similar to: Feedback Needed: Optimistic Locking Destroy Bug

I''m working on an app that makes use of rails'' optimistic locking feature and seeing some possibilities for improvements. It seems a bit tedious to have to add :lock_version to forms wherever the model is used. You also have to "hack" around rails'' UJS feature to add it as a URL parameter when using remote: true, method: [:put, :patch, :post, :delete].

Hi all, I''ve searched the forumns, but I can''t seem to find an answer to this one. I''m having trouble getting optimistic locking (OL) to work in my app, even though all of the pieces are there: * table has lock_version column, with default of 0 (zero) * lock_version column is being incremented by the first update (but the second doesn''t catch it) *

Hi All, I''m having some trouble deciding when and how to implement optimistic locking. Let''s say I have a multiuser Rails app, and let''s say it stores, among other things "vital" customer information. The standard methods created by the Rails generate scaffold script look like this: def edit @customer = Customer.find(params[:id]) end

I understand that ActiveRecord supports the "optimistic offline lock"-pattern through magic fields (created_at, updated_at). However, a scaffolded CRUD-Controller doesn''t generate the necessary code to support this feature (the model state gets lost between two action calls). What is the best practice to prevent users from overwriting objects with outdated data ? --

Hi all! Recently I discovered that AR tries to treat question marks inside SQL string literals as parameters, however this behaviour shows in very rare cases, for example (very odd, but...): User.where("NOT EXISTS (#{ Comment.where(''user_id = users.id AND body ILIKE ?'', ''%?'').to_sql }) AND created_at > ?", Date.yesterday).to_sql It will fail,

I''m doing some work where I want to rescue ActiveRecord::RecordNotSaved from a save! call nested deep in the code. The thing is there could theoretically be failures here I want to pass through, and I want to inspect the record in order to decide. I figure a custom initializer on the exception class and a couple quick patches here and there in the code would make it minimally

hi folks. on rails 4, can somebody confirm that pushing model instances onto a has_many :through relation does not create the necessary join model anymore? class Reader < AR::Base belongs_to :post belongs_to :person end class Post < AR::Base has_many :readers has_many :people, through: :readers end @post.people << Person.new so,

I was taking a look at the implementation for reporting the time spent on each part of an action processing. Rails, by default will report timing for the view and db (ActiveRecord). Both use class attributes for storing the timing (or accumulating them in the case of AR), which are shared among all threads. This is fine if you''re deploying using the fork approach, like done by
