how i should add images from DB to the recycleview ???
Elliot Garbus
Here is at least one issue:
data: [{'source': root.images, 'title': get_display(arabic_reshaper.reshape(n))} for n in root.data_items]
You are setting source to the entire list root.images. I assume the images list is a list of filenames.
If so you want something like:
data: [{'source': root.images[i], 'title': get_display(arabic_reshaper.reshape(n))} for i, n in enumerate(root.data_items)]

[{'source': [i], 'title': get_display(arabic_reshaper.reshape(n))} for i,n in enumerate(root.images,root.data_items)]
The line above a valid Python statement. Example:
>>> a
['A0', 'A1', 'A2', 'A3', 'A4', 'A5', 'A6', 'A7', 'A8', 'A9']
>>> b
['B0', 'B1', 'B2', 'B3', 'B4', 'B5', 'B6', 'B7', 'B8', 'B9']
>>> for i, d in enumerate(b):
print(f'i: {i}, a[i]: {a[i]}, d: {d}')
i: 0, a[i]: A0, d: B0
i: 1, a[i]: A1, d: B1
i: 2, a[i]: A2, d: B2
i: 3, a[i]: A3, d: B3
i: 4, a[i]: A4, d: B4
i: 5, a[i]: A5, d: B5
i: 6, a[i]: A6, d: B6
i: 7, a[i]: A7, d: B7
i: 8, a[i]: A8, d: B8
i: 9, a[i]: A9, d: B9
>>>
You could say:
[{'source': root.images[i], 'title': get_display(arabic_reshaper.reshape(data_item))} for i, data_item in enumerate(root.data_items)]

I see 2 errors below:
IndexError: list index out of range
It appears there are not the same number of items in root.data_items and root.images. Is this correct?
ValueError: ImageAndTitle.source accept only str
What is the content of root.images[i] ?
If you print(type(root.images[0]) what is printed?

if i print root.images in kv file will give me again the : IndexError: list index out of range

Please attach a more complete section of code.
As I understand it. You are pulling images from the database, and writing them to files. The filenames are being stored in a list, images.
Print the len(root.images) and print(len(root.data_items)) are they the same?
Print root.images is it the expected list of filenames?
