Hi  
In the view I have  
\<%= error\_messages\_for :problem%\>  
In the model I have validations. and in controller inside transaction  
I have

@problem.save! So suppose an error happens I have redirected to the  
same view which contains error\_messages …But my problem is I dont ge  
the error messages when redirect but get it when render the same

redirect\_to :action =\> ‘create\_ui’ #This dies not give error messages  
for problem  
render :action =\> ‘create\_ui’ #This gives error messages for problem  
Why this happens ?Please help

Sijo

Because the state of the invalid object is lost when you do a redirect  
(which is why people typically don’t do a redirect)

Hi

Thanks for the reply.Why I used the redirect because I first used render  
But In the view I have some check boxes One of them like  
\<%= select( “problem”, “problem\_urgency\_id”,  
ProblemUrgency.find(:all).collect {|p| [p.name, p.id] },options  
={:prompt =\> “\<\< Select any \>\>”}) %\>

```
So in the above if I use render(if error happens) what happens is 

```

that  
\<\< Select any \>\> is not shown and only the values from the  
problem\_urgencies table are shown That is why I used the redirect\_to  
But it has this problem(Not problem actually)…Could you please suggest  
how I can solve this?

Thanks in advance  
Sijo
