[Django]-How to check if the object has property in view in Django?

You can use hasattr() to check to see if model has the documents property.

if hasattr(self.model, 'documents'):
    doStuff(self.model.documents)

However, this answer points out that some people feel the “easier to ask for forgiveness than permission” approach is better practice.

try:
    doStuff(self.model.documents)
except AttributeError:
    otherStuff()
