title: Where to write predefined queries in django?
body: <p>I am working with a team of engineers, and this is my first Django project.</p>
  
  <p>Since I have done SQL before, I chose to write the predefined queries that the front-end developers are supposed to use to build this page (result set paging, simple find etc.).</p>
  
  <p>I just learned Django QuerySet, and I am ready to use it, but I do not know on which file/class to write them.</p>
  
  <p>Should I write them as methods inside each class in models.py? Django documentation simply writes them in the shell, and I haven't read it say where to put them.</p>
