我应该如何使用不同大小的列分页？

Question

我想在rails web app中实现以下功能：

在我的图片中，1 = @ article.first，2 = @ article.offset（1）.first

例如：

from xmlsoccer import XmlSoccer
from straightred.models import StraightredFixtureLive
    @csrf_exempt
    def updatefixtureslive(request, soccerseason, league):

        if request.user.is_authenticated():

            xmlsoccer = XmlSoccer(api_key='XYZ123ABC789', use_demo=False)
            fixtureslive = xmlsoccer.call_api(method='GetLiveScoreByLeague',
                                       league='English Premier League')

        count = 0

            for fixturelive in fixtureslive:



                if 'Id' in fixturelive.keys():

                count = count + 1       
                    fixtureLiveUpdate = StraightredFixtureLive(fixtureid_id=fixturelive['Id'],
                                                           away_team_id = fixturelive['AwayTeam_Id'],
                                                           home_team_id = fixturelive['HomeTeam_Id'],
                                                           fixturedate = fixturelive['Date'],
                                                           fixturestatus = fixturelive['Time'],
                                                           fixturematchday_id = fixturelive['Round'],
                                                           spectators = fixturelive['Spectators'],
                                                           hometeamscore = fixturelive['HomeGoals'],
                                                           awayteamscore = fixturelive['AwayGoals'],
                                                           homegoaldetails = fixturelive['HomeGoalDetails'],
                                                           awaygoaldetails = fixturelive['AwayGoalDetails'],
                                                           hometeamyellowcarddetails = fixturelive['HomeTeamYellowCardDetails'],
                                                           awayteamyellowcarddetails = fixturelive['AwayTeamYellowCardDetails'],
                                                           hometeamredcarddetails = fixturelive['HomeTeamRedCardDetails'],
                                                           awayteamredcarddetails = fixturelive['AwayTeamRedCardDetails']
                                )
                    fixtureLiveUpdate.save()

            return HttpResponse("Live games have been updated." + str(count))
        else:
            return HttpResponse("You must be logged in to update teams.")

现在我应该如何在视图中实现此布局？

will_paginate（或任何分页）的使用（或不使用）与您如何放置视觉元素无关 - 这是MVC架构的全部要点。

对paginate的调用可确保您一次获得一页16个结果，页面编号由您的?page=参数控制。

元素通常是一个接一个地布局，这导致使用.each：

形成

@articles.each do |article|
  render 'articles/article', :article => article
end

在您的情况下，您可能需要逐个访问集合中的文章，甚至索引。 ActiveRecord::Relation个集合支持类似数组的访问，因此要获取16个元素中的第一个，您可以使用articles[0]，第二个位于articles[1]，一直到{16} articles[15] }。
