Models

Methods, tips, and tricks for working with Django Models

from ..models import Post
 
# all posts
posts = Post.objects.all()
# filtered by field
posts = Post.objects.filter(pub_date__year=2020) # can chain additional .filter() 
# queries are done lazily and won't be ran until necessary
posts = posts.filter(pub_date__month=12)
 
print(posts) # now the query actually runs

'' filters for queries <code python> # use a (dunder) after a field name to access different forms of it ie posts = Post.objects.filter(title=“A New Title”) posts = Post.objects.filter(titlecontains=“New”) # can also use icontains for case insensitive posts = Post.objects.filter(titlestartswith=“A”) posts = Post.objects.filter(pub_date__year=2020) # can also use month, day </code> —
