Check the ./scripts/main.py for a full example.
# main.py
# ...
# Define the fields for the table and entities
datasource = DataSource()
table = JsonTable('users', os.path.join(path_root, 'scripts', 'data'), fields)
datasource.add_table(table)
datasource.clear('users')
dummy_users = [
User('John Doe', 'test@asd.com', 'johndoe'),
User('Jane Doe', 'test3@asd.com', 'janedoe'),
User('Mary Poppins', 'poppinst@industry.com', 'marypoppins'),
]
for user in dummy_users:
datasource.insert('users', user)
filters = [
Filter([
FilterCondition('name', 'Doe', FilterTypes.CONTAINS),
FilterCondition('email', 'test@asd.com', FilterTypes.EQUAL)
]),
Filter([
FilterCondition('name', 'Mary', FilterTypes.CONTAINS),
])
]
for user in datasource.get_by_filters('users', filters):
print(user)
print("Unique")
mary = datasource.get_unique('users', 'username', 'marypoppins')
print(mary)
