Hey Cyllo community! When's the best time to use `@api.depends_context`? I'm a bit confused on when it's really necessary. Any examples or explanations would be awesome!

Here's how to use the '@api.depends_context' decorator in Odoo to make your computed fields aware of context values. This ensures your computed fields are recalculated when relevant context values change.
For example,
class ProductTemplate(models.Model):
_inherit = 'product.template'
discount_price = fields.Float(compute='_compute_discount_price')
@api.depends_context('discount_rate')
def _compute_discount_price(self):
for product in self:
discount_rate = self.env.context.get('discount_rate', 0.0)
product.discount_price = product.list_price * (1 - discount_rate / 100)
The 'depends_context' decorator specifies which context keys a non-stored "compute" method depends on. Each argument represents a key in the context dictionary.
