Database Lists

Store a list-like object in the database

Storing lists in the context of databases can be challenging. The easiest way to overcome this is to restructure your project to use multiple models and link them together with ids. Though this method might still be a bit complex. So, to solve this problem Ask has built-in database models ready to go for storing a list (list-like) objects.

The built-in database model is called List and it can be used along with the database column data type list_id (which is just an alias for int, but it improves readability) to link it in a table.

Create a DB List

my_list = db.list([1, 2, 3, 4])  # The passed in list is optional.

This will automatically also add the row to the database.

Properties of the List Object

.list()

• Basically a serialization method.

• Returns a standard list.

• Note! Don't mutate the return value of this method, it won't update the list in the database.

Example:

my_list = db.list(['a', 'b', 'c'])
my_list.list()  # ['a', 'b', 'c']

.get()

.push()

.remove()

.set_list()
