Welcome to the documentation for django-klingon!

django-klingon is an attempt to make django model translations suck but with no integrations pain in your app!

Setup & Integration

In your settings files: add django-klingon to INSTALLED_APPS:

INSTALLED_APPS = (
    ...
    'klingon',
    ...
)

specify a default language if you want to use your fields to store the default language:

KLINGON_DEFAULT_LANGUAGE = 'en'

Extend you models to add API support: first add Translatable to your model Class definition. This will add the API functions:

from klingon.models import Translatable
...
class Book(models.Model, Translatable):
...

in the same model add an attribute to indicate which fields will be translatables:

...
translatable_fields = ('title', 'description')
...

your model should look like this:

class Book(models.Model, Translatable):
    title = models.CharField(max_length=100)
    description = models.TextField()
    publication_date = models.DateField()

    translatable_fields = ('title', 'description')

Add admin capabilities:

you can include an inline to your model admin and a custom action to create the translations. To do this in your ModelAdmin class do this:

from klingon.admin import TranslationInline, create_translations
...
class BookAdmin(admin.ModelAdmin):
    ...
    inlines = [TranslationInline]
    actions = [create_translations]

see full example in example_project folder of source code of klingon

Using Specific Widgets in the TranslationInline form of the admin:

You can specify the widget to be use on an inline form by passing a dictionary to TranslationInlineForm. So, you might want to extend the TranslationInline with a new form that will a "widgets" dictionary, where you can specify the widget that each filds has to use, for example:

class RichTranslationInlineForm(TranslationInlineForm):
    widgets = {
        'CharField': forms.TextInput(attrs={'class': 'klingon-char-field'}),
        'TextField': forms.Textarea(attrs={'class': 'klingon-text-field'}),
    }

class RichTranslationInline(TranslationInline):
    form = RichTranslationInlineForm

and then you just simply use the RichTranslationInline class on your AdminModels, for example:

class BookAdmin(admin.ModelAdmin):
    inlines = [RichTranslationInline]

see full example in example_project folder of source code of klingon

Using the API

To create the translation you can do the follwing:

Suppose that you have and object called book:

> book = Book.objects.create(
    title="The Raven",
    description="The Raven is a narrative poem",
    publication_date=datetime.date(1845, 1, 1)
)

you can create translation for that instances like this:

> book.set_translation('es', 'title', 'El Cuervo')
> book.set_translation('es', 'description', 'El Cuervo es un poema narrativo')

a translation could be access individually:

> self.book.get_translation('es', 'title')
'El Cuervo'
> book.get_translation('es', 'description')
'El Cuervo es un poema narrativo'

or you can get all translations together:

> self.book.translations('es')
{
    'title': self.es_title,
    'description': self.es_description,
}

Installation:

pip install django-klingon
