javascript - Can't retrieve all records from Cloudkit Cloud (JS) -


i have html table want populate values stored in cloudkit dashboard.

i have retrieved records , populated tables them, , problem noticing if give time , try reload table again records not retrieved. haven't changed of code in time between, i'm puzzled how/why happening. below example of code, , error log:

public-query.js : 

records.foreach(function(record) {   var fields = record.fields;   var tableactual = "<tr><td>" + record['created'].timestamp + "</td><td>" + fields['placename'].value + </td></tr>                       document.write(tableactual)

error log:

uncaught (in promise) typeerror: cannot read property 'timestamp' of  undefined @ public-query.js:49:73 @ array.foreach (native) @ public-query.js:47:29

if remove example <td>" + record['created'].timestamp + "</td> error log next <td> undefined.

to clear, there record being retrieved timestamp correctly, , there other records being retrieved , aren't, no change in code.

i've received error @ different times in different parts of line 3 (in actual code there 16 fields/<td>) though know fields populated in record, , have retrieved records fields unpopulated.

any idea what's going on here? bug cloudkit or doing wrong?

if take @ discussion section @ bottom of cloudkit web services query reference, you'll see:

indexes updated asynchronously not guaranteed current.

it's possible records returned in query marked deleted , won't include fields, need check before assuming fields exist , access them. here example response might see:

{     "records": [{         "recordname": "195055b3-1db7-4d75-86f0-d9aef8d8381b",         "deleted": true     }, {         "recordname": "712525a8-eccf-4da7-b2d9-981f120bcc82",         "deleted": true     }],     "total": 2 }

if check deleted attribute on these objects can ignore them when processing or rendering data.

What Are The Best Universities In The World?

Harvard and Yale are often referred to as “the best of the best”. But when it comes to the highest ranked universities, these and other Ivy League schools don't even make it into the top five. So what are the world's best universities? Well, according to an index by the Times Higher Education, Stanford ranks 3rd in the world. Most people associate Stanford with tech-capital Silicon Valley, which is where the school is located. And in fact, it's largely because of Stanford that the region is now the global capital of entrepreneurship and technology. In the 1940's and 50's the university heavily encouraged students and faculty to start their own companies, eventually leading to companies like Google and Snapchat. And still today, the school is known to produce some of the most successful entrepreneurs. A Stanford degree is in extremely high demand, and the school maintains the lowest acceptance rate in the country, admitting less than 5 percent of applicants. Much ...

Hard vs. Soft Water: What's The Difference?

Hard or Soft? HOW AM I SUPPOSED TO KNOW? THEY BOTH LOOK EXACTLY THE SAME! Hey there, Sapna here for Dnews. From the outside, all water is seemingly the same: clear, mostly flavorless, two hydrogens, one oxygen. But once you get past the basics, water is actually pretty versatile. It can be distilled, filtered, tap, bottled, and if you're real fancy, there's water marketed as kosher, organic or kabbalah. But did you know water can also be hard or soft? No, this isn't to describe how the water actually feels. It actually has to do with its mineral content. Water becomes ‘hard' when it has a higher than normal concentration of minerals, primarily calcium and magnesium. Water picks up these minerals from rocks and soil as it flows through rivers, wells or other waterways. Soft water, on the other hand, has a low mineral content, either because it has not yet flowed through rocks or wells - like rain water - or because the rocks it has come in contact with have little to no...
