Since updated edge yesturday i have had a series of errors related to  
undefinded methods for “products”:String.

I do have these controllers namespaced.

====  
Errors example 1:  
undefined method `request’ for “products”:String  
Extracted source (around line #2):

view:

  
\<%= render :partial =\> ‘admin/products/product’, :collection =\>  
@collection %\>  

view parital  
\_product

1:

  
ERROR HERE\> 2: \<%= image\_tag( product.cover(:thumb\_50), :class =\>  
‘image’ ) if product.cover(:thumb\_50) %\>

model:  
class Product …  
.  
.  
def cover(size)  
assets.blank? ? nil : assets.first.public\_filename(size)  
end

===  
Errors example 2:  
undefined method `url\_for’ for “categories”:String  
Extracted source (around line #10):

helper

def link\_to\_orderable(name, order, default = false)

```
case params[:order]
  when default && nil
    className = "ordered_desc"

  when order
    className = "ordered"
    order = "#{order} desc"

  when "#{order} desc"
    className = "ordered_desc"
end

options = params.merge(:order => order, :page => nil )

```

> > link\_to(name, options, :class =\> className)  
> > end

Seems that link\_to uses url\_for

Ok so i made a SMRT error the night before.

I created, as a test, an attribute called @controller in my  
base\_controller (from which all controllers inherit function).

This causes the errors.

Case closed, i have a bad memory.
