第七章

创建目录模板（templates） 下最后一个代码块中：

{% extends "shop/base.html" %}
{% load static %}

{% block title %}
    {% if category %}{{ category.title }}{% else %}Products{% endif %}
{% endblock %}

{% block content %}
    <div class="product-detail">
        ![]({% if product.image %}{{ product.image.url }}{% else %}{% static )
        <h1>{{ product.name }}</h1>
        <h2><a href="{{ product.category.get_absolute_url }}">{{ product.category }}</a></h2>
        <p class="price">${{ product.price }}</p>
            {{ product.description|linebreaks }}
    </div>
{% endblock %}

其中

![]({% if product.image %}{{ product.image.url }}{% else %}{% static )

应该是

<img src="{% if product.image %}{{ product.image.url }}{% else %}{% static "img/no_image.png" %}{% endif %}">

我正在看，顺便修订下😁

In the code from email part, there is a line
request.build_absolute_url
However,build_absolute_uri() should be the correct API, as far as I'm concerned.

Same part
return render(request, 'blog/post/share.html', {'post': post, 'form': form, 'sent': sent})
only post,form,sent is rendered to template: share.html
but in share.html, "{{ post.title }}" was successfully sent to {{ cd.to }}. also involves cd

我可以转载到自己的网站吗？
署名，会贴上原地址。
就是自己看着方便

仓库为

author = models.ForeignKey(User,
                                related_name='blog_posts')

应当补充参数
author = models.ForeignKey(User, related_name='blog_posts', on_delete=models.CASCADE)

文章五分之四处，字符翻译错误, 原句为：
”只要你喜欢你可以连接许多模板标签（tempalte filters），每一个都会应用到上个输出生成的结果上。“

更正为：
”只要你喜欢你可以连接许多模板标签（template tag），每一个都会应用到上个输出生成的结果上。“
