Eloquent 
Eloquent Helper Code Generation 
Eloquent is full of magic, so PhpStorm needs some helper code to understand it. There are 2 ways to do it:
- barryvdh/laravel-ide-helper package can generate the needed phpDocs(ide-helper:modelsartisan command)
- use our own Eloquent Helper code generation - it generates more powerful helper code.
Generate Eloquent Helper Code command is available in the Laravel main menu item.
INFO
It also can be called by quick key combination: Shift-Cmd(Ctrl)-.
 Helper code will be generated without any dialog windows.
INFO
First call will ask you to configure the Eloquent helper code generation. 
 Later you can change those parameters at any time. 
 There is Helper Code Parameters... in the Laravel main menu item.


Fetch data from 
Tables and columns can be fetched from migrations or existing database connection.
INFO
It's available to choose the both fetch types: from database and from migrations with the Also fetch migrations checkbox. 
 Migrations are fetching after connection and the fetched data from migrations will be added to the generated helper code as an addition. 
 It doesn't replace or remove anything.
Create collection proxy helper classes 
Adds a helper code for supporting Collection proxies for all Eloquent models.
Create collection proxy helper classes 
Adds a helper code for supporting Collection proxies for all Eloquent models.
Add "*_count" properties for "*Many" relations 
Eloquent adds _count properties for entities fetched by withCount method, and you can add these properties to the helper code: User::withCount('posts')->first()->posts_count
Remove phpDocs from model classes 
The last option will remove all phpDocs from models. 
 Clear ide-helper phpDocs, for example.
Completions 
After generating a helper code, Laravel Idea starts to complete fields and relations almost everywhere:

Even in complex cases, it understands that here it should complete Post class fields:

Relations chain is also not a problem:

Fields inside class:

Code generations 
JSON resource generation is accessible from the main Code generation menu or in the Generate context menu: (Cmd-N, Alt-Insert) in the Eloquent class. It uses fields and relations information to generate full JSON resource for this class:

Database factory generation is accessible from the main Code generation menu or in the Generate context menu: (Cmd-N, Alt-Insert) in the Eloquent class. It uses fields and relations information to generate full database factory for this class:

Database factory type hinting 
Laravel Idea hints the type of factory()->create() calls:

Multiple create also supported:

Productivity Tips 
Autocomplete $fillable property 
Laravel Idea provides a quick way to complete $fillable property of Eloquent models automatically.
Run Generate command(Cmd-N, Alt-Insert) inside $fillable property array and choose Add All Fields: 
WARNING
This works only if Eloquent Helper code was generated before.
