I'm trying to connect assetic with Twig (on Zend). It seems to work ok for debug=false, but I cannot understand what it does for development.
Basically, when calling this:
{% javascripts 'static/js/*.js' %}
<p>{{asset_url}}</p>
{% endjavascripts %}
it outputs a list of generated javascript file names (which is nice):
js/d19cc07_part_1_jquery-1.7.2.min_6.js
js/d19cc07_part_1_jquery.cookie_7.js
js/d19cc07_part_1_jquery.jeditable.mini_8.js
but these files are not generated by writter (it only generates js/d19cc07.js). For debug=false it outputs just one file name and also renders it correctly.
So what am I missing here?
Here's how I initialize it:
//Assetic
$factory = new \Assetic\Factory\AssetFactory(APP_BASE_PATH . '/public/');
$factory->setDebug(true);
$am = new \Assetic\Factory\LazyAssetManager($factory);
//enable loading assets from twig templates
$loader = new \Twig_Loader_Filesystem(array());
$loader->addPath(APP_BASE_PATH.'/application/templates/default');
//Init twig
$twig = new \Twig_Environment($loader);
$twig->addExtension(new \Assetic\Extension\Twig\AsseticExtension($factory));
$am->setLoader('twig', new \Assetic\Extension\Twig\TwigFormulaLoader($twig));
$templates = array('/index/index.html'); //An array containing full paths to my templates
foreach ($templates as $template) {
$resource = new \Assetic\Extension\Twig\TwigResource($loader, $template);
$am->addResource($resource, 'twig');
}
//Writer
$writer = new \Assetic\AssetWriter(APP_BASE_PATH . '/public/static/assetic');
$writer->writeManagerAssets($am);
echo $twig->render('index/index.html');
I ended up connecting Symfony console to my Zend project and slightly adopting DumpCommand from assetic to make this work (by passing my version of DI containter with assigned AsseticManager).

I am working on a piece of software that uses libxml to store xml on webpages in an xmlDocPtr. I need to expand this functionality to do the same for html.
The original code:
xmlDocPtr doc = xmlParseEntity(filename.c_str());
Where filename = 10.1.1.135/poll_data.xml and everything works just fine
Now, I have html filename = 10.1.1.165/index.htm and would like to store this as well. I have tried using htmlParseDoc with no success.
htmlDocPtr doc = htmlParseFile(filename.c_str(), "windows-1252");
The resulting doc object is not null but it does not contain the contents of the index.html
Netbeans spits out:
http://10.1.1.165/index.htm:1: HTML parser error : Document is empty
Any suggestions?
I've been looking into source code of Research Kit Example called ORKTest:
if (type.integerValue == ORKConsentSectionTypeDataGathering) {
/*
Tests PDF content instead of text, HTML for Learn More.
*/
NSString *path = [[NSBundle mainBundle] pathForResource:#"SAMPLE_PDF_TEST" ofType:#"pdf"];
consentSection.contentURL = [NSURL URLWithString:path];
}
It used a local PDF file path in .contentURL,and I'd like to replace it with a online PDF url such as http://examle.com/file/example.pdf
consentSection.contentURL = NSURL.fileURLWithPath("http://example.com/file/example.pdf")
or
consentSection.contentURL = NSURL.fileURLWithPath("example.com/file/example.pdf")
but only got an empty page(the url that I used worked fine on browser,just a pdf file).
Anyone got any ideas,please?
NSURL.fileURLWithPath only works with local files. You have to put it in app's sandbox, then ask consentSection to load it.
Let me start by saying I have absolutely no idea what I should be doing because the documentation and available information on Assetic is either limited or Symfony oriented.
Here is my folder structure.
Assetic
+ assets
+ css
+ example.css
+ docs
+ src
+ tests
+ vendor
+ index.php
+ styles.php
Now, I have the following test code. Basically I cloned a clean copy of Assetic and ran composer install. Then I create an index.php file which simply links to my styles.php file with HTMLs <link> tag.
