Question 1

How to save a document with validation in Astronomy?

Accepted Answer

Use the save() method on a model instance, which automatically validates fields based on the schema and updates only changed fields in the database. This combines validation and persistence in one call, as shown in the README example with the Post model.

Question 2

Astronomy vs SimpleSchema: which should I use for Meteor?

Accepted Answer

Astronomy provides a full model layer with behaviors and change tracking, while SimpleSchema focuses solely on schema validation. Choose Astronomy if you need an ORM-like experience with reduced boilerplate; SimpleSchema is lighter for validation only in existing Meteor setups.

Question 3

How to add automatic timestamps to models in Astronomy?

Accepted Answer

Use the timestamp behavior in the schema definition. For example, add 'behaviors: { timestamp: {} }' to automatically set createdAt and updatedAt fields, as demonstrated in the sample Post model from the README.

Question 4

Can Astronomy handle nested documents or arrays in schemas?

Accepted Answer

Yes, Astronomy supports nested fields and arrays in schemas. Define them in the fields object with appropriate types, and validation and type conversion will apply recursively, though complex nesting might require careful configuration.

Question 5

What happens if validation fails when saving a document in Astronomy?

Accepted Answer

The save() method will throw a validation error with details on which fields failed. You can catch this error and handle it appropriately, such as displaying user-friendly messages or logging issues for debugging.

Question 6

How does Astronomy integrate with Meteor's reactive data sources?

Accepted Answer

Astronomy models can be used within Meteor's reactive contexts like Tracker.autorun, and changes to model instances will trigger reactivity. However, ensure to use Astronomy methods for updates to maintain consistency with the model layer.
