Body
i am using django 1.2 i have two models. EDIT: i just found a better example: <pre><code>class Parent(models.Model): name = models.CharField(max_length=255) favorite_child = models.ForeignKey(Child) class Child(models.Model): name = models.CharField(max_length=255) myparent = models.ForeignKey(Parent) </code></pre> in this example i would like to be able to choose a favorite child but the problem is that the admin will give me all the children to choose from and not just the ones who are the children of the parent i am currently editing. ORIGINAL EXAMPLE: <pre><code>class Version(models.Model): name = models.CharField(max_length = 255) platform = models.ForeignKey("Platform",related_name='version_platform') class Platform(models.Model): name = models.CharField(max_length = 255) default_version = models.ForeignKey(Version,related_name='platform_default_version') </code></pre> i want the django admin to limit the drop down when i choose default_version so that i will only be able to choose those versions that have the current platform. for example if i have version named '1.1' that has platform joomla and version '1.2' that has wordpress as platform. so when i will choose default_version dropdown in the admin for wordpress i want it to only show me version '1.2' in the drop down. now it shows me all of the versions. i am trying to limit limit_choices_to as shown <a href="https://code.djangoproject.com/ticket/3096" rel="nofollow">here</a> so i try this: <pre><code>class Platform(models.Model): name = models.CharField(max_length = 255) default_version = models.ForeignKey(Version,limit_choices_to={'platform':XXXXX},related_name='platform_default_version') </code></pre> but i am lost as to what to put insted of the XXXX i try putting self but it did not work. i have also tried <pre><code>limit_choices_to={'platform.name':name} </code></pre> i did not work either. in this example i would like to be able to choose a favorite child but the problem is that the admin will give me all the children to choose from and not just the ones who are the children of the parent i am currently editing.

Guidance

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.
