- Response prettyfier
$ pip install myqlIt's important to know that response is a just requests.models.Response object. Yes indeed, mYQL uses requests 😄
By default, you have access to the community tables. If for whatsoever reason you would like to not have access to those tables
>>> import myql
>>> yql = myql.MYQL(community=False)####Changing response format (xml or json)
The response format is by default json.
>>> import myql
>>> from myql.utils import pretty_json, pretty_xml
>>> yql = myql.MYQL(format='xml', community=True)
>>> resp = yql.raw_query('select name, woeid from geo.states where place="Congo"')
>>> print(pretty_xml(resp.content))

>>>####raw_query(query)
Allows you to directly type your query
>>> response = yql.raw_query("select * from geo.countries where place='North America'")
>>> # deal with the response####select(table, fields, limit).where(filters, ...)
NB : A simple select doesn't return any data. Use GET instead.
>>> response = yql.select('geo.countries', ['name', 'code', 'woeid']).where(['name', '=', 'Canada'])
>>> print(pretty_json(response.content))

}
}
}
>>>####get(table, fields, limit) Same as SELECT, but instead returns data.
REMINDER : Some tables require a where clause, therefore GET won't work on those tables, use select(...).where(...) instead .
>>> from myql.utils import dump
>>> response = yql.get('geo.countries', ['name', 'woeid'], 1)
>>> dump(response)

}
}
}
>>>####insert(table, (field1, field2, ..., fieldN),(value1, value2, ..., valueN)) Insert values into a table. Arguments 2 and 3 may be tuples or list.
>>> from myql.utils import pretty_json
>>> response = yql.insert('yql.storage.admin',('value',),('http://josuebrunel.org',))
>>> print(pretty_json(response.content))

}
}
}
}####update(table,[field1, ..., fieldN],[value1, ..., ...valueN]).where(filters, ...) Update fields values. This method is always followed by where(). Arguments 2 and 3 may be tuples or list.
>>> from myql.utils import pretty_json
>>> response = yql.update('yql.storage',('value',),('https://josuebrunel.org',)).where(['name','=','store://Rqb5fbQyDvrfHJiClWnZ6q'])

}
}
}####delete(table).where(filters, ...) Delete records
>>> from myql.utils import pretty_json

}####Using OAuth
mYQL comes with yahoo_oauth, which is an OAuth library for Yahoo! APIs.
>>> from yahoo_oauth import OAuth1
>>> oauth = OAuth1(None, None, from_file='credentials.json') # only consumer_key and consumer_secret are required.
>>> from myql import MYQL
>>> yql = MYQL(format='xml', oauth=oauth)
>>> response = yql.get_guid('josue_brunel') # Deal with the responseThe full documentation on StockScraper is here
