I am building a small rails app. When, I run heroku run rake db:migrate
, I get this error
rake aborted!
StandardError: An error has occurred, this and all later migrations canceled:
PG::UndefinedTable: ERROR: relation "categories" does not exist
: CREATE TABLE "habits" ("id" serial primary key, "name" character varying, "description" character varying, "category_id" integer, "user_id" integer, "created_at
" timestamp NOT NULL, "updated_at" timestamp NOT NULL, CONSTRAINT "fk_rails_23642321ab"
FOREIGN KEY ("category_id")
REFERENCES "categories" ("id")
, CONSTRAINT "fk_rails_541267aaf9"
FOREIGN KEY ("user_id")
REFERENCES "users" ("id")
)
In attempt to solve it, I also added this to inflections.rb
ActiveSupport::Inflector.inflections do |inflect|
inflect.irregular 'category', 'categories'
inflect.plural 'category', 'categories'
end
Which didn't help.
I also looked at few answers on stackoverflow including this, but it didn't help because I am getting this error when I run migration command.
Here is my migration files for categories and habits.
class CreateCategories < ActiveRecord::Migration[5.0]
def change
create_table :categories do |t|
t.string :name
t.timestamps
end
end
end
class CreateHabits < ActiveRecord::Migration[5.0]
def change
create_table :habits do |t|
t.string :name
t.string :description
t.integer :user_id
t.integer :category_id
t.timestamps
end
end
end
Here is my schema.rb
# This file is auto-generated from the current state of the database. Instead
# of editing this file, please use the migrations feature of Active Record to
# incrementally modify your database, and then regenerate this schema definition.
#
# Note that this schema.rb definition is the authoritative source for your
# database schema. If you need to create the application database on another
# system, you should be using db:schema:load, not running all the migrations
# from scratch. The latter is a flawed and unsustainable approach (the more migrations
# you'll amass, the slower it'll run and the greater likelihood for issues).
#
# It's strongly recommended that you check this file into your version control system.

Not sure what more I am missing!
