Django的Form主要具有一下几大功能：
生成HTML标签验证用户数据（显示错误信息）HTML Form提交保留上次提交数据初始化页面显示内容1、form的创建：
示例：
class LoginForm(Form): # 正则验证：不能为空，6-18 username=fields.CharField( max_length=18, min_length=6, required=True, error_messages={ 'required':'用户名不能为空', 'min_length':'用户名最少需要6个字符', 'max_length':'用户名最多可用18个字符', }) # 正则验证: 不能为空，16+ password = fields.CharField( min_length=10, required=True, error_messages={ 'required': '密码不能为空', 'min_length': '密码最少需要10个字符', } )在views.py函数内部的处理：
from django.shortcuts import render,HttpResponse,redirect from django.forms import Form from django.forms import fields class LoginForm(Form): # 正则验证：不能为空，6-18 username=fields.CharField( max_length=18, min_length=6, required=True, error_messages={ 'required':'用户名不能为空', 'min_length':'用户名最少需要6个字符', 'max_length':'用户名最多可用18个字符', }) # 正则验证: 不能为空，16+ password = fields.CharField( min_length=10, required=True, error_messages={ 'required': '密码不能为空', 'min_length': '密码最少需要10个字符', } ) def login(request): if request.method == "GET": return render(request,'login.html') else: obj = LoginForm(request.POST) if obj.is_valid(): # 用户输入格式正确 print(obj.cleaned_data) # 字典类型 return redirect('http://www.cnblogs.com/xuyuanyuan123/') else: # 用户输入格式错误 return render(request,'login.html',{'obj':obj})url.py
from app01 import views urlpatterns = [ url(r'^admin/', admin.site.urls), url(r'^login.html$', views.login), ]login.html
<!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <title>Title</title> <link rel="stylesheet" href="/static/plugins/bootstrap-3.3.7-dist/css/bootstrap.css" /> <link rel="stylesheet" href="/static/plugins/font-awesome-4.7.0/css/font-awesome.css" /> <style> body { background: url("http://p1.so.qhimgs1.com/bdr/_240_/t01496c13d1b5e3b8e1.gif"); background-size: 100%; } .login{ width: 550px; height: 360px; background-color: papayawhip; text-align: center; margin-top: 20px; margin-left: 510px; position: fixed; } .user{ margin-top: 100px; font-size: 20px; } .pwd{ margin-top: 30px; font-size: 20px; } .choise{ margin-top: 20px; } </style> </head> <h1 style="text-align: center;font-size: 50px;font-style:normal;color:#b2dba1;margin-top: 170px">博客园</h1> <body> <form id="f1" method="post" action="/login.html" class="form-horizontal"> <div class="login"> {% csrf_token %} <div class="user"> 用户名：<input type="text" name="username">{{ obj.errors.username.0 }} </div> <div class="pwd"> 密 码：<input type="password" name="password">{{ obj.errors.password.0 }} </div> <div> <button type="submit" class="btn btn-primary">登录</button> <a class="btn btn-primary" οnclick="Ajaxlogin()">Ajax登录</a> <a class="btn btn-primary" href="/register.html">注册</a> </div> {{ msg }} </div> </form> <script src="/static/jquery-1.12.4.js"></script> </body> </html> View Code执行的效果图是：
2、form类
创建Form类时，主要涉及到 【字段】 和 【插件】
字段：用于对用户请求数据的验证
插件：用于自动生成HTML;
（1）、Django内置字段如下：
Field required=True, 是否允许为空 widget=None, HTML插件 label=None, 用于生成Label标签或显示内容 initial=None, 初始值 help_text='', 帮助信息(在标签旁边显示) error_messages=None, 错误信息 {'required': '不能为空', 'invalid': '格式错误'} show_hidden_initial=False, 是否在当前插件后面再加一个隐藏的且具有默认值的插件（可用于检验两次输入是否一直） validators=[], 自定义验证规则 localize=False, 是否支持本地化 disabled=False, 是否可以编辑 label_suffix=None Label内容后缀示例：
class TestForm(forms.Form): user = fields.CharField( required=True, max_length=12, min_length=3, error_messages={}, widget = widgets.TextInput(attrs={"class":123}), # 定制html插件，属性：用attrs参数 # widget= widgets.Textarea() label="姓名", initial='laiying', show_hidden_initial=False, # validators=[] #自定制验证规则 # disabled=True label_suffix=":" )Django内置字段如下：
