EntityFramework-Plus check if data implements an interface
Question
I have a filter
this.Filter<BaseModel>(q => q.Where(x => x.CompanyId == companyId);
Is there a way to check whatever "x" is implementing my custom interface "IGlobalDatabaseObject" ?
this.Filter<BaseModel>(q => q.Where(x => x.CompanyId == companyId || x is IGlobalDatabaseObject ); ?
So, the db queries will return the data where "x.CompanyId== companyId" or if that data implements Global Interface
I am using Ef plus library (github.com/zzzprojects/EntityFramework-Plus )
Accepted Answer
I think you are seeking for EF+ Query Filter Enable/Disable feature. In your case, something like this:
// The key identifying your filter
var key = new object();
// Create filter for classes that inherit BaseModel
this.Filter<BaseModel>(key, q => q.Where(x => x.CompanyId == companyId));
// Disable the filter for classes that implement IGlobalDatabaseObject
this.Filter<IGlobalDatabaseObject>(key).Disable();
