Hi there ,

I found the specific bug in my code. Truly saying I still did not find  
the bug . so I am writing now.

I am looping through database records in my view

\<% for blue\_widget in @blue\_widgets %\>

\<% if blue\_widget.B == 1 and blue\_widget.B == 1 %\>  
…some code  
\<% if blue\_widget.a == 0 and blue.widget == 1 %\>  
…come code for second condition  
\<% end %\>  
\<% else %\>  
…code for rest cases  
\<% end %\>

\<% end %\>

The question in way all of records do the ELSE condition despite of  
fact they should do the first or second IF ?  
Is the problem that I can not loop through the arrays in this way?

Best regards ,

Pg

Try to use the  
DebugHelper([ActionView::Helpers::DebugHelper](http://api.rubyonrails.org/classes/ActionView/Helpers/DebugHelper.html))  
in your view to see the values. Maybe you forgot to set something.  
`
debug(blue_widget)
`

Great tool, but I did not forget about anything

Considering content output of Debug() , the record should work with  
following condition  
\<% if blue\_widget.B == 1 and blue\_widget.B == 1 %\>  
…some code

But works with  
\<% else %\>  
…code for rest cases

Maybe , I did something wrong with if/else conditional statements?

Are you sure that the values are actually integers and not strings? Does  
this fix your problem?

blue\_widget.B.to\_i == 1 and blue\_widget.B.to\_i == 1

Are those the actual lines in your code, or typos from preparing your  
post?  
The first line is redundant, and the last line refers to a blue  
object, not a blue\_widget.
