I have CSV that is parsed with Papaparse and the output is the following:
[
{
"id" : 1,
"title" : "Test1"
},
{
"id" : 2,
"title" : "Test2"
}
]
And I need to receive the following instead:
[ //also could be without this
{
"id" : 1,
"title" : "Test1"
} //without the comma
{
"id" : 2,
"title" : "Test2"
}
] //also could be without this
Is there a way to directly remove that comma that separates two records with Papaparse or do I have to do it through code?
Thanks.

I can access elements such as id , title or logo because they are not arrays.
How can I loop through the data inside the array since there is an array in the category in yield?
var data = this.database.filter((item) => item.type == searchType)
var data = this.database.filter((item) => item.category == searchCategory)
It's okay because my type value doesn't have an array.
But when I enter my category value, it only gets the first index[0]. It does not look at other indexes.
in summary,
item.category[0] , item.category[1] , item.category[2]...........
How can I get index browsing like
if your data looks like this :
let data ={
"age" : "18",
"altKategoriler" : [ "Dramalar" ],
"category" : [ "Aksiyon", "Heyecanlı", "Gerilim" ],
"id" : 5240718100,
"img" : "https://i.ibb.co/k8wx5C8/AAAABW9-ZJQOg-MRljz-Zwe30-JZw-Hf4vq-ERHq6-HMva5-ODHln-Ci-OEV6ir-Rcjt88tcnm-QGQCKpr-K9h-Oll-Ln-Sbb-EI.jpg",

"oyuncuKadrosu" : [ "Diego Luna", "Michael Pena", "Scoot McNairy", "Tenoch Huerta", "Joaquin Cosio" ],
"senarist" : [ "Doug Miro" ],
"time" : "3 Sezon",
"title" : "Narcos: Mexico",

"yonetmen" : [ "Carlo Bernard", "Chris Brancato" ]
}
and if we have array of data you can do something like this :
myArray.filter(item=>item.category.indexOf(searchCategory)>=0)
but if you want to explore in object rather than array you can do this :
data.category.indexOf(searchCategory)>=0
You could make this a bit generic, by testing whether the targeted field is an array, using Array.isArray, and then call a filter on each element, and see if any is positive (using .some()). The filter can be function that is provided, so that it can perform a simple match, or apply a regular expression, or anything else.
Instead of testing with Array.isArray you could skip that step and check whether the value has a .some() method. If so, calling it will give the desired outcome, and otherwise (using the .? and ?? operators), the filter should be applied to the value as a whole:
Here is how that looks:
function applyFilter(data, field, filter) {
return data.filter(item => item[field]?.some(filter) ?? filter(item));
}
// Example use:
var data = [{
"category" : [ "Action", "Thriller", "Horror"],
"type" : "Series",
}, {
"category" : [ "Historical", "Romance" ],
"type" : "Theatre",
}];
// Find entries that have a category that looks like "roman*":
var result = applyFilter(data, "category", value => /^roman.*/i.test(value));
console.log(result);
If you are running on an older version of JavaScript, and don't have support for .? or ??, then use:
return data.filter(item => Array.isArray(item[field])
? item[field].some(filter)
: filter(item));
I have a json file named a1.json->(It has the following structure)
{ "Key1" :
[ {
"Key11" : "Value11" ,
"Key12" : "Value12"
},
{
"Key21" : "Value21" ,
"Key22" : "Value22"
}
]
}
I am iterating through a data file which has certain values. If the values match i will have to add an extra key to that particular dictionary only. For example-
{ "Key1" :
[ {
"a" : "A1" ,
"b" : "B1"
},
{
"a" : "A2" ,
"b" : "B2"
}
]
}
I want to add a key value pair in that list whose key value "a" is "A1". So the final result will look something like this-
{ "Key1" :
[ {
"a" : "A1" ,
"b" : "B1" ,
"New_Key_Array" :
[
{
"Found" : "yes",
"Correctness" : "true"
}
]
},
{
"a" : "A2" ,
"b" : "B2"
}
]
}
How do I go about this. I am a bit new to JSON formatting and still learning how to edit existing JSON files?
You can use JSON.parse() to parse your json file/string into a JavaScript object. In your example:
let j = JSON.parse('{ "Key1" :[ { "a" : "A1" , "b" : "B1"},{"a" : "A2" , "b" : "B2"}]}');
To add a new key to your object, it's possible with native JavaScript code, if that's what you want:
j.Key1[0]["New_Key_Array"] = [ { Found: "yes", Correctness: "true" } ];
To convert back into json formatted string, you can use the JSON.stringify() function.
I am providing a code snippet for your problem:
let j = JSON.parse('{ "Key1" :[ { "a" : "A1" , "b" : "B1"},{"a" : "A2" , "b" : "B2"}]}');
console.log("JSON at the beginning:\n", j);
j.Key1.forEach((element, index) =>{
if(element.a === "A1"){
//Here I have to edit the JSON obj
j.Key1[index]["New_Key_Array"] = [ { Found: "yes", Correctness: "true" } ];
}
});
console.log("JSON edited:\n ",j);
let objString =JSON.stringify(j);
I'm trying to match mongodb object id with if condition:
if (reply[i].data[j].ref == item._id) console.log('match!!!')
The sample of reply & item:
// REPLY
[{
"_id":10,
"data": [
{
"_id":"57f485203858fe43b464ae52",
"type":"product",
"ref":"57f485473858fe43b464ae56",
"name":"KARUNG",
"direction":"in",
"supplier":null,
"information":"PENYESUAIAN JUMLAH",
"qty":200,
"manifest":null,
"timestamp":"2016-10-05T04:44:16.354Z",
"saldo":1200
}
]
}]
// ITEM
{
"_id" : "57f485473858fe43b464ae56",
"name" : "BERAS KC",
"unit" : "SAK",
"qty" : 213,
"weight" : 10
}
I was also trying to convert both to ObjectId using mongojs.ObjectId, but it doesn't work.

