How heroku run python manage.py migrate?
<p>I deployed a simple Django app in Heroku</p>

<p>Steps:</p>

<pre><code>- git push heroku master

- heroku run python manage.py makemigrations ( or + app_name)
</code></pre>

<p>it seem to affect:</p>

<pre><code>  0002_main.py:
- Create model Comment
- Remove field status from match
- Remove field quantity from slot
- Add field avatar to account
- Add field slots to match
- Alter field verification_code on account
- Alter field verification_code on slot
- Add field match_object to comment
- Add field user to comment
- Alter index_together for comment (1 constraint(s))
</code></pre>

<p>then I run</p>

<pre><code>- heroku run python manage.py migrate
</code></pre>

<p>but i received:</p>

<pre><code>  Running migrations:
  No migrations to apply.
  Your models have changes that are not yet reflected in a migration, and so won't be applied.
  Run 'manage.py makemigrations' to make new migrations, and then re-run 'manage.py migrate' to apply them.
</code></pre>
