Can someone explain to me what the difference is between these two Cloud Functions declarations!?
exports.boxScoresUpdate = functions.database.ref('/Games/{gid}/BoxScores').onWrite(event => {
and
exports.emailEmployeeReport = functions.database.ref('/Employee/${eid}/reports').onWrite(event => {
Other then they reference different Nodes... the first function just has {gid} while the second function has ${eid}
What is the $ used for!? and does it actually matter (can you use them interchangeably) since my function works without the $ as seen in the first database reference using only {gid}
The first line is the correct expression for a wildcard variable in a database path.
The second line doesn't seem to be correct at all. If it was using string variable interpolation with backticks (which it is not), it would include the current value of eid in the string, assuming it has been defined globally ahead of time. Right now it is literally including the $ in the string path, which is most likely not what was intended.
If you got that line from this video, notice in the comments that we acknowledged that is was a mistake in the typing and should not have included the dollar sign.

Let me preface this by stating very clearly that I am not a developer and I'm new to NetSuite formulas.
I have a NetSuite saved search that include the Web Address (field id: {url})
I need to remove everything except the main part of the domain (end result should look like abc.com).
I have attempted to use REPLACE({url}, 'http://[,' ']) unsuccessfully.
I have also attempted various LTRIM, RTRIM, TRIM formulas without luck.
I found some information on using REGEXP_SUBSTR, but wasn't successful there either.
I was able to accomplish my goal in Excel using Excel string functions MID, LEN, and RIGHT, but that doesn't seem to translate in NetSuite.
I'd love some assistance.
REGEXP_SUBSTR({url}, '//(.)+') --> get substring starting with //
REPLACE({text}, '/') --> replace / with nothing
The final formula is:
REPLACE(REGEXP_SUBSTR({url}, '//(.)+'), '/')
Jala's answer doesn't seem to work for URLs such as https://stdun7.wixsite.com/stdunstansparish where it returns stdun7.wixsite.comstdunstansparish
In your saved search create a Forumula (Text) field with the following formula
REGEXP_REPLACE({url},'(^http[s]?://)([a-zA-Z0-9.-])(/?.)', '\2')
I'll break down the arguments for the REGEXP_REPLACE function and how it all works...
First argument - {url} the Field containing the url information to parse
Second argument - regexp string
Third argument = replace regexp string
the regexp string has parentheses to denote capture groups of portions of the regular expression.
The first capture group captures the protocol portion of the URL.
The second capture group captures the next part, all permissible hostname characters until the end of the string, or until a '/'
The third capture group captures the remaining portion of the string.
The replace string is used to prepare the return value of the REGEXP_SUBSTR function. Since the entire url is matched by the regexp, the entire string will be replaced by this expression, referencing the second capture group. (aka the hostname)
Since you say you're new to NetSuite formulas, I'll note that those functions are based on Oracle PL/SQL so if you want additional info or examples of how they work beyond what NetSuite provide, sometimes it's instructive to just google things like "pl/sql REGEXP_SUBSTR" etc. to get additional documentation how how they work.
Another good resource is regex101.com, a helpful site to test regular expressions in advance....
I am trying to create a function within my rule sets that will check that a particular document's field is null. Unfortunately one of the variables I pass in has a leading slash. For example: /mycollection/xyz123
rules_version = '1';
function hasNullStartDate(teamGuid, path) {
return get(/databases/$(database)/documents/team/$(teamGuid)/$(path)).data.startDate == null
}
match /teams/{teamid}/{subpath=**} {
allow delete: if hasNullStartDate(teamid, subpath)
}
I have tried removing the slash between my two variables $(teamGuid)$(path) but that causes a syntax error in the rules.
I have tried to do .replace() on the path, but that has ended up in a run time error. Maybe I didn't format it right or maybe it has to do with the rules version.
https://firebase.google.com/docs/reference/rules/rules.String#replace
How can I get rid of that leading slash /?
So I think you don't want to use replace at all in this specific case, since a Path object (what you're passing to get()) isn't actually a string. I think you'll be better off with a string split to get "mycollection" and "xyz123" into separate elements so you can build the path using their values individually.
Either that, or you can build the entire string the way you would expect for a normal string, and pass that string to path() to then pass to get(). Again, see the Path documentation for more on that.
