It seems that StringListProperty can only contain strings up to 500 chars each, just like StringProperty...
Is there a way to store longer strings than that? I don't need them to be indexed or anything. What I would need would be something like a "TextListProperty", where each string in the list can be any length and not limited to 500 chars.
Can I create a property like that? Or can you experts suggest a different approach? Perhaps I should use a plain list and pickle/unpickle it in a Blob field, or something like that? I'm a bit new to Python and GAE and I would greatly appreciate some pointers instead of spending days on trial and error...thanks!
Alex already answered long ago, but in case someone else comes along with the same issue:
You'd just make item_type
equal to db.Text (as OP mentions in a comment).
Here's a simple example:
from google.appengine.ext import db
class LargeTextList(db.Model):
large_text_list = db.ListProperty(item_type=db.Text)
def post(self):
# get value from a POST request,
# split into list using some delimiter
# add to datastore
L = self.request.get('large_text_list').split() # your delimiter here
LTL = [db.Text(i) for i in L]
new = LargeTextList()
new.large_text_list = LTL
new.put()
def get(self):
# return one to make sure it's working
query = LargeTextList.all()
results = query.fetch(limit=1)
self.render('index.html',
{ 'results': results,
'title': 'LargeTextList Example',
})
You can use a generic ListProperty with an item_type
as you require (str
, or unicode
, or whatever).
