レンダリング中にUnicodeEncodeErrorが発生しました： 'ascii'コーデックは4-5桁の文字をエンコードできません：序数は範囲外です（128）

Question

こんにちは私はポーランドに住んでいるので、łóźćなどの手紙を扱わなければなりません。 、管理パンネルに、「ZespółSzkół」などのテキストを追加し、私はこのようなエラーが出る：UnicodeEncodeErrorををキャッチ

レンダリング中：「ASCII」コーデックが位置4-5で 文字をエンコードすることはできません：序ない範囲で（ 128）

私は同様の問題の多くStackoverflowページで見たが、私はどのように私の問題を解決するためのアイデアはありません。

マイDatabseは私のDBのMySQLの

Unicodeのコレクションです：utf8_unicode_ci内

マイmodels.py

# -*- coding: utf-8 -*- 
from django.db import models 
import codecs 

...  

class experience(models.Model): 
    dateStart = models.DateField() 
    dateEnd = models.DateField() 
    company = models.CharField(max_length=50) 
    position = models.CharField(max_length=50) 
    description = models.TextField(max_length=255) 
    def __unicode__(self): 
     return self.company.decode('utf8')

Answer 1

あなたの__unicode__メソッドは、残念ながらナンセンスです。

decodeは、バイトコードをユニコードに変換するためのものですが、self.companyはです。すでにユニコードです。したがって、decode('utf-8')を呼び出すと、Pythonはそれを暗黙的に最初にバイトコードにエンコードする必要があります。これはデフォルトのasciiエンコーディングによって行われます。アクセント付きの文字があるとすぐに失敗します。

私はあなたがその方法で何をしようとしているのか分かりませんが、__unicode__メソッドは常にユニコードを返さなければなりません。ちょうどreturn self.companyはここで正しいことです。
