Hi,
A small correction in the solution above,
phrase = Phrases.get_by_id(2)
# or
phrase = Phrases.get_by_key_name('my_key_2')
phraseContent = 'typing a longer phrase'
#Correction
#phraseContent.put()
phrase.phraseContent = phraseContent
phrase.put()
or
phrase.phraseContent = 'typing a longer phrase'
phrase.put()
Thanks,
Arun Shanker Prasad.
