Rspec检查ActiveModel ::错误

Question

有没有更好的方式来编写此规范？这个作品但是我不喜欢这个事实，我不得不打电话f.valid?得到f.errors填充。

it "fails to save the record because the name is blank" do 
    f = Foo.new 
    f.valid? 
    f.errors.include?(:name).should be_true 
end 

Answer 1

it "fails to save the record because the name is blank" do 
    Foo.create.errors.should include :name 
end
