    <p>I need to iterate through a tuple in the template, but from the code i've built i am getting a tuple of an object (album) and a queryset (photo). The problem is how do i iterate over them now in the template?</p> <p>models:</p> <pre><code>class Album(models.Model): title = models.CharField('כותרת', max_length=100, db_index=True) created = models.DateTimeField('תאריך פרסום', auto_now_add=True) creator = models.ForeignKey(User, related_name='galleries_creator', verbose_name='נכתב ע"י') class Photo(models.Model): title = models.CharField('כותרת', max_length=100) album = models.ForeignKey(Album, verbose_name='שייך לאלבום') photo = models.ImageField('תמונה', blank=True, upload_to=get_image_path) photo_mid = models.ImageField('תמונה בינונית', blank=True, upload_to='images/galleries/mid/', editable=False) photo_thumb = models.ImageField('תמונה קטנה', blank=True, upload_to='images/galleries/thumbs/', editable=False) created = models.DateTimeField('תאריך פרסום', auto_now_add=True) is_landscape = models.NullBooleanField(blank=True, verbose_name='האם תמונת לנדסקייפ', editable=False) </code></pre> <p>View:</p> <pre><code>def index(request): albums = Album.objects.all().order_by('?')[:10] album_list = [] for album in albums: album_list.append((album, Photo.objects.filter(album=album).order_by('?')[:1])) return render_to_response('galleries/index.html',{'albums':album_list}, context_instance=RequestContext(request)) </code></pre> <p>template:</p> <pre><code>{% for album, photo in albums %} &lt;div class="polaroid" id="picture_{{ forloop.counter }}"&gt; &lt;img src="{{ MEDIA_URL }}{{ photo.photo }}" alt="Picture #{{ forloop.counter }}" /&gt; &lt;p class="caption"&gt;&lt;p class="title"&gt;אלבום {{ forloop.counter }}&lt;/p&gt;&lt;p&gt;{{ album.creator.first_name }} {{ album.creator.last_name }}&lt;/p&gt; &lt;/div&gt; {% endfor %} </code></pre> <p>As i see it, i can't do photo.photo because photo is a list, not an object and i really don't want to do a for loop for every photo in the tuple (there is only one photo, so this is just a waste).</p> <p>assert False album_list returns:</p> <pre><code>[(&lt;Album: אלבום שני - ממשק מנהל&gt;, [&lt;Photo: אלבום 2 תמונה 2&gt;]), (&lt;Album: אלבום ראשון - ממשק מנהל&gt;, [&lt;Photo: אלבום 1 תמונה 7&gt;]), (&lt;Album: אלבום נתן&gt;, [&lt;Photo: נסיון 4&gt;])] </code></pre> <p>What can i do in my view or template to solve this?</p>

    1. COWhy don't you just do a nested for-loop? Or am I missing something?

    2. CO!0x, the thing is that i am trying to avoid the second loop. Loops are time and processor consumers and i already have what i need, the thing is, that i am probably doing something wrong over here, or in the view (need to return an object of Photo and not a set) or in the template, i don't think that the right way is to do a for loop for the Photo list when i only have one object over there... But maybe i am wrong...

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
