How to store array in mysql database using django model?

Question

1.I have array of products and want to store it in mysql database using django model.I tried with 'ListTextField' in models.py as below,

products = ListTextField(
        base_field=models.CharField(max_length=255),
        size=100,  # Maximum of 100 products in list
)

and I am using serializer to save data.But it is not working.

2.If I want to save data manually from views.py.How should I pass array of products in model object.for example,

obj=ContactDeatils(name='abc',products=['aa','bb'])

This gives me 'invalid syntax error' near products.

please help.
