Fix rendering issues by flushing Rails' cache
When you use Rails caching to optimize your view layer in production you might run into rendering issues. “What, I thought I changed this HTML and it worked for me in development!” Flushing the cache might be a brutal but effective solution.
You may know the phrase. “There are only two hard things in Computer Science: cache invalidation and naming things.” by Phil Karlton. Well, if you have rendering issues on production you may just fix them by flushing the whole cache. Running
in the Rails console worked wonders.
However if it takes too long for you cache to warm up you better resort to more directed solutions :)
