Selecting serializer field in the DRF browsable API
For example my model and its serializer: class Person(models.Model): name = models.CharField(max_length=150) age = models.IntegerField() city = models.CharField(max_length=150) class PersonSerializer(serializers.ModelSerializer): class Meta: model = Person fields = '__all__' # to select these fields on the browsable API So my aim is to select serializer fields dynamically in order to post on the browsable API. I thought about adding a filterset class with a MultipleChoiceFilter field for serializer field names. class PersonFilter(filters.FilterSet): FIELD_CHOICES = ( (0, 'name'), (1, 'age'), (2, 'city'), ) field = filters.MultipleChoiceFilter(label='fields', choices=FIELD_CHOICES) class Meta: model = Person fields = ['field'] What I try to do is: Selecting the fields from the json query: { "name": "Jack", "age": 30, "city": "London", }, by using the filter on the browsable API : obtaining the subset of fields: { "name": "Jack", "city": "London", } At this point I couldn't find out how to manipulate the serializer fields variable from the filterset class. Also I don't know if it's a good practice to do it or there's a simpler way. -

Auto increment rank field in my response in Django Rest Framework

Why I am not getting images from django model in correct ways?
I have created a model in which there are many fields, one of which is the picture field. When I am storing the data from the admin panel the images are stored with the correct address in the database but when I am storing the images from an HTML form they are stored with another address so I am missing the images in my template. Here is my model in Django: class User(AbstractUser): picture = models.ImageField(upload_to='profile_pictures', null=True, blank=True) full_name = models.CharField(max_length=100, help_text='Help people discover your account by using the name you\'re known by: either your full name, nickname, or business name.') email = models.EmailField(blank=True) # Optional fields bio = models.TextField(null=True, blank=True, help_text='Provide your personal information, even if the account is used for a business, a pet or something else. This won\'t be a part of your public profile.') website = models.URLField(null=True, blank=True) phone_number = models.CharField(max_length=20, null=True, blank=True) gender = models.CharField(max_length=10, choices=GENDER_CHOICES, null=True, blank=True) is_private_account = models.BooleanField(null=True, blank=True) first_name = None last_name = None USERNAME_FIELD = 'username' REQUIRED_FIELDS = ['full_name'] objects = CustomUserManager() def __str__(self): return self.email Here is the HTML form that I am using to store the data from the user: <form action="posts" method="POST"> {% csrf_token %} <input type="text" … -
How can I add a changeable "subfield" to a ModelField in django?
I'm trying to create a kind of "subfield" for a CharField in django, but I'm not sure (a) if it is possible at all and (b) how to succeed if it is indeed possible. Let's say I want a model for Tools. They would have a, e.g., a field for long_name, short_name, maybe a ForeignKey for realizing different departments. One of these tools I'd like to be a Link, the said "subfield" being a URLField with the href to the webpage. Now, I can create multiple link entries with the associated URL, but I'd rather have only one tool called "Link" with the changing URL attached. Is this a case for ForeignKey as well? Does it make sense to have a model with only one field (well, two if you count the pkid) in it? Or am I on a completely lost path here? Any guidance is appreciated. -

Store user input using forms or models in Django?
I have a Django ML web app where the user inputs some values and the ML models calculates a value and return it. What I want to do is save those values entered by the user and later use those values to retrain the ML model. Basically the user input should be saved in the database and later I should be able to fetch it for retraining. I have a couple questions regarding this: 1.) Should I use forms for saving user input or should I use models? 2.) What is the difference between using forms or models for saving user input? Any links/material/tutorial would be appreciated! Thanks! -

Django Consecutive Days and Max Consecutive days Query
I have a following model. class CategoryModel(BaseModel): name = models.CharField(max_length=100) icon = models.ImageField(upload_to=upload_icon_image_to) description = models.CharField(max_length=100) user = models.ForeignKey(User,on_delete=models.CasCade) def __str__(self): return self.name The basic idea is that whenever a user added a category In one day whether being 1 or 20 records it is regarded as 1 streak and if the user again adds a new category then it is regarded as a +1 streak so current streak will be 2 and max streak is also 2 if user consecutively adds for 5 days streak is 5 days as it is max streak. I just want to display as { "current_streak":3, "max_streak":12 } here current streak is 3 but previous streak set was 12 so it regarded as max streak Any Idea how I can achieve this query? -

cloudinary won't upload image in browser and shows empty image box
I'm supposed to upload images using cloudinary in my django app, but they won't upload in the browser. I can upload them from admin perfectly fine, though. The problem is my 'choose file' button lets me choose an image, but it won't display in my browser. And when I make a post, whether its a regular post or one with a picture, an empty box shows up and I can't get rid of it. I'll attach a screenshot for reference and show my code. Sorry if my explanation is confusing, I'm still new. <input type="file" id="img-select"> <script src="static/js/file.js"></script> <script> const imgInput = document.querySelector('#img-select') const imgPreview = document.querySelector('.preview') const pickerBtn = document.querySelector('.upload') imgInput.addEventListener('change', function() { const file = this.files[0] if(!file) return const reader = new FileReader() reader.addEventListener('load', function() { imgPreview.src = this.result }) reader.readAsDataURL(file) }) </script> screenshot for further info, that image was uploaded through admin. and that empty box towards the bottom of the screen is what I'm having trouble with -
