Adobe Exam AD0-E720 Topic 7 Question 26 Discussion

To access a view model within an existing block, the developer can use either of the following ways:

$block->getData('view_model'): This method will return the view model object that is assigned to the argument name ''view_model'' in the layout XML file. For example:

<referenceBlock name=''blog_posts_list''> ExampleObjectModel/ExampleObjectModel </referenceBlock>

In the template file, the developer can access the view model object by using:

$block->getData('view_model')

$block->getData('viewModel'): This method will return the view model object that is assigned to the argument name ''viewModel'' in the layout XML file. For example:

<referenceBlock name=''blog_posts_list''> ExampleObjectModel/ExampleObjectModel </referenceBlock>

In the template file, the developer can access the view model object by using:

$block->getData('viewModel')

The following methods are not valid and will not work:

$block->viewModel(): This method does not exist and will cause an error.

$block->getViewHodel(): This method is misspelled and will cause an error.
