请,我是django的新用户,我不明白我的模型有什么问题。 我已经激活了管理员,并创建了一个新模型:
class Strumenti(models.Model):
cod_stru = models.AutoField(db_column='cod_stru', primary_key=True)
sht_name = models.CharField(db_column='sht_name', max_length=15, blank=True, null=True)
descr = models.CharField(db_column='descr', max_length=45, blank=True, null=True)
isin = models.CharField(db_column='isin', max_length=16)
tipo = models.CharField(db_column='tipo', max_length=1)
mktcode = models.ForeignKey(Mercati, on_delete=models.CASCADE, default=1)
ccy1 = models.ForeignKey(Valute, related_name='ccyone', on_delete=models.CASCADE)
ccy2 = models.ForeignKey(Valute, related_name='ccytwo', on_delete=models.CASCADE)
beta = models.DecimalField(db_column='beta', max_digits=2, decimal_places=2, blank=True, null=True)
system = models.NullBooleanField(db_column='system', default=False, null=True)
template = models.NullBooleanField(db_column='template', default=False, null=True)
tenor = models.CharField(db_column='tenor', max_length=4, blank=True, null=True)
divy = models.DecimalField(db_column='divy', max_digits=5, decimal_places=5, blank=True, null=True)
fxpair = models.CharField(db_column='fxpair', max_length=6, blank=True, null=True)
cod_emitt = models.ForeignKey(Emittenti, on_delete=models.CASCADE, null=True)
idx_code = models.ForeignKey(Indexdef, on_delete=models.CASCADE, null=True)
vol_type = models.IntegerField(db_column='vol_type', blank=True, null=True)
def __unicode__(self):
return u'%s - %s - %s - %s' % (self.cod_stru, self.sht_name, self.descr, self.tipo)
当我尝试添加新记录时,我收到此错误:
**'ascii' codec can't encode character u'\xe3' in position 14: ordinal not in range(128)**
我正在使用Django 1.9,python 2.7,Mysql(utf8_unicode_ci)
下面是模板渲染过程中的错误
In template /usr/local/lib/python2.7/dist-packages/django/contrib/admin/templates/admin/change_form.html, error at line 33

32 {% url opts|admin_urlname:'history' original.pk|admin_urlquote as history_url %}
33 <a href="{% add_preserved_filters history_url %}" class="historylink">{% trans "History" %}</a>
有人可以帮帮我吗?

好的,我发现了问题。 我在“Valute”表中存储了“SãoTomé和Príncipe”的描述。
即使我不明白为什么我的.encode(uft-8)不能正常工作,但是像ãéí这样的字符会产生错误。 为什么我刚刚将字符串更改为“圣多美和普林西比”,现在看起来很好。
