I am trying to add a header to the spree commerce website using deface. But the problem is logo is not getting loaded. I have tried the following ..
I have pasted the logo.png file in app/assets/images and in the config/initilazers/spree.rb
I have added config.logo = 'logo.png' in the block existing there.
This was not working, so I added logo.png in the vendor/assets/images.(I created the images folder)
This is the code I am having
Deface::Override.new(:virtual_path => 'spree/shared/_header',
:name => 'Tryint to replace the header',
:replace => 'div#spree-header',
:text => '
<div class="container">
<nav class="navbar navbar-fixed-top navbar-default">
<div class="container">
<div class="navbar-header">
<button type="button" class="navbar-toggle" data-toggle="collapse" data-target="#myNavbar">
<span class="icon-bar"></span>
<span class="icon-bar"></span>
<span class="icon-bar"></span>
</button>
<a class="navbar-brand" href="#">
<img src="logo.png">
</a>
</div>
<div class="collapse navbar-collapse" id="myNavbar">
<ul class="nav navbar-nav">
<li class="active">Home</li>
<li>BIRTHDAY</li>
<li>ANNIVERSARY</li>
<li>WEDDING</li>
<li>CHRISTMAS</li>
<li>CORPORATES</li>
<li>STORE</li>
</ul>
</div>
</div>
</nav>
</div>
'
)
The above code file is present in the overrides/update_header.rb. It works fine except the logo does not show
I was using img tag in html, instead of using image_tag as in rails way. And it should be like this <%= image_tag("rails.png") %> where rails.png is in app/assets/images

According to this doc: http://grailsrocks.github.io/grails-platform-core/guide/nav.html
You should be able to put the following in your main layout:
<nav:primary/>
<nav:secondary/>
and it should magically add all your controllers according to the docs:
To get you started quickly, all your controllers will be
automatically registered in the "app" scope and each controller has
sub-items for each of it actions.
How to reproduce:
created an app with grails create-app
added a domain object with grails create-domain-class Address
added a few string fields to the Address class.
created a scaffolded controller thus:
class AddressController {
static scaffold = Address
}
edited the /views/layouts/main.gsp thusly:
</head>
<body>
<nav:primary/>
<nav:secondary/>
<!---
<div class="navbar navbar-default navbar-static-top" role="navigation">
<div class="container">
<div class="navbar-header">
<button type="button" class="navbar-toggle" data-toggle="collapse" data-target=".navbar-collapse">
<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="/#">
<asset:image src="grails.svg" alt="Grails Logo"/>
</a>
</div>
<div class="navbar-collapse collapse" aria-expanded="false" style="height: 0.8px;">
<ul class="nav navbar-nav navbar-right">
<g:pageProperty name="page.nav" />
</ul>
</div>
</div>
</div>
---!>
<g:layoutBody/>
<div class="footer" role="contentinfo"></div>
Ran the app. The result was just a blank navigation, and the nav tags were unaltered in the resultant page in the browser.
I also tried doing "grails generate-all Address" to create the static view and controller, and I added the following line in the controller:
static navigationScope = 'app'
But this had no effect either.
The collapsed navbar for mobile versions will not open. The website is www.insaka.org. This is the navbar code. I could have sworn it was working last time I checked it, but now it is not. Any ideas?
<div class="container">
<nav class="navbar navbar-expand-md fixed-top navbar-dark">
<a class="navbar-brand" href="/">Home</a>
<button class="navbar-toggler" type="button" data-toggle="collapse" data-target="#navbarsExampleDefault" aria-controls="navbarsExampleDefault" aria-expanded="false" aria-label="Toggle navigation">
<span class="navbar-toggler-icon"></span>
</button>
<div class="collapse navbar-collapse" id="navbarsExampleDefault">
<ul class="navbar-nav mr-auto">
<%= render 'layouts/navigation_links' %>
<% render 'layouts/nav_links_for_auth' %>
</ul>
<div>
Donate
</div>
<div>
<img class="featurette-image img-fluid mx-auto img-responsive max-width:25px height:auto" src="../images/blue insaka logo.jpg">
</div>
</div>
</nav>
If you check for javascript errors in the console you will find the problems:
popper.min.js
bootstrap.min.js
holder.min.js
These three js files could not be found.
I have strange error with images (never encountered it before).
This is screenshot of the main page - <%= render 'layouts/header %>
Nothing wrong there...
Now - I have put same code (<%= render 'layouts/header %>) into devise/sessions/new.html.erb and it does not read logos anymore.
(same happens with footer)
-> How to fix this?
-> How to prevent it in future?
I thought that rails will always load images the same way it does every time.
header.html.erb
<header id="home">
<div class="main-nav">
<div class="container">
<div class="navbar-header">
<button type="button" class="navbar-toggle" data-toggle="collapse" data-target=".navbar-collapse">
<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="index.html">
<h1><img class="img-responsive" src="assets/logo.png" alt="logo"></h1>
</a>
</div>
<div class="collapse navbar-collapse">
<ul class="nav navbar-nav navbar-right">
<li class="scroll active">Home</li>
</ul>
</div>
</div>
</div><!--/#main-nav-->
Fixed
Problem was that I should have used image_tag instead of standard html img src.
