"""Models are used for saving and loading in-game objects.
How you use models:
Saving: The first thing you need to do is specify a table name. This tells
the database where to put all of the data for this kind of class. Use the
statement "db_table_name = <my_model>". Table names MUST be unique to all
other model table names, or else bad things will happen.
Next, models save data using columns (defined above). Any class attribute
you want to save needs to have its own column. The name given to the column
will be the name of the attribute when the class is initialized (loaded). If the
attribute is anything more complex than a string, you will need to override
the read and write functions (some basic ones in shiny_types; you can also
write your own). Add the columns to the db list and your objects will save!
Example:
db_table_name = "sack_of_gold"
db_columns.append(
Column("owner", primary_key=true),
Column("ammount", type="INTEGER", default=20, read=read_int),
Column("weight", type="INTEGER", read=read_int)
)
NOTE: Many values such as 'read' and 'write' are left out above. You can do
this for anything except for the column name, and it will default to the
values shown in the Column class.
Loading: Dependent models in shinymud load in a parent-child system. That is,
an area loads all of its rooms, a room loads all of its npcs, an npc loads its
inventory. When a parent model loads a dependent model, it hands the child a
huge lump of raw slq data, which the child parses through models.
To activate a models super powers of parsing, simply add this line to the init
function of your class:
Model.__init__(self, args)
Where 'args' is a dictionary from the parent.
