We're excited to see that you're interested in joining ADI Labs for the Fall 2019 semester!
In Labs, we build products that are deployed and used by hundreds of students here at Columbia and beyond. We've put together a quick technical diagnostic to familiarize yourself with Flask, HTML/CSS, Git/GitHub, and basic data structures. This portion will help us ensure that you are fully supported by your team and to get a taste of your skillset and creativity. Just try your best!
This diagnostic requires Python 3, a basic text editor (ex. Sublime/VS Code/TextEdit), Git (pre-installed on most computers), and a GitHub account. Please complete this challenge on your own.
ADI wants to help the Columbia community during finals and midterms by telling them how crowded a specific library is, or what is the best place to study. To do so, we want to create a simple and "light" website based off Density's tools.
Fork this repository. If you don't have a github account, please create one.
Create a new branch from master and name it dev on your forked repo. Clone the repo (if you haven't already).
On the dev branch, create a dynamic endpoint /information/<query>. A student queries this endpoint with a string that represents either a number or a building_name. Your task is, given a building_name, display how full that building is, and given a number, display the number-least crowded places, including how full they are. NOTE: Do NOT hardcode your API key obtained through density's website (however you solve this setback, make sure to specify it in the documentation).
For example, if I navigate to localhost:5000/information/Butler, my page will look like the following:
Take into account that the user may input building name with lowercase too, and the website should be flexible enough not to break with this small change (e.g. localhost:5000/information/butler).For the case where a building_name has whitespace (e.g. "Lehman Library"), you may assume that the url format will use underscores instead (e.g. "Lehman_Library"). You do not have to take into account input more malicious than those two cases.
Similarly, if I navigate to localhost:5000/information/8, my page will look like the following:
You will find these libraries and websites helpful in completing this task:
- Flask Installation
- Flask Quickstart Tip - check out "variable rules" section
- Requests
- Density -- specifically this page
- Buildings Info
- Density API Docs
In Labs, documentation is a vital part of our day-to-day experience. Make sure to provide good documentation for what you did!
Commit your changes and push the new branch to your forked repository. Make sure that the changes are visible on the forked branch. When you've completed these steps, copy the link of your forked repo with the changes into your application. Thanks for completing the Labs challenge!
