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 dopython 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.
