ERROR: relation "coupons_models_coupons" does not exist

[jessesanford]

Followed installation instructions as best as I could. I imagine there might be an generate coupons:install step that I am missing? Nothing in the readme about it. Anyone else getting this?

PG::UndefinedTable: ERROR: relation "coupons_models_coupons" does not exist LINE 5: WHERE a.attrelid = '"coupons_models_coupons"'... ^ : SELECT a.attname, format_type(a.atttypid, a.atttypmod), pg_get_expr(d.adbin, d.adrelid), a.attnotnull, a.atttypid, a.atttypmod FROM pg_attribute a LEFT JOIN pg_attrdef d ON a.attrelid = d.adrelid AND a.attnum = d.adnum WHERE a.attrelid = '"coupons_models_coupons"'::regclass AND a.attnum > 0 AND NOT a.attisdropped ORDER BY a.attnum

Yes, you'll need to run the rake task coupons:install:migrations.

From bundle exec rake -T:

rake coupons:install:migrations         # Copy migrations from coupons to application

This will copy over the migration template. Running this migration creates the two tables you need: coupons and coupon_redemptions.

It's missing from the install guide.

For reference, here's my schema.rb:

  create_table "coupon_redemptions", force: :cascade do |t|
    t.integer  "coupon_id",  null: false
    t.string   "user_id"
    t.string   "order_id"
    t.datetime "created_at", null: false
    t.datetime "updated_at", null: false
  end

  create_table "coupons", force: :cascade do |t|
    t.string   "code",                                    null: false
    t.string   "description"
    t.date     "valid_from",                              null: false
    t.date     "valid_until"
    t.integer  "redemption_limit",         default: 1,    null: false
    t.integer  "coupon_redemptions_count", default: 0,    null: false
    t.integer  "amount",                   default: 0,    null: false
    t.string   "type",                                    null: false
    t.datetime "created_at",                              null: false
    t.datetime "updated_at",                              null: false
    t.text     "attachments",              default: "{}", null: false
  end

I have had this gem running merrily in production for about 5-6 months, so you should be able to achieve the same 👍

@LuisHCK You need to run rake coupons:install:migrations — note the last part; :migrations.
This is the only rake task included with the gem (ie. there is no coupons:install)
