How to add Follow Me link inside content type in Drupal 7 My project contains two content types:- Professor and Lecturer.
Here the users are student so students can log in using their own credentials.

Now I want to show up a button/link with Text "Follow Me" in Professor &amp; Lecturer Content Type.When User/student will select the link/button then the corresponding Lecturer/Professor will be attached to the student profile and will be visible inside their home page. Similarly that student will be visible in Teacher/Lecturer.

I look at The "Relation" Module in Drupal 7 but my use case don't need to display too many things in the widget. There should be a simple button/link which relate user and content type.
You should try the Flag module for this. It should solve your purpose.


  Flag is a flexible flagging system that is completely customizable by the administrator. Using this module, the site administrator can provide any number of flags for nodes, comments, users, and any other type of entity. Some possibilities include bookmarks, marking important, friends, or flag as offensive. With extensive views integration, you can create custom lists of popular content or keep tabs on important content.
