How to Read Files Without Extensions in Django: A Step-by-Step Guide

When building web applications using Django, you may encounter a situation where you need to read files from a specific directory and display their names without showing the file extension. In this guide, we will explore a common problem faced by developers: how to remove file extensions when displaying file names and handle potential errors such as FileNotFoundError.

Understanding the Problem

Let’s set the stage with a common scenario. You are working on a Django web app where:

You have implemented a function to upload CSV files to a specific directory on your computer.

You have another function to read these files and display them on your website.

However, you want to show only the file names without the .csv extension. While attempting to achieve this, you're encountering errors, such as FileNotFoundError.

The Solution

To resolve this issue, let's break down the solution into clear steps. We will focus on iterating through the directory, removing the file extensions, and displaying the file names.

Step 1: Iterate Through the Directory

First, you need to list all files in the specified directory. You can accomplish this using the os module in Python, which provides a simple way to interact with the file system.

Step 2: Remove File Extensions

Next, you'll want to process each file name to remove the .csv extension. This can be easily done by using Python’s string manipulation capabilities.

You can use the following code snippet to remove the extensions:

Step 3: Return the List in the Response Context

Finally, you will need to return the cleaned list of file names in your response context so that it can be accessed in your Django template. Here's how you can do that:

Reading and Displaying the CSV Content

While the above steps cover removing file extensions, you also need to ensure you're effectively reading the content of these CSVs. Below is a brief walkthrough:

You can use Pandas to read the CSV files, which provides a powerful tool for data manipulation. Your function can read the files and convert the data frames to HTML format:
