    <p>If I have a MultiValueField on one of my search indexes, and I want to display each value in the search results, how would I do that? It seems like something is not being formatted appropriately or I am somehow misunderstanding the MultiValueField?</p> <pre><code>class PageAttachmentIndex(indexes.SearchIndex): # This should reference search/indexes/pages/pageattachment_text.txt text = indexes.CharField(document=True, use_template=True) title = indexes.CharField(model_attr='name') page = indexes.IntegerField(model_attr='page_id') attrs = indexes.MultiValueField() file = indexes.CharField(model_attr='file') filesize = indexes.IntegerField(model_attr='file__size') timestamp = indexes.DateTimeField(model_attr='timestamp') url = indexes.CharField(model_attr='page') def prepare_attrs(self, obj): """ Prepare the attributes for any file attachments on the current page as specified in the M2M relationship. """ # Add in attributes (assuming there's a M2M relationship to # attachment attributes on the model.) Note that this will NOT # get picked up by the automatic schema tools provided by haystack attributes = obj.attributes.all() return attributes </code></pre> <p>In leveraging this in my template view:</p> <pre><code> {% if result.attrs|length %} &lt;div class="attributes"&gt; &lt;ul&gt; {% for a in result.attrs %} &lt;li class="{% cycle "clear" "" "" %}"&gt;&lt;span class="name"&gt;{{ a.name }}&lt;/span&gt;: &lt;span class="value"&gt;{{ a.value }}&lt;/span&gt;&lt;/li&gt; {% endfor %} &lt;/ul&gt; &lt;div class="clear"&gt;&lt;/div&gt; &lt;/div&gt; {% endif %} </code></pre> <p>This seems to return nothing for me :(</p>

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.
