Write a program to help the manager to find out the employee of the week [closed]
There is a family consisting of a husband-wife from Stone Age. Every day, the husband goes fishing in the sea and brings a certain number of fishes for food at the end of the day. The mood of the wife i.e.to be happy or sad depends on the number of fishes' husband brings back home. Everyday wife updates record of 'max' and 'min' fishes husband caught. She gets happy only when the husband brings more fishes than 'max' of the all the previous day and gets sad when he brings fewer fishes than 'min' of the all previous day. Write a program to predict the overall happiness of the wife with her husband. Create your own logic to define the "overall" happiness and clearly state your assumptions. Sample Input: 9 10 5 20 20 4 5 2 25 1 Sample Output: You can show output in your own way. But output should represent Happiness. It may be in percentage or count of happiness and sadness. Explanation: As the husband caught less fish than his all past fishing records for 4 days and caught record- breaking fish for 2 days. Hence 4 - 2 = 2 is overall happiness (difference of … -
What is the best approach to use cache in Django?
I have a GET and POST request in a Django APIView. from rest_framework.response import Response from rest_framework.views import APIView from rest_framework import status class DemoView(APIView): def get(self, request): user_id = request.query_params.get('user_id', None) num = MyModel.objects.get(id=user_id).num for i in range(num): num = num*i + 1. # In real work, much more complicated. return Response({'success': True, 'square':num}, status=status.HTTP_200_OK) def post(self, request): user_id = request.data.get('user_id', None) num = request.data.get('num', None) num_from_my_model = MyModel.objects.get(id=user_id).num if num == num_from_my_model: MyModel.objects.filter(id=user_id).update(num=num) return Response({'success': True}, status=status.HTTP_200_OK) The problem is in my real work, GET method may need a long time(about 10 seconds) to finish. Here is how I do it: (1) First of all, I create a database MyCache to see if num has changed in POST method. (2) If changed, MyCache will turn the cache_changed parameter to True(default False). (3) In GET method, I will check if cache_changed is True. If True, I will save result into cache. If False, I will get result from cache. from rest_framework.response import Response from rest_framework.views import APIView from rest_framework import status from django.utils.decorators import method_decorator from django.views.decorators.cache import cache_page from django.core.cache import cache class DemoView(APIView): @method_decorator(cache_page(60)) def get(self, request): user_id = request.query_params.get('user_id', None) cache_changed = MyCache.objects.get(id=user_id).cache_changed if cache_changed: num … -

Django ImageField is not being updated while submiting a form
Issue describrion I have a model which describes a UserProfile and a dedicated form to allow user to update the model. Except photo(ImageField), everything is working fine. Issue with photo field is that the image is not being changed at all with EditProfileForm. In other words I have same image attached to this field before and after form submition, the photo is pointing to the same picture, and nothing new was uploaded to the server. It is worth to be noted that photo field is working through the form from admin panel.

(1062, "Duplicate entry '' for key 'email'") and (1062, "Duplicate entry '' for key 'phone'") in Django

Implementing Django Bootstrap crispy forms into default signup / login pages?
I've set up user account signup and login pages following this tutorial and it all works great, except the pages have no formatting. I'm now looking for a simple drop in solution to improve the appearance of "templates/registration/login.html" and "templates/registration/signup.html". Someone recommended crispy forms which look great, and as the rest of my site uses Bootstrap 5, crispy-bootstrap5 looks ideal. I'm struggling to implement crispy-bootstrap5 as I don't understand Django's inbuilt django.contrib.auth.forms nor forms in general, and can't find simple reproducible examples for crispy forms with signup.html and login.html. I've installed packages fine, but now don't know how to beautify login.html and signup.html from that tutorial: {% extends 'base.html' %} {% block title %}Sign Up{% endblock %} {% block content %} <h2>Sign up</h2> <form method="post"> {% csrf_token %} {{ form.as_p }} <button type="submit">Sign Up</button> </form> {% endblock %} I don't know where to go with this, but the docs for regular django-crispy links to a gist for an eg form, and the index.html {% load crispy_forms_tags %} and {% crispy form %}.

Why does assigning value to Django Object change the value from NoneType to Tuple?
I am polling an API and I am returned a dictionary.
