company Information sector = models.CharField("Sector", max_length=50,default="") location = models.CharField("Location", max_length=100, default="") year_founded = models.IntegerField("Year Founded", default=2000) company_description = models.TextField("Company Description", default="") state_registered_in = models.CharField("State of Registration", choices=states_list, max_length=2, default=2) company_url = models.URLField("Company URL", max_length=200, default="", blank=True, null=True) phone_number = models.CharField("Phone Number", max_length=20,default="") company_logo_url = models.ImageField("Company Logo", upload_to=None, height_field=None, width_field=None, max_length=100, blank=True, null=True) facebook = models.URLField("Facebook URL", max_length=200, default="", blank=True, null=True) linkedin = models.URLField("Linkedin URL", max_length=200, default="", blank=True, null=True) instagram = models.URLField("Instagram URL", max_length=200, default="", blank=True, null=True) email = models.EmailField("Email Address", max_length=40,default="") def __str__(self): return "{} from {}".format(self.company_name, self.location) Basically, once these values are created for the "CompanyInfo" class, I want it to also upload itself into another Django class in the exact same way, so if I eventually delete the input in the "CompanyInfo" class, there will still be a saved version in the other created … -
Best practice for Django inline images in TextField?
I have a portfolio site that I am building, and I will be porting a bunch of posts from my GitHub sites, all in Markdown. Thankfully, I have Markdown, and LaText math is working great on the site. However, I can not get images working in the blog body, which is a TextField. I have images working elsewhere on the site. I am looking at django-tinymce and django-inline-media as possible solutions. Any thoughts on these or other alternatives? This is what I have tried in my body so far, with many variations on the path to the image: ### MD ![img]("images/my_image.jpg") ### HTML <img src= {{ "images/my_image.jpg" }} alt="My image"> With the following turned on in urls.py. from django.contrib.staticfiles.urls import staticfiles_urlpatterns ... urlpatterns += staticfiles_urlpatterns() ### Static <img src="{% static "images/my_image.jpg" %}" alt="My image" /> -

django permissions not being added to groups

Upload Image in Django with Ajax
This question is asked many times. And after long time trying I gave up. I try to upload an image to the server with an Ajax function. The Ajax function does submit quite a lot of data (I deleted the unnecessary part). The console.log gives me an empty array. What is wrong with my function?

React Django Stripe Button
I have a react frontend and a Django/DRF backend. I am trying to create a button on the frontend that allows users to purchase a product via stripe. The below react code works fine for purchasing item. However, it does not register the purchase under specific user, meaning that you can purchase an item, but it is not linked to any user because it does not have the token (identifying the user who is making the purchase). return ( <section> <div className='product'> <img src='https://i.imgur.com/EHyR2nP.png' alt='The cover of Stubborn Attachments' /> <div className='description'> <h3>Stubborn Attachments</h3> <h5>$20.00</h5> </div> </div> <form action={`${API_URL}/api/stripe/create-checkout-session`} method='POST' > <button className='button' type='submit'> Checkout </button> </form> </section> ); }; Here is what I tried: const Playsub = () => { const purchase_item = () => async dispatch => { if (localStorage.getItem('access')) { const config = { headers: { 'Content-Type': 'application/json', 'Authorization': `JWT ${localStorage.getItem('access')}`, 'Accept': 'application/json' } }; const body = JSON.stringify({ token: localStorage.getItem('access') }); const res = await axios.post(`${API_URL}/api/stripe/create-checkout-session`, body, config) .then((res) => { console.log(res.data) }) .catch(err => { console.log(err.response.data) }); }}}; return ( <section> <form> <button onClick={purchase_item} className='button' type='submit'> Checkout </button> </form> </section> ); }; export default Playsub; The above code when clicking on the button created gives … -
How to send a message by time in a datatimefield in DJANGO?

With Django Websockets, how can I subscribe the current user to a new group from views.py
In Django, I have models.py with Collection and Members as a relationship to them: # models.py class Collection(models.Model): name = models.CharField(max_length=100, null=False, blank=False) class Member(models.Model): account = models.ForeignKey(User, related_name="account_set", on_delete=models.CASCADE) collection = models.ForeignKey(Collection, related_name='members', on_delete=models.CASCADE) And I have a websocket for notifying members whenever we have changes in a collection that the user is member of. For that, I have MainConsumer, shown below. # consumers.py class MainConsumer(WebsocketConsumer): def connect(self): user_id = self.scope['user_id'] collection_ids = Member.objects.filter(account_id=user_id).values_list("collection_id", flat=True) for collection_id in collection_ids: async_to_sync(self.channel_layer.group_add)(f'collection_ws_{collection_id}' , self.channel_name) self.accept() Works like a charm. I can comunicate perfectly. Question is the following: If I create a new collection, I need somehow to tell my MainConsumer that the requested user should now receive notifications from this new collection as well. # views.py class CollectionCreate(generics.CreateAPIView): permission_classes = [IsAuthenticated, ] def create(self, request, *args, **kwargs): collection = Collection.objects.create(name=request.data['name']) # Create a member as admin member = Member.objects.create( collection=collection, account=request.user, ) ** -- Here I want to 'subscribe' the current user to this new collection as well, but I cant figure out how... -- ** return JsonResponse({"payload": CollectionSerializer(collection, many=False).data }, status=200) Worth mentioning that I could "reload" my websocket in the frontend and it works, but it seems a bit …
