Question

我正在使用django-easy-pdf，我有以下观点：

class PrescriptionView(PDFTemplateView):
    template_name = 'meds/prescription.html'
    context_object_name = 'meds'
    model = Medicament

    def get_queryset(self):
        ids = map(int, self.kwargs['selected'].split(","))
        return Medicament.objects.filter(id__in=ids)

    def get_context_data(self, **kwargs):
        context = super(PrescriptionView, self).get_context_data(pagesize="A5", title="Ordonnance", **kwargs)
        return context

我有以下html页面：

{% load staticfiles %}
<html>
    <head>
        <meta charset="UTF-8">
        <style>
            @page { size: A5;
                @frame headerLogo {
                    top: 23mm;
                    left: 20mm;
                    width: 50mm;
                    height: 24mm;
                    -pdf-frame-content: headerLogo;
                }
            }
        </style>
    </head>
    <body>
    <div id="headerLogo">
        <img src="{% static 'img/banner.png' %}">
    </div>
</body>

但是banner.png图片没有加载，我不断收到以下错误：

missing explicit frame definition for content or just static frames

getFile '/static/img/banner.png' None '/home/nids/cabin'
'<div id="headerLogo"> <img src="/static/img/banner.png"/> </div>'

Need a valid file name!

我的静态文件在其他视图中没有问题，除了这个pdf one！

差不多10个小时试图解决这个问题，并且OH MA GOD，它已经解决了。问题非常简单 - 重新安装此软件包

1.pip install --pre xhtml2pdf。

2.pip install --pre reportlab。

3.pip install django-easy-pdf。

请记住在之前卸载此命令。还有一件事，尝试在纯HTML上设置高度和宽度为img标签。

Django - 使用pdf视图时不加载图像
