Odoo Python 2.7 Encoding utf8

Question

我正在尝试从几个字段中创建一个 unicode 字符串。我愿意：

my_unicode_text = u' '.join((u'ID ',str(order_line.product_id.id),u' | [',order_line.product_id.code,u'] ',str(order_line.product_id.name),u' | ',str(order_line.product_uom_qty),u'<br/>')).encode('utf-8').strip())

但我得到：

UnicodeEncodeError: 'ascii' codec can't encode character u'xd3' in position 18: ordinal not in range(128)

我想我没有正确使用加入/str。

Answer 1

encode用于从unicode到str而不是相反，意味着将unicode转换为bytes(在Python 2.x中str(：

# -*- coding: utf-8 -*-
s = u'aller â'
print(type(s))
print(type(s.encode('utf-8')))  # convert to str but using utf-8 codec
print(s + str(1))  # unicode + str == unicode
print(str(s))  # generate an exception because its using `ascii` codec by default

所以在你的例子中产品名称都准备好了，utf-8unicode根本不需要转换它，只需转换非字符串对象，如整数、浮点数。

my_unicode_text = u' '.join(
(u'ID ',
str(order_line.product_id.id),  # Integer
u' | [',
order_line.product_id.code,
u'] ',
order_line.product_id.name,  # utf-8 uncide (database encoding)
u' | ',
str(order_line.product_uom_qty),  # floats
u'<br/>'))

但不要使用连接，请使用字符串格式并手动转换值：

my_unicode_text = u'ID {order_line.product_id.id} | [{order_line.product_id.code}] ' 
u'{order_line.product_id.name} | {order_line.product_uom_qty}<br/>'.format(order_line=order_line)

Answer 2

也许如果您将连接替换为格式：

class Product_id:
def __init__(self, id, code, name):
self.id, self.code, self.name = id, code, name
class Order_line:
def __init__(self, product_id, product_uom_qty):
self.product_id, self.product_uom_qty = product_id, product_uom_qty

order_line = Order_line(Product_id(42, 6789, u'N{greek small letter beta}eer'), 6)
s = unicode.format(u'ID {order_line.product_id.id} | [{product_id.code}] {product_id.name} | {order_line.product_uom_qty}<br/>', order_line=order_line, product_id=order_line.product_id)
print s
