Fixing Scrapy Parsing Issues: How to Retrieve Your Favorite Team's Score

Are you new to Scrapy and grappling with parsing data? If you're trying to collect your favorite team's score but finding that your JSON file remains empty, you're not alone. This issue is quite common among beginners. Let’s dive into the problem and explore a clear, structured solution to get your desired data.

Identifying the Problem

In the initial attempt with Scrapy, many users report receiving an empty JSON file after running their spider. This usually indicates that the code did not correctly fetch the necessary data from the web page. Here's a summarized version of the initial code that caused the issue:

Key Issues in the Original Code:

Incorrect data extraction logic: When examining the response, it’s possible that the CSS selectors in use weren’t targeting the right elements.

Missing custom settings: Custom feed settings may not have been properly defined in some cases, which could lead to empty output.

The Solution

Let’s walk through the corrected version of your Scrapy spider step by step. Here’s the updated code that resolves the parsing issue:

Breakdown of the Key Improvements:

Custom Settings: We now have a section that specifies the output format directly in the spider itself, ensuring the feed settings are correctly implemented.

Correctly Setting Up Main Process: The spider is executed with the correct settings using get_project_settings() which ensures it operates as intended.

Expected Output

When the corrected spider runs successfully, you will find data in your Soccerway.json file like this:
