Add `ResourceModel.FindAll` implementation for BadgerDB

[jim-junior]

Description

Add the FindAll method in

conveyor/internal/models/resource.go

Line 159 in 2572f4c

func (m *ResourceModel) FindAll(resourceType string) ([]string, error) {

impelementation for BadgerDB. This method is responsible for retrieving the full data content of all resources belonging to a specific type from the local key-value store.

Requirements

• File Location: internal/models/resource.go
• Transactionality: Use a BadgerDB View (read-only) transaction.
• Prefix Scanning & Value Retrieval:
  • Utilize a BadgerDB Iterator to scan for all keys starting with the prefix: /resources/{resourceType}/.
  • Unlike the List method, this method must retrieve the Value associated with each key.
  • The implementation must include logic to filter out versioned sub-keys (e.g., /resources/type/name/1) to ensure only the primary resource objects are returned in the result set.
• Data Extraction: Collect the values as a slice of strings (representing JSON data).
• Error Handling: If no resources are found for the given type, return a "no resources found" error to maintain parity with the current implementation.
• Dependency Injection: The method must use the injected *badger.DB instance.
• Testing: A corresponding test case must be created in internal/models/resource_test.go.

Success Criteria

• The FindAll method successfully iterates through BadgerDB and retrieves full resource values.
• The method correctly filters out versioned keys and only returns primary resource data.
• The iterator is correctly handled and closed to prevent resource leaks.
• Test Case implementation: A unit test is provided that:
  • Pre-populates an in-memory BadgerDB with several resources of the same type (including versioned entries).
  • Calls FindAll for that type.
  • Asserts that the returned slice contains the correct number of items and the data matches the primary entries only.
  • Verifies that the method returns the expected error when scanning an empty resource type.
