How would I get all people, that are following my in Ruby - ruby

I am using the act_as_follower gem, and I get all the users, that I follow, but now I want all the users, that are following me, how would I do that. I checked and I think something like this
current_user.followers, but I cant get it working. My code for people that I am following is this:
<% #users = User.all %>
<% #users.each do |user| %>
<% unless user == current_user %>
<div class="container people-lists list-following">
<%= image_tag("/assets/" + user.avatar + ".png", alt: "Logo", class: "people-image") %>
<%= user.username %>
<% if user_signed_in? %>
<% unless user == current_user %>
<% if current_user.following?(user) %>
<%= button_to("Un-Follow", user_follow_path(user.to_param, current_user.get_follow(user).id), :method => :delete, :remote => true, class: 'btn btn-primary button') %>
<% else %>
<%= button_to("Follow", user_follows_path(user.to_param), :remote => true, class: 'btn btn-primary button') %>
<% end %>
<% end %>
<% end %>
</div>
<% end %>
<% end %>

I found I the User.all returns all of them, and I can use the all_following, and follows like this and it works.
<% #users = current_user.all_following %>
And like this
<% #users = current_user.followers %>

First radio_button not showing in Rails 5

I'm using Devise within Rails 5 and have added Enum/roles (Consumer, Designer) to the User model. When creating a new registration, I want the user to select a role, for which I've added a radio_button for each value/role:
<div id="user_role"
<% User.roles.keys.each do |role| %>
<%= f.radio_button :role, role %>
<%= f.label role.to_sym %>
<% end %>
</div>
It's showing the labels of both roles, but only the radio_button for the last role. Here are the roles defined in the User model:
enum role: [:consumer, :designer]
Any ideas on what I'm doing wrong here?
try to this way
<div id="user_role">
<% User.roles.keys.each do |role| %>
<%= f.radio_button :role, role %>
<%= f.label role.to_sym %>
<% end %>
</div>
or
<div id="user_role">
<% User.roles.each do |role| %>
<%= f.radio_button :role, role %>
<%= f.label role[0] %>
<% end %>
</div>
it's working fine in my local.I hope it's will be help you.

cached votes not updating with validates_presence_of in model

I have acts_as_taggable installed and working for my products with cached votes.
After I tried to finish my validations inside the Product model with validates_presence_of the cached votes are not getting updated anymore.
Anyone had the same problem?
Any hint is appreciated.
Basic validation inside the product model. If this line is not there, the cached_votes work:
validates_presence_of :original_url, :format => URI::regexp(%w(http https))
How I trigger the votes:
<% if user_signed_in? %>
<% if current_user.liked? likeable %>
<%= form_tag unlike_path(likeable_type: likeable.class.to_s, likeable_id: likeable.id), method: :post, remote: true do %>
<% button_tag class: 'btn btn-block liked' do %>
<%= fa_icon 'heart-o' %> unlike
<% end %>
<% end %>
<% else %>
<%= form_tag like_path(likeable_type: likeable.class.to_s, likeable_id: likeable.id), remote: true do %>
<% button_tag class: 'btn btn-block' do %>
<%= fa_icon 'heart' %> like
<% end %>
<% end %>
<% end %>
<% else %>
<%= link_to new_user_registration_path do %>
<% button_tag class: 'btn btn-block' do %>
<%= fa_icon 'heart' %> like
<% end %>
<% end %>
<% end %>

Rails 4 Error: undefined method[]' for nil:NilClass`

I'm trying to setup a messaging system in my site using the Mailboxer gem in Rails 4.
When my app gets to this code:
def fetch_params(key, *subkeys)
params[key].instance_eval do
case subkeys.size
when 0 then self
when 1 then self[subkeys.first]
else subkeys.map{|k| self[k] }
end
end
it returns the error: undefined method '[]' for nil:NilClass
I've tried to figure this out, but I'm not very experienced. I've been following this tutorial: http://jamestansley.com/2014/02/22/customizing-the-mailboxer-ruby-gem-2/
I tried removing the line of code returning the error just to see what would happen, after which I received the error wrong number of arguments (1 for 2..6).
Can anyone attempt to explain this code to me? Been having a really rough time implementing this feature.
view/conversations/_form:
<%= simple_form_for :conversation, url: :conversations do |f| %>
<%= f.input :recipients %>
<%= f.input :subject %>
<%= f.input :body %>
<div class="form-actions">
<%= f.button :submit, class: 'btn-primary' %>
<%= submit_tag 'Cancel', type: :reset, class: 'btn btn-danger' %>
</div>
<% end %>
view/conversations/show:
<h1><%= #conversation.subject %> </h1>
<!--may have to work on this view. don't know if i did the haml conversion correctly-->
<h1> <%= conversation.subject %> </h1>
<ul>
<% content_tag_for(:li, conversation.receipts_for(current_user)) do |receipt| %>
<%= message = receipt.message %>
<h3><%= message.subject %> </h3>
<p><%= message.body %> </p>
</ul>
<% render 'messages/form', conversation: conversation %>
<% end %>
And here's my github repo: https://github.com/portOdin/GoFavorIt-Heroku/blob/8cd19ff5b61eb805dc694a6586f50df608752be2/app/views/conversations/show.erb

Ruby variable each loop substitution

I need to replace X_VARIABLE in 2 places.
For the first X_VARIABLE I want to keep the text 'remove'
For the second X_VARIABLE I want to keep 'd_cars_path'
<% #cars.each do |x| %>
<% #a = #b.send(x) %>
<% if #a == true %>
<%= button_to "removeX_VARIABLE", X_VARIABLEd_cars_path(:id => #user.id), class: "btn btn-large btn-primary" %>
<% end %>
<% end %>
I am looking for some help with the variable substitution syntax. Thanks.
I'd write:
<% #cars.each do |x| %>
<% if #b.send(x) %>
<%= button_to "remove#{x}",
send(:"#{x}d_cars_path", id: #user.id),
class: "btn btn-large btn-primary" %>
<% end %>
<% end %>

semantic_form_for with an alert upon completion

I am using semantic_form_for and I wonder if there is such attribute as :complete then upon successful creation, the form would alert something so that the user would have to click on "Okay" to proceed?
Do you mean confirmation before submit?
you could use something like the following:
<%= semantic_form_for #user do |f| %>
...
<%= f.buttons do %>
<%= f.commit_button :button_html => {:confirm => 'Are you sure?'} %>
<% end %>
<% end %>
My solution is like the following and it works well:
<%= semantic_form_for #post do |f| %>
...
<%= f.action :submit, :button_html => { 'data-confirm'.to_sym => 'Are you sure?' } %>
<% end %>
