I am using Python 3. I have created the necessary folders. i.e. static and templates folder. Still, this code is not working. I get the following error werkzeug.exceptions.BadRequestKeyError
abc.py

Your form action is set to ""
change it to this:

Everytime i tried to use for loop in the PyScript tag, getting an invalid Syntax error :/.What i want to do is (for example):
Python:
attr1=['A','B','C']
for i in attr1:
pyscript.write('output1',i)
HTML:
<div id='output1'></div>
You can just write to the document with print, it doesn't leave you with much choice about the tags for now though. For example,
<!doctype html>
<html>
<head>
<title></title>
<meta charset="utf-8" />
</head>
<body>
<link rel="stylesheet" href="https://pyscript.net/alpha/pyscript.css" />
<script defer src="https://pyscript.net/alpha/pyscript.js"></script>
<py-script>
l = ["A", "B", "C"]
for el in l:
print(el)
</py-script>
</body>
</html>
Will show
A
B
C
in the browser.
and it actually generates the following:
<html><head>
<title></title>
<meta charset="utf-8">
<script src="https://cdn.jsdelivr.net/pyodide/v0.20.0/full/pyodide.js"></script></head>

<!DOCTYPE html>
<html lang="en" xmlns:th="http://www.thymeleaf.org">

<title>Hello Thymeleaf!</title>
</head>
<body>
<p th:text="'Hello, ' + ${name} + '!'" />
<img th:src="#{data:image/jpeg;base64, /9j/4AAQSkZJRgABAgAAAQABAAD/7QCEUGhvdG9zaG9wI...
}">
</body>
</html>
I am displaying an image which is converted to Base64 (MIME type conversion) format and I am using Thyme-leaf template, can someone figure out what's happening?
One possible error could be that thymeleaf check the html-syntax strict and you don't close your image-tag. So try to change it like this:
<img th:src="#{data:image/jpeg;base64, /9j/4AAQSkZJRgABAgAAAQ... }" />
I'm following this tutorial: http://www.thymeleaf.org/doc/layouts.html (got to Thymeleaf Layout Dialect section).
In there you can find an example:
<!DOCTYPE html>
<html>
<head>
<!--/* Each token will be replaced by their respective titles in the resulting page. */-->
<title layout:title-pattern="$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.
I have two layouts and both are working in index page, but when I give to another the second one doesn't work. I don't know what the problem is, I'm new to tapestry.
my code is
<html t:type="layout1" title="accountInfo VideoClub"
xmlns:t="http://tapestry.apache.org/schema/tapestry_5_1_0.xsd"
xmlns:p="tapestry:parameter">
<head>
<meta content="yes" name="apple-mobile-web-app-capable"/>
<meta content="black" name="apple-mobile-web-app-status-bar-style"/>
<meta content="text/html; charset=UTF-8" http-equiv="content-type"/>
<meta content="width=device-width; initial-scale=1.0; maximum-scale=1.0;
user-scalable=0;" name="viewport" />
<title>Video Club</title>
<link href="./layout/layout.css" type="text/css" rel="stylesheet" />
</head>
<body>
<div id="wrap">
<div id="scroll">
<ul id="thelist">
<div style="text-align:center;">
<p><h1>Account info</h1>
<t:actionlink t:id="getStatus"> <img src="../layout/images
/sub.png"/>
</t:actionlink><br/><br/>
<t:actionlink t:id="getStatuss"> <img src="../layout/images
/cancel_sub.png"/> </t:actionlink><br/></p>
</div>
</ul>
</div>
</div>
</body>
</html>
Without the entire code (tml and java) we can't help you much.
Layout components in tapestry are plain components, which render their body with some content around it.
Please paste your code here.
