以10为底的int（）无效文字：“收件箱”

Question

此表单由通用视图更新：

models.py：

class CustomUser(User):
   user_bio = models.TextField(blank=True, null=True)
   birth_date = models.DateField(null=True, blank=True)
   def __str__(self):
           return self.username

class SafeTransaction(models.Model):
    trans_recipient = models.ForeignKey(CustomUser, on_delete = models.CASCADE,related_name = 'trans_Recipient',null = True)
    trans_recipient_email = models.CharField(max_length = 1000, blank=True, null=True)
    trans_sender = models.ForeignKey(CustomUser, on_delete = models.CASCADE,related_name = 'safe_Transactions', null = True)
    date = models.DateTimeField(auto_now_add=True, blank=True)
    subject = models.CharField(max_length = 1000, blank = True)
    #trans_type = models.CharField(choices=(1,'Buildingwork'))#DROPDOWN BOX
    trans_unread = models.BooleanField(default = True)
    arbitrator_name = models.CharField(max_length=1000,blank=True, null=True)
    payment_condition = models.TextField(blank=True, null=True)
    amount_to_pay = models.DecimalField(blank=True, null=True, max_digits=50, decimal_places=2)
    is_finalised = models.BooleanField(default=False)

views.py：

class SafeTransUpdateView(UpdateView):
'''
    This view lets the user Update a SafeTransaction receipt
'''
form_class = SafeTransactionForm
model = SafeTransaction
template_name = "myInbox/safeTrans_update.html"

forms.py：

class SafeTransactionForm(forms.ModelForm):
''' SafeTranSactionForm '''
#version one of trans recipient
trans_recipient = forms.ModelChoiceField(queryset=CustomUser.objects.all(), widget=forms.TextInput())

#version two of trans_recipient
#trans_recipient = forms.CharField(widget=forms.TextInput(attrs={'class':'special'}))

def clean_trans_recipient(self):
    data = self.cleaned_data['trans_recipient']
    try:
        return CustomUser.objects.get(username=data)
    except CustomUser.DoesNotExist:
        raise forms.ValidationError("No user with this username exists")

class Meta:
    model = SafeTransaction
    fields = [  'trans_recipient',
                'trans_recipient_email',
                'subject',
                'arbitrator_name',
                'payment_condition',
                'amount_to_pay']

所以在表单中，我主要是试图从ChoiceField继承TextInput小部件。实际提交带有此版本的表格后： trans_recipient = forms.ModelChoiceField(queryset=CustomUser.objects.all(), widget=forms.TextInput())，我被告知输入的选项无效。

对于第二个版本：trans_recipient = forms.CharField(widget=forms.TextInput(attrs={'class':'special'}))，在提交此表格时，第一个错误是：

之后，该项目实际上已更新！

我尝试了几种方法，但是由于它们似乎是最可行的，所以坚持使用这两种方法。我认为将trans_recipients保留为Django为ForeignKey model属性提供的默认下拉字段是没有意义的，因为它在庞大的用户群中很快会变得很笨拙。

我想知道一种方便的方法来使用TextInput小部件进行搜索，并在数据库中查询键入的术语，在这种情况下，请使用通用的UpdateView类更新Item。
