Full-Stack: Add Share functionality for a category #86
Description
Provide functionality to have a user, that has full READ,WRITE,DELETE rights for it, share a category with another user or even make the category public. To be implemented:
- server endpoints
- UI elements and logic
Further details for this issue to come up - also wiremock needed
Rough idea:
- A user with "rwd"-rights (precondition) gets some button (?) in CategoryCard to share this category with others
- She can either declare it as "public" or enter (one or several) other user emails (free-text no suggestions due to privacy)
- then she provides the kind of access the public or user(s) should get (like READ only, RW or RWD) maybe we should start with only one user OR public -to k.i.s.s ?
- data are sent to backend, where user name is validated against user collection - and the request is either fulfilled or rejected, if user is not valid.
