SPEC - falls die Leute sehen wollten.

require 'rails_helper' 

RSpec.describe TopicPost, :type => :model do 
    it "checks if twitter handle exists" do 
    professional_safety = TopicPost.new(topic_id: "professional_safety", pub_date: "5a612420-21e2-11e6-bdf4-0800200c9a66",  author_id: 1, id: 1, message: "test", twitter_handle: "blau") 
    professional_safety.save() 
    expect(TopicPost.all.count).to eq(0) 
    end 
end 

Ich habe wirklich keine Ahnung, wie das herauszufinden. Ich bin mir nicht sicher, ob es Cequel, Rspec oder ein Edelsteinproblem ist. Kann mir jemand helfen, das zu verstehen?

Danke.

Sie müssen in Ihrer config/cequel.yml sicherstellen, dass es eine Testdatenbank wie folgt enthält.

development: 
    host: '127.0.0.1' 
    port: 9042 
    keyspace: fieldfacts_discovery 
    max_retries: 3 
    retry_delay: 0.5 
    replication: 
    class: SimpleStrategy 
    replication_factor: 1 

test: 
    host: '127.0.0.1' 
    port: 9042 
    keyspace: fieldfacts_test 

uat: 
    host: '10.0.1.228' 
    port: 9042 
    keyspace: fieldfacts_uat 
    max_retries: 3 
    retry_delay: 0.5 
    newrelic: false 
    replication: 
    class: SimpleStrategy 
    replication_factor: 1
