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 -%> <tr class="<%= 'list-line-even' -%>" > <td><%=h list.id -%>)</td> <td><%=h list.title %></td> <td><%=h list.body %></td> <td><%=h list.char %></td> <td><%=h list.sim %></td> <td><%=h list.oth %></td> <td><%=h list.wyp %></td> <td><%=h list.od %></td> <td><%=h list.comm %></td> <% 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 -%> <tr class="<%= 'list-line-even1' -%>" > <% if list.od = ''-%> <tr class="<%= 'list-line-even' -%>" >

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

In the css:

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

Sorry i need to add another question how to make it that way that i have 2 css defined ?

I mean:

<% for list in @lists -%> <tr class="<%= 'list-line-even' -%>" > <tr class="<%= 'list-line-even1' if list.od.blank? -%>" > .... <td><%=h list.id -%>)</td> <td><%=h list.title %></td> <td><%=h list.body %></td> <td><%=h list.char %></td> <td><%=h list.sim %></td> <td><%=h list.oth %></td> <td><%=h list.wyp %></td> <td><%=h list.od %></td> <td><%=h list.comm %></td>

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.)

Best,
