How to localize Content of a Django application

Question

Hey, i am currently working on a django app for my studies, and came to the point of l18n. Localizing the site itself was very easy, but now i have to allow users, to transl

Answer 1

I have 2 languages on my site: English and Arabic Users can switch between languages clicking on a flag. In models i use a proxy model:

class Product(models.Model):
    name=models.CharField(max_length=100)
    name_ar=models.CharField(max_length=100, default='')

    def __unicode__(self):
        return self.name

class Product_ar(Product):
    def __unicode__(self):
        return self.name_ar
    class Meta:
        proxy=True

In forms I use 2 forms instead of one:

class CollectionEditForm_en(forms.Form):
    name = forms.CharField(label=_('Name'), max_length=100, widget=forms.TextInput(attrs={'size':'50'}))
    product = forms.ModelChoiceField(label=_('product'), queryset=Product.objects.filter(enabled=True), empty_label=None)

class CollectionEditForm_ar(forms.Form):
    name = forms.CharField(label=_('Name'), max_length=100, widget=forms.TextInput(attrs={'size':'50'}))
    product = forms.ModelChoiceField(label=_('product'), queryset=Product_ar.objects.filter(enabled=True), empty_label=None)

In code check language this way:

if request.LANGUAGE_CODE=='ar':
    CollectionEditForm=CollectionEditForm_ar
else:
    CollectionEditForm=CollectionEditForm_en

So in templates i check:

{% if LANGUAGE_CODE == "ar" %}
  {{product.name_ar}}
{% else %}
  {{product.name}}
{% endif %}

Hope this solution will help somebody
