python - Django 模型不会保存

Question

我制作了一个允许用户创建职位列表的表单，我已经声明了模型中的所有字段并创建了模型表单和 View 。通过管理面板向模型添加内容效果很好，并且表单在网站上完美显示。按提交按钮也不会引发错误，但不会保存数据。感谢任何帮助，谢谢!

型号 -

class JobListing(models.Model):

    region_choice = (
        ('1', 'Auckland'),
        ('2', 'Wellington'),
        ('3', 'Christchurch')
    )
    industry_choice = (
        ('1', 'Accounting'),
        ('2', 'Agriculture, fishing & forestry'),
        ('3', 'Automotive'),
        ('4', 'Banking, finance & insurance'),
        ('5', 'Construction & Architecture'),
        ('6', 'Customer service'),
    )
    employment_type_choice = (
        ('1', 'Full Time'),
        ('2', 'Part Time'),
        ('3', 'One-off'),
        ('4', 'Other')
    )

    user = models.OneToOneField(User, unique=True)
    business_name = models.CharField(max_length=50)
    pay_rate = models.FloatField()
    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)
    job_id = models.AutoField("ID", primary_key=True, editable=False, unique=True)

    class Meta:
        verbose_name = 'Job Listing'

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

表格 -

class JobListingForm(forms.ModelForm):

    class Meta:
        model = JobListing
        fields = ['business_name', 'pay_rate', 'employment_type', 'job_description', 'business_address_region',
            'business_address_suburb', 'business_industry']
        widgets = {
            'business_name': forms.TextInput(attrs={'class': 'form-input', 'required': 'true', 'placeholder': 'Name of Business'}),
            'pay_rate': forms.NumberInput(attrs={'class': 'form-input', 'required': 'true', 'placeholder': 'Hourly Rate or One Off Amount'}),

            'job_description': forms.Textarea(attrs={'class': 'form-textarea', 'required': 'true',
                'placeholder': 'Tell us additional information about your job listing e.g. Times, Business Info, Number of positions etc. (2000 Character Limit)'}),
            'business_address_region': forms.Select(attrs={'class': 'form-input', 'required': 'true'}),

Answer 1

您没有在模板中显示任何字段错误。对于每个 {{ form.field }}，您还需要有 {{ form.field.errors }}。

<p> <label for="id_username" class="form-input-label">Business Name</label><br>
    {{ form.business_name }}
    {{ form.business_name.errors }}
<br><p>

这将使您能够看到表单无效的原因。
