I'm using OpenFL and I'm attempting to use this code I found...
pos.sortOn("cotangent", Array.NUMERIC | Array.DESCENDING);
...but I'm getting the error:
src/Main.hx:180: characters 2-12 : Array<{ yPoint : Float, xPoint : Float, cotangent : Float }> has no field sortOn
src/Main.hx:180: characters 26-39 : Class<Array> has no field NUMERIC
src/Main.hx:180: characters 42-58 : Class<Array> has no field DESCENDING
Now according to this 'sortOn' is an available method for AS3 arrays so what is the problem?
In Haxe you could use ArraySort.
Something like here
Haxe has a builtin standard Array class, which is what you're referencing, not AS3's Array. The Haxe Array is documented here: http://api.haxe.org/Array.html
If you don't care about a stable sort, you can use the sort method: http://api.haxe.org/Array.html#sort

I'm trying to use PySpark's split() method on a column that has data formatted like:
[6b87587f-54d4-11eb-95a7-8cdcd41d1310, 603, landing-content, landing-content-provider]
my intent is to extract the 4th element after the last comma.
I'm using a syntax like:
mydf.select("primary_component").withColumn("primary_component_01",f.split(mydf.primary_component, "\,").getItem(0)).limit(10).show(truncate=False)
But I'm consistently getting this error:
"cannot resolve 'split(mydf.primary_component, ',')' due to data
type mismatch: argument 1 requires string type, however,
'mydf.primary_component' is of
structuuid:string,id:int,project:string,component:string
type.;;\n'Project [primary_component#17,
split(split(primary_component#17, ,)[1], \,)...
I've also tried escaping the "," using \, \\ or not escaping it at all and this doesn't make any difference. Also, removing the ".getItem(0)" produces no difference.
What am I doing wrong? Feeling a dumbass but I don't know how to fix this...
Thank you for any suggestions
You are getting the error:
"cannot resolve 'split(mydf.`primary_component`, ',')' due to data
type mismatch: argument 1 requires string type, however,
'mydf.`primary_component`' is of
struct<uuid:string,id:int,project:string,component:string>
because your column primary_component is using a struct type when split expects string columns.
Since primary_component is already a struct and you are interested in the value after your last comma you may try the following using dot notation
mydf.withColumn("primary_component_01","primary_component.component")
In the error message, spark has shared the schema for your struct as
struct<uuid:string,id:int,project:string,component:string>
i.e.
column
data type
uuid
string
id
int
project
string
component
string
For future debugging purposes, you may use mydf.printSchema() to show the schema of the spark dataframe in use.

select from list by index ${locator_var} ${inp_msge_type}
--getting error as expected string, int found
select from list by index ${locator_var} 7
-----not getting any error
${inp_msge_type}----contains 7 from DB query the result is stored in this variable, to avoid hard coding we need to do this
Is there any way to write
Do not add links to screenshots of code, or error messages, and format the code pieces accordingly - use the ` (tick) symbol to surround them.
The rant now behind us, your issue is that the keyword Select From List By Index expects the type of the index argument to be a string.
When you called it
Select From List By Index ${locator_var} 7
, that "7" is actually a string (though it looks like a number), because this is what the framework defaults to on any typed text. And so it works.
When you get the value from the DB, it is of the type that the DB stores it with; and probably the table schema says it is int. So now you pass an int to the keyword - and it fails.
The fix is simple - just cast (convert) the variable to a string type:
${inp_msge_type}= Convert To String ${inp_msge_type}
, and now you can call the keyword as you did before.
I have written a function which generate a TimeStamp and convert it to a String using toString(). I want to remove the whitespaces and other special character from that string. Is there is any efficient way to do it ?
This is a function which generate ID using TimeStamp , since timestamp will be unique (Note : When IDs are generated at different M.Sec)
fun autoGenerateID() : String = Timestamp(java.util.Date().getTime()).toString()
When I call the function, It should return :
20190612121912463
But the produced result was :
2019-06-12 12:19:12.463
I would suggest dropping the use of Timestamp class. it is outdated and anything it provides can be achieved in easier ways.
For your use case you could just use the SimpleDateFormat. It would look like this:
SimpleDateFormat("yyyyMMddHHmmssSSS").format(Date())
I am trying to validate number value which will include integer as well as float values. Following is my implementation for the same.
Joi Schema.
const numcheckschema = Joi.object().keys({
v1:Joi.number().empty("").allow(null).default(99999),
v2:Joi.number().empty("").allow(null).default(99999),
v3:Joi.number().empty("").allow(null).default(99999)
})
Object
objnum={
v1:"15",
v2:"13.",
v3:"15"
}
objValidated = Joi.validate(objnum, numcheckschema);
console.log(objValidated);
When i execute the above mentioned code I get an error
ValidationError: child "v2" fails because ["v2" must be a number]
as per the documentation when we tries to pass any numeric value as a string it converts the values to number but here in this case my value is 13. which is not able to convert into number and throwing an error.
Is there any way by which we can convert this value to 13.0
You can use a regex in order to match numbers with a dot, for instance:
Joi.string().regex(/\d{1,2}[\,\.]{1}/)
And then combine both validations using Joi.alternatives:
Joi.alternatives().try([
Joi.number().empty("").allow(null),
Joi.string().regex(/\d{1,2}[\,\.]{1}/)
])
However, I think you may need to convert the payload to number using Number(string value). You need to check the payload type, if it isn't a Number, you need to convert it.
If you want to know more about the regex used in the example, you can test it in here: https://regexr.com/
I am trying to define GraphQL schema like this:
type Obj {
id: Int
0_100: Int
}
But it gives following exception.
'GraphQLError: Syntax Error: Expected Name, found Int "0"',
How can I define attribute starting with numeric, -, + signs.
This is the regexp for names in GraphQL: /[_A-Za-z][_0-9A-Za-z]*/. Anything that does not match is not allowed.
Sample URL:
http://facebook.github.io/graphql/June2018/#sec-Names
Numerical parameter names do not work in GraphQL.
You can probably prefix it with a string like _0_100, but it's fairly unusual and I'd recommend against it. Consider using words to name your parameters instead.
