Python 3.5, Django 1.10.3, Sqlite
I have deployed a django app in heroku.It ran without errors before. One day I make some change in models.py. I first do
python manage.py collectstatic,
python manage.py makemigrations,
python manage.py migrate,
heroku local web -f Procfile.windows,
the app run correctly in local. Then I push my codes to heroku. I ran:
git push heroku master
heroku run bash
$python manage.py makemigrations
$python manage.py migrate
heroku ps:scale web=1
But server returned:

    ProgrammingError at /twitter/blog/
    column twitter_article.enable_comments does not exist
    LINE 1: ...article"."content", "twitter_article"."pub_date", "twitter_a.

Here is my key model:

    from django.db import models
    from fluent_comments.moderation import moderate_model,comments_are_open, comments_are_moderated
    from fluent_comments.models import get_comments_for_model, CommentsRelation

    class Article(models.Model) :
    title = models.CharField(max_length = 100)
    category = models.CharField(max_length = 50, blank = True)
    pub_date = models.DateTimeField(auto_now_add = True)
    content = models.TextField(blank = True, null = True)
    pub_date = models.DateTimeField("pub_date")
    enable_comments = models.BooleanField("Enable comments", default=True)

    def __str__(self) :
        return self.title

    class Meta:
        ordering = ['-pub_date']

    # Optional, give direct access to moderation info via the model:
    comments = property(get_comments_for_model)
    comments_are_open = property(comments_are_open)
    comments_are_moderated = property(comments_are_moderated)

    # Give the generic app support for moderation by django-fluent-comments:
    moderate_model(Article,
        publication_date_field='pub_date',
        enable_comments_field='enable_comments',
    )

If I drop my database and build a new database. Server won't report error. Why? I'm using sqlite.

If you are versioning your migration files (most liketly) then you don't have to run makemigrations in the server again.
