传入HTML模板中：
2 新建用户
2.1 原始方式理思路：不会采用（本质）【麻烦】
{% extends 'layout.html' %}
{% block content %}
<div class="container">
<div class="panel panel-default">
<div class="panel-heading">
<h3 class="panel-title"> <span style="font-weight:bold;">新建用户</span> </h3>
</div>
<div class="panel-body">
<form method="post">
{% csrf_token %}
<div class="form-group">
<labe><span style="font-weight:bold;">姓名</span></labe>
<input type="text" class="form-control" placeholder="姓名"/>
</div>
<div class="form-group">
<labe><span style="font-weight:bold;">密码</span></labe>
<input type="text" class="form-control" placeholder="密码"/>
</div>
<div class="form-group">
<labe><span style="font-weight:bold;">年龄</span></labe>
<input type="text" class="form-control" placeholder="年龄"/>
</div>
<div class="form-group">
<labe><span style="font-weight:bold;">余额</span></labe>
<input type="text" class="form-control" placeholder="余额"/>
</div>
<div class="form-group">
<labe><span style="font-weight:bold;">入职时间</span></labe>
<input type="text" class="form-control" placeholder="入职时间"/>
</div>
<div class="form-group">
<labe><span style="font-weight:bold;">性别</span></labe>
<select class="form-control">
{% for item in gender_choices %}
<option value="{{ item.0 }}">{{ item.1 }}</option>
{% endfor %}
</select>
</div>
<div class="form-group">
<labe><span style="font-weight:bold;">部门</span></labe>
<select class="form-control">
{% for item in depart_list %}
<option value="{{ item.id }}">{{ item.title }}</option>
{% endfor %}
</select>
</div>
<button type="submit" class="btn btn-primary">提交</button>
</form>
</div>
</div>
</div>
{% endblock %}
提交：
- 定义name属性
- GET请求POST提交，添加到数据库中，返回到用户列表页面
2.2 Django组件
- Form组件（小简便）
- ModelForm组件（最简便）
2.2.1 初识Form
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})
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>
2.2.2 ModelForm（推荐）
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)
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})
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>
