用Parler在Django管理界面中创建自定义表单

Question

我有一个django 1.8实例(和python 2)，我正在使用django-parler进行翻译。我想定制管理界面(我想使用django-autocomplete-light，但这与此无关)。但是用parler定制管理界面似乎比我想的要复杂一些。下面是一个简化的例子。

models.py

from django.db import models
from parler.models import TranslatableModel, TranslatedFields


class Fruits(TranslatableModel):
    translations = TranslatedFields(
        fname=models.CharField(max_length=200)
    )

    def __unicode__(self):
        return self.fname

forms.py

from dal import autocomplete
from django import forms

from .models import Fruits

class FruitsForm(forms.ModelForm):
    class Meta:
        model = Fruits
        fields = (
            'fruits',
        )

admin.py

from django.contrib import admin
from parler.admin import TranslatableAdmin

from .forms import FruitsForm
from .models import Fruits


class FruitsAdmin(TranslatableAdmin):
    form = FruitsForm
    model = Fruits


admin.site.register(Fruits, FruitsAdmin)

问题

django.core.exceptions.FieldError: Unknown field(s) (fruits) specified for Fruits

我能做什么?

编辑#1:

经过一些搜索之后，我相信您必须使表单继承自parler.formsTranslatableModelForm，这样才能按预期工作。

更改您的FruitsForm以匹配以下内容：

from dal import autocomplete
from django import forms
from parler.forms import TranslatableModelForm

from .models import Fruits

class FruitsForm(TranslatableModelForm):
    class Meta:
        model = Fruits
        fields = (
            'fname',
        )

如果fname给出了相同的问题，请尝试设置fields='__all__'

祝你好运:)
