rails-bootstrap | Rails 5.1 starter app | Application Framework library

You try to do that like, below

I think that the style is added by JS from bootstrap. On the other hand, this should work:

Answering my own question here in case someone else comes across it.

If using a helper, all options must be prefixed by date- else they won't work. That's the reason why only the date-format worked for me. I believed that property was named as such and that the prefix didn't apply to the rest of the options. So, a working version of the specified options within an helper would look like this, in my case:

I ended up rebuilding the gem file line by line starting with just rails and pg and then pasting and bundle installing each new line.

I found I was hanging on "Sinatra".

None of the errors I found in bundling the complete gem file appeared in the line-by-line bundle. Sigh.

I believe the problem could be the grails version you have 'grails-2.5.6'.

The jB CE 4.x version is based on grails-2.4.3. You should use that.

I found out that I was loading my custom javascript twice which was causing the navigation to toggle twice (so nothing was changing when pressing the hamburger menu). Important lesson behind this: search in your console to see which JavaScript files are dealing with classes that you are having issues with (in my case the toggled class) and see if you have repeated yourself. It will cause problems.

In case if anyone needs help on this - With grails 2.4.4, the groovyPagesTemplateEngine is moved to a different jar by name grails-web-gsp-2.4.4.jar

Including this along with grails-web-gsp-taglib-2.4.4.jar resolved the issue.

Thanks to Gerry's comments I found the solution to my problem, it is in the CSS so I did change the code to:

this is my advise.

I add the following resources that may help in finding a solution.

I read all the guides that can be found by searching rails asset pipeline, but I will not link them all

My advice is to check the fingerprint of the application.css and application.js both with the Chrome Developer Tools (by going in any screen element, opening the developer toolbox with f12 and checking any style of any div or any js file). You will need to check which fingerprint version of the file is used, then open that version with the text editor and check what is loaded in the fingerprint version of the file.

If your file (for ex. user.js) is loaded at the bottom of the manifest, you should easily find it at the bottom of your fingerprinted application.js.

If you want to update this file you can run

rake assets:precompile

This will precompile assets only in development, for production you need to specify the environment. It will change that fingerprinted file application.css and application.js with the editing you have done.
