How break cycle for with if else statement in django template
I read if else statement in Django docs
but i don't understand my case.
I have photos list, i want render image if is COVER else i want render static image.
This my code
{% for x in listing.photos.all %}
{% if x.photo_tipo == 'COVER' %}
<img src="{{ x.get_thumb }}" alt="">
{% else %}
<img src="{% static 'images/about/1.jpg' %}" alt="">
{% endif %}
{% endfor %}
Result is: an image if x.photo == 'COVER' and a static image for every other photo in the list.
I would like to get only one result if the declaration is true or only one static image if it is false

Don't do this in the template. Add some logic somewhere that gives you the photo with that type directly if it exists. A good way would be with a method on the Listing model:
class Listing(models.Model):
...
def cover_photo(self):
return self.photos.filter(photo_tipo='COVER').first()
Now your template could be:
{% with photo as listing.cover_photo %}
{% if photo %}
<img src="{{ photo.get_thumb }}" alt="">
{% else %}
<img src="{% static 'images/about/1.jpg' %}" alt="">
{% endif %}
{% endwith %}

No that goes in the model of whateverlistingis, ie the thing that has the relationship to Photo.
