Ruby on Rails：带有关键字和日期范围的搜索表单不起作用

Question

this is beginner of Ruby on rails. I'm adding search box in index view and want to search with keyword and date range. Keyword search works well, but if I contains date range, it returns nothing. bit confused, So I post here.

• search action that implemented in Model is like this.

def self.search(search, date_from, date_to)

        if !date_from.blank? && !date_to.blank?
            @searched_private_questions = self.where(" asktime BETWEEN ? AND ? ", "#{date_from}", "#{date_to}" )
        else
            @searched_private_questions = PrivateQuestion.all
        end

        if !search.blank?
            #search with user name first
            searched_user = User.where( 'name LIKE ?', "%#{search}%" )
            if !searched_user.empty?
                @searched_private_questions = @searched_private_questions.where(user: searched_user).order(:asktime)
            else
                #if search keyword is not username, search in title and body context
                @searched_private_questions = @searched_private_questions.where('title LIKE ? OR body LIKE ?', "%#{search}%","%#{search}%").order(:asktime)
            end
        else
            @searched_private_questions = @searched_private_questions.order(:asktime)
        end


    end

search (keyword) and date_from, date_to parameters are transfered well. but if I insert date_from and date_to parameters, nothing returns from where clause.

Can be related with pagination code?

• in controller index action is like this:

def index
    @searched_private_questions = PrivateQuestion.search(params[:search], params[:date_from], params[:date_to])
    @pagy, @private_questions = pagy(@searched_private_questions, items:10) 
  end

I'm using rails 5 and bootstrap 3 with cdn, and bootstrap datepicker. datepicker works well. I wish someone help me... Thanks.

I found interesting points,..;;;!!! it works if I execute this in production environment, which connects to PostgreSQL database. Might be related to sqllite settings. Anyway it works in production ENV! Sorry for confusing ;;;
