Question 1

How to set up file uploads with Ckeditor gem in Rails?

Accepted Answer

Choose a backend like active_storage or carrierwave, then run the appropriate Rails generator (e.g., `rails generate ckeditor:install --orm=active_record --backend=active_storage`). Mount the engine in routes and precompile assets as per the README for a functional setup.

Question 2

Can I use CKEditor 5 with this gem?

Accepted Answer

No, the gem explicitly supports only CKEditor 4.x. For CKEditor 5, you'll need to integrate it manually or seek alternative gems, as CKEditor 5 has a different architecture and is not compatible with this integration.

Question 3

How do I secure the file browser in Ckeditor with Pundit?

Accepted Answer

Configure the gem to use Pundit in an initializer, then generate policies with `rails g ckeditor:pundit_policy`. Customize the generated policy files to define access rules for Ckeditor models like Picture and AttachmentFile.

Question 4

Ckeditor gem vs Rails Action Text: which is better for rich text editing?

Accepted Answer

Action Text is built into Rails 6+ and uses Trix editor with active_storage, offering simplicity and tight integration. Ckeditor gem provides more advanced editing features and backend flexibility with CKEditor 4, but requires more setup and maintenance. Choose based on your need for customization versus out-of-the-box Rails support.

Question 5

How to customize the CKEditor toolbar in a Rails app?

Accepted Answer

Create a config.js file in app/assets/javascripts/ckeditor/ and define custom toolbars using CKEDITOR.editorConfig. Override the default configuration as shown in the README, ensuring to set all options manually if you copy the base config.

Question 6

Does Ckeditor gem work with Turbolinks?

Accepted Answer

Yes, but it requires additional JavaScript setup. As per the README, you need to create a file that reinitializes CKEditor on page loads, typically using jQuery or similar to handle Turbolinks events for proper editor functionality.

Question 7

What are the performance impacts of using Ckeditor in Rails?

Accepted Answer

CKEditor adds client-side JavaScript load, which can affect page load times. The gem's backend components for file uploads may introduce database and storage overhead, so optimize with caching and asset management for larger-scale applications.
