I have a property on my entity, that does not exist in the database, so during entity configuration, I ignore it:
builder.Ignore(m => m.MaxDeliveryAttempts);
However I need this property to be by default set to a value I get from my appsettings.json file.
I can get IOptions
injected into by DbContext, but I cannot figure out how to force EF to set the value of MaxDeliveryAttempts
from settings when it instantiates the entity.
Is it even possible?
You can configure the default value. For example:
protected override void OnModelCreating(ModelBuilder modelBuilder)
{
modelBuilder.Entity<Blog>()
.Property(b => b.Rating)
.HasDefaultValue(3);
}
