问题 I fear I've stumbled into unknown Magento territory. I have exhausted what's left of my Googling abilities and have come up short, so I thought I'd try my luck here. Our platform is Magento Enterprise 1.9.1.1. We use an archaic print solution that reads orders via ODBC. As such, we can't have it read from Magento's MySQL database directly (thanks to the high likelihood of change). What I've done is extend Mage_Sales_Model_Order to intercept the _beforeSave() function with direct SQL queries

问题 I am using Redis' INCR to generate an ID for objects. And then use ZADD to add the object using the ID as key. Do I need to worry about if there are multiple connections executing this same block of code? Say after id:12 if two connections connect at the same time and both add object using id:13 , then one of them would be lost. 回答1: Since redis is single threaded, this can never happen - only one client can make a change to the database at a time. 回答2: As Jonatan Hedborg stated, Redis is

问题 so I am rewriting some Obj-C code in Swift and stumbled across a block which drives me crazy. I've already had a look at the documentation provided by apple and some other resources here on stackoverflow. Unfortunately, I couldn't find the solution, yet. IÄve got that piece of obj-c code which I want to re-write in Swift. Maybe you can help me figuring out how to do that. I'd really appreciate it! - (void)startSearchWithCompletionHandler:(PHBridgeSearchCompletionHandler)completionHandler; And

问题 I've been fiddling in Xcode 4.2 with iOS 5.0's new NSLinguisticTagger. My objective with this function is to take in an address book record and then spit out a composite name as an NSString, sort of like what ABRecordCopyCompositeName does, but taking into account naming order for East Asian languages and Hungarian (last first instead of first last). Here's the function: NSString *text = [self getLocalizedFullNameOfRecord:[contacts objectAtIndex:indexPath.section]; - (NSString *)

问题 To make long story short: each of my tabs has its own form, so I decided to make a single layout and just to have a forms themselves as a variable content for a layout. But I need to have form_for to be in a layout, rather then having it in each of the forms, because I have some other common form elements in the layout. So how can I pass the form builder's reference f to the template ? Layout code: <% content_for(:content) do %> <%= form_for current_form do |f| %> <%= yield %> <%= f.submit

问题 [[RKObjectManager sharedManager] loadObjectsAtResourcePath:@"app/site_pattern" usingBlock:^(RKObjectLoader* loader) { [loader setObjectMapping:clientMappring]; loader.delegate = self; shopLoader = loader; }]; Above, I use the block function to load some data in my app, but when I pop this viewcontroller, I don't know when and how to cancel this request . Any idea? - (void)showSelectShop { SelectShopViewController * selectShopViewController = [[SelectShopViewController alloc] initWithNibName:@

问题 I am developing a web application which communicates with other web applications. From time to time, my system sends HTTP request as notification to other systems. Since their responses are not essential to me, I send the requests with Java 8 CompletableFuture supplyAsync and prints their responses with thenAccept so that my main thread will not get blocked. However, I found the CompletableFuture function chains took around 100 to 200 ms each time, which confused me because from my

问题 I have created a block and I have placed it in to the layout xml and it is showing correctly in my theme. My problem is that I actually don't want it to display until I explicitly call it with getChildHtml('myblock'). My block xml looks like this: <block type="page/html" name="myblock" as="myblock" template="page/html/myblock.phtml"/ > Anyone have a clue how to achieve this? Thanks 回答1: Place your block inside another that is neither a core/list type nor calls $this->getChildHtml('') (note

问题 This seems like it should be pretty straightforward, but for some reason I am unable to solve this problem. I'm using Django 1.4. I am trying to do a basic check to see if a list QuerySet is empty or not during template rendering, but the if statement I'm using seems always to evaluate to true. I have a Django template that reads: {% extends 'includes/base.html' %} {% if object_list %} ... {% block data %} {% for object in object_list %} ... {{ object.create_date }} ... {% endfor %} {%

问题 Long time lurker, first time poster. I'm relatively new to objective-C so my apologies if I'm asking something fairly simple. My google & stack overflow-fu has let me down here, so I figured somebody could maybe help. I have a synchronous process executing, say, three functions in a row - call it A -> B-> C , where task A executes, followed by B, followed by C. Now, B involves an asynchronous process with a delegate callback for completion. But B must complete before C is executed, so I need
