printing the array under array in json file? - javascript

//I write a code of a json file in visual studio code....
let coll={
"collName" : "pu_vendor",
"collDesc" : "Vendor Master",
"formName" : "syscollection",
"formType" : "CRUD",
"docLevel" : [
{
"level" : 0,
"levelName" : "root",
"levelDesc" : "Vendor Description",
"parent" : "",
"comments" : "",
"fields" : [
{
"fieldName" : "vndrId",
"fieldDesc" : "Vendor ID",
"dataType" : "S",
"size" : 5,
"comments" : ""
}
]
}
]
}
i want to print all values with all keys type of key:value pattern....So i easily print with console.log
console.log(coll);
it shows truely all value by key:value pattern also but when it is comes on the next "fields" key, it prints only the type of this key i.e [Array], it do not show the keys and values of this key

MongoDB - Query nested objects in nested array

I'm kindly requesting your help for this query that I need to do and I'm not very proficient yet in MongoDB. My data structure looks like this:
db.getCollection('EventDateValidation').find({}):
/* 1 */
{
"_id" : ObjectId("5b7b2e3ae5e2100007717d81"),

}
}
]
}
From this collection, I need to find the documents that have an "auditedDate" in the "deadlineDate". In this example, I would find the documents 1 and 3. Please help me as I'm stuck on this one.
I have tried
db.getCollection('EventDateValidation').find({"validationStepData.deadlineDate.auditedDate":{$exists:true}})
But doesn't seem to work. Help please!
Just for clearing things up: the query in the question works well. I chatted with #Gabriel, and the problem was that Robomongo added hidden non-printable unicode characters to the query.
All in all, for any interested nomads, here are few ways to query an array of objects:
1) Implicit $elemMatch / simple dot notation on an array:
db.getCollection('EventDateValidation').find({"validationStepData.deadlineDate.auditedDate": {$exists:true}})
2) Explicit $elemMatch (we can have multiple query criteria):
db.getCollection('EventDateValidation').find({"validationStepData": { $elemMatch: {"deadlineDate.auditedDate" : {$exists:true} }}})
3) Array dot notation with an index position (when we know the exact position of an element inside an array):
db.getCollection('EventDateValidation').find({"validationStepData.2.deadlineDate.auditedDate": {$exists:true}})
Dot notation wouldn't work since you have an array of objects within validationStepData. You could use $elemMatch to apply your query conditions to the array elements that match your expression.
db.getCollection('EventDateValidation').find({"validationStepData" : { $elemMatch: {"deadlineDate.auditedDate" : {$exists:true} }}})

Firebase query taking forever

My firebase data looks like this...
In JSON down below...
I've been trying to use what I've found in their docs to query the db so that I end up with of all the terms and their keys. How do I query just the term property and key for every node under vocab? I'm using this to populate an autosuggest. Also, the 0 and 1 under the vocab node are keys... they showed up that way when I imported the data as a JSON file. Any new vocab goes in with unique long key values though.
I've tried both .on() and .equalTo()... But I have had no luck whatsoever. It always seems to be grabbing everything in the entire vocab node of the database and taking on the order of 7 whole seconds to do it each time. Here is an example of one of my attempts where I try to put just the terms into an array...
let termList = [];
const termsRef = firebase.database().ref('vocab/');
termsRef.on('child_added', snap => termList.push(snap.val().term));
This doesn't even get the keys (which I need) and it still takes around 7 seconds to do it. I've seen videos where people do things like this in one line and it goes quick... not my luck. Any help would be much appreciated.
As requested here is a JSON sample of one of the database nodes... there are over 400 like this... the relevant property is term... all the way at the bottom. I need an array of terms and firebase database keys. How do I get them with a query?

