Array and Set parameters in .find search

Hi everybody...

I'm getting crazy to understand how to make things working..
I have to use both Solr and rails Find to filter search result, and I
realized that the only option is to get the ids from the different
search results..and then intersect the array of the ids.

Once did this..I can't make find_all_by_id work passing the resulting
array as parameter, I have this:

----
using @articles = Article.find_all_by_id(@ids)
It seems to work, I get results, but they're wrong! :S

That should work. Does the generated sql look right ?

nope, it doesn't I get other authors and Dates out of the range
the funny thing is that if I pass the array number manually it works!
how can I print the @ids variable in the view? just to have a log..

(btw I've just realized that I can avoid the two Article.find arrays
by extending conditions in only one of them :P)

You could use debug. What's wrong with the generated sql? Also, you
say you are intersecting the relevant finds but you seem to be just
concatenating them.
Lastly, given that you already have all the Article objects, why go
back to the database (ie why not @aut & @range & @search) ?

because I have to do the @search part using acts_as_solr (for studying
purpose)

(I've bound @aut and @range in the se same query now)

I realise this, but given that (as far as I can tell) you've loaded
all of your article objects you might as well to the intersection of
the various results there and then rather than intersecting their ids
and loading them again from the database.

Fred

Um, maybe they are wrong because you haven't computed the intersection
of the arrays above - you've found the union.

Note that it should work to do this:

proxy = Article.scoped(:conditions => { :author => params[:author] })

from = params[:from][:date] # may need .to_date here
to = params[:to][:date] # I'm assuming there was a typo in the
original
proxy = proxy.scoped(:conditions => { :date => from..to })
@articles = proxy.find_by_solr(params[:query])

The .results on the original find_by_solr is confusing; are you using
an old version?

Acts_as_solr doesn't 100% support scoping like this, but digging
around in the underlying code shows that the actual results are loaded
with a find(:all, :conditions => { :id => results }), which will apply
the other constraints.

Hey Matt, I hope I understood what you wrote..if so that might be
amazing! I'll try it tomorrow, i didn't know about old version
of .results, so what should I use instead? nothing? just find_by_solr
(params[:query])
I'll let u know! Thanks!

@Fred, yes, you're right :slight_smile:

here I am again :slight_smile:

So Matt, your trick didn't really worked.
I'm using this version of acts_as_solr. http://github.com/mattmatt/acts_as_solr

I did not understand the part u say about .results, if I don't use it
it returns an error (like I'm passing to @articles something that is
not an articles array), if I use .results it returns 0
articles..that's not right too...

What about find(:all, :conditions => {:id => results}) you wrote? I
did not understand how and where use it.
thanks again

:wink:

Making some tests I've realized that's it a range date matter...
I'll figured out and let u know

I've made a bunch of tests...

using:
proxy = Article.scoped(:all, :order => :date, :conditions => {:author
=> aut, :date => 2001..2006})
   @articles = proxy.find_by_solr(params[:query])

I get a Type error: Symbol as array index

actually using proxy = Article.scoped_by_author
and then proxy.find_by_solr

it seems to work..I just have an out of sync error..but that's another
story..I'll have a look

thanks!
