Can't seem to get Python, Peewee, pymysql & MySql database to work no 'returning_clause' error

user2201 Published in April 25, 2018, 8:22 am

I am pretty new to Python and trying to use a very simple one table DB.

I'm using python 3, peewee and pymysql. The database is MySQL, local on my Windows 10 PC (wampserver) and the code is;

import pymysql
import MySQLdb

import peewee
from peewee import *

db = MySQLdb.connect(user='xxxxx', passwd='xxxxx',
                     host='localhost', port=3306, db='xxxxx')

class SearchUrl(peewee.Model):
    id = peewee.AutoField()
    url = peewee.TextField()
    page_title = peewee.TextField()
    date_found = peewee.DateField()
    date_last_changed = peewee.DateField()
    article_status = peewee.CharField()
    description = peewee.TextField()

    class Meta:
        database = db

newUrl = SearchUrl.create(url='http://cropnosis.co.uk', page_title="Cropnosis Ltd.",
                          date_found='2018-04-13', status='new', description='Cropnosis website')


for url in SearchUrl.filter(url='http://cropnosis.co.uk'):


Whenever I run this I get the following error in the "SearchUrl.create" line. I have searched for the 'returning_clause' attribute but have found little or no mention of it esp. with regard to MySQL.

Any help or relevant links greatly appreciated.
