使用嵌入标签从文件 DJANGO 加载 PDF 失败

Question

>我试图加载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 它是保存文档的 URL(在我的例子中是"课程/CV_2017.pdf"(

它抛出我 无法加载资源：404 未找到 http://127.0.0.1:8000/INTRANET/uploads/curriculums/CV_2017.pdf

但是有保存PDF的地方

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)

Answer 1

如果您的根urls.py中没有此行，请添加它

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

注意：这仅适用于开发中

您的MEDIA_URL应以/开头。
所以代替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： 代替../uploads/{{ documento.adjunto }}，添加{{ documento.adjunto.url }}

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

Answer 2

你也可以使用

doc = doc_models.objects.all()
<a href="{{doc.url}}">Pdf</a>
