django 使用django-bootstrap4插件时，使表单呈2列或其他列分布时的写法

前言

django 使用django-bootstrap4插件时，使表单呈2列或其他列分布时的写法。
在django-bootstrap4中没有内置的方法设置表单内容成几列分布，这里采用bootstrap4的栅格布局实现效果

具体操作

• forms.py

  class RegisterForm(UserCreationForm):
  username = CustomCharField(label="Username", help_text="Only letters can be entered!<br> For login.",widget=forms.TextInput(attrs={"id":"register_username","autocomplete":"new-username"}))
  password1 = CustomCharField(label="Password",widget=forms.PasswordInput(attrs={'autocomplete': 'new-password',"id":"register_password"}),help_text=password_validation.password_validators_help_text_html(),)
  password2 = CustomCharField(label="Password confirmation",widget=forms.PasswordInput(attrs={'autocomplete': 'new-password'}),help_text=("Enter the same password as before, for verification."),)
  first_name = CustomCharField(label="First name")
  last_name = CustomCharField(label="Last name")
  email = CustomCharField(label="Email",widget=forms.EmailInput())
  
  gender = CustomCharField(label="Gender", widget=forms.Select(choices=(("N","--"),("W","Women"),("M","Man"))))
  contact_number = CustomCharField(label="Contact Number", widget=forms.TextInput())
  address = CustomCharField(label="Address", widget=forms.TextInput())
  
  class Meta:
  	model = User
  	fields = ("username","first_name","last_name", "gender","password1", "password2","contact_number","email","address")
  
  def save(self, commit=True):
  	user = super(UserCreationForm, self).save(commit=False)
  
  	user.set_password(self.cleaned_data['password1'])
  
  	if commit:
  		user.save()
  
  		client_obj = models.Client(**{"user": user,
  									  "gender": self.data["gender"],
  									  "contact_number": self.data["contact_number"],
  									  "address": self.data["address"]
  									  })
  		client_obj.save()
  	return user
  

• views.py传给template

• index.html

  <form method="post" action="{% url 'register' %}">
  	<div class="row row-cols-2 row-cols-md-2">
  		{% csrf_token %}
  		{% bootstrap_form register_form %}
  	</div>
  	<div class="modal-footer">
  		<button type="button" class="btn btn-secondary" data-dismiss="modal">Close</button>
  		<button type="button" class="btn btn-primary" onclick="SubmitRegister()">Register
  		</button>
  	</div>
  </form>
  <-javascript-!>
  <script>
  	$(".form-group").addClass("col-6")
  </script>
