I am having trouble with what I thought would be a simple equality  
comparison.

Here is the relevant code:

\<% for ticket in @tickets %\>

 \<% for column in Ticket.content\_columns %\> \<% if column.human\_name == "Status" %\> \<% if ticket.send(column.name).eql?("true") %\> Open \<% else %\> Closed \<% end %\> \<% else %\> \<%=h ticket.send(column.name) %\> \<% end %\> \<% end %\>

My problem is as follows:

if ticket.send(column.name).eql?(“true”) always evaluates to false and  
prints Closed.

I’ve also tried:  
if ticket.send(column.name) == “true” but I get the same behavior.

When I try \<%=h ticket.send(column.name) %\> it get true

Any help would be most appreciated.

Try this

```
  <% if column.human_name == "Status" %>
   <% if ticket.Status == "true" %>
    <td>Open</td>

```

That would work too, and be a lot cleaner.

Thanks!

Nevermind my bad. Passing true to eql? in the proper way fixed my  
problem.

However anyone know why == “true” wouldn’t work when the same form  
works for checking the column name against “Status”?

I haven’t tested this, but I’m gonna guess that Ticket.status is a  
boolean  
field, but you’re comparing it to the _string_ “true”. What happens if  
you do:

ticket.send(column.name).eql?(true)

?

“true” is the string with the letters t,r, u and e. Not in anyway  
related to the boolean value true (except in the way that anything non  
nil is true in ruby. the column’s name is however just a string.

> if ticket.send(column.name)

would be enough
