再问：Flask-Bootstrap怎么了？

Question

好的

所以你不喜欢我上一个问题

这是第二个问题，包含的信息比实际需要的多得多。在 flask-bootstrap 模块中定义基本目录是一个非常简单的问题。如果你设法看到我的last question，我展示了我的代码，但这里还有一些你出于某种奇怪原因想要的无用信息：

Index.html

{% extends 'bootstrap/base.html' %}
<!-- TEST THINGS ON A DIFFERENT REPL! -->


<!DOCTYPE html>
<html>
  <head>

    <!-- This is for the tab -->
    <title>Helliott-chip</title>
    <meta charset="utf-8">
    <meta name="viewport" content="width=device-width">
    <link href="{{ url_for('static', filename='style.css') }}" rel="stylesheet" type="text/css" />

  </head>
  <body>
    <!-- Title on top -->
    <h1><center>Helliot-Chip</center></h1>
    <p>New User? <a href="{{ url_for('register') }}">Click to Register!</a></p>

    <!-- Grey Menu Select -->
    <div class="scrollmenu1">
      {% if current_user.is_anonymous %}
      <a href="{{ url_for('login') }}">Login</a>
      {% else %}
      <a href="{{ url_for('logout') }}">Logout</a>
      <a href="{{ url_for('user', username=current_user.username) }}">Profile</a>
      {% endif %}
      <a href="{{ url_for('news') }}">Home</a>
      <a href="{{ url_for('about') }}">About</a>
      <a href="{{ url_for('explore') }}">Explore</a>
      <a href="{{ url_for('videos') }}">Videos</a>
      <a href="{{ url_for('music') }}">Music</a>
    </div>

    {% block content %}
          <h1>Hi, {{ current_user.username }}!</h1>
    {% endblock %}

    {% block app_content %}{% endblock %}

    {% block scripts %}
        {{ super() }}
        {{ moment.include_moment() }}
    {% endblock %}
  </body>
</html>

init.py

import logging
from logging.handlers import SMTPHandler, RotatingFileHandler
import os
from flask import Flask
from flask_sqlalchemy import SQLAlchemy
from flask_migrate import Migrate
from flask_login import LoginManager
from config import Config
from flask_mail import Mail
from flask_bootstrap import Bootstrap
from flask_moment import Moment

app = Flask(__name__)
Bootstrap(app)
app.config.from_object(Config)
db = SQLAlchemy(app)
migrate = Migrate(app, db)
login = LoginManager(app)
login.login_view = 'login'
mail = Mail(app)
moment = Moment(app)

from app import models, errors

所以现在我已经记下了，我的错误（在我将索引更改为 index.html 中的基数之后）：

       -> no match

还有我改之前的错误：

jinja2.exceptions.TemplateNotFound: bootstrap/index.html

现在这一次我的问题没有被任何一般性答案关闭（我可能会注意到这与本网站的目的相反）这里有什么问题吗？我初始化 flask-bootstrap 的方式有问题吗？还是我需要在终端中输入一些命令？随时提问，如果这是我遗漏的简单问题，非常感谢。我为任何不必要的态度道歉，我只是对那个以“信息不足”为由锁定我最后一个问题的人感到失望。

Answer 1

您的初始化方式存在问题 flask-bootstrap。你应该如何去做：

# Your previous imports
from flask_bootstrap import Bootstrap

app = Flask(__name__)

bootstrap = Bootstrap(app)

# ...

基本上，更新行：

Bootstrap(app)

至：

bootstrap = Bootstrap(app)

这也正是您对其他安装包所做的。

在您的基本模板（即父模板）中维护行 {% extends 'bootstrap/base.html' %}。不要将其更改为 {% extends 'bootstrap/index.html' %} 此文件继承了 bootstrap 的基本模板的样式、布局、功能等。

<!-- base.html -->




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

{% block head %}
    <!-- Head information goes here -->
{% endblock %}

{% block navbar %}
    <!-- Your navbar goes here -->
{% endblock %}

{% block content %}
<!-- flash message goes here -->

    {% block app_content %}
        <!-- Content from your custom HTML templates will go here -->
    {% endblock %}

{% endblock %}

{% block scripts %}
    <!-- Your scripts go here -->
{% endblock %}

在继承您的 base,html 的 index.html 文件中，您将执行：

<!-- index.html -->


{% extends 'base.html' %}

{% block app_content %}
    <!-- Content goes here -->
{% endblock %}

再问：Flask-Bootstrap怎么了？
