    <p>I am trying to load data from a database into a html page. basically when a user access their profile and clicks on "Purchase History" it should query the database and display all the products the user has purchased. </p> <p>I am trying to do this using ajax and json, but i get an error:</p> <pre><code>TypeError: &lt;gluon.dal.Field object at 0x091CCD90&gt; is not JSON serializable </code></pre> <p>Below is the code:</p> <pre><code>def prodHistoryJson(): productName = db.sale.title productCost = db.sale.price prodShipAdd = db.sale.shipping_address prodShipCity = db.sale.shipping_city prodShipState = db.sale.shipping_state prodShipZipCode = db.sale.shipping_zip_code myproducts = {'prodName':productName, 'cost':productCost, 'shipAdd':prodShipAdd, 'shipCity':prodShipCity, 'shipState':prodShipState, 'shipZipCode':prodShipZipCode} import gluon.contrib.simplejson as json returnData = json.dumps(myproducts) return returnData </code></pre> <p>below is the jquery:</p> <pre><code>$.ajax( { url:'/suzannecollins/onlineStore/prodHistoryJson', data: { message: "Your products purchase history is listed below" }, success: function(msg) { try { myproducts=JSON.parse(msg); } catch(err) { console.log(" error"); } // place returned value in the DOM $('#returnData').html(myproducts.title + myproducts.price + myproducts.shipping_address + myproduct.shipping_state + myproducts.shipping_city + myproducts.shipping_zip_code); } }); </code></pre> <p>what am i doing wrong? I can get this all to work if i just do this in a simpler way where a user hits the purchase_History button and it queries the database and displays the products purchased. How do i do the same thing with the code above?</p>

    1. COThis has nothing to do with jQuery. `gluon.dal.Field` can not be serialized to JSON.

    2. COIt seems like `db.sale.title` etc. are not strings you hope for, but rather the field descriptors. How are you getting those?

    3. COSide note: remove the `try-catch` in your AJAX code. It's better to see mistakes due to the page not loading correctly, rather than silently sweeping them to the console where you'll never see them. As it's structured right now, your code might throw an exception yet still try to modify the page, which doesn't make sense.

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).
