QUESTION
SELECT xText.query (' let $planes := /planes/plane
return
{
for $x in $planes
where $x/year >= 1970
order by ($x/year)[1]
return ($x/make, $x/model,$x/year )
}
')
FROM planes
ANSWER
Answered 2022-Mar-24 at 12:03The [1] is a predicate that is selecting the first item in the sequence. It is equivalent to the expression [position() = 1]. A predicate in XPath acts kind of like a WHERE clause in SQL. The filter is applied, and anything that returns true is selected, the things that return false are not.
When you don't apply the predicate, you get the error. That error is saying that the order by expects a single item, or nothing (an empty sequence).
At least one of the plane has multiple year, so the predicate ensures that only the first one is used for the order by expression.
QUESTION
I'm converting some old sql select statements to linq, and I've hit a stupid moment. The database is fixed so bad designs are permanent.
The sql statement is this;
WHERE xTD.Transaction_Type IN (9,10,11,12,19)
so I coded
List transTypes = new List() {9,10,11,12,19};
with a where clause of
where transTypes.Contains(xTD.Transaction_Type)
the problem is that xTd.Transaction_Type is a nullable field. What's the syntax to make this work?
Sorry but it's Friday and I can't even get google to find an answer.

QUESTION
I am new to Django and was working on my blog site to include a comment feature by using django-comments-xtd package.
I was following the tutorials specified on "https://django-comments-xtd.readthedocs.io/en/latest/tutorial.html", but it kept giving me an error saying "DoesNotExist at /comments/post/" whenever I tried to submit any comment
This is comment section code from my blog template from DetailView:
...ANSWER
Answered 2021-May-25 at 06:49As stated in the second point in the quickstart guide [django-comments-xtd Docs] of the package you use:
Enable the “sites” framework by adding
'django.contrib.sites'toINSTALLED_APPSand definingSITE_ID. Visit the admin site and be sure that the domain field of theSiteinstance points to the correct domain (localhost:8000when running the default development server), as it will be used to create comment verification URLs, follow-up cancellations, etc.
You need to enable the sites framework, set the SITE_ID setting and make sure the domain is correctly saved. To do this as referred in Django's documentation (linked in above quote):
Add 'django.contrib.sites' to your INSTALLED_APPS setting.
Define a SITE_ID setting:
QUESTION
I'm setting up comments in Wagtail using django-comments-xtd and one thing I'm having trouble figuring out is why my comment permalinks keep going to https://example.com/news/bloggy-test-post/#c1 instead of https://localhost:8000/news/bloggy-test-post/#c1.
I found a user with a similar issue in the Wagtail Google group who discovered that they had "example.com" set as their site in Wagtail admin. But I have only one site in my settings and it's currently set to "localhost" with a port of 8000.
Screenshot of the Wagtail admin site showing there is one site set to localhost with a port of 8000
I searched all my files and libraries for "example.com" and the only other setting I found was the BASE_URL setting in base.py. I tried changing that to http://localhost:8000 and the comment permalinks are still being directed to "example.com".
Is there another setting I'm missing? Or another way I'm supposed to get the URL?
Currently, I have this code for grabbing the url in my models.py file:
...ANSWER
Answered 2021-May-12 at 01:27Django has its own optional Sites framework which is distinct from Wagtail's concept of sites. In the standard Wagtail project template this is turned off (i.e. django.contrib.sites is left out of INSTALLED_APPS) but your project may have it enabled, particularly if you integrated Wagtail into an existing Django project. Like Wagtail, Django's site records are kept in the database, and I suspect this is where the example.com reference is hiding - if you have the Django admin site enabled (as distinct from the Wagtail one), you should find a Sites model listed in there.
Digging into the django-comments-xtd and django-contrib-comments code shows that the URL returned by the {% get_comment_permalink %} tag is ultimately handled by the django.contrib.contenttypes.views.shortcut view, which is indeed listed as making use of the Django sites framework.
As for why adding a second Wagtail site circumvents the problem: when Wagtail generates page URLs, it will prefer to return local URLs without the domain (e.g. ) when it can do so unambiguously - as is the case when only one Wagtail site is defined. Once you add a second site, it switches to a full URL including the domain - and at that point, Django recognises that it's been passed a full URL and doesn't try to apply its own site logic to 'fix' it up.
QUESTION
Actually started using django-import-export latest version. Wanted to know where exactly we can override to skip certain rows of the csv from being imported based on current user or the domains from a list of domains he can import data from the csv. How exactly to customize which of the methods to override and how?
In my ModelResource, I have created the list of domains for the current user, and which method of the import-export do I check this and skip the rows from being imported?
class MailboxResource(resources.ModelResource): mdomain_list = []
...ANSWER
Answered 2020-Nov-09 at 09:01You can use the skip_row(...)--(Doc) method, as you mentioned.
But, the skip_row(...) method doesn't provide any hooks to the request.user, so, we are doing a simple hack to get the requested user in skip_row() by overriding the import_data(...)
QUESTION
Django==3.0.8
django-comments-xtd==2.6.2
views.py
...ANSWER
Answered 2020-Jul-30 at 09:28In your INSTALLED_APPS,in settings.py, If django.contrib.auth is above your app, DJANGO will render the default auth , So what you should do is place your app above the django.contrib.auth so that DJANGO will render yours first.
That works for me
