Basically what I want to do is to create a SilverStripe CMS that allows users to enter information. Instead of displaying this information on a webpage like normal I want to output it using JSON to a hybrid mobile app. I know I have to use the RESTful server API and dataobjects but I'm a little unclear about how it will actually work.
Would appreciate a little enlightenment on this.
Saving the data into the database is very easy, this is even covered in one of the 5 basic tutorials.
Providing this information via REST isn't that hard either, if you just need basic functionality.
SilverStripe already comes with REST support, but at least in 2.4 this REST support is rather limited and really closely tied to the database model.
As far as I can tell, the REST Server has been removed in SS 3.0
Here a link to the API docs on the RestfulServer class in SS 2.4: http://api.silverstripe.org/2.4/sapphire/api/RestfulServer.html#class_details
as taken from that docs, its rather simple to allow api access to objects:
class Article extends DataObject {
static $db = array('Title'=>'Text','Published'=>'Boolean');
static $api_access = array(
'view' => array('Title'),
'edit' => array('Title'),
);
}
and than access it via http://mysite.com/api/v1/Article
If this does not cover your needs, I see 2 alternatives you could take:
Create your own Controller that outputs the rest stuff you need
Or, if you require a complex API, then use a REST framework like https://github.com/Luracast/Restler (but it might be a pain to set up Rester to work within SilverStripe because both, Restler and SS do there own URL magic)
Alternatively you can actually just spit out snippets of HTML. I have done this in several Phonegap apps. The styles, main javascript, etc are obvisouly embeded in the phonegap app. But you can create mini windows(almost like and iframe) that just get the HTML snippet. And conviently you can alter that HTML with your templates(very handy for changes).
Check out JQmobi framework and the data-defer feature.
You would just put the attribute of the data-defer to a URL on your site, and that URL is only an HTML snippet.

I have a new multi-tenant web application in ASP.NET Core 2.0, single DB.
I've established a method of determining a particular request's 'TenantId' by examining the domain in a simple piece of middleware.
I've also established a DataContext which applies TenantId filters to applicable tables as needed.
The last thing I'm unclear about is how I can differentiate Views/partial views based on the TenantId whilst sharing the controllers.
I think some scheme where the app first looks in some kind of TenantId sub-folder for the customized tenant's view and if it can't find it, it goes through the regular steps to locate the view... might work okay? Is this a reasonable approach? In other words, it should use the specialized tenant view if it exists, otherwise use the default view.
Would this involve building a custom view engine of sorts?
I've tried something similar with tenant based Html fragments, but it was a pain maintaining it, so I'm looking for something more straight forward on this project.
I'm open to other suggestions of how to implement this functionality as well.
Thanks in advance!
You don't need a whole custom viewengine, you can implement an IViewLocationExpander to make it check various locations for views.
In my project I have mutliple tenant support with both shared themes and tenant specific themes. I can override any view by dropping a copy below the theme folder, ie the main view could be Views/SiteAdmin/Index and I can override it in /pathtothemes/themefolder/SiteAdmin/Index
You can see my implementation of IViewLocationExpander here.
How you register your IViewLocationExpander is like this:
services.AddMvc()
.AddRazorOptions(options =>
{
options.ViewLocationExpanders.Add(new cloudscribe.Core.Web.Components.SiteViewLocationExpander());
})
.SetCompatibilityVersion(CompatibilityVersion.Version_2_1)
;
I'm developing a system where a Phalcon server is responsible for a site frontend while a Symfony2 server is responsible for the content management. The content manager contains an WYSIWYG editor and thus displays the content using the same layout and style as the frontend. I realize Volt and Twig and very similar, but some things like includes and blocks have specific syntax or limitations. We can create our templates/themes in a way that is completely compatible, but that would not be very flexible.
Is there a way to use Volt templates in Symfony2? Or a practical way to convert templates automatically (by hand is not an option here)?
I think in your specific use case the most practical would be to use Twig with Phalcon. In your DI you can load a different engine for that, see the Phalcon Incubator project for the Twig-adapter.
In short it comes down to using (after adding the Incubator to your project, for instance with Composer):
$view->registerEngines(
array(".twig" => 'Phalcon\Mvc\View\Engine\Twig')
);
instead of
$view->registerEngines(array(
".volt" => 'Phalcon\Mvc\View\Engine\Volt'
));

