I am trying to use ember-index add on to generate index.jsp file instead of index.html. I have installed the ember-index addon and did the required changes as well.
My config/environment.js file looks like below
/* eslint-env node */
'use strict';
module.exports = function(environment) {
let ENV = {
modulePrefix: 'user-profile',
output: 'index.jsp',
environment,
rootURL: '/',
locationType: 'hash',
EmberENV: {
FEATURES: {
// Here you can enable experimental features on an ember canary build
// e.g. 'with-controller': true
},
EXTEND_PROTOTYPES: {
// Prevent Ember Data from overriding Date.parse.
Date: false
}
},
'ember-index': {
output: 'index.jsp',
content: {
file: 'example.txt',
includeInOutput: true,
includeInIndexHtml: false
}
},
APP: {
// Here you can pass flags/options to your application instance
// when it is created
}
};
return ENV;
};
Also my example.txt file looks like
<meta content="Example">
<h2>html to jsp</h2>
and finally in my index.html I have added below snippet
{{content-for 'ember-index'}}
But now when i am trying to build the ember project with ember build I am not able to see index.jsp file in my dist folder.
With a fresh app, this addon works as expected. Walk through the steps for the minimal example using a new Ember app, and you'll find what you missed.
Are you sure you're looking in the right place for the index.jsp? It is at dist/export/index.jsp after running ember build.
Did you forget to add the tag in your index.html? The readme specifies that for your files to be used, they must be specified like this:
<!-- app/index.html -->
<!DOCTYPE html>
<html>
<head>
...
{{content-for 'ember-index-1'}}
{{content-for 'ember-index-2'}}
</head>
<body>
...
</body>
</html>
Using:
WKpdftohml version 0.12.3.2
PHPwkhtmltopdf version 2.2.0
Chart.JS version 2.5.0
I'm trying to print a line graph using the above libraries. I can reproduce a pdf using the shell command: wkhtmltopdf --javascript-delay 5000 " http://netdna.webdesignerdepot.com/uploads7/easily-create-stunning-animated-charts-with-chart-js/chartjs-demo.html" test2.pdf
So there is no problem with WKhtmltopdf.
The problem is when I do it in my app, using the PHPwkhtmltopdf library. I get a blank page.
From my research these are the things I tried:
Added 'javascript-delay' => 500 to Chart.JS options;
Added animation:{onComplete: function () {window.JSREPORT_READY_TO_START =true} to Chart.JS options;
Added <div style="width:800px;height:200;font-size:10px;"> to the parent div of canvas html tag
Added ctx.canvas.width = 800;ctx.canvas.height = 200; to javascript initialization of the chart.
Well nothing worked. I love Chart.JS and WKhtmltopdf, but if I can't print I'll have to drop one of them. Is there any solution?
This is my php code for the PHPwkhtmltopdf:
public function imprimir ($request, $response)
{
// include_once 'config/constants.php';
// include_once 'resources/auxiliar/helpers.php';
$folha = $_POST['printit'];
$variaveis = explode(',', $folha);
$nomeFicheiro = $variaveis[0];
$printName = substr($nomeFicheiro, 5);
if (isset($variaveis[2])) {
$_SESSION['mesNumero'] = $variaveis[2];
$_SESSION['mes'] = $variaveis[1];
} else {
$mesNumero = 0;
$mes = '';
}
ob_start();
if ($nomeFicheiro == 'printPpiam') {
require ('C:/xampp/htdocs/.../'.$nomeFicheiro.'.php');
} else {
require ('C:/xampp/htdocs/.../'.$nomeFicheiro.'.php');
}
$content = ob_get_clean();
// You can pass a filename, a HTML string, an URL or an options array to the constructor
$pdf = new Pdf($content);
// On some systems you may have to set the path to the wkhtmltopdf executable
$pdf->binary = 'C:/Program Files/wkhtmltopdf/bin/wkhtmltopdf';
$pdf -> setOptions(['orientation' => 'Landscape',
'javascript-delay' => 500,
// 'enable-javascript' => true,
// 'no-stop-slow-scripts' => true]
]);
if (!$pdf->send($printName.'.pdf')) {
throw new Exception('Could not create PDF: '.$pdf->getError());
}
$pdf->send($printName.'.pdf');
}
# Update 1
Made a php file with the page output. Run it in the browser and the graph rendered. When I do it in the console it renders everything except the graph!
How can it be wkhtmltopdf renders the graphics in this page : http://netdna.webdesignerdepot.com/uploads7/easily-create-stunning-animated-charts-with-chart-js/chartjs-demo.html but not my own?!
# Update 2
After Quince's comment, I tried just turning the animations off, but I'm not sure on how to do that. I tried:
$pdf -> setOptions(['orientation' => 'Landscape',
'javascript-delay' => 500,
// 'window-status' => 'myrandomstring ',
'animation' => false,
'debug-javascript',
'no-stop-slow-scripts',
]);
But it fails.
