Most people don’t set SSL on their server while testing and that is fine. You can disable this check in two ways: By setting an environment variable. … Read more
I decided on this problem using that. I changed the code of migration, and migration looks like this: from alembic import op import sqlalchemy as sa from sqlalchemy.dialects import postgresql def upgrade(): banner_status = postgresql.ENUM(‘active’, ‘inactive’, ‘archive’, name=”banner_status”) banner_status.create(op.get_bind()) op.add_column(‘banner’, sa.Column(‘status’, sa.Enum(‘active’, ‘inactive’, ‘archive’, name=”banner_status”), nullable=True)) def downgrade(): op.drop_column(‘banner’, ‘status’) banner_status = postgresql.ENUM(‘active’, ‘inactive’, ‘archive’, … Read more

I know, the question is rather old but I found a nice solution to this problem. You can apply filters to whole text blocks: Template Designer Documentation / Filters {% filter indent(width=4) %} {% include “./sub-template.yml.j2” %} {% endfilter %}
Create a file wsgi.py under your project with the following contents, then point Gunicorn at it. from my_project import create_app app = create_app() gunicorn -w 4 my_project.wsgi:app # -w 4 specifies four worker processes If you’re using the application factory pattern, Gunicorn allows specifying a function call like my_project:create_app(). For most cases, you can the … Read more
