Hello, I'm Philippe from switzerland,
I'm writing using python a small JSON API for a mycology photos archive
webapp. Aside the main API endpoint are two
helpers for an autocomplete form.
Here is the first one:
--8<--
@app.route('/genus/<genus>')
def genus(genus):
with dbconn.cursor() as cur:
cur.execute("""SELECT myco.genus.name
FROM myco.genus
WHERE myco.genus.name LIKE %s""", (genus.upper()+'%',))
lsgenus = cur.fetchall()
ls = []
for genus in lsgenus:
ls.append(genus[0])
return jsonify(ls)
--8<--
My questions:
- What is the best way to use in psycopg3 to express a SELECT ... WHERE
... LIKE blah% ?
- Is my code above safe or vulnerable to a injection attack?
- What peoples having passed on the same pattern have to recommend?
Thanks!
