django Form表单模块实例

Posted 2020-09-24

定义forms表单：

from django import forms

class ContactForm(forms.Form):
    subject = forms.CharField(max_length=100)
    message = forms.CharField(widget=forms.Textarea)
    sender = forms.EmailField()
    cc_myself = forms.BooleanField(required=False)

定义views视图：

from django.core.mail import send_mail

if form.is_valid():
    subject = form.cleaned_data[‘subject‘]
    message = form.cleaned_data[‘message‘]
    sender = form.cleaned_data[‘sender‘]
    cc_myself = form.cleaned_data["cc_myself"]
    
    recipients = [‘[email protected]‘]
    if cc_myself:
        recipients.append(sender)
    
    send_mail(subject,message,sender,recipients)
    return HttpResponseRedirect(‘/thanks/‘)

创建表单模板文件：

<p><label for=‘id_subject‘>Subject:</label>
   <input id="id_subject" type="text" name="subject" maxlength="100" /></p>
<p><label for=‘id_message‘>Message:</label>
   <input id="id_message" type="text" name="message" /></p>
<p><label for=‘id_sender‘>Sender:</label>
   <input id="id_sender" type="email" name="sender" " /></p>
<p><label for=‘id_cc_myself‘>Cc_myself:</label>
   <input id="id_cc_myself" type="checkbox" name="id_cc_myself" /></p>

当然,在模板里面也是可以手工渲染字段

{{ form.non_field_errors }}
<div class="fieldWrapper">
    {{ form.subject.errors }}
    <label for="{{ form.subject.id_for_label }}">Email subject:</label>
    {{ form.subject }}
</div>
<div class="fieldWrapper">
    {{ form.message.errors }}
    <label for="{{ form.message.id_for_label }}">Your message:</label>
    {{ form.message }}
</div>
<div class="fieldWrapper">
    {{ form.sender.errors }}
    <label for="{{ form.sender.id_for_label }}">Your email address:</label>
    {{ form.sender }}
</div>
<div class="fieldWrapper">
    {{ form.cc_myself.errors }}
    <label for="{{ form.cc_myself.id_for_label }}">CC yourself?:</label>
    {{ form.cc_myself }}
</div>
