    <p>I'm a web dev. noobie and I'm putting together a simple signup page as practice using Python on GoogleApp Engine. </p> <p>When the signup form is filled out incorrectly, the program works fine. When it's filled out correctly, it's supposed to redirect to a thank you page but instead I get a server error:</p> <pre><code>Internal Server Error The server has either erred or is incapable of performing the requested operation.

    1. COI suspect somewhere you've accidentally overwritten self.response with a unicode object. When it tries to call it later, it tries to call your string.

    2. COYour, indentation seems fairly broken by the way, and this being Python it's hard for anyone else to tell what your intent was.

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.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