I want to limit my query's result to a set of fields. This is one of my documents:
{
"_id" : "WA9QRuiWtGsr4amtT",
"status" : 3,
"data" : [
{
"name" : "0",
"value" : "Text ..."
},
{
"name" : "1",
"value" : "12345678"
},
{
"name" : "2",
"value" : "Text"
},
{
"name" : "4",
"value" : "2"
},
{
"name" : "8",
"value" : true
},
{
"name" : "26",
"value" : true
},
],
"userId" : "7ouEumtudgC2HX4fF",
"updatedAt" : NumberLong(1415903962863)
}
I want to limit the output to the status field as well a the first and third data document.
This is what I tried:
Meteor.publish('cases', function () {
var fields = {
currentStatus: 1,
'data.0': 1,
'data.2': 1
};
return Cases.find({}, { fields: fields });
});
Sadly it doesn't work. Something else I found is $elemMatch but it only returns the first element:
data: {
$elemMatch: {
name: {
$in: ['0', '2']
}
}
},
How can I limit the output to these fields?
To display status and data(unlimited) fields try
cases.find({}, {"status":1, "data":1})
This is simple query, to limit "data" output you will need to work harder :)
Get 1 element by data.name (not by position):
cases.find({}, {status:1, "data": {$elemMatch:{name:"0"}}})
Get 1 element by data.name, but from a list of values:
cases.find({}, {status:1, "data": {$elemMatch:{name:{$in:["0", "1"]}}}})
To get close to your question, you may try redact. That is new in Mongodb 2.6.
Or play with $unwind and .aggregate() in previous editions.
So far, I do not see a way to return array elements based on a position.
This line in my JS file:
RedQueryBuilderFactory.create(config,
'SELECT "x0"."title", "x0"."priority" FROM "ticket" "x0" WHERE ("x0"."status" = (?))',
[]
);
works fine witih an empty array as the 3rd parameter. This parameter is supposed to be an array of strings according to the documentation and any sample code I can find. When I pass a string in the array it fails:
RedQueryBuilderFactory.create(config,
'SELECT "x0"."title", "x0"."priority" FROM "ticket" "x0" WHERE ("x0"."status" = (?))',
['in_process']
);
I get java.lang.ClassCastException in the Safari console. Here's the related part of the config if it's relevant:
var config = {
meta : {
tables : [ {
"name" : "ticket",
"label" : "Ticket",
"columns" : [ {
"name" : "title",
"label" : "Title",
"type" : "STRING",
"size" : 255
}, {
"name" : "priority",
"label" : "Priority",
"type" : "REF"
} ],
fks : []
} ],
types : [ {
"name" : "REF",
"editor" : "SELECT",
"operators" : [ {
"name" : "IN",
"label" : "any of",
"cardinality" : "MULTI"
}]
} ]
}
};
Looks like this is a bug in passing in parameter values. Internally it is expecting a collection but this is not happening.
Best if you raise a https://github.com/salk31/RedQueryBuilder bug report here?
NB Should be "IN" not "="
