用Python和SQL Server搭建一个支持筛选、编辑、分页的精灵图鉴网站，具体该怎么一步步实现？

<think>由于问题复杂且涉及多个技术栈，我将分步骤详细说明。注意：完整代码量较大，将按功能模块组织。 # 环境搭建步骤 ## 1. 软件安装 - **Python 3.8+**：官网下载安装 - **SQL Server**：微软官网下载SQL Server 2019 Express（免费版） - **SQL Server Management Studio (SSMS)**：用于数据库管理 - **Python库**：使用pip安装以下库 ```bash pip install flask flask-sqlalchemy pymssql pyodbc openpyxl flask-wtf ``` ## 2. 数据库配置 - 安装SQL Server时选择混合身份验证，设置sa密码 - 使用SSMS登录，创建数据库`SpriteDB` - 创建表`sprites`： ```sql CREATE TABLE sprites ( id INT PRIMARY KEY, name NVARCHAR(100) NOT NULL, status NVARCHAR(50) NOT NULL, -- 获取状态，例如：已获取、未获取 source NVARCHAR(255), -- 获取途径 notes NVARCHAR(500) -- 备注 ); ``` ## 3. 项目结构 ``` SpriteAlbum/ ├── app.py # 主程序 ├── config.py # 配置 ├── models.py # 数据库模型 ├── forms.py # 表单 ├── templates/ │ ├── index.html # 主页面 │ ├── edit.html # 编辑页面 ├── static/ │ ├── css/ # 自定义样式 ``` # 代码实现 ## config.py ```python class Config: SECRET_KEY = 'your-secret-key' SQLALCHEMY_DATABASE_URI = 'mssql+pymssql://sa:your_password@localhost/SpriteDB' SQLALCHEMY_TRACK_MODIFICATIONS = False ``` ## models.py ```python from flask_sqlalchemy import SQLAlchemy db = SQLAlchemy() class Sprite(db.Model): id = db.Column(db.Integer, primary_key=True) name = db.Column(db.String(100), nullable=False) status = db.Column(db.String(50), nullable=False) # 获取状态 source = db.Column(db.String(255)) notes = db.Column(db.String(500)) def __repr__(self): return f"<Sprite(id={self.id}, name='{self.name}')>" ``` ## forms.py ```python from flask_wtf import FlaskForm from wtforms import StringField, SelectField, TextAreaField, SubmitField class FilterForm(FlaskForm): id = StringField('ID') name = StringField('名称') status = SelectField('获取状态', choices=[('', '全部'), ('已获取', '已获取'), ('未获取', '未获取')]) source = StringField('获取途径') submit = SubmitField('筛选') class EditForm(FlaskForm): name = StringField('名称') status = SelectField('获取状态', choices=[('已获取', '已获取'), ('未获取', '未获取')]) source = StringField('获取途径') notes = TextAreaField('备注') submit = SubmitField('保存') ``` ## app.py (主程序) ```python from flask import Flask, render_template, request, redirect, url_for from models import db, Sprite from forms import FilterForm, EditForm from config import Config app = Flask(__name__) app.config.from_object(Config) db.init_app(app) # 创建数据库表（第一次运行时创建） @app.before_first_request def create_tables(): db.create_all() @app.route('/', methods=['GET', 'POST']) def index(): page = request.args.get('page', 1, type=int) per_page = 100 # 每页100条 form = FilterForm(request.args, meta={'csrf': False}) # 构建查询 query = Sprite.query if form.id.data: query = query.filter(Sprite.id == form.id.data) if form.name.data: query = query.filter(Sprite.name.like(f"%{form.name.data}%")) if form.status.data: query = query.filter(Sprite.status == form.status.data) if form.source.data: query = query.filter(Sprite.source.like(f"%{form.source.data}%")) # 计数 total_count = query.count() # 分页 pagination = query.paginate(page=page, per_page=per_page, error_out=False) sprites = pagination.items return render_template('index.html', form=form, sprites=sprites, pagination=pagination, total_count=total_count) @app.route('/edit/<int:id>', methods=['GET', 'POST']) def edit_sprite(id): sprite = Sprite.query.get_or_404(id) form = EditForm(obj=sprite) if form.validate_on_submit(): form.populate_obj(sprite) db.session.commit() return redirect(url_for('index')) return render_template('edit.html', form=form, sprite=sprite) if __name__ == '__main__': app.run(debug=True) ``` ##