I'm writing a Gatling simulation, and I want to verify both that a certain element exists, and that the content of one of its attributes starts with a certain substring. E.g.:
val scn: ScenarioBuilder = scenario("BasicSimulation")
.exec(http("request_1")
.get("/path/to/resource")
.check(
status.is(200),
css("form#name", "action").ofType[String].startsWith(BASE_URL).saveAs("next_url")))
Now, when I add the startsWith above, the compiler reports an error that says startsWith is not a member of io.gatling.http.check.body.HttpBodyCssCheckBuilder[String]. If I leave the startsWith out, then everything works just fine. I know that the expected form element is there, but I cant confirm that its #action attribute starts with the correct base.
How can I confirm that the attribute start with a certain substring?
Refer this https://gatling.io/docs/2.3/general/scenario/
I have copied the below from there but it is a session function and will work like below :-
doIf(session => session("myKey").as[String].startsWith("admin")) { // executed if the session value stored in "myKey" starts with "admin" exec(http("if true").get("..."))}
I just had the same problem. I guess one option is to use a validator, but I'm not sure how if you can declare one on the fly to validate against your BASE_URL (the documentation doesn't really give any examples). You can use transform and is.
Could look like this:
css("form#name", "action").transform(_.startsWith(BASE_URL)).is(true)
If you also want to include the saveAs call in one go you could probably also do something like this:
css("form#name", "action").transform(_.substring(0, BASE_URL.length)).is(BASE_URL).saveAs
But that's harder to read. Also I'm not sure what happens when substring throws an exception (like IndexOutOfBounds).
I am using Handlebars templates. If I want to insert a variable in an hbs file, I add it as {{var_name}}.
The issue is, I have a large object with its keys taking formats similar to:
{
"stats.name":"John",
"stats.performance.day":123,
"stats.performance.month":4567,
"company":"My LLC"
}
If I try to add these to the Handlebars file as {{company}}, {{stats.name}}, {{stats.performance.day}}, {{stats.performance.month}} then only the {{company}} will be displayed. All other values come out blank, I assume because "." is a special character in Handlebars.
My question is, is there a way to override this, or do I actually need to iterate through this object and change every "." to a "_" or something before passing it to Handlebars to make it work?
I would recommend renaming your properties. Dot Notation is one of the two ways to access object properties in JavaScript. Typical code would look like: obj.prop. If your object's keys are not valid identifiers, then you must use Bracket Notation: obj['my-prop']. Since a dot is a property accessor, it is very unusual to see one in a property name. If I were to come across code written as obj['stats.performance.date'], I would assume it was a mistake and that obj.stats.performance.date was intended.
With that said, Handlebars does support referencing properties that are not valid identifiers. This is called "segment-literal-notation", and it is as simple as wrapping square brackets around your identifier:
{{[stats.performance.day]}}
The documentation also states that:
JavaScript-style strings, " and ', may also be used vs. [ pairs.
So the following alternatives are valid:
{{"stats.performance.day"}}
{{'stats.performance.day'}}
I am trying to find entities (Tags) in the database via their Name property, where it is important to ignore the case (When database is searched and the Database contains a Tag with the name Database, that one should be returned). Right now, my code looks like this:
public IEnumerable<db.Tag> FindByNames(IEnumerable<string> tagNames)
{
return this.DatabaseContext.Tags
.Where(tag => tagNames.Contains(tag.Name));
}
Obviously, this one is case sensitive. I have tried to provide StringComparer.OrdinalIgnoreCase as comparer to the Contains method, but got a warning during execution that the expression could not be translated and would be executed in code rather than in the database (I don't remember the exact message, I will edit as soon as I am back on my development machine). I can live with that if I have to, but it would be nice to know how to let the database do the work in this case. Is it possible?
No change should be necessary. SQLite's "LIKE" is already case-insensitive.
The default behavior of the LIKE operator is to ignore case for ASCII characters.
(cref https://www.sqlite.org/pragma.html#pragma_case_sensitive_like and Case sensitive and insensitive like in SQLite)
Of course, you can always use .FromSql() to get the exact query you want. Example:
context.Tags.FromSql("SELECT * FROM tags WHERE name LIKE '%{0}%'", tagName)
