I gotta do a notes app so I decided to use summernote and python flask for this.

(我得做一个笔记应用程序，所以我决定为此使用summernote和python flask 。)

I got a form where the user has to input the title and the content using a summernote textarea then the input is stored in the DB.

(我得到了一个表单，用户必须使用summernote文本区域输入标题和内容，然后将输入存储在DB中。)

The problem that I got is when I try to display the notes they come as plain text

(我遇到的问题是当我尝试将注释以纯文本形式显示时)

this is how I display them

(这就是我显示它们的方式)

            {% for foo in notes %}
                <div class="card">
                    <div class="card-header">
                        <div class="card-title">{{ foo.title }}</div>
                    </div>
                    <div class="card-body">
                        <div class="ribbon-wrapper ribbon-lg">
                        <div class="ribbon bg-primary">
                            <p>{{ foo.category_name }}</p>
                        </div>
                    </div>
                        {{ foo.content }}
                    </div>
                    <div class="card-footer">
                        <a href="#" class="btn btn-info btn-xs"><i class="fas fa-eye"></i></a>
                        <a href="#" class="btn btn-danger btn-xs"><i class="fas fa-trash"></i></a>
                    </div>
                </div>
            {% endfor %}

Is there any way that I could actually render the HTML content instead of displaying it as plain text?

(有什么方法可以实际呈现HTML内容，而不是将其显示为纯文本？)
