EF DbContext on a generic repository does not perform the expected includes when transforming the data into a...

  • EF Generic Repository Multiple Includes

    1 answer




I have a generic/base repository that I'm using and it contains different variety of methods for accessing my database.



Here's a sample:



public IQueryable<T> FindAll(string includedProperties = null)
{
var setContext = _context.Set<T>();
if (includedProperties != null)
{
foreach (var property in includedProperties)
{
setContext.Include(property);
}
}
return setContext;
}


I'm calling this method by:



var employees = _employeeRepository.FindAll(new string { "JobPosition", "Department", "EmployeeTeams", "EmployeeTeams.Team" })


When I perform a ToList() on employees, the expected navigation property is not included.



I tried switching it up and did the following:



var employees = _employeeRepository.FindAll().Include("JobPosition")
.Include("Department")
.Include("EmployeeTeams")
.Include("EmployeeTeams.Team")


And performing the ToList() includes the specified navigation property.



I want to make my approach on my generic repository work. Any ideas on how can I fix this?



NOTE: I also tried including navigation properties via expressions



(Expression<Func<T, object>> predicate)


still the same result.

          Include returns IQueryable (or IIncludableQueryable depending how you call it) so you need to add them after each other.



          Try it like this



          foreach (var property in includedProperties)
          {
          setContext = setContext.Include(property);
          }

            I was actually trying to do this but it didn't crossed my mind that I can set the DbSet<T> to queryable. Thank you for this.
