I have a view that should not be using a layout.
This is the controller action used :
def last
#video = Video.last
render layout: false
end
When I call the "show" view directly, it works, no layout are used.
Nonetheless, when I call that view by following a link then it actually loads the default layout with my view.
the link is present in a layout :
<%= link_to "last video", last_video_path %>
and the view :
<body marginwidth="0" marginheight="0">
<iframe type="text/html" width="100%" height="100%" frameborder="0"
src="http://www.youtube.com/embed/<%= #video %>" >
</iframe>
</body>
Any idea what I might be doing wrong ??
I finally found what was not working. In my layout, I have in the header :
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="utf-8">
<meta http-equiv="X-UA-Compatible" content="IE=Edge,chrome=1">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title><%= content_for?(:title) ? yield(:title) : "NBATopOfTheNight" %></title>
<%= csrf_meta_tags %>
<%= stylesheet_link_tag "application", :media => "all" %>
<%= javascript_include_tag "application" %>
</head>
<body>
...
the line <%= javascript_include_tag "application" %> is added by twitter bootstrap and is responsible for rendering my views even when I specify no rendering.
Deleting this line make my project works :-)

I want this nav bar work for all pages, my Requirement is make one nav

I create a nav bar inside my fragments folder that situated inside
template folder
When i call my nav bar in my index page it is not working
Here is my code of index page

I use IntelliJ IDEA as code editor.
It is possible, look into Thymeleaf Layout Dialect.
In short:
you create some layout.html in your templates folder. In it:
<!DOCTYPE html>
<html xmlns:layout="http://www.ultraq.net.nz/thymeleaf/layout">
<head>
<!-- all common head tags - meta etc. -->
<title layout:title-pattern="$CONTENT_TITLE - $LAYOUT_TITLE">App name</title><!-- define title in your page template and it will be added too your app name, e.g. 'Home - My App' -->
</head>
<body>
<nav>
<!-- your nav here -->
</nav>
<section layout:fragment="content">
<!-- don't put anything here, it will be replaced by the page contents -->
</section>
</body>
</html>
And in you page templates:
<!DOCTYPE html>
<html xmlns:layout="http://www.ultraq.net.nz/thymeleaf/layout"
layout:decorate="~{/path/to/layout.html}">
<head>
<title>Page name</title>
</head>
<body>
<section layout:fragment="content">
<p>This will be added into your layout!</p>
</section>
</body>
</html>
In order to make it work, you will need to add it to your templateEngine() bean definition:
#Bean
public SpringTemplateEngine templateEngine() {
SpringTemplateEngine templateEngine = new SpringTemplateEngine();
templateEngine.setTemplateResolver( thymeleafTemplateResolver() );
templateEngine.addDialect( new LayoutDialect() );
return templateEngine;
}
See mvnrepository to import this dialect using maven.
index.html:
<!DOCTYPE html>
<html lang="">
<head>
<meta charset="utf-8" />
<meta http-equiv="X-UA-Compatible" content="IE=edge" />

