问题描述
现在我的POST方法有问题，未写入数据库且未显示在管理站点中.
I now have an issue with my POST Method not writing to the database and not showing in Admin site.
views.py文件将一直工作到到达'if form.is_valid()'为止，但除此之外没有更多.我究竟做错了什么?请帮忙，我花了很多时间来寻找答案，但无济于事.
the views.py file works until it gets to the 'if form.is_valid()' but doesn't go any further than that. What am I doing wrong? Please help, I've spent time trying to search for the answer but to no avail.
代码如下
urls.py
path('weekly/', user_views.weekly, name='weekly'),
views.py
def weekly(request):
if request.method == 'POST':
form = SubscriptionForm(request.POST)
print('I got this far 3!')
if form.is_valid():
form.save()
messages.success(request, 'Thank you for your payment!')
return redirect('classes')
else:
return render(request, 'clubex/weekly.html', {'title': '1 Week Free'})
else:
return render(request, 'clubex/weekly.html', {'title': '1 Week Free'})
models.py(这些名称是否必须与HTML文档中的"id"相匹配?)
models.py (do these names have to match the 'id' in the HTML doc?)
class Subscription(models.Model):
firstName = models.CharField(max_length=100)
lastName = models.CharField(max_length=100)
username = models.CharField(max_length=100)
sub_type = models.CharField(max_length=50)
email = models.EmailField(max_length=100)
address = models.CharField(max_length=100)
address2 = models.CharField(max_length=100)
state = models.CharField(max_length=100)
country = models.CharField(max_length=100)
zip = models.CharField(max_length=10)
same_address = models.BooleanField()
save_info = models.BooleanField()
credit = models.BooleanField()
debit = models.BooleanField()
paypal = models.BooleanField()
cc_name = models.CharField(max_length=100)
cc_number = models.CharField(max_length=20)
cc_expiration = models.CharField(max_length=10)
cc_cvv = models.IntegerField()
def __str__(self):
return f'{self.firstName} {self.lastName} {self.sub_type}'
forms.py(这些名称必须与HTML文档中的"id"相匹配吗?)
forms.py (do these names have to match the 'id' in the HTML doc?)
class SubscriptionForm(forms.ModelForm):
class Meta:
model = Subscription
fields = [

推荐答案
该表单无效.使用sub_type和state，您传递的是 choicefield ，而模型需要的是 charfield
The form is not valid. With sub_type and state, you are passing a choicefield and the model needs a charfield
您的表单必须为:
class SubscriptionForm(forms.ModelForm):
firstName = forms.CharField(
required=True,
label="First Name",
widget=forms.TextInput( attrs = {
'type':"text",
'placeholder':"First name",
'class':'form-control', # html input class
})
)
sub_type = forms.ChoiceField(
required=True,
label="Subscription Type",
choices= (
('Option 1', 'Choose'),
('Option 2', 'Weekly $ Free'),
...
),
widget=forms.Select( attrs = {
'class':'your-css-class'
})
)
...
将表单传递到您的html
pass the form to your html
def weekly_get(request):
form = SubscriptionForm()
return render('weekly.html',{'form':form })
然后，您的html
<form method="post" action="/weekly/" class="needs-validation">
{% csrf_token %}
{% for field in form %}
<div class="row">
<div class="col-md-6 mb-3">
{{field.label_tag}}
{{field}}
</div>
</div>
{% endfor %}
</form>
