Midas Store

Description

This package contains a midas module providing a database simulator. This works like most other collectors for mosaik, i.e., it accepts any number of inputs and stores them in a database file.

Although this package is intended to be used with midas, you can use in any mosaik simulation scenario.

Version: 2.1

Installation

This package will usually installed automatically together with midas-mosaik if you opt-in any of the extras, e.g., base or bh. It is available on pypi, so you can install it manually with

pip install midas-store

Usage

The complete documentation is available at https://midas-mosaik.gitlab.io/midas.

Inside of midas

To use the store inside of midas, just add store to your modules

my_scenario:
  modules:
    - store
    - ...

and configure it with (filename is required, everything else is optional and can be left out if the default values, shown below, are used):

  store_params:
    filename: my_results.csv
    step_size: 900
    unique_filename: False
    keep_old_files: False

All simulators that have something to store will then automatically connect to the store simulator.

Any mosaik scenario

If you don't use midas, you can add the store manually to your mosaik scenario file. First, the entry in the sim_config:

sim_config = {
    "MidasCSV": {"python": "midas_store.simulator:MidasCSVStore"},
    # ...
}

Next, you need to start the simulator (assuming a step_size of 900):

store_sim = world.start("MidasCSVStore", step_size=900)

Finally, the model needs to be started:

store = store_sim.Database(filename="my_results.csv", keep_old_files=False, unique_filename=False)

Afterwards, you can define world.connect(other_entity, store, attrs) as you like.