I need to import data from this type of format into my mysql database.
I can't finalize and nail down the approach to do this
I tried to get the file content into a php file and then convert them into a array string but i get a null result.
$jsondata = file_get_contents('trial_data.js');
$data = json_decode($jsondata, true);
var_dump($data);
The second approach I think i can take is load the data in jquery file and send it using AJAX to a php file which adds it to the database.
Which approach do you think i should take and how to go about it.
Plus i need to figure out the ID from the first index array, so that I can get the ID from the me and org object for which i need to get the rest of the information
Since your data is not a valid JSON, you can use a regex to parse it, like this:
$file_content = file_get_contents('trial_data.js');
preg_match_all("/(\w+)\[\"([^\]]*)\"\]\s*\=\s*\{([^\}]*)\}/", $file_content, $matches);
foreach ($matches[1] as $key => $value) {
$data[$value][$matches[2][$key]] = json_decode('{'.$matches[3][$key].'}');
}
print_r($data);
//For example:
echo $data['users']['524bd089-2a7b-4a71-ba23-16354d6351ae']->pictureName;
//Output: 66s2c.jpg

updating mongodb using $push operator in angular-meteor

I am trying to push arrays from one collection to another.
this is the code I used in my server js
updateSettings: function(generalValue) {
let userId = Meteor.userId();
let settingsDetails = GeneralSettings.findOne({
"_id": generalValue
});
Meteor.users.update({
_id: userId
}, {
$push: {
"settings._id": generalValue,
"settings.name": settingsDetails.name,
"settings.description": settingsDetails.description,
"settings.tag": settingsDetails.tag,
"settings.type": settingsDetails.type,
"settings.status": settingsDetails.status
}
})
}
updateSettings is the meteor method. GeneralSettings is the first collection and user is the second collection. I want to push arrays from GeneralSettings to users collection. While I try this the result i got is like
"settings" : {
"_id" : [
"GdfaHPoT5FXW78aw5",
"GdfaHPoT5FXW78awi"
],
"name" : [
"URL",
"TEXT"
],
"description" : [
"https://docs.mongodb.org/manual/reference/method/db.collection.update/",
"this is a random text"
],
"tag" : [
"This is a demo of an Url selected",
"demo for random text"
],
"type" : [
"url",
"text"
],
"status" : [
false,
false
]
}
But the output I want is
"settings" : {
"_id" : "GdfaHPoT5FXW78aw5",
"name" : "URL",
"description" :
"https://docs.mongodb.org/manual/reference/method/db.collection.update/",
"tag" :"This is a demo of an Url selected",
"type" : "url",
"status" : false
},
What changes to be made in my server.js inorder to get this output
This is one case where you "do not want" to use "dot notation". The $push operator expects and Object or is basically going to add the "right side" to the array named in the "left side key":
// Make your life easy and just update this object
settingDetails._id = generalValue;
// Then you are just "pushing" the whole thing into the "settings" array
Meteor.users.update(
{ _id: userId },
{ "$push": { "settings": settingDetails } }
)
When you used "dot notation" on each item, then that is asking to create "arrays" for "each" of the individual "keys" provided. So it's just "one" array key, and the object to add as the argument.

Unable to print BSON object from javascript

My mongoDB collection looks like this :
{
"_id" : ObjectId("5070310e0f3350482b00011d"),
"emails" : [
{
"_id" : ObjectId("5070310e0f3350482b000120"),
"_type" : "Email",
"name" : "work",
"email" : "peter.loescher#siemens.com",
"current" : true
}
]
}
and this is the .js code i use to print the contents :
c = db.contacts.findOne( { "emails.email" : { $ne : null } }, { "emails" : 1 } )
print(c._id.toString() + " " + c.emails[0]);
when I try to run this javascript file, it is just displaying the id but not the email array.
output:
5070310e0f3350482b00011d [object bson_object]
but when I try c.emails[0].email is is giving proper result. i.e. peter.loescher#siemens.com
All I need is I want to display the whole emails embedded object.
i.e.
"emails" : [
{
"_id" : ObjectId("5070310e0f3350482b000120"),
"_type" : "Email",
"name" : "work",
"email" : "peter.loescher#siemens.com",
"current" : true
}
]
Where I am going wrong?. Any help would be appreciated.
You need printjson to output a nicely formatted JSON:
printjson(c.emails[0]);
Here it is the documentation.
