UnknownAttributeError on Heroku but not local

Getting an UnknownAttributeError when trying to create a model instance in production. Works fine locally, but not on Heroku.

ActiveRecord::UnknownAttributeError: unknown attribute 'team_id' for Membership

After a user signs up, the first thing they do is create a team. If the team saves, then teams#create makes them a member of that team. 

Membership.create(user_id: current_user.id, team_id: @team.id )

Team has_many :users, through: :memberships and User has_many :teams, through: :memberships.

class Membership < ActiveRecord::Base
  belongs_to :user
  belongs_to :team

  validates :user_id, presence: true
  validates :team_id, presence: true
end

Even looks like team_id is on the Membership table on Heroku, so I am very confused...

  SQL (0.9ms)  INSERT INTO "schema_migrations" ("version") VALUES ($1)  [["version", "20150502213611"]]
   (1.3ms)  COMMIT
Migrating to CreateMemberships (20150502215929)
   (0.5ms)  BEGIN
== 20150502215929 CreateMemberships: migrating ================================
-- create_table(:memberships)
   (7.4ms)  CREATE TABLE "memberships" ("id" serial primary key, "user_id" integer, "team_id" integer, "created_at" timestamp NOT NULL, "updated_at" timestamp NOT NULL) 
   -> 0.0079s
== 20150502215929 CreateMemberships: migrated (0.0080s) =======================

Again, no problems locally, only on Heroku.

Running Rails 4.2.1

I had the same unknownattribute error despite the attribute clearly existing in my model. As far as I can tell it's an error from heroku's end. I fixed it with: 

heroku restart

This magically started working a minute ago. No idea why.
