Goal

Create a freeware library to run translation of fields without need to restart the server, without changing model code, storing the translations in database and ability to search all translations, current language or by translations of a specify language.

Problem

Existing solutions for their approach are divided into those who store the translation in a separate column of the main table and on those who store the translation in separate tables for each model. These approaches overlap the restriction is that if you want to start to translate a new field or model you are making changes in the structure of the database and in consequence of what is necessary server restart. In parallel with this, the majority of decisions to make make changes to the model code making it more difficult to understand.

Solution

To solve the problems it is proposed to develop a Django application that would allow to store in one table a reference to a field in the model, and in another - translations in a shared table with a static structure would not change the standard scenario of using ORM fields and would not require server restart.

Usage scenario

class Book(models.Model):
    title = models.CharField(_('Title'), max_length=250, default='', blank=True, null=False)
    active = models.BooleanField(_('active'), default=False)
    sort = models.IntegerField(_('sort'), default=0, blank=True, null=True)
    book = Book.objects.create(title='Title')

Then the title field is added to the table of translated fields TranslatableFields. Programmatically or through the admin interface:

fld = TranslatableFields.objects.create(
    name='title',
    content_type=ContentType.objects.get_for_model(Book),
)

And in the translation table added translation for the instance. Programmatically or through the admin interface:

Translations.objects.create(
    content_object=book,
    field=fld,
    lang=Language.objects.get('en'),
    value='en',
)

Then you can interact with model Book:

from django.utils.translation import activate

activate('en')
book = Book.objects.first()
book.title  # => Title en

Prototypes of interfaces:

In the first approximation of the interfaces you will need a widget for translatable fields.

Where the tab with an active language are marked with a blue colour.

Not empty bookmarks are marked in dark.

Also, at the end of bookmarks, you need to add a bookmark with the + symbol by clicking which opens the language selection dialog. The selected language appears as bookmark.
