named-scope

I'm using the very helpful has_scope gem. I have an index page created by passing scopes in a link. <%= user_collections_path(@user, got: true) %> On that index page I can query the current_scopes. I have a pretty standard ransack search form on that page but using it returns results without any scopes. How can I pass the current_scopes on to the search? I tried using a hidden field but couldn't get it to work. I thought if I could pass the scopes in a link I ought to be able to pass them in a form but after googling I'm not sure that is true. Search form <%= search_form_for @search, :html =>

I love making named scopes for rails. however, I ran into somewhat of a pickle. Ive gotten pretty comfortable using named scopes for joins like so: named_scope :foo, :joins => :bar, :conditions => "bar_attribute = 'something'" Now pretend I have a table called baz which is contains a foreign key from the bar table. I need something like this: named_scope :foo, :joins => (:bar => :baz), :conditions => "bar.id = baz.bar_id AND baz_attribute = 'something_else'" How possible is this? thanks You are not that far off. This should work for you: named_scope: foo, :joins => {:bar => :baz}, :conditions

I recently broke up my query into 4 named scopes to make it easier to re-sort and will paginate which otherwise always worked fine now has problems calculating the number of pages. named_scope :loc, lambda { |id| { :conditions => ['location_id = ?', id ] } } named_scope :datem, lambda { |*args| { :joins => :scannables, :conditions => [ "scannables.bookdate BETWEEN ? and ?", (args[0].to_date || 3.days.from_now), (args[0].to_date+(args[1] || 3)) ], :group => 'scannables.hostel_id', :having => 'SUM(scannables.available) > ' + ((args[1] || 3).to_i-1).to_s } } named_scope :order_by_external_desc,

Is it possible to have named_scope return records unique for a certain column? e.g named_scope :unique_styles, :order =>"title desc", :limit => 3 That will give me three styles but what if I want to make sure the title is different? In this case there may be three records with the same style, I want this named_scope to only give unique values of title. So ["style 1", "style 1", "style 1"] isn't possible, it'll force itself to give ["style 1", "some style 2", "maybe another 3"] i think group may do it and I'm using that for now. If anyone has any comments regardless that'd be great. You

In my ApplicationController I have the demo_mode? method (which returns true when the currently logged in user type is "demo"). Post model has the publisher_id field, which refers to Users table. User has the user_type field, one of the possible values of which is "demo". Bottom line: post p was published by a "demo" user if and only if: User.find(p.publisher_id).user_type == "demo" I would like to create a named scope Post.relevant that will return: all posts that were published by "demo" users, if demo_mode? == true all posts that were published by non "demo" users, if demo_mode? == false

In my Rails3 model I have these two named scopes: scope :within_limit, where("wait_days_preliminary <= ? ", ::WAIT_TIME_LIMIT.to_i ) scope :above_limit, where("wait_days_preliminary > ? ", ::WAIT_TIME_LIMIT.to_i ) Based on their similarity, it would be natural for me to define the second by inverting the first. How can i do that in Rails? Arel has a not method you could use: condition = arel_table[:wait_days_preliminary].lteq(::WAIT_TIME_LIMIT.to_i) scope :within_limit, where(condition) # => "wait_days_preliminary <= x" scope :above_limit, where(condition.not) # => "NOT(wait_days_preliminary <
