在app的admin目录下创建forms.py文件,用来保存admin蓝图中需要使用到的表单
from flask_wtf import FlaskForm
from wtforms import StringField, PasswordField, SubmitField, FileField, TextAreaField, SelectField, SelectMultipleField
from wtforms.validators import DataRequired, ValidationError, EqualTo
from app.models import Admin, Tag, Auth, Role
tags = Tag.query.all() # 获取数据库中所有的电影标签
auth_list = Auth.query.all() # 获取数据库中所有的权限列表
role_list = Role.query.all() # 获取数据库中所有的角色列表
# 登录表单
class LoginForm(FlaskForm):
"""
管理员登录表单
"""
account = StringField(
label="账号",
validators=[
DataRequired("请输入账号!")
],
description=‘账号‘,
render_kw={
‘class‘: ‘form-control‘,
‘placeholder‘: ‘请输入账号!‘,
‘required‘: ‘required‘
}
)
pwd = PasswordField(
label="密码",
validators=[
DataRequired("请输入密码!")
],
description=‘密码‘,
render_kw={
‘class‘: ‘form-control‘,
‘placeholder‘: ‘请输入密码!‘,
‘required‘: ‘required‘
}

submit = SubmitField(
"登录",
render_kw={

}
)
def validate_account(self, field):
account = field.data
user = Admin.query.filter_by(name=account).count()
if user == 0:
raise ValidationError("账号不存在!请重新输入!!")
在登录视图函数中调用登录表单LoginForm
# 登录
@admin.route(‘/login/‘, methods=[‘GET‘, ‘POST‘])
def login():
form = LoginForm()
if form.validate_on_submit():
data = form.data
admin = Admin.query.filter_by(name=data[‘account‘]).first()
if not admin.check_pwd(data.get("pwd")):
flash("旧密码错误,请重新输入!", "err")
return redirect(url_for("admin.login"))
session[‘admin‘] = data.get("account")
session[‘admin_id‘] = admin.id
adminlog = Adminlog(
admin_id=admin.id,
ip=request.remote_addr
)
db.session.add(adminlog)
db.session.commit()
return redirect(request.args.get("next") or url_for(‘admin.index‘))
return render_template("admin/login.html", form=form)
登录页面中调用后台登录视图函数返回来的变量form
form变量中包含管理员登录需要的字段

退出功能必须要用户登录才能有效,所以要用到登录控制装饰器
@admin.route(‘/logout/‘)
@admin_login_req
def logout():
session.pop("admin", None)
session.pop("admin_id", None)
return redirect(url_for("admin.login"))
后台管理员必须要登录进行密码验证才能打开后台管理页面
,同时用户要用相应的权限才能打开后台管理页面的主页面
所以后台管理主页视图函数必须被登录控制装饰器和权限控制装饰器同时装饰
@admin.route(‘/‘)
@admin_login_req
@admin_auth
def index():
return render_template("admin/index.html")
由于在admin.html页面中已经导入左侧菜单部分,所以后台管理页面主页继承admin.html页面实现顶端部分和左侧菜单栏
{% extends "admin/admin.html" %}

在app的admin目录下的forms.py文件中,定义修改密码的表单

admin = Admin.query.filter_by(name=name).first()
if not admin.check_pwd(pwd):

修改密码必须要登录,所以要用登录控制装饰器装饰修改密码的视图函数
和权限控制装饰器进行管理用户权限判断

在app的admin目录下的forms.py文件中创建TagForm表单,用来保存标签的表单信息

在templates目录下创建ui目录,在ui目录下创建admin_page.html页面,用来保存后台管理页面分页组件代码
