Module development and code questions

Hi, 

I would like to add an image field which will be url to the image in my rss views however I only get these options when clicked on fields | settings:

Title field, link field, description field, creator field, publication date field. 

I also tried using this patch - https://www.drupal.org/project/drupal/issues/2511878 but no luck. 

and tried to create a field in RSSFields.php but again no luck. 

Does anyone have any other better way?

Hello,

In my site, I let my Users to redeem coupons from a list of available coupons stored in a database table.

I would like to know what is a good way to implement this.

In a DB usually you will have a table like user_redemption to store the user_id and coupon_id as a composite key.

How would you do that in Drupal 8?

Should I create two custom Entities: Redemption, Coupon? And then use Field Definition of 'entity_reference' to link them?

Also I will have a large amount of coupons, what is a good way to insert them to my entity tables?
