在 Django 中查看错误

Question

我以这种方式使用了 Django 的形式，但出现了错误： 错误：invalid literal for int() with base 10: 'check'

#this is forms.py    
from django import forms

    class PersonalInfo(forms.Form):
        Name = forms.CharField(max_length=20)
        Email_ID = forms.EmailField(required=False)
        Address = forms.CharField(max_length=50,required=False)
        Contact_Phone =  forms.CharField(max_length=20)
        Image = forms.FileField(required=False)

PersonalInfo 在 register.html 中使用

#This is view.py, register calling register.html
    def register(request):
        form = PersonalInfo()
        return render_to_response('register.html', {'form':form}, context_instance=RequestContext(request))

在 register.html 中这是我将使用它的方式：

            {% if form.errors %}
            <p style="color: red;">
                Please correct the error{{ form.errors|pluralize }} below.
            </p>
            {% endif %}

            <form action="/uregister/" method="post">
                <table>
                    {{ form.as_table }}
                </table>
                <input type="submit" value="Submit">
            </form>

这是uregister的观点：

def uregister(request):
    if request.method == 'POST':
    form = PersonalInfo(request.POST)
        if form.is_valid():
            cd = form.cleaned_data
                per_job = Personal(cd['Name'], cd['Email_ID'], cd['Address'], cd['Contact_Phone'], cd['Image'])
                per_job.save()
                return HttpResponseRedirect('/')
        else:
            form = PersonalInfo()
            return render_to_response('register.html', {'form': form}, context_instance=RequestContext(request))

这是 models.py 中的 Personal 模型：

class Personal(models.Model):
    name = models.CharField(max_length=20)
    email = models.EmailField(blank=True,null=True)
    address = models.CharField(max_length=50,blank=True,null=True)
    contact =  models.CharField(max_length=20)
    pic = models.FileField(upload_to='image/',blank=True,null=True)

我得到的错误是：

invalid literal for int() with base 10: 'check'

和

Exception Type: ValueError
Exception Value:    invalid literal for int() with base 10: 'check'
Exception Location: /usr/local/lib/python2.6/dist-packages/django/db/models/fields/__init__.py in get_prep_value, line 479

Check 是我在虚拟数据中给出的名称。 谁能告诉我哪里出错了？请。

Answer 1

我认为问题出在一行

per_job = Personal(cd['Name'], cd['Email_ID'], cd['Address'], cd['Contact_Phone'], cd['Image'])

我不知道是否可以仅使用位置参数创建模型实例，但文档中没有提及。你应该是using keyword parameters:

per_job = Personal(name=cd['Name'], email=cd['Email_ID'], etc.

您看到的错误可能是由于尝试将非整数值分配给具有对象 ID 的默认数据库字段，因此可能是由此引起的。

关于其他的：

• 图像未存储可能是因为您不是正确处理上传文件所需的using form attribute enctype="multipart/form-data"。
• 错误未显示很可能是因为它们在验证后包含在表单中，而您在uregister 视图的else: 分支中将其替换为空实例。
