Question

我的网站上有一个列表系统，目前正在创建一个页面，允许用户编辑他们的列表，我已经完成了大部分工作，但是我仍然坚持保存更新的表单。目前，如果他们保存已编辑的表单而不是更新模型，则会创建一个全新的列表条目，并且仍然保留旧的列表条目。如果有人可以请看我的代码那么好，我已经坚持这个问题很久了！

@login_required(redirect_field_name='login')
def editlisting(request, pk):

    post = JobListing.objects.get(pk=pk)

    if str(request.user) != str(post.user):
        return redirect("index")

    if request.method == "POST":
        print("test")
        form = JobListingForm(request.POST, instance=post, force_update=True)

        if form.is_valid():
            form.save()
            return redirect('index')

    else:
        print("else")
        form = JobListingForm(instance=post)

    context = {
        "form": form
    }

    return render(request, "editlisting.html", context)

模型 -

class JobListing(models.Model):

    region_choice = (
        ('Auckland', 'Auckland'),
        ('Wellington', 'Wellington'),
        ('Christchurch', 'Christchurch')
    )
    industry_choice = (
        ('Accounting', 'Accounting'),
        ('Agriculture, fishing & forestry', 'Agriculture, fishing & forestry'),
        ('Automotive', 'Automotive'),
        ('Banking, finance & insurance', 'Banking, finance & insurance'),

        ('Part Time', 'Part Time'),
        ('One-off', 'One-off'),
        ('Other', 'Other')
    )

    user = models.CharField(max_length=50)
    job_title = models.CharField(max_length=30)
    pay_rate = models.DecimalField(max_digits=10, decimal_places=2)
    employment_type = models.CharField(max_length=10, choices=employment_type_choice)
    job_description = models.CharField(max_length=2000)
    business_address_region = models.CharField(max_length=50, choices=region_choice)
    business_address_suburb = models.CharField(max_length=50)
    business_industry = models.CharField(max_length=50, choices=industry_choice)
    email = models.EmailField(max_length=50, blank=True, null="True")
    telephone = models.IntegerField(blank=True, null='True')
    active_listing = models.BooleanField(default=True)

    class Meta:
        verbose_name = 'Job Listing'

    def clean(self):
        if not (self.email or self.telephone):
            raise ValidationError("You must specify either email or telephone")
        if not self.email:
            self.email = "Not Provided"

    def __unicode__(self):
        return "%s" % self.job_title

我的注册应用程序中可能会影响它的一段代码？

def signup(self, request, user):
    SignUpProfile.objects.create(
        user=user,
        account_type=self.cleaned_data['account_type'],
        contact_number=self.cleaned_data['contact_number']
    )

表格 -

class JobListingForm(forms.ModelForm):

    class Meta:
        model = JobListing
        fields = ['job_title', 'pay_rate', 'employment_type', 'job_description', 'business_address_region',
            'business_address_suburb', 'business_industry', 'telephone', 'email']
        widgets = {
            'job_title': forms.TextInput(attrs={'class': 'form-input', 'placeholder': 'Job Title'}),
            'pay_rate': forms.NumberInput(attrs={'class': 'form-input', 'placeholder': 'Hourly Rate or One Off Amount'}),

Answer 1

您的表单action错误。将其更改为：

<form action="{% url 'editlisting' %}" class="createjoblisting" id="createjoblisting_form" method="post" >

在您复制了创建模板后，您的表单会将您的数据发布到创建商家信息的视图，而不是对其进行编辑。

编辑列表表单是重复
