Laravel whereExists table name?

Question

Laravel

Post::whereExists(function($query) use() {
    $query->select('*')->from('entity_tag')->where('entity_tag.entity_id', 'posts.entity_id'));
});

This is the code that returns

SELECT * FROM pr_posts WHERE EXISTS(
    SELECT * FROM pr_entity_tag WHERE pr_entity_tag.entity_id = posts.entity_id
)

Why doesn't it convert posts to table name?

Answer 1

Because no one promised that he would do it. The second argument is the comparison value, how does the framework know that you will pass the name of the table and column there? Such rare cases - by hand.
