prestapyt to add product ERROR

[carolinalour]

I'm trying to create a script to add products to prestashop, through Python.

 

I'm using prestapyt library; I can read files, I can get template for new file but I cannot upload a new file. This is what I have:

from prestapyt import PrestaShopWebServiceError
from prestapyt import PrestaShopWebService
from prestapyt import PrestaShopWebServiceDict

DEBUG = 'true'
PS_SHOP_PATH = MYPATH
PS_WS_AUTH_KEY = MYKEY

prestashop = PrestaShopWebServiceDict(PS_SHOP_PATH, PS_WS_AUTH_KEY, DEBUG)
myproducts = prestashop.search('products');
addNewProduct(prestashop)

where

def addNewProduct(prestashop):

blank_product = prestashop.get('products', options={'schema': 'blank'});

pprint(blank_product)

blank_product.update({

'active': '1',
'additional_shipping_cost': '',
'advanced_stock_management': '',
'description': {'language': {'attrs': {'id': '2'}, 'value': 'DESCRIPTION!!!'[spam-filter],
'description_short': {'language': {'attrs': {'id': '2'},
'value': 'SHORT DESCRIPTION!!!'[spam-filter],
'id': '23',
'id_category_default': '2',
'name': {'language': {'attrs': {'id': '2'}, 'value': 'NAME'[spam-filter],
'new': '1',
'price': '23',
'reference': 'MYREF',
'show_price': '1',
'width': ''

}) prestashop.add('products', blank_product)

 

 

When run this scrip I get the following:

 

Execute url: MYPATH/api/products / method: POST Response code: 400

Response headers:

Response body:

'PrestaShop error: 400 Bad Request. Internal error. To see this error please display the PHP errors.'

 

 

 

Any ideia?

 

 

Thanks!
