I’m trying to do one of those “build the sql where clause dynamically” searches based on what the user wishes to input.
I haven’t found much material on this , except for this:
I put together the code from this little tutorial - but from what I can see it seems to still depend that all form elements are used. Not in my scenario.
This is the code so far and I’m not sure the direction I’m going in here is even good
conditions = ['1=1'] # I thought I read that this could be used for a sql injection ? conditions << 'category_id = :category_id' if params[:category_id] # this seems fine (I think) however conditions << 'state_id = :state_id' if params[:state_id] # two of the 5 elements are text fields so LIKE would probably make more sense, in the event conditions << 'term_id = :term_id' if params[:term_id] # they typed goston or new yawk conditions << 'city = :city' if params[:city] conditions << 'title = :title' if params[:title] @positions = Position.find(:all, :conditions => [conditions.join(' AND '), params]) # I guess this is the part that is constraining the user to input all the conditions listed above ?
