Custom KanbanService

[a.slyzhko]

Is it possible to create custom KanbanService to be used instead of standard one? I tried to create new class in custom/Espo/Custom/Tools dir, but it has no affect.

Take a look at Dependency Injection. I haven't tested it, but you could give this a try to see if it works. Make sure the namespaces are correct.

custom/Espo/Custom/Binding.php

<?php
namespace Espo\Custom;

use Espo\Core\Binding\Binder;
use Espo\Core\Binding\BindingProcessor;

class Binding implements BindingProcessor
{
    public function process(Binder $binder): void
    {
        $binder
            ->bindService('Espo\\Tools\\Kanban\\KanbanService $service', 'customKanbanService');
    }
}​

custom/Espo/Custom/Resources/metadata/app/containerServices.json

{
    "customKanbanService": {
        "className": "Espo\\Custom\\Tools\\Kanban\\KanbanService"
    }
}
​

No need to define a container service.

$binder->bindInstance(\Espo\Tools\Kanban\KanbanService::class, \Espo\Custom\Tools\Kanban\CustomKanbanService::class);​ 

CustomKanbanService should extend KanbanService, as there's no interface.

As an alternative, you can define a new route for the same URI path that will call a custom API action.

What error did you get? I just tried to define a custom route for an existing route path and it worked.

I see. I'll try to address this problem in v8.2.

Hey yuri

What if we need to change a method on an existing class, e.g i want to change the method generate on this class Espo\Tools\Pdf\Service with my custom implementation in a custom service class Espo\Custom\Tools\Pdf\CustomService. would the binding class below work:

<?php
namespace Espo\Custom;

use Espo\Core\Binding\Binder;
use Espo\Core\Binding\BindingProcessor;

class Binding implements BindingProcessor
{
    public function process(Binder $binder): void
    {
       $binder
           ->bindInstance(\Espo\Tools\Pdf\Service::class, \Espo\Custom\Tools\Pdf\CustomService::class);​
    }
}​

Do i still have to extend the pdf Service on my custom Services and implement a generate function to overwrite the function on the pdf service class ?

Thanks

Hey Yuri,

when i tried this $binder->bindInstance(\Espo\Tools\Pdf\Service::class, \Espo\Custom\Tools\Pdf\CustomService::class);

It doesn't work. i get an error expected type object. when i checked the bindInstance it require an object as a second argument. Is there something i am missing. I am trying to bind the pdf service class with a custom pdf service class.

[a.slyzhko]

You need to instantiate your custom service and pass it as a second param, instead of using its name. ::class returns a string representing a name of the class, not an object of this class

i have tried that it didn't work either. But i figure it out instead of bindingInstance i have used an implemtation extending original class to my custom class and now it works like a charm.
