海外TECH	DEV Community	Daily Share Price Notifications using Python, SQL and Africas Talking - Part Two	https://dev.to/ken_mwaura1/daily-share-price-notifications-using-python-sql-and-africas-talking-part-two-37db	Daily Share Price Notifications using Python SQL and Africas Talking Part Two Previously To recap abit in Part One of this article Created a folder to hold all of our code Used pip to install the required packages including africastalking beautifulsoup scrapy psycopg binary sqlachemy python dotenv Created our first project and spider using scrapy cli Scraped the afx website for stock prices We followed that by cleaning the data removing html tags and unnecessary styling Finally we defined our data pipeline as required by scrapy and database parameters This was enable data to be insterted and therefore persisted across different sessions We ran our scraper to ensure everything is working as it should We also saved the scraped data as a JSON file for quick preview For this article we will cover creating a SMS notification script once a certain stock reaches a specified price threshold This will be enabled by Africas Talking SMS api through the python SDK To wrap up we ll deploy our project to a heroku server and it have run The full code for this tutorial is on github NotificationsIn this section we ll create a script that queries the database retrieves a specified stock price checks against set constraints and if the specified condition is met a notification text is sent Our current file structure is as shown below python projects tree nse scrapernse scraper├ーLICENSE├ーnse scraper│  ├ー init py│  ├ーitems py│  ├ーmiddlewares py│  ├ーmodels py│  ├ーpipelines py│  ├ーsettings py│  ├ーspiders│  │  ├ーafx scraper py│  │  └ー init py│  └ーtest json├ーREADME md├ーrequirements txt├ーscrapy cfg└ーtest json directories filesInside the nse scraper nse scraper folder lets create a stock notification py file This will hold all of query and notification code Inside add the following code stock notification pyfrom typing import List Anyfrom models import StockData db connectfrom sqlalchemy orm import sessionmakerfrom sqlalchemy import descimport africastalking as atimport osThe above block code imports our required libraries ranging from africastalking python sdk to the os package We also import the required classes Stockdata and db connect from models py file We also import the List and Any objects fron the typing library For the next part ensure you have an Africas Talking account and a Heroku account stock notification pyat username os environ get at username at api key os environ get at api key mobile number os environ get mobile number print at username at api key Initialize the Africas sdk py passing the api key and username from the env fileat initialize at username at api key sms at SMSaccount at ApplicationThe above code retrieves the required credentials from enviroment variables Usually I prefer to use env files however since we are deploying to Heroku We need to specify environment variables that we will define in Heroku We the initialize the Africas Talking Sdk using our appropriate credentials We further assign the SMS class to a variable We also assign the Application class to a account variable The snippet below assigns engine variable to the db connect function following it up by binding sessionmaker to the engine variable This implements a session when doing database operations We finally define an empty ticker data list to hold all of our stock data stock notification pydef stock query sq session query StockData id StockData stock ticker StockData stock name StockData stock price filter StockData stock ticker SCOM for id ticker name price in sq order by desc StockData id limit print id name ticker price new data stock id id stock name name stock ticker ticker stock price price return new dataWe define a stock query function to query our specific stock data We then define a query for the database using our pre defined StockData class we are checking specifically checking for the latest Safaricom PLC stock data This is however just for demonstration purposes you are free to choose any other stock or counter We then unpack the returned data into the new data dictionary stock notification py Create a function to send a message containing the stock ticker and pricedef stock notification message str number int try response sms send stock data number print account fetch application data print response except Exception as e print f Houston we have a problem e In the snippet above we create a stock notification function and pass stock data argument specified as a list We also pass a number argument of the integer type As the name suggests this function will effectively send a text message to the us once a stock reaches a certain criteria We throw in a try catch block this ensures incase the message fails to send we have a way to catch and debug the error We also output our account balance inorder to ensure we get a balance check on each run stock notification py message f stock query stock name is now Kes stock query stock price per share check if Safaricom share price is more than Kes and send a notification if stock query get stock price gt Call the function passing the message and mobile number as a arguments print message stock notification message mobile number In the final block of code above we define a message variable to hold the data we ll send as a text message We want to send the stock name and the current stock price We then define the criteria inorder to send the message in this case its when the price is above Kes When the criteria is achieved the stock notification function is called To recap your project should now look as shown below nse scraper├ーLICENSE├ーnse scraper│  ├ー init py│  ├ーitems py│  ├ーmiddlewares

