    <p>Is it possible to create variables or even shared objects (like DB adapter) at in Module.php for use in all view controllers? (Zend Framework 2)</p> <p>For example:</p> <pre><code>class Module { public function onBootstrap(MvcEvent $e) { $moduleConfig = $e-&gt;getServiceManager()-&gt;get('Config') } } </code></pre> <p>And in a controller, somehow access using:</p> <pre><code>$this-&gt;moduleConfig['db'] </code></pre> <p>In above I know that would just be the config array for the db adapter, but how would that even work?</p> <p>I see that one can do this in a controller action:</p> <pre><code>$config = $this-&gt;getServiceLocator()-&gt;get('Config') $dba = new DbAdapter($config['db']); </code></pre> <p>I don't want to do that every place I need my config. How could I make it something like: $this->config ?? So its available to all actions. Even better, how to do that in the entire Module? I know I am going about this all wrong, but in ZF1 we had Zend_Registry::get() for simple things like this. I am reading over the docs and all sorts of tuts out there, but always there's some assumptions being made and I just get lost. So all I really want is : A) A Globally accessible config item, B) A globally accessible db adapter</p> <p>I just want to call on $this->db or $this->config->item in my controllers. Is this possible? I know I am missing something totally simple.</p> <p>Also I did try setting $this->config in my __construct using $this->getServiceLocator()->get('Config'); But I understand that service locator is not available yet during construct. I tried doing similar by setting up a preDispatch in the onBootstrap of the module, but I can't seem to get those items into my controllers.</p> <p>FYI, I do have this in my global.php (and no, its not staying there, just example):</p> <pre><code>'db' =&gt; array( 'driver' =&gt; 'Pdo', 'dsn' =&gt; 'mysql:dbname=mydb;host=localhost;', 'username' =&gt; 'root', 'password' =&gt; '', 'driver_options' =&gt; array( PDO::MYSQL_ATTR_INIT_COMMAND =&gt; 'SET NAMES \'UTF8\'' ), ), </code></pre> <p>I am able to access that and other items in any action using getServiceLocator(). I'd like those items to be available as my controller properties as in $this->config->item. </p> <p>I appreciate any guidance! Thanks!</p>

    2. COYeah, I was just figuring that out last night. Got the db adapter and config shared globally plus a predispatch method setup on controllers to add a db property of that object, kind of nice I have to admit. It's just way confusing at first and works so different from Zf1. I will post my solution later. One question I have still. What about adding global variables in service manager? Would that be an invokable with just a value like a string or boolean or int? I will try it.

    3. COZF2 is to ZF1 like ZF1 to Symfony or the framework of your choice. Just a different framework completely. I'm not sure what you'd like to do with global variables. Either something is available from the config, session related or shouldn't be a global maybe?

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
