Hello, I’m developing an app where a user can post an image and another user can like it. I have collections of users, posts, and likes. For each post that a user is viewing, the user can like it, which creates a new record in the Like collection. A user should also be able to unlike it, which is supposed to delete the like it previously created in the Like collection. However, the Like collection does not appear in a button’s delete action list. Like and Post is linked in a one-to-many relationship: one post can have multiple likes from different users. How can I be able to delete the link a user created? ---

Hi @bwuzhang , If you create many-to-many relationship between posts and likes, there should be an update action with remove like available. ---

Hi @Yongki , creating likes with many-to-many relationship does not work for me. In this case, when creating a new like, the post field does not even exist, resulting in empty fields in the Collection. The delete option is not available either. ![image](https://us1.discourse-cdn.com/flex020/uploads/adalo/original/3X/0/b/0b723dfc2cbf4d06340c0990f79b0b202b77e0b8.jpeg) ---

Try update action with add to. ---

@Yongki Can you elaborate on how to update action with add to? Didn’t have luck poking around. ---

Hi @bwuzhang, There are 2 possible approaches to creating “Likes”. The first one is having many-to-many relationships between Images and Users, so that one Image can be liked by many Users and a User can like many Images. This is explained here: [How to create a "Favorite" button - Adalo Resources](https://help.adalo.com/how-to/how-to-create-a-favorite-button) Another approach is having a separate collection to store “Likes” (you can include other data there as well). I’ve made quite a few videos about this in the past - not directly related to your exact case, but approach will be similar: - [Adalo Mini-app series: Followers, Influencers and follow requests - using separate collection - YouTube](https://youtu.be/_HS9WkDJbRk) - [Adalo Help: Upvotes and Downvotes - YouTube](https://youtu.be/_jPUMDLVwoA) - [Adalo Help: Upvotes & Downvotes for Posts, pt1 - application preparation, adding Posts functionality - YouTube](https://youtu.be/b0Lw8jgLaLk) - [Adalo Help: Upvotes & Downvotes for Posts - continued! Part 2: main functionality - YouTube](https://youtu.be/wXWgBV78yUQ) Hope this helps. Best, Victor. ---