App.vue:
<template>
<div class="flex flex-col md:flex-row">

<router-view class="bg-yellow-400" />
</div>

640px Tailwind's small breakpoint (sm)
768px Tailwind's medium breakpoint (md)
Until 768px I use flex-col, and for bigger screen sizes I use flex-row as you can see in my code as well.
RESULT: (0-768px width, flex-col):
Between 640px and 768px the width of both my Nav and router-view containers stop expanding and I can see the red background of my where I mount my App.
RESULT: (>768px width, flex-row):
After 2050px, my container stops expanding which leads to the same result as mentioned before.
What can i do to workaround this behaviour?
Max width was by default 1536px. Setting max-w-full to my router-view container fixed the problem.
I am trying to use Chartist in a Node app using ejs to render my HTML . I am using the Chartist CDN and have included the necessary scripts etc in my header.ejs and set up my data model in the main.ejs file I want to render. However I keep getting "Chartist not defined error". I have tried moving the script tag into my footer, as per another answer on SO, but that didn't work either. My header.ejs and main.ejs are as follows. Is there something I am missing?
header.ejs:
<!DOCTYPE html>
<head>
<meta charset="utf-8">
<meta http-equiv="X-UA-Compatible" content="IE=edge">
<title></title>
<meta name="description" content="">
<meta name="viewport" content="width=device-width, initial-scale=1">
<link rel="stylesheet" href="stylesheets/styles.css">
<link rel="stylesheet" href="https://cdn.jsdelivr.net/chartist.js/latest/chartist.min.css">
<script src="https://cdn.jsdelivr.net/chartist.js/latest/chartist.min.js"></script>
</head>
<body>
And main.ejs
<%- include('partials/header') %>
<h1>GRAPH</h1>
<div class="ct-chart ct-perfect-fourth"></div>
<% let data = {
labels: ['Mon', 'Tue', 'Wed', 'Thu', 'Fri'],
series: [
[5, 2, 4, 2, 0]
]
};
%>
<% new Chartist.Line('.ct-chart', data); %>
<%- include('partials/footer') %>
I'm following this tutorial: http://www.thymeleaf.org/doc/layouts.html (got to Thymeleaf Layout Dialect section).
In there you can find an example:
<!DOCTYPE html>
<html>
<head>
<!--/* Each token will be replaced by their respective titles in the resulting page. */-->
<title layout:title-pattern="$DECORATOR_TITLE - $CONTENT_TITLE">Task List</title>
...
</head>
<body>
<!--/* Standard layout can be mixed with Layout Dialect */-->
<div th:replace="fragments/header :: header">
...
</div>
<div class="container">
<div layout:fragment="content">
...
</div>
<div th:replace="fragments/footer :: footer">© 2014 The Static Templates</div>
</div>
</body>
</html>
Footer and header are replaced by th:replace tag in above example, while <head> has <title> tag in layout file.
Basically, I want to replace whole <head> tag with th:replace.
Therefore, I have:
My layout file:
<!DOCTYPE html>
<html>
<head th:replace="/html/components/head :: head">
</head>
<body>
<div layout:fragment="content">
</div>
...
<div th:replace="/html/components/footer :: footer" />
</body>
<html>
My content file:
<!DOCTYPE html>
<html layout:decorator="/html/layouts/layout">
<head>
<title>My content title</title>
</head>
<body>
<div layout:fragment="content">
...
</div>
</body>
</html>
And finally my /html/components/head.htm file:
<!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml"
xmlns:layout="http://www.ultraq.net.nz/thymeleaf/layout">
<head th:fragment="head">
<meta charset="utf-8" />
<title layout:title-pattern="$CONTENT_TITLE">Layout Title should be replaced by Content Title!</title>
...
</head>
<body>
</body>
</html>
Content is alright. Footer and head are included (replaced) from files as expected but page title is blank!
I get:
<!DOCTYPE html>
<head>
<meta charset="utf-8" />
<title></title>
...
What's wrong?
Finally, I've found a way to achieve what I wanted.
In layout file <title> tag must stay. All other tags I grouped with <object> tag and annotated it as follows:
<head>
<title layout:title-pattern="$CONTENT_TITLE">Layout Title will be replaced by Page Title!</title>
<object th:include="/html/components/head :: head" th:remove="tag" />
</head>
In my html/components/head.htm file I had to remove <title> tag so it won't be duplicated after include.
