django forms
django 中的 form 和 model 的用法很像，都是定义一个类，然后指定一些字段就可以了
最简单的form
from django import forms
class ContactForm(forms.Form):
subject = forms.CharField(max_length=100)
email = forms.EmailField(required=False)
message = forms.CharField(widget=forms.Textarea)
def clean_message(self):
message = self.cleaned_data['message']
num_words = len(message.split())
if num_words < 4:
raise forms.ValidationError("Not enough words!")
return message
def contact(request):
if request.method == 'POST':
form = ContactForm(request.POST)
if form.is_valid():
cd = form.cleaned_data
send_mail(
cd['subject'],
cd['message'],
cd.get('email', 'noreply@example.com'),
['siteowner@example.com'],
)
return HttpResponseRedirect('/contact/thanks/')
else:
form = ContactForm()
return render(request, 'contact_form.html', {'form': form})
<form action="" method="post">
<table>
{{ form.as_table }}
</table>
{% csrf_token %}
<input type="submit" value="Submit">
</form>
| 方法 | 用法 |
|---|---|
| form.str() | return table representation |
| form.as_p() | return p representation |
| form.as_li() | return li representation |
| form.getitem() | return element tag |
| form.init(dict) | fill values |
| form.is_bound | |
| form.is_valid() | |
| form.cleaned_data |
Note not include table/ul/form tags, just the inside tags
ajax
ajax 中如何指定 crsf token
axios 中：
import axios from 'axios';
axios.defaults.xsrfHeaderName = "X-CSRFTOKEN";
axios.defaults.xsrfCookieName = "csrftoken";
settings.py 中
CSRF_COOKIE_NAME = "csrftoken"
