When dealing with rich text user input in Rails, what is considered the best approach? While Markdown seems promising, I am struggling to find a user-friendly editor for set up and unsure about how to properly sanitize the HTML. The sanitize helper still permits certain elements like </div>, which disrupts my layout. My goal is to ensure that the sanitized code adheres to XHTML Strict standards.
My choice was TinyMCE due to its ability to clean up the HTML code by filtering out unwanted tags and attributes. You can refer to the valid_elements option in the documentation for more information.
However, it is important to note that these sanitization features may not be effective if someone inputs malicious code directly (such as through curl without using a browser). To prevent such issues, I utilize Tidy along with TidyFFI.
(Unfortunately, I cannot provide links as sharing malware-related content is prohibited)
According to this discussion, it seems that Yahoo's UI library editor is a recommended choice. Remember to always utilize the search function first! :)