Here's the code that works with wkhtmltopdf version 0.12.5:
chart.html
<!DOCTYPE html>
<html lang="en">

(function(setLineDash) {
CanvasRenderingContext2D.prototype.setLineDash = function() {
if(!arguments[0].length){
arguments[0] = [1,0];
}
// Now, call the original method
return setLineDash.apply(this, arguments);
};
})(CanvasRenderingContext2D.prototype.setLineDash);
Function.prototype.bind = Function.prototype.bind || function (thisp) {
var fn = this;
return function () {
return fn.apply(thisp, arguments);
};
};
function drawGraphs() {
new Chart(
document.getElementById("canvas"), {
"responsive": false,
"type":"line",
"data":{"labels":["January","February","March","April","May","June","July"],"datasets":[{"label":"My First Dataset","data":[65,59,80,81,56,55,40],"fill":false,"borderColor":"rgb(75, 192, 192)","lineTension":0.1}]},
"options":{}
}
);
}
window.onload = function() {
drawGraphs();
};
</script>
</body>
</html>
Run:
$ wkhtmltopdf chart.html chart.pdf:

Resolving links (4/6)
Loading headers and footers (5/6)
Printing pages (6/6)

Found the answer. After I created a separate file, outside the framework, i did some tests again. It rendered the graph in the browser so I tried to use the command tool WKhtmltopdf, and it did not worked, when it did with other examples (see Update #1). So there is something wrong with my php page.
Ran the same tests that I did in the framework, and got the answer for my problem. By introducing a parent div tag width dimensions in the canvas tag it made the graph render in the page.
<div style="width:800px;height:200;">
<canvas id="myChart" style="width:800px;height:200;"></canvas>
</div>
The proposition was found in this site: Github, so thanks laguiz.
Try adding this, as according to this github source
<script src="https://cdnjs.cloudflare.com/ajax/libs/babel-polyfill/7.0.0/polyfill.min.js"></script>
Solved it by downgrading wkhtmltopdf: 0.12.4 > 0.12.2.1
chart.js version seemed to have no influence. I used 2.7.0.
Fixed width and height seem to be required as well.
Edit: Since wkhtmltopdf is dead, I switched to Puppeteer recently.
I was dealing with the same issue using rotativa to export my ASP.NET MVC page with Chart.JS to PDF with no luck.
After a couple of days I finally found a super-easy solution to achieve my goal. What I did is simply to use the .toBase64Image() method of Chart.JS to encode the chart to a base64 string variable in Javascript. Then I saved this string into a model and then on the PDF html page a used tag where i put the base64encoded string to a scr property and the result is great :-)
javascript:
//save Chart as Image
var url_base64 = document.getElementById('myChart').toDataURL('image/png');
//set the string as a value of a hidden element
document.getElementById('base64graph').value = url_base64;
PDF view:
<img style='display:block; width:900px;height:400px;position:relative;margin:auto;text-align:center;' id='base64image'
src='#Model.base64graph' />
I'm trying to improve on the answer by temuri, which is great, but a bit bloated. I ran into the OP's issues (even same WKpdftohml version) and this did the trick for me:
<script src="https://cdnjs.cloudflare.com/ajax/libs/Chart.js/2.8.0/Chart.min.js"></script>
<div style="width: 400px;"><canvas id="canvas"></canvas></div>
<script type="application/javascript">
// wkhtmltopdf 0.12.5 crash fix.
// https://github.com/wkhtmltopdf/wkhtmltopdf/issues/3242#issuecomment-518099192
Function.prototype.bind = Function.prototype.bind || function (thisp) {
const fn = this;
return function () {
return fn.apply(thisp, arguments);
};
};
new Chart(
document.getElementById("canvas"), {
"responsive": false,
"type":"line",
"data":{"labels":["January","February","March","April","May","June","July"],"datasets":[{"label":"My First Dataset","data":[65,59,80,81,56,55,40],"fill":false,"borderColor":"rgb(75, 192, 192)","lineTension":0.1}]},
"options":{}
}
);
</script>
I'm yet to figure out how to get the chart library via ordinary tools like npm, instead of getting it via ajax like here in the first line. Note that this can impact your chart resolution.
I was strugling with that too and you self-answer did not help my case. I am using symfony 3.3 and Chart.js 2 and whatever I did, did not work properly. So I have solved it in a different manner (maybe not a clean one) and I wanted to post it here for inspiration to others.
I needed to export a page, that I was presenting to the user in a browser. In browser, I used Javascript to get picture out of the rendered graph with
animation: {
onComplete: function(animation) {
console.log('done');
var url=document.getElementById("barChartByCountryWeight{{ part }}{{ subsetKey }}").toDataURL();
$.ajax({
url: 'saveChartImages',
type: 'POST',
data: { 'barChartByCountryWeight{{ part }}{{ subsetKey }}': url },
success: function(result) {
console.log(result);
console.log('the request was successfully sent to the server');
},
error: function (request, error) {
console.log(arguments[0]['responseText']);
console.log(" Can't do because: " + error);
}
});
}
}
And on server side I put it in session and in a controller for the PDF export, I have taken the image from session and put the image in the HTML, that is converted to PDF.
