This is my code:
<div class="column">
<div class="post-module">
<a href="https://www.livescience.com/59802-should-we-fear-
intelligent-robots.html" >
<div class="thumbnail">
<div class="date">
<div class="day">14</div>
<div class="month">Jul</div>
</div>
<img src="#"/>
</div>
<div class="post-content">
<div class="category">Robots</div>
<h1 class="title">Should We Fear The Rise of Intelligent
Robots? </h1>
<h2 class="sub_title"> Robots will unite. </h2>
<p class="description"></p>
</div>
</a>
</div>
</div>
I want to make that code in rails but I am just a beginner in rails and I wasn't able to find something that could help me in this. I only know the basic idea of the link_to in rails.
link_to method can take a block and display it's evaluation as a link content:
<%= link_to "https://www.livescience.com/59802-should-we-fear-intelligent-
robots.html" do %>
<div class="thumbnail">
<div class="date">
<div class="day">14</div>
<div class="month">Jul</div>
</div><img src="#"/>
</div>
<div class="post-content">
<div class="category">Robots</div>
<h1 class="title">Should We Fear The Rise of
Intelligent Robots? </h1>
<h2 class="sub_title"> Robots will unite. </h2>
<p class="description"></p>
</div>

I'm not sure where put the start and end of my iteration
Im using bootstrap frame work and its supposed to look like this
what bootstrap looks like
<div class="row row-cols-1 row-cols-md-3">
<div class="col mb-4">
<div class="card h-100">
<img src="..." class="card-img-top" alt="...">
<div class="card-body">

<p class="card-text">This is a longer card with supporting text below as a natural lead-in to additional content. This content is a little bit longer.</p>
</div>
</div>
</div>
This is what mine looks like
what mine loos like
<div class="row row-cols-1 row-cols-md-3">
<% #apparels.each do |apparel| %>
<div class="col mb-4">
<div class="card h-100">
<%= image_tag apparel.picture, class: 'card-img-top', width: 300 if apparel.picture.attached?%>

