根据我的要求,我需要为所有名人投票,但如果我投票给某个名人,则不应该允许在24小时内为同一个名人投票。
Vote.rb
class Vote < ActiveRecord::Base
attr_accessible :celebrity_id, :user_id
belongs_to :user
belongs_to :celebrity, counter_cache: true
end
Celebrity.rb
class Celebrity < ActiveRecord::Base
attr_accessible :name, :gender, :category_id, :image, :votes_count
validates_presence_of :name
belongs_to :user
belongs_to :category
has_many :votes
end
我的控制器:
def vote
@celebrities = Celebrity.find(params[:id])
if current_user.votes.present?
if current_user.votes.last.updated_at < Time.now - 24.hours
@vote = current_user.votes.build(celebrity_id: @celebrities.id, :id => params[:vote])
@vote.save
end
respond_to do |format|
format.html { redirect_to ranking_screen_url }
format.json { render json: @vote, status: :created }
end
else
@vote = current_user.votes.build(celebrity_id: @celebrities.id, :id => params[:vote])
@vote.save
respond_to do |format|
format.html { redirect_to ranking_screen_url }
format.json { render json: @vote, status: :created }
end
end
end
而不是检查current_user.votes.present?
我需要检查用户是否已在投票表中投票选出了celebrity_id。任何人都可以帮助我吗?

if current_user.votes.present?
在这里,您要检查用户是否进行了投票。我认为你应该取得特定名人的用户投票。像
@celebrity = Celebrity.find(params[:id])
@vote = current_user.votes.where(celebrity_id: @celebrity.id).first
if @vote
if @vote.updated_at < (Time.now - 24.hours)
# update count here
else
else
end
