I'm trying to make query in RoR, but my conditions are coming from params and changing dynamically.
I've tried this:
@userlist = User.find(:all, conditions:{(name:params[:name] if params[:name] != nil), (lastname:params[:lastname] if params[:lastname] != nil)})
It's just my imagination, but shows what I mean.
thanx
If you're on Rails 3:
@userlist = User.scoped
@userlist = @userlist.where(name: params[:name]) if params[:name].present?
@userlist = @userlist.where(lastname: params[:lastname]) if params[:lastname].present?
etc..
you could do something like:
BlahController < ActiveController::Base
before_filter :find_params, :only => :index
def index
@user_list = User.where(@filtered_params).all
end
def find_params
@filtered_params = params[:name].present? ? "'name = ?', #{params[:name]}" : "'last_name = ?', #{params[:last_name]}"
end
end
So I assume you only have two conditions, a params[:name]
or a params[:last_name]
. If there are more, simply change the ternary to a if elsif
statement.
