I need show a list of products in a carousel using bootstrap grouped by 4 elements in each 'item' class.
here is my develop
<div class="carousel-inner" role="listbox">
<% products.each_with_index do |product, n| %>
<% if n % 4 == 0 %>
<div class="item <%= 'active' if n == 0 %>">
<% end %>
<div class="col-lg-3 col-md-3 col-sm-3 col-xs-3">
...
</div>
<% if n % 4 != 0 %>
</div>
<% end %>
<%end%>
</div>
the problem is when i try close 'item' class. I can't catch the opposite of multiples of 4.
<div class="carousel-inner" role="listbox">
<% products.each_slice(4).with_index do |slice, index| %>
<div class="item <%= 'active' if index == 0 %>">
<% slice.each do |product| %>
<div class="col-lg-3 col-md-3 col-sm-3 col-xs-3">
...
</div>
<% end %>
</div>
<% end %>
</div>

Rails has truncate text helper:
<%= truncate post.description, length: 250 %>
I'm new to Rails and I'm trying to build a nice application and I'm struggling with arrays, I have 4 arrays that I want to iterate and they are not the same size
I want to generate sections in HTML using the first array what I did it
#sections = ['Section One','Section Two','Section Three','Section Four']
#itemsOne = ['item 1','item 2','item 3','item 4','item 5','item 6']
#itemsTwo = ['item 1','item 2','item 3','item 4','item 5','item 6']
I was using
<%= #sections.zip(#itemsOne, #itemsTwo).each do |t1, t2, t3| %>
<%= t1 %>
<table>
<tbody>
<tr>
<td>
<%= t2 %> | <%= t3 %>
</td>
<td>
<%= t2 %> | <%= t3 %>
</td>
<td>
<%= t2 %> | <%= t3 %>
</td>
</tr>
</tbody>
</table>
<% end %>
I have a table that have a Section Title and cells that have two values
but what I get is the value of |t2| in each cell of |t1| section
using #Phil answer down below, but he deleted it.
<%= #sections.zip(#itemsOne, #itemsTwo).each do |t| %>
<%= t[0] %>
<table>
<tbody>
<tr>
<td>
<%= t[1] %> | <%= t[2] %>
</td>
<td>
<%= t[1] %> | <%= t[2] %>
</td>
<td>
<%= t[1] %> | <%= t[2] %>
</td>
</tr>
</tbody>
</table>
<% end %>
p.s. the itemsOne and itemsTwo arrays have more than 20 values.
What I created is separated my big arrays into smaller ones and then Iterated thru each this way without a Table because table was making design issues so i went into div's using bootstrap 3 column, there might be a better way but this is what i got as a beginner.
<div class="row">
<div class="col-md-12">
<h4><%= #Sections[0] %></h4>
<!-- This will Display Section 0 in the Array -->
</div>
<div class="row">
<div class="col-md-12">
<% #count = 0 %>
<!-- Counter is Zero -->
<% #ItemsOne.collect do |t1| %>
<!-- This will loop array to increment the #count and repeat the HTML -->
<% #count += 1 %>
<!-- With each loop increment by 1-->
<div class="col-md-3">
<div class="col-md-12">
<label>
<input type="checkbox" name="optionsCheckboxes">
<%= #ItemsOne[#count - 1] %>
<!-- Counter should start from 0 adding -1 will make it start
from 0 instead of 1 and then will print the value of the Index Number -->
</label>
</div>
</div>
<% end %>
</div>
</div>
</div>
Here is another way to do this
<div class="row">
<% #Sections.each_with_index do |x1, n| %>
<div class="row">
<div class="col-md-12">
<h4><%= #Sections[n] %></h4>
</div>
<div class="row">
<div class="col-md-12">
<% if n == 0 %>
<% #itemsOne.each_with_index do |t1, n| %>
<div class="col-md-3">
<div class="col-md-12">
<label>
<input type="checkbox" name="optionsCheckboxes">
<%= #itemsOne[n] %>
</label>
</div>
</div>
<% end %>
<% elsif n == 1 %>
<% #itemsTwo.each_with_index do |t1, n| %>
<div class="col-md-3">
<div class="col-md-12">
<label>
<input type="checkbox" name="optionsCheckboxes">
<%= #itemsTwo[n] %>
</label>
</div>
</div>
<% end %>
<% elsif n == 2 %>
<% #itemsThree.each_with_index do |t1, n| %>
<div class="col-md-3">
<div class="col-md-12">
<label>
<input type="checkbox" name="optionsCheckboxes">
<%= #itemsThree[n] %>
</label>
</div>
</div>
<% end %>
<% elsif n == 3 %>
<% #itemsFour.each_with_index do |t1, n| %>
<div class="col-md-3">
<div class="col-md-12">
<label>
<input type="checkbox" name="optionsCheckboxes">
<%= #itemsFour[n] %>
</label>
</div>
</div>
<% end %>
<% end %>
</div>
</div>

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.

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
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) %>
