What is the best django practice to collect and store users' interest data?
I need to implement the simpliest users interest module in Django. I have a very small web application with the ony search bar and a button. The search bar is intended for an account number input. After pressing the button users get information about the entered account number I need to collect and store data of users' interest by days. How many times data was searched everday. eg. | day |number of queries| |22 Oct | 7 | |23 Oct | 5 | ... Django 2.2.1 I created the model: models.py class LeadsNumber(models.Model): date_of_interest = models.DateField(blank=False) number_of_queries = models.IntegerField(blank=False, default=0) class Meta: ordering = ["date"] When the user input the data and press the button the function from view.py look for the existing model and then update or create a new instance of the LeadsNumber model for the day when the account number was searched. I guess there is a better way for implementing such thing. Share your thoughts please -

Trying to Write a Django Query That Counts Events Per Day For Events That Span Multiple Days
I am using Django and trying to count the number of events that are running on each day based on events running across multiple days. For example, if Event 1 starts on Monday and ends on Wednesday and Event 2 starts on Tuesday and ends on Thursday, the event count per day should be: Monday (1 event), Tuesday (2 events), Wednesday (2 events), Thursday (1 event). The event model looks like this: class Event(models.Model): name = models.CharField(max_length=300, blank=True) start_date = models.DateTimeField(blank=True) end_date = models.DateTimeField(blank=True) def __str__(self): return self.name I would like to get query results to include the date of the day we are counting for, the number of events running on that day, and the name of each event running on that day. Any help on this Django query would be helpful. Thanks in advance! -

ModuleNotFoundError: No module named 'project.appname' when running Django tests
When trying to run my tests using either ./manage.py test or pytest, all of the apps in my Django project fail their tests with ModuleNotFoundError: No module named 'project.appname'. However, when running with ./manage.py test app.tests (if the tests are in a dedicated tests directory), they do progress beyond a Module Not Found error. I think there is something wrong with my configuration that leads to this error but I have no idea where to poke to try fixing this: I'm not seeing anything that makes PyCharm yell at me when I look at any testing module nor when looking at Settings.py -
Stripe Payment Intent API Prevent Form From Submitting Until User Authenticates Card
Using the new Stripe Payment Intent API and Stripe.js, I want to be able to do the following: 1) If the user's card is valid but requires authentication (SCA), do not submit the form until the user clicks "complete authentication" on the 3D secure popup. 2) If the user's card is valid but does not require authentication (SCA), submit the form. Here is a video of my issue: https://streamable.com/797e5 As you can see from the video, the form submits itself with a card that requires authentication but the user does not have time to click "complete authentication" since the form refreshes the page immediately. Stripe support says JavaScript is needed to do this and provided me a PHP example. https://glitch.com/edit/#!/stripe-php-sca-example?path=public/charge.php:9:0 However, I am using Django and not PHP. I am also not sure how to code this in JavaScript. Any help would be greatly appreciated.

Is there any approach like saving the data in memory during computation or global variables so that it can be accessed anywhere in the views.py. -

save the data in the database by editing the table info - Django
I have a page "EditStudent" that display all absentee's name. This page allows the admin to change their status from absent to present or vice versa, add remarks if needed. The information displayed in the page involved two models. Namelist model.py: Contains all the students information such as studId, studName and more.

Saving user data and selecting one instance later on
I am working on a project that requires an image gallery for a website that I am making. I have already made the image upload models and uploaded a couple of images to the server media root. However, I am a newbie in django and can't for the life of me figure out the following problem: The admin should be able to upload images into the server. The admin interface must expose a selector that enables a user to select among the uploaded images to be shown on the website. Among the uploaded images, only one can be selected. In short, I need to store configuration settings from user side on the server but allow only one instance. How can I start? -

Errors running django tests after python 2/3 upgrade, unittest.loader._FailedTest
I'm helping my group upgrade their application from python 2 to 3, and am running into errors with the unit tests. When I run the tests with python3 manage.py test groupapp --settings=settings.deploy_dev I get the errors below. But if I run with python3 manage.py test groupapp.tests --settings=settings.deploy_dev the errors do not occur. Its worth noting that these errors occur even after I deleted all our tests from the tests folder, and as far as I can tell they aren't connected to an actual test case. I don't understand the difference between these two calls in python 3. In python 2 if I run the two calls I get the same result (no test failures). groupapp_v2.groupapp.admin (unittest.loader._FailedTest) ...

Django - Suspending/deactivating an account for N amount of seconds
In my Django application, If the user enters the wrong password more than 7 times, then I want to suspend/deactivate their account for 10 seconds. I perform an If statement to see if the wrong password has been inputted more than 7 times, and that works fine. Inside the if statement, I want to set user.is_active to False so they cannot login for 10 seconds. After 10 seconds has passed, I want user.is_active to be set back to True so they can attempt to login again. How would I implement this functionality? Thank you.