CharField(Field) max_length=None, 最大长度 min_length=None, 最小长度 strip=True 是否移除用户输入空白 IntegerField(Field) max_value=None, 最大值 min_value=None, 最小值 FloatField(IntegerField) ... DecimalField(IntegerField) max_value=None, 最大值 min_value=None, 最小值 max_digits=None, 总长度 decimal_places=None, 小数位长度 BaseTemporalField(Field) input_formats=None 时间格式化 DateField(BaseTemporalField) 格式：2015-09-01 TimeField(BaseTemporalField) 格式：11:12 DateTimeField(BaseTemporalField)格式：2015-09-01 11:12 DurationField(Field) 时间间隔：%d %H:%M:%S.%f ... RegexField(CharField) regex, 自定制正则表达式 max_length=None, 最大长度 min_length=None, 最小长度 error_message=None, 忽略，错误信息使用 error_messages={'invalid': '...'} EmailField(CharField) ... FileField(Field) allow_empty_file=False 是否允许空文件 ImageField(FileField) ... 注：需要PIL模块，pip3 install Pillow 以上两个字典使用时，需要注意两点： - form表单中 enctype="multipart/form-data" - view函数中 obj = MyForm(request.POST, request.FILES) URLField(Field) ... BooleanField(Field) ... NullBooleanField(BooleanField) ... ChoiceField(Field) ... choices=(), 选项，如：choices = ((0,'上海'),(1,'北京'),) required=True, 是否必填 widget=None, 插件，默认select插件 label=None, Label内容 initial=None, 初始值 help_text='', 帮助提示 ModelChoiceField(ChoiceField) ... django.forms.models.ModelChoiceField queryset, # 查询数据库中的数据 empty_label="---------", # 默认空显示内容 to_field_name=None, # HTML中value的值对应的字段 limit_choices_to=None # ModelForm中对queryset二次筛选 ModelMultipleChoiceField(ModelChoiceField) ... django.forms.models.ModelMultipleChoiceField TypedChoiceField(ChoiceField) coerce = lambda val: val 对选中的值进行一次转换 empty_value= '' 空值的默认值 MultipleChoiceField(ChoiceField) ... TypedMultipleChoiceField(MultipleChoiceField) coerce = lambda val: val 对选中的每一个值进行一次转换 empty_value= '' 空值的默认值 ComboField(Field) fields=() 使用多个验证，如下：即验证最大长度20，又验证邮箱格式 fields.ComboField(fields=[fields.CharField(max_length=20), fields.EmailField(),]) MultiValueField(Field) PS: 抽象类，子类中可以实现聚合多个字典去匹配一个值，要配合MultiWidget使用 SplitDateTimeField(MultiValueField) input_date_formats=None, 格式列表：['%Y--%m--%d', '%m%d/%Y', '%m/%d/%y'] input_time_formats=None 格式列表：['%H:%M:%S', '%H:%M:%S.%f', '%H:%M'] FilePathField(ChoiceField) 文件选项，目录下文件显示在页面中 path, 文件夹路径 match=None, 正则匹配 recursive=False, 递归下面的文件夹 allow_files=True, 允许文件 allow_folders=False, 允许文件夹 required=True, widget=None, label=None, initial=None, help_text='' GenericIPAddressField protocol='both', both,ipv4,ipv6支持的IP格式 unpack_ipv4=False 解析ipv4地址，如果是::ffff:192.0.2.1时候，可解析为192.0.2.1， PS：protocol必须为both才能启用 SlugField(CharField) 数字，字母，下划线，减号（连字符） ... UUIDField(CharField) uuid类型需求： 在页面上不用加self直接显示input框
代码如下：
text.html
<body> {{txt}}</body>
views.py
def test(request): if request.methon == 'GET': txt = "<input type='text' />" from django.utils.safestring import mark_safe txt = mark_safe(txt) return render(request,'text.html',{'txt':txt})注：UUID是根据MAC以及当前时间等创建的不重复的随机字符串
>>> import uuid # make a UUID based on the host ID and current time >>> uuid.uuid1() # doctest: +SKIP UUID('a8098c1a-f86e-11da-bd1a-00112444be1e') # make a UUID using an MD5 hash of a namespace UUID and a name >>> uuid.uuid3(uuid.NAMESPACE_DNS, 'python.org') UUID('6fa459ea-ee8a-3ca4-894e-db77e160355e') # make a random UUID >>> uuid.uuid4() # doctest: +SKIP UUID('16fd2706-8baf-433b-82eb-8c7fada847da') # make a UUID using a SHA-1 hash of a namespace UUID and a name >>> uuid.uuid5(uuid.NAMESPACE_DNS, 'python.org') UUID('886313e1-3b8a-5372-9b90-0c9aee199e5d') # make a UUID from a string of hex digits (braces and hyphens ignored) >>> x = uuid.UUID('{00010203-0405-0607-0809-0a0b0c0d0e0f}') # convert a UUID to a string of hex digits in standard form >>> str(x) '00010203-0405-0607-0809-0a0b0c0d0e0f' # get the raw 16 bytes of the UUID >>> x.bytes b'\x00\x01\x02\x03\x04\x05\x06\x07\x08\t\n\x0b\x0c\r\x0e\x0f' # make a UUID from a 16-byte string >>> uuid.UUID(bytes=x.bytes) UUID('00010203-0405-0607-0809-0a0b0c0d0e0f') View Code（2）、Django内置插件：
