To provide the feature of attaching images to posts with the ability to add a text caption for each image, as is the case when publishing a post on Facebook, I can build this functionality in two ways:
1- add a data type for posts and another data type for attachments (attachment contain a field for image and another field for the text caption of the image) then link those tow data types to each other, so the posts can be displayed by a RG that search for posts and inside it another RG that search for attachments related to cell’s post.
2- add just one data type for posts contains tow list fields, one list field for images and another list field for the text captions of the images, so the posts can be displayed by a RG that search for posts and inside it another RG that display the post’s list of images (by making
current cell's post's images is the data source) and also display the text caption in each cell (by using some plugins inside the second RG to retrieve the right text caption).
Which of the two ways is better?
