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 &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;\<% if blue\_widget.a == 0 and blue.widget == 1 %\> &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;...come code for second condition &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;\<% 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([http://api.rubyonrails.org/classes/ActionView/Helpers/DebugHelper.html](http://api.rubyonrails.org/classes/ActionView/Helpers/DebugHelper.html)) in your view to see the values. Maybe you forgot to set something. \<code\> &nbsp;&nbsp;debug(blue\_widget) \</code\>

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?

```ruby
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.
