I am working on a project and currently working on one of the views which is a page of different categories. Everything is rendering correctly however it's also putting the db info in the page.
Here is the code of my view
<div class="categories">
<div class="container blurbs">
<div class="cards row">
<%= @categories.each do |c| %>
<div class="card col-xs-4" %>
<%= image_tag c.image, :class => "cat" %>
<h4 class="title"><%= c.title %></h4>
</div>
<% end %>
</div>
</div>
</div>
Here is a link to a screenshot of rendered page
Yes, fix is:
<div class="categories">
<div class="container blurbs">
<div class="cards row">
<% @categories.each do |c| %>
<div class="card col-xs-4" %>
<%= image_tag c.image, :class => "cat" %>
<h4 class="title"><%= c.title %></h4>
</div>
<% end %>
</div>
</div>
</div>
Look I removed =
from this <%=
.. In the below line :
<% @categories.each do |c| %>
#each
method returns the collection after it completed its iterations. And due to this <%=
, the return value of each
which is @categories
printed back. But if you use <%..
only, all above things will happen, but it wouldn't print back the object @categories
.
when you use the tags <%= ... %>
whatever is within the tags gets displayed on the page. In your current view you have
<%= @categories.each do |c| %>
<div class="card col-xs-4" %>
<%= image_tag c.image, :class => "cat" %>
<h4 class="title"><%= c.title %></h4>
</div>
<% end %>
Which displays the entirety of whatever the loop returns which is where you're getting the display. Change the tags to be <% @categories.each do |c| %>
<% @categories.each do |c| %>
and you'll be good to go.
