user_edit的html页面和user_model_form_add.html的页面一样
1.手动在数据库中添加三行数据
insert into app01_userinfo(name,password,age,account,create_time,gender,depart_id)
VALUES("小明","123",23,100.87,"2020-11-11",4,1),
("小王","123",23,100.87,"2020-11-11",4,1),
("小红","123",23,100.87,"2020-11-11",4,1);
2.用户列表的创建
views
def user_list(request):
""" 用户管理 """
# 获取所有用户列表 [obj,obj,obj]
queryset = models.UserInfo.objects.all()
"""
# 用Python的语法获取数据
for obj in queryset:
print(obj.id, obj.name, obj.account, obj.create_time.strftime("%Y-%m-%d"), obj.gender, obj.get_gender_display(), obj.depart_id, obj.depart.title)
# print(obj.name, obj.depart_id)
# obj.depart_id # 获取数据库中存储的那个字段值
# obj.depart.title # 根据id自动去关联的表中获取哪一行数据depart对象。
"""
return render(request, 'user_list.html', {"queryset": queryset})
html
{% extends 'layout.html' %}
{% block content %}
<div class="container">
<div style="margin-bottom: 10px">
<a class="btn btn-success" href="/depart/add/">
{# target="_blank"在新页面跳转打开#}
<span class="glyphicon glyphicon-plus-sign" aria-hidden="true"></span>
新建用户
</a>
</div>
<div class="bs-example" data-example-id="panel-without-body-with-table">
<div class="panel panel-default">
<div class="panel-heading">
<span class="glyphicon glyphicon-th-list" aria-hidden="true"></span>
用户列表
</div>
<table class="table table-bordered">
<thead>
<tr>
<th>ID</th>
<th>姓名</th>
<th>密码</th>
<th>年龄</th>
<th>余额</th>
<th>时间</th>
<th>性别</th>
<th>部门</th>
<th>操作</th>
</tr>
</thead>
<tbody>
{% for obj in queryset %}
<tr>
<th>{{ obj.id }}</th>
<td>{{ obj.name }} <td>
<td>{{ obj.password }} <td>
<td>{{ obj.age }} <td>
<td>{{ obj.account }} <td>
<td>{{ obj.create_time|date:"Y-m-d H:i:s" }} <td>
{# 模板语法不能用（）会自动补充 #}
<td>{{ obj.get_gender_display }} <td>
<td>{{ obj.depart.title }} <td>
<td>
<a class="btn btn-primary btn-xs" href="#">编辑</a>
<a class="btn btn-danger btn-xs" href="#">删除</a>
<td>
</tr>
{% endfor %}
</tbody>
</table>
</div>
</div>
</div>
{% endblock %}
3.新建用户
原始方法新建用户
views
def user_add(request):
'''添加用户'''
if request.method == "GET":
context = {
'gender_choices': models.UserInfo.gender_choices,
"depart_list": models.Department.objects.all()
}
return render(request, 'user_add.html', context)
# 获取用户提交的数据
name = request.POST.get('name')
pwd = request.POST.get('pwd')
age = request.POST.get('age')
account = request.POST.get('ac')
ctime = request.POST.get('ctime')
gender = request.POST.get('gd')
depart_id = request.POST.get('dp')
# 添加到数据库中
models.UserInfo.objects.create(name=name, password=pwd, age=age,
account=account, create_time=ctime,
gender=gender, depart_id=depart_id)
# 返回到用户列表页面
return redirect("/user/list/")
html
{% extends 'layout.html' %}
{% block content %}
<div class="container">
<div class="panel panel-default">
<div class="panel-heading">
新建用户
</div>
<div class="panel-body">
<form method="post">
{% csrf_token %}
<div class="form-group">
<label>姓名</label>
<input type="text" class="form-control" placeholder="姓名" name="name"/>
</div>
<div class="form-group">
<label>密码</label>
<input type="text" class="form-control" placeholder="密码" name="pwd"/>
</div>
<div class="form-group">
<label>年龄</label>
<input type="text" class="form-control" placeholder="年龄" name="age"/>
</div>
<div class="form-group">
<label>余额</label>
<input type="text" class="form-control" placeholder="余额" name="ac"/>
</div>
<div class="form-group">
<label>入职时间</label>
<input type="text" class="form-control" placeholder="入职时间" name="ctime"/>
</div>
<div class="form-group">
<label>性别</label>
<select class="form-control" name="gd">
{% for item in gender_choices %}
<option value="{{ item.0 }}">{{ item.1 }}</option>
{% endfor %}
</select>
</div>
