I have the list of all countries. When I need to get the list of English speaking countries i do:
Country.objects.filter(lang='English')
Which works great. However, I want to let say have US and Canada to show up at the start of the list at all times, as my primary focus is in North America.
Now, should I do the query in a custom manager and remove the two countries from the list and insert them at the start or should I have a template tag that takes a list and returns a rearranged list.
It would have been nice to have used sort_by to do this, and I don't mind to overwrite some function to get the job done.
Sample code is appreciated.

I have a Google sheet with multiple sheets.
The Ambassador users sheet has a list of multiple users (ID, Email, Coupon, and three more irrelevant columns).
Each new user is updated to the sheet via Zapier.
I can have three users with coupon 1234, four with ABCD and two with XYZ.
I then create a unique sheet for each type of coupon (also via Zapier) and want to update each sheet only with the users that have the correct coupon for that sheet.
The coupon is also listed in cell J1 on each sheet.
I need the update to happen automatically without pressing any buttons.
I do not know how to use the functions on Google sheets (I understand it's different from VBA), and I though using a function would be the best solution.
I tried using the IF function in conjunction with the INDEX function and it worked, however, it requires me to copy the function into each row, and thus reduces the automation option.
=if('Ambassador users'!$C3=$J$1, index('Ambassador users'!A3:G3),"")
Then I tried to use the IMPORTRANGE function, and this worked, but not in conjunction with the IF
=if('Ambassador users'!$C2=$J$1, importrange("1QHGSCR_pVepNlMtjFshvGnI-vSPzgqi3g9jz98","'Ambassador users'!A2:G11"),"")
This gave me all the rows in the Ambassador users sheet.
I think I'm doing something wrong with the IF statement in the initial range I'm setting is wrong.
I also tried to set a range in the IF, but that totally didn't work.
try like this with ARRAYFORMULA:
=ARRAYFORMULA(IF('Ambassador users'!C3:C=J1, 'Ambassador users'!A3:G, ))
or perhaps FILTER:
=FILTER('Ambassador users'!A3:G, 'Ambassador users'!C3:C=J1)
I´ve created a list in SharePoint. What i´ll like to do is create another list, and retrieve some information from one list to my new one, and be able to change the input data from list A in a single line of text.
So lets say, list A is PopStar, with columns like Genre "Rock", HairColor "Red" and GrammyCount "2".
In list B i only want textboxes to show whats in list A and be able to change (update) them, for example Genre to "Pop", HairColor to "Black" and GrammyCont to "8" ?
Is this possible?

In order to achieve exactly what you want you will require either a Workflow or an Event Receiver, however I assume you won't feel confident by struggling with such approaches, furthermore, there are some workarounds that could be very close to your requirement and maybe are even better solutions than the approach you suggest, in terms of maintenance, growth and upgrade.
I suggest to review topics like "SharePoint parent/child list webparts connections" or "sharepoint edit form add child items", here are two videos of which you can get some ideas.
https://www.youtube.com/watch?v=9PWIxk6rF-A
https://www.youtube.com/watch?v=-5CdjfLONgE
Take in count that you can do more than what is displayed in the videos, by example in the Edit Form you could add a webpart to display the Quick Edit View (Grid View) of the related list so the values can be edited in the same Form and thus removing the need to navigate to a second window.
So I have a DB structure like so: (ignore how i named things its a quick fake DB example things)
Collection: id, ...
List: id, title,...
Car: id, name, ...
CollectionHasList: id, collectionid, listid
ListHasCar: id, carid, listid
So what I am trying to do is in the django admin panel under collection/add I want to be able to fill in all of these tables instead of filling everything in individually one by one.
So the collection fields will exist as normal, but then I want to have a custom field that takes in a list title and a text area that takes in a comma delimited cardIds (cards are already created and don't need to be done through here, just list and collections) But since Collections have many lists, I want to be able to click a "add" button and generate the same custom form again to add more lists (with associated cars).
I think in the model I will be able to do the custom saving that I need, but I can't get the form to work and thats what I need most help on. Can anyone please help me! Thank you so much! I looked everyone on stack overflow and haven't found anything that can directly help me, some good points, but I still can't put it together.
Is it possible to choose only specific items from the list in selectOneMenu?
For example. I have List Products has many fields like name, id etc. One of it is category (1,2 or 3) I want to have only one category in the selectOneMenu without making new Lists and new classes. Can you help me?
I think the easiest way is to set the value attribute of f:selectItems to a method which filters your original collection.
Otherwise you'd have to implement your own version of f:selectItems which allows filtering - as we once did in one of our projects.
Assume that I have a list of employee names from a database (thousands, potentially tens-of-thousands in the near future). To make the problem simpler assume that each firstname/lastname combination is unique (a big if, but a tangent).
I also have a RSS stream of news content that pertains to the business (again, could be in the hundreds of items per day).
What I would like to do is detect if an employees name appears in the several paragraph news item and, if so, 'tag' the item with the person its talking about.
There may be more than one employee named in a single news item so breaking the loop after the first positive match isn't a possibility.
I can certainly brute force things: for every news item, loop over each and every employee name and if a regex expression returns a match, make note of it.
Is there a simpler way in ColdFusion or should I just get on with my nested loops?
Just throwing this out there as something you could do...
It sounds like you'll almost unanimously have significantly more employee names than words per post. Here's how I might handle it:
Have an always-running CF app that will pull in the feeds and onAppStart
Grab all employees from your db
Create an app-scoped look up struct with first names as keys and a struct of last names as values ( you could also add middle names sibling to last names with a 3rd tier if desired ).
So one key in the look up might be "Vanessa" with a struct with 2 keys ( "Johnson" and "Forta" ) as its value.
Then, each article you parse, just listToArray with a space as a delimiter and loop through the array doing a simple structKeyExists with each token. For matches, check the next item in the array as a last name.
I'd guess this would be much more performant processingwise than doing however many searches and also take almost no time to code and you can feed in any future sources extremely simply ( your checker takes one argument, any text on Earth ).
Interested to see what route you go and whether your experiments expose anything new about performance in CF.
Matthew, you have a tall order there, and there are really multiple parts to the challenge/solution. But just in terms of comparing a list of values to a given set of text to see if one of them occur in there, you'll find that there's no one could CF function. BEcause of that, I created a new one, findList, available at cflib:
http://cflib.org/index.cfm?event=page.udfbyid&udfid=1908
It's not perfect, nor as optimal as it could be, but it may be a useful first step or you, or give you some ideas. That said, it suited my need (determine if a given blog comment had reference to any of the blacklisted words). I show it comparing a list of URLs, but it could be any words at all. Hope that's a little helpful.
Another option worth exploring is leveraging the Solr engine that ships with CF now. It will do the string search heavy lifting for you and you can probably focus on dynamically keeping your collections up to date and optimized as new feed items come in.
Good luck!
