Change the config values in Phalcon - phalcon

I have Config.ini file with the content
[episode]
unlock = false;
I want to change the value from the controller like
$this->config['episode'] = array('unlock' => true);
OR
$this->config->episode->unlock = true;
I have this on my loader file
$di->set('config', function() use($config){
return $config;
});

You'll have to get the config from your DI container first, then you can change values as much as you like.
$config = $this->di->get('config');
$config['episode'] = array('unlock' => true);
As mentioned in the comments, this works, but doesn't make that much sense, because the new value will not persist between requests.

How to export vuelayers map to png or jpeg?

How would I adapt #ghettovoice JSFiddle that saves a map to PDF to save the map to a JPEG or PNG? I have no idea how to attempt this problem so ideally if you know hoe to do it you can explain the logic behind it.
exportMap: function () {
var map = this.$refs.map
map.once('rendercomplete', function () {
var mapCanvas = document.createElement('canvas');
var size = map.getSize();
mapCanvas.width = size[0];
mapCanvas.height = size[1];
var mapContext = mapCanvas.getContext('2d');
Array.prototype.forEach.call(
document.querySelectorAll('.ol-layer canvas'),
function (canvas) {
if (canvas.width > 0) {
var opacity = canvas.parentNode.style.opacity;
mapContext.globalAlpha = opacity === '' ? 1 : Number(opacity);
var transform = canvas.style.transform;
// Get the transform parameters from the style's transform matrix
var matrix = transform
.match(/^matrix\(([^(]*)\)$/)[1]
.split(',')
.map(Number);
// Apply the transform to the export map context
CanvasRenderingContext2D.prototype.setTransform.apply(
mapContext,
matrix
);
mapContext.drawImage(canvas, 0, 0);
}
}
);
if (navigator.msSaveBlob) {
// link download attribuute does not work on MS browsers
navigator.msSaveBlob(mapCanvas.msToBlob(), 'map.png');
} else {
var link = document.getElementById('image-download');
link.href = mapCanvas.toDataURL();
link.click();
}
});
map.renderSync();
}
The problem was a combination of missing dependencies (namely FileSaver.js and fakerator.js) and a cross origin server block (CORS block) (Browsers automatically prevent httpRequests to a different domain name unless the server allows it). The first one is fixed by installing the packages while the second one is resolved by setting the crossOrigin Attribute of the ImageWMSLayer to null in my case but possibly to 'Anonymous' for other sources. Hope this helped someone else :)

KeystoneJS Cloudinary image upload

I am using the latest version of KeystoneJS and have a form working to add a record to the database.
I'm having trouble getting image uploads to work.
My model conatains:
heroImage: { type: Types.CloudinaryImage, autoCleanup : true },
My form includes:
<input type="file" accept="image/*" id="heroImage" name="heroImage_upload" className='field-upload'>
and my middleware for saving the form simply includes:
view.on('post', {action: 'save'}, function(next)
{
var newProperty = new Property.model(req.body);
console.log(newProperty);
newProperty.save(function(err, body)
{});
});
which works great for all field's except the file upload.
I've tried adding:
newProperty.heroImage = req.files['heroImage'];
which leaves heroImage as null.
I also tried creating a cloudinaryImage but this causes an error:
var img = new CloudinaryImage(req.files['heroImage']);
It all works fine when I use the KeystoneJS admin dashboard to upload images. Can someone please explain how I should use the cloudinaryImage field type in my own form?
Thanks
Not sure if this will help, but there is a note at the bottom of the docs:
http://keystonejs.com/docs/database/#fieldtypes-cloudinaryimage
"Remember that if you are uploading images to a CloudinaryImage field using an HTML form, you need to specify enctype="multipart/form-data" in your form tag."
Have you included that in your form?
Update:
So, the following should work, assuming your model is called MyModel, and your form data uses the same object keys as your model. (i.e. the image for your heroImage field should be provided as heroImage in the POST data).
var MyModel = keystone.list('MyModel');
view.on('post', {action: 'save'}, function(next)
{
var item = new MyModel.model();
data = req.body;
item.getUpdateHandler(req).process(data, function(err) {
// Handle error
}
}
Keystone should then handle all the specific cloudinary stuff internally.
Here is a way to do it with cloudinary.v2
untested keystone
cloudinary.v2.uploader.upload(base64_file_data, (err, result) => {
var newMyModel = new MyModel.model(model_data);
newMyModel.image = result;
let updater = newMyModel.getUpdateHandler(req);
updater.process(newMyModel, {
fields: image
}, err => {...})
})
tested mongoose
cloudinary.v2.uploader.upload(base64_file_data, (err, result) => {
var newMyModel = new MyModel.model(model_data);
newMyModel.image = result;
newMyModel.save(err => {...})
})

