Update Django ImageField through .update() ORM
Similar questions have been asked here: Update ImageField without forms in django, and Django ImageField is not updating when update() method is used But the answer has always been the same ("use .save() instead") - this solution does work, but because of signals on the model which I can't control, I would like to know if there are any work-arounds that can be used instead. # serializers.py from drf_extra_fields.fields import Base64ImageField from rest_framework import serializers class ProfileSerializer(serializers.Serializer): email = serializers.CharField(required=False, allow_null=True) image = Base64ImageField(required=False, allow_null=True, max_length=None, use_url=True) # views.py def get_as_base64(url: AnyStr): if url is None: return None, None full_name = url.split("/")[-1] my_base = base64.b64encode(requests.get(url).content) return my_base, full_name def do_profile_update(profile: Dict): b64_image, file_name = get_as_base64(profile.get("url")) if b64_image and file_name: *_, file_ext = file_name.split(".") b64_image = f"data:image/{file_ext};base64,{b64_image.decode('utf-8')}" build_dict = { "email": profile.get("email"), "image": b64_image, } serializer = ProfileSerializer(data=build_dict) serializer.is_valid() # returns True # serializer.validated_data = {'email': 'test@example.org', 'image': <SimpleUploadedFile: 11735acf-6d96-4c62-9e6a-8ebb7f7ea509.jpg (image/jpeg)>} Profile.objects.filter(pk=pk).update(**serializer.validated_data) # This saves the *name* of the image to the database, but no image file I understand that a ImageField is basically a CharField, and I can see the name of the image in the database, but the image isn't written to the server.

Django dynamic formset only saving last entry
I have created a page where users can enter details to forms relating to a parent model (Patient) and two child models (CurrentMed and PastMed) linked to that parent.

Django S3 : Saving images doesn't work when calling serializer
I need to create an API to upload images on a website. I've already created in my models the save method to upload and resize images. It's working correctly by the django administration page. Unfortunately, when I use my serializer, the image does not save.

How to add product to cart on a page with many products in E-commerce Vue.js / Django Rest Framework?
I am building an e-commerce website with Vue.js and Django Rest Framework. I have a page with all the latest products, that works well and fetches all the data. I can visit the details of each product and add them to the cart (on each product's page). The problem is that I don't know and can't get to add those products from the general products page where there are multiple products and get the number of products of each one of them. I created a dynamic Id for number input, but when I try to use it it says "Cannot read property 'value' of null" I understand that the number of products should be related to each one of the products, but I can't seem to understand how to do that. To sum things up: How can I add products to the cart on a page with multiple products fetched via v-for? Thank you!

Django ORM And Multiple Dynamic Databases
Disclaimer: I am still pretty new to Django and am no veteran. I am in the midst of building the "next generation" of a software package I built 10 years ago. The original software was built using CodeIgniter and the LAMP stack. The current software still works great, but it's just time to move on. The tech is now old. I have been looking at Django to write the new software in, but I have concerns using the ORM and the models file getting out of control. So here's my situation, each client must have their own database. No exceptions due to data confidentiality and contracts. Each database mainly stores weather forecast data. There is a skeleton database that is currently used to setup a client. This skeleton does have tables that are common across all clients. What I am concerned about are the forecast data tables I have to dynamically create. Each forecast table is unique and different with the exception of the first four columns in the table being used for referencing/indexing and letting you know when the data was added. The rest of the columns are forecast values in a real/float datatype. There could be anything from … -

Change django array field size depending on another field?
I am building an app that displays different courses. For each course there is a list of the different classes it has. Some courses have two classes, somo have eight, some have just one or in the future some courses may have 10 classes. It's up to the app's administrator when they register a new course class Curso(models.Model): clases = models.IntegerField(default=1) content = ArrayField(models.CharField(max_length=30),blank=False) This model will only be for the administrator. I want to store the different classes (just their names) in an array. But theres no need to show 8+ fields if the admin is just going to fill one in... Or is that the correct approach? I want the admin to have an integer field where she types in how many classes the course has and depending on that the array fields will be displayed. I understand ArrayField has a size attribute where I can say how long the array is. Right? So my question is: Is there a way to dinamically change the array size depending on what the admin types in in the "clases" field? I need this to work in the admin app. I am new to django and I'm finding the admin app … -

Django ignore/ disable Invalid HTTP_HOST header
Using sentry for tracking issues with my Django app, I get a lot of reports of the following style: Invalid HTTP_HOST header: 'example.com'. You may need to add 'example.com' to ALLOWED_HOSTS.. As this seems pretty suspicious (if I understand correctly this would mean that somebody poses as my site) I would like Django to disable this entirely. I have a fixed set of ALLOWED_HOSTS and wouldn't want to use up my sentry capacities with this error message. Using nginx on the server I already added the following to my config: if ($host !~* ^(mysite1.com|mysite2.com)$) { return 444; } The error still persists. I also added in Sentry settings "allowed domains" but this only affects the origin and referrer headers not the host header. -
Different Timezones in Django Model
Is there a way to store dates with different timezones in DateTimeField In settings.py, i currently have timezone turned on and set to: TIME_ZONE = 'US/Pacific' When i save date in the model: class DateStore(models.Model): date = models.DateTimeField() the date is automatically converted to US/Pacific zone which is fine, but when i try to save date with timezone set to UTC, those dates are also converted to US/Pacific. I need the timezone info saved and not be replaced with the set timezone in settings.py Note: I already know we can have a text field that stores zone information and then we can localize accordingly, but my question is that can we preserve timezone info from datetime when saving instead of replacing it with saved TIME_ZONE. -
