Is there a possible way to write my ObjectBox-Box Data to a file, after parsing it to code.
I tried to marshal it with json but it keeps giving me
{"ObjectBox":{}}
``
I just found out, that the library saves the data.
Whenever you just call a new builder, it does not refresh the database, but it calls the current one.

I am trying to upload JSON files to BigQuery. The JSON files are outputs from the Lighthouse auditing tool. I have made some changes them in Python to make field names acceptable for BigQuery and converted the format into newline JSON.
I am now testing this process and I have found that while for many web pages the upload runs without issue, BigQuery is rejecting some of the JSON files. The rejected JSONs always seem to be from the same website, for example, many of the audit JSONs from Topshop have failed on upload (the manipulations in Python run without issue). What I am confused by is that I can see no difference in the formatting/structure of the JSONs which succeed and fail.
I have included some examples here of the JSON files: https://drive.google.com/open?id=1x66PoDeQGfOCTEj4l3VqMIjjhdrjqs9w
The error I get from BigQuery when a JSON fails to load is this:
Error while reading table: build_test_2f38f439_7e9a_4206_ada6_ac393e55b8ec4_source, error message: Failed to parse JSON: No active field found.; ParsedString returned false; Could not parse value; Could not parse value; Could not parse value; Could not parse value; Could not parse value; Could not parse value; Parser terminated before end of string
I have also attempted to upload the failed JSONs to a new table through the interface using the autodetect feature (in an attempt to discover whether the Schema was at fault) and these uploads fail too, with the same error.
This makes me think the JSON files must be wrong, but I have copied them into several different JSON validators which all accept them as one row of valid JSON.
Any help understanding this issue would be much appreciated, thank you!
When you load JSON files to BigQuery, it's good to remember that there are some limitations associated to this format. You can find them here. Even though your files might be valid JSON files, some of them may not comply with BigQuery limitations, so I would recommend you to double check if they are actually correct for BigQuery.
I hope that helps.
I eventually found the error here through a long trial and error process where I uploaded first the first-half and then the second-half of the JSON file to BigQuery. The second-half failed so I split that in half again to see which half the error occurred in. This continued until I found the line.
At a deep level of nesting there was a situation where one field was always a list of strings, but when there were no values associated with the field it appeared as an empty string (rather than an empty list). This inconsistency was causing the error. The trial and error process was long but given the vague error message and that the JSON was thousands of lines long, this seemed like the most efficient way to get there.
i have this JSON array stored in my local variable:
let bigJsonArray = JSON(response)
my question is if there is any possibility to store this "bigJsonArray" in a global variable/session/cookie/config so i can access it in every view of my app ?
Anybody knows how to process this and could help me?
Greetings and thanks!
What you can do is to define bigJsonArray as a global variable just by defining it outside of any class and the Swift compiler will understand it as a global variable and you can access it from anywhere in your code.
for example:
import UIKit
var bigJsonArray = JSON(response)
class a {
var x = 0
}
that's of curse will not save the data if you killed the app, but from what I understand from your question you just need to be able to access it from all the app without resending a request to the server.
If you want to save the JSON data permanently, you just store the data that you received as a file, and the next time you need it, you read it from the file and parse it (there's actually a method for that) instead of downloading and parsing the data. Much easier than trying to store the parsed data.
If this is data that can be downloaded again, read the appropriate documentation to make sure the file isn't backed up, and is stored in a cache directory where the OS can remove it if space is tight.
I am loading data from a mongodb collection to a mysql table through Kettle transformation.
First I extract them using MongodbInput and then I use json input step.
But since json input step has very low performance, I wanted to replace it with a
javacript script.
I am a beginner in Javascript and even though i tried somethings, the kettle javascript script is not recognizing any keywords.
can anyone give me sample code to convert Json data to different columns using javascript?
To solve your problem you need to see three aspects:
Reading from MongoDB
Reading from JSON
Reading from (probably) String
Reading from MongoDB Except if you changed the interface, MongoDB returns not JSON but BSON files (~binary JSON). You need to see the MongoDB documentation about reading and writing BSON: probably something like BSON.to() and BSON.from() but I don't know it by heart.
Reading from JSON Once you have your BSON in JSON format, you can read it using JSON.stringify() which returns a String.
Reading from (probably) String If you want to use the capabilities of JSON (why else would you use JSON?), you also want to use JSON.parse() which returns a JSON object.
My experience is that to send a JSON object from one step to the other, using a String is not a bad idea, i.e. at the end of a JavaScript step, you write your JSON object to a String and at the beginning of the next JavaScript step (can be further down the stream) you parse it back to JSON to work with it.
I hope this answers your question.
PS: writing JavaScript steps requires you to learn JavaScript. You don't have to be a master, but the basics are required. There is no way around it.
you could use the json input step to get the values of this json and put in common rows
Hopefully this is simple issues, where I have obviously missed something in the RTFM.
I have an application I am integrating Fine Uploader, and I have it working now in terms of uploading files to the server. The only issue is that I need to take some action on the client side each time the user successfully uploads a file.
In short I would like to have a hidden input field with a comma separated list of files which have been successfully been uploaded.
In my JSON response from my server side implementation. I am of course including "success: true". In addition I have a entry called "file: /path/to/savedUpload.file".
So when an upload is performed successfully, I just need to know how to call my own method with the json response passed in so I can take care of managing the hidden input element.
Thanks in advance for any assistance!

I have a PHP file that is queried for information, and it passes a couple of variables back. One variable contains a JSON string with a variable in the object called message, which comes escaped to prevent it from causing issues if the message has an ampersand, single quote, etc in it.
&data={"message":"star%27s"}
Obviously the data sent is more complicated, this is just an example. After I take the data passed back by the PHP file and use URLVariables to decode it and access the "data" variable, it ends up looking like:
{"message":"star's"}
At this point I can't parse the JSON string, it will throw an error because of the single quote. Encoding it wouldn't work, it would encode more than just everything after the colon.
Is there a way to keep it from converting it? I was thinking I could manually parse the PHP returned string, but it seems unnecessary and I don't want risk running into issues later on because of it. I looked at the AS3 API and I couldn't find anything documenting this or how to disable it.
Any ideas or suggestions?
You try with
Actionscript API escape() and unescape() see for more details Escape and unescape
Also look at JSON.parse and JSON.stringify working-with-native-json-in-flash-player-11
JSON decode in actionscript see decode-json