<div class="form-group">
<label>部门</label>
<select class="form-control" name="dp">
{% 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 %}
原始方法思路不被采用的太麻烦了
1.用户提交数据没有校验
2.错误页面上应有错误提示
3.页面上每一个字段都需要重新写一遍
4.关联的数据还要手动获取，循环展示在页面当中
4.初始form
views
class MyForm(Form):
user = forms.CharField(widget=forms.Input)
pwd = forms.CharField(widget=forms.Input)
email = forms.CharField(widget=forms.Input)
def user_add(request):
if(request.method == "GET"):
form = MyForm()
return render(request, 'user_add.html',{'form':form})
2user_add.html
<form method='post'>
{% for field in form%}
{{ field }}
{% endfor %}
</form>
<form method='post'>
{{ form.user }}
{{ form.pwd }}
{{ form.email }}
<!-- <input type="text" class="form-control" placeholder="姓名" name="name"/> -->
</form>
5.ModleForm(推荐)
views
class UserModelForm(forms.ModelForm):
class Meta:
model = models.UserInfo
fields = ['name', 'password', 'age', 'account', 'create_time', 'gender', 'depart']
def __init__(self,*args, **kwargs):
super().__init__(*args, **kwargs)
# 循环找到所有的插件，添加class="form-control"
for name,field in self.fields.items():
field.widget.attrs = {"class": "form-control","placeholder":field.label}
def user_model_form_add(request):
'''添加用户基于ModelForm版本'''
form = UserModelForm()
return render(request,'user_model_form_add.html',{'form':form})
user_model_form_add.html
{% extends 'layout.html' %}
{% block content %}
<div class="container">
<div class="panel panel-default">
<div class="panel-heading">
新建用户
</div>
<div class="panel-body">
<form method="post">
{% csrf_token %}
{% for field in form %}
<div class="form-group">
<label>{{ field.label }}</label>
{{ field }}
<!-- <input type="text" class="form-control" placeholder="姓名" name="name"/>-->
</div>
{% endfor %}
<button type="submit" class="btn btn-primary">提交</button>
</form>
</div>
</div>
</div>
{% endblock %}
6.添加错误提示
views
def user_model_form_add(request):
'''添加用户基于ModelForm版本'''
if request.method =="GET":
form = UserModelForm()
return render(request,'user_model_form_add.html',{'form':form})
form = UserModelForm(data=request.POST)
# 调用form.is_valid()拿着data=request.POST的数据，对field的数据进行注意校验
if form.is_valid():
# 校验成功获取数据
# print(form.cleaned_data)
# 如果数据合法保存数据自动存到models.UserInfo类中
form.save()
return redirect('/user/list/')
# 校验失败获取错误信息form.errors
# print(form.errors)
# 校验错误（在页面上显示错误）
return render(request, 'user_model_form_add.html', {'form': form})
对user_model_form_add.html进行修改
{# novalidate不让浏览器进行自动校验#}
<form method="post" novalidate>
{% csrf_token %}
{% for field in form %}
<div class="form-group">
<label>{{ field.label }}</label>
{{ field }}
{# 获取第一个错误的信息#}
<span style="color: red">{{ field.errors.0 }}</span>
<!-- <input type="text" class="form-control" placeholder="姓名" name="name"/>-->
</div>
{% endfor %}
<button type="submit" class="btn btn-primary">提交</button>
</form>
在settins.py中
将报错改成中文
# LANGUAGE_CODE = 'en-us' LANGUAGE_CODE = 'zh-hans'
用户编辑页面
user_edit的views.py
def user_edit(request,nid):
'''编辑用户'''
# 根据id去数据库获取要编辑的哪一行的数据对象放在外面get和post都能用到
row_object = models.UserInfo.objects.filter(id=nid).first()
if request.method =="GET":
form = UserModelForm(instance=row_object)
return render(request, 'user_edit.html', {'form': form})
#在提交的时候不再新增数据，而是吧新提交的数据更新到原来的上面
form = UserModelForm(data=request.POST,instance=row_object)
if form.is_valid():
form.save()
return redirect('/user/list/')
return render(request, 'user_edit.html', {'form': form})
user_edit的html页面和user_model_form_add.html的页面一样
删除页面
def user_delete(request, nid):
models.UserInfo.objects.filter(id=nid).delete()
return redirect('/user/list/')
<a class="btn btn-danger btn-xs" href="/user/{{ obj.id }}/delete/">删除</a>
