Foundation 5's accordion works great when I use it as per the documentation and open that page directly. However, if I click to another link on my site and then click to the page with the accordion, then the accordion doesn't expand when I click on the headings :(. I figured maybe it's the turbolinks JavaScript messing with Foundation's accordion. So we added this to the link to the page with the accordion:
<li data-no-turbolink><%= link_to 'My accordion page', accordion_page_path %></li>
Now it works better, but not perfect. If I go to my accordion page from another page, the accordion works. But then when I navigate away and click the back button on my browser, stops working :(.
This must be an extremely common problem as Foundation and Rails are very popular. Any way to get this to work?
Yes, turbolinks can cause many issues with RoR.
The reason turbolinks breaks your javascript is that document.ready events won't trigger properly. You need to do it on change instead.
Option 1. Revise all of the Javascript (Not easy or recommend)
var on_load = function() {
}
$(document).ready(on_load)
$(window).bind('page:change', on_load)
Option 2. Use the Jquery-Turbolinks gem.
The jquery turbolinks gem is designed to get around this problem. However, you need to read the docs, and make sure to install it properly. (It's a tricky beast.)
Option 3. Remove Turbolinks
If it's causing you to much trouble, you can just remove it. Delete it from the gemfile, remove turbolinks-tracked: true from your assets in the application layout, and wave turbolinks goodbye. I will admit, I have done this several of times. :\

I see in my application.js file //= require turbolinks. I was wondering what turbolinks does in rails 5.0 because it is somehow getting in the way of my bootstrap buttons. Can someone please explain what turbolinks is and how i can fix my bootstrap problem?
Turbolinks is a gem that speeds up your app and makes it behave like a SPA (Single Page App), it does this by loading only the content between your body tags (using javascript) basically by making and AJAX request to the server, waiting the answer, deleting the old content and replacing it with the new content, handling the URL and browsing history.

Simple Explanation By Analagy:
Imagine you have a yellow page directory (a physical book directory). Every now and then, one or two phone numbers require updating. Rather than simply ordering an entirely new directory, you simply edit, within the directory itself, the phone numbers that need to be edited.
It's a LOT faster, and less expensive.
How do you know what numbers need to be edited? Well you'd make a phone call (AJAX request) and the yellow pages people will simply tell you that what certain few numbers need changing.
In other words, only the parts of the page which need changing will be changed with turbolinks. The problem with turbolinks is that it might not always be compatible with other javascript libraries out there.
I am developing an app using Ruby on Rails. In a specific view I have a textarea that uses Bootstrap Markdown.
The problem is that each time I visit that view, the textarea is rendered completely plain, without the Markdown functionality. Hitting F5 (refresh) renders the form correctly.
I tried to clear my browsers cache etc, but no luck. I always have to hit refresh to see the page correctly.
What may cause that?
Edit:
I am using this Markdown Plugin
I have also included the js files as stated in this question.
The turbolinks gem has been known to interfere with other javascript files and it's recommended that you remove it completely unless you really need it.
As Mohammad AbuShady said in his comment, you'll need to edit the part of the javascript files for your markdown that tells the page to start rendering. In your case this involves adding
$("#some-textarea").markdown({autofocus:false,savable:false})
inside page:load on the relevant pages.
In case you need turbolinks still, I found this very helpful: JQuery gets loaded only on page refresh in Rails 4 application
I had the same issue and adding jquery-turbolinks gem allowed the bootstrap-markdown editor to load perfectly for me.
For some reason, jQuery Mobile is returning blank pages sometimes when I use the back/forward button on my web browser.
So I searched around and a lot of people say to turn off AJAX, and your back/forward buttons will work better.
So I added the following code to my program:
$(document).bind("mobileinit", function(){
$.mobile.ajaxEnabled = false;
});
This way, each web page loads in its own URL.
So I put this in, but some pages still give me a blank page when I click on the link.
The URL hits the browser, so I know AJAX is disabled.
Pressing "Refresh" on the browser loads the page properly.
Perhaps there is a conflict with the Rails Turbolinks? That's the only idea I can muster for the cause of the problem.
I am using jQuery 1.4.5 on Ruby on Rails 4.1.7.
I figured out the solution to the problem. In rails 4, when you load jquery, you have to add the gem "jquery-turbolinks" to your Gemfile. Then load:
//= require jquery.turbolinks
in your application.js file. This line has to come AFTER "//= require jquery" and BEFORE "//= require turbolinks". After that, jquery-mobile works fine in rails 4
I can't seem to find a similar issue
On my website I am running into an issue where the browser progress bar will not show until the page is completely rendered.
This is particularly bad on a very slow page (which I am working on). It makes it look like the link may have been broken instead of just taking a little while.
Looking at the network
There is a GET method on the current page which returns a 304, this runs for about 3-5 seconds.
Once that finishes the new website will load with a near instant progress bar.
I am not sure what code I can share since this is happening everywhere on my site, it is just more noticeable on certain pages.
To see it at its worse go to http://www.swtorconquest.com/conquestweeks and click either "The Trade Emporium" or "Clash in Hyperspace".
I am having this issue both when testing locally and when the site is deployed.
I am using ruby 2.1.2 and rails 4.1.5
Do one thing, in application.html.erb, in body tag add this, it will solve your problem
<body data-no-turbolink>
The problem will almost certainly be Turbolinks, although this is just a guess. Lacking any other answers, I'll hopefully be able to give you some ideas:
When you load a page with Turbolinks, it will actually load the <body> tag of the page through Ajax, leading the <head> intact.
This causes a lot of problems if not handled correctly, one of which (we've found) being that your browser can no longer determine how quickly the page is loading. This is likely what your problem is.
Although I don't have an outright fix, I do have a test.
You can try removing any references to Turbolinks throughout the various pages in this part of your application. This can be done by using the following:
#app/views/layouts/application.html.erb
<%= javascript_include_tag "application" %> => remove the turbolinks reference
<%= stylesheet_link_tag "application" %> => remove the turbolinks reference
Also, you need to remove Turbolinks from your Gemfile & your application.js:
#app/assets/javascripts/application.js
//= require turbolinks => remove this line
This will give you the ability to gauge whether it's turbolinks which is preventing the status bar from loading correctly. If it is, then you'll have to work around this (I don't have any remedies off hand)
It must be noted that this test will not speed up the load time - it will merely show whether the status bar issue is caused by Turbolinks or not
When I click on a link and move to a new page, my form doesn't submit.
It works normally if I refresh though. It also works normally after disabling Turbolinks.
How can I resolve this and keep using Turbolinks?
jquery.turobolinks gem sorted out a similar issue i was having. Just make sure you include it directly after jquery.
It just makes all your js bindings etc still work with turbolinks
