Object Manager argument replacement using nested array in custom module of Magento2

Question

Alan has written a great tutorial object manager argument replacement through di.xml . Everything works fine for me except nested arrays:

<type name="Pulsestorm\TutorialObjectManagerArguments\Model\Example">
 <arguments>
 <argument name="thearray" xsi:type="array">
 <item name="baz" xsi:type="string">
 <item name="0" xsi:type="string">one</item>
 <item name="1" xsi:type="string">two</item>
 </item>
 </argument>
 </arguments>
</type>

After using above di.xml configuration and running php bin/magento ps:tutorial-object-manager-arguments it says

There are no commands defined in the "ps" namespace

I'm missing something or the process of nesting arrays is changed now ?

Answer 1

Seems this error related to bin/magento utility. It tries to find command "tutorial-object-manager-arguments" in "ps". It is possible, that you have not installed a module or something went wrong with the module.

UPD. baz cannot be a string, it should be an array

<type name="Pulsestorm\TutorialObjectManagerArguments\Model\Example">
 <arguments>
 <argument name="thearray" xsi:type="array">
 <item name="baz" xsi:type="array">
 <item name="0" xsi:type="string">one</item>
 <item name="1" xsi:type="string">two</item>
 </item>
 </argument>
 </arguments>
</type>

• amitshree: This module is installed and working except my above configuration. After making baz to an array type, it shows other values but with error [ErrorException] Array to string conversion
• Arkadii Chyzhov: maybe cause the code waits, that $thearray should contain elements that can be converted to a string. look at Command class
