How does Django QuerySet cache work from get() method
I understand that query sets are cacheable and they get evaluated (DB gets hit) when the data set is first iterated on. But what happens with get() method (ex: MyModel.objects.get(id=1)). When does the DB get hit and when do we use a cached result? I am specifically interested in a flow with an API GET request (if that makes a difference). If I have several MyModel.objects.get(id=1 calls within the request lifecycle, will I be hitting the DB every time I call that get() or will I be using cached results ? -

How to load manifest.json in django from react build folder? manifest.json not found error
Im developing a website using react bundled inside django servic static files. Everything appears to be working but my react is not working properly due to django not finding the manifest.json files. I have tried a few solutions that i found here in StackOverflow: mainly adding: path('manifest.json', TemplateView.as_view(template_name='manifest.json', content_type='application/json'), name='manifest.json') to my Django urls.py file and that worked to an extent, but then the error i get changes to: http://localhost:8000/logo192.png 404 (Not Found) Error while trying to use the following icon from the Manifest: http://localhost:8000/logo192.png (Download error or resource isn't a valid image) I also noticed that the react favicon was not loading so I found a fix here for that by using: <link rel="icon" href="http://localhost:8000/media/favicon.ico" /> instead of <link rel="icon" href="%PUBLIC_URL%/favicon.ico" /> Where the media folder is the folder im serving my urls.py file in django as my media root. That got the favicon working but the logo192.png not found error still persists, but when I tried the same method for the png file i get the same error. How do I fix it? -
Django Value Error: Cannot Assign Queryset must be instance, ManyToMany Relationship
I have built a model,OpeningDays, to manage a ManyToMany relationship (opening_days field in my BookingManagement model), since I wanted to add some additional data to each instance. I am using the 'through' approach as you can see from my models.py. Within my form, I have a CheckboxSelectMultiple, and for each day which is checked I want to create a model instance.

The exception is being raise on this line of my code: if form.is_valid(): In order to try and solve this I have attempted to iterate through the queryset in my view with a for loop.

How to make htmx colour animations work with Django?

Any way to optimize my file and folder pattern
I am writing app, where i have folders and files component. I think the way it works is slow. I have 2 models: BookmarkFolder and Bookmark, they're connected through ForeignKey so each folder could have multiple bookmarks. In my template I've listed folders and I can open each by clicking on "Extend" button, it renders all files under it (I use htmx). list of folders. The problem is every time I open folder it makes query to database and it seems slow to me. How can I optimize it to work faster or maybe there's better ways to implement this folder and files pattern without using JS framework? -
In Django Template: display the sum of calculated variables
right now I wonder if there is a way to show up the sum of variables in a Django-Template. What I mean is, if i have variables of the same kind, is there a template-sided function to add them? I know, that the "logic" should be normally outside a template, so i wrote a function that does the calculation i want to see in the template: def mission_duration(self): duration = self.end - self.begin return duration.days and use it in template by {{ mission.mission_duration }} and it works fine. But if i have several of these variables in a template, is there an easy way to sum their values up and show the result? Right now, the variables are displayed by querying the database going through a for-loop. The result is likely to be displayed outside of the loop elswhere in the template... or on the other side: how can i put this on model/view.py to solve the problem outside the template? missions are in an oneToMany relationship table to "employees"...and normally data of employees are displayed. so for a model/view solution i have no idea at the moment, how to cycle to alle mission entries of an employee to build … -

picking django template variable from rendered template to use in javascript
I am still new to django and struggling with this issue : I have a price slidebar in html that i picked up from a template. In html, the bar looks like this : <div class="price-range ui-slider ui-corner-all ui-slider-horizontal ui-widget ui-widget-content" data-min="33"" <!-- to replace with :{{ price_max.product_price__max }}" --> data-max="15" ></div> <div class="range-slider"> <div class="price-input"> <p>Prix:</p> <input type="text" id="minamount" /> <input type="text" id="maxamount" /> </div> </div> </div> <a href="#">Filter</a> I upload price_max and also price_min correctly from the view as they can be directly displayed on the webpage as text. But the slidebar uses javascript to be rendered and picks up those data-min and data-max values to display the dynamic result like this : enter image description here the javascript: /*------------------- Range Slider --------------------- */ var rangeSlider = $(".price-range"), minamount = $("#minamount"), maxamount = $("#maxamount"), minPrice = rangeSlider.data('min'), maxPrice = rangeSlider.data('max'); rangeSlider.slider({ range: true, min: minPrice, max: maxPrice, values: [minPrice, maxPrice], slide: function (event, ui) { minamount.val( ui.values[0]+'€'); maxamount.val( ui.values[1]+'€'); } }); minamount.val( rangeSlider.slider("values", 0)+'€'); maxamount.val( rangeSlider.slider("values", 1)+'€'); replacing data-min and data-max by django templates variables doesn't work, i'm still unclear exactly why but i suppose it has to do with django rendering order. Another difficulty is that i … -

So if someone moves the slider, the page is reloaded and the slider is at the same position as the person has moved it. In order to make this happen, I pass the 'workload_min' and 'workload_max' back to my template 'myfile.html'. Now the question is, how can I trigger the trigger the event listener when the slider is moved? I have tried with dispatchEvent(event), however, since the values are passed back to the template, the dispatchEvent(event) will be triggered again and again, in a endless reloading of the page. I have also tried with simple addEventListener('input', function ()) but the change of the input field, trough movement of the slider is not detected. Does someone know how to handle this problem? html: <input form="test-form1" type="text" name="workload1" id="workload1" readonly="readonly"> <input form="test-form1" type="text" name="workload2" id="workload2" readonly="readonly"> <div … -
How can I set this？

Django REST Framework - Weird Parameter Shape due to JSON Parser?
Currently I'm contacting my APIViews through AJAX requests on my frontend. config = { param1: 1, param2: 2, param3: 3 } $.ajax(APIEndpoints.renderConfig.url, { type: APIEndpoints.renderConfig.method, headers: { "X-CSRFToken": csrfToken }, data: { "config": config, "useWorkingConfig": true } } However, when I receive the data in my APIView, I get an object with the following shape: { "config[param1]": 1, "config[param2]": 2, "config[param3]": 3, "useWorkingConfig": true } According to different sources that I have checked, DRF does support nested JSON objects, so what am I missing? Is this something to do with the default behavior of the JSON Parser? It doesn't seem to be very useful, as you would basically need to preprocess the data before using your serializers (since they expect a nested structure). The same happens with lists, with your parameters being received as list_param[] instead of list_param. If its useful for anything, these are my DRF settings REST_FRAMEWORK = { 'DEFAULT_SCHEMA_CLASS': 'drf_spectacular.openapi.AutoSchema', 'EXCEPTION_HANDLER': 'django_project.api.exception_handler.custom_exception_handler', # Camel Case Package Settings 'DEFAULT_RENDERER_CLASSES': ( 'djangorestframework_camel_case.render.CamelCaseJSONRenderer', 'djangorestframework_camel_case.render.CamelCaseBrowsableAPIRenderer', ), 'DEFAULT_PARSER_CLASSES': [ 'rest_framework.parsers.JSONParser', 'djangorestframework_camel_case.parser.CamelCaseFormParser', 'djangorestframework_camel_case.parser.CamelCaseMultiPartParser', 'djangorestframework_camel_case.parser.CamelCaseJSONParser', ], 'JSON_UNDERSCOREIZE': { 'no_underscore_before_number': True, }, } Its very probable that Im just missing something or its an intended behavior that Im not aware of.
