Debugging missing values in Handlebars.js

If some of your data fields are displaying correctly while others are not, it suggests that the issue might be related to how those fields are populated in your dataset or how they are being accessed in your Handlebars template.

Here are a few steps you can take to troubleshoot and resolve the issue:

1. Check Data Population: Ensure that all the fields (release_date and type) are being correctly populated in your dataset before being passed to the Handlebars template. You can log the data object before passing it to the template to verify the presence of these fields.

2. Verify Data Existence: Double-check that all the records in your dataset actually have values for the release_date and type fields. If any of them are missing or empty, they won’t be displayed in the template.

3. Handle Missing Data Gracefully: Modify your template to handle cases where the release_date or type fields are missing or empty. For example, you can use Handlebars’ built-in if helper to conditionally display these fields only if they exist:

{{#if release_date}}
  <p class="subtitle is-6">Release Date: {{release_date}}</p>
{{/if}}

{{#if type}}
  <p class="subtitle is-6">Type: {{type}}</p>
{{/if}}

This way, even if some records are missing these fields, your template won’t break.

4. Ensure Correct Field Names: Verify that the field names (release_date and type) are correct and match exactly with the keys in your dataset. Handlebars is case-sensitive, so any mismatch in field names will cause those fields not to display.

5. Inspect HTML Output: Inspect the HTML output of your Handlebars template in the browser’s developer tools. This can help you identify if the fields are present in the rendered HTML but not displaying correctly due to CSS styling or other factors.

Wrap-up

By following these steps, you should be able to identify and address the issue causing release_date and type fields not to display on your webpage.
