I use Rails 5.1 and have a javascript file in app/assets/javascripts vex.combined.js and how can I require it within application.js?
//= require jquery
//= require rails-ujs
//= require_tree .
var vex = require('vex.combined');
returns an error in browser console: ReferenceError: require is not defined
Update:
By using //= require vex.combined
How can I transform vex.registerPlugin(require('vex-dialog')); ?
It returns
ReferenceError: require is not defined
too.
Look, you don't need to use this var vex = require('vex.combined');
Rails Asset Pipeline:
The asset pipeline provides a framework to concatenate and minify or compress JavaScript and CSS assets. It also adds the ability to write these assets in other languages such as CoffeeScript, Sass, and ERB.
For example
When we include a file using application.js like //= require select2 then we access to this all methods like after requiring this then we just called the method like select2();
$("#ID").select2();
when we remove this //= require select2 from application.js then it will show
ReferenceError: select2 is not a function
Try the following.
For the most common usage of vex, you'll want to include vex, vex-dialog, the vex CSS file, and a theme file.
//= require vex.combined
make sure directory is ok, then try to run basic alert like
vex.dialog.alert('Thanks for checking out vex!')
that's actually ok.
var vex = require('vex-js')
vex.registerPlugin(require('vex-dialog'))
Above two lines code for browserify/webpack setup which you are trying.

I'm trying to use Bootstrap Combobox for rails.
The instructions say that:
*"You will need two files included in your HTML in order for this to
work:
js/bootstrap-combobox.js
css/bootstrap-combobox.css*
I realise that they need to go in the application js and application css respectively, but I think that I'm getting the syntax wrong because I'm getting an error.
This is how I'm adding to application.css.scss:
* require css/bootstrap-combobox.css
This is how I'm adding to application.js:
//= require bootstrap-combobox
What error are you getting?
Without knowing the exact error, here's what I suggest:
After you make sure you have a file in your assets/stylesheets named bootstrap-combobox.css, you want your require statement to look like this:
*= require bootstrap-combobox
Your require statement looks fine for the JS assuming you have the file in the assets/javascripts folder.
You can also use //= require_tree . and *= require_tree . to require all files in your javascripts and/or stylesheets folders respectively instead as well.
Check out this section of the Rails asset pipeline for more info.
I would like to include the following datetime picker in my rails application.
http://www.malot.fr/bootstrap-datetimepicker/
I am using twitter bootstrap for rails, but can't get it to work.
I tried adding the .js file to the assets/javascripts directory and using //= require to include it in the application.js file.
The files are loading on the page, but I'm getting a response that
Uncaught TypeError: Object [object Object] has no method 'datetimepicker'
Any ideas? I've reverted all of my changes, so can start again from scratch.
application.js
//= require jquery
//= require jquery_ujs
//= require twitter/bootstrap
//= require bootstrap
//= require_tree .
I think the problem happened at //=require_tree. Yes you added that plugin but the plugin is loaded after your custom js which have method to call the plugin. That's why "Object has no method 'datetimepicker'".
I would suggest you to:
Move the plugin into vendor/assets/javascripts/. This is a better place for third party libs.
require the plugin explicitly in application, after bootstrap(it depends on bootstrap's dropdown. Like
//= require bootstrap
//= require datetime_picker_js_file_name
//= require_tree .
Side notes:
I don't quite know why there are two bootstrap js files required. Are they duplicate?
Besides, I would recommend to require Bootstrap js files only on need, like
//= require bootstrap-dropdown
//= require bootstrap-alert
I'm using RoR and jquery.ui.addresspicker.js
This jquery.ui.addresspicker.js requires that google is loaded before that library is loaded. I only need the addresspicker on a couple of pages in the application.
The google part that needs to be loaded before is this:
<script src="http://maps.google.com/maps/api/js?sensor=false"></script>
But this makes the page load slower so I don't want this on all my pages.
The application.js contains this:
//= require jquery
//= require jquery_ujs
//= require jquery.ui.all
//= require jquery.blockUI
//= require select2
//= require cocoon
//= require_tree .
Currently the jquery.ui.addresspicker.js file is in app/assets/javascripts and thus also loaded automatically all the time.
How can I handle this? Should I move the addresspicker.js out of the javascripts directory? Should I rewrite my application.js? Other suggestions?
You can replace
//= require_tree .
with an explicit list of the javascripts that you want included on each page. and just include jquery.ui.addresspicker on the pages that you need it.
I used Ian's idea to change the application.js
I created a new folder named sitewide and copied all the javascripts in there that I want to use on the whole site (so not the addresspicker).
