    <p>I have a follow-up question to the one discussed here: <a href="https://stackoverflow.com/questions/15758936/laravel-core-method-confusion/17295616#17295616">Laravel core method confusion</a></p> <p>I am in the same situation as driechel (author of question above) has been before, currently getting used to Laravel 4 FW and examining the core. Although a precise answer has been given I still don't understand the logic and what is happening under the hood. So I would very much appreciate a further explanation. I know this might be a duplicate but since I cannot post comments yet I'll give it a shot with a new question. Hope it' ok this way.</p> <p>I have been looking at this from another angle starting at this article: <a href="http://blog.joynag.net/2013/05/facades-in-laravel-4-and-static-methods-resolution/" rel="nofollow noreferrer">http://blog.joynag.net/2013/05/facades-in-laravel-4-and-static-methods-resolution/</a></p> <p>When examining the call <code>File:get()</code> I finally end up at the <strong><em>Container class' share function</em></strong> which is called with this actual parameter <code>share(function() { return new Filesystem; }</code>.</p> <p>What I just can't figure out is the use of <code>$container</code>. Especially at the second occurence within the closure: </p> <p><code>$object = $closure($container);</code></p> <p>Could you please clarify this again? Why is <code>$container</code> passed as a parameter here and what is actually contained in it? As far as I understand <code>$closure</code> at that point holds and executes <code>function() { return new Filesystem; }</code> which has no input parameter.</p> <p>I am lost. Studied this and the PHP anonymous functions/closures now for two days straight and still can't figure it out. I neither understand the syntax of <code>$closure($container)</code> here nor the logic.</p>

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.
