16.Django提交表单

2024-09-07 01:40:41   216人阅读

Django表单提交一共有三种方式：

1.不使用Django组件进行提交

2.使用django.forms.Form（所有表单类的父类）进行提交

3.使用django.forms.ModelForm（可以和模型绑定的Form）进行提交

 

这里的例子是，给Publisher这个表里添加数据，表结构如下：

class Publisher(models.Model):
    name = models.CharField("名称",max_length=30)
    address = models.CharField("地址", max_length=50)
    city = models.CharField("城市", max_length=60)
    state_province = models.CharField("省份", max_length=30)
    country = models.CharField("国家", max_length=50)
    website = models.URLField("网址")

    class Meta:
        verbose_name = ‘出版商‘
        verbose_name_plural = verbose_name

    def __str__(self):
        return self.name

urls.py里加入如下配置：

url(r‘^add_publisher/$‘, views.add_publisher, name=‘add_publisher‘),

 

一下代码着重介绍模版文件的编写和views.py文件的编写

html文件：\hello_django\hello\templates\add_publisher.html

views.py文件：\hello_django\hello\views.py

1.不使用Django组件进行提交

和普通的html提交没什么不同，后台views.py使用命令一个一个的接収参数，然后进行处理，需要自己进行数据校验，自己进行组装数据

 

html文件：自己写form表单

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>添加出版社信息</title>
</head>
<body>
<form action="{% url ‘add_publisher‘ %}" method="post">
    {% csrf_token %}
    名称:<input name="name" type="text" /><br>
    地址:<input name="address" type="text" /><br>
    城市:<input name="city" type="text" /><br>
    省份:<input name="state_province" type="text" /><br>
    国家:<input name="country" type="text" /><br>
    网址:<input name="website" type="text" /><br>
    <input type="submit" value="http://www.mamicode.com/提交"><br>
</form>
</body>
</html>

views.py（自己接受数据，自己组装数据）

def add_publisher(request):
        if request.method == "POST":
                name = request.POST[‘name‘]
                address = request.POST.get(‘address‘)
                city = request.POST[‘city‘]
                state_province = request.POST[‘state_province‘]
                country = request.POST[‘country‘]
                website = request.POST[‘website‘]
                Publisher.objects.create(
                    name = name,
                    address = address,
                    city = city,
                    state_province = state_province,
                    country = country,
                    website = website,
                )
                return HttpResponse("添加出版社信息成功！")
        else:
                return render(request, ‘add_publisher.html‘, locals())

2.使用django.forms.Form（所有表单类的父类）进行提交

新建\hello_django\hello\forms.py文件，参数是forms.Form标识他是一个Form的子类

from django import forms

class PublisherForm(forms.Form):
    name = forms.CharField(label="名称", error_messages={"required": "必填"})
    address = forms.CharField(label="地址", error_messages={"required": "必填"})
    city = forms.CharField(label="城市", error_messages={"required": "必填"})
    state_province = forms.CharField(label="省份", error_messages={"required": "必填"})
    country = forms.CharField(label="国家", error_messages={"required": "必填"})
    website = forms.URLField(label="网址", error_messages={"required": "必填"})

 

html文件：这样不用自己写表单了

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>添加出版社信息</title>
</head>
<body>
<form action="{% url ‘add_publisher‘ %}" method="post">
    {% csrf_token %}
    {{ publisher_form.as_p }}
    <input type="submit" value="http://www.mamicode.com/提交"><br>
</form>
</body>
</html>

 

views.py文件：不用一个一个接受参数，也不用自己做参数校验了

def add_publisher(request):
    if request.method == "POST":
        publisher_form = PublisherForm(request.POST)
        if publisher_form.is_valid():
            Publisher.objects.create(
                name = publisher_form.cleaned_data[‘name‘],
                address = publisher_form.cleaned_data[‘address‘],
                city = publisher_form.cleaned_data[‘city‘],
                state_province = publisher_form.cleaned_data[‘state_province‘],
                country = publisher_form.cleaned_data[‘country‘],
                website = publisher_form.cleaned_data[‘website‘],
            )
            return HttpResponse("添加出版社信息成功！")
    else:
        publisher_form = PublisherForm()
    return render(request, ‘add_publisher.html‘, locals())

 

3.使用django.forms.ModelForm（可以和模型绑定的Form）进行提交

新建\hello_django\hello\forms.py文件，参数是forms.ModelForm标识他是一个ModelForm的子类

　　from django import forms
　　from hello.models import Publisher

　　class PublisherForm(forms.ModelForm):
   　　 class Meta:
       　　 model = Publisher
      　　  exclude = ("id",)


views.py文件：不用一个一个接受参数，也不用自己做参数校验了，也不同自己创建对象
　　def add_publisher(request):
   　　if request.method == "POST":
      　　publisher_form = PublisherForm(request.POST)
      　　if publisher_form.is_valid():
        　　 publisher_form.save()
         　　return HttpResponse("添加出版社信息成功！")
   　　else:
      　　publisher_form = PublisherForm()
   　　return render(request, ‘add_publisher.html‘, locals())
