TDM 40200: Project 10 — 2023
Motivation: Dashboards are everywhere — many of our corporate partners' projects are to build dashboards (or dashboard variants)! Dashboards are used to interactively visualize some set of data. Dashboards can be used to display, add, remove, filter, or complete some customized operation to data. Ultimately, a dashboard is really a website focused on displaying data. Dashboards are so popular, there are entire frameworks designed around making them with less effort, faster. Two of the more popular examples of such frameworks are
shiny (in R) and
dash (in Python). While these tools are incredibly useful, it can be very beneficial to take a step back and build a dashboard (or website) from scratch (we are going to utilize many powerfuly packages and tools that make this far from "scratch", but it will still be more from scratch than those dashboard frameworks).
Context: This is the ninth in a series of projects focused around slowly building a dashboard. Students will have the opportunity to: create a backend (API) using
fastapi, connect the backend to a database using
aiosql, use the
jinja2 templating engine to create a frontend, use
htmx to add "reactivity" to the frontend, create and use forms to insert data into the database, containerize the application so it can be deployed anywhere, and deploy the application to a cloud provider. Each week the project will build on the previous week, however, each week will be self-contained. This means that you can complete the project in any order, and if you miss a week, you can still complete the following project using the provided starting point.
Scope: Python, dashboards
The following questions will use the following dataset(s):
Let’s start this project with a fresh slate: fresh frontend and backend to work on.
mv $SCRATCH/imdb $SCRATCH/imdb.bak4
cp -a /anvil/projects/tdm/etc/project09/* $SCRATCH/imdb
cp /anvil/projects/tdm/data/movies_and_tv/imdb.db $SCRATCH/imdb/backend/api/
Then, to run the API, first load up our Python environment.
module use /anvil/projects/tdm/opt/core
module load tdm
module load python/f2022-s2023
Next, find an unused port to run the API on.
find_port # 7777, for example
Then, run the API using the port from the previous step, in our case, 7777.
python3 -m uvicorn backend.api.api:app --reload --port 7777
In addition, open another terminal to run the frontend using another port, in our case, 8888.
python3 -m uvicorn frontend.endpoints:app --reload --port 8888
You can visit the following links to see the barebones pages.
This is all you need to do for this question — just make sure those pages load up correctly.
Code used to solve this problem.
Output from running the code.
The goal of this project is straightforward. Use
htmx and make the modifications needed in order to update the following page so that it behaves like this
Make the modifications needed so you can see the following. Of course, if you added your own custom CSS, that is perfectly fine, the behavior is what is critical.
These are links that you may find helpful:
To make a request and pass along the form data, you can use the following code:
This effectively transforms this part of the web app into a SPA (single page app) — you will notice that in the example, the URL does not change.
You don’t need to modify the backend at all — this project is all about the frontend.
Make sure that if you update an actor that is not yet dead, that you don’t leave "None" when updating the death date — this will throw an error since "None" is not a valid number. Just put in a number like 2050 or 2100.
You’ll ultimately just need to modify:
You’ll ultimately just need to add a single endpoint to
Code used to solve this problem: the templates you updated, and
GIF or video demonstrating the behavior of the web app — just like the example gif, but using a different actor. Be sure to include the entire screen, including the URL bar.
