Hi,

I have a list of things in my application (let it be list with something  
to borrow).  
I wanted to change in css and view something.

I wanted to see row with has one field empty (let us say it will be  
given back date) in different color(red or something)

Fragement of my view …

\<% for list in @lists -%\>

\<%=h list.id -%\>) \<%=h list.title %\> \<%=h list.body %\> \<%=h list.char %\> \<%=h list.sim %\> \<%=h list.oth %\> \<%=h list.wyp %\> \<%=h list.od %\> \<%=h list.comm %\> \<% end %\>

and CSS

.list-line-even {  
background: #f8b0f8 ;  
}

that changing color of my list view perfectly i wonder how to add this  
feature

if some empty field is in row class is being changed do different…

I thought about :

\<% for list in @lists -%\>

\<% if list.od = ''-%\> \<%=h list.id -%\>) \<%=h list.title %\> \<%=h list.body %\> \<%=h list.char %\> \<%=h list.sim %\> \<%=h list.oth %\> \<%=h list.wyp %\> \<%=h list.od %\> \<%=h list.comm %\> \<% end %\>

and CSS

.list-line-even1 {  
background: #f8b0f8 ;  
}

.list-line-even {  
background: #fff ;  
}

that changig color of my list view perfectly i wonder how to add this  
feature

if some empty field is in row class is being changed do different…

So you want to be able to set a differnt style to cells that are empty.  
You can do something like:

In the view:  
\<td\<%= ’ class=“empty”’ if(list.commm.blank?) %\>\>  
\<%=h list.comm %\>

In the css:

.list-line-even.empty, .list-line-even1.empty {  
color: #F00;  
}

Just a quick question: why are you using \<% %\> with a literal string?  
Since the value of the string will never change, you don’t need the \<%  
%\>.

(And you really should try Haml instead of ERb.)
