Will the find from acts_as_paranoid filter down to an :include? For instance class parent acts_as_paranoid has_many: children end and class child acts_as_paranoid belongs_to :parent end Then if you Parent.find(:all, :include => children) you will get all the children if they are deleted or not. I guess the find that filters out the deleted_at is null does not filter down to the includes

Hi, guys I have a puzzle about default_scope. Suppose I have two model: class User < ActiveRecord::Base has_many :blogs default_scope where(deleted_at: nil) end class Blog < ActiveRecord::Base belongs_to :user end I want to produce sqlselect blogs.* from blogs inner join users on users.id = blogs.user_id and users.deleted_at is null And the code Blog.joins(:user), which I think

As far as I can tell, the counter_cache option on a belongs_to model doesn''t actually save anything in the database.

Hello all, I apologize if the answer to this question is going to be rudimentary, but I am thus far stymied by the information I have found on the web. This seems like it should be simple, but I haven''t really found an example of how to do this yet.

Hi, I''ve run into two small problems with acts_as_paranoid and wondered if anyone else has experienced them as well (and if yes, if they have any solutions). 1. When using has_many :through, AAP doesn''t seem to take into account the fact that your join model might also be paranoid. My solution to this at the moment is to add an explicit conditions clause to the has_many

This is my first question to the Forum.

I''m having trouble with a validation that depends on an attribute of a belongs_to parent. If the child is added to an unsaved parent (parent.children << new child), the has_many collection parent.children includes the unsaved child. However the belongs_to attribute child.parent appears to be nil until the parent has been saved. Without access to the parent attributes, the validation

Hi! This is my first post in this forum. I''m learning RoR for two weeks and I''m very interested about how to improve this framework. I was testing one app I''m working in and I had some problems with destroying. The code is simple (and maybe wrong, as I said i''m just learning!).

Hi.. Guys new plugin again Foreign Key Associations is a plugin that automatically creates associations based on foreign-keys. The associations are created at runtime-ie. as your ActiveRecord models are loaded-so they will always be up-to-date. For example, given a foreign-key from a customer_id column in an orders table to an id column in a customers table, the plugin creates:

I am implemented a simple project management application. Each project has various events, and each event can be a different type. Some event information is common, such as name, start date, close date, and comments. I have a projects table which has_many events.
