    1. COYou need to fix your hashes: it's '=>', not ':' and 'nil' instead of 'null', i.e. it should look like this: `"lat" => nil`. Also you have one too many levels of arrays in the example. Unless you're actually use array of arrays of hashes.

    2. CO@TsukinoMai I think the OP actually posted JSON, and not Ruby. Otherwise yes, you'd be correct in how the hash should use `=>` instead of `:`.

    3. CO@MrDanA Well, he'll need to make it into a ruby hash if he wants to use ruby methods to grab info. In current state your solution (or any other for that matter) will just shower him with errors.

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.
