In the Carrier Model, pulling the products works via $request->getAllItems() and then getting the Product $item->getProduct().
I can't seem to figure out how to pull a custom product attribute.
$item->getProduct()->getAttribute('custom_attr'); // nothing
$item->getProduct()->getResource()->getAttribute('custom_attr'); // uses up 3GB memory and dies
$item->getProduct()->getCustomAttributes(); //empty array
$item->getProduct()->getExtensionAttributes(); //empty array
also tried creating the extension_attributes.xml
found it, finally :) Not sure if there is a better way as to load the whole product but works for now.
$_product = $objectManager->get('Magento\Catalog\Model\Product')->load($item->getProduct()->getId());
$attr = $_product->getData('attribute_name');

In case we had the model:
class Publication(models.Model):
title = models.CharField(max_length=30)
class Article(models.Model):
publications = models.ManyToManyField(Publication)
According to: https://docs.djangoproject.com/en/4.0/topics/db/examples/many_to_many/, to create an object we must have both objects saved before we can create the relation:
p1 = Publication(title='The Python Journal')
p1.save()
a1 = Article(headline='Django lets you build web apps easily')
a1.save()
a1.publications.add(p1)
Now, if we called delete in either of those objects the object would be removed from the DB along with the relation between both objects. Up until this point I understand.
But is there any way of doing that, if an Article is removed, then, all the Publications that are not related to any Article will be deleted from the DB too? Or the only way to achieve that is to query first all the Articles and then iterate through them like:
to_delete = []
qset = a1.publications.all()
for publication in qset:
if publication.article_set.count() == 1:
to_delete(publication.id)
a1.delete()
Publications.filter(id__in=to_delete).delete()
But this has lots of problems, specially a concurrency one, since it might be that a publication gets used by another article between the call to .count() and publication.delete().
Is there any way of doing this automatically, like doing a "conditional" on_delete=models.CASCADE when creating the model or something?
Thanks!
I tried with #Ersain answer:
a1.publications.annotate(article_count=Count('article_set')).filter(article_count=1).delete()
Couldn't make it work. First of all, I couldn't find the article_set variable in the relationship.
django.core.exceptions.FieldError: Cannot resolve keyword 'article_set' into field. Choices are: article, id, title
And then, running the count filter on the QuerySet after filtering by article returned ALL the tags from the article, instead of just the ones with article_count=1. So finally this is the code that I managed to make it work with:
Publication.objects.annotate(article_count=Count('article')).filter(article_count=1).filter(article=a1).delete()
Definetly I'm not an expert, not sure if this is the best approach nor if it is really time expensive, so I'm open to suggestions. But as of now it's the only solution I found to perform this operation atomically.
You can remove the related objects using this query:
a1.publications.annotate(article_count=Count('article_set')).filter(article_count=1).delete()
annotate creates a temporary field for the queryset (alias field) which aggregates a number of related Article objects for each instance in the queryset of Publication objects, using Count function. Count is a built-in aggregation function in any SQL, which returns the number of rows from a query (a number of related instances in this case). Then, we filter out those results where article_count equals 1 and remove them.
I have a project that requires syncing where in syncing is to gather all the data from all tables at start up. Kinda easy.
However with Node.js with the framework Sails.js, I cant seem to find a way to do so as one model is equal to one table, all laid out in projectName/api/models/ as a single file for each.
My initial idea was to loop everything in that directory to be able to do my query for each item, however it doesn't work as I have tried.
Here is my source code for the simple query for only one model:
modelName.getDatastore().sendNativeQuery('SELECT * FROM table WHERE id = 0' ,function(err, res) {
if (err) {
console.log(err);
return exits.success(err);
}
return exits.success(res);
});
With what I have tried (not in my sample above), I changed the modelName into string to test out if looping the directory works, which it doesn't. I also tried temporarily creating a simple variable that represents one of the model's name and used it for query, which also didn't work. I'm at my wit's end and can't find a solution even in google. Any help?
Im trying to create a customer deposit record in Netsuite using suitescript 1.0.
The original code I had in place which had been working perfectly up until the 2016.2 release broke it.
The update broke it, in that it would override the value submitted in the payment field and instantly make it the full amount of the sales order from the sales order ID. Which is not what we need it to do.
