knp_paginator not working in symfony service

  • 772

I have defined a function in which I use the pager, used in my controllers it works correctly. However, when I define a service to not copy and paste the code, I have the following:

 app.paginacion:
    class: Caja\SiafcaInternetBundle\Services\Paginacion
    public: true
    arguments: ["@knp_paginator"]

In my config.yml

knp_paginator:
page_range: "%knp_paginator_page_range%"
default_options:
    page_name: "%knp_paginator_page_name%"
    sort_field_name: "%knp_paginator_sort_field_name%"
    sort_direction_name: "%knp_paginator_sort_direction_name%"
    distinct: "%knp_paginator_distinct%"
template:
    pagination: "%knp_paginator_pagination%"
    sortable: "%knp_paginator_sortable%"

And in my controller I define the following class

class Paginacion{

private $paginator;

public function __contruct($paginator){
   $this->$paginator = $paginator;
} 

public function obtenerPaginacion($request,$aportantesWS,$totalAportantes)
{
    if (!$aportantesWS) 
    {
        $pagination = null;
    } 
    else 
    {
        // $paginator = $this->get('app.knp_paginator');
        $pagination = 
                $this->paginator->paginate(
                                        $aportantesWS,
                                        $request->query->getInt('page', 1),
                                        20
                                    );
        $pagination->setTotalItemCount($totalAportantes);
    }
    return $pagination;
}}

For example calling it:

$this->get('app.paginacion')->obtenerPaginacion($request,$aportantesWS,$totalAportantes)

When I try to use it, it generates the following error Error: Call to a member function paginate() on null Checking with dump() the request data , contributorsWS and totalcontributors come back non-null, that is, with data.

    I found the solution. Following the following post on stackoverflow

    Modify my definition in services.yml 

    paginacion:
    class: Caja\SiafcaInternetBundle\Services\Paginacion
    public: true
    arguments: ["@knp_paginator"]
    calls:
    - [setPaginator, ["@knp_paginator"]]

    Enter the calls -[setPaginator, ["@knp_paginator"]]

    Modify my controller by adding the setPaginator method

    public function setPaginator($paginator)
{
    $this->paginator = $paginator;
}

    Staying as follows:

    class Paginacion{

private $paginator;

public function __contruct($paginator){
   $this->$paginator = $paginator;
}

public function setPaginator($paginator)
{
    $this->paginator = $paginator;
}

public function obtenerPaginacion($request,$aportantesWS,$totalAportantes)
{
    if (!$aportantesWS) 
    {
        $pagination = null;
    } 
    else 
    {
        $pagination = 
                $this->paginator->paginate(
                                        $aportantesWS,
                                        $request->query->getInt('page', 1),
                                        20
                                    );
        $pagination->setTotalItemCount($totalAportantes);
    }
    return $pagination;
}}
