I'm try create post with language and content, and relate it on other versions of same page, but I'm get stuck
class Page(models.Model):
content = models.TextField()
language = models.CharField(max_length=7, choices=settings.LANGUAGES)
versions = models.ManyToManyField('self', blank=True)
class Meta:
unique_together = ('language', 'versions',)
This will not work properly, because Django not allow make "unique" ManyToMany fields.
Then I'm try make same relationship trough related model:
class VersionsPage(models.Model):
pass
# ToDo: add unique together here, to foreign key field
class Page(models.Model):
...
versions = models.ManyToManyField('self', blank=True, through="VersionsPage")
Anyone know how to make that without using symmetrical=False?
I think you are looking for something like this:
class Page(models.Model):
pass
class PageVersion(models.Model):
page = models.ForeignKey(Page, related_name='versions')
content = models.TextField()
language = models.CharField(max_length=7, choices=settings.LANGUAGES)
class Meta:
unique_together = ('page', 'language',)
#getting all page versions:
page = Page.objects.get(pk=some_id)
versions = page.versions.all()
