SpineInterface.jl

A package to interact with Spine databases from a Julia session.

Compatibility

This package requires Julia 1.6 or later.

Installation

You can install SpineInterface from the SpineJuliaRegistry as follows:

using Pkg
pkg"registry add https://github.com/Spine-tools/SpineJuliaRegistry"
pkg"add SpineInterface"

However, for keeping up with the latest developments, it is highly recommended to install directly from the source. This can be done by downloading the repository on your computer, and then installing the module locally with

using Pkg
Pkg.develop("<PATH_TO_SPINEINTERFACE>")

where <PATH_TO_SPINEINTERFACE> is the path to the root folder of the SpineInterface repository on your computer (the one containing the Project.toml file).

SpineInterface has been primarily designed to work through Spine Toolbox, and shouldn't require specific setup when being called from Spine Toolbox workflows.

When running SpineInterface outside Spine Toolbox (e.g. from a Julia script directly), however, SpineInterface relies on the Spine Database API Python package, which is accessed using the PyCall.jl module. Thus, one needs to configure PyCall.jl to use a Python executable with Spine Database API installed, which can be done according to the PyCall readme. If you're using Conda environments for Python, the .configure_pycall_in_conda.jl script can be used to automatically configure PyCall to use the Python executable of that Conda environment.

Trouble shooting

When the Julia runs under an active Conda environment, updating the Julia environment raises an error. Make sure to deactivate the Conda environment before updating the Julia environment. The error is subject to be fixed.

Upgrading

SpineInterface may be updated from time to time. To get the most recent version, just:

1. Start the Julia REPL (can be done also in the Julia console of Spine Toolbox).

2. Copy/paste the following text into the julia prompt:

   using Pkg
   Pkg.update("SpineInterface")

NOTE. It seems that Pkg.update does not always guarantee the latest version. Pkg.rm("SpineInterface") followed by Pkg.add("SpineInterface") may help.

If you have installed SpineInterface from source locally on your machine, you can update it simply by pulling the latest master from the repository.

Usage

Essentially, SpineInterface works just like any Julia module

using SpineInterface

url = "sqlite:///quick_start.sqlite"
commitmessage = "initial commit"

import_data(url,commitmessage;
	object_classes=["colors", "shapes"],
	objects = [
		["colors", "red"], 
		["colors", "blue"], 
		["shapes", "square"], 
		["shapes", "circle"]
	]
)

using_spinedb(url)

colors()#returns all colors
shapes("square")#returns the square

with import_data and using_spinedb being the key functions for interfacing a Spine Datastore. import_data is used to create a new Spine Datastore or write data to an existing Spine Datastore. using_spinedb creates the convenience functions to access the data in the Spine Datastore.
