I have installed python 2.7 64bit,MySQL-python-1.2.3.win-amd64-py2.7.exe.
I use the following code to insert data :
class postcon:
def POST(self):
conn=MySQLdb.connect(host="localhost",user="root",passwd="mysql",db="dang",charset="utf8")
cursor = conn.cursor()
n = cursor.execute("insert into d_message (mid,title,content,image) values(2,'xx','ccc','fff')")
cursor.close()
conn.close()
if n:
raise web.seeother('/')
This results in printing n as 1, but in mysql client data aren't visible.
google says I must add conn.autocommit(True).
but I don't know why MySQLdb turns it off;
I don't know if there's a specific reason to use autocommit with GAE (assuming you are using it). Otherwise, you can just manually commit.
class postcon:
def POST(self):
conn=MySQLdb.connect(host="localhost",user="root",passwd="mysql",db="dang",charset="utf8")
cursor = conn.cursor()
n = cursor.execute("insert into d_message (mid,title,content,image) values(2,'xx','ccc','fff')")
conn.commit() # This right here
cursor.close()
conn.close()
if n:
raise web.seeother('/')
Note that you probably should check if the insert happened successfully, and if not, rollback the commit.
by default MySQLdb autocommit is false,
You can set autocommit to True in your MySQLdb connection like this,
conn=MySQLdb.connect(host="localhost",user="root",passwd="mysql",db="dang",charset="utf8")
conn.get_autocommit() #will return **False**
conn.autocommit(True)
conn.get_autocommit() #Should return **True** now
cursor = conn.cursor()
