Hello, I am really enjoying building apps for the past year using anvil. I am currently trying to build a shopping web app and I am stuck trying to figure out the best way to create a add to cart feature. I have done it using data tables and linking it to user profile, but now i would like to use it without using data tabels.
I am trying to use the concept of populating a repeating panel from a list or a dict on the client side. But I fail at accomplishing it. I am having trouble appending one textbox value after a button click. Can someone create a simple app demonstrating this? Would be very helpful! Hopefully my request makes sense.
I really love this forum and all the support from its members.
hi @magdiel_adames, and welcome to the forum
could you share a clone link that demonstrates the behaviour you’re trying to achieve with the code you’ve tried?
someone on here will then be able to jump in and give you some suggestions.
I took this from another example that was posted in this forum. I am still new at python so I am having trouble with this. Here is a simple app that just has a textbox, button and repeating panel. I just want to understand how to enter one value and display it on the repeating panel. Then when i enter another item how to append it to the repeating panel.

so you need to adjust the itemTemplate for the repeating panel.
add a label into itemTemplate
add a databinding
and boom…
I also changed a bit of code so that the new item was
{'foo':self.text_box_1.text}

Excellent, thank you so much!
Hey thanks for the solution, I added it to my Shopping App. I am trying to add items of a repeating panel to a “Cart” which is another repeating panel but it only displays the individual dictionaries of the Products select. How can I add all the products and display it to the repeating panel on the right?
Here is my app.

each item template is its own form.
notice how in the init method you are setting self.data = []
this is true for each item template of which you have 3
So you need to keep track of the data in the cart a different way.
each item template appends the item to its own self.data attribute (so when you click a new item template you are appending it to a different list…
Here’s one way you could do it.
