How to setup the follow/unfollow/block link_to button for Acts_As_Follower Rails 4

I’m currently in the process of completing the setup for the
acts_as_follower gem for Rails 4. When I click on the follow button, the
ActionView Exception Missing Template kicks in. Does anyone know how to
create a multi-state Zurb Foundation button for it or even custom radius
button. Simply: “Follow/Unfollow” If you have a better approach, please
share it. These solutions are necessities to development.

<%= link_to ‘Follow’, follow_user_path(@user), class: ‘button success

def follow
@user = User.friendly.find(params[:id])
if current_user
if current_user == @user
flash[:error] = ‘You cannot follow yourself.’

current_user.follow(@user)
flash[:notice] = “You are now following #{@user.username}”
end
else
flash[:error] = “You must be logged in to follow
#{@user.username}.”
redirect_to :back
end
end

def unfollow
@user = User.friendly.find(params[:id])
if current_user
current_user.stop_following(@user)
flash[:notice] = “You are no longer following #{@user.username}.”
else
flash[:error] = “You must be logged in to unfollow
#{@user.username}.”
redirect_to user_path(@user)
end
end

def block
@user = User.friendly.find(params[:id])
if current_user
current_user.block(@user)
flash[:notice] = “You have blocked #{@user.username}.”
redirect_to user_path(@user)
else
flash[:notice] = “You aren’t following #{@user.username}.”
end
end

If you created an AJAX solution with the buttons before? Please post the
snippets while explaining your best practice approach.

Please post the output of rake routes in your terminal here. It appears
as though the gem should be hooking in a route to handle the click, but
your Rails app didn’t pick it up. Also, did you restart your app after
adding the gem and running bundle install?

A message shows you aren’t currently following constantly.

I’m using the latest version of Acts_As_Follower Gem. Can you help me
structure the solution better. Thanks

Woops, clicked enter by mistake.

The error comes because it’s looking for a file follow.html.erb in
your
app/views// directory. In your follow method, you do not
direct it anywhere, or tell it to render any other view, so that’s what
it’s looking for. Did you want it to go somewhere else?

def follow

#{@user.username}."
redirect_to :back
end
end

The only redirect in that method happens if there is no logged in user.
The
rest of it sets the flash, then falls through to the standard render.

By convention, a controller action will render a template with the same
name as the action plus the format extension (html in this case) and
handlers.

Initially you wanted to use a link_to to display the link someone
would
click on to indicate they wanted to follow someone.

<%= link_to ‘Follow’, follow_user_path(@user), class: 'button success

radius small’ %>

You’ll need to change this into an AJAX request rather than a link_to.
You
could probably use button_tag but you’ll still need to write the
actual
AJAX JavaScript code yourself for it. It’s pretty straight-forward in
jQuery, attaching a callback to the click event on the button, and the
callback function does the AJAX request.

On the server side, if you really wish to render nothing at all, render nothing: true will do that. See <
http://guides.rubyonrails.org/layouts_and_rendering.html#using-render>.

Thank you, Tamouse.

I’m in need of the AJAX method that allows a person to follow without
rendering a view.

In your link_to declaration, add remote: true in the options, and in
your controller, add a handler for format.js alongside the format.html
in the respond_to block. In that handler’s block, tell it what to do.
The simplest thing is to render a follow.js.erb, which can contain any
JavaScript you like to note to the user that the follow event happened.
Change the text of the button to “Following” for example. Add and remove
a CSS class to “flash” the button or whatever else makes sense to your
users.
