Coding errors - Getdata count and Setfilter

Ask the community
, ,
1

Full disclosure - this is the first time I have attempted code like this and I am VERY much learning as I go. I have followed a Corvid tutorial (for the past 8 hours!) and now have reduced errors to two, which I cannot work out. Any help would be greatly appreciated - would be fab to have achieved something in lockdown :joy:

I am trying to add a product review function and have followed this to a T (or so I thought): https://support.wix.com/en/article/corvid-tutorial-adding-ratings-and-reviews-to-a-wix-stores-site

I have two errors attached and am out of my depthā€¦

Thanks in advance :woman_facepalming::blush:

Hello Joanna,

if you would use the CODE-TAGs to insert the code as TEXT and not as IMAGE, i could perhaps take a look at this issue. I do not want to type/write all this code by my own to reconstruct your situation :grin: I am a lazy man.

But i can already recognize some errors in your code.

if ('#review').getTotalCount() > 0) {   <<<<---- WRONG

Look at thisā€¦ (you have forget ā€”> $w(ā€¦

export function showReviews() {
 if ($w('#review').getTotalCount() > 0) {
  $w('#reviewsStrip').expand();
 } else {
  $w('#reviewsStrip').collapse();
 }
}

Second oneā€¦ (do not recognize the error but try this one)

async function initReviews() {
 await $w('#productPage1').setFilter(wixData.filter().eq('productId', product._id));
 showReviews();
 loadStatistics();
}

Thank you for such a great reply! Code is not flagging any errors now - hooray! Final issue is that the code isnā€™t loading reviews on product pages. Can you spot any similar errors in the code here? Iā€™m not sure how the code understands if there is more than one review (for the get total count), I have included a screen-grab of the database too. Thanks again!!

@joannamcgowanmusic

do you have implement the ā€œloading-partā€ to your code?

loadStatistics() //<--- this wants to start the loading process

Where is your loading part?
Do you have this part in your CODE ?

async function loadStatistics() {
 const stats = await wixData.get('review-stats', product._id); 
 if (stats) { 
 let avgRating = (Math.round(stats.rating * 10 / stats.count) / 10); 
 let percentRecommended = Math.round(stats.recommended / stats.count * 100); 
 let ratings = $w('#generalRatings');
  ratings.rating = avgRating;
  ratings.numRatings = stats.count;
  $w('#recoPercent').text = `${percentRecommended} % would recommend`; 
  $w('#generalRatings').show(); 
 } else {
  $w('#recoPercent').text = 'There are no reviews yet'; 
 }
 $w('#recoPercent').show(); 
}

Of course you have to optimize it and to modify for your own project.

Try do read the tutorial, one more time and to understand all the steps.
STEP by STEP!

@russian-dima Thank you for your reply - the issue for me with the tutorial, is that they have already set up databases/site content prior to the instructions. I went on the example site (on wix editor) and copied content so all tags are the same, but I wouldnā€™t know if I have made an error on that side of things.
