c# - Where to call database in method on model? -

In an MVC app with unit framework 4, I try to add some more code to schedule I am the ideal. At present, a method on this model is called the code to get the list of dates that are not at the end of the week. The model is called the controllers in this way var freedata = schedule. GateDettyTiltressDid () .

To do the above, no database call is necessary, I want to add a method which checks that the date is "Structural Free Day" (free every year). This method needs to create a database call because the free day will be stored in the Structural Friede model via String Day Mean ^{(maybe I use date time The tax and the year will ignore the part, though the leap will look out for the year - this is another problem)} and string reason .

  // Get the list of dates for the next 30 days) who are eligible for duty, static static ICollection & lt; DateTime & gt; GetDatesNextThirtyDays () {ICollection & lt; DateTime & gt; PlannableDates = New List & lt; DateTime & gt; (); Var date = DateTime.Today; For (var i = 0; i & lt; 29; i ++) {if (!!! (date!) And; easertical free day (date)) // & lt; = New method {PlannableDates.Add (date); } Date = date Add days (1); } Return planable dates; } // Return is true that the day is not Saturday, Sunday Public Static Bull ISKCend (Datetime Day) {Return day.Date.DayOfWeek == DeFoyeke Saturday || day. date. Diaf wake == day off }  

I like to add new method bool ISStructuralFreeDate to the GetDatesNextThirtyDays method with the database call, because it is used . Is it OK to instantify dBContext and calls the database in the model? Or is there a great solution?
