所有

运行我的rspec测试时，脚本在运行测试之前失败。看起来它在函数“up_votes”的某个地方期待“结束”，但我看不到哪里？还有什么可能吗？

Up_votes功能说明：

如果vote的值为1并且不添加它，则该函数应该添加到数组中，如果它是-1。一旦完成该循环，则应该对该数组中的总投票数（向上投票）求和。

错误输出：

/Users/user/.rvm/rubies/ruby-  2.2.1/lib/ruby/gems/2.2.0/gems/activesupport-  4.2.1/lib/active_support/dependencies.rb:274:in `require':     /Users/user/code/bloccit/app/models/post.rb:63: syntax error, unexpected end-of-input, expecting keyword_end (SyntaxError)

包含up_votes方法的Post.rb文件：

class Post < ActiveRecord::Base
 has_many :comments, dependent: :destroy
 has_many :votes
 has_one :summary
 belongs_to :user #means the post table has the user table's primary key in it
 belongs_to :topic
 mount_uploader :avatar, AvatarUploader
 default_scope {order('created_at DESC')}

 validates :title, length: {minimum: 5},  presence: true
 validates :body,  length: {minimum: 20}, presence: true



 def markdown_title
  (render_as_markdown).render(self.title).html_safe
 end


 def markdown_body
  (render_as_markdown).render(self.body).html_safe
 end

 def up_votes
  vote_array = []
  sum = 0
    vote_array = @post.votes.value.each do |vote| unless  @post.votes.value == -1
     vote_catch = vote_array
    end 
     vote_catch.each do |vote|
     sum += vote
    end 
     sum
  end
  end

正在运行Rspec测试：

require 'rails_helper'

describe Post do
describe "vote methods" do

before do
  @post = Post.create(title: 'Post title', body: 'Post bodies must be pretty long.')
  3.times { @post.votes.create(value: 1)}
  2.times { @post.votes.create(value: -1)}
end

describe '#up_votes' do
  it "counts the number of votes with value = 1" do
    expect(@post.up_votes ).to eq(3)
  end
end

describe '#down_votes' do
  it "counts the number of votes with values = -1" do
    expect(@post.down_votes ).to eq(2)
  end
end

describe '#points' do
  it "returns the sum of all down and up votes" do
    expect(@post.points ).to eq(1) # 3 - 2
  end
end
end
end

投票架构

create_table "votes", force: :cascade do |t|
 t.integer  "value"
 t.integer  "post_id"
 t.integer  "user_id"
 t.datetime "created_at", null: false
 t.datetime "updated_at", null: false
end

这可能只是你把代码放在这里但是......

vote_catch.each

与其＆＃34; end＆＃34;不符。此外，＆＃34;结束＆＃34; up_votes没有与函数的结尾对齐。

编辑：

错误是除非条件与#each方法调用配对的地方。这是一个例子：

2.2.1 :008 > x.each do |vote| unless x == -1
2.2.1 :009?>     puts vote
2.2.1 :010?>     end
2.2.1 :011?>   end
0
1
2
3
4
5
...
10
=> [0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10]
