Class WorkflowHistoryDbContext

Namespace

JD.AI.Workflows.History

Assembly

JD.AI.Workflows.dll

Minimal EF Core DbContext for persisting workflow history graph nodes and edges. Mirrors the HistoryNodeEntity/HistoryEdgeEntity tables in the WorkflowFramework dashboard database (SQLite) without a hard dependency on the Dashboard.Persistence project.

Methods

OnModelCreating(ModelBuilder)

Override this method to further configure the model that was discovered by convention from the entity types exposed in DbSet<TEntity> properties on your derived context. The resulting model may be cached and re-used for subsequent instances of your derived context.

protected override void OnModelCreating(ModelBuilder modelBuilder)

Parameters

modelBuilder ModelBuilder

The builder being used to construct the model for this context. Databases (and other extensions) typically define extension methods on this object that allow you to configure aspects of the model that are specific to a given database.

Remarks

If a model is explicitly set on the options for this context (via UseModel(IModel)) then this method will not be run. However, it will still run when creating a compiled model.

See Modeling entity types and relationships for more information and examples.
