Multithreaded undetected chromedriver issue
I currently coded a scrapping function that works in my django web app and is hosted on Heroku, the scrapping function works through Celery and uses Undetected_ChromeDriver. The main issue is that there seems to be a problem when running the driver through multithreaded code because the code acts this way : Let's say I have 2 urls to scrap, the code is set to scrap this way : results = [] # Create a ThreadPoolExecutor with 10 workers with ThreadPoolExecutor(max_workers=10) as executor: # Assign tasks to each worker using the executor.submit method futures = [executor.submit(scrape_website, website, info, product_name) for website, info in websites.items()] # Wait for all workers to complete their tasks and retrieve their results for future in as_completed(futures): results.extend(future.result()) return results The code is set to open drivers this way : def create_selenium_instance(): options = uc.ChromeOptions() options.binary_location = os.environ.get("GOOGLE_CHROME_BIN") options.add_argument('--headless=new') options.add_argument('--no-sandbox') options.add_argument("--disable-gpu") options.add_argument("--disable-dev-shm-usage") options.add_argument("--disable-background-networking") options.add_argument("--disable-background-timer-throttling") options.add_argument("--disable-renderer-backgrounding") options.add_argument("--disable-sync") options.add_argument("--metrics-recording-only") options.add_argument("--disable-default-apps") options.add_argument("--mute-audio") options.add_argument("--no-first-run") options.add_argument("--disable-breakpad") chromedriver_path = os.environ.get("CHROMEDRIVER_PATH") renamed_path = "/app/.local/share/undetected_chromedriver/undetected_chromedriver" driver = uc.Chrome(executable_path=os.environ.get("CHROMEDRIVER_PATH"), options=options) return driver The code is able to open the first URL and retrieve the correct informations (they get printed out in the logs) but as soon as it tries to open the second URL i … -

Data Structure Serialization (Django)

Is there anyway to deploy 2 django projects using docker having different domain?
I am new to programming world, so basically an average. Since few days, I am beating myself up in order to deploy 2 django projects having different domains with docker, uwsgi and Nginx but somehow I could not. Problem 1: I cant run 2nd nginx docker using port 80. Getting an error of port already in use. Problem 2: If I change the ports and run the app docker and nginx. It doesnt work. Both the domains pointing to Nginx at port 80. As per nginx logs. Problem 3: One domain that is mentioned in allowed hosts of django settings, works fine. And other domain throws a bad request error. Same thing on Vice-versa. I have read multiple articles saw multiple posts and videos still no help. So Ends up deploying the projects directly on the server using nginx and uswgi. I like the docker technology but had to stop it. There's not much relevant topics available in internet. So asking here with minimum to no hope. Am I missing something? Any points and help relevant to this topic would be appreciated? Thanks in advance -

AWS SES: AccessDenied when calling SendRawEmail - User is not authorised to perform ses:SendRawEmail on Resource
Alright, this is the moment I'm completely freaking out. And it is probably something small I'm missing out on, but I'm stuck for almost 2 days at the moment. I'm trying to send an email via SES, I'm already out of sandbox mode. Whenever I log in on AWS and try to send an email via the 'Send test Email' button, everything works fine. If I use Boto3/django-ses library, I get the Permission Denied error, same user, a different way of performing the action. The user has the following policies attached: { "Version": "2012-10-17", "Statement": [ { "Effect": "Allow", "Action": "*", "Resource": "*" } ] } & (because I got trust issues) { "Statement": [ { "Action": [ "ses:SendEmail", "ses:SendRawEmail" ], "Effect": "Allow", "Resource": "*" } ], "Version": "2012-10-17" } && Because I got even more trust issues I also attached an Authorization policy to the SES verified identity: { "Version": "2012-10-17", "Statement": [ { "Sid": "stmt1682154101077", "Effect": "Allow", "Principal": { "AWS": "arn:aws:iam::FOO:user/BAR" }, "Action": [ "ses:SendEmail", "ses:SendRawEmail" ], "Resource": "arn:aws:ses:eu-central-1:FOO:identity/no-reply@example.com", "Condition": {} } ] } Which part am I missing to give the user permission to send email not via the AWS Console but via the Library? -

Getting Similarly-Named Keys from Redis Cache on Django web app
I am currently having trouble trying to cache a large Pandas DataFrame (300,000+ rows) that has 3 columns, an ID column and 2 large numpy array columns. I am unable to cache the whole DataFrame as one object since it is so large. So, I thought to cache by number, break up the DataFrame, and load them back in as chunks. The number of rows in the DataFrame increase daily, so I will never know how many chunks of rows are cached. Therefore, I save them as 'encodings_df_1', 'encodings_df_2', ..., 'encodings_df_n'; where n is the highest number needed to cache all chunks of the original DataFrame. Is there a way to get all the keys where it is like 'encodings_df_*', or is there an easier way to cache and load the original DataFrame back in? EXAMPLE: # Let's say the Pandas DataFrame 'df' currently has a length of 350 #I should have 4 objects cached in my Redis db: # encodings_df_1, encodings_df_2, encodings_df_3, and encodings_df_4 # initial vars chunk_size = 100 number_of_chunks = math.ceil(len(df) / chunk_size) # upper and lower bounds for DF segmentation lower = 0 upper = lower + chunk_size # loop to cache DF chunks for n …
