Troubleshooting FAQ Plugin Visibility in django-cms: A Comprehensive Guide

When developing websites with django-cms, one common issue developers face is the discrepancy between content available in edit mode and what is displayed on the published page. A specific case arises with FAQ plugins where, although the FAQs are visible in edit mode, they fail to appear once the page is published. In this guide, we’ll dive into this problem and discuss how to make sure your FAQs show up correctly on your live site.

Understanding the Problem

Imagine you’re setting up an FAQ plugin on your django-cms website. Everything appears to work perfectly in the edit mode—you can see and manage your FAQs without any issue. However, as soon as you switch to the published view, those FAQs vanish. Upon examining your queryset, you find it empty when the page is live.

Why This Happens

This issue is often related to how the FAQ plugin model is defined and how relationships between models are established. The FAQs are not retained when the data is rendered for public viewing due to potential misconfigurations in the model setup or data relationships. Let’s look at our proposed solution to rectify this.

Step-by-Step Solution

1. Update the FAQPluginModel

To ensure that the FAQ items are correctly associated with the plugin model, you should define a relationship using a ManyToManyField. This allows multiple FAQ items to be linked to the FAQ plugin model. Here’s how you should update your FAQPluginModel:

ManyToManyField: This establishes that multiple FAQItem instances can relate to a single FAQPluginModel, allowing for scalable management of FAQs.

blank=True: This attribute ensures that it's not mandatory to have FAQ items provided, catering to the flexibility of your content creation.

2. Update copy_relations Method

The copy_relations method is critical in ensuring that when an instance is copied (for instance, when creating a new plugin from an existing one), the related FAQ items are also copied correctly. In the example above, the faq_items.set(oldinstance.faq_items.all()) line effectively duplicates the related FAQ items from the old instance to the new one.

3. Review Your Plugin Rendering Logic

You may also want to ensure that your plugin’s rendering method is correctly set to fetch and display the FAQ items:

This method updates the context with the FAQ items retrieved from the associated FAQPluginModel instance. It’s crucial that you use the correct queryset to fetch these items successfully.

Conclusion

By following these steps, you should be able to resolve the issue of FAQs not displaying on your published pages in django-cms. Properly defining relationships within your models is essential to ensure that content translates seamlessly from edit mode to live pages. If you run into any further concerns, communities such as Stack Overflow or the official django-cms documentation can provide additional insights and support.

Implement these changes and watch your FAQ section thrive in both edit and published modes—with clear, helpful responses right at your users’ fingertips.
