Django顯示來自模型的視頻

我有一個模型，其中包含上傳到我的 media/videos 檔案夾的視頻檔案。當我在管理頁面上時，我可以看到視頻并播放它。我現在試圖在模板上呈現它，但它不允許我。

這是我的模型：

class CheckList(models.Model):

choices = (('', 'Select'), ('Good', 'Good'), ('Not Good', 'Not Good'))
fuel_choices = (('', 'Select'), ('Full', 'Full'), ('3 Quarters', '3 Quarters'), ('Half Tank', 'Half Tank'), ('Almost Empty', 'Almost Empty'))
cargo_choices = (('', 'Select'), ('Cargo Secured', 'Cargo Secured'), ('Cargo Not Secured', 'Cargo Not Secured'), ('No Cargo', 'No Cargo'))

vehicle = models.ForeignKey(Trucks, on_delete=models.CASCADE, blank=True, null=True)
driver = models.ForeignKey(User, on_delete=models.CASCADE)
breaks = models.CharField(null=False, choices=choices, max_length=50, default='Select')
wipers = models.CharField(null=False, choices=choices, max_length=50, default='Select')
wiper_fluid = models.CharField(null=False, choices=choices, max_length=50, default='Select')
cargo = models.CharField(null=False, choices=cargo_choices, max_length=50, default='Select')
cargo_straps = models.CharField(null=False, choices=choices, max_length=50, default='Select')
tires = models.CharField(null=False, choices=choices, max_length=50, default='Select')
oil = models.CharField(null=False, choices=choices, max_length=50, default='Select')
miles = models.IntegerField(null=False, default='0')
gas = models.CharField(null=False, choices=fuel_choices, max_length=100, default='Select')
seatbelt = models.CharField(null=False, choices=choices, max_length=100, default='Good')
date_created = models.DateTimeField(auto_created=True)

# Need video of vehicle
video = models.FileField(upload_to='videos/')

def __str__(self):
    return self.vehicle.nickname

我處理頁面渲染的視圖：

@login_required()
def report_detail(request, pk):
    checklist = CheckList.objects.get(pk=pk)
    context = {'checklist': checklist}
    return render(request, 'driver/report_detail.html', context)

以及我嘗試加載視頻的模板：

{% extends 'user_area/base.html' %}
{% block title %}
Fleet Manager
{% endblock title %}

{% block content %}

{% include 'user_area/components/weather.html' %}

{% if user.is_authenticated %}

<div style="margin-top: 30px; margin-left: 50px">
    <h4>Vehicle: {{ checklist.vehicle}}</h4>
    Driver: {{checklist.driver}} <br>
    Breaks Status: {{checklist.breaks}} <br>
    Wipers Status: {{checklist.wipers}} <br>
    Wiper Fluid: {{checklist.wiper_fluid}} <br>
    Cargo Status: {{checklist.cargo}} <br>
    Cargo Straps Status: {{checklist.cargo_straps}} <br>
    Tires Status: {{checklist.tires}} <br>
    Oil Status: {{checklist.oil}} <br>
    Miles Out: {{checklist.miles}} <br>
    Gas: {{checklist.gas}} <br>
    Seatbelt Status: {{checklist.seatbelt}} <br>
    Vehicle Taken out on: {{checklist.date_created}} <br>
    <video width="320" height="240" controls>
<source src="{{checklist.video}}" type="video/mp4">
Your browser does not support the video tag.
</video>
    Your browser does not support the video tag.
</video>

</div>



{% else %}
<a href="{% url 'user_area:home' %}">Please login</a>

{% endif %}
{% endblock %}

現在我的問題是，如果視頻是在 checklist.video 下“保存”的，并且它在我的媒體檔案夾中，我如何將模板指向它以便呈現它？

編輯** 我在 HTML 中更改了一些內容，它顯示了視頻的路徑，但不播放。

uj5u.com熱心網友回復：

您必須使用以下模板中的視頻網址checklist.video.url：

<source src="{{ checklist.video.url }}" type="video/mp4">
