Django rest delete request error "The 'file' attribute has no file associated with it. "
I am using the Django rest framework for the API. I tried to make the file field optional. When I create the instance, it works properly, i.e., I can upload my data without a file. But when I tried to delete it, it shows the following error, The 'file' attribute has no file associated with it. In models.py file, I write as below, file = models.FileField(upload_to="%Y/%m/%d", null=True, blank=True) In serializer.py file, I write as below, class DataSerializer(serializers.ModelSerializer): file = serializers.FileField( required=False, allow_empty_file=True, allow_null=True) class Meta: model = DataIndex fields = '__all__' Can anyone please help me to solve this error? Thanks in advance. -
set command in windows not working for django SECRET_KEY | django.core.exceptions.ImproperlyConfigured: Set the SECRET_KEY environment variable
I set the SECRET_KEY with set command in the terminal, but nothing works set SECRET_KEY='9l=jjp#g0-mbdfsntqww91s9b^a!kj44ljl4f5h!+uoft' settings.py: from pathlib import Path import environ # Build paths inside the project like this: BASE_DIR / 'subdir'. BASE_DIR = Path(__file__).resolve().parent.parent env = environ.Env( DEBUG=(bool, False) ) READ_DOT_ENV_FILE = env.bool('READ_DOT_ENV_FILE', default=False) if READ_DOT_ENV_FILE: environ.Env.read_env() DEBUG = env('DEBUG') SECRET_KEY = env('SECRET_KEY') ALLOWED_HOSTS = [] .env: SECRET_KEY='9l=jjp#g0-mbdfsntqww91s9b^a!kj44ljl4f5h!+uoft' DEBUG=True So as you can read, the READ_DOT_ENV_FILE should be True to let django read the system variables from .env file, otherwise, it'll read the variables from the terminal (session) by defining them in it using the set command. In this case: set DEBUG=True set SECRET_KEY='9l=jjp#g0-mbdfsntqww91s9b^a!kj44ljl4f5h!+uoft' -
How to format index pagination url format django
Question is really similar to Django sitemap index pagination URL format but i didn't get the answer. So, i need my url to be like this /sitemap-products-3.xml, where 3 is page by paginator. My current working links: sitemap-products.xml?p=3 . It's was generated by generic function (index). I did some work, and links look like sitemap-products-3.xml , but in urls.py, I don't know how to pass number of page in paginator, cuz the link gives me 404.

How to have shared related name?
I am trying to create a model to represent travel time between two venues, so it has two foreign keys to the Venue model: class VenueTravel(models.Model): venue1 = models.ForeignKey('Venue', related_name='travel_times') venue2 = models.ForeignKey('Venue', related_name='travel_times') minutes = models.IntegerField(default=0, validators=[MinValueValidator(0)]) class Meta: unique_together = ('venue1', 'venue2') However, I'm having trouble making the migration for this model because the related name clashes for both fields. Usually, I would understand why, but since in this case the related object relation back to this object represents the same for both fields (all travel distances for the venue, no matter if it's venue1 of venue2), I don't really care about naming them differently. In fact, I'd want to name them the same. Is there any way I could do that? If you think there's a better way of modelling this use case, please feel free to make your suggestion. -

Django migration passed but field did not get deleted
I have a django application in production, last week I wanted to delete a field from my user model, review_rate, to replace it by a M2M relation with another table.

I have table with 3 columns and rows will be added dynamically depending on of subjects count. 1column is label and others 2 are input fields. How would I get table data after post, into views.py function ? Html table <form method="POST" action= "{% url 'save_report' %}"> {% csrf_token %} <table id="myTable"> <tr> <th> SUBJECTS </th> <th> Full Marks</th> <th> Marks OBTAINED</th> </tr> {% for subject in subjects %} <tr> <td> <label type="text" id="a" name="a"> {{subject.subject_name}}</label></td> <td> <input type="number" id="b" name="b"/></td> <td> <input type="number" id="c" name="c"/></td> </tr> {% endfor %} <button type="submit" onclick= "{% url 'message_page' %}" name="save" id="save">save </button> My views.py def save_report(request): if request.method=="POST": Full_marks= request.POST.get("b") Print(Full_marks) #check Obtained= request.POST.get("c") Print(Obtained) #check else: Do Stuff Here in save_report() function in views.py I'm getting only last entered value of the input field. I'm trying to save table inputs into database as it is. Any guidance is appreciated. Please..
