传入HTML模板中：

新建用户：

• 原始方式理思路：不会采用（本质）【麻烦】

• Django组件

  • Form组件（小简便）
  • ModelForm组件（最简便）

1.1 初识Form

1.1.1 views.py

class MyForm(Form):
    user = forms.CharField(widget=forms.Input)
    pwd = form.CharFiled(widget=forms.Input)
    email = form.CharFiled(widget=forms.Input)
    account = form.CharFiled(widget=forms.Input)
    create_time = form.CharFiled(widget=forms.Input)
    depart = form.CharFiled(widget=forms.Input)
    gender = form.CharFiled(widget=forms.Input)


def user_add(request):
    if request.method == "GET":
        form = MyForm()
        return render(request, 'user_add.html',{"form":form})

1.2.2 user_add.html

<form method="post">
    {% for field in form%}
    	{{ field }}
    {% endfor %}
    <!-- <input type="text"  placeholder="姓名" name="user" /> -->
</form>

<form method="post">
    {{ form.user }}
    {{ form.pwd }}
    {{ form.email }}
    <!-- <input type="text"  placeholder="姓名" name="user" /> -->
</form>

1.2 ModelForm（推荐）

1.2.1 models.py

class UserInfo(models.Model):
    """ 员工表 """
    name = models.CharField(verbose_name="姓名", max_length=16)
    password = models.CharField(verbose_name="密码", max_length=64)
    age = models.IntegerField(verbose_name="年龄")
    account = models.DecimalField(verbose_name="账户余额", max_digits=10, decimal_places=2, default=0)
    create_time = models.DateTimeField(verbose_name="入职时间")
    depart = models.ForeignKey(to="Department", to_field="id", on_delete=models.CASCADE)
    gender_choices = (
        (1, "男"),
        (2, "女"),
    )
    gender = models.SmallIntegerField(verbose_name="性别", choices=gender_choices)

1.2.2 views.py

class MyForm(ModelForm):
    xx = form.CharField*("...")
    class Meta:
        model = UserInfo
        fields = ["name","password","age","xx"]


def user_add(request):
    if request.method == "GET":
        form = MyForm()
        return render(request, 'user_add.html',{"form":form})

1.2.3 user_add.html

<form method="post">
    {% for field in form%}
    	{{ field }}
    {% endfor %}
    <!-- <input type="text"  placeholder="姓名" name="user" /> -->
</form>

<form method="post">
    {{ form.user }}
    {{ form.pwd }}
    {{ form.email }}
    <!-- <input type="text"  placeholder="姓名" name="user" /> -->
</form>
