We have a flash developer who is intergating with a rails application  
when  
he posts a particular variable (in this case ‘rating’) We get a ‘Rails  
Application  
Error’ Trawling the production log turns up this error;

NoMethodError (undefined method `stringify\_keys!’ for “10”:String):

The html wireframe has no such problem. A select box is used to submit  
the data  
in the style of.

rating[rating]

Here is the ‘def’ in the controller;

def rate  
dream = User.find(params[:id])  
rating = Rating.new(params[:rating])

```
# Create or Update rating cookie
if !cookies[:rating]
  cookies[:rating] = { :value => User.sha1(@request.remote_ip + 

```

Time.now.to\_s), :expires =\> Time.now + 31449600}  
else  
cookies[:rating] = { :value =\> cookies[:rating], :expires =\>  
Time.now + 31449600}  
end  
rating.cookie = cookies[:rating]  
dream.ratings \<\< rating  
if dream.update  
flash[:notice] = ‘Rating was added to this dream.’  
redirect\_to :action =\> ‘show’, :id =\> dream  
else  
render :action =\> ‘show’  
end  
end

Is there something wrong with submiting a post variable called ‘rating’  
in this way is there another method that im missing?

Thanks in advance.

Which line is the error on, and what does your param hash look like?
