I got this Rails blogs app and for the indexpage where the articles are posted it shows a short version of the article.
<%= render 'layouts/header' %>
<%= render 'layouts/topbar' %>
<div class="contentnews">
<%= render 'layouts/bannerad' %>
<div class="row">
<% if current_user.try(:admin?) %>
<%= link_to 'Nieuws toevoegen', new_article_path, :class => "button ala" %>
<% end %>
</div>
<div class="row">
<%= render 'overview' %>
</div>
</div>
The overview-partial :
<div class="articlebox ">
<div class="large-4 columns">
<% #articles.reverse_each do |article| %>
<div class="articlebox2">
<div class="articleindex">
<%= link_to article.title, article %>
</div>
<div class="articlebody">
<%= article.short.to_s.html_safe %>
</div>
</div>
<% end %>
</div>
</div>
The problem is that this way all the articles end up in one row. I want it to show the short articles inline on the page and after every two or three article it has to start in a new row with again two or three short articles.
Anybody got any idea?
You don't actually need to create a row every n-elements. With foundation just wrap all the elements in a row, and give them columns class:
<div class="articlebox">
<div class="large-4 columns">
<div class="row"> <!-- Wrap in a row -->
<% #articles.reverse_each do |article| %>
<div class="articlebox2 large-6 columns"> <!-- Give a column and width class here -->
...
</div>
<% end %>
</div>
So you can nesting grids with foundation, and creating new rows is not necessary, foundation will just wrap if the elements exceeds the grid.
If you actually really want to create rows, you can have a look at the method each_with_index API and then insert row elements if index % 2 == 0. But this is unnecessary complexity.

Please help me to resolve this error.
Error is self explanatory.
NoMethodError in Sessions#loginadmin
undefined method `errors' for nil:NilClass
You are getting this error because #admin is nil and you are calling errors method on a nil object..
If you look loginadmin action is sessions controller you are rendering 'index' template when there is no #admin object, which is causing this error.
Fix:
Either create separate templates for both these actions with common code in partials or simply use rails try method which returns nil rather than raising an exception
<% if #admin.try(:errors).try(:any?) %>
OR
Just use a condition at top to separate out error code:
<% if #admin %>
<div class="error-div">
<% if #admin.errors.any? %>
<div id="error_explanation">
<h2><%= pluralize(#admin.errors.count, "error") %> prohibited this post from being saved:</h2>
<ul>
<% #admin.errors.full_messages.each do |msg| %>
<li><%= msg %></li>
<% end %>
</ul>
</div>
<% end %>
</div>
<% end %>
P.S I would recommend you to use different templates with common code separated in partials.
when I submitted the form, the new data don't save in database and as a result I can not see them, but when I make a new data like welcome= Welcome.new and welcome.title="your are" by rails console they work and I can only see things that I have made in console not by application. It seems submit bottom doesnt save any data.

end
end

def user_params
params.require(:welcome).permit(:kind, :title, :text)
end
Your form is not submitting to the right route. Use form builder instead:
<%= form_for #welcome do |f| %>
<%= f.label :kind %>
<%= f.text_field :kind %>
<%= f.submit %>
<% end %>
This will put right route for form submission into your HTML

Am using kaminari ajax pagination in my project. It is working fine, But contents are displaying number of pages times in the page. For example if number of items per pages is 7, then it is displaying 7 times the same content. What am doing is

Please help me to solve this problem
I noticed that when i use <%= render #products %> how many items i have taken per page that number of times it repeates. Therefore I solved this by the following code:
In product_details controller
def index
#products=ProductDetail.where("department_id = ? and category_id = ?",1, 1).page(params[:page]).per(15)
end
In product_details/home.html.erb
<div id="product_details">
<%= render 'index' %>
</div>
In product_details/index.js.erb
$('#product_details').html('<%= escape_javascript render ('index') %>');
In product_details/_index.html.erb
<div id="product_list">
<%= paginate #products, :remote=>true %>
<% #products.each do | product | %>
<div class="product_container">
<div class="product_box" >
<div id="future_image_container">
<div class="image_block" >
<%= image_tag(product.image_path, :alt => "product image", :height=>"215px") %>
</div>
<span id="future_price" style="text-decoration: line-through; color: #9e9c9c;">
<span style="color: black;">
<%= "$#{product.price}" %>
</span>
</span>
<div id="circle">
<p>
<% if(product.discount > 0) %>
<% new_price=((2.0*((product.price*product.discount)/100)).round)/2.0 %>
<% else %>
<% new_price=product.price %>
<% end %>
<%= "$#{new_price}"%>
</p>
</div>
</div>
<p class="future_product_name">
<%= product.name %>
</p>
<% #brands=Brand.where("id=?",product.brand_id)
#brands.each do |brand|
#brandname=brand.name
end
%>
<p class="future_product_name">
<%= "Brand : #{#brandname}" %>
</p>
</div>
</div>
<% end %>
</div>
Now no product repeates and ajax pagination is also working fine
