Django mysql when saving a object got warning - mysql

Question

I was just writing a little app to store words in my mysql database using Django.I read data from a text file which is extremely well organised,like this:
The text file is like this:
DELUGE
DELUSION
DELVE
DEMAGOGUE
DEMANDING
DEMOLITION
DEMONSTRATE
DEMORALIZE
DEMOTIC
DEMUR
DENIGRATE
DENOUEMENT
DENOUNCE
DENT
DENUDE
DEPLETE
DEPLORE
DEPLOY
And then I read date from it using open('thefile').readlines like this:
for line in open('/home/jacos/sorted-gre.txt').readlines():
... if line:
... p = Word(word_spelling = line)
... p.save()
The word_spelling field is the primary key.
Then came this warning:
Traceback (most recent call last):

File "/usr/lib/pymodules/python2.7/MySQLdb/cursors.py", line 92, in _warning_check
warn(w[-1], self.Warning, 3)
Data truncated for column 'word_spelling' at row 1
As a result, only part of these words were stored in mysql. I'd like to know why.

CharFields have a max_length attribute. What did you set when you generate database
for Word.object.get(pk=1).word_spelling?
nothing related with your warning but
it's recommended to close file or open it with a with statement.
with open('/home/jacos/sorted-gre.txt') as f:
for line in f.readlines():
if line:
p = Word(word_spelling = line)
p.save()
