Sto cercando di testare la mia app Rails con Rspec, ma sto ottenendo un no implicit conversion of Symbol into Integer errore senza alcuna ragione apparente. Sulla base del traceback, penso che il problema sia legato a Mongo / Mongoid, tuttavia, non riesco a capire cosa sia esattamente. Il codice funziona perfettamente in produzione. L'errore si verifica solo durante il test.
Breve sguardo al modello senza gli altri metodi:
class Card
include Mongoid::Document
field :front, type: String
field :back, type: String
field :level, type: Integer, default: 1
field :review_date, type: DateTime, default: DateTime.now
has_many :card_statistic, dependent: :destroy
belongs_to :topic
belongs_to :user
validates :front, :back, :level, presence: true
validates :topic, presence: { is: true, message: "must belong to a topic." }
validates :user, presence: { is: true, message: "must belong to a user." }
validates :level, numericality: { only_integer: true, greater_than: 0 }
end
Una funzione nel modello che attiva l'errore:
def self.reset(card)
card.update(level: 1)
end
Il codice di prova:
it "puts the given card in level 1" do
card = create(:card)
Card.correct card
card.reload
Card.correct card
card.reload
expect(card.level).to eq(3)
card.reset
card.reload
expect(card.level).to eq(1)
end
Quindi, il traceback dell'errore che ottengo:
1) Card puts the given card in level 1
Failure/Error: Card.reset card
TypeError:
no implicit conversion of Symbol into Integer

L'errore viene attivato anche durante il test dei controller. Anche a fare un get :index getta l'errore Grazie in anticipo per il vostro aiuto.

0 per risposta № 1Apparentemente, là dove alcuni problemi con il moltole ultime build di Mongoid e I stavano estraendo il codice direttamente dal repository senza specificare una versione stabile. Quindi la soluzione era quella di eseguire il downgrade della versione su 4.0 o utilizzare la versione beta 5.0 esplicitamente.
O
gem "mongoid", "~> 5.0.0.beta", github: "mongoid/mongoid"
o
gem "mongoid", "~> 4"
invece di
gem "mongoid", "~> 5", github: "mongoid/mongoid"