why using viewSimple renderer in Phalcon corrupts main renderer

First I declare simple view like this:
$di->set('viewSimple', function() {
$view = new \Phalcon\Mvc\View\Simple();
$view->setViewsDir('../app/views/');
$view->registerEngines(array(
".volt" => 'volt'
));
return $view;
});
then to generate html email, I use it as following:
public function renderHTMLEmail($template_name, $template_params) {
$content = $this->viewSimple->render("emails/$template_name", $template_params);
return $this->viewSimple->render("emails/master", array( 'content' => $content) );
}
My emails are being generated just fine, but whenever I call my renderHTMLEmail function actual page rendering is somehow corrupted and page appears totally blank (I have to use redirect as workaround). This is a mystery to me as main view renderer is completely different object. Can I prevent this?
Or does anybody have recommended method of generating arbitrary pieces of html outside of main view rendering process which would not interfere with it? There is couple of similar questions on SO, but none of solutions work. They either don't generate my email or they corrupt main view.
Found a solution, when registering the "\Phalcon\Mvc\View\Simple" component into the DI container make sure to use a new volt instance otherwise it will join up with the application's \Phalcon\Mvc\View volt instance somehow. This is what lot (https://stackoverflow.com/users/1672165/lot) was suggesting in the comments.
Code sample:
public function getTemplate($name, $params)
{
$parameters = array_merge(array(
'publicUrl' => $this->getDI()->getApp()->url->host . $this->getDI()->getApp()->url->baseUri
), $params);
$app = $this->getDI()->getApp();
$this->getDI()->set('simpleView', function() use ($app) {
$view = new \Phalcon\Mvc\View\Simple();
$view->setViewsDir(APP_DIR . $app->application->viewsDir);
$view->registerEngines(array(
".volt" => function ($view, $di) {
$volt = new \Phalcon\Mvc\View\Engine\Volt($view, $di);
$volt->setOptions(array(
'compiledPath' => APP_DIR . '/cache/volt/',
'compiledSeparator' => '_',
'compiledExtension' => '.compiled'
));
$compiler = $volt->getCompiler();
$compiler->addFunction('is_a', 'is_a');
return $volt;
}
));
return $view;
});
/* #var $simpleView \Phalcon\Mvc\View\Simple */
$simpleView = $this->getDI()->get('simpleView');
foreach ($parameters as $key => $value) {
$simpleView->{$key} = $value;
}
$html = $simpleView->render('emails/' . $name, $parameters);
return $html;
}
Sample was pulled straight from our working app so may need some re-working but should help solve the original issue.
This works for me using \View as the application DI registered view component which renders controller action volt views and the above \View\Simple with fresh volt registration successfully emails and allows the original view with volt to carry on.
This was asked a while ago however i've not seen a working solution anywhere else.
For completeness I've registered a github issue with the findings: https://github.com/phalcon/cphalcon/issues/3096
I recently had to deal with a similar problem, I'm not certain where you're falling short, but one important thing was to use a separate view from the one used by the application – you're already doing this. See if the following works.
protected function renderView($view, $template, array $data = null)
{
return $view
->reset()
->pick('emails/' . $template)
->setVars($data)
->start()
->render(null, null)
->finish()
->getContent();
}
public function renderHTMLEmail($template_name, $template_params)
{
$content = $this->render($template_name, $template_params);
return $this->render('master', array('content' => $content));
}

Is it possible to render custom view (just custom .phtml) template with Phalcon\Mvc\View?

