folktales
folktales
enables the creation, access and modification of SQL databases, with an emphasis on storing dictionaries easily and accessing database tables as pandas DataFrames easily. It also provides template dictionaries suitable for logging. While it can be used with other databases, it is designed currently to be used easily with SQLite3 databases.
folktales
might be used in a logging context, whereby a status dictionary, which features a UUID4 identifier and a UTC datetime by default, is updated with program characteristics or other data and then saved to database.
setup
sudo apt install sqlite
pip install folktales
Sqliteman
is a GUI tool that can be used to interact with SQLite3 databases.
apt install sqliteman
examples
create a database
folktales.create_database(filepath = "database.db")
access a database
database = folktales.access_database(filepath = "database.db")
insert a dictionary into a database table
folktales.insert_dictionary_into_database_table(
dictionary = {
"a": 1,
"b": 2
},
table_name = "data",
filepath = "database.db"
)
state dictionaries
A template state dictionary can be created in the following way:
folktales.template_state_dictionary()
This returns a dictionary that features a UUID4 identifier (uuid.uuid4()
) and a UTC datetime (datetime.datetime.utcnow()
).
A state dictionary can be created at the same time as updating it with an existing dictionary in the following way:
folktales.state_dictionary(
entries = {
"state_ID" : "84f80687-cdd7-48f9-b21c-3d75fd759604",
"price_recommendation" : 5007.24
}
)
insert a state dictionary into a database table
folktales.insert_state_dictionary_into_database_table(
entries = {
"state_ID" : "84f80687-cdd7-48f9-b21c-3d75fd759604",
"price_recommendation" : 5007.24
},
table_name = "do_stocks",
filepath = "database.db"
)
access a database table as a pandas DataFrame
df = folktales.DataFrame_of_database_table(
filepath = "database.db",
table_name = "do_stocks"
)
