I have the following code that works very well

@manufacturer = Manufacturer.find\_manufacturer(params[:id])

which produces the following SQL:

SELECT \* FROM `manufacturers` WHERE (`manufacturers`.`id` = 4) #Here  
params[:id] =4

ON my view I can access the fields using

@manufacturer.field\_name

However when I do the following

@manufacturer = Manufacturer.find(:all, :conditions =\> {:id =\>  
params[:id]})

Which produces the same SQL as above:

SELECT \* FROM `manufacturers` WHERE (`manufacturers`.`id` = 4) #Here  
params[:id] =4

I get the following error on my view:

NoMethodError in Public\_manufacturers#show\_manufacturer\_details

Showing  
app/views/public\_manufacturers/show\_manufacturer\_details.html.erb where  
line #4 raised:

undefined method `logo’ for #Array:0x26e4838

Why is this happening and how can I solve it?

Thank you in advance.

find(:all, …) returns an array.

find(:first, …), or equivalently, find\_manufacturer(some\_id) returns  
a single item.

try:

@manufacturers = Manufacturer.find(:all, :conditions =\> {:id =\>  
params[:id]})

@manufacturers[0].show\_manufacturer\_details.
