Add a custom order note programmatically in Woocommerce admin order edit pages

阅读更多关于 Add a custom order note programmatically in Woocommerce admin order edit pages

问题 In woocommerce I am trying to add a custom order note in the admin order edit pages through php (so programmatically). I haven't find the way yet. Any help will be appreciated. 回答1: From a dynamic Order Id you can use WC_Order add_order_note() method this way: // If you don't have the WC_Order object (from a dynamic $order_id) $order = wc_get_order( $order_id ); // The text for the note $note = __("This is my note's text…"); // Add the note $order->add_order_note( $note ); Tested and works.

Django: Detect database backend

阅读更多关于 Django: Detect database backend

问题 I'm doing some "extra" queries in Django that need to work on both sqlite and postgres. The syntax of these queries varies between backend but I have no way of figuring out if I'm sending my queries to either postgres or sqlite. Is there a way to get the current database adapter so I can branch my code and send the right query for the active database server? 回答1: OK, so there's two ways of doing it, as @Ricola3D said there's the option of checking settings.DATABASES['default']['ENGINE'] : >>>

Matplotlib and Pyplot.close() not releasing memory? - backend related Qt4Agg

阅读更多关于 Matplotlib and Pyplot.close() not releasing memory? - backend related Qt4Agg

问题 EDIT: If I explicity change the backend for matplotlib from 'Qt4Agg' to just 'Agg' then I am able to run my code with no errors. I assume this is a bug in the backend? I am writing some code for processing a fairly large amount of data automatically. The code first of all parses my data files and stores all of the relevant bits. I then have different functions for producing each of the graphs I need (there are about 25 in all). However, I keep running into some kind of memory error and I

I am using Flowjs, and its ng-flow directive to upload file with NodeJS as backend. When i try to upload file, only file in tem folder is uploaded, but it's note any type of file like JPG or PNG. (flow-135601-juicy_gustinektar02l_10185jpg.1).

Can WordPress handle these functionalities?

阅读更多关于 Can WordPress handle these functionalities?

I'm a front-end designer/developer whose weapon of choice for the back-end is WordPress. Up to this point all of my projects involving WordPress were fairly basic and it has handled everything beautifully. I just landed a new client that wants some extra functionality built into his next project and I'm hoping some of you WordPress wizards can give me some good advice while I'm putting together the quote. I'm trying to limit the need for any subcontracting for the back-end functionality, so my question is whether or not WordPress can handle the following (via plugins or light custom

TYPO3: Filter frontend users by usergroup in backend?

阅读更多关于 TYPO3: Filter frontend users by usergroup in backend?

Is there a feature or backend extension or that can filter list records? Right now, you can only check a single user record or sort by usergroup. I am looking for a module where I can choose the usergroup and get a list of all assigned users (FE users) in the backend. Or a standard feature I haven't discovered yet. Maybe similar to filtering news articles in tt_news by category. If it doesn't exist, I will have to code it myself. Not in the List module but you can do this by setting an action . It can be set only by an admin but can be used by any backend user that you allow. In the Extension

How to run Google app engine endpoint methods from the backend

阅读更多关于 How to run Google app engine endpoint methods from the backend

问题 I have followed all the configuration steps for my WarmupServlet in my app engine project and I see it run at startup, but still I see my first endpoint call as a loading request which takes up to 25 seconds which is absolutely unacceptable. I need to be able to warm up each endpoint individually so that there will be no loading requests. (Apparently just setting up a warmp-up servlet is not enough.) So, my question is, how can I call a method in endpoints so that the endpoint is properly

Android Backend Starter setFilter

问题 I'm trying the new Android Mobile Backend. I did all the basic samples and now I want to set one or multiple filters. I tried only with one but the getCloudBackend().list returns a null list. I have in the entity that I filter the parameter with the value. And if I remove the line where I filter, the service returns a list with data. What I have to do if I want to filter by one parameter? and if I want to filter by the owner? and if I want to put more than one filter? This is my code:

Matplotlib says fig.canvas is None, so I can't use fig.canvas.draw

阅读更多关于 Matplotlib says fig.canvas is None, so I can't use fig.canvas.draw

I haven't used Matplotlib much. Based on someone's advice, I'm trying to write some plotting codes using object-oriented paradigms as much as possible---and therefore trying to use pure Matplotlib (i.e. not relying on pyplot) to generate some simple figures. A stripped-down version of my code looks like this: import matplotlib as mpl time = [0,1,2,3,4] cell = [1,2,1,2,1] sample = [3,2,3,4,4] (figHt, figWd) = (5, 8) # in lBorderWidth = bBorderWidth = rBorderWidth = tBorderWidth = 0.1 lbwh = (lBorderWidth, bBorderWidth, (1-lBorderWidth-rBorderWidth), (1-tBorderWidth-bBorderWidth)) # left, bottom
