php - Magento order status change events -

-

I want to change a remote list through the web service, I know that through the Event Observer method, my code Triger, but I do not know which event is useful for completing my work, such as ______ complete, there is an updated list of events or more documents?

If you want to transmit an event, when an order changes in any situation or situation , You have to include your own event listener. It is not as difficult as it sounds.

If you override the _setStatus function Mage_Sales_Model_Order is the same ... 

  / ** * Order Model * * @ Category WMG * @ Packet WMG_Sales * @Author Lee Bolding & lt; Lee.bolding@wmg.com> * Supported events: * Sales_order_status_before * Sales_order_status_after * Note: Unfortunately, we * functions can not override is done by * function registerCancellation (as _setState protected setState () ()) and _checkState () * / Square WMG_Sales_Model_Order extends Mage_Sales_Model_Order {/ ** * Order State Protected Setter * Allows to set any state by default. Also the default or position fixed value can be updated * Сomplete and closed states are deliberately updated, see _checkState () * * @param string $ state * @param string | bool $ conditions * @param string $ comment * @param bool $ isCustomerNotified * @param $ shouldProtectState * @return Mage_Sales_Model_Order * / protected function _setState ($ state, $ status = false, $ comment = '', $ isCustomerNotified = null, $ shouldProtectState = false) before we try {// an event dispatch anything mage :: dispatchEvent ( 'sales_order_status_before', array ( 'order' = & gt; $ this, 'state' = & gt; $ state; 'Status' = & gt; $ position, 'comment' = & gt; $ comment, 'isCustomerNotified' = $ is customer-appointed, 'project-state' = & gt; $ protected;); // attempts to establish state specified ($ ShouldProtectState) {if ($ this- & gt; isStateProtected ($ state)) {Dana :: ThrowException (Mage :: helper ( 'sale') - & gt ; __ ('order state "% s" should not be set manually.', $ State)); }} $ This-> Setdata ('state', $ state); // Add status status history ($ position) {if ($ position === true) {$ status = $ this- & gt; GetConfig () - & gt; GetStateDefaultStatus ($ state); } $ This- & gt; Setstats ($ position); $ History = $ this- & gt; AddStatusHistory comment ($ comment, incorrect); $$ does not make sense to restore status $ history-> Set Ice Customer Notification ($ isCustomerNotified); // for the rear compatibility) // has changed the situation after an Mage Post: Migration DispatchEvent ('sales_order_status_after', array ('order' = & gt; $ this, 'state' = & gt; $ state, 'Status' = & gt; $ position, 'comment' = $ gt; $ comment, 'customer-appointed' => $ is assigned to client, 'projectstate' => $ protected protected location) ; $ This return;

Now the newly created sales_order_status_before and sales_order_status_after event

windows - Heroku throws SQLITE3 Read only exception -

-
After I deploy the app to Heroku, I have to run migration scripts and get this error message ... ITES \ padrino \ prophetmargin & gt; Heroku Rack AR: Rack mutated! SQLite3 :: ReadOnlyException: only one try to write database to read: CREATE TABLE "schema_migrations" ( "version" varchar (255) NOT NULL) /disk1/home/slugs/215264_925fd2c_65a3/mnt/.bundle/gems/gems/ padrino-core- is 0.9.11 / lib / padrino-core / cli / rake.rb: 9: in `init ' how can this be? I also tried to run Heroku dbpush SQLite: //db/my-db.db and that did not work Horoku sqlite3 but using postgres does not do. I'm not sure why you are receiving this error, however, as I have used sqlite3 in development and when pushing it into its travel, they do some magic which migrates to postgrads. I'm absolutely sure how Heroku does 'backwash' this database but it seems that this is happening to you because it's the SQLite db file which is obviously due to Heroku's

lex - Building a lexical Analyzer in Java -

I am currently learning lexical analysis in compiler design. To know how a lexical analyzer actually works, I am trying to build myself. I am planning to make it in Java The input to the lexical analyzer is a .tex file that is of the following format. \ section {script} {intro} \ section {Scope} arbitrary text \ section {relevance} uncontrolled text \ subdivision (profit) arbitrary text \ subsubsection {in real life} \ subdivision {Ingredient} \ end {document} The output of the lecture may be a table of contents with a page number in another file. 1 Introduction 1 1.1 Scope 1 1.2 Relevance 2 1.2.1 Benefits 2 1.2.1.1 Real life 2 1.2.2 loss 3 I hope that This problem is within the scope of Language Analysis Read the .exe file and check '\' and continue to check whether it is actually on search In the sectioning command is set to indicate whether or not a flag variable is the type of sectioning. I hope the above approach will work for the construction of Lexa

python - rename keys in a dictionary -

-
I want to change the names of keys in a dictionary which are ints, and I need them so that the inputs with key zero They can sort correctly. For example, my keys are like this: '1', '101', '11' and I may need them: '001', '101', '011' What is doing, but I know that there is a better way tmpDict = {} in the ADC for the old: t MpDict ['% 04d'% int (olden)] = addict [oldkey] New controlled = tmpDict You are going wrong about this if you want to draw entries on a line in a specific way, then you have to sort on the extraction. for sorted (D, key = int): print '% s:% R'% (k, d [k]) < / Div>
