[Feature] File Upload Support

[devalade]

Description

Add support for file and image uploads in generated CRUDs.

Proposed Syntax

php artisan crudify:generate Product \
  --fields="name:string,photo:file,images:file:multiple,brochure:file:pdf"

Generated Components

• Migration: Add photo as string (path storage) or text (JSON array for multiple)
• Model: Handle file casts and accessors
• Livewire Create/Edit: Add <input type="file" wire:model="photo"> with @livewireScripts handling
• Index: Show thumbnail previews in table
• Show: Display full image or download link
• Factory: Use UploadedFile::fake()->image() for testing

Key Considerations

• Disk configuration (local/s3)
• Multiple file uploads
• File type validation in form requests
• Cleanup on delete/update

Example

// In Livewire Create component
#[Validate(['photo' => 'nullable|image|max:2048'])]
public $photo;

public function save(): void
{
    $validated = $this->validate();
    
    if ($this->photo) {
        $validated['photo'] = $this->photo->store('products', 'public');
    }
    
    Product::create($validated);
}
