Bootstrap navbar dropdown randomly stops working, starts working on refresh - ruby-on-rails

I have a bootstrap navbar (version 3.3.7 - code shown below) on all pages of my ROR webapp. It has two dropdowns that work great most of the time, but quite often (about 10-15% of the time) they will just randomly stop working.
Sometimes all it takes is a quick page refresh to set things straight, and other times it takes hopping around to multiple different pages (or refreshing multiple times) to make it work again - there seems to be no definitive pattern. While refreshing the page a few times isn't the end of the world, it's obviously not ideal for end users. Any tips?

got an issues with my dropdown menu on rails

I have some issues with my dropdown menu over on rails. I'm pretty sure my code is ok, I think the main issue is with jquery and bootstrap but then again I may be wrong. I just don't know where I am mistaken. Thanks in advance!

This would be my application.js
require('jquery')
//= require popper
//= require bootstrap-sprockets
require("#rails/ujs").start()
require("turbolinks").start()
require("#rails/activestorage").start()
require("channels")
Try to add this into webpack/environment.js
environment.plugins.prepend('Provide',
new webpack.ProvidePlugin({
$: 'jquery/src/jquery',
jQuery: 'jquery/src/jquery'
})
)
environment.config.set('resolve.alias', {jquery: 'jquery/src/jquery'});
Then restart server
Hope it work !!!

Rspec undefined method `children' for nil:NilClass

I have an respec test. I have a Sizes controller and just trying to create a new size.
When i run the test i get this error and theres not much info on google about it.
It seems simple but i'm really stuck. Can anyone help please?
1) adding size allow a user to add a size
Failure/Error: visit sizes_path
ActionView::Template::Error:

My test is as follows
require "rails_helper"
RSpec.feature "adding size" do
scenario "allow a user to add a size" do
size = create(:size)
visit sizes_path
expect(page).to have_content("XXLarge")
end
end
Here is Factory Girl
FactoryGirl.define do
factory :size do
title "XXlarge"
end
end
Here is my Sizes controller
class SizesController < ApplicationController
def new
#size = Size.new
end
def create
#size = Size.new(size_params)
if #size.save
redirect_to root_url
else
render 'new'
end
end
def index
#sizes = Size.all
end
private
def size_params
params.require(:size).permit(:title)
end
end
Here is New View

The solution is embarrassing. Ive been coding for 13 hours. I was redirecting to redirect_to root_url it should be to sizes_path
def create
#size = Size.new(size_params)
if #size.save
redirect_to sizes_path
else
render 'new'
end
end

rails 4 bootstrap 3 collapsable navbar

Sorry for the newbie question, but can anyone see what I'm doing wrong? I followed the directions on the bootstrap website, and am unable to create a collapsing navbar in my web app. The list items under the ="nav pull-right" won't collapse when I decrease the width of the window. I think this maybe because I don't have a collapse plugin in my bootstrap.js. Could that be the issue?
<%= link_to "Catalyst", users_path, class: "brand" %>
<header class="navbar navbar-fixed-top navbar-inverse">
<div class="navbar-inner">
<div class="container">
<a class="btn btn-navbar" data-toggle="collapse" data-target=".nav-collapse">
<span class="icon-bar"></span>
<span class="icon-bar"></span>
<span class="icon-bar"></span>
</a>
<%= link_to "Webapp", users_path, class: "brand" %>
<div class="nav-collapse collapse">
<ul class="nav pull-right">
<li><%= link_to current_user.full_name, current_user %></li>
<li id="fat-menu" class="dropdown">
<a href="#" class="dropdown-toggle" data-toggle="dropdown">
Mailbox
<% if unread_count > 0 %>
(<%= unread_count %>)

Twitter Bootstrap navbar right allign link

Helo,
New to bootstrap and trying to use it with rails. I am trying to create a navbar and trying to display a link to the extreme right of the navbar which is not working. Here is my code:
<div class="navbar navbar-fixed-top">
<div class="navbar-inner">
<div class="container">
<ul class="nav">
<li class="active">
<%= link_to "Rubyblog", root_path, :class => 'brand' %>
</li>
<li>
Edit Account
</li>
<li>
Categories
</li>
<ul class = "nav pull-right">
Current User
</ul>
</ul>
</div>
I am trying to display the last link "Current User" to the extreme right of the navbar. Using div class"nav pull-right" doesn't seem to work: http://i.imgur.com/BEBcaIc.png
Please let me know what I am missing/doing wrong. Appreciate your inputs.
Thanks!
Mike
EDIT: Answering my question:
Pulled the "nav pull-right" out of the main "nav" class tag and it worked. Updated code:
<div class="navbar navbar-fixed-top">
<div class="navbar-inner">
<div class="container">
<ul class="nav">
<li class="active">
<%= link_to "Rubyblog", root_path, :class => 'brand' %>
</li>
<% if user_signed_in? %>
<li>
<%= link_to 'Edit Account', edit_user_registration_path %>
</li>
<li>
<%= link_to 'Categories', categories_path %>
</li>
<% if current_user.has_role? :admin %>
<li>
<%= link_to 'Users', users_path %>
</li>
<%end%>
<%else%>
<li>
<%= link_to 'Sign up', new_user_registration_path %>
</li>
<% end %>
</ul>
<ul class = "nav pull-right">
<li><%= link_to 'Welcome, '+current_user.name, edit_user_registration_path %></li>
</ul>
EDIT: Answering my question:
Pulled the "nav pull-right" out of the main "nav" class tag and it worked. Updated code in the EDIT section of my question
Have you tried making your current user like the following:
<li class="pull-right">
Current User
</li>
I'm pretty sure the reason it's losing it's styling is because you are nesting nav inside a nav.
I think you want to divide the navbar into navbar-left and navbar-right:
<nav class="navbar navbar-fixed-top" role="navigation">
<!-- Brand and toggle get grouped for better mobile display -->
<div class="navbar-header">
<button type="button" class="navbar-toggle" data-toggle="collapse" data-target="#bs-example-navbar-collapse-1">
<span class="sr-only">Toggle navigation</span>
<span class="icon-bar"></span>
<span class="icon-bar"></span>
<span class="icon-bar"></span>
</button>
<a class="navbar-brand" href="#">Brand</a>
</div>
<div class="collapse navbar-collapse" id="bs-example-navbar-collapse-1">
<div class="navbar-inner">
<ul class="nav navbar-nav">
<li class="active">
<%= link_to "Rubyblog", root_path, :class => 'brand' %>
</li>
<li>
Edit Account
</li>
<li>
Categories
</li>
</ul>
<ul class = "nav navbar-nav navbar-right">
Current User
</ul>
</div>
</div>
</nav>
The bootstrap docs talk about this and say they're a bit different than pull-right - this might explain why you're seeing issues. I haven't tested the above, but it's likely a good start.
