I tried every solution with no hope.

CodePudding user response：

It seems like it's just car 4 that has no image associated with it. Look at the admin. Car 4 exists, but it has no image associated with it, and your template is not checking for that.

{% if car.car_photo_4 %}   <!-- just checks if car_photo_4 exists, which it does -->

So try changing it to:

{% if car.car_photo_4.url %}

Note that this is probably also not correct, but I'd need to see your Car model to make it better.

CodePudding user response：

Your issue here is that by checking for {% if car.car_photo_4 %}, you're effectively checking if the attribute exists for this model (which it does, it's just empty). Since we know that car_photo_4 is always defined for the Car model, you should be checking that the url attribute is not empty or null.

You can do this by:

{% if car.car_photo_4.url %}

As a side note, you should use a ManyToManyField instead of statically defining the images as attributes to the Car model as it makes it simply to add more images for the Car model.
