    copied!<p>For my life I trying to find out why are my callbacks are not getting executed <code>sometimes</code>(you heard it right <strong>sometimes</strong> as most of time it works out of the box)</p> <p>All I have is parent/child relations between 2 models </p> <p>upon creation of child record all I'm doing in <code>after_create</code> callback is update(accumulate all child amount in parent field to avoid heavy query at run time) the amount field in parent table/ model record</p> <p>Parent model(<code>Payout</code>) </p> <p>Child model is (<code>Sales Transaction</code>) </p> <p><code>Payout</code> <strong>has_many</strong> <code>SalesTransactions</code> as said above upon creation of sales transaction I'm updating(incrementing to be precise) the <code>amount</code> field of parent record (payout record) so as to avoid heavy query at run time.</p> <p>so Payout <code>amount field</code> is nothing but summation of all amount of the <code>sales_transactions</code> of that payouts</p> <p>it as good as saying as payout.amount would be(after callback is executed)</p> <p><code>payout.amount == payout.sales_transactions.pluck('amount').sum</code> </p> <p>and that what I trying to achieve using callbacks</p> <pre><code>class SalesTransaction &lt; ActiveRecord::Base belongs_to :payout after_create :update_payout_for_sale def update_payout_for_sale sales_amount = payout.amount || 0 sales_amount = sales_amount + amount.to_f ## Also make note of the minus from original amount i.e refund and custom_deduction_amount payout.update_attributes(:amount =&gt; sales_amount) end end class Payout &lt; ActiveRecord::Base has_many :sales_transactions has_one :referrer after_save :update_referrer_earning def update_referrer_earning referrer.update_attributes(:amount =&gt; (amount*10)/100.to_d)) rescue nil end end </code></pre> <p>The interesting part over here is that <code>sometime</code> when SalesTransaction is <code>created</code> the callback is just not called as I dont see the update value of the in payouts record </p> <p>I'm trying to avoid the callback for now but for the sake knowing <code>why</code> the callback is not getting executed has <code>led me</code> to ask this question</p> <h2>NOTE</h2> <ol> <li><p>There is not Validation neither on SalesTransaction and Payout table ( I have check this 1000 times) <code>Payout.validators</code> => []</p> <p><code>SalesTransaction.validators</code> => []</p></li> <li><p>There is no mass asssignment issue as I havent define <code>attr_accessible</code> or <code>attr_protected</code> (I Check this as well and also as said it work most time which wouldn't have been the case with mass-assignment warning)</p></li> <li><p>SalesTransaction record is getting created all the time only the payouts record is not getting update(<code>sometime</code>)</p></li> <li><p>I have removed most of the unwanted(over here) associations from <code>sales_transactions</code> and <code>payouts</code> for code brevity </p></li> <li><p>No there isnt any thing like <code>accepts_nested_attributes_for</code> on either of the models </p></li> <li><p>No dynamic validations attached ,extra, extra </p></li> </ol> <p>Lastly Here how I'm trying to create the <code>SalesTransaction</code></p> <pre><code> options = {"performer_id"=&gt;177, "customer_id"=&gt;35526, "sale_type"=&gt;"sale", "show_id"=&gt;502, "performer_percentage"=&gt;BigDecimal.new("40.0"), "show_duration"=&gt;4104, "gross_credits"=&gt;3754, "gross_sales"=&gt;BigDecimal.new("375.4"), "amount"=&gt;BigDecimal.new("150.16"), "affiliate_id"=&gt;nil, "affiliate_earning"=&gt;BigDecimal.new("0.0"), "total_profit"=&gt;BigDecimal.new("225.24"), "payout_period_id"=&gt;89,"payout_id"=&gt;4156, "stream_connection_id"=&gt;540572, "history_id"=&gt;44575, "credits"=&gt;{:when_show_started=&gt;350, :purchased_during_show=&gt;{:free=&gt;[], :paid=&gt;[]}, :total_consumed=&gt;{:free=&gt;350, :paid=&gt;3754}}, "sliding_scale_recalculations_done"=&gt;false, "paid_minutes"=&gt;62.57} </code></pre> <p><code>SalesTransaction.create(options)</code></p>
