Odoo Python 2.7 编码 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 join / str。

Answer 1

也许如果您将连接替换为以下格式：

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

Answer 2

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

# -*- 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

因此在您的示例产品名称中已准备就绪 utf-8 unicode 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/>'))

但不使用连接，而是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)
