tamaki.mes.utils.datasetsToZip

Description

Zips multiple datasets into a single ZIP archive returned as a byte array. Each dataset is written as a CSV entry whose file name comes from the corresponding element of fileNames. The two lists are paired by position, so fileNames and datasets should be the same length.

Syntax

tamaki.mes.utils.datasetsToZip(fileNames, datasets)

Parameters

Parameter	Type	Nullable	Description
fileNames	List	False	A list of file names (Strings), one per dataset (for example "locations.csv").
datasets	List	False	A list of Datasets to write as CSV entries, paired with fileNames by position.

Returns

A byte[] containing the ZIP archive.

Code Examples

# Zip a set of result datasets and download them (from the backup-compare results view)
results = self.view.custom.resultDatasets
fileNames = [str(name) + ".csv" for name in results]
datasets = [dataset for name, dataset in results.items()]
byteArray = tamaki.mes.utils.datasetsToZip(fileNames, datasets)
date = system.date.format(system.date.now())
system.perspective.download(filename="Backup-Compare-Results-{}.zip".format(date), data=byteArray)
