Django FileField: How to return filename only (in template)

问题

I've got a field in my model of type FileField. This gives me an object of type File, which has the following method:

File.name: The name of the file including the relative path from MEDIA_ROOT.

What I want is something like ".filename" that will only give me the filename and not the path as well, something like:

{% for download in downloads %}
  <div class="download">
    <div class="title">{{download.file.filename}}</div>
  </div>
{% endfor %}

Which would give something like myfile.jpg

In your model definition:

import os

class File(models.Model):
    file = models.FileField()
    ...

    def filename(self):
        return os.path.basename(self.file.name)

You can do this by creating a template filter:

In myapp/templatetags/filename.py:

import os

from django import template


register = template.Library()

@register.filter
def filename(value):
    return os.path.basename(value.file.name)

And then in your template:

{% load filename %}

{# ... #}

{% for download in downloads %}
  <div class="download">
      <div class="title">{{download.file|filename}}</div>
  </div>
{% endfor %}

You can access the filename from the file field object with the name property.

class CsvJob(Models.model):

    file = models.FileField()

then you can get the particular objects filename using.

obj = CsvJob.objects.get()
obj.file.name property