Every tutorial/example i can find for meteor shows a single view application. I would like to build something a little more complex. I'm unclear how to approach multiple views...preferably in a way that's somewhat scalable?
The iron-router package lets you access different views (layouts) by nice, REST-ful human-friendly clean URLs. It supports parameters in the URL, "loading" templates, waiting for subscriptions to finish loading, before and after hooks etc.
At this point you can only create Single Page applications with Meteor. Note that Single Page, doesn't mean you can't have several views - use iron-router for that.
But by design, Meteor serves a big fat unique JavaScript/HTML/CSS application down to the browser, though there's a feature request to allow incremental loading. It is then up to the application (or more precisely, the JavaScript framework), to dynamically render its views in order to display different "pages".
I was wondering the same thing and it took me way too much time getting something started. I finally got a paged app working solidly by using Backbone views and routes, so I created a simple boilerplate project to make setting up an app like this easier in the future.
Live demo here: backbone-boilerplate.meteor.com
Source code here: github.com/justinmc/meteor-backbone-boilerplate
Have you looked at madewith.meteor.com?
A bunch of apps there have multiple views using Backbone also Jonathan Kingston who created britto has started simple meteor framework called Stellar
At this stage of the game not sure if there really are best practices. But these two seem to be the current flow.
You can also make a tabbed interface for multiple views. There is a package project "Smart package for generating a tabbed interface with pushState" github project here: https://github.com/possibilities/meteor-tabs
The best solution right now is using a routing package (router is basic but works). The workflow is something like this:
declare routes; return a template name for each route
place the reactive helper provided by the package in your body tag
the reactive helper will return the template associated to that route
you create a template for each route and optionally set custom publish functions
Router will give you browser history (client side).
Note that at this time there are some limitation on the way Meteor handles html/js. They are load all at the same time. The bright side is that once the app is loaded, page transitions will be instant.
I recently created a website for a friend (asp.net/sql server), the website includes news of his company and he and his team update this frequently.
The question has been asked if i could now create a widget / api of some sort that visitors of the website could now include the news on there own website should they wish too. I feel this needs to be a one line of code intergration or something that is extremely easy to intergrate.
Any recommendations or articles are welcome.
EDIT: how is something like this created

With jQuery's ajax and an asp.net handler that returns an injectable html chunk is my off hand guess at simple way. Other's will probably know of frameworks if you don't want to roll your own. Is RSS to primitive?
you could also write a REST service in WCF since you're using asp.net and have it return XML or JSON, depending on how you write your widget.
How something like that is created... Well, I've created a number of these and the process is fairly simple. Sorry I don't have an article to reference. Create a 'widget creation/builder' page with input parameters, when submitted either store those in the database and return an ID to associate with those settings, or generate a list of param's for those settings, or both. Simply output the <script> tag into a textbox. Like so (inside an AJAX callback):
$("#results").html("<script type='text/javascript' src='" + widget_path + params + "'></script>");
Where widget_path is the absolute path to the widget ASP script, and params is either something like key=454 or theme=sunny&source=34&count=50 etc. Either manually or using something like jQuery.param to serialize the form. An alternative would be two <script> tags with settings in the 2nd and calling a widget initialize function.
They can copy and paste that into their site, and that ASP script should output only JavaScript, which you can either document.write() or use a JS library (such as jQuery) to operate on the DOM (.click() etc). If using a database the ASP script would check the key param and grab the widget settings, if not then simply process the params. It's important to mention if you want to communicate back and forth with an API, you need cross-domain enabled or you could simply use JSON (in ASP script check for a 'callback' parameter, wrap JSON in that function name, and use jQuery.getJSON with &callback=? at the end); there are other methods of course.
If you use a database, make sure to take security into account (SQL injection, etc.)
WidgetBox looks like a good, mainline method as well.
(I've posted this on the drupal forum too btw)
I'm converting the company websites to use Drupal, or at least trying to check that its going to be the best way forward. I have a background in PHP development, and I'm currently using the CakePHP framwork. I've built this site (not my design) and I can see how to replicate most of the functionality using Drupal, most likely using the CCK module.

As you can see from the homepage:
A user chooses a country.
The country is passed using an ajax call to a script that decides which phone is best based on 'in country' network coverage.
A div is shown recommending the visitor the best phone for that country.
I'm wondering how to go about this in Drupal, I'm definitely not after a step by step guide, I just want to know if this kind of thing is possible with Drupal, and what approach to use.
If someone can help that would be superb. Thanks.
Okay, so you've got a path you're defining in hook_menu, which is where your form is being presented - or else you've got it set up as a webform in a node, that could work too.
Either way, in your form you're going to be using AHAH - check out http://api.drupal.org/api/drupal/developer--topics--forms_api_reference.html/6#ahah and http://drupal.org/node/348475 .
Basically, you're going to define another path in hook_menu that's of type MENU_CALLBACK, and which will receive the country as input, and then will return the div that you'll display on the screen.
One core example of AHAH that may be useful to you is where you're entering a password and it lets you know if the password is secure enough - check that out.
Edit: There's also some good examples at http://drupal.org/project/examples.
I would look into using CCK and views. you can set up filters for the views. If filters don't work, you have the ability to include php code. I have also successfully added jquery code in the header of a view through which I was then able to have my view filtered by what is typed in a text box.
Coming from CakePHP using Drupal is a pain in the a** - even more for developers.
It's application structure might be designed to ease extensibility but this only means you have a system to enable your own plugins and themes.
While modules are basically the M+C-part the themes are the V-part of an MVC-application. The problem is that this seperation is not very strict in Drupal - in fact you have to break it sometimes in order to make things work (e.g. you have to include a theme_mymodule_myfunction() into your module as default output which you then can override with your theme using mytheme_mymodule_myfunction() ) And don't even bother looking for classes ( see http://drupal.org/node/547518 ).
Also there is no real link from a module to a theme. On many occations this is a good thing as you can switch modules and themes seperatly without creating a problem. For application builders coming from CakePHP (or any other framework) you often feel a lack of "wholesomeness" - you create parts for a base software and have to live with it's drawbacks.
IMHO I wouldn't recommend this step. Drupal is fine if you have to manage a website and might add a few modules to add neccessary value (image gallery etc.) but I definetly don't recommend it as a base for a customized web-app.
