I currently working on a ecommerce site using xcart 4.7.5. As per the client requirement i wrote some custom modules for csv uploads of products.Everything working fine. But sometimes all products renamed as restored_products and corrupt the product database values. i dont know what happened.I am so confused here.
Found it. its just beacause of function func_delete_product($productid).here if the productis null or empty they just erase all details from product_lng table. So i added some validations to it and now its works fine.

I have written a small django app and in it I can upload some documents and at another point I can make a reference from a payment to the corresponding document. But my problem is that the list of documents is always outdated. But when I kill my gunicorn and start the webserver again, then the dropdown list with documents loads correctly and also shows the newest file uploads.
Do you have an idea why Django behaves like that?
Best regards
Edit: I just saw that I have to edit this question.
So I have this in my forms.py:
dms_objects = dmsdok.objects.all().order_by('-id')
choices_dms = []
for dms_obj in dms_objects:
choices_dms.append((dms_obj.id, dms_obj.dms_dok_titel))
And also I have this in the form:
zahlung_dok_pseudo_fk = forms.IntegerField(required=False, widget=forms.Select(attrs={'class':'form-control',}, choices= choices_dms), label='Zugehörigkeit Dokument')
I guess that this is what Willem means, but I do not know how I must change that.
I am trying to save an array of text containing category types for a hotel system which looks something like this ['category-1', category-2', category-3, category-4] . I am using category_type = ArrayField(models.CharField(max_length=200),null=True) in my models.py
The error i get is
malformed array literal: "" LINE 1: ..., '{category-1,
category-2}'::varchar(200)[], ''::varcha...
^ DETAIL: Array value must start with "{" or dimension information.
The error persist even after processing python list from ['category-1', category-2', category-3, category-4] to {category-1, category-2, category-3, category-4}.
I have gone through postgresql documentation and have found very limited help,
https://pganalyze.com/docs/log-insights/app-errors/U114 this is something similar posted to what i am facing problem with.
Could someone please tell me what am i doing wrong? Any help would be appreciated.
EDIT:
Following is in my View.py
hotel_category=categoryTable(category_type=categorytype)
hotel_category.save()
and i am using categorytype=request.POST.getlist('category-type') in my Views.py to get it from the POST request after user submits the form. This returns a Python list that i have mentioned above, i have manipulated this list to match PostgreSQL ArrayField with '{','}' but i still have this error. If there is anything else you would like me to add, please let me know. :)
This is an update/answer to my question for anyone who faces this issue in the future. After struggling to find help from different resources, i decided to use JSON string to store my python list.
I am using :
categorytype = json.dumps(request.POST.getlist('category-type'))
to encode and using JSONDecoder() to fetch from database and decode. I have no idea how would this impact my further development but for now it seems a decent approach since personally i think ArrayFields are not well supported and documented in Django.
I will keep this post updated as i progress further on how this approach has impacted my development.
Have a nice day.
My django app uses update_or_create() to update a bunch of records. In some cases, updates are really few within a ton of records, and it would be nice to know what got updated within those records. Is it possible to know what got updated (i.e fields whose values got changed)? If not, does any one has ideas of workarounds to achieve that?
This will be invoked from the shell, so ideally it would be nice to be prompted for confirmation just before a value is being changed within update_or_create(), but if not that, knowing what got changed will also help.
Update (more context): Thought I'd give more context here. The data in this Django app gets updated through various means (through users coming on the web site, through the admin page, through scripts (run from the shell) that populate data from a csv etc.). The above question is important mostly for the shell scripts that update data from csvs, hence a solution at the database/trigger/signal level may not be helpful here (I guess).
This is what I ended up doing:
for row in reader:
school_obj0, created = Org.objects.get_or_create(school_id = row[0])
if (school_obj0.name != row[1]):
print (school_obj0.name, '==>', row[1])
confirmation = input('proceed? [y/n]: ')
if (confirmation == 'y'):
school_obj1, created = Org.objects.update_or_create(
school_id = row[0], defaults={"name": row[1],})
Happy to know about improvements to this approach (please see the update in the question with more context)

Unfortunately, databases don't work like that. It's the responsibility of applications to provide this functionality. And django isn't an application. You can however use django to write an application that provides this functionality.
As for finding out whether an object was updated or created, that's what the return value gives you. A tuple where the second value is a flag for update or create
I am using salesforce.cfc (downloded from Riaforge) to integrate coldfusion with salesforce.
<cfset latestProductList = salesforce.queryObject("SELECT Id, Name, Description__c, Price__c, ProductImage__c FROM Product__c") />
I have created one custom object named "Product__c". This object have one custom field "ProductImage__c" type "Rich TextArea". When i an trying to get product without this custom field it is run, but when i am trying to get product with this field i am getting below error:
"INVALID_FIELD: Name, Description__c, Price__c, ProductImage__c FROM Product__c ^ ERROR at Row:1:Column:44 No such column 'ProductImage__c' on entity 'Product__c'. If you are attempting to use a custom field, be sure to append the '__c' after the custom field name. Please reference your WSDL or the describe call for the appropriate names. "
But i have this field. attached screen image of salesforce below.
Thanks,

A quick look at Salesforce CFC shows that it hasn't been updated in a while. The file SalesForce.cfc is pointing at:
https://www.salesforce.com/services/Soap/u/11.1
That's version 11.1 of the API, which is quite old and is long before rich text fields came into existence.
You might be able to fix this issue by simply updating the reference in SalesForce.cfc to the latest version of the API by changing
https://www.salesforce.com/services/Soap/u/11.1
to
https://www.salesforce.com/services/Soap/u/28.0
in that file, although there's a pretty good likelihood that that will break something else, since version 28.0 will have lots of new stuff that SalesForce.cfc is not coded to handle.
In any case, your problem is in fact the API version that you're using. In cases like this, when a field type did not exist as of a certain API version, then that field is invisible for that version. In your case, your rich text field is invisible for your API version, 11.1.
I am using the API V2 "salesOrderList" for receiving a list of all the Orders which have been placed in Magento. But the SOAP Response is showing me an error as:-
Item (Mage_Sales_Model_Order) with the same id "1" already exist
I am using the Magento Enterprise version 1.9.0.0.
After looking into the SQL & searching the database, I found that for each Order, the SQL is providing 4 records for the same Order Entity ID; with the difference being only in the name fields of the billing & shipping area. Also the query is doing two Left Joins with the same database table "sales_flat_order_address" by using two different aliases (one for billing & another for shipping). From my understanding, this should have worked, which is not happening.
Can anyone please suggest as to what is happening & what can be done to recover from this error?
Any help is appreciated and thanks in advance.
Roughly, Magento is creating an order collection for you and attempting to load all the records. This collection has a rule that only allows it to create one order object for each ID, so when your additional object is loaded an exception is thrown.
The left joins could be the issue, but it's hard to say off the bat. Could you post a little detail on how you are making the API call? An incorrect join can often have this problem.
EDIT:
If you're using the default code, my first guess would be that there are erroneous records in the database, or that this is an upgraded Magento system which had a bad upgrade in the past. Try this on a clean copy of your EE version pointing to the same database. If the same problem occurs, you may need to spelunk in the database looking for the reason for the problematic data load. Since you already have the query, you may want to separate out parts of the query to see if some subquery is returning too much data.
