我跟隨railscast 111進行高級搜索。我得到一個未定義的局部變量或方法`find_users'。我已經按照線路排隊。不知道如何解決這個問題,因爲我做了搜索後出現錯誤。它在搜索#show中指向NoMethodError。任何幫助,將不勝感激。find_users的未定義局部變量
show.html:
搜索控制器:
def new
@search = Search.new
end
def create
@search = Search.new(params[:search])
if @search.save
redirect_to @search
else
render 'new'
end
end
def show
@search = Search.find(params[:id])
@users = @search.users
end
end
search.rb:
attr_accessible :age, :children, :ethnicity, :gender, :religion, :zip_code
def users
@users ||= find_users
private
def find_users
users = User.order(:id)
users = users.where(gender: gender) if gender
users = users.where(zip_code: zip_code) if zip_code
users = users.where(children: children) if children
users = users.where(religion: religion) if religion
users = users.where(ethnicity: ethnicity) if ethnicity
users
end
end
end