Here is my styles.php
<?php
require 'vendor/autoload.php';
$assetPath = __DIR__.'/assets/css/example.css';
$assetBasePath = __DIR__.'/assets/css';
$asset = new Assetic\Asset\FileAsset($assetPath, array(), $assetBasePath, 'example.css');
header('Content-Type: text/css');
$asset->setTargetPath(__DIR__);
echo $asset->dump(new Assetic\Filter\CssRewriteFilter);
Here is my example.css stylesheet.
body {
background-image: url('../img/background.png');
}
When I load up the styles.php in my browser I get the following output.
url('../img/background.png');
That's the same as the actual CSS. If I use the CSS URI Rewriter from Mr. Clay I get the expected output.
url('/Assetic/assets/img/background.png');
So what am I doing wrong with Assetic? I have no idea what paths I should be passing in and to where.
Thanks.
Just a pretty hard time with it, but finally (after reading the doc. of webassets, python library on which assetic is based) I won over the lack of documentation.
Here you go
<?php
require 'vendor/autoload.php';
$assetPath = __DIR__.'/assets/css/example.css';
$asset = new Assetic\Asset\FileAsset($assetPath, array(new Assetic\Filter\CssRewriteFilter), dirname($assetPath), '/assets/css');
// I assume the 'assets' directory is at the root of your website
header('Content-Type: text/css');
$asset->setTargetPath('/path/to/dumped/asset');
// As above, it's the path to the generated asset from your http root
echo $asset->dump();
I'm not sure to be very clear, so ask if you didn't understand something.
I got problem when implementing my CMS using Codeigniter 1.7.2 and Dwoo. I use Phil Sturgeon Dwoo library. My problem is I want user create template from the admin panel, it means all template will be stored into database including all Dwoo variable and functions.My questions:
Is it possible to load dwoo template from database?
How to parse dwoo variable or function from database? I tried to load content from database which is include dwoo var and function inside it, and i have tried to do evaluation using dwoo eval() function and phil sturgeon string_parse() but still have no luck.
for example:
my controller
$data['header'] = "<h1>{$header}</h1>"; --> this could be loaded from database
$this->parser->parse('header',$data);
my view
{$header}
This is the error message:
<h4>A PHP Error was encountered</h4>
<p>Severity: Notice</p>
<p>Message: Undefined index: header_title</p>
<p>Filename: compiled/805659ab5e619e094cac7deb9c8cbfb5.d17.php</p>
<p>Line Number: 11</p>
header_title is dwoo variable that loaded from DB.
Thank you,
It is definitely possible to do this, but for performance reasons it would probably be faster to store the templates as files on the filesystem, even if they're edited by users. If you're smart with file naming you can avoid most hits to the database.
Anyway, if you really want to do it with the database, the following should work:
// rendering the header
$template = '<h1>{$header}</h1>'; // loaded from db, don't use double-quotes for examples or $header will be replaced by nothing
$data = array('header' => 'Hello'); // loaded from db as well I assume
$headerOutput = $this->parser->parse_string($template, $data, true); // true makes it return the output
// now rendering the full page (if needed?)
$data = array('header' => $headerOutput);
$this->parser->parse('header', $data); // no 'true', so goes straight to output
The view would then contain {$header} and the output from the header template is passed to that variable.
Now I'm not sure how CI works so it might be better to just output the result of the first template and skip the second one entirely, but I'll leave that up to you.
I am using both Zend framework and Django, and they both have they strengths and weakness, but they are both good framworks in their own way.
I do want to create a highly modular web application, like this example:
modules:
Admin
cms
articles
sections
...
...
...
I also want all modules to be self contained with all confid and template files.
I have been looking into a way to solve this is zend the last days, but adding one omer level to the module setup doesn't feel right. I am sure this could be done, but should I? I have also included Doctrine to my zend application that could give me even more problems in my module setup!
When we are talking about Django this is easy to implement (Easy as in concept, not in implementation time or whatever) and a great way to create web apps. But one of the downsides of Django is the web hosing part. There are some web hosts offering Django support, but not that many..
