Django：在视图中访问时，settings.py中的重要字符被破坏 [英] Django: Accented characters in settings.py are broken when accessed in a view
问题描述
这里是view.py中的代码：
from django .conf导入设置
def getValueFromSetting（request）：
mimetype ='application / json'
charset = utf-8'datasources = getattr（settings，'MY_CONSTANT_NAME'，[ ]）
config ='{'
config + ='datasources：'+ str（datasources）.replace（'，''）
config + ='}'
return HttpResponse（config，mimetype）
解决问题：
- 我把＃ - - 编码：utf-8 - 我的settings.py和我的views.py
- 我在设置中的特殊字符前加了u'ô'或unicode（'ô'）。
- 我尝试了所有可能的.decode（'utf-8'），.encode（'utf-8'），在settings.py中或在views.py ... $ b中的特殊字符上的'8'），.decode（'iso-8859-1'），.encode（'iso-8859-1' $ b
没有解决问题的方法。
有任何建议可以解决这个问题吗？
谢谢
Etienne
我假设您在浏览器中看到这些 \xc3\xb4 字符串。您是否尝试编辑模板文件以在HTML标题中定义正确的字符集？
< head>
< meta name =descriptioncontent =example/>
< meta name =keywordscontent =something/>
< meta name =authorcontent =Etienne/>
< meta charset =UTF-8/> <！ - < ----这一行 - >
< / head>
在此答案中的第一则留言之后编辑：
我怀疑 getattr 不能用于 ascii 编码。
从django.conf导入设置
def getValueFromSetting（request）：
myConstantValue = settings.MY_CONSTANT_NAME
＃检查myConstantValue here
$ b b
在最后一条评论后修改：
我想现在我明白你的问题了。你不喜欢视图返回的JSON只有ASCII的事实。我建议您使用与Python捆绑的 json 模块提供的 dumps 函数。下面是一个例子：
＃ - * - coding：utf-8 - * -
＃ b $ b import json
def dumpjson（request）：
response = HttpResponse（json.dumps（settings.CONSTANT_TUPLE，encoding ='utf-8'，ensure_ascii = False），content_type = 'application / json'）
返回响应
CONSTANT_TUPLE 在示例中只是我的 settings.py 中的 DATABASES 。
这里的重要一点是 ensure_ascii = False 。你能试试吗？这是你想要的吗？
I have accented characters in my settings.py that I access in a view using getattr(settings, 'MY_CONSTANT_NAME', []) but the getattr() call return broken characters (for example, "ô" become: "\xc3\xb4").
here is the code in view.py:
from django.conf import settings
def getValueFromSetting(request):
mimetype = 'application/json'
charset=utf-8' datasources = getattr(settings, 'MY_CONSTANT_NAME', [])
config= '{'
config+= '"datasources": ' + str(datasources).replace("'", '"')
config+= '}'
return HttpResponse(config,mimetype)
What I have done so far to try to solve the problem:
- I put # -- coding: utf-8 -- as the first line of my settings.py and my views.py
- I put u'ô' or unicode('ô') in front of special characters in settings.py
- I put DEFAULT_CHARSET = 'utf-8' in settings.py
- I try all possible combination of .decode('utf-8'), .encode('utf-8'), .decode('iso-8859-1'), .encode('iso-8859-1') on the special characters in settings.py or in the views.py...
Nothing solve the problem.
Any suggestion to solve this problem?
Thank you

I assume you're seeing these \xc3\xb4 strings in your browser.. Have you tried editing your template file to define the proper charset in the HTML header?
<head>
<meta name="description" content="example" />
<meta name="keywords" content="something" />
<meta name="author" content="Etienne" />
<meta charset="UTF-8" /> <!-- <---- This line -->
</head>
Edit after your first comment in this answer:
I suspect getattr will not work with other than ascii encoding. Do you think something like the following will not do what you want?
from django.conf import settings
def getValueFromSetting(request):
myConstantValue = settings.MY_CONSTANT_NAME
# check myConstantValue here
Edit after last comments:
I think now I understand your problem. You don't like the fact that the JSON returned by the view is ASCII-only. I recommend you to use dumps function provided by the json module bundled with Python. Here's an example:
# -*- coding: utf-8 -*-
# other required imports here
import json
def dumpjson(request):
response = HttpResponse(json.dumps(settings.CONSTANT_TUPLE, encoding='utf-8', ensure_ascii=False), content_type='application/json')
return response
The CONSTANT_TUPLE in the example is just a copy of DATABASES in my settings.py.
The important bit here is ensure_ascii=False. Could you try it? Is that what you want?
