Django - 基数为 10 的 int() 的 Formset 无效文字：''

【中文标题】Django - 基数为 10 的 int() 的 Formset 无效文字：\'\'【英文标题】：Django - Formset invalid literal for int() with base 10: ''Django - 基数为 10 的 int() 的 Formset 无效文字：'' 【发布时间】：2014-01-18 03:41:37 【问题描述】：

我的表单中有一个内联字段，我正在尝试通过 save_formset() 函数访问它

这是我的代码：

def save_formset(self, request, form, formset, change):
    periods = formset.save(commit=False)
    match = periods[0].match
    match_utils = MatchUtils()
    teamstat_utils = TeamStatUtils()
    is_update = match.reported
    match_type = match.tournament.type

    # Find positions
    first_place = match_utils.findPositions(periods,match.blue_team,match.grey_team,match.black_team,1)
    second_place = match_utils.findPositions(periods,match.blue_team,match.grey_team,match.black_team,2)
    third_place = match_utils.findPositions(periods,match.blue_team,match.grey_team,match.black_team,3)

    # Update Match
    match.first_place = first_place
    match.second_place = second_place
    match.third_place = third_place
    match.blue_periods_won = match_utils.findTeamPeriodsWon(periods,'blue_team')
    match.grey_periods_won = match_utils.findTeamPeriodsWon(periods,'grey_team')
    match.black_periods_won = match_utils.findTeamPeriodsWon(periods,'black_team')
    match.reported = True

    # Update team stats
    teamstat_utils.updateTeamStats(match.blue_team,match_utils.findPositionForTeam(match.blue_team,first_place,second_place,third_place),
        match.blue_periods_won,match.grey_periods_won+match.black_periods_won,is_update,match_type) #Blueteam
    teamstat_utils.updateTeamStats(match.grey_team,match_utils.findPositionForTeam(match.grey_team,first_place,second_place,third_place),
        match.grey_periods_won,match.blue_periods_won+match.black_periods_won,is_update,match_type) #Greyteam
    teamstat_utils.updateTeamStats(match.black_team,match_utils.findPositionForTeam(match.black_team,first_place,second_place,third_place),
        match.black_periods_won,match.blue_periods_won+match.grey_periods_won,is_update,match_type) #Blackteam

    pdb.set_trace()
    match.save()
    formset.save()

但我不断收到： int() 以 10 为底的无效文字：''

我不知道为什么，我尝试了 formset.is_valid() 并且它返回 True...

谢谢， 阿拉

【问题讨论】：

请提供异常堆栈跟踪 已编辑！抱歉忘记了！ 【参考方案1】：

您没有发布模型的详细信息。发生这种错误的原因可能是：

    您的模型中声明了 CharField，但您传递的是一个整数 或者，您有一个 IntegerField 和 blank=True，但不要为其提交值。

第二个问题是因为当你声明blank = True 时，Django 将存储并返回一个空字符串。

还有很多可以在这里添加...

发布您的模型可能有助于我们了解究竟是什么问题。

【讨论】：

我刚刚添加了我的模型。谢谢！【参考方案2】：

您需要检查模板中的 URL。您需要将整数 id 传递给 URL user.id，因为 url 需要在模板中具有整数值。

例如。网址：- /polls/user.id/ 希望这对其他人有用。

以上是关于Django - 基数为 10 的 int() 的 Formset 无效文字：''的主要内容，如果未能解决你的问题，请参考以下文章
