Attributes

Attributes are one of the main building blocks of data models in Hashboard. They enable things like filtering and grouping when exploring your data.

You can setup and update attributes from the Add Data Model workflow.

Attributes can either be directly added based on a column on the underlying table or query, or you can write custom SQL attributes. The latter can be useful for things like combining pre-existing columns into something more useful, e.g. CONCAT(first_name, ' ', last_name).

Types

The following attribute types are supported in Hashboard:

TypeDescription
StringsTextual data like (names, emails, etc)
NumbersNumeric values (integers, decimals, etc)
DatesTime-based data (dates, timestamps, etc)
ArraysCollections of values
BooleansTrue/false values

Configuration

Attributes can be configured with the following optional settings:

  • Description: A readable description about the attribute - this will be surfaced when doing data explorations downstream. These can also be synced directly from your database.
  • Alias: The persistent identifier for the column, corresponding to the "id" field in the DataOps Config of the attribute.
  • Primary date: This can be set on date attributes - it will be used throughout Hashboard as the default for time-based data explorations of your model.
  • Primary key: This can be set on any unique string or numeric attribute to enable joining to another model. See Model Joins for more info.
  • Binning: A default bin width for the attribute - when doing data explorations, this will be used to automatically group numeric values into buckets.
  • Make attribute hidden: When selected, this attribute will be hidden by default from the attribute tray.

Custom SQL Attributes

To add a custom SQL attribute:

  1. Create or edit the Data Model that you want to add the custom attribute to.```
  2. Under the Attributes section click the + Add Custom Attribute button.
  3. Enter your selection SQL and click the 🔄 button to test the SQL.

Deriving attributes from other attributes

Custom attributes can refer to other attributes to avoid duplicating logic.

SQL for uppercase city name
UPPER({{ city_attribute }})

SQL can reference other attributes by surrounding their alias in double curly braces. When querying, Hashboard will expand references to their full definitions.

Using joined columns in custom SQL

See Using Joined Columns in Custom SQL for more info.