I changed application.js like this:
//= require_tree ./sitewide
And in the page where I needed the addresspicker I put it using javascript_include_tag
This way I don't need to change the application.js file everytime I want to add a js file.
use a different layout on both pages or just remove the jquery.ui.addresspicker.js from the default_layout and just include in the pages where you need it
<%= include_javascripts "jquery.ui.addresspicker" %> or
javascript_include_tag "jquery.ui.addresspicker"
in the page where you need
I have a Rails application, and I'm using Ember on the front-end. I'd like to move the ember-related files down one level in the directory structure, but when I do, the templates no longer render.
In the plain, vanilla, working version of the application, my directory structure is:
./app/
assets/
javascripts
application.js
ember-app.js
routes.js
store.js
models/
controllers/
routes/
templates/
views/
with: application.js
//= require jquery
//= require jquery_ujs
//= require handlebars
//= require ember
//= require ember-data
//= require_self
//= require ember-app
App = Ember.Application.create();
and: ember-app.js
//= require ./store
//= require_tree ./models
//= require_tree ./controllers
//= require_tree ./views
//= require_tree ./helpers
//= require_tree ./templates
//= require ./router
//= require_tree ./routes
Everything works fine. However, I would like to move the ember-app file and all ember javascript code down one level, and when I do so, the templates do not render. (Part of the application uses Ember, but not the entire application, and I'm trying to set up two separate paths through the asset pipeline.)
The desired structure is:
./app/
assets/
javascripts
application.js
embro/
ember-app.js
routes.js
store.js
models/
controllers/
routes/
templates/
views/
with: application.js (revised: 'require ember-app' becomes 'require embro/ember-app')
//= require jquery
//= require jquery_ujs
//= require handlebars
//= require ember
//= require ember-data
//= require_self
//= require embro/ember-app
App = Ember.Application.create();
(ember-app.js is unrevised.)
As I said, after the move, none of the template content appears onscreen. No errors onscreen or in the console, just an empty ember-application.
When I examine Ember.TEMPLATES in the console, all the expected templates are listed. Furthermore, if I put the desired content in x-handlebars templates in the appropriate rails view, the content successfully renders, just as it did with the original directory structure.
For example, in apps/views/welcome/index.html....
<script type="text/x-handlebars" data-template-name="application">
<h1>hello</h1>
{{ outlet }}
</script>
<script type="text/x-handlebars" data-template-name="index">
<h1>this is the index</h1>
</script>
... and we're good to go again.
but if I leave the rails view empty, as I did with the original structure, it's a no go.
Wondering if perhaps the ember-rails gem requires the handlebars templates to be present in app/assets/javascripts/templates, and if there's a way to override this. The documentation mentions adding a templates_root option to the application configuration block, and I'm wondering if this is the key. I've played around a bit, no luck yet.
Any ideas?
UPDATE:
Afraid I'm not having any luck with the templates_root option. As an experiment, I tried building a new, simple rails app, and using the ember-rails bootstrap generator to get it up and running. All's well, but if I then attempt to simply change the name of the templates folder (i.e. app/assets/javascripts/templates -> app/assets/javascripts/temple), with appropriate changes to the sprockets includes and config files, I'm getting the same results.
Any chance the templates_root option is somehow broken?
I'm using Ruby 1.9.3, Rails 3.2.11, ember-rails 0.10.0
Any pointers to where I should look in the ember / ember-rails / handlebars source code? Have started poking around.
thanks!
You're right that you need to set templates_root. Try adding
config.handlebars.templates_root = 'embro/templates'
to the configuration block in application.rb, or
RailsApp::Application.config.handlebars.templates_root = 'embro/templates/'
to a new initializer, where RailsApp is whatever your application is named.
Edit:
I was able to reproduce the behaviour that you described with templates_root. The fix for me was to delete the /tmp folder of my application and restart rails. After that, the templates were named correctly.
Edit:
More precisely, you need to clear the sprockets cache at /tmp/cache/assets after changing templates_root.
Edit:
As mentioned in the comments below, a simple rake tmp:cache:clear should take care of the problem.
For site wide specific JS code (i.e. for the header, which appears on all pages). Where should this be placed? In:
app/assets/javascripts/application.js
Is that right?
For pages#home. Which root_url also points to (root :to => 'pages#home'). Where should my JS file be placed in the pipeline?
app/assets/javascripts/pages/home.js
And regards to my application.js. Is this right? It currently looks like:
//= require jquery
//= require jquery_ujs
//= require_directory .
Or should I just embed page specific JS in the view?
It's not a good idea to put js code in application.js. You can put that code in any other file on the assets/javascripts folder and it will be included automatically by the require_directory or require_tree command. Your application.js file is perfectly fine as it is right now, but you might want to use require_tree instead of require_directory for recursive inclusion.
For example, the javascripts files in app/assets/javascripts/pages will be included by require_tree but not by require_directory.
