What I want to do:
Have an html form, with a file input inside. When a file is chosen, the file input should upload the file, and get a file id, so when the form is submitted, the file id is posted with the form and written in the database. 

Shorter version: **I want to store meta data (id for example) with my files.**

Sounds simple, yet I struggle to do that in LoopBack. 

There has been a couple conversations ( [1][1], [2][2] ) about this topic, and neither seemed to lead to a solution, so I thought this might be a good place to find one once and for all.

The simplest solution would be to use model relations, but LoopBack doesn&#39;t support relations with the file storage service. Bump. So we have to go with a  persistedmodel named `File` for example, and override default create, delete so it saves and deletes from the file store model I have - named `Storage`.

My setup so far:

 - I have a model /api/Storage which is connected to a [loopback storage service][3] and is saving file successfully to the local filesystem. 
 - I have a PersistedModel connected to Mongo with file meta data: `name`,`size`, `url` and `objectId`
 - I have a remote hook set up before`create` so the file can be saved first and then it&#39;s `url` can be injected into `File.create()`

I&#39;m there, and according to [this LoopBack page][4], I have the ctx which should have the file inside:

    File.beforeRemote(&#39;create&#39;, function(ctx, affectedModelInstance, next) {})`

What&#39;s `ctx`? 

&gt; `ctx.req`: Express Request object.  
&gt; `ctx.result`: Express Response object.

Ok, so now I&#39;m at the Express page, pretty lost, and it sais something about a &#39;body-parsing middleware&#39; which I have no idea what it might be.

I feel like I&#39;m close to the solution, **any help would be appreciated**. Is this approach right?