<head th:fragment="head">
<meta charset="utf-8" />
<!-- NO TITLE TAG HERE -->
...
</head>
This way head fragment is included in <object> tag and thanks to th:remove="tag" <object> tag gets removed and my final HTML output is:
<head>
<title>My content title</title>
<meta charset="utf-8" />
<!-- NO TITLE TAG HERE -->
...
</head>
Obviously, I removed NO TITLE TAG HERE message too, once I got it working.
I think I found a slightly less verbose way to for using th:replace and th:fragment together, e.g. to include common <head> metadata and static resource includes in your pages.
Put the th:remove="tag" in the fragment definition, so you don't have to repeat the th:remove="tag" everytime including it.
fragment_head.html
<thymeleaf xmlns="http://www.w3.org/1999/xhtml" xmlns:th="http://www.thymeleaf.org"
th:fragment="head" th:remove="tag">
<meta charset="utf-8" />
<meta http-equiv="X-UA-Compatible" content="IE=edge,chrome=1" />
<meta name="viewport" content="width=device-width, initial-scale=1" />
<link rel="stylesheet" th:href="#{/css/vendor/bootstrap.min.css}"/>
</thymeleaf>
mypage.html
<head>
<thymeleaf th:replace="fragment_head :: head" />
</head>
You can replace whole head tag.
<!DOCTYPE html>
<html xmlns:th="http://www.thymeleaf.org">
<head lang="pl" th:replace="fragments/head :: head">
</head>
<body>
...
</body>
</html>
resources/templates/fragments/head.html:
<head lang="pl">
<title>Title</title>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8"/>
<link href="http://cdn.jsdelivr.net/webjars/bootstrap/3.3.5/css/bootstrap.min.css"
th:href="#{/webjars/bootstrap/3.3.5/css/bootstrap.min.css}"
rel="stylesheet" media="screen" />
<script src="http://cdn.jsdelivr.net/webjars/jquery/2.1.4/jquery.min.js"
th:src="#{/webjars/jquery/2.1.4/jquery.min.js}"></script>
<link href="../static/css/mycss.css"
th:href="#{css/mycss.css}" rel="stylesheet" media="screen"/>
</head>
Can anyone tell me how it is possibile that the following layout in a Rails 4 app
# app/views/layout/login.html.erb
<!DOCTYPE html>
<html>
<head>
<meta content="text/html; charset=UTF-8" http-equiv="Content-Type">
<title>PIPPO</title>
<meta content="yes" name="apple-mobile-web-app-capable">
<meta content="black-translucent" name="apple-mobile-web-app-status-bar-style">
<meta name="viewport" content="initial-scale = 1.0,maximum-scale = 1.0" />
<link href="/assets/login.css" media="all" rel="stylesheet" />
<script src="/assets/login.js"></script>
<%= csrf_meta_tags %>
</head>
<body>
<div class="main-content">
<%= yield %>
</div>
</body>
</html>
With the following controller
class SessionsController < ApplicationController
layout 'login'
...
def destroy
Session.find(session[:id]).close
reset_session
respond_to do |format|
flash[:success] = t('sessions.logout')
format.html { redirect_to login_url }
end
end
end
and routes
...
get 'login', to: 'sessions#new', as: 'login'
get 'logout', to: 'sessions#destroy', as: 'logout'
...
produces the following HTML once I click on <%= link_to 'logout', logout_path %>?
<head>
<meta content="text/html; charset=UTF-8" http-equiv="Content-Type">
<title>PIPPO</title>
<meta content="yes" name="apple-mobile-web-app-capable">
<meta content="black-translucent" name="apple-mobile-web-app-status-bar-style">
<meta name="viewport" content="initial-scale = 1.0,maximum-scale = 1.0" />
<link href="/assets/application.css" media="all" rel="stylesheet" />
<script src="/assets/application.js"></script>
<meta content="authenticity_token" name="csrf-param" />
<meta content="l9+umk+wjpXY4UFiKEeuQkGgMvjbbZ2uDxyJHowTJFo=" name="csrf-token" />
</head>
Am I missing anything here? It is two days I'm trying to figure this out.
Why is it using the head from the main layout instead of the one in login?
Thanks for your help.
UPDATE - Forgot to mention my log file states:
Rendered sessions/new.html.erb within layouts/login (1.4ms)
As per the layout name given in the question, i.e.,
app/views/layout.login.html.erb
There are couple of things wrong here:
layouts should be placed in app/views/layouts folder
File name should be login.html.erb and not layout.login.html.erb
In your case, Rails could not find login.html.erb in app/views/layouts, it rendered the default layout app/views/layouts/application.html.erb.
