And in addition to all of that, one of the workarounds people seem to like using is to have things comma-separated and enclosed in " to make sure it's getting the right commas, but I'm working on ERP software for the millwork industry in America. We're still allergic to metric here, and we use " to mean inches and ' to mean feet, so we can't use those either!
I know it's odd, but I've had three separate companies ask me for data formatted this way in the past couple of years. I'm not sure why, other than that the pipe is less common to run into within the data than commas.
We have had a few people ask for a CSV using a pipe as a separator. If you run into that and need to open it in Excel, you do that by going to the data tab, then click From Text/CSV. It may detect the separator character automatically, but if not there is a place where you can set it. (You may want to right click on the GIF and open in new tab if it's too fuzzy.)
@Stephen Canzano , when you are testing you can also manually define %request and give it a body and whatever else it needs before you call your class method. For instance:
set %request = ##class(%CSP.Request).%New()
set %request.ContentType = "application/json"
set %request.Method = "POST"
set %request.Content = ##class(%CSP.CharacterStream).%New()
set json = {}.%New()
set json.firstname = "David"
set json.lastname = "Hockenbroch"
do %request.Content.Write(json.%ToJSON())
Then you can call your class methods and the %request object you usually manipulate in those methods will be defined.
@Evgeny Shvarov it's like this:
try{
//Do things here
}
catch ex{
do ex.Log()
return ex.AsStatus()
}If you do this, then the error gets logged in the application error logs in the system management portal, and a JSON representation of the exception gets returned through the API.
I'm not 100% certain, but I think you could use:
set osuser = ##class(%SYS.ProcessQuery).%OpenId($J).OSUserName
set userprofile = "C:\Users\"_osuserYou can create and log exceptions so that they show up in the application error logs in the SMP. That's how I prefer to do things.
@Theo Stolker I'm not sure what you mean by, "I never liked the different behavior of embedded sql, like when you have no result, you have no easy way to find that out." When you run an embedded query, it sets a variable called SQLCODE. If SQLCODE = 0, query completed with results. If SQLCODE = 100, query completed with no results. If SQLCODE < 0, there was an error with the query.
FYI, in your "Building SQL In Strings" section, you can also still use %SQL.Statement like this:
set stmt = ##class(%SQL.Statement).%New()
// Note the question mark in the query.
set query = "SELECT Name, Age FROM Patient WHERE ID=?"
set sc = stmt.%Prepare(query)
// You can add error handing here if the above status results in an error
// Providing variables to the %Execute method will insert them where the question marks are in the query, in order
set rs = stmt.%Execute(id)Really you'd want to set a variable equal to the $TLEVEL at the start of your try, then in the catch calculate the difference between the starting $TLEVEL and the current $TLEVEL, then do that many TROLLBACK 1s.
Combining what you said about error handling and transactions and also returning a status, a very basic outline for a lot of methods could be something like:
try{
TSTART
//Do stuff here
TCOMMIT
return $$$OK
}
catch ex{
if $TLEVEL > 0{
TROLLBACK
}
return ex.AsStatus()
}Some of us who write articles could do a better job of making this easier for you too, though. We like to use short forms of certain things, like {} and [] which are ##class(%Library.DynamicObject) and ##class(%Library.DynamicArray). I try to remember to use the latter in my articles just because it makes it easier to find the thing I'm talking about in the documentation. There are cases like that which are technically correct, but make it harder for beginners to learn.
I'm not sure why you're getting that error, but the Collection keyword is deprecated. You are already declaring the property as a list, so it should be unnecessary anyway.
Your NewsGetItem method has two parameters, version and id, but the route you have defined for it only has one parameter, id. The parameter lists need to match up and be in the same order. Try taking the version parameter our of the NewsGetItem class method.
In this case, you'd probably have to create a class method in ObjectScript that changes the namespace, then call it using classMethodVoid() from the IRIS native SDK. But you'd have to make sure the necessary class method exists in all of the namespaces you want to change to and from, including %SYS.
I just now took a closer look at this because of a comment made on one of my ideas on the idea portal, and that's great news for us! Our software is an ERP system, and we have some customers who have multiple locations that they sell things out of. We generally have them share one code database, but different global databases. The old way, where it stored the table tuning statistics with the code, made it unusable for us because each of those locations would have different orders, invoices, customers, etc., so tuning the table would help one namespace and potentially harm the others!
In ObjectScript, you would do:
new $NAMESPACE
set $NAMESPACE = "USER"In embedded Python, you can execute those commands using iris.execute:
import iris
iris.execute('new $NAMESPACE')
iris.execute('set $NAMESPACE = "USER"')I am not far enough into embedded Python to know if that's considered a best practice or if there's another way, but it does work. Here are my results in a Python shell terminal session:
>>> print(iris.system.SYS.NameSpace())
USER
>>> iris.execute('new $NAMESPACE')
>>> iris.execute('set $NAMESPACE = "%SYS"')
>>> print(iris.system.SYS.NameSpace())
%SYSThis seems to work for positive posix times, but I'm not sure why the 846,976 microsecond offset is required. Maybe someone who understands this subject better can answer that one. All math, though, no string manipulation.
set newposix = ##class(%Library.PosixTime).LogicalToDisplay(posix-(posix#1000000)+846976)There are some naming conventions in the documentation already. Here's one example. I think there used to be more. I know there was one for Zen pages that suggested naming methods based on what was client side or server side or a Zen method. I thought there was also one that explained how things were named in the system classes, but I can't find that one in the current documentation.
I have no strong opinion about whether they are (or were) right or wrong. I think we just need to be aware that some of these are still out there, and people may be using them.
Vachan, that depends in part on what exactly you are doing in the terminal at the time. If you are running a method or routine that includes logging an exception, that will happen in the terminal just like it would anywhere else.
Just FYI, your link is broken. Here's a fixed one.
Thank you for the advice! I will try to learn about all of those things so I can improve this.
You are correct. I have removed it.
Yes, they should all be zservice. I believe I've fixed them! Thank you.
You can log the exception in your catch block for exactly the result you're looking for, if I understand your request correctly.
try{
//Your code here.
}
catch ex{
//The below line will add the exception to the application error log.
//Code will continue to execute after the catch block.
do ex.Log()
}Ronald, if that's your exact code, it may be because you have it as %Request instead of %request, lowercase r. Because %Request is undefined, it can't tell you whether %Request.Data("action",1) is undefined or not. Try it with %request.
It is available in my 2018.1.2 version.
As a point of clarification, property names ARE case sensitive in ObjectScript, but in SQL, column names ARE NOT case sensitive. You aren't allowed have a property named "name" and a property named "Name" because they would be ambiguous when doing SQL queries.
Versions that old used to install all the documentation locally. I forget what options had to be selected in the installer because it's been a while, but if you run it, you should have the option somewhere. Then you should be able to click the Cache icon in your system tray and click on "Documentation".
Do you mean the format as in HL7, FHIR, etc.? There are specific ContentType settings for those in the specification, I believe.
In the %SYS namespace, you can query the table Security.Applications and check the type column. If you do this in the system management portal in display mode, the Type column will start with "System". In logical mode, though, it will be a number. 1 is System, 2 is CSP Application, 4 is a privileged routine application, and 8 is a client application, and if an application is more than one of those things, the Type column is their sum. For example, if it's a System applcation AND a CSP application, the type will be 3. That complicated things, but fortunately since the 1 is the only odd number and it signified system applications, we can use the modulus function to identify system applications as follows.
select * from security.applications where {fn MOD(type,2)} = 1Also, at the risk of self-promotion, I wrote an article detailing more about managing applications programatically a while back. You can find it here.