Hope that helps.
I have implemented the working code for this issue. You can check out the working code here.
NOTE: For generating pdf you must disable the Chart JS animation or add the option javascript-delay=>1000 to the wkhtmltopdf options.
I have solved this problem when I tried to use Chartjs 1 instead of a new chart js. The reason for this is because laravel snappy uses wkhtmltopdf, which doesn't support css animation, while new chartjs uses css animation.
This github issue shows that.
The solution i found is to use google chart instead. It also uses svg, so you can get high resolution charts.
So I am using django-wysiwyg-redactor==0.4.9 and Django==1.9.
The issue described here.
I tried a trick in comments, but that didn't help.
Also in browser's console I run this code directly to needed textarea:
$('#id_outboundprogram_set-2-text').trigger('redactor:init');
But anyway there are no redactor on it.
Textarea element looks like this before and after running above code:
<textarea class=" redactor-box" cols="40" data-redactor-options="{"lang": "en", "fileUpload": "/en/redactor/upload/file/", "imageUpload": "/en/redactor/upload/image/", "plugins": ["table", "video"]} id="id_outboundprogram_set-2-text" name="outboundprogram_set-2-text" rows="10"></textarea>
Strange thing is that this code, that I found in jquery.redactor.init.js from package files is not working:
// Initialize Redactor on admin's dynamically-added inline
// formsets.
//
// Credit to the approach taken in django-selectable:
// https://github.com/mlavin/django-selectable
$(document).on('click', '.add-row', function () {
$(this).parents('.inline-related')
.find('tr.form-row:not(.empty-form)').last()
.find('textarea.redactor-box')
.trigger('redactor:init');
});
Any ideas?
UPD:
Well, I still don't know why it happpens, but I solved this problem by including redactor.js file from package files and adding a little changes to above script:
<script type="text/javascript" src="{% static 'js/admin/redactor.js' %}"></script>
var program_tab = $('#outboundprogram_set-group'); // this is just because I have several inlines
program_tab.children('.add-row').on('click', function(){
program_tab.children('.inline-related:not(.empty-form)')
.last()
.find('textarea.redactor-box')
.redactor();
});
UPD 2:
Using this soution there is no plugins and image/file handlers. So I researched a little and found this article.
But image and file handling already implemented in django-wysiwyg-redactor, so I need just to use RedactorUploadView(). Urls can be found in urls.py file from sources. So here is the code:
var program_tab = $('#outboundprogram_set-group');
program_tab.children('.add-row').on('click', function(){
program_tab.children('.inline-related:not(.empty-form)')
.last()
.find('textarea.redactor-box')
.redactor({
imageUpload: "{% url 'redactor_upload_image' 'tours/out/programs/img/' %}",
fileUpload: "{% url 'redactor_upload_file' 'tours/out/programs/files/' %}",
plugins: ['table', 'video', 'fullscreen', 'image']
});
});
I'm trying to change the roolURL in an Ember CLI app. This is easy in a basic Ember app:
App.Router.reopen({
rootURL: '/blog/'
});
Doing this in an Ember CLI app throws the following exception:
Uncaught TypeError: Cannot read property 'reopen' of undefined
The reason why I'd like to do this is that I'm going to have multiple Ember CLI apps inside of a rails app. The URLs will look something like this:
/ --> rails
/foo --> rails
/api --> rails
/admin --> Ember CLI
/blog --> Ember CLI
You'd want to update your config/environment.js as follows:
module.exports = function(environment) {
var ENV = {
environment: environment,
baseURL: '/blog/'
see http://www.ember-cli.com/#deployments for environment specific configurations.
I try to integrate the Minicolor JQuery component in Ember.js application.
Integration should be easy but it does not work for me... (input is displayed but without JQuery component)...
Minicolor integration guide:
https://github.com/claviska/jquery-miniColors
From doc: simply insert the js file and add the following input:
My js file:
App.ColorPicker = Em.TextField.extend({
type: 'minicolors',
attributeBindings: ['name'],
willInsertElement: function() {
;
}
});
The html file
{{view App.ColorPicker placeholder="Background color" name="color" valueBinding="App.MyController.backgroundColor"}}
I believe your issue is that ember is dynamically adding the <input type='minicolors' ... /> element after the initialization code for minicolors has already executed, causing your new minicolors input to not be initialized.
I got your example working by using the didInsertElement event instead of willInsertElement event to force minicolors to create the dynamically added App.ColorPicker element. The willInsertElement fires when the element is going to be inserted, but hasn't yet, and the didInsertElement will fire after the element has been inserted. I used the latest files from the minicolors github repository.
App.ColorPicker = Em.TextField.extend({
type: 'minicolors',
attributeBindings: ['name'],
didInsertElement: function() {
$.minicolors.init();
}
});
The only other issue I had was needing to make sure the css file and the png with the color picker graphical elements could be loaded. Apparently if the css and png files are not loadable the js portion doesn't work.
