php - Codeigniter - load a model in my library -

i'm write own library in codeigniter check if logged in user admin or not. need compare value value of typeaccount in db. because i'm still learning mvc pattern had question before starting write library. can load model in library? or should communicate directly db in library? or there better way approach this?

since library kind of logic, can see piece of controller. controller loads model use it.

so yes load model codeigniter instead of connecting database yourself.

makes code more dry too.
