标签：报错信息 compile pwd 密码字段 保留 lis title isp body
我们之前在HTML页面中利用form表单向后端提交数据时,都会写一些获取用户输入的标签并且用form标签把他们包起来.
同时我们在好多场景下都需要对用户进行校验,比如校验用户是否输入,输入的长度和格式等正不正确,如果用户输入的内容有错误就需要在页面上相应的位置显示对相应的错误信息
总结:
生成页面可用的HTML标签
对用户提交的数据进行校验
保留上次输入内容Views.py
def register(request):
error = ''
if request.method=='POST':
uname=request.POST.get('uname')
pwd=request.POST.get('pwd')
#对注册进行校验
if len(uname)<6:
error='用户长度不能小于6位'
else:
#将用户名和密码写入数据库中
user_obj=models.User.objects.create(
unme=uname,
pwd = pwd
)
user_obj.save()
return HttpResponse('注册成功')
return render(request, "register.html", {"error_msg": error_msg})
先定义好一个RegForm类:
from django import forms
#按照Django form组件的要求写一个类
class RegForm(forms.Form):
name=forms.CharField(label='用户名')#form字段的名称写的是什么,那么前端input标签的时候,name属性的值就是什么
pwd=forms.CharField(label='密码')
#再写一个视图函数
def register2(request):
form_obj=RegForm() #实例化
if request.method == 'POST':
#实例化form对象的时候,把post提交过来的数据直接传进去
form_obj=RegForm(data=request.POST) #既然传过来的input标签的name属性值和form类对应的字段名一样的,所以接过来后,form就取出对应的form字段名相同的数据进行form校验
#调用form_obj校验数据的方法
if form_obj.is_valid():
return HttpResponse("注册成功")
return render(request, "register2.html", {"form_obj": form_obj})
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>注册2</title>
</head>
<body>
<form action="/reg2/" method="post" novalidate autocomplete="off"> #novalidate 告诉前端form表单，不要对输入的内容做校验
{% csrf_token %}
#{{ form_obj.as_p }} 直接写个这个，下面的用户名和密码的标签不自己写，你看看效果
<div>
<label for="{{ form_obj.name.id_for_label }}">{{ form_obj.name.label }}</label>
{{ form_obj.name }} {{ form_obj.name.errors.0 }} #errors是这个字段所有的错误，我就用其中一个错误提示就可以了，再错了再提示，并且不是给你生成ul标签了，单纯的是错误文本
{{ form_obj.errors }} #这是全局的所有错误，找对应字段的错误，就要form_obj.字段名
</div>
<div>
<label for="{{ form_obj.pwd.id_for_label }}">{{ form_obj.pwd.label }}</label>
{{ form_obj.pwd }} {{ form_obj.pwd.errors.0 }}
</div>
<div>
<input type="submit" class="btn btn-success" value="注册">
</div>
</form>
</body>
</html>创建Form类时,主要涉及到 [字段] 和 [插件],字段用于用户请求数据的验证,插件用于自动生成HTML
初始值,input框里的初始值
class LoginForm(forms.Form):
username = forms.CharField(
min_length=8,
label="用户名",
initial="张三" # 设置默认值
)
pwd = forms.CharField(
min_length=6,
label="密码")重写错误信息
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"
}
)
pwd = forms.CharField(min_length=6, label="密码")class LoginForm(forms.Form):
...
pwd = forms.CharField(
min_length=6,
label="密码",
widget=forms.widgets.PasswordInput(attrs={'class': 'c1'}, render_value=True) #这个密码字段和其他字段不一样，默认在前端输入数据错误的时候，点击提交之后，默认是不保存的原来数据的，但是可以通过这个render_value=True让这个字段在前端保留用户输入的数据
)单radio值为字符串
class LoginForm(forms.Form):
username = forms.CharField( #其他选择框或者输入框，基本都是在这个CharField的基础上通过插件来搞的
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"
}
)
pwd = forms.CharField(min_length=6, label="密码")
gender = forms.fields.ChoiceField(
choices=((1, "男"), (2, "女"), (3, "保密")),
label="性别",
initial=3, #初始值
widget=forms.widgets.RadioSelect()
)class LoginForm(forms.Form):
...
hobby = forms.fields.ChoiceField( #注意，单选框用的是ChoiceField，并且里面的插件是Select，不然验证的时候会报错， Select a valid choice的错误。

label="爱好",
initial=3,
widget=forms.widgets.Select()
)class LoginForm(forms.Form):
...
hobby = forms.fields.MultipleChoiceField( #多选框的时候用MultipleChoiceField，并且里面的插件用的是SelectMultiple，不然验证的时候会报错。
choices=((1, "篮球"), (2, "足球"), (3, "双色球"), ),
label="爱好",
initial=[1, 3],
widget=forms.widgets.SelectMultiple()
)class LoginForm(forms.Form):
...
keep = forms.fields.ChoiceField(

