我制作了一个体育预测应用程序，应该可以让人们跟踪他们的数学预测。
到目前为止HTML有48场比赛，他们必须填写每场比赛的分数，但是当我尝试保存分数时，这个错误不断出现：
invalid literal for int() with base 10: ''
以下是我的观点：
@login_required(login_url="/")
def inicio(request):
if request.method == "POST":
form = Pronosticos(request.POST)
for i in range(48):
pronostico, _ = PartidosUsuarios.objects.get_or_create(idUsuario=request.user, idPartido=request.POST.get("idPartido"+str(i), ""), PaisL=request.POST.get("PaisL"+str(i), ""), Local=request.POST.get("Local"+str(i), ""), Visita=request.POST.get("Visita"+str(i), ""), PaisV=request.POST.get("PaisV"+str(i), ""), Capturado="Si")
if pronostico.Local > pronostico.Visita:
pronostico.Resultado = "Local"
pronostico.save()
elif pronostico.Visita > pronostico.Local:
pronostico.Resultado = "Visita"
pronostico.save()
elif pronostico.Local == pronostico.Visita:
pronostico.Resultado = "Empate"
pronostico.save()
return render(request, "brasil/inicio.html")
partidos_fifa = PartidosFifa.objects.order_by("Partido")[:64]
context = {"partidos_fifa": partidos_fifa}
return render(request, "brasil/inicio.html", context)
forms.py
class Pronosticos(ModelForm):
class Meta:
model = PartidosUsuarios
fields = ["idPartido", "PaisL", "Local", "Visita", "PaisV"]
models.py
class PartidosUsuarios(models.Model):
idUsuario = models.OneToOneField(User)
idPartido = models.CharField(max_length=20)
PaisL = models.CharField(max_length=250)
Local = models.IntegerField(max_length=11, default=0)
Visita = models.IntegerField(max_length=11, default=0)
PaisV = models.CharField(max_length=250)
Resultado = models.CharField(max_length=250)
Puntos = models.IntegerField(max_length=11, default=0)
Capturado = models.CharField(max_length=10, default="No")
def __unicode__(self):
return unicode(self.idPartido)
最后是表单和输入的html示例：
<tr>
<input type="hidden" value="1" name="idPartido1" id="idPartido"/>
<td><input value="Brasil" class="pronosticos" name="PaisL1" id="PaisL"/></td>
<td><input name="Local1" id="Local"/></td>
<td>-</td>
<td><input name="Visita1" id="Visita"/></td>
<td><input value="Croacia" class="pronosticos" name="PaisV1" id="PaisV"/></td>
</tr>
<tr>
<input type="hidden" value="2" name="idPartido2" id="idPartido"/>
<td><input value="México" class="pronosticos" name="PaisL2" id="PaisL"/></td>
<td><input name="Local2" id="Local"/></td>
<td>-</td>
<td><input name="Visita2" id="Visita"/></td>
<td><input value="Camerún" class="pronosticos" name="PaisV2" id="PaisV"/></td>
</tr>
似乎它抱怨视图中的行以＆＃34; pronostico开头，_ =＆＃34;
非常感谢任何帮助。

答案 0 :(得分：0)
出现错误是因为你正试图存储一个空字符串''是一个整数字段。
使用前检查表单值。
