    <p>Thank you for your code, I've just tested it. But it's not exactly what I'm looking for, I will explain what I want to do. </p> <p>Let's say that we have Category and Article classes in our model, each one has a title. To make this title reusable, I created another application that will manage fields, I created the class Title and I added it as foreignkey to Category and Article forms.</p> <p>I switched the select box to an input field using raw_id_fields.</p> <p>Now, when I create a category or an article, I have to select or write a title, when this title exists, it works perfectly but when it doesn't exist I want to create it before creating the category so it can use it.</p> <p>I tried to do that in the save method, in the pre_save signal and in the clean method but I always get the error "Select a valid choice. That choice is not one of the available choices."</p> <p>I'm using a hard coded solution to create the title now, I want just to see if it will work, these are the lines that I inserted in the different methods to create the title before creating the category :</p> <pre><code>t = Title(title = "MyTitle") t.save()</code></pre> <p>I tried to create a Category with MyTitle as title but I get the same error, when I try to create another one using an existing title, it works and the title "MyTitle" is created. That's mean that the creation of the object happens after the form verification. What I want is just doing this before. The title object should be created before the verification.</p> <p>Thank you very much for your help</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.
