Django AttributeError'float'对象没有属性'split'

Question

我安装了模块Django导入/导出link 安装顺利进行。现在，当我想导入与扩展名的文件的.xls它让我看到下面的错误：在

AttributeError的/管理/ XXXX/XXXX/process_import/ “浮动”没有对象属性“分裂”

异常地点： C：\ Python34 \ LIB \站点包\ import_export \ widgets.py干净，线321

当我在这里编辑文件widgets.py源代码

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 
     }) 

这里有行321 ids = filter(None, value.split(self.separator))

Django模型

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) 

Django管理

class VehiculeAdmin(admin.ModelAdmin): 
    list_display = ('matricule', 'modele', 'annee') 
    search_fields = ('matricule', 'modele') 

class Affecter_Vehicule_LigneAdmin(admin.ModelAdmin): 
    list_display = ('vehicule', 'dateAffectation', 'ligne') 

class ArretAdmin(ImportExportModelAdmin): 
    pass 

class Ligne_ArretAdmin(admin.ModelAdmin): 
    list_display = ('ligne', 'arret', 'section', 'sens') 

admin.site.register(Vehicule, VehiculeAdmin) 
admin.site.register(Ligne) 
admin.site.register(Affecter_Vehicule_Ligne, Affecter_Vehicule_LigneAdmin) 
admin.site.register(Arret, ArretAdmin) 
admin.site.register(Ligne_Arret, Ligne_ArretAdmin) 

请帮我解决这个问题？？？

Answer 1

您试图在这一行ids = filter(None, value.split(self.separator))

我想你可以删除这条线拆分浮点值。当你处理None的情况下，之前拆分。
