FileField Size and Name in Template

django, django-file-upload, django-templates

Solution

Once you've got access to the value of a `FileField`, you've got a value of type `File`, which has the following methods:

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

`File.size` The size of the file in bytes.

So you can do this in your template:

{% for download in downloads %}
    <div class="download">
        <div class="title">{{download.file.name}}</div>
        <div class="size">{{download.file.size}} bytes</div>
        <div class="desc">{{download.desc}}</div>
    </div>
{% endfor %}

To get a more human-readable filesize (for those of your users who would be confused by seeing 64.5 MB as 67633152 bytes - I call them wusses), then you might be interested in the `filesizeformat` filter, for turning sizes in bytes into things like `13 KB`, `4.1 MB`, `102 bytes`, etc, which you use in your template like this:

<div class="size">{{download.file.size|filesizeformat}}</div>

Problem

How do I get the size and name of a FileField in a template? My model is setup like this: ``` class PDFUpload(models.Model): user = models.ForeignKey(User, editable=False) desc = models.CharField(max_length=255) file = models.FileField(upload_to=upload_pdf) ``` My template is setup like this: ``` {% for download in downloads %} <div class="download"> <div class="title"> Name</div> <div class="size">64.5 MB</div> <div class="desc">{{download.desc}}</div> </div> {% endfor %} ``` How can I display the file name and size?
