Is there any way to use a link\_to method within a controller through a  
:flash notice? If a user enters an incorrect username/password, I want  
to have a link to a forgotten password form readily available.

My newbie attempt at doing this resulted in the following error:

undefined method `link\_to’ for #UserController:0x386aef8

I suppose I could easily have a normal link, was just wondering if there  
was a more correct way to do this.

Have you tried something like:

session[:flash] = “blah blah blah some text #(link\_to “my link”  
:controller =\> ‘hi’, :action =\> ‘there’} some more text”

I tweaked that a little to get rid of the syntax errors to be:  
flash[:notice] = “blah blah blah some text #{link\_to ‘my link’,  
:controller =\> ‘hi’, :action =\> ‘there’} some more text”

The same error appears though. Even simplifying the whole thing down to:  
flash[:notice] = link\_to ‘my link’, :controller =\> ‘hi’, :action =\>  
‘there’

Still throws the same error…

Managed to work this one out. For anyone that comes across this in the  
future, use url\_for, eg: url\_for :controller =\> ‘user’, :action =\> ‘new’

The full line is below, not sure if this will display correctly:

flash[:notice] = “\<a href=”"#{url\_for :controller =\> ‘user’, :action =\>  
‘new’}""\>test"
