我正在创建简单的web app，它显示了按类别划分的产品。 在这个项目的开始，我创建了一个页面的简单视图，然后我连接我的网页与数据库。。。 现在，当我编辑“add.html”页面的CSS文件时，没有任何变化。 我删除了CSS文件的整个代码，增加了一个样式。 我改变了字体大小。
当我运行应用程序-代码贝娄-我得到了旧的风格。 我多次检查CSS样式表a的链接路径。 此外，我尝试重启我的电脑，如果有一些错误从我的一边。 我错过了什么，我不知道是什么。
我将非常感谢你的帮助！
注意:每个页面（HTML文件）都有自己的CSS文件。 现在他们都是一样的（旧风格）
我的工作目录-“克隆”
clone
--> __pycache__
--> static
--> admin # contains only admin view pages
--> add # page folder
--> style.css # style for "add" page
--> images # contains images on the page
--> image.jpg
--> ...
--> public # contains the same file/folder system as "admin"
--> templates
--> admin
--> _base_admin.html # parent's page
--> add.html # child's page
--> ... # other html files
--> public
--> goods.db # database file
--> run.py # flask script
“添加”页面的Python代码
@app.route("/pridat/", methods=["GET", "POST"])
def add():
if "admin" in session:
if request.method == "POST":
name = request.form["name"]
price = request.form["price"]
image = request.files["image"]
tag = request.form["tag"]
# Set absolute path, where the image will be saved
path = f"S:/Python/Projects/Flask/clone/static/admin/products/{tag}/images/{image.filename}"
image.save(path)
# Edit path to realative - allow to load image from wd (working directory)
path = f"/static/admin/products/{tag}/images/{image.filename}"
new_product = Product(name=name, price=price, image_path=path, tag=tag)
db.session.add(new_product)
db.session.commit()
flash("Successfully uploaded!")
print(f"Successfully uploaded")
return redirect(url_for(tag))
