I'm a Graduate student at UT Arlington. I always feel that taking care of both physically and mentally are essential to our success. So, I start my daily routine at Fitness Recreation Center (gym) and registering slots daily is a hassle and due to covid the gym slots are very limited and I don't want to miss them.

So I have written a python script that automatically registers my gym slot every day

Creating and Deploying a python script on Heroku.com

Prerequisites:

  • Python
  • Selenium
  • webdriver (I used Chrome webdriver)

Let's Begin:

Step 1 :

import all necessary modules

from selenium import webdriver
from selenium.webdriver.common.keys import Keys
from time import sleep
from os import environ

Step 2:

Enter the location of Chrome Webdriver and assign it to the browser variable

browser=webdriver.Chrome("/Users/sunilaleti/Documents/chromedriver")

Step 3:

There are few steps to register, i.e opening the portal, authentication(email and password) and slot booking.

we have broswer.get() to open the webpage and for the authentication steps we need to grab the XPath of that element

To grab Xpath of an element: inspect >> copy >> copy Xpath

# to click on sign in button
browser.find_element_by_xpath('//*[@id="divLoginOptions"]/div[2]/div[2]/div/button').click()

# to enter my email for authentication
browser.find_element_by_xpath('//*[@id="i0116"]').send_keys(environ.get["Email"])
browser.find_element_by_xpath('//*[@id="idSIButton9"]').click()

# to enter my password
browser.find_element_by_xpath('//*[@id="i0118"]').send_keys(environ.get["Password"])

# to click on submit
browser.find_element_by_xpath('/html/body/div/form[1]/div/div/div[2]/div/div/div[1]/div[2]/div[2]/div/div[2]/div/div[3]/div[2]/div/div/div/div/input').click()

# to scroll the window
browser.execute_script("window.scrollTo(0,document.body.scrollHeight)")

# to book gym slot
browser.find_element_by_xpath('//*[@id="divBookingSlots"]/div/div[1]/div/button').click()

Source Code:

from selenium import webdriver
from selenium.webdriver.common.keys import Keys
from time import sleep
from os import environ


def Booking():
     browser=webdriver.Chrome("/Users/sunilaleti/Documents/chromedriver") #Enter Location of Chrome driver
    browser.maximize_window()
    try:
        browser.get("https://reclink.uta.edu/booking/5dcc386e-4bd5-4474-80ec-a47472d3963a")
        sleep(2)
        browser.find_element_by_xpath('//*[@id="divLoginOptions"]/div[2]/div[2]/div/button').click()
        browser.find_element_by_xpath('//*[@id="i0116"]').send_keys(environ.get["Email"])
        browser.find_element_by_xpath('//*[@id="idSIButton9"]').click()
        sleep(2)
        browser.find_element_by_xpath('//*[@id="i0118"]').send_keys(environ.get["Password"])
        sleep(2)
        browser.find_element_by_xpath('/html/body/div/form[1]/div/div/div[2]/div/div/div[1]/div[2]/div[2]/div/div[2]/div/div[3]/div[2]/div/div/div/div/input').click()
        browser.execute_script("window.scrollTo(0,document.body.scrollHeight)")
        browser.find_element_by_xpath('//*[@id="divBookingSlots"]/div/div[1]/div/button').click()
        print("Booked Successfully")

    except:
        print("Booking Failed")

    finally:
        browser.quit()

if __name__ == '__main__':
    Booking()

Step 4:

We have written our python script, now we should deploy this on Heroku (which is a container-based cloud Platform as a Service (PaaS)). Developers use Heroku to deploy, manage, and scale modern apps.

For deploying this python script, we also need a Procfile and requirements.txt file. Push these files to GitHub and connect to it Heroku

You can get these files from my GitHub repo

And in order deploy selenium script in heroku, we need to add these in our code

chrome_options = webdriver.ChromeOptions()
chrome_options.binary_location = os.environ.get("GOOGLE_CHROME_BIN")
chrome_options.add_argument("--headless")
chrome_options.add_argument("--disable-dev-shm-usage")
chrome_options.add_argument("--no-sandbox")
browser = webdriver.Chrome(executable_path=environ.get("CHROMEDRIVER_PATH"), options=chrome_options)

Add these values in Config Vars Screen Shot 2021-03-27 at 5.37.31 AM.png

Step 5:

Add Heroku Scheduler add-on to schedule this python script to execute everyday

That's it
