Issues upgrading from wagtail 2.15.6 to 2.16 breaks all pages except home page - upgrade
I am experiencing an issue upgrading a site's wagtail installed version. I have successfully upgraded from 2.12 to 2.15.6 but am running into what seems to be an impassible issue with upgrading to 2.16 Specifically to do with this recent commit in 2.16 stable
https://github.com/wagtail/wagtail/commit/29a7f701611d22ab9c7f12f1134aeac1d31b9438
Every page except the root page of the site brings up the following error (including django and wagtail admins)

Following the upgrade docs https://docs.wagtail.org/en/stable/releases/2.16.html ran into this unexpected / undocumented issue.
Here is the context_processor that is causing the issue. which is getting a model of National Office which has on it multiple Pages that are foreign keys of wagtailcore.Page and the serialized_data method has some if statements checking for if the page foreign key exists and it is these checks that are triggering the wagtailcore code that is failing.
def site_settings(request):
domain = request.META['HTTP_HOST'].replace("www.", "")
try:
national_office = NationalOffice.objects.get(domain=domain)
return {"settings" : national_office.serialized_data }
except ObjectDoesNotExist:
print(" NO Not Found ")
return {}
The below is the serialized data method and it is erroring on the if self.privacy_page check which is the first occurrence of the model's foreign keys to the wagtailcore.Page in this serialized_data method

why none of the clients are getting a tray
I am working on a buffet simulation of a buffet. So basically the client will first go through the payment. Then he should go to get his tray which is the part that does not work. After, he should go get his food.
I dont understand why the Clients are not going to the tray queue.
In fact, right-now the client is paying and then he his going directly to tale his food without taking a tray so something must be wrong in the class function but I can't figure what.

when I use thread and win.Dispatch("SAPI.SpVoice") to make a book reader app i meet this question
my question is when i try to pause the speaker for a few minutes and i didn't do anything it will give me an error. Then i resume it, but it doesn't work.
I guess it might be a matter of releasing win.Dispatch("SAPI.SpVoice") from occupation.(For example, after a few minutes of idle he will automatically release the occupation)
is there anyone who can help me!!!
the error is there

How do you post form data using pytest?
I'm trying to write a unit test that posts form data. The actual line in question is:
def test_create_request():
with app.test_client() as test_client:
app_url = '/requests/'
with app.app_context():
new_request = get_new_request()
form_data = json.dumps(new_request, default=str)
print('FORM DATA: ', form_data)
resp = test_client.post(app_url, data=form_data, headers={'Content-Type': 'application/json'})
assert resp.status_code == 200
s = json.loads(resp.data)
assert s['success'] == True
Where new_request is a dict representation of an object. The print statement yields (I've formatted it a bit):
FORM DATA: {
"request_id": "6",
"state_id": 1,
"orig_project_id": "1",
"orig_project_code": "QQQ",
"orig_allocated_funding": "123.45",
"orig_ytd_spend": "123.45",
"orig_ytd_commit": "123.45",
"orig_ytd_ocnr": "123.45",
"new_project_id": 2,
"new_funding_amount": 123.45,
"new_ytd_spend": 123.45,
"new_ytd_commit": 123.45,
"new_ytd_ocnr": 123.45,
"plan": "this is the plan",
"reason": "this is the reason",
"sm_director": "sm.dir#example.com",
"submitted_by": "xfgbn#vexample.com",
"created_on": "2021-09-14 16:32:55",
"meets_approval_guidelines": null
}
In the flask form, most fields are required. When I try to post the data, the form.validate_on_submit() function in the view's route returns False, and the 2nd assert fails. WTForms claims that none of the required orig_allocated_funding, orig_ytd_spend, orig_ytd_commit, orig_ytd_ocnr, new_project_id, new_funding_amount, new_ytd_spend, new_ytd_commit, new_ytd_ocnr, reason, plan, sm_director, or submitted_by fields are supplied.
I've read several tutorials, and I can't see what I'm doing wrong. Can anyone help?
What I was able to make work was scraping form_data altogether: def test_create_request(): with app.test_client() as test_client: app_url = '/requests/' with app.app_context(): new_request = get_new_request() resp = test_client.post(app_url, data=new_request) assert resp.status_code == 200 s = json.loads(resp.data) print(s['html']) assert s['success'] == True
How to return connection from a JDBC connection class using Scala's exception handling?
I am trying to create a Scala JDBC program where a connection to Hive is being made. To do this, I wrote the below code.
var HIVECON: Connection = null
def hiveConnection(): Connection = {
val conf = new Configuration()
conf.set("hadoop.security.authentication", "Kerberos")
// DEV System Properties
System.setProperty("java.security.krb5.kdc", "ip-address.ec2.internal");
System.setProperty("java.security.krb5.realm", "DEV.COM");
// DEV System Properties
// DEV loginUserFromKeytab
UserGroupInformation.loginUserFromKeytab("username#DEV.COM", "/home/username/username.keytab");
// DEV loginUserFromKeytab
try {
Class.forName("org.apache.hive.jdbc.HiveDriver")
if(HIVECON == null || HIVECON.isClosed)
HIVECON = DriverManager.getConnection("jdbc:hive2://ip-address.ec2.internal:10500/dbname;principal=hive/ip-address.ec2.internal#DEV.COM", "username","password")
else HIVECON
} catch {
case s:SQLException => s.printStackTrace()
case e:Exception => e.printStackTrace()
}
}
But the code gives a compilation error at these lines:
With the way I wrote, the catch statements are returning UNIT where my method is trying to return CONNECTION. Is there any way to handle the exception better ?
I would handle the Exception in a functional way.
If you do not care about specific Exception use Option:
var HIVECON: Option[Connection] = None
def hiveConnection(): Option[Connection] = {
...
try {
Class.forName("org.apache.hive.jdbc.HiveDriver")
if(HIVECON == None || HIVECON.get.isClosed)
HIVECON = Some(DriverManager.getConnection("jdbc:hive2://ip-address.ec2.internal:10500/dbname;principal=hive/ip-address.ec2.internal#DEV.COM", "username","password"))
HIVECON // return Some(Connection)
} catch {
case s:Exception =>
s.printStackTrace()
None
}
If you care for the Exception use Try:
var HIVECON: Connection = null
def hiveConnection(): Try[Connection] = {
...
Try {
Class.forName("org.apache.hive.jdbc.HiveDriver")
if(HIVECON == null || HIVECON.isClosed)
HIVECON = DriverManager.getConnection("jdbc:hive2://ip-address.ec2.internal:10500/dbname;principal=hive/ip-address.ec2.internal#DEV.COM", "username","password")
HIVECON // return Success(Connection)
}
In case of a Failure it returns Failure(Exception).
