Common mistake that other can have when migrate to version 5.2 and that i have :-)
1. 'Form'=> Illuminate\Html\FormFacade::class,
'HTML'=> Illuminate\Html\HtmlFacade::class are no more supported by Laravel, otherwise you can see laravelcollective https://laravelcollective.com

2. In blade php, when using section, i had got the following error:
Cannot end a section without first starting one, => solution remove @stop or @endsection

3. In my blade template $errors not appearing=>solution :
Route::group(['middleware' => ['web']], function () {
    //add your routes here
    })
 $errors is now included in session by the middleware!.

 
4. Upgrading from 5.0 to 5.2 filters before and after are no more supported and replaced by middleware!! great new functionality!    
    
5. From version under 5: the hardest work is too migrate the blade to the new directive  {!! !!}.

6. Other things
In ajax called don't forget to put the token csrf_token() in L5.2 or in your form if you don't use HTML:Form

7. How to pass parameters between middleware?

for example i've got a middleware that checks rules of users , second middleware loads contents that users can access, the only way i found is to set the user's rules into the session and that second middleware can pull.

It is just some little things, the upgrade guide  https://laravel.com/docs/5.2/upgrade is very well documented!

about files management?
all systems have got their own systems, specially in cms,
How do i handle it simple in groovel who implements some of few cms features?
I decide to insert in a table all files that are downloaded in groovel in order to controll what users do

I limit the size of number files that a user can upload

Each time a content is deleted all files are deleted, perhaps it is better to make asynchronously this method for
huge volume but with several of hundred users it is enough don't complex it.But it is not so hard to do it

Now in groovel we support powerpoint, excel, doc,pdf, png,jpg

Easy to think that you will attach to your content several files!A good way to share documents!
Let's try it!!

A ready starter application to understand how groovel works with its template engine :Blade

In the installation of groovel , you've got a ready simple blog that you can customize and play with
the blade engine template.This is the common template engine working with laravel and optimizing to make template reusable

When you install groovel, all template layout blog (.blade) are copied from starter-templates, and then published in resources/views directory, assets are published in the public directory
All data are available via session data. In the main template blog.blade file, we see the variable
{{content}} this is the data that groovel loads when you access to the blog page
In fact if we follow the workflow a middleware ( like nodejs) intercepts the request , and determines with the url you access,the controller to call that will init the session context.

The workflow is :

blogs->called Groovel\Cmsgroovel\Http\Middlewares\ContentsBeforeMiddleware.php class :
$contents=$controllerContents->callAction('loadContents',array('extension'=>$site_extension,'lang'=>$lang,'layout'=>$params['type']));
\Session::put('contents',$contents); we say to groovel to call the loadContents method to load the contents, depending of the layout and on the language.

If we focus on the template .blade
The syntax is simple :
loops @foreach , conditional :@if
inheritance is possible

@extends inheritance the base template
and override the section content @section in the base template
@foreach ($contents as $content) , loop all the contents from the session
and more inside the laravel box ,there is a feature to paginate the content :{!! $contents->render() !!}

An extract of the file blog.blade.php :

@extends('blog.base.core')
@section('content')

@if($contents!=null)
  @foreach ($contents as $content)
   @if($content['contentType']=='blog')
    @if($content['uri']==null)
      {!!$content['title']!!}
    @else
      {!!$content['title']!!}
   @endif
       by {!!$content['author']!!}Posted on {!!$content['created_at']!!}

    @endif
   @endforeach
@endif
{!! $contents->render() !!}
@stop

Why i decide to use blade? because i wanted to stay in the same technical domain than to propose to use angularjs or vuejs in order to limit the complexity but it is possible to propose api services that interoperate with these frameworks.

In a next post i will explain how do i expose API that you can use in ionic framework ;)

How to secure access and share privileges to other users and make it collaborative platform?

Lot of systems multiply complexity authorizations, multiply profiles access to specific rights, inheritance,
configuration , rules hard coded , and it's become after difficult to maintain when time past.
How and which strategy do i choose in groovel?
I wanted something that is not intrusive in the code and quickly configured via a web interface,easy to find when a right access missing.

The idea to use profile is quite good,i don't want to rebuild the wheel, so i just decided to add rights access depending on the URL you try to access.
In each url ,i know what actions should be processing : CREATE READ UPDATE DELETE,
So i make the mapping between a profile of users that contains URL and actions which he can execute: is it CREATE,READ,UPDATE,DELETE?
After i make the matching with the privilege access that you have to do for the actions.

Here, you see how groovel configure a profile  for users:

In each url resources , there is an action which is mapped.

When you call an uri you see in log files (example) :

PARAMS ACCESSURL  
[2016-11-18 06:39:54] local.DEBUG: array (
  'uri' => '/', //the url you try to go
  'method' => '',
  'controller' => '',
  'view' => 'cmsgroovel.pages.firstinstall.welcome', // you try to access to this page
  'action' => 'op_none', //no specific actions you have to have
  'type' => 'blog',
)  
At this moment groovel loads your profile and check if it matches with uri, action

When you miss a privilege , it is easy to go and see in the logs file:
find this line  : middleware UserRules NOT AUTHORIZED : END METHOD handle()
it indicates after the url and the action that you don't have

Add it after!

The strong design in groovel is that the authentification and the check rules access is mutualized and centralized.

You can duplicate the profiles and add to specific users.

ADMIN profile : you are the master of all systems

PUBLIC profile : you can just access to your messages, very basics thing.

CLIENT profile : you can interact by publishing contents! as a blog ccontributor.

What do you think?

Thanks for the reading !

One mistake that makes software is to complicate the way to develop new modules.
In groovel, I make choice to use a framework : Laravel that enables the way to develop new components easily
How do you process it in Groovel?

For example i create a new package to handle payment paypal,First we create a new folder called (for example packages) like this :

We Create our service provider that will be handled and registrated in Laravel : more expertise in Laravel info :
https://laravel.com/docs/5.2/providers#writing-service-providers , if you ve got some problems ask me ;)

In config directory, in the file app.php declare your provider

In composer.json file declare your path to your package :
"Groovel\\Paypal\\": "packages/groovel/paypal/src/"

Finally launch the command composer dump-autoload , this command will do all for you, manage dependencies, and registrate classes in your application

In directory vendor/composer look at the file autoload_psr4.php you will see your binding, all your classes will be loaded in your path.

That's all!

When your package is ready to publish i will explain in next blog post how to share it for everybody ! in packagist :-)
https://packagist.org/

In this new article i will show you a new easy feature in groovel
The common use case when you generate some contents for example you create some products in order to create your shop
you will have the problem to sort them in group of common type if you want that your user can be easily find what he wants.
It is optimization search.
Lot of software products are using some other outside frameworks, in my opinion and philosophy of groovel i propose you something simple but
efficient for you in order to limit the complexity.
I implement a simple tagging engine search:
How do you process it?
1. design your content type for example a search jobs engine
for this content type i want to groups by technologies qualification for example knowledge language : Java C# ..
The name of group is a category:
2. Go to create a category :

3. Go create a tag : the key word that is in a category

  4. And when you will create a new job post you will have to choose your tag :

Great now when you will set your search engine you will look for jobs by tag words.

If there is a lot of contents several ways to optimize the speed search such ...indexation database contents ...

First blog post ,this is a nice demo of how groovelcms works!

Any fix, bugs, questions, write us!
