Walkthrough

The update to DataSource.ts enhances the data source class by integrating template variable support. It imports necessary utilities for template handling and adds a method to apply these variables to query filters, ensuring dynamic and customizable queries. Additionally, the getAccountSummaries method has been updated, likely to accommodate the new template variable functionality.

Changes

File	Change Summary
src/DataSource.ts	Imported ScopedVars and getTemplateSrv, added applyTemplateVariables method, and updated getAccountSummaries method.

Poem

In the code where logic hops around, 🐇💻
A change was made without a sound.
Variables template, now they weave,
Through queries' fabric, they interleave.

A rabbit coder with a deft hand, 🐾
Updated methods as per command.
Data dances with dynamic flair,
Thanks to changes made with care.

So here's to code that now adapts, 🎉
To user needs, with no mishaps.
A hop, a skip, a jump, we're done,
Celebrate the work well spun! 🥳
