基于flask的微电影管理——后台管理（3）

6.电影评论管理

6.1 直接从用户获取信息，所以不必有forms表单

6.2 用户管理的视图函数

from app import app, db
from flask import render_template, flash, redirect, url_for, request
from app.admin import admin
from app.admin.utils import write_adminlog, is_admin_login, permission_control
from app.models import User, Comment


# ***************************评论管理*****************************
@admin.route("/comment/list/")
@admin.route("/comment/list/<int:page>/")
@is_admin_login
@permission_control
def comment_list(page=1):
    commentsPageObj = Comment.query.paginate(page, per_page=app.config['PER_PAGE'])
    return render_template('admin/comment/list.html', commentsPageObj=commentsPageObj)


@admin.route("/comment/delete/<int:id>/")
@is_admin_login
@permission_control
def comment_del(id=None):
    if id:
        comment = Comment.query.get_or_404(id)
        db.session.delete(comment)
        db.session.commit()
        flash('删除%s用户%s电影评论成功！' % (comment.user.name, comment.movie.name), category='ok')
        write_adminlog('删除%s用户%s电影评论成功！' % (comment.user.name, comment.movie.name))
        return redirect(url_for('admin.comment_list', page=1))

6.3 实现评论管理的页面显示

{% extends 'admin/base.html' %}

{% block title %}评论列表{% endblock %}
{% block content %}
    <div class="col-lg-11">

7.电影收藏管理

7.1 根据用户得知收藏的电影，所以不用forms表单

7.2 电影收藏的视图函数

from app.admin import admin
from app.admin.forms.movie import MovieForm

# ********************************收藏管理***********************

@permission_control
def collect_list(page=1):
    moviecollectsPageObj = MovieCollect.query.paginate(page=page, per_page=app.config['PER_PAGE'])
    return render_template('admin/collect/list.html', moviecollectsPageObj=moviecollectsPageObj, app=app)


@admin.route("/collect/delete/<int:id>")
@is_admin_login
@permission_control
def collect_del(id=None):

        db.session.delete(moviecollect)
        db.session.commit()
        flash('删除%s用户对%s电影收藏成功！' % (moviecollect.user.name, moviecollect.movie.name), category='ok')
        write_adminlog('删除%s用户对%s电影收藏成功')

9.权限管理

9.1 得生成权限列表分发，需要forms表单

from flask_wtf import FlaskForm
from wtforms import StringField, SubmitField
from wtforms.validators import DataRequired


class BaseForm(FlaskForm):
    name = StringField(
        label='权限名称',
        validators=[
            DataRequired('请输入权限名称！')
        ],
    )
    url = StringField(
        label='访问链接',
        validators=[
            DataRequired('请输入访问链接！')
        ],
    )


class AuthForm(BaseForm):
    submit = SubmitField(
        label='添加权限',
    )


class EditAuthForm(BaseForm):
    submit = SubmitField(
        label='更新权限',
    )

11.管理员管理

from wtforms.validators import DataRequired, ValidationError, EqualTo
from flask_wtf import FlaskForm
from wtforms import StringField, SubmitField, PasswordField, SelectField
from wtforms.validators import DataRequired

from app.models import Role


class BaseForm(FlaskForm):
    name = StringField(
        label='管理员名称',
        validators=[
            DataRequired('请输入管理员名称！')
        ],
    )

            DataRequired('请输入管理员密码！')
        ],
    )
    repwd = PasswordField(

        validators=[
            DataRequired('请输入管理员确认密码！'),
            EqualTo('pwd', message='两次密码不一致')

    is_super = SelectField(

        coerce=int,
        choices=[(0, '普通管理员'), (1, '超级管理员')],

    )
    role_id = SelectField(
        label='所属角色',
        validators=[

        ],
        coerce=int,
        # choices=[(role.id, role.name) for role in Role.query.all()],
        description='所属角色',

    )

    def __init__(self, *args, **kwargs):
        super(BaseForm, self).__init__(*args, **kwargs)
        self.role_id.choices = [(v.id, v.name) for v in Role.query.all()]


class AdminForm(BaseForm):
    submit = SubmitField(
        label='添加管理员',
    )


class EditAdminForm(BaseForm):
    submit = SubmitField(
        label='编辑管理员',
    )