So then I guess the question is what have the most value; rapid modular development versus hosting options!
Well, comments are welcome!
Thanks
You can implement sub-modules with relatively little effort in ZF. Let's say you have directory structure such as:
application/
modules/
admin/
cms/
controllers/
views/
controllers/
views/
You'd register the modules like this in your bootstrap (sub-modules use _ to separate the sub-module from the main module):
$frontController->setControllerDirectory(array(
'default' => APPLICATION_PATH . '/modules/default/controllers',
'admin' => APPLICATION_PATH . '/modules/admin/controllers',
'admin_cms' => APPLICATION_PATH . '/modules/admin/cms/controllers'
));
The issue with this is that it would actually use an underline in the URL instead of a slash, so eg: "admin_cms/conteroller/action" instead of "admin/cms/controller/action". While this "works", it's not pretty. One way to solve the issue is to provide your own route for the default route. Since the default Zend_Controller_Router_Route_Module does it almost right, you can simply extend from it and add the wanted behavior:
<?php
class App_Router_Route_Module extends Zend_Controller_Router_Route_Module
{
public function __construct()
{
$frontController = Zend_Controller_Front::getInstance();
$dispatcher = $frontController->getDispatcher();
$request = $frontController->getRequest();
parent::__construct(array(), $dispatcher, $request);
}
public function match($path)
{
// Get front controller instance
$frontController = Zend_Controller_Front::getInstance();
// Parse path parts
$parts = explode('/', $path);
// Get all registered modules
$modules = $frontController->getControllerDirectory();
// Check if we're in default module
if (count($parts) == 0 || !isset($modules[$parts[0]]))
array_unshift($parts, $frontController->getDefaultModule());
// Module name
$module = $parts[0];
// While there are more parts to parse
while (isset($parts[1])) {
// Construct new module name
$module .= '_' . $parts[1];
// If module doesn't exist, stop processing
if (!isset($modules[$module]))
break;
// Replace the parts with the new module name
array_splice($parts, 0, 2, $module);
}
// Put path back together
$path = implode('/', $parts);
// Let Zend's module router deal with the rest
return parent::match($path);
}
}
And in your bootstrap:
$router = Zend_Controller_Front::getInstance()->getRouter();
$router->addRoute('default', new App_Router_Route_Module);
What this does is traverse the path as long as it finds a module, and transparently rewrites the path so that the default Zend_Controller_Router_Route_Module can do the real work. For example the following path: "/admin/cms/article/edit" will be transformed into "/admin_cms/article/edit", which allows the standard convention of the ZF's ":module/:controller/:action" do the magic.
This allows you to have nice modular structure with self-contained modules, while still use pretty, logical URLs. One thing you want to make note of is that if you use Zend_Navigation and specify the navigation items using module/controller/action parameters, you need to tell ZF how to correctly build the URL using "/" instead of "_" in module names (by default ZF uses the :module/:controller/:action spec when it builds the URLs). You can do this by implementing your own Zend_Controller_Action_Helper_Url, like this:
<?php
class App_Router_Helper_Url extends Zend_Controller_Action_Helper_Url
{
public function url($urlOptions = array(), $name = null, $reset = false, $encode = false)
{
// Replace the _ with / in the module name
$urlOptions['module'] = str_replace('_', '/', $urlOptions['module']);
// Let the router do rest of the work
return $this->getFrontController()->getRouter()->assemble($urlOptions, $name, $reset, $encode);
}
}
And in your bootstrap:
Zend_Controller_Action_HelperBroker::addHelper(new App_Router_Helper_Url);
Now Zend_Navigation works nicely with your sub-module support as well.
I (despite of being happy ZF user) would go for Django. In ZF the "fully-modular" application is kind of holly grail. It's nearly impossible (or at least without extreme effort) to create selfcontained modules, instalable like "copy this folder into your modules directory" :) Not sure about Django, but from what I head it's simplier there...
