README

A custom Laravel package for dynamic filtering of models, built to simplify the process of filtering data in Laravel applications.

Installation

1. Install via Composer

   Run the following command to add the package to your Laravel project:

   composer require janakkapadia/filterable

2. Usage

   This package provides a command to generate filter models dynamically.

   Creating a New Filter Model:

   php artisan filter:model {ModelName}

3. Add Filter Trait to Your Model

   use JanakKapadia\Filterable\Traits\Filter;
   
   class YourModel extends Model
   {
       use Filter;
   
       // Additional model code...
   }

4. Usage In Controller

   Basic filtering:

   public function index(Request $request)
   {
       $data = YourModel::filter()->get();
   }

   With parentheses wrapping where conditions:

   public function index(Request $request)
   {
       $data = YourModel::filter(true)->get();
   }

5. Request Example

   To filter and sort the data, you can make a request like this:

   GET URL/your-model?sort_by=id&search=title&status=active
   

6. Example Usage For Model Filter File

   In your filter model (YourModelFilter.php), you can define both filter and sort methods:

   class YourModelFilters extends Filter
   {
       // Define your filterable fields
       protected array $filters = ['search', 'status'];
       
       // Define your sortable fields
       protected array $sort = ['sort_by'];
   
       // Sort method
       public function sort_by($column): void
       {
           $this->builder->orderBy($column);
       }
   
       // Filter methods
       public function search($keyword): void
       {
           $this->builder->where(function ($query) use ($keyword) {
               $query->where('field1', 'like', "%$keyword%")
                   ->orWhere('field2', 'like', "%$keyword%");
           });
       }
   
       public function status($status): void
       {
           $this->builder->where('status', $status);
       }
   }

7. Query Examples

   Without parentheses (filter()):

   SELECT * FROM your_models 
   WHERE field1 LIKE '%keyword%' 
   OR field2 LIKE '%keyword%' 
   AND status = 'active'
   ORDER BY id DESC

   With parentheses (filter(true)):

   SELECT * FROM your_models 
   WHERE (field1 LIKE '%keyword%' OR field2 LIKE '%keyword%')
   AND (status = 'active')
   ORDER BY id DESC

   The parentheses version ensures proper grouping of conditions and can prevent unexpected results when combining multiple filters.

8. Advanced Features

   • Parentheses Wrapping: Use filter(true) to wrap where conditions in parentheses for complex queries
   • Filter Chaining: You can chain multiple filter operations together
   • Separate Filter and Sort Fields: Define filterable fields in $filters array and sortable fields in $sort array
