Question

i really need some help on this. I searched the internet but couldn’t find a single solution to my problem.

I have got an index.html.erb file which displays some records which have been retrieved using a rather complex find_by_sql. Please see code below:

def index
@refprobes = Refprobe.paginate_by_sql ["select * from ref_probe
                                      where RPR_OID in
                                (SELECT DISTINCT RPR_OID
                                FROM REF_PROBE
                                JOIN ISH_PROBE ON RPR_OID = PRB_MAPROBE
                                JOIN ISH_SUBMISSION ON PRB_SUBMISSION_FK = SUB_OID
                                JOIN SEC_USER_PI ON USP_PI_ID = SUB_PI_FK
                                WHERE USP_USER_FK = " + session[:user_id]+ ")"], :page => params[:page], :per_page => 10
end

Now i want to include a search field on top of my index.html.erb, which will allow user to filter those displayed entries based on the value inputted in the search field.

def self.search(search)
  if search
    find(:all, :conditions => ['name LIKE ?', "%#{search}%"])
  else
    find(:all)
  end
end

The above code does not fit my requirements as i don’t want to search through all the records in the table. I want to restrict my search to only those entries displayed my index.html.erb.

How can i do this?

Many many thanks in advance for your help..