So:
This:
<img class="img-responsive" src="assets/logo.png" alt="logo">
Should be changed to this:
<%= image_tag("logo.png") %>
I am using bootstrap from a CDN with my rails app. Most of the styling works except for the carousel on the home page. It works fine in development but not at Heroku. I don't know if this is relevant but I have defined this route in routes.rb: root "home#index" which displays index.html.erb via the HomeController. The first image in the carousel is loaded but that is it. It has no functionality. Right now I have no bootstrap gems in the gem file which I will try if necessary. I just wanted to see if anyone has seen this issue before and knows what to do. I think this file is OK since it works in development but here is index.html.erb:
<div id="myCarousel" class="carousel slide img-rounded" data-ride="carousel">
<!-- Indicators -->
<ol class="carousel-indicators">
<li data-target="#myCarousel" data-slide-to="0" class="active"></li>
<li data-target="#myCarousel" data-slide-to="1"></li>
<li data-target="#myCarousel" data-slide-to="2"></li>
<li data-target="#myCarousel" data-slide-to="3"></li>
<li data-target="#myCarousel" data-slide-to="4"></li>
</ol>
<!-- Wrapper for slides -->
<div class="carousel-inner" role="listbox">
<div class="item active">
<%= image_tag("nicholson2.jpg", alt:"nicholson", class: "img-rounded") %>
</div>
<div class="item">
<%= image_tag("marilyn2.jpg", alt:"marilyn", class: "img-rounded") %>
</div>
<div class="item">
<%= image_tag("pacino2.jpg", alt:"pacino", class: "img-rounded") %>
</div>
<div class="item">
<%= image_tag("lily.jpg", alt:"lily", class: "img-rounded") %>
</div>
<div class="item">
<%= image_tag("deniro2.jpg", alt:"deniro", class: "img-rounded") %>
</div>
</div>
<!-- Left and right controls -->
<a class="left carousel-control" href="#myCarousel" role="button" data-slide="prev">
<span class="glyphicon glyphicon-chevron-left" aria-hidden="true"></span>
<span class="sr-only">Previous</span>
</a>
<a class="right carousel-control" href="#myCarousel" role="button" data-slide="next">
<span class="glyphicon glyphicon-chevron-right" aria-hidden="true"></span>
<span class="sr-only">Next</span>
</a>
</div>
I resolved this by using https: instead of http: when linking to external resources. It works in development but evidently heroku does not allow it.
I had the same issue, in my case i had to remove the //=require jquery_ujs from the application.js file (assets/javascripts/application.js). Hopefully it will resolve the issue. :)
I want to have a navbar that collapses when I resize the screen, so I thought to use Bootstrap.
In the application.html.erb:
<body>
<div class="navbar navbar-fixed-top">
<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>
<a class="brand" href="#">Some Store</a>
<div class="nav-collapse">
<ul class="nav">
<li><%= link_to "Browse Products" %></li>
<li><%= link_to "Price List" %></li>
<li><%= link_to "Contact Us" %></li>
<li><%= link_to "Cart" %></li>
</ul>
</div>
</div>
</div>
</div>
In the Gemfile I have gem 'bootstrap-sass'
In the application.css.scss I wrote #import 'bootstrap;'
In the application.js I have //= require bootstrap
I don't understand why It doesn't work, I just copied from the bootstrap site
Your imports are correct, but your current markup is not. It doesn't match the markup and classes that I see in some of the examples. I first attempted to build from your markup while using the sticky footer with fixed navbar example in the bootstrap docs as a guide to get the markup to display properly. Here's how I adjusted your markup:
<div class="navbar navbar-default navbar-fixed-top">
<div class="container">
<div class="navbar-header">
<button type="button" class="navbar-toggle" data-toggle="collapse" data-target=".navbar-collapse">
<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="#">Some Store</a>
</div> <!-- end div class="navbar-header" -->
<div class="collapse navbar-collapse">
<ul class="nav navbar-nav">
<li class="active"><%= link_to "Browse Products" %></li>
<li><%= link_to "Price List" %></li>
<li><%= link_to "Contact Us" %></li>
<li><%= link_to "Cart" %></li>
</ul>
</div> <!-- end div class="collapse navbar-collapse" -->
</div> <!-- end div class="container" -->
</div> <!-- end div class="navbar navbar-default navbar-fixed-top" -->
If you look closely, I swapped the locations of the divs with classes container and navbar-inner and changed the class to <div class="navbar-header"> that surrounds the collapse button. Then I had to change div surrounding the menu items to have class navbar-collapse instead of the nav-collapse that you had, otherwise the menu items disappear. In order for the button to work, I changed it from an <a> tag to a <button> tag as well as the data-target="navbar-collapse" attribute to correctly target the collapsible menu items. Once these changes were made, I had a functioning drop-down menu for window sizes < 768px.
And don't forget to add a style to your <body> tag for padding-top:51px; to guarantee your site content appears underneath the fixed navigation bar.
Hope that helps!
Chris
