Комментарии:
1. Добро пожаловать в SO! Если вам нужна помощь с вашим кодом, вы должны добавить ее в вопрос. Кроме того, пожалуйста, попробуйте добавить хотя бы краткое объяснение вместо того, чтобы просто публиковать сообщение об ошибке.
2. Привет, спасибо! Как вы можете видеть, я добавил свой код, который хочу ввести в свою базу данных, но продолжаю получать сообщение об ошибке имени
3. По-прежнему недостаточно информации. У вас есть объект с именем
Borough, который создается где-то за пределами этого кода? Ошибка предполагает, что это не так. Если нет, то ваш вызовBorough.create(), конечно, может не сработать.4. Не могли бы вы показать свой файл schema.rb?
5. @JohnHanlon, я добавил свой файл schema.rb
Ответ №1:
Чтобы этот код работал:
borough.trails.create(name: trail[:Name], location: trail[:Location], park_name: trail[:park_name], length: trail[:length], difficulty: trail[:Difficulty])
Вам нужно добавить все эти атрибуты в вашу схему, чтобы у значений был атрибут для хранения. Таким образом, ваша схема должна быть обновлена с помощью миграции, чтобы включить их. Пример миграции ниже:
def change
create_table :api_v1_boroughs do |t|
t.string "name"
t.string "location"
t.string "park_name"
t.string "length"
t.string "difficulty"
t.timestamps
end
end
После миграции ваша схема должна быть такой:
ActiveRecord::Schema.define(version: 2020_11_26_183011) do
create_table "api_v1_boroughs", force: :cascade do |t|
t.string "name"
t.string "location"
t.string "park_name"
t.string "length"
t.string "difficulty"
t.datetime "created_at", precision: 6, null: false
t.datetime "updated_at", precision: 6, null: false
end
end
Комментарии:
1. Если бы проблема заключалась в отсутствующем атрибуте, ошибка была бы другой
Ответ №2:
Вы должны переместить функцию create внутри цикла:
trails.each do |trail|
case trail[:Prop_ID][0] #the first letter of the prop_id that denotes borough
when "X"
borough = Borough.find_by(name: "bronx")
when "B"
borough = Borough.find_by(name: "brooklyn")
when "M"
borough = Borough.find_by(name: "manhattan")
when "Q"
borough = Borough.find_by(name: "queens")
when "R"
borough = Borough.find_by(name: "staten island")
else
"Error: Borough not found"
end
borough.trails.create(name: trail[:Name], location: trail[:Location], park_name: trail[:park_name], length: trail[:length], difficulty: trail[:Difficulty])
end
Кроме этого, убедитесь, что вы создали модель района.
И, глядя на вашу миграцию, вы, вероятно, сделали что-то не так в пространстве имен модели.
Комментарии:
1. У меня есть модель для района, я попробую переместить свою функцию создания внутри цикла, спасибо!
