Hello,

I have a problem with link\_to, this is my code

\<%  
if @categories  
for category in @categories  
link\_to “test”, “[http://www.rubyonrails.org/](http://www.rubyonrails.org/)”  
end  
end  
%\>

But this doesn’t output anything to the screen, but with the below code,  
it output the text inside the block.

\<%  
if @categories  
for category in @categories  
%\>test \<%  
end  
end  
%\>

I’m using link\_to in the wrong way or ???

Hope someone can help me out, and thanks 🙂

Hi Jamal,

You need to use link\_to like this:  
\<%= link\_to “test”, “[http://www.rubyonrails.org/](http://www.rubyonrails.org/)” %\>

instead of what you are doing:  
\<% link\_to “test”, “[http://www.rubyonrails.org/](http://www.rubyonrails.org/)” %\>

In your example you could do the following:  
\<%  
if @categories  
for category in @categories %\>  
\<%= link\_to “test”, “[http://www.rubyonrails.org/](http://www.rubyonrails.org/)” %\>  
\<% end  
end  
%\>

or

\<%  
if @categories  
for category in @categories  
puts link\_to “test”, “[http://www.rubyonrails.org/](http://www.rubyonrails.org/)”  
end  
end  
%\>

HTH,

Mischa

I would like to use the “puts” =\> but it doesn’t output anything? The =  
is working good but I don’t like to open and close %\> all the time if I  
need to use \<%=

You’re right “puts” doesn’t work.

One suggestion – to make it look more clean – is that you make sure in  
the controller that @categories is not nil (instead of in the view). If  
you do that the code in your view could look like this:

\<% for category in @categories -%\>  
\<%= link\_to “test”, “[http://www.rubyonrails.org/](http://www.rubyonrails.org/)” %\>  
\<% end -%\>

Cheers,
