我可以链接到不是flask中模板文件夹的html文件吗

Question

*我正在尝试制作flask，动态生成指向每个“1.index.html”的链接（*存在于中的是“项目文件夹”，它本身位于“项目”文件夹）

*链接必须是项目文件夹的名称，并指向其中的“1.index.html”

*我已经做了所有事情，一切正常，唯一的问题是flask不允许链接到templates文件夹中不存在的html文件，因此当我单击链接时，会出现错误

jinja2.exceptions.TemplateNotFound: projects\0 . market\1 . index.html

这是文件夹的结构&；文件：

/flask-app
   app.py
   /templates
      0 . base.html
      1 . index.html
      2 . home.html
      3 . about.html
      4 . contact.html
      6 . projects.html
      /Projects
         /0 . market
            1 . index.html
            ..other files...
         /1 . chat
            1 . index.html
            ..other files...
         /2 . stocks
            1 . index.html
            ..other files...
 ..other files...

这是app.py文件

    from flask import Flask, request, render_template

    projects_names = os.listdir(projects_folder_path)
    projects_names_list = []        # all projects folders names are here
    for project_name in projects_names:

        c += 1
        x += 1
        project_path = f"E:\\Mbarki\\My Projects\\Web development\\0 . Flask-Projects-Manager\\templates\\projects\\{project_name.real_name}"
        project_files_names = os.listdir(project_path)
        for project_file_name in project_files_names:

                break
    
    return render_template("5 . projects.html", all_projects_final_form = all_projects_final_form)


@app.route("/projects/<link>")                                     # THE PROBLEM IS HERE
def routes(link):                                                  # THE PROBLEM IS HERE
    return render_template(f'projects\\{link}\\1 . index.html ')   # THE PROBLEM IS HERE



if __name__ == "__main__":
    app.run(debug=True)

这是“6.projects.html”文件：

[{% extends '0 . base.html' %}


{% block title %}

{% block content %}
<div class="content">

        </thead>

            {% for project in all_projects_final_form %}

以下是“6.projects.html”文件的图像：

当我点击其中一个链接时，这里是我得到的错误图像：

jinja2.exceptions.TemplateNotFound: projects\0 . market\1 . index.html

提醒：此代码中的所有内容都正常，并且运行良好，唯一的问题是我无法链接不在templates目录中的html文件

Answer 1

我在自己的子目录项目中也做了类似的事情，我的工作类似于以下内容：

&13； 第13部分,；

return render_template('projects/' + link + '/1 . index.html')

；

和#13；
