    <p>I am trying to figure out how to display a form based on data from a table. I basically want to use the data from one table as a label to enter data that goes into another table.</p> <p>I have two food tables:</p> <pre><code>class FoodType(models.Model): name = models.CharField(max_length=200) class Food(models.Model): foodtype = models.ForeignKey(FoodType) tracktemp = models.BooleanField(verbose_name="Track Temperature?") </code></pre> <p>and a Temp table like this:</p> <pre><code>class Temp(models.Model): date = models.DateField('Entry Date') time = models.TimeField('Entry Time') food = models.ForeignKey(Food) temp = models.IntegerField(max_length=4, blank=True, null=True) </code></pre> <p>I have two foods in my <code>Food</code> table (Beans, Sprouts) and <code>tracktemp</code> is set to <code>True</code> for each of them.</p> <p>In the Temp table I want to be able to add multiple records, each of which has a single temp at a particular time. For example:</p> <pre><code>Beans 1st Dec 2012 6.00pm 230 Beans 1st Dec 2012 6.04pm 235 Beans 1st Dec 2012 6.10pm 240 </code></pre> <p>To do this I want to be able to render a form like this to enter the temps:</p> <pre><code>Beans [ ] Sprouts [ ] [save] </code></pre> <p>Some notes about the above form:</p> <ul> <li>The food names should be labels, not combo boxes.</li> <li>I will not show the date/time fields and just programmatically set them.</li> </ul> <p>As such I need to find all items in the Food table that have <code>tracktemp</code> set to 'True' and use that to present a form to the user so the user can add a temp for that time.</p> <p>How can I do this?</p>

    1. COWhat have you tried? This sounds like a homework question that you have done zero research on, as even rudimentary research into Django querysets would give you the answer you need.

    2. COThis isn't a homework question. It is part of a project I am working on. I first tried to run a query to get the items from Food and then iterate through and generate a form. I could not get the items to iterate. I then tried a formset, but I got a little confused about whether I run the formset on Food or Temp.

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.
