Context.update(other_dict)
[source]
In addition to push()
and pop()
, the Context
object also defines an update()
method. This works like push()
but takes a dictionary as an argument and pushes that dictionary onto the stack instead of an empty one.
>>> c = Context() >>> c['foo'] = 'first level' >>> c.update({'foo': 'updated'}) {'foo': 'updated'} >>> c['foo'] 'updated' >>> c.pop() {'foo': 'updated'} >>> c['foo'] 'first level'
Like push()
, you can use update()
as a context manager to ensure a matching pop()
is called.
>>> c = Context() >>> c['foo'] = 'first level' >>> with c.update({'foo': 'second level'}): ... c['foo'] 'second level' >>> c['foo'] 'first level'
New in Django 1.9:
The ability to use update()
as a context manager was added.
Using a Context
as a stack comes in handy in some custom template tags.