<p class="card-text">Size: <%= apparel.size %><br>$<%= apparel.price %></p>
</div>
</div>
</div>
<% end %>
</div>
Not sure what I'm doing wrong
Since you want each 3 boxes per-row, you can change line 3 to col-md-4, total each column is 12, so 12/4 = 3 it will automatically moving to next row
<div class="row row-cols-1 row-cols-md-3">
<% #apparels.each do |apparel| %>
<div class="col-md-4">
<div class="card h-100">
<%= image_tag apparel.picture, class: 'card-img-top', width: 300 if apparel.picture.attached?%>
<div class="card-body">
<h5 class="card-title"> <%= apparel.brand %> <%= apparel.model %></h5>
<p class="card-text">Size: <%= apparel.size %><br>$<%= apparel.price %></p>
</div>
</div>
</div>
<% end %>
</div>
I need to make a grid, using rails loop. It should look like this:
Usually, without rails loop, I would do it like this:
<div class="row">
<div class="col-lg-6"></div>
<div class="col-lg-6">
<div class="row">
<div class="col-lg-12"></div>
<div class="col-lg-12"></div>
</div>
</div>
</div>
But I need to show in that grid my tips objects:
<% #tips.limit(3).each do |tip| %>
<%= tip.title %>
<% end %>
as an example.
So, what is the best way to do it? Thanks in advance.
EDIT:
Just did like this, but I don't know, whether it is a right decision:
<div class="row">
<div class="col-lg-6">
<div class="tip-big">
<p><%= #tips[0].title %></p>
</div>
</div>
<div class="col-lg-6">
<div class="row">
<div class="col-lg-12">
<div class="tip-medium">
<p><%= #tips[1].title %></p>
</div>
</div>
<div class="col-lg-12">
<div class="tip-medium">
<p><%= #tips[2].title %></p>
</div>
</div>
</div>
</div>
</div>
I'm trying to create a two column layout. The first side should span 9 columns and the next one 3. Inside the col-md-9 I want to nest two more columns, one that spans 4 and another one that spans 8.
<div class="row">
<% #huddles.each do |huddle| %>
<div class="col-md-9">
<div class="row">
<div class="col-md-4">
<img class="img-responsive" src="http://placehold.it/300x150">
</div>
<div class="col-md-8">
<h4><%= huddle.title %></h4>
<h4 class="huddle-description"><%= huddle.description %></h4>
<%= link_to "Read More...", huddle_path(huddle) %>
</div>
</div>
<% end %>
</div>
<div class="col-md-3">Second Column</div>
</div>
This however, comes out looking like this:
Am I nesting my rows and columns wrong? Or maybe it is my ruby code itself that screws up the layout once new "Huddles" are created?
EDIT: With the fixed code, the second column "col-md-3" comes out next to the last created huddle. Inspecting it, all the huddles make one single row.
<div class="row">
<% #huddles.each do |huddle| %>
<div class="col-md-9">
<div class="row">
<div class="col-md-4">
<img class="img-responsive" src="http://placehold.it/300x150">
</div>
<div class="col-md-8">
<h4><%= huddle.title %></h4>
<h4 class="huddle-description"><%= huddle.description %></h4>
<%= link_to "Read More...", huddle_path(huddle) %>
</div>
</div>
</div>
<% end %>
<div class="col-md-3">Second Column</div>
</div>
And looks like this, where the second column moves all the way down next to the last huddle created:
I think this is what you are going for. I am pretty confident the issue is with the html structure and has nothing to do with ruby.
I also want to clarify. The initial issue you were having was that you were starting a div inside the loop but only closing it outside the loop. So starting n amount of divs but only one closing tag, and that would cause it to look like the image you first posted.
<div class="row">
<div class="col-md-9">
<% #huddles.each do |huddle| %>
<div class="show-region" >
<div class="col-md-4" style="height:150px;">
<img class="img-responsive" src="http://placehold.it/300x150">
</div>
<div class="col-md-8" style="height:150px;">
<h4><%= huddle.title %></h4>
<h4 class="huddle-description"><%= huddle.description %></h4>
<%= link_to "Read More...", subjects_path(huddle) %>
</div>
</div>
<% end %>
</div>
<div class="col-md-3">Second Column</div>
</div>
so I'm trying to show some blog-type data on one of my pages. It works fine, but is posting the posts all at the end of the div as well.
Like this:
Image
<div class="style-2 mb-20 shadow bordered light-gray-bg news-margin col-md-5">
<!-- page-title start -->
<!-- ================ -->
<h1 class="page-title">Latest News</h1>
<div class="separator-2"></div>
<!-- page-title end -->
<p class="lead">The latest news will be posted here:</p>
<div class="row grid-space-12">
<%=# news.each do |news| %>
<div class="col-sm-12">
<div class="image-box style-2 mb-20 shadow bordered text-center">
<div class="overlay-container">
<i class="fa fa-newspaper-o fa-5x p-20"></i>
<div class="overlay-to-top">
<p class="small margin-clear"><em> <%= news.topic %> <br> <%= news.created_at.strftime("%A, %b %d") %></em>
</p>
</div>
</div>
<div class="body">
<h3><%= news.header %></h3>
<div class="separator"></div>
<p>
<%=n ews.content %>
</p>
Read More<i class="fa fa-arrow-right pl-10"></i>
</div>
</div>
</div>
<% end %>
</div>
</div>
Figured it out, I had the = in with <%= news.each do |news| %>, which was printing that info out...
I am working within a Ruby on Rails app. I have a loop that creates divs like this:
<% #snorks.each do |snork| -%>
<div>
<%= snork %>
</div>
<% end %>
And I need the output to have every other div be floated left or right like this:
<div class="left">
Allstar Seaworthy
</div>
<div class="right">
Casey Kelp
</div>
<div class="left">
Dimmy Finster
</div>
<div class="right">
Daffney Gillfin
</div>
<div class="left">
Tooter Shellby
</div>
<div class="right">
Dr. / Uncle Galeo
</div>
Additionally, I need to add a div with class="clear" every two divs, like this:
<div class="left">
Allstar Seaworthy
</div>
<div class="right">
Casey Kelp
</div>
<div class="clear"></div>
<div class="left">
Dimmy Finster
</div>
<div class="right">
Daffney Gillfin
</div>
<div class="clear"></div>
<div class="left">
Tooter Shellby
</div>
<div class="right">
Dr. / Uncle Galeo
</div>
<div class="clear"></div>
I have researched, and found a few posts saying that the alternate classes can be accomplished easily by using cycle(), and that does work. However, when I use it in two places within the loop it stops working right and just outputs something like this:
<div class="left">
Allstar Seaworthy
</div>
<div class="left">
Casey Kelp
</div>
<div class="left">
Dimmy Finster
</div>
<div class="left">
Daffney Gillfin
</div>
<div class="left">
Tooter Shellby
</div>
<div class="left">
Dr. / Uncle Galeo
</div>
What's the best practices way in Ruby on Rails to alternate classes in a loop, and also add something every other loop?
According to the documentation, if you need nested ones you name them. Otherwise they will both share the name "default" and conflict.
<% #snorks.each do |snork| -%>
<div class="<%= cycle('left', 'right') -%>">
<%= snork %>
</div>
<%= cycle('','<div class="clear"></div>', :name=>"cleardiv") %>
<% end %>
The best thing here seems to be using each with index. That way you could do some simple modulus math to determine if the number is odd or even and output the correct class and add the clears.
#snorks.each_with_index do | snork, index|
If index%2 == 0
class = 'left'
else
class = 'right'
end
Well u get my drift and I'm on my phone.
use cycle helper
http://apidock.com/rails/ActionView/Helpers/TextHelper/cycle
<% #snorks.each do |snork| -%>
<div class="<%= cycle("left", "right") -%>">
<%= snork %>
</div>
<% end %>
Edit: for adding new div; following could help
<% #snorks.each_slice(2) do |snork_batch| -%>
<% snork_batch.each do |snork|%>
<div class="<%= cycle("left", "right",:name=>"className") -%>">
<%= snork %>
</div>
<%end%>
<div class="clear"></div>
<% reset_cycle("className")%>
<% end %>
