我在搜索我的数据库时使用 jquery 日期选择器来选择两个日期。目前，搜索只会搜索确切的开始日期和确切的结束日期，但我希望用户能够选择两个日期，他们可以在这些日期之间进行搜索。
这是我的模型：
class Project < ActiveRecord::Base
attr_accessible :business_div, :client, :customer_benifits, :edited_date, :end_date, :entry_date, :exception_pm, :financials, :industry, :keywords, :lessons_learned, :project_name, :project_owner, :role, :start_date, :status, :summary, :tech
validates_presence_of :business_div, :client, :customer_benifits, :end_date, :exception_pm, :financials, :industry, :keywords, :lessons_learned, :project_name, :project_owner, :role, :start_date, :status, :summary, :tech
def self.search(search_client, search_industry, search_role, search_tech, search_business_div, search_project_owner, search_exception_pm, search_status, search_start_date, search_end_date, search_keywords)
return scoped unless search_client.present? || search_industry.present? || search_role.present? || search_tech.present? || search_business_div.present? || search_project_owner.present? || search_exception_pm.present? || search_status.present? || search_start_date.present? || search_end_date.present? || search_keywords.present?
if search_start_date != ""
search_start_date = Date.parse(search_start_date).strftime("%Y-%m-%d")
end
if search_end_date != ""
search_end_date = Date.parse(search_end_date).strftime("%Y-%m-%d")
end
where(['client LIKE ? AND industry LIKE ? AND role LIKE ? AND tech LIKE ? AND business_div LIKE ? AND project_owner LIKE ? AND exception_pm LIKE ? AND status LIKE ? AND start_date LIKE ? AND end_date LIKE ? AND keywords LIKE ?', "%#{search_client}%", "%#{search_industry}%" , "%#{search_role}%" , "%#{search_tech}%" , "%#{search_business_div}%" , "%#{search_project_owner}%" , "%#{search_exception_pm}%" , "%#{search_status}%", "%#{search_start_date}%", "%#{search_end_date}%","%#{search_keywords}%"])
end
def self.paginated_for_index(projects_per_page, current_page)
paginate(:per_page => projects_per_page, :page => current_page)
end
end
这是我的搜索视图：

这是我的控制器的一部分：
def search
@search = params[:client], params[:industry], params[:role], params[:tech], params[:business_div], params[:project_owner], params[:exception_pm], params[:status], params[:start_date], params[:end_date], params[:keywords]
@project_search = Project.search(*@search).order(sort_column + ' ' + sort_direction).paginated_for_index(per_page, page)
@search_performed = !@search.reject! { |c| c.blank? }.empty?
@project = Project.new(params[:project])
respond_to do |format|
format.html # search.html.erb
format.json { render :json => @project }
end
end
希望有人可以帮助我。我是 Rails 新手，所以轻松一点:)。提前致谢。
