Django之Form应用Bootstrap样式

应用Bootstrap样式示例：

<!DOCTYPE html>
<html lang="en">
<head>
  <meta charset="UTF-8">
  <meta http-equiv="x-ua-compatible" content="IE=edge">
  <meta name="viewport" content="width=device-width, initial-scale=1">
  <link rel="stylesheet" href="/static/bootstrap/css/bootstrap.min.css">
  <title>login</title>
</head>
<body>
<div class="container">
  <div class="row">
    <form action="/login2/" method="post" novalidate class="form-horizontal">
      {% csrf_token %}
      <div class="form-group">
        <label for="{{ form_obj.username.id_for_label }}"
               class="col-md-2 control-label">{{ form_obj.username.label }}</label>
        <div class="col-md-10">
          {{ form_obj.username }}
          <span class="help-block">{{ form_obj.username.errors.0 }}</span>
        </div>
      </div>
      <div class="form-group">
        <label for="{{ form_obj.pwd.id_for_label }}" class="col-md-2 control-label">{{ form_obj.pwd.label }}</label>
        <div class="col-md-10">
          {{ form_obj.pwd }}
          <span class="help-block">{{ form_obj.pwd.errors.0 }}</span>
        </div>
      </div>
      <div class="form-group">
      <label class="col-md-2 control-label">{{ form_obj.gender.label }}</label>
        <div class="col-md-10">
          <div class="radio">
            {% for radio in form_obj.gender %}
              <label for="{{ radio.id_for_label }}">
                {{ radio.tag }}{{ radio.choice_label }}
              </label>
            {% endfor %}
          </div>
        </div>
      </div>
      <div class="form-group">
        <div class="col-md-offset-2 col-md-10">
          <button type="submit" class="btn btn-default">注册</button>
        </div>
      </div>
    </form>
  </div>
</div>

<script src="/static/jquery-3.2.1.min.js"></script>
<script src="/static/bootstrap/js/bootstrap.min.js"></script>
</body>
</html>

批量添加样式可通过重写form类的init方法来实现

class LoginForm(forms.Form):
    username = forms.CharField(
        min_length=8,
        label="用户名",
        initial="张三",
        error_messages={
            "required": "不能为空",
            "invalid": "格式错误",
            "min_length": "用户名最短8位"
        }
    ...

    def __init__(self, *args, **kwargs):
        super(LoginForm, self).__init__(*args, **kwargs)
        for field in iter(self.fields):
            self.fields[field].widget.attrs.update({
                'class': 'form-control'
            })

views.py如book表的添加和数据展示

from django.shortcuts import render,HttpResponse,redirect
from app01 import models
from django import forms
# Create your views here.

class BookForm(forms.Form):
    title = forms.CharField(
        max_length=16,
        label='书名:',
        initial='zhang',
        # widget = forms.widgets.PasswordInput(attrs={'class': 'form-control'},render_value=True),
        widget = forms.widgets.TextInput(attrs={'class': 'form-control'},),

    )
    # title2 = forms.CharField(
    #     max_length=16,
    #     label='书名:',
    #     initial='zhang',
    #     # widget = forms.widgets.PasswordInput(attrs={'class': 'form-control'},render_value=True),
    #     widget=forms.widgets.TextInput(attrs={'class': 'form-control'}, ),
    #
    # )
    sex = forms.ChoiceField(
        choices=(
            ('1','男'),
            ('2','女'),
        )
        ,
        label='性别:',
        # widget=forms.widgets.RadioSelect(),
        # widget=forms.widgets.RadioSelect(),
        # widget=forms.widgets.SelectMultiple(attrs={'class':'form-control'}),
        widget=forms.widgets.Select(attrs={'class':'form-control'}),
        # widget=forms.widgets.CheckboxInput(),
        # widget=forms.widgets.CheckboxSelectMultiple(),
    )
    publishDate = forms.DateField(
        label='出版日期:',
        widget=forms.widgets.TextInput(attrs={'type':'date','class':'form-control'}),
    )
    price=forms.DecimalField(
        max_digits=5,
        decimal_places=2,
        label='书籍的价格:',
        widget=forms.widgets.NumberInput(attrs={'class': 'form-control'}
    ))

    # publish = forms.ModelChoiceField(
    #     label='出版社:',
    #     queryset=models.Publish.objects.all(),
    #     widget=forms.widgets.Select(attrs={'class': 'form-control'}
    # ))
    publish_id = forms.ChoiceField(
        label='出版社:',
        widget=forms.widgets.Select(attrs={'class': 'form-control'}
    ))
    authors = forms.ModelMultipleChoiceField(

        queryset=models.Author.objects.all(),
        widget = forms.widgets.SelectMultiple(attrs={'class': 'form-control'}
    ))

    def __init__(self,*args, **kwargs):
        super().__init__(*args, **kwargs)
        self.fields['publish_id'].choices = models.Publish.objects.values_list('pk','name')


def index(request):
    if request.method == 'GET':
        form_obj = BookForm()

        return render(request,'index.html',{'form_obj':form_obj})

    else:
        print(request.POST)
        form_obj = BookForm(request.POST)
        print(form_obj.is_valid())
        print(form_obj.errors)
        if form_obj.is_valid():
            print(form_obj.cleaned_data)
            authors_obj = form_obj.cleaned_data.pop('authors')
            new_book_obj = models.Book.objects.create(**form_obj.cleaned_data)
            new_book_obj.authors.add(*authors_obj)
            return redirect('show')

        else:
            print(form_obj.errors)
            return render(request,'index.html',{'form_obj':form_obj})


def show(request):

    book_objs = models.Book.objects.all()

    return render(request,'show.html',{'book_objs':book_objs})

def edit_book(request,n):


    return HttpResponse('欢迎来到编辑页面')


def delete_book(request,n):
    return HttpResponse('欢迎来到删除页面')