Original Code
function createDeposit(request,response)
{
var record = nlapiCreateRecord('customerdeposit');
record.setFieldValue('salesorder','1260');
record.setFieldValue('customer','1170');
record.setFieldValue('payment','100');
record.setFieldValue('account','2');
record.setFieldValue('memo','this is a test');
deposit = nlapiSubmitRecord(record,true,false);
response.write(deposit);
}
After a reply on the Netsuite user group prompted me to use the {recordmode:'dynamic'} attributes I am getting a strange error..
Test Replacement Function which doesnt work
function createDeposit(request,response)
{
var record = nlapiCreateRecord('customerdeposit',{recordmode:'dynamic'});
record.setFieldValue('salesorder','1260');
record.setFieldValue('customer','1170');
record.setFieldValue('payment','100');
record.setFieldValue('account','2');
record.setFieldValue('memo','this is a test');
deposit = nlapiSubmitRecord(record,true,false);
response.write(deposit);
}
The error message Im getting now is
Invalid salesorder reference key 1260 for customer .
The thing I dont get is how it is now considered NULL, when the value is hardcoded into this test script after I apply the {recordmode:'dynamic'} value.
Ive tried a wide variety of things, but as I dont have Netsuite support, its proving to be something I simply cant figure out.
Any hints, suggestions would be greatly appreciated as Ive been on this for several days
When you use dynamic the order you set fields makes a difference. So when you set the sales order prior to setting the customer you are actually getting the error message "Invalid salesorder reference key 1260 for customer blank"
What I do is create the customer deposit like:
var depRec = nlapiCreateRecord('customerdeposit', {entity:soRec.getFieldValue('entity'), salesorder:soId});
also setting the undeposited funds flag seems to be required (but not always for some reason) so since you are supplying an account id also do this:
depRec.setFieldValue('undepfunds', 'F');
Just as a test to see if it worked on one record I created the following mass update script and it doesn't seem to be updating the record I am telling it to but I get no errors. What am I doing wrong?
function shipCarrier(rec_type) {
var recid=11952;
var cust=nlapiLoadRecord(rec_type, recid);
cust.setFieldValue('shippingcarrier','UPS');
nlapiSubmitRecord(cust);
}
When I change your code to use cust.setFieldText() rather than cust.setFieldValue(), it works for me as a mass update script.
setFieldValue() is looking for the integer ID of the UPS item rather than the text.
I'm just getting started with Subsonic 3.0 ActiveRecord and am trying to implement a batch query like the one in the SubSonic docs. I'm using a batch so I can query a User and a list of the users Orders in one shot.
When I call the BatchQuery.Queue() method, adding my "select user" query, SubSonic throws the following exception:
System.InvalidOperationException : Can't decide which property to consider the Key - you can create one called 'ID' or mark one with SubSonicPrimaryKey attribute
The code is as follows:
var db = new MyDB();
var userQuery = from u in db.Users //gets user by uid
where u.uid == 1
select u;
var provider = ProviderFactory.GetProvider();
var batch = new BatchQuery(provider);
batch.Queue(userQuery); //exception here
//create and add "select users orders" query here...
First things first - Why this error? My SubSonic Users object knows it's PK. "uid" is the PK in the database and the generated code reflects this. And I thought SubSonicPrimaryKey attribute was for the SimpleRepository? Is this way of batching not for ActiveRecord?
I could ask a number of other questions, but I'll leave it at that. If anyone can help me figure out what is going on and how to issue 2 batched queries I'd be grateful!
Edit - after further investigation
I ran through the source code with the debugger. Adam is correct - the ToSchemaTable() method in Objects.cs is apparently building out my schema and failing to find a PK. At the very end, it tries to find a column property named "ID" and flags this as the PK, otherwise it throws the exception. I added a check for "UID" and this works!
Still... I'm confused. I'm admittedly a bit lost after peeling back layer after layer of the source, but it seems like this portion of code is trying to build up a schema for my table and completely ignoring my generated User class - which quite nicely identifies which column/property is the PK! It doesn't seem quite right that I'd be required to name all keys "ID" w/ ActiveRecord.
I think the answer you're looking for is that this is a really stupid bug on my part. I'm hoping to push another build next week and if you could put this on the issue list I'd really appreciate it. My apologies...
SubSonic expects your primary key to be called Id so it's getting confused. SubSonicPrimaryKey is for simple repository but I assume where that exception is being thrown is shared between the different templates. If you rename your PK to Id or id or ID your query will work.
