What is the name of that HTTPS session recorder & playback tool that has an API? Alt. how would you automate an HTTPS website to do user functions?
I've successfully used the tool before. It has a local webpage UI that you goto in your browser that lists the https traffic that occured, and options to play it back. It also comes with a command line tool. I am thinking of a small word ending in "mt", but can't seem to get google to find it. If you can offer any other suggestions that would also be great. Also, would that be an acceptable way to automate an HTTPS session for a website? There's a website I have to automate for a job, and they provide no API to help do the things that users can do on the site, so I am automating from scratch. Thank you for any guidance. I am not allowed to use Selenium webdriver. The code will be hosted on a Django host and the frontend to the automation scripts will be a Django website. -
Tweepy Stream Stop/Start Programatically
I am trying to build a web application using Django to track tweets by hashtags. I am using Tweepy Asyncstreaming and it's working fine. I am new to async programming. I need help with how to stop the running stream and start a new stream when a new hashtag is added. Here is my code: import os from tweepy.asynchronous import AsyncStream import asyncio consumer_key = os.getenv('XXXXXXXXXXX') consumer_secret = os.getenv('XXXXXXXXXXX') access_token = os.getenv('XXXXXXXXXXX') access_token_secret = os.getenv('XXXXXXXXXXX') async def main(): stream = TweetStream(consumer_key, consumer_secret, access_token, access_token_secret) await stream.filter(follow=['web3', 'crypto']) class TweetStream(AsyncStream): async def on_connect(self): print('Stream connected') async def on_status(self, status): if status.in_reply_to_user_id == None and not(status.entities['user_mentions']): print(status.text) print(status.user.screen_name) async def on_error(self, status): print(status) if __name__ == '__main__': asyncio.run(main()) -
How to Search Tags in Wagtail
How do you search wagtail tags? This is my code for my search bar in my webapp: def search(request): search_query = request.GET.get('query', None) page = request.GET.get('page', 1) # Search if search_query: search_results = Page.objects.live().search(search_query) query = Query.get(search_query) # Record hit query.add_hit() else: search_results = Page.objects.none() Tags already have been set up. I tried using this code to make the tags in my model searchable but it didn't work: search_fields = Page.search_fields + [ index.SearchField('select_tags', partial_match=True), ] This is the webpage I looked at: https://docs.wagtail.io/en/stable/topics/search/indexing.html#wagtailsearch-indexing-fields -

Best way to trigger ML model in Django
Hello experienced Django guys, I'm developing my first app in Django with ML model for recommending books. I was wondering what is the most appropriate way to activate the python script clicking the button and taking the value from drop menu. To make it less confusing here is some code example: <!DOCTYPE html> <head> <title>Books</title> <body> <h1>Welcome to books recommender page!</h1> <br> <select> <option disabled = "True" selected>Select your favourite book!</option> {% for books in books %} <option>{{book.name}}</option> {% endfor%} </select> <button>Calculate my recommendations</button> </body> </head> Basically, I've connected Djagno app with Postgre DB with books, created this simple drop menu which shows all data in column. Now I want to pass the selected value to my python ML model (which is executing the function like this): try: print(get_recommendations(selected_book, n=6)) except: print("No book at stock.") Any suggestion how should I pass the drop menu value and trigger the script by clicking the button? -
MultilingualQuerySet always returns empty list
I have a website with support for 2 languages but I have a problem with switching url's. So when user clicks link that leads to some category I get list index out of range my model class Category(models.Model): category = models.CharField(max_length=20,unique=True) def __str__(self): return self.category translations.py for my model class CategoryTranslationOptions(TranslationOptions): fields = ('category',) translator.register(Category, CategoryTranslationOptions) my code view that is responsible for getting product with said category categoryList = Category.objects.all() categoryName = categoryList.filter(Q(category_pl=categorySlug) | Q(category_en=categorySlug)) productsInfo = Product.objects.filter(category=categoryName[0]) What I'm doing in categoryName is looking for name in two languages in case if user switches language mid browsing. Then I get the first value of it because it's a list but the list is empty. update when I printed out categoryList = Category.objects.all().values() I didn't saw any translation-related fields but i can see them in admin panel so it is the case of not getting correct query from database -

How can I make a decorator in models.py?
I have a football Team class in my django Model. I made 3 methods of win, draw and lose where the self.Points_of_the_season will be modified accordingly ( +3 for win, +1 for draw and +0 for lose). But When I wrote those methods, I have to change the self.Match_Played with each call of the 3 methods. How can I make a decorator called @play_match which will add 1 to the concerned field? This is the code of models.py: class Team(models.Model): Team_name = models.CharField(max_length=255) Foundation_year = models.IntegerField() Points_of_season = models.IntegerField(default=0) Match_Played = models.IntegerField(default=0) League = models.ForeignKey(League, on_delete=models.CASCADE) def __str__(self): return f"{self.Team_name}-{self.Foundation_year}" @play_match def win(self): self.Points_of_season += 3 @play_match def draw(self): self.Points_of_season += 1 @play_match def lose(self): pass -

Why is current admin not shown in django app?
I created a mock user profile in Django admin in the admin/auth/user view and assigned the user with all permissions (active, staff status, superuser status). In admin/<app_name>/user I gave the user all authorization permissions. In the Django admin panel, when I hit view site and enter the home view of the django application, the current user is different from the one that was visiting the admin page. Why is the current user different from the admin user? -
Defining view function for displaying postgres data in django
I created the wines database in postgresql (containing ID, names etc), and inserted around 300 observations. I would like to display names of every wine in drop menu with django. The urls.py are properly setted up. App name inside the project is: jacques.

How should I redefine my functions in order to see display in main.html drop menu? -
Celery beat not sending task to worker in heroku, configured in a single dyno in free tier
I am making a website, where the user has to accept an agreement and then an expiration date is set for the user. On that date the contract is supposed to get expired by setting a contract_expired boolean field to True and sending an email to the respective user about the same. I used celery beat for this. Now since the site is in tessting phase, it is hosted in a free tier dyno in heroku, so I had to configure one dyno for web and the other for both celery worker and beat. I scheduled a task for beat where it would run daily on 9 am, to check the exipiries for the users and then do the work as mentioned above. This function was running correctly when I was testing it in the localhost, i.e., by running two seperate terminals for worker and beat. But today at 9 am it did not run in heroku. Below are the codes that i wrote for the entire process procfile release: python manage.py migrate web: gunicorn jgs.wsgi --log-file - celeryworker: celery -A jgs.celery worker & celery -A jgs beat -l INFO & wait -n celery.py from __future__ import absolute_import, unicode_literals import … -
How to use temporary file from form upload - Python Django
I have a form where users can upload up to 1,000 images at a time. I have changed my FILE_UPLOAD_MAX_MEMORY_SIZE in Django settings to 0 so all files uploaded via a form are written to a temp directory in my root folder. I am then trying to process the images with OpenCV. original_img = cv2.imread(temp_image.temporary_file_path()) gray = cv2.cvtColor(original_img,cv2.COLOR_BGR2GRAY) temp_image.temporary_file_path() This returns the absolute file path of the temp image in a string format So I put that in the cv2.imread, however, it creates a NoneType instead of a numpy array like it should and then my program cannot run when it reaches gray = cv2.cvtColor(original_img,cv2.COLOR_BGR2GRAY) How do I read the temporary file into OpenCV? Any help is much appreciated. -
