undefined method `pageless' using jquery.pageless in Ruby on Rails - javascript

I'm trying to implement an infinite scroll and using jquery.pageless
But I'm getting this error: undefined method 'pageless'
I include jquery.pageless.js on my application.html.erb in assets:
<%= javascript_include_tag 'jquery-1.3.2.min', 'jquery.pageless' -%>
Any suggestion about how to solve this?

I don't know why you are using the format:
<%= javascript_include_tag 'jquery-1.3.2.min', 'jquery.pageless' -%>
in application.rb.
In assets/javascript/application.js, add those files:
// This is a manifest file that'll be compiled into application.js, which will include all the files
// listed below.
//
// Any JavaScript/Coffee file within this directory, lib/assets/javascripts, vendor/assets/javascripts,
// or vendor/assets/javascripts of plugins, if any, can be referenced here using a relative path.
//
// It's not advisable to add code directly here, but if you do, it'll appear at the bottom of the
// compiled file.
//
// WARNING: THE FIRST BLANK LINE MARKS THE END OF WHAT'S TO BE PROCESSED, ANY BLANK LINE SHOULD
// GO AFTER THE REQUIRES BELOW.
//
//= require jquery
//= require jqeury.pageless
//= require jquery_ujs
//= require_tree .
You need to make sure you have jquery installed:
gem install jquery-rails
then:
bundle install
Also make sure you have the jquery-pageless.js files in on of the paths mentioned in the application.js file so it gets picked up by the asset pipeline.

Application.js file:
// This is a manifest file that'll be compiled into application.js, which will include all the files
// listed below.
//
// Any JavaScript/Coffee file within this directory, lib/assets/javascripts, vendor/assets/javascripts,
// or vendor/assets/javascripts of plugins, if any, can be referenced here using a relative path.
//
// It's not advisable to add code directly here, but if you do, it'll appear at the bottom of the
// compiled file.
//

// about supported directives.

Ruby on Rails Submit button only works on refreshing

Basically I have a show page for b_page and I have rendered a new partial inside (for page_posts) and the submit button for it only works if it the page is refreshed or if the link is directly opened from the browser. I've checked and there are no missing divs or unopened tags etc, hence it's not an HTML issue.
Maybe it's a Turbolinks issue cause this happens in almost all of the app and if so here's my application.js.erb:
// This is a manifest file that'll be compiled into application.js, which will include all the files
// listed below.
//
// Any JavaScript/Coffee file within this directory, lib/assets/javascripts, vendor/assets/javascripts,
// or any plugin's vendor/assets/javascripts directory can be referenced here using a relative path.
//
// It's not advisable to add code directly here but if you do, it'll appear at the bottom of the
// compiled file.
//
// Read Sprockets README (https://github.com/rails/sprockets#sprockets-directives) for details
// about supported directives.
//
//= require jquery
//= require jquery.ui.all
//= require jquery.turbolinks
//= require jquery_ujs
//= require bootstrap
//= require bootstrap-tagsinput
//= require sync
//= require masonry/jquery.masonry
//= require jscolor
//= require_tree .
//= require owl.carousel
//= require turbolinks
How can I fix this? Here's the link to show.html.erb.
You must be using $(document).on('ready', function(){})
Change it to $(document).on('turbolinks:load', function (){}), this forces JavaScript to load at the time page is viewed.

Bootstrap-sass gem Javascript not Working in Rails 4

when using the bootstrap-sass gem i have loaded my css files properly, however have been receiving an error when i try loading the javascript files. I have followed the procedure of loading javascript from https://github.com/twbs/bootstrap-sass however when I view my webpage on localhost I receive the error "couldn't find file 'bootstrap'"
This is what my application.js file looks like - Any help would be much appreciated!

From the Rails 4 the :assets group isn't used anymore, please remove the group from Gemfile:
Rails 4.0 removed the assets group from Gemfile. You'd need to remove that line from your Gemfile when upgrading. You should also update your application file (in config/application.rb):
Bundler.require(:default, Rails.env)
I got it to work by removing gem 'bootstrap-sass', '~> 3.0.3.0' out of the assets group in gemfile! YAY
Did you bundle install and make sure you are loading application.js (from the assets pipeline).

Rails 3.2.13 Javascript Asset Pipeline

I am working on a Rails 3.2.13 app, and encountering the following problem:
The Javascript files I wrote in the app/assets/javascripts/ directory don't seem to be run.
I have JS code in a file called menu_list.js in the app/assets/javascripts/ directory, but it does not do anything. Whereas when I put the same code on the view page in a tag, it works.
<script>$("#sortable").sortable();</script>
Here's my application.js file:
//= require jquery
//= require jquery_ujs
//= require jquery.purr
//= require jquery-ui
//= require best_in_place
//= require bootstrap
//= require bootstrap-switch
//= require_tree .
my menu_list.js file:
$(function() {
$("#sortable").sortable();
});
It does not make sense to me, as I thought //= require_tree . would include all the javascript files in the directory. I tried other javascript files too, but they don't seem to have any effects.
$("#sortable").sortable();
If this truly is all you have in app/assets/javascripts/menu_list.js it will run as soon as the script is loaded, which is not what you want. You want to run the above code at least after the DOM has fully loaded into the page and not before.
$(function() {
$("#sortable").sortable();
});
If the environment you're running in is :development, and you properly have the following in your layout
<%= javascript_include_tag "application" %>
you will see a separate <script> tag for every Javascript file Sprockets is loading. The //= require_tree . will pick up your app/assets/javascripts/menu_list.js file.
I suggest also making sure you don't have any precompiled version of your assets in place by running the following in shell
rake assets:clean
You can also force debug mode (individual <script> tags for each file) by adding a :debug option to the above include tag
<%= javascript_include_tag "application", debug: true %>
Most common cause for this is that the call to javascript_include_tag that is on the default layout, then you create another layout, forget to add the include there and then nothing works in controllers where you use this new layout.

Why isn't DataTables working in my rails partial?

I have a table in a partial in my rails app, and I want to use DataTables to make it look nice. I am using the jquery-datatables-rails gem.
My partial:
<script type="text/javascript">
$(document).ready(function() {
$('#businesses').dataTable();
} );
</script>
<table id="businesses">
<thead>
<tr>
Bunch of headers here...
</tr>
</thead>
<tbody>
<tr>
Lots and lots of code here...
</tr>
</tbody>
</table>

The DataTables files are referenced properly in application.js and in application.css as well.
Thanks!
You should move your js code to inside your application.js file.
So, no script tags inside your html.erb, to do the javascript part you should have an application.js like that:
// This is a manifest file that'll be compiled into application.js, which will include all the files
// listed below.
//
// Any JavaScript/Coffee file within this directory, lib/assets/javascripts, vendor/assets/javascripts,

//
//= require jquery
//= require jquery_ujs
//= require dataTables/jquery.dataTables
//= require_tree .
$('#businesses').dataTable();
} );
