    <p>I have this dictionary in my apps model file:</p> <pre><code>TYPE_DICT = ( ("1", "Shopping list"), ("2", "Gift Wishlist"), ("3", "test list type"), ) </code></pre> <p>model, which uses this dict is this:</p> <pre><code>class List(models.Model): user = models.ForeignKey(User) name = models.CharField(max_length=200) type = models.PositiveIntegerField(choices=TYPE_DICT) </code></pre> <p>I want to re-use it in my views and imported it from apps.models. I am creating a list of dictioneries to use in my view like this:</p> <pre><code>bunchofdicts = List.objects.filter(user=request.user) array = [] for dict in bunchofdicts: ListDict = {'Name':dict.name, 'type':TYPE_DICT[dict.type], 'edit':'placeholder' } array.append(ListDict) </code></pre> <p>When i use this list in my template then it gives me very strange results. Instead of returning me the type of the list (shopping list) it returns me ('2', 'Gift Wishlist').</p> <p>So i can understand what it is doing (in ths case, the dict.type equals 1, and it should return me "shopping list" , but it returns me [1] - second, element in list). What i do not understand, why doing exactly the same thing in python shell gives different results.</p> <p>doing it the way i do in django ( TYPE_DICT[dict.type] ), works as described above and creates error in python shell. using TYPE_DICT[str(dict.type)] in python shell works just fine, but creates this error in django:</p> <pre><code>TypeError at /list/ tuple indices must be integers, not str Request Method: GET Request URL: http://127.0.0.1/list/ Exception Type: TypeError Exception Value: tuple indices must be integers, not str Exception Location: /home/projects/tst/list/views.py in list, line 22 Python Executable: /usr/bin/python Python Version: 2.6.2 </code></pre> <p>Perhaps i did something wrong or different in python shell. What i did was:</p> <pre><code>python Python 2.6.2 (release26-maint, Apr 19 2009, 01:56:41) [GCC 4.3.3] on linux2 Type "help", "copyright", "credits" or "license" for more information. &gt;&gt;&gt; dict = {'1':'shoppinglist', '2':'giftlist','3':'testlist'} &gt;&gt;&gt; print dict[1] Traceback (most recent call last): File "&lt;stdin&gt;", line 1, in &lt;module&gt; KeyError: 1 &gt;&gt;&gt; print dict[str(1)] shoppinglist &gt;&gt;&gt; x = 1 &gt;&gt;&gt; print dict[x] Traceback (most recent call last): File "&lt;stdin&gt;", line 1, in &lt;module&gt; KeyError: 1 &gt;&gt;&gt; print dict[str(x)] shoppinglist &gt;&gt;&gt; </code></pre> <p>so what is wrong here?</p> <p>Alan</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.
