Question

我正在编写一个从数据库中获取文件名并输出相关图像的应用程序。但是，django模板似乎无法解析我的请求

这是django视图：

def nii2(request):
    conn_str_file = os.path.join(os.path.dirname(os.path.abspath(__file__)),
                                 'connection_string.txt')
    connection_string = open(conn_str_file).read()
    cursor = db.connect(connection_string).cursor()
    sql = '''
    SELECT img.[djangoFileLoc]
    FROM [image_locations$] img,
    [Metadata$] meta
    WHERE img.[originalFileName] = meta.[originalFileName]
    '''
    if 'Machine' in request.GET:
        sql += 'AND Machine = %r' % request.GET['Machine']
    if 'Dir' in request.GET:
        if request.GET['Dir'] != 'Both':
            sql += ' AND Dir = %r' % request.GET['Dir']
    sql += ' ORDER BY img.[originalFileName]'
    djangoImages = []
    sql += ';'
    data = cursor.execute(sql)
    for row in data:
        djangoImages.append(row[0])
    context = {"imageLoc": djangoImages[0:21]}
    return render(request, 'template.html', context)

这是template.html：

{% extends "images.html" %}
{% load staticfiles %}
{% block images %}
{% for img in imageLoc %}
<a><img onmouseover="previewFunction('{% static '{{img}}' %}', 'Image One', 'Detailed info on Image one')"
                src='{% static '{{img}}' %}' title ="Image 1"/></a> 

{% endfor %}
{% endblock %}

这就是输出源的结果：

<a><img onmouseover="previewFunction('/static/%7B%7Bimg%7D%7D', 'Image One', 'Detailed info on Image one')"
                src='/static/%7B%7Bimg%7D%7D' title ="Image 1"/></a> 


<a><img onmouseover="previewFunction('/static/%7B%7Bimg%7D%7D', 'Image One', 'Detailed info on Image one')"
                src='/static/%7B%7Bimg%7D%7D' title ="Image 1"/></a> 


<a><img onmouseover="previewFunction('/static/%7B%7Bimg%7D%7D', 'Image One', 'Detailed info on Image one')"
                src='/static/%7B%7Bimg%7D%7D' title ="Image 1"/></a> 


<a><img onmouseover="previewFunction('/static/%7B%7Bimg%7D%7D', 'Image One', 'Detailed info on Image one')"
                src='/static/%7B%7Bimg%7D%7D' title ="Image 1"/></a> 


<a><img onmouseover="previewFunction('/static/%7B%7Bimg%7D%7D', 'Image One', 'Detailed info on Image one')"

因此，不是从列表中插入文件名，而是只读取变量。

有没有人对如何解决这个问题有任何想法？

经过一周的思考，制动并在这里发布问题后，我发布后终于找到了解决方案。我刚删除变量周围的括号：

＆＃13;

{% extends "images.html" %}
{% load staticfiles %}
{% block images %}
{% for img in imageLoc %}
<a><img onmouseover="previewFunction('{% static img %}', 'Image One', 'Detailed info on Image one')"
                src='{% static img %}' title ="Image 1"/></a> 

{% endfor %}
{% endblock %}

＆＃13;

从for循环中的文件名访问django中的静态文件
