hey

I am able to do:

```
 block_func(x, y) do
  ....
 end

```

But if I try to do this:

```
 form.block_func(x, y) do
  ....
 end

```

I get an error like this:

```
  syntax error, unexpected ')'
  @output_buffer.concat " "; @output_buffer.concat

```

(( form.block\_func(x, y) do ).to\_s);  
@output\_buffer.concat “\n”

Any ideas?

thanks

I should mention that I am making these functions myself… to use in  
a view

Is there something I need to do to get the function working as a model  
method in a “do” block?

some more context would be useful - at a basic level you don’t need to  
anything in particular to do this (eg when you’re calling fields\_for  
on a form builder). You might have used \<%= when you should have used \<%
