Question

I have the following model:

class test_data_urls(models.Model):
    url = models.CharField(max_length=200, db_index=True)

I want to insert a value into mysql:

cursor = connection.cursor()
url = "hiya"
cursor.execute("insert into my_table(url) values (%s)", (url))

I get an error:
‘str’ object has no attribute ‘items’

This works:

 cursor.execute("insert into my_table(url) values ('test')")

but I want to do it with %s. To me, it looks exactly like how I have always done this, so what am I missing?

Answer 1

Try using [ and ] instead of ( and ):

cursor = connection.cursor()
url = "hiya"
cursor.execute("insert into my_table(url) values (%s)", [url])

The reason that (url) does not work is because it’s not a tuple, it’s a single string. (url,) would be a tuple.