json directories files Deployment Lets now deploy our scraper to Heroku and have it run in one hour intervals Heroku account registrationFirst and foremost you would need to register an account with Heroku it s free Installing Heroku CLIAfter your account registration let s use Heroku CLI to create and manage our project You may check out the installation steps for other OS here for arch linuxsudo pacman S heroku LoginTo log in using Heroku s CLI simply cd to your project folder and run heroku login cd nse scraper heroku login heroku Press any key to open up the browser to login or q to exit Opening browser to xxxx xxxx xxxxLogging in doneLogged in as amp gmail com GitAt this stage you should already have set up your project with git init and git commit etc The next steps are to turn your project into a git repository and push it to Heroku i To create a Heroku application heroku apps create daily nse scrape ii Add a remote to your local repository heroku git remote a daily nse scraper iii Deploy your code git push heroku mainOnce we re done here let s open up our Heroku dashboard page for your newly created Heroku application Setup free tier managed PostgreSQL service on HerokuTake note that the free tier only has a limit of rows at the time of writing this This step is fairly simple simply go to the Resources tab on your Heroku dashboard and look for Heroku Postgres select the free tier or whichever you deem fit To look for your database credentials simply click on your Heroku Postgres add on →select Settings → View Credentials Finally adjust your Scrapy project s connection to your database accordingly settings py POSTGRES SETTINGShost os environ get POSTGRES HOST port os environ get POSTGRES PORT username os environ get POSTGRES USER password os environ get POSTGRES PASS database os environ get POSTGRES DB drivername postgresql DATABASE f drivername username password host port database Or alternatively DATABASE CONNECTION STRING postgres xxxx xxxx ec xx xxx xxx xx compute amazonaws com xxxxxxEnsure you add your configuration variables in Settings → Reveal Config Vars This will allow Heroku to get and set the required environment configuration for our web scraper to run As shown belowEnd ResultsBy the end of this if you were to visit your Heroku dashboard activity feed you should see your application there where the latest activity says that your app has been deployed If you try to run heroku run scrapy crawl afx scraper on your local terminal you should see that it will attempt to run the crawler on your Heroku server If everything ran as expected You should see output on your terminal In the database addon we can run a simple query to check our database tables Note I also added a runtime txt file at the root of our project this tells Heroku what python version to use for our project By default it uses the latest python version this may introduce errors during execution thus its better to opt for a fixed version In this case I specified python Heroku SchedulerThis section of the article shows you how you can run your crawlers spiders periodically Though Heroku offers several different schedulers that could run your application periodically I personally prefer Heroku Scheduler as it has a free tier and it is super simple to use To use the free tier of this add on Heroku requires you to add a payment method to your account ConfigurationInside your newly added Heroku Scheduler add on simply select Add Job on the top right corner and you should see the screen as shown in the picture beside To run thescrapy crawl afx scraper command periodically simply select a time interval and save job How do I schedule a daily job Simply configure our Heroku Scheduler to run our python script every day at a specified time In our case its every hour at minutes Then it should run our command scrapy crawl afx scraper Scheduling Text NotificationsNow we need add a scheduler for Heroku to run our notifiction script which will inturn send us texts Since we already have an instance of Heroku running in our app we need an alternative Advanced scheduler is a good option as it offers a free trial and if need be a per month for an upgrade Setup Inside our daily nse scraper app search for the advanced scheduler addon Select the trail free plan and submit order form ConfigurationClick on the Advanced Scheduler addon Inside the overview page Click on Create trigger button The free trial allows up to triggers We ll set a trigger for am each day specify the command python nse scraper stock notification py to run Remember to select the correct timezone in my case its Africa Nairobi and save the changes TestingTo ensure the scheduler will execute as expected We can manually run the trigger on the overview page click on the more button and select execute trigger You should now have received a notification text if everything went as expected Wrap Up To wrap things up I have found a lot of success in deploying and running my spiders periodically with this method The only downside here is the free tier version of Heroku Postgres which only supports up to database rows In this case we can easily opt in for the paid version of it and scale our database accordingly based on our demand On a side note we could also easily swap out our Scrapy project s database instance to use another cloud RDS solution such as Amazon RDS On top of these you can also easily opt in for other available Heroku add ons for logging and monitoring purposes Another Free Alternative MethodWhile I am aware that we could use Scrapyd to host your spiders and actually send requests alongside with ScrapydWeb I personally prefer to keep my scraper deployment simple quick and free If you are interested in this alternative instead check out this post written by Harry Wang If you have any question or comments Let me know in the comments or on Twitter Happy Coding	2021-05-30 10:17:30
