    It is also possible to insert erb tags in INSERT mode (using rails.vim and surround.vim plugins):

    1. Press Ctrl + s and = afterwards to insert <%= %> block
    2. Press Ctrl + s and - afterwards to insert <% -%> block
    3. Press Ctrl + s and # afterwards to insert <%# %> block

    For surroundings in the erb views you might need Tim Pope's ragtag. It can handle different erb specific surroundings. Check out the documentation.

    I've been using the surround.vim plugin for a long time, but not the rails.vim plugin. Turns out that the rails.vim plugin is adding functionality to surround.vim, or is piggy-backing on it. Either way, I got it working this-a way:

    1. Install the rails.vim plugin if it isn't already, and open an ERB document. Vim should recognize it as a eruby filetype.
    2. If it doesn't use :set filetype=eruby Return to make Vim see things your way.
    3. Visually select some text you want to wrap with the ERB tags using v or V.
    4. Press S= or S-. (That's capital S)
    5. The selected text should be wrapped in a <%= %> or <%- %> block.

    I just confirmed this works in column-selection mode too.

    This is documented in the rails.vim help: from the command-mode search for :h rails-surround. And if you don't have the help available for rails.vim, it's because the instructions weren't followed for installing it:

    :helptags ~/.vim/doc
    

    The rails.vim plugin requires the surround.vim plugin also, so that has to be previously installed. I use that plugin's functionality at least once a minute when I'm editing. It rocks.
