fix: the error in obtaining the document list

The code is mostly clean, but there are some minor improvements that can be made:

1. In the get_query_set method, you may want to ensure that the dynamic model retrieved by get_dynamics_model has all the fields specified ('char_length', 'paragraph_count', "update_time", 'create_time') defined and accessible.

2. When returning the results, instead of using a dictionary with keys 'document_custom_sql' and 'order_by_query', it might make more sense to directly define these variables within the function scope for clarity:

def get_query_set(self):
        # existing logic...

        return query_set, order_by_query_set

3. If possible, consider moving away from using hardcoded field names like 'status'. You could set them up dynamically based on configuration settings so they're easier to change later without modifying many places in your codebase.

These changes won't significantly impact functionality but will improve readability and maintainability slightly.