I need to render email templates in variable to send them later (which are stored in .phtml files), and i really don't want to implement my special class for handling this.
Is it possible to render not controller action view, but custom one?
I tried following code, but it outputs NULL :((
// Controller context
$view = new Phalcon\Mvc\View();
$view->setViewsDir('app/views/');
$view->setVar('var1', 'var2');
// Setting some vars...
$view->start();
$view->partial($emailTemplatePath);
$view->finish();
$result = $view->getContent();
var_dump($result); // Gives null
In addition to the response by Nikolaos, you can use $view->getRender() to render a single view returning its output.
$view->setViewsDir('apps/views/');
echo $view->getRender('partials', 'test'); // get apps/views/partials/test.phtml
You need to check the path of the $emailTemplatePath. It should point to the correct file i.e.
// points to app/views/partials/email.phtml
$view->partial('partials/email');
If you are using Volt and have registered that as your engine, then your file will need to be:
// app/views/partials/email.volt
I have a project where I use email and pdf templates and what I did was to have the rendering all take place within components.
Firstly, my folder structure contains (and I will only put here what is relevant) a cache, components and views directory. Let's look at the email setup rather than the PDF as this is more relevant to your situation.
/app
/cache
/email
/components
/views
/email
/elements
Of course there is public, controllers etc but let's not think about them for this.
I'm using Swift mailer for mine but I hope you will be able to use this all the same. In /app/components/Swift.php I have a __construct that calls for this->init_template_engine();
/**
* Create a volt templating engine for generating html
*/
private function init_template_engine() {
$this->_template = new \Phalcon\Mvc\View\Simple();
$di = new \Phalcon\DI\FactoryDefault();
$this->_template->setDI($di);
$this->_template->registerEngines([
'.volt' => function($view, $di) {
$volt = new \Phalcon\Mvc\View\Engine\Volt($view, $di);
$volt->setOptions([
'compiledPath' => APP_DIR."cache".DS."email".DS, // render cache in /app/cache/email/
'compiledSeparator' => '_'
]);
return $volt;
// or use ".phtml" => 'Phalcon\Mvc\View\Engine\Php' if you want,
// both will accept PHP code if ya don't fancy it being a 100% volt.
},
]);
// tell it where your templates are
$this->_template->setViewsDir(APP_DIR.'views'.DS.'email'.DS);
return $this->_template;
}
The constants above (like APP_DIR) are something I have already made in my bootstrap and all they do is store full paths to directories.
Once the $_template variable has a template engine set up I can then use it to render my templates.
/**
* Returns HTML via Phalcon's volt engine.
* #param string $template_name
* #param array $data
*/
private function render_template($template_name = null, $data = null) {
// Check we have some data.
if (empty($data)) {
return false; // or set some default data maybe?
}
// Use the template name given to render the file in views/email
if(is_object($this->_template) && !empty($template_name)) {
return $this->_template->render($template_name, ['data' => $data]);
}
return false;
}
A sample volt email template may look like this:
{{ partial('elements/email_head') }}
<h2>Your Order has been dispatched</h2>
<p>Dear {{ data.name }}</p>
<p>Your order with ACME has now been dispatched and should be with you within a few days.</p>
<p>Do not hesitate to contact us should you have any questions when your waste of money arrives.</p>
<p>Thank you for choosing ACME Inc.</p>
{{ partial('elements/email_foot') }}
All I have to do then is grab the html and use swiftmailer's setBody method and I'm done:
->setBody($this->render_template($template, $data), 'text/html');
You don't need to place separate view engines like this in components, it could become memory hungry like that, but it does show the whole process. Hope that makes sense :)
The easiest way to render a view and return it as a variable is to use the Phalcon\Mvc\View\Simple class. In your controller, declare a new instance of the Simple view class and attach a rendering engine to it. You can then use its render() method to select a view file and pass in variables:
// create a simple view to help render sections of the page
$simple_view = new \Phalcon\Mvc\View\Simple();
$simple_view->setViewsDir( __DIR__ . '/../views/' );
$simple_view->setDI( $this->di );
$simple_view->registerEngines(array(
'.volt' => 'Phalcon\Mvc\View\Engine\Volt'
));
// use the simple view to generate one or more widgets
$widget_html = array();
$widget_objects = $widget_search->getWidgetObjects();
forEach( $widget_objects as $widget ){
$widget_html[] = $simple_view->render('index/widgetview',array('widget'=>$widget));
}
// pass the html snippets as a variable into your regular view
$this->view->setVar('widget_html',$widget_html);
use $view->render('partials/email') instead of calling partial method.
I usually use Volt engine and a simple way is a redefine view in DI container, like that:
$view = $this->view;
$content = $view->getRender('mail', 'show',
array(
"var1" => "some value 1",
"var2" => "some value 2"
),
function($view) {
$view->setRenderLevel(\Phalcon\Mvc\View::LEVEL_LAYOUT);
}
);
echo $content;

How do you delete files before they have been uploaded by the dojo Multifile Uploader?

I am using a dojox.form.uploader.FileList here: https://github.com/chotchki/pgGallery/blob/master/src/main/webapp/WEB-INF/views/gallery/gallery.jsp#L129
I have looked through the API documentation and can't find a way to allow the user to remove a file from the list to be uploaded before they click upload.
Any ideas?
I found no solution too, so i wrote this little hack, it just extending dojox/form/Uploader. So far it seems to work for me, at least in Firefox. It adds a method removeFile(index) and a onRemove(file) method to the Uploader class.
What you need to do is use force="iframe" on your uploader Element or set the property on your object.
require(["dojo/_base/lang","dojox/form/Uploader","dojo/dom-construct","dojo/_base/array"],function(lang, Uploader, domConstruct, array){
lang.extend(Uploader,{
removeFile: function(index){
if(this._inputs.length > index){
//Delete input field from dom
domConstruct.destroy(this._inputs[index]);
//Delete file From input Array
var _arr = new Array();
var _file = this._inputs[index];
array.forEach(this._inputs,function(n,i){
if(i != index){
_arr.push(n);
}
});
this._inputs = _arr;
this.onRemove(_file);
}
},
onRemove: function(file){
}
});
});
