Question

我安装了模块Django Import / Export link 安装进展顺利。现在，当我想导入扩展名为.xls的文件时，它会显示以下错误：

/ admin / xxxx / xxxx / process_import /中的AttributeError ＆＃39;浮动＆＃39;没有对象属性＆＃39; split＆＃39;

例外位置： C：\ Python34 \ lib \ site-packages \ import_export \ widgets.py in clean，321行

当我在这里编辑文件widgets.py源代码

时

private void RadioButton1_CheckedChanged(object sender, EventArgs e)
{
    if (RadioButton1.Checked) //If checked == true
    {
        textBox1.Text = "12";
        //example
    }
}

以下是321 def clean(self, value): if not value: return self.model.objects.none() if isinstance(value, float): ids = [int(value)] else: ids = value.split(self.separator) ids = filter(None, value.split(self.separator)) return self.model.objects.filter(**{ '%s__in' % self.field: ids })

行

Django模型

ids = filter(None, value.split(self.separator))

Django admin

class Vehicule(models.Model):
    matricule = models.CharField(max_length=200)
    modele = models.CharField(max_length=200)
    annee = models.IntegerField()

    def __str__(self):
        return self.matricule

class Ligne(models.Model):
    nom = models.CharField(max_length=200)
    vehicule = models.ManyToManyField(Vehicule, through='Affecter_Vehicule_Ligne')

    def __str__(self):
        return str(self.nom)

class Affecter_Vehicule_Ligne(models.Model):
    vehicule = models.ForeignKey(Vehicule, on_delete=models.CASCADE)
    ligne = models.ForeignKey(Ligne, on_delete=models.CASCADE)
    actif = models.BooleanField(default=False)
    dateAffectation = models.DateTimeField(null=True)

    def __str__(self):
        return str(self.dateAffectation)


class Arret(models.Model):
   nom = models.CharField(max_length=200, null=True)
   latitude = models.CharField(max_length=200, null=True)
   longitude = models.CharField(max_length=200, null=True)
   lignes = models.ManyToManyField(Ligne, through='Ligne_Arret')

   def __str__(self):
       return str(self.nom)

class Ligne_Arret(models.Model):
    sens = models.CharField(max_length=200)
    section = models.BooleanField(default=False)
    ligne = models.ForeignKey(Ligne, on_delete=models.CASCADE)
    arret = models.ForeignKey(Arret, on_delete=models.CASCADE)

    def __str__(self):
        return str(self.arret)

请帮我解决这个问题???

Answer 1

您正尝试在此行AddParameter(SQLCommand, "@IsUser", SqlDbType.Bit, ParameterDirection.Input, obj.IsUser)

中拆分浮点值

我想你可以删除这一行。当您处理ids = filter(None, value.split(self.separator))案例并在之前拆分时。

Django AttributeError＆＃39; float＆＃39;对象没有属性＆＃39; split＆＃39;
