The `dump` filter has what help for understanding complex data structures in AnQiCMS template development?
During the template development process of AnQi CMS, we often need to deal with various data passed from the backend.AnQiCMS is a powerful content model with flexible tag system, which allows us to easily obtain articles, categories, pages, and even custom fields of data.However, when the data structure becomes complex, or when we are unsure of what content a variable contains, the efficiency of development debugging will be greatly reduced.At this moment, the `dump` filter acts like a powerful 'data perspective mirror', which can help us clearly understand these complex data structures
