Changes between Initial Version and Version 1 of Ticket #13848

-              initial
+              v1
 Below is the code to duplicate it:
+{{{
 class Foo(models.Model):
     title = models.CharField(max_length=50)
 …
 class Photo(models.Model):
     image = models.ImageField(upload_to='')
+}}}
 In a view I pass all Foos objects to the template. And attempt to retrieve just the first image to be displayed but first it is passed to a filter to create a thubmnail.
 Here is the rough template code that generates the error: Caught AttributeError while rendering: 'str' object has no attribute 'path'.
+{{{
 {% for foo in foos %}
    <img alt='image' src='{{ foo.photo_set.all.0.image|thumbnail:'200x200 }}
 {% endfor %}
+}}}
 The thumbnail filter is called twice - print typeof(file) statement in the filter outputs:
+{{{
 <class 'django.db.models.fields.files.ImageFieldFile'>
 <type 'str'>
+}}}
 A workarround is insert another loop like this:
+{{{
 {% for foo in foos %}
    {% for photo in foo.photo_set.all %}
 …
    {% endfor %}
 {% endfor %}
+}}}
 Thank you for looking into it.