)#单选的checkbox
class TestForm2(forms.Form):

choices=(
('True',1),
('False',0),
),
label="是否7天内自动登录",
initial="1",
widget=forms.widgets.CheckboxInput(),
)
选中:'True' #form只是帮我们做校验,校验选择内容的时候,就是看在没在我们的choices里面,里面有这个值,表示合法,没有就不合法
没选中:'False'
---保存到数据库里面 keep:'True'
if keep == 'True':
session 设置有效期7天
else:
passclass LoginForm(forms.Form):
...
hobby = forms.fields.MultipleChoiceField(
choices=((1, "篮球"), (2, "足球"), (3, "双色球"),),
label="爱好",
initial=[1, 3],
widget=forms.widgets.CheckboxSelectMultiple()
)from django import forms
from django.forms import widgets
class BookForm(forms.Form):
date = forms.DateField(widget=widgets.TextInput(attrs={'type':'date'})) #必须指定type，不然不能渲染成选择时间的input框
在使用选择标签时，需要注意choices的选项可以配置从数据库中获取，但是由于是静态字段 获取的值无法实时更新，需要重写构造方法从而实现choice实时更新。
from django.forms import Form
from django.forms import widgets
from django.forms import fields
class MyForm(Form):
user = fields.ChoiceField(
#choices=((1, '上海'), (2, '北京'),),
initial=2,
widget=widgets.Select
)
def __init__(self, *args, **kwargs):
super(MyForm,self).__init__(*args, **kwargs) #注意重写init方法的时候，*args和**kwargs一定要给人家写上，不然会出问题，并且验证总是不能通过，还不显示报错信息
# self.fields['user'].choices = ((1, '上海'), (2, '北京'),)
# 或
self.fields['user'].choices = models.Classes.objects.all().values_list('id','caption')

email = fields.EmailField(required=False,
error_messages={'required': u'邮箱不能为空','invalid': u'邮箱格式错误'},
widget=widgets.TextInput(attrs={'class': "form-control", 'placeholder': u'邮箱'}))我们在Form类中定义clean_字段名()方法,就能够实现对特有的字段进行校验
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"
},
widget=forms.widgets.TextInput(attrs={"class": "form-control"})
)
...
# 定义局部钩子，用来校验username字段,之前的校验股则还在，给你提供了一个添加一些校验功能的钩子
def clean_username(self):
value = self.cleaned_data.get("username")
if "666" in value:
raise ValidationError("光喊666是不行的")
else:
return value? 我们在Form类中定义clean()方法,就能实现对字段进行全局校验,字段全部验证完,局部钩子也全部执行后,执行这个局部钩子校验.
class LoginForm(forms.Form):
...
password = forms.CharField(
min_length=6,
label="密码",
widget=forms.widgets.PasswordInput(attrs={'class': 'form-control'}, render_value=True)
)
re_password = forms.CharField(
min_length=6,
label="确认密码",
widget=forms.widgets.PasswordInput(attrs={'class': 'form-control'}, render_value=True)
)
...
# 定义全局的钩子，用来校验密码和确认密码字段是否相同，执行全局钩子的时候，cleaned_data里面肯定是有了通过前面验证的所有数据
def clean(self):
password_value = self.cleaned_data.get('password')
re_password_value = self.cleaned_data.get('re_password')
if password_value == re_password_value:
return self.cleaned_data #全局钩子要返回所有的数据
else:
self.add_error('re_password', '两次密码不一致') #在re_password这个字段的错误列表中加上一个错误，并且clean_data里面会自动清除这个re_password的值，所以打印clean_data的时候会看不到它
raise ValidationError('两次密码不一致')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 iterms(self.fields):
self.fields[field].widget.attrs.update({
'class': 'form-control'
})别忘了在settings.py中配置静态文件
STATIC_URL = '/static/'
STATICFILES_DIRS = [
os.path.join(BASE_DIR,'statics'),
