I am fairly new to Redis and RedisJson and I have been through all the documentation I can get my hands on, but I still can't seem to figure this one out. I am hoping someone could shed some light on this situation to help me understand. My end goal is to be able to remove the JSON object from the responses array using JSON.ARRPOP. I need to get the index of the object first and I can't seem to do that.
Here is my object structure:
JSON.SET test:1 $ '{ "responses":[{"responseId":"29aab59c-10b0-48c0-ab91-8873fb6e2238"},{"responseId":"ab79f09b-8e31-41f4-9191-ef89a34964d3"}]}'
Check the path:
JSON.GET test:1 $.responses[*].responseId
RETURNS:
"["29aab59c-10b0-48c0-ab91-8873fb6e2238","ab79f09b-8e31-41f4-9191-ef89a34964d3"]"
Ok looks good I have an array of two strings lets get that index of 29aab59c-10b0-48c0-ab91-8873fb6e2238.
JSON.ARRINDEX test:1 $.responses[*].responseId '"29aab59c-10b0-48c0-ab91-8873fb6e2238"'
RETURNS:
(nil)
(nil)
It appears to have searched but found nothing?
At first I thought it was an escape character issue but I get the same results with responeIds as integers 1 and 2.
Any help here would be greatly appreciated. Thanks!
JSON.ARRINDEX can only search for scalar values. Objects and arrays are not scalars so you can't search for them.
For your use case you should look at https://redis.io/docs/stack/search/indexing_json/

I'm just starting out with thMap.
So far I have successfully mapped an X12 835 message to output structures. That works no problem.
I have also successfully acquired the LoopIndex of the current loop using the LoopIndex() function.
My challenge:
I need to get the value of an element from the enclosing loop.
In the attached image, everything in green is working.
I'm trying to get the value down the red line.
My goal is to do this assignment
gsRecord.parent_id = enclosing loop isaRecord.id
The documentation explains some things but I don't see examples putting it together.
Does anyone have any good examples, videos or suggestions?
Update from 12/9/22
Here is something I have tried. Providing this example in hopes someone recognizes a specific issue to help move me forward. Any input would be appreciated.
Per this screenshot
I am attempting to output in gsRecord.parent_id the loopIndex of the parent loop (isaRecord).
This gives me the following error
"An reference in an LoopIndex/Variable was made to an either an input
map element or an output map element that is not in the context of the
reference. Use an enclosing looping output map element here.(msg #1202)"
Given the reference to 'enclosing looping output map element here' it feels like the gsRecord is not properly defined as a child of the isaRecord.
However the definition of the gsRecord is in reference to the isaRecord as in this screenshot.
It feels like there is some combination of LoopIndex and EnclosedContext that I could use to accomplish this but I'm unable to find any in-depth documentation on the functions.
Any help would be appreciated.
I am trying Drools excel to compare some values of products like I have P1,P2,P3...P10 Now I am comparing it with incoming value from request.
I tried in below way but I am receiving an error.
Can you please help to fix this issue. Hope I am making a simple mistake but not able to find it.
Thanks in advance.
You have too many parentheses.
The value in the product column is substituted as is into $param. The correct syntax we're looking for is ... in ("P1", "P2"); however you've provided ("P1", "P2") as the product value. This transforms to in (("P1", "P2")), which is not correct.
Remove the parentheses from the product cell: "P1", "P2".
In jasper I have to print a collection without knowing in advance the keys, because they are programmatic and can change over time. Let me do an example of this list:
formData[0]={addictions=1, workout=0, allergies=1, selfSufficiency=0}
formData[1]={gastricNose=1, weightChange=1, diet=XXXX}
[...]
formData[12]={dailyAmount=12, latestDate={type=date, value=1542582000000}, ostomy=1, ostomyType=AA, ostomyBag=BB}
How can I print a list of all these keys/values so that they get all listed properly like this? I can already print these objects raw in a list but they obviously look pretty much like the example I wrote above, while instead I need jasper to cycle through each of the elements by itself and retrieve the keys and the value for each element.
This is what I'm trying to print:
addictions: 1
workout: 0
[...]
gastricNose: 1
weightChange: 1
[...]
dailyAmount: 12
latestDate: 18/11/2018
[...]
In all posts I've looked into I'm required to know at least the name of the keys, but in my case I can't. And I cannot modify the data source structure either (for instance formatting the collection to be {key:"addictions",value:"1"} can't do that).
Thanks for your hints
Is there a neat way of looking up the key of a dictionary by an atom value if that atom is inside a value list ?
Assumption: The value lists of the dictionary have each unique elements
Example:
d:`tech`fin!(`aapl`msft;`gs`jpm) / would like to get key `fin by looking up `jpm
d?`gs`jpm / returns `fin as expected
d?`jpm / this doesn't work unfortunately
$[`jpm in d`fin;`fin;`tech] / this is the only way I can come up with
The last option does not scale well with the number of keys
Thanks!
You can take advantage of how where operates with dictionaries, and use in :
where `jpm in/:d
,`fin
Note this will return a list, so you might need to do first on the output if you want to replicate what you have above.
Why are you making this difficult on yourself? Use a table!
q)t:([] c:`tech`tech`fin`fin; sym:`aapl`msfw`gs`jpm)
q)first exec c from t where sym=`jpm
You can of course do what you're asking:
first where `jpm in'd
but this doesn't extend well to vectors while the table-approach does!
q)exec c from t where sym in `jpm`gs
I think you can take advantage of the value & key keywords to find what you're after:
q)key[d]where any value[d]in `jpm
,`fin
Hope that helps!

The answers you have received so far are excellent. Here's my contribution building on Ryan's answer:
{[val;dict]raze {where y in/:x}[dict]'[val]}[`msft`jpm`gs;d]
The main difference is that you can pass a list of values to be evaluated and the result will be a list of keys.
[`msft`jpm`gs;d]
Output:
`tech`fin`fin
I am new to python.I am posting here for the first time and I know question might be quite basic but problem is I can't figure out myself.
Lets say I have
List=[("a,"b"),("c","d"),("e","f")]
I want the user to enter one of the elements of one of the tuples as input and the other element is printed.Or more precisely I would say that just one of elements in List[x][0] is input and corresponding List[x][1] element is printed as output.I hope it makes sense.
Thanks!
Please check List in the question.I think you forgot a quote(") in the first tuple.[("a^here,"b"),("c","d"),("e","f")]
I think this might help you.
List=[("a","b"),("c","d"),("e","f")]
c=raw_input('ENTER A CHARACTER-')
for i in xrange(len(List)):
if c in List[i]:
ind=List[i].index(c)
print List[i][abs(ind-1)]
break
