ENUM type in SQLAlchemy with PostgreSQL

Question

I\'m using SQLAlchemy core with a postgresql database and I would like to add the ENUM type to my table definition. According to the postgresql documentatio

Answer 1

@Tim's answer is definitely correct but I wanted to offer the way I setup my ENUMs.

In my models.py I will create the values as tuples

skill_levels = ('Zero', 'A little', 'Some', 'A lot')

Then I will create a skill_level_enum variable and assign it an ENUM class with the skill level values as args.

skill_level_enum = ENUM(*skill_levels, name="skill_level")

In my table model then I pass in the skill_level_enum

class User(db.Model):
    id = db.Column(db.Integer(), primary_key=True)
    skill_level = db.Column(skill_level_enum)

I have found this makes my code a lot cleaner and I'm able to make updates to the skill_levels at the top of my file rather than scanning my models for the right thing to update.
