Answer 1

I'm going to assume that you have a previous migration in which you've already added the short_description_eng field. You could check this by looking through the previous migration files for the string 'short_description_eng'. If thats True, you can just delete the following from the 0002_auto_20160315_1544 migration file.

migrations.AddField(
    model_name='words',
    name='short_description_eng',
    field=models.CharField(blank=True, default='', max_length=100, verbose_name='Условное обозначение Eng'),
),

If that isn't the case then its possible you've got your database in a foobar'ed state and it may be worth deleting it (assuming this is a development database) and recreating it.
