Email template with block

[galan83]

Hi everybody:

I'm developing a new module, and I'm stuck trying to insert a block in my email template. I need to loop over a product list array in that template. Because there is no way to loop there I've trying to do it using a block.

I have tried to call the block in this way:

{{block class="Magento\\Framework\\View\\Element\\Template" type="core/template" area="frontend" template="Slx_Lowstocknotifier::email/low_stock_product_table.phtml" }}

 Where Slx_Lowstocknotifier is my module name. And low_stock_product_table.phtml is inside my module folder in view/frontend/templates/email/low_stock_product_table.phtml

When magento is trying to compose the email, it fails getting this trace in system.log:

[2016-03-11 10:54:34] main.CRITICAL: Invalid template file: 'Slx_Lowstocknotifier::email/low_stock_product_table.phtml' in module: '' block's name: 'magento\framework\view\element\template_0' [] []

Any ideas? Is there other way to insert a block there?

Thanks in advance.

In which situations do you send the email?

Hi,

At the moment I'm sending it from a console command. If I don't use the block the email is sent correctly.

Thanks again.

[Dmitry_Fedyuk]

Maybe your console command use another area, not frontend?
Try to remove the area="frontend" declaration and move the template from the frontend folder to the base folder.

Hi again:

I have been trying your solution but it di not resolve the problem. I made a trace in  

Magento\Framework\View\Element\Template.php

And looking in:

protected function _toHtml()
{
    if (!$this->getTemplate()) {
        return '';
    }
    return $this->fetchView($this->getTemplateFile());
}

 I can see the file is trying to fetch is correct, the path is correct.

Now I'm getting the following exception: 

[2016-03-14 08:59:38] main.CRITICAL: exception 'BadMethodCallException' with message 'Missing required argument $debugHintsPath of Magento\Developer\Model\TemplateEngine\Plugin\DebugHints.' in /proyectos/demo2-tienda/codigo/vendor/magento/framework/ObjectManager/Factory/Dynamic/Developer.php:45

I created a controller action with the same logic and it is working perfect, so I suppose it is something related to the templates and commands.  Furthermore I set the area in the command controller:

public function __construct(
    \Magento\Framework\App\State $state,
    \Magento\Framework\ObjectManagerInterface $objectManager,
    \Magento\Framework\Mail\Template\TransportBuilder $transportBuilder,
    \Magento\Framework\App\Config\ScopeConfigInterface $scopeConfig,
    \Magento\Store\Model\StoreManagerInterface $storeManager
)
{
    $this->objectManager = $objectManager;
    $this->transportBuilder = $transportBuilder;
    $this->scopeConfig = $scopeConfig;
    $this->storeManager = $storeManager;

    $state->setAreaCode('frontend'); 
    parent::__construct();
}

Thanks again.

Hi,

Did you manage to find a solution to your problem?

I have a very similar issue..

I have a command that fetch data from a warehouse management system and process orders.

I try to send an email with the tracking number but when I do I get the same error as you:

string(102) "Missing required argument $debugHintsPath of Magento\Developer\Model\TemplateEngine\Plugin\DebugHints."

I do set up my area code to frontend.

$this->state->setAreaCode('frontend');

But when I try to send the email I get the error above.

try {
    $this->orderSender->send($order_instance);
} catch (\Exception $e) {
    var_dump($e->getMessage());
    die();
}

I really don't understand why I get this error...

Hi AHeaven-1, I was struggling with the same issue, this seemed to work for me: 

$state->setAreaCode(\Magento\Framework\App\Area::AREA_GLOBAL);

If you don't plan on using the state class beyond the constructor I would not even bother assigning it to $this eg:

private $_transportBuilder;

    public function __construct(
        \Magento\Framework\Mail\Template\TransportBuilder $transportBuilder,
        \Magento\Framework\App\State $state
    ){

        $state->setAreaCode(\Magento\Framework\App\Area::AREA_GLOBAL);
        $this->_transportBuilder = $transportBuilder;
    }

Finally if you intend running this command as a cron job, using magento's cron feature may be a bit more eloquent than using the command line directly.

Hey AHeaven-1,

Have you been able to fix this issue? I tried Zengoma's fix, setting the area code to both global and frontend, but I am still getting the error. I set up a controller with the same code, and the email sends fine when I go to the route. However, when I call that controller in my cron job, it gives me the error once more.

Any help would be greatly appreciated.

What worked for me was the following:

$this->_objectManager->configure($this->_configLoader->load('adminhtml'));

This was occurring for me in a test script that I simply use for testing during development:

class TestApp
    extends \Magento\Framework\App\Http
    implements \Magento\Framework\AppInterface {
    /**
     * @param \Magento\Framework\ObjectManagerInterface $objectManager
     * @param Event\Manager $eventManager
     * @param AreaList $areaList
     * @param RequestHttp $request
     * @param ResponseHttp $response
     * @param ConfigLoaderInterface $configLoader
     * @param State $state
     * @param Filesystem $filesystem,
     * @param \Magento\Framework\Registry $registry
     */
    public function __construct(
        \Magento\Framework\ObjectManagerInterface $objectManager,
        Event\Manager $eventManager,
        AreaList $areaList,
        RequestHttp $request,
        ResponseHttp $response,
        ConfigLoaderInterface $configLoader,
        State $state,
        Filesystem $filesystem,
        \Magento\Framework\Registry $registry
    ) {
        parent::__construct($objectManager, $eventManager, $areaList, $request, $response, $configLoader, $state, $filesystem, $registry);

        $this->_state->setAreaCode('adminhtml');
        $this->_objectManager->configure($this->_configLoader->load('adminhtml'));
    }

Adding the $this->_objectManager->configure line solved the issue for me. It dictates that the di.xml directive set in vendor/magento/module-developer/etc/adminhtml/di.xml is loaded. For the frontend, the same would need to be done, replacing 'adminhtml' with 'frontend' (I think that would be it, haven't tested that)

[ElGatito]

The solution from @dunagan5887 is confirmed to be working.

In my case it was used for the frontend area.

Please find a working version command line class below:

<?php
namespace NameSpace\Module\Console\Command;

use Symfony\Component\Console\Command\Command;
use Symfony\Component\Console\Input\InputArgument;
use Magento\Framework\Exception\LocalizedException;
use Symfony\Component\Console\Input\InputInterface;
use Symfony\Component\Console\Output\OutputInterface;

class CustomCommandClass extends Command
{
    public function __construct(
        \Magento\Framework\App\State $state,
        \Magento\Framework\ObjectManagerInterface $objectManager,
        \Magento\Framework\ObjectManager\ConfigLoaderInterface $configLoader
    ) {
        $state->setAreaCode('frontend');
        $objectManager->configure($configLoader->load('frontend'));
        parent::__construct();
    }

    ...

}
