django - 使用嵌入标签从文件 DJANGO 加载 PDF 失败

Question

我正在尝试加载 PDF

我的.html

<div class="container">
    <div class="row">
        <div class="col-lg-12">
            <embed src="{{ documento.adjunto.url }}" type="application/pdf" width="100%" height="600px" />
        </div>>
    </div>
</div>

其中 documento.adjunto 是保存文档的 url（在我的例子中是“curriculums/CV_2017.pdf”）

它让我无法加载资源：找不到 404 http://127.0.0.1:8000/INTRANET/uploads/curriculums/CV_2017.pdf

但是有保存PDF的地方

模型：

UPLOAD_CVS = "curriculums/"
class Curriculum(models.Model):
    rut_candidato = models.ForeignKey(Candidato, on_delete=models.CASCADE)
    adjunto = models.FileField(upload_to=UPLOAD_CVS)
    fecha_ingreso_cv = models.DateField(_("Date"), auto_now_add=True)

    def get_ultima_actualizacion(self):
        actual = datetime.now().date()
        return int(round((actual - self.fecha_ingreso_cv).days / 365,0))

    def get_cv_name(self):
        return 
       "CV_"+self.rut_candidato.nombre+"_"+self.rut_candidato.apellido+"_"+ str(self.fecha_ingreso_cv)

设置.py：

如果您的根目录中没有此行，请urls.py添加它

urlpatterns += static(settings.MEDIA_URL,document_root=settings.MEDIA_ROOT)

注意：这仅在开发中有效

您MEDIA_URL应该以/.
所以，而不是MEDIA_URL = 'INTRANET/uploads/'，添加这个：

MEDIA_URL = '/INTRANET/uploads/' 
MEDIA_ROOT = os.path.join(BASE_DIR, 'INTRANET/uploads') # no Slash before  and after

在模板中，你甚至不需要添加路径，Django 会生成它：而不是../uploads/{{ documento.adjunto }}，添加{{ documento.adjunto.url }}

<embed src="{{ documento.adjunto.url }}"
       type="application/pdf" width="100%" height="600px" />
