I have an array I’m trying to output with partials. The query find  
entries in the database correctly but the results are getting  
outputted repeatedly.

## For example, if there are 3 results from the query it would display the 3 partials 3 times, if it was 4 it would repeat 4 times etc. Heres what it would look like if "@albums = Album.find(@albumids) " found 3 ID’s

## First Partial (id=1) Second Partial (id=2) Third Partial (id=3) First Partial (id=1) Second Partial (id=2) Third Partial (id=3) First Partial (id=1) Second Partial (id=2) Third Partial (id=3)

Heres the array and query

```
 @activity = Activity.count( :group => 'album_id',
                             :conditions => ['created_at >= ?',

```

@time],  
:order =\> “count\_all DESC”,  
:limit =\> 5 )  
@albumids = @activity.map { |a| a[0] }  
@albums = Album.find(@albumids)

And partial line

\<%= render :partial =\> “album”, :collection =\> @albums %\>

Any thoughts?

I suspect you have a problem with the query that sets up @albumids; your  
render line will generate a line for each object in the @albums  
collection, so if you are seeing the same album repeated, it is likely  
because it is repeated in the @albums collection.

You could check this by running ruby script/console, and testing your  
find logic by entering the three lines:  
@activity = Activity.count( :group =\> ‘album\_id’,  
:conditions =\> [‘created\_at \>= ?’,  
@time],  
:order =\> “count\_all DESC”,  
:limit =\> 5 )  
@albumids = @activity.map { |a| a[0] }  
@albums = Album.find(@albumids)

Hope this helps…
