Dear appery staff I have a question here and hope someone can help me out.
I have N images with descriptions stored in the database. I created some pages with image component in each page. I want to make the page A randomly show one image from the database and next page, page B, randomly show one image from the N-1 images, page C, N-2 images. and so on.
Is there any tutorial I can use for my case ?
Thanks,
it seems like the old post about using the math.random() is not suitable for this case. I cant put all pictures to the app since I want to add more pictures later so I think using backend database is better than local phone storage, Please help/!
(update) currently, I use a stupid way...... I put a col in my database named "index" and place numbers there. In the page, I use math.random() to generate a random number and store it to a local variable. I tried to use a query service but it didnt work, I used the code return '{"username":"'+value+'"}'; in my query request mapping.
Please help!
sorry it is return '{"index":"'+value+'"}';
Hello,
1) Get all files and save this array into storage variable: https://devcenter.appery.io/documenta...
2) get random file using math.random() by array's index
Hi Sergiy, I am not sure I know how to get all images to a array and store them into a local storage by reading the link you sent. Can you give me some more deep tips?
Hello,
You can define your model data structure as an array, and link storage to this model, this is shown in our docs here -- https://devcenter.appery.io/documenta...