TextInput(Input) NumberInput(TextInput) EmailInput(TextInput) URLInput(TextInput) PasswordInput(TextInput) HiddenInput(TextInput) Textarea(Widget) DateInput(DateTimeBaseInput) DateTimeInput(DateTimeBaseInput) TimeInput(DateTimeBaseInput) CheckboxInput Select NullBooleanSelect SelectMultiple RadioSelect CheckboxSelectMultiple FileInput ClearableFileInput MultipleHiddenInput SplitDateTimeWidget SplitHiddenDateTimeWidget SelectDateWidget View Code常用选择插件
<strong># 单radio，值为字符串</strong> # user = fields.CharField( # initial=2, # widget=widgets.RadioSelect(choices=((1,'上海'),(2,'北京'),)) # ) <strong># 单radio，值为字符串</strong> # user = fields.ChoiceField( # choices=((1, '上海'), (2, '北京'),), # initial=2, # widget=widgets.RadioSelect # ) <strong># 单select，值为字符串</strong> # user = fields.CharField( # initial=2, # widget=widgets.Select(choices=((1,'上海'),(2,'北京'),)) # ) <strong># 单select，值为字符串</strong> # user = fields.ChoiceField( # choices=((1, '上海'), (2, '北京'),), # initial=2, # widget=widgets.Select # ) <strong># 多选select，值为列表</strong> # user = fields.MultipleChoiceField( # choices=((1,'上海'),(2,'北京'),), # initial=[1,], # widget=widgets.SelectMultiple # ) <strong># 单checkbox</strong> # user = fields.CharField( # widget=widgets.CheckboxInput() # ) <strong># 多选checkbox,值为列表</strong> # user = fields.MultipleChoiceField( # initial=[2, ], # choices=((1, '上海'), (2, '北京'),), # widget=widgets.CheckboxSelectMultiple # )示例：
select的多种写法：
a、单选
# 下拉框的方法1： # cls_id = fields.IntegerField( # widget=widgets.Select(choices=[(1,'上海'),(2,'北京')])) # 下拉框的方法2： # cls_id = fields.CharField( # widget=widgets.Select(choices=[(1,'昌平区'),(2,'海淀区'),(3,'朝阳区')])) # 下拉框的方法3： # cls_id = fields.ChoiceField( # choices=[(1,'10号线'),(2,'8号线'),(3,'5号线')] # )b、多选
#多选下拉框（有自定义属性） # xdb = fields.MultipleChoiceField( # choices=[(1, '朝阳区'), (2, '海淀区'), (3, '昌平区')], # widget=widgets.SelectMultiple(attrs={'class':'c1'}) #后面参数是定制属性 # ) #单选checkbox # xdb = fields.CharField( # widget=widgets.CheckboxInput() # ) #多选checkbox （多个checkbox,二选一） # xdb = fields.MultipleChoiceField( # initial=[2, ], # choices=((1, '上海'), (2, '北京'),), # widget=widgets.CheckboxSelectMultiple # ) #多个选项Radio （互斥 三选一） # xdb = fields.ChoiceField( # choices=((1, '上海'), (2, '北京'),(3, '北京1'),), # initial=2, # widget=widgets.RadioSelect # )
用form实现验证的功能：（一对一、一对多、多对多）
1、单表的操作：（一对一）====>班级表
首先建立一个新的目录：（该结构如下）
首先先建立表格，在models.py内写入：
from django.db import models class Classes(models.Model): cname=models.CharField(max_length=32) class Student(models.Model): sname=models.CharField(max_length=32) email=models.CharField(max_length=32) age=models.IntegerField(max_length=16) cls=models.ForeignKey('Classes') class Teacher(models.Model): tname=models.CharField(max_length=32) c2t=models.ManyToManyField('Classes') # c2t=models.ManyToManyField('Classes')相当于建立的第四张关系表urls.py
from django.conf.urls import url from django.contrib import admin from app01 import views urlpatterns = [ url(r'^admin/', admin.site.urls), # =======班级表:单表操作===== url(r'^classes.html$',views.classes), url(r'^add_class.html$',views.add_class), url(r'^edit_class/(\d+)',views.edit_class), url(r'^del_class/(\d+)',views.del_class), # ======班级表和学生表操作：一对多操作===== url(r'^student.html$',views.student), url(r'^add_student.html$',views.add_student), url(r'^edit_student/(\d+)',views.edit_student), url(r'^del_student/(\d+)',views.del_student), # ===========班级表和老师表操作：多对多操作========= url(r'^teacher.html$',views.teacher), url(r'^add_teacher.html$',views.add_teacher), url(r'^edit_teacher/(\d+)',views.edit_teacher), url(r'^del_teacher/(\d+)',views.del_teacher), ]views.py
