Rails 5 yield gives duplicate contents - ruby-on-rails

I am figuring out why it showing duplicate data on the front page:
All I did is to use Rails collection rendering.
Here's my application.html.erb file:
<body>
<%= render 'layouts/navbar' %>
<!-- content -->
<main class="pt-5">
<div class="container">
<div class="row">
<%= render 'layouts/sidebar' %>
<%= yield %>
<%= render 'layouts/footer' %>
</div>
</main>
</body>
</html>
Here's my index.html.erb file:
<div class="col-md-9">
<% if #contacts.blank? %>
<div class="alert alert-warning">
<strong>Record is empty!</strong>
</div>
<% else %>
<div class="card">
<div class="card-header"><strong>All Contacts</strong></div>
<table class="table">
<%= render #contacts %>
</table>
</div>
</div>
<% end %>
and here's my _contact.html.erb file:
<% #contacts.each do |contact| %>
<tr>
<td class="middle">
<div class="media">
<div class="media-left">
<a href="#">
<%= image_tag contact.gravatar, class: "media-object" %>
</a>
</div>
<div class="media-body">
<h4 class="media-heading"><%= contact.name %></h4>
<address>
<strong><%= contact.address %>, <%= contact.city %>, <%= contact.state %>, <%= contact.zip %></strong><br>
<%= contact.email %> | <%= contact.phone %> | <%= contact.mobile %>
</address>
</div>
</div>
</td>
<td width="100" class="middle">
<div>
<a href="#" class="btn btn-outline-secondary btn-circle btn-xs" title="Edit">
<i class="fa fa-edit"></i>
</a>
<a href="#" class="btn btn-outline-danger btn-circle btn-xs" title="Delete">
<i class="fa fa-times"></i>
</a>
</div>
</td>
</tr>
<% end %>
BTW, I am using Kaminari Gem for pagination. It works however the data shows twice.
Any idea?
UPDATES:
Here's my contacts controller:
class ContactsController < ApplicationController
def index
#contacts = Contact.page params[:page]
end
end
Here's the kaminari config file:
# frozen_string_literal: true
Kaminari.configure do |config|
config.default_per_page = 2
# config.max_per_page = 4
# config.window = 4
# config.outer_window = 0
# config.left = 0
# config.right = 0
# config.page_method_name = :page
# config.param_name = :page
# config.params_on_first_page = false
end

When you do <%= render #contacts %>, Rails will loop results from #contacts and render each one using _contact.html.erb, while embedding local variable contact in each one. You see contacts twice, because you loop twice: remove <% #contacts.each do |contact| %> from _contact.html.erb and it should work.

Rails: Cannot get tabs to work with and kaminari

I have two tabs at the profile page: tab 1) my recipes, tab 2) my favorites.
Kaminari pagination works just fine when I go to the index page for recipes. However the pagination does not work properly at the profile page. When I click on next it does show me the next page, but the pagination bar disappears. So I cannot go back, unless I refresh the page.
Who can help me? Thank you in advance.

class ProfilesController < ApplicationController

#favorites = current_user.favorites.order("name").page(params[:favorites_page]).per(3)
end
end

Rails link a tags

I have the code below and I want to create an tag between the div with the class 'box'.
I cant just use the link_to method because I want this link to encompass all the html code from the to its respective ending . So anyone who clicks within that box gets transported to the equivalent of: <%= link_to( 'go', { action: :edit, id: course.id }) %>. I tried finding this else where but failed.
<% #courses.in_groups_of(3, false) do |group| %> <!--Takes groups of three courses -->
<div class="row">
<% group.each do |course| %>
<div class="col-xs-12 col-sm-6 col-lg-4">
<div class="box">
<div class="icon">
<div class="image"><span class="glyphicon glyphicon-list-alt btn-lg white"></span></div>
<div class="info">
<h3 class="title"><%= course.name %> | GPA: <%= course.gpa.to_f %></h3>
<p>
<%= course.description %>
</p>
<div class="more">
<a href="#" title="Title Link"><i class="fa fa-plus"></i> Details
</a>
<%= link_to( 'go', { action: :edit, id: course.id }) %>
</div>
</div>
</div>
<div class="space"></div>
</div>
</div>
<% end %>
</div>
<% end %>
<%= link_to({ action: :edit, id: course.id }) do %>
<div class="box">
<div class="icon">
<div class="image"><span class="glyphicon glyphicon-list-alt btn-lg white"></span></div>
<div class="info">
<h3 class="title"><%= course.name %> | GPA: <%= course.gpa.to_f %></h3>
<p>
<%= course.description %>
</p>
<div class="more">
<i class="fa fa-plus"></i> Details
</div>
</div>
</div>
<% end %>
I am not sure I understand your question, but I think you are asking to enclose your html code into a link_to tag. So try this:
<%= link_to path_to_land_on do %>
<div class='box'>
// other code
</div>
<% end %>
Replace path_to_land_on with { action: :edit, id: 2 } or path

favouriting users profiles in rails

so I've created a web app that has user profiles, where users can search for fellow users based on interests etc.. How might I add a feature where users can favorite a persons profile? I.e. User A finds User B and likes what they see, and can click a 'Favorite this profile' button and perhaps it's starred, and stored? What would the code look like for this? Just an idea, but I'm open to all ideas.

Create a Favorite model with a has_and_belongs_to_many relationship with User
Once you create the Favorite model and set up the relationship, you can do things like:
#user.favorites = [ user1, user2, user3 ]
#user.favorites << user4
to assign favorites to a user, or display them with something like:
<%= #user.favorites.map(&:name).to_sentence %>
You'll find everything you need to know on how to do this here: http://guides.rubyonrails.org/association_basics.html

Ability to only see the content of the profile that has been filled out

so I've created a web app that has user profiles, where users can search for fellow users based on interests etc.. However sometimes the users don't fill out certain areas of their profile, i.e. about me may be left blank.. So how can I add the ability for users to only see the content of the profile that they filled out. In other words they can’t see the parts of other user profiles for which they have not completed.

The conditionals that you have can be expanded to cover the whole div containing the info block.
For example:
<div class="addy">
<div class="span2">
<%# User address %>
<i class="fa fa-home"></i>:
<%= current_user.address.present? ? current_user.address : link_to('Add Address', edit_account_path) %>
</div>
</div>
Could be
<div class="addy">
<% if current_user.address.present? %>
<div class="span2">
<%# User address %>
<i class="fa fa-home"></i>:
<%= current_user.address %>
</div>
<% else %>
<%= link_to('Add Address', edit_account_path) %>
<% end %>
</div>
Then it would only show the link if the address is not present.
Seems like you're on the right track. Basically, for every user attribute on the User model you want to show/hide, you'll want to add a conditional that evaluates whether or not the attribute on current_user is present?:
<span class="name1">
<% if current_user.first_name.blank? %>
<%= link_to('Finish your profile', edit_account_path) %>
<% else %>
<%= current_user.first_name %> <%= current_user.last_name %>
<% end %>
</span>
Alternatively, you can continue using ternary operators for single line evaluations, as you are already doing in some instances:
<%= current_user.address.present? ? current_user.address : link_to('Add Address', edit_account_path) %>
