Quick query… I’ve used the excellent “Getting Started with Rails” tutorial to build the demo app, Weblog. Has turned out to be a useful tool on our small Lan. I am using it daily to capture stuff I want to reference across many devices/tablets, etc. (Windows, Linux, Android, iOS-iPad, etc…)
In production mode, the Destroy/delete and image display did not work until I modified the “production.rb” file to allow live compile of assets. This meant toggle parameter setting “config.assets.compile = false” to be “config.assets.compile = true”. Then, the website (which is built and deployed on a CentOS 6.6 Linux box) would work correctly, as expected.
But hey, why not precompile my small assets? I read the incomprehensible doc on the rails “Asset Pipeline”, and found nothing that would actually tell me how the precompile my image assets and my little bit of .js stuff. (jquery.js and jquery_ujs are needed for Destroy/delete to actually work).
But in reviewing the postings here, I found this: “rake assets:precompile”. Ah. I ran this, and got what looked like good results. It returned the asset file names, with their MD5 hash strings, and indicated they are slotted into …/Weblog/public/assets/imagefilename-(big long hex hash).jpg Well, great! Just what I needed (or so I thought in my sad and foolish ignorance…)
When I run the website, of course I get crap. I get the filenames, with the big hex hash string, shown on the webpage, instead of the actual image! Arrrgh! Of course there is some secret hipster bit of trickery, that I need to deploy, to have a return to sanity and correct operation of my little website. Peradventure, someone might enlighten me as to WTF this actually is?
When I ran “rake asset:precompile”, I did get a response indicating everything was successfully precompiled. But the FAIL behaviour of my website has returned - ie. filenames are shown instead of images, and the “Destroy” option (delete method) no longer works at all. I am assuming no javascript is being sent to browser, and hence, no joy in Mudville…
As mentioned, I’ve been thru the “Asset Pipeline” Rails Guide, but document appears written for highly experienced, existing Rails developers, who need to learn about version changes - ie. from rails 2 and 3 to rails 4. It does not even mention “rake asset:precompile” anywhere.
Bottom line: What else,. after “rake assets:precompile” do I have to do, so that the “rails server … -e production” process runs correctly using the precompiled assets, and serves up the gosh darned javascript to the browser??
If someone wants to enlighten me, great. Otherwise, I will plow thru this dreck, until I determine the solution, and will post a response here. Editorial Note from GEMESYS Ltd: Guys: This should not be this difficult to make a baseline trivial app website actually work as expected, in some sort of sane production mode. N’est pas?
