Сelery starting task every milisecond
Celery task schedule worked fine considerate amount of time. Now one of tasks launches and finishes successfully every couple of milliseconds. Did some search at git/stack and found that some older celery versions suffered from this, but now its fixed.

Calculating fees for smart contracts, such as USDT-TRC20, on the Tron blockchain
I'm currently engaged in a blockchain project, and one of the key components involves the creation of withdrawal transactions. However, I'm facing the challenge of displaying the transaction fee before broadcasting it to the blockchain.

Django Q implement to send periodic emails
I have a Django project with several merchant accounts. When they log in using a URL, a certain view is called that aids with login and authentication. In addition, the same method determines if the merchant's plan expires in a month. If so, the function notifies you by email about the same problem. The problem now is that the view function won't execute if the user doesn't log in, which means he won't get any mail. Can I then have an automatic feature that delivers the mail and verifies each merchant? To notify merchants of their plan expiration even if they don't log in, I want a function in Djnago-Q to run even if the URL is not hit and after a set amount of time. -
Django Custom User Model Admin
In a simple self-training using Django, I'm facing the following problem: 1- I've written a custom user model with two extra fields: phone +fuck 2- I've created a custom admin using custom forms 3- In settings: added AUTH_USER_MODEL = "accounts.CustomUser" where accounts is the app name 1- In admin panel, when trying to add a new user, it doesn't display any of the extra fields and this is a problem, also in the case of editing an existing user. 2- In admin: the last statement is: admin.site.register(CustomUser, CustomUserAdmin) but if i replace it with: admin.site.register(CustomUser), every thing is well and it executed as expected enter image description here [[enter image description here](https://i.stack.imgur.com/qgh3r.png)](https://i.stack.imgur.com/mXrK4.png) -

Automated mail in Django
I have a Django project and multiple merchant accounts when they log in via a URL, a particular view is called which helps in authentication and login. The same function also checks whether the merchant's plan will expire in a month. If yes the function sends an email referring to the same issue. Now the issue is if the user never logs in the view function runs and hence he never receives the mail. So can i have a automated function which checks for every merchant and delivers the mail. I want a function that runs even if the URL is not hit, and after specific time interval, so merchants should be notified about their plan expiry, even if they don't login. -

django rest framework, how to protect my API? [duplicate]
I have an API that uses django-cors-headers to limit its access. This works up to a certain point, however, if I try to make a GET request directly in the browser or using any script, like the requests library for example, I can get a response with status 200 and with all the data from the endpoint. How can I protect my API so that it cannot be accessed by anyone? I tried configuring django-cors-headers in different ways, but it doesn't work. -

Using Mezzanine (Django) and updating to django 5.0 : I get "TypeError: QuerySet._clone() got an unexpected keyword argument '_search_terms'"
I'm installing mezzanine vie netbsd packages because I found that's the easiest for netbsd. I'm stuck on the following error message. I've found great answers for every other upgraded code like modules that have changed. I am consulting the django docs, but I thought I'd start by asking in this forum how to change the code to give the right search terms. I assume that changinge mezzanine/core/managers.py is the way to go. I've used mezzanine for a long time and hope that it gains new life. An anecdote: I got hired to manage an electric assist cargo bike company for a home valet compost service and I found that the management used mezzanine(django) for their website. When I asked about contributing to the website, the young snobs snubbed me without giving me a chance. but anyway: TypeError: QuerySet._clone() got an unexpected keyword argument '_search_terms' I haven't tried anything here other than researching the source code. I will keep exploring it. -
How can I access foreign key methods in a Django model?
I have a table Product which contain only the price of the products and a table Discount which contains the percentage of the discount associated to the products. I want to access the function apply_percentage in the final_price method. In the real code I have different type of Discount for each product, the situation explained is a generalization to let you understand the problem. This is my models.py file: class Product(models.Model): price = models.FloatField("Price") def final_price(self): **return apply_percentage(self.price)** class Discount(models.Model): percentage = models.FloatField("Percentage") product = models.ForeignKey(Product) def __str__(self): return self.percentage def apply_percentage(self, price): return (price - (price*self.percentage)) I use Django (4, 1, 12, 'final', 0) with Python 3.10.12.
