Example code:
def save(self):
regex = re.compile("\{\{([^\}]{2,60})\}\}")
words = regex.findall(self.body)
self.body = regex.sub("\\1",self.body)
super(Chapter,self).save()
for word in words:
if len(word.strip()) > 0:
try:
self.keywords.create(value=word.strip().title())
except Exception, e:
print e
print self.keywords.all() # This prints the correct keywords!
super(Chapter,self).save()
The outcome of this code is that new Keywords are created, but they
are not bound to this Chapter.
Simply calling chapter.keywords.create(value="Test") will indeed
create a new keyword with the value "Test" bound to the chapter. I am
running this from the django admin btw.
The problem seems to be in the
django.db.models.fields.related._add_items method, somewhere around
line 340.
The fact is that the insertion query is executed, but for some reason
it is not committed, perhaps it is a transaction issue?
It is simply broken when called from within the save() method of a
Model instance...
I haven't started a ticket because I am not sure if this is bug or a
feature ;-)
