I am implementing a restful service where I am getting the pdf names and their ids from the database in the JSON fromat. Which one of the both the convenient JSON resful service response?
First Option:
{
"results": {
"documentNames": [
"test.pdf",
"ireport-ultimate-guide.pdf",
"sending report.pdf",
"Motor Hour.pdf"
],
"documentds": [
21116,
21117,
21118,
21119
]
}
}
Second Option:
{
"results": {
"21116": "test.pdf",
"21117": "ireport-ultimate-guide.pdf",
"21118": "sending report.pdf",
"21119": "Motor Hour.pdf"
}
}
I would use this "third option": The result is a list of object.
{
"result": [{
"id": "21116",
"filename": "test.pdf"
},
{
"id": "21117",
"filename": "ireport-ultimate-guide.pdf"
},
{
"id": "21118",
"filename": "sending report.pdf"
},
{
"id": "21119",
"filename": "Motor Hour.pdf"
}
]
}
because it better models the object structure.
I would create an entity for each document that contains both name and I'd.
[
{"name": "doc_1", "id": 123},
{"name": "doc_2", "id": 456}
]

I have a json file with this structure
"user_data": {
"0": {
"user_name": "LinkedIn",
"type": "textfile"
"id": "543211",
"all_tickets": [
"56788",
"43224",
"56788"
]
};
"1": {
"user_name": "stackoverflow",
"type": "textfile"
"id": "123456",
"all_tickets": [
"98134",
"76372",
"44522"
]
}
}
}
Whenever user inputs the same data, I want to check against the existing one in the json file and if it matches, I want to return the index. How can I get it?
For example, if a user inputs the same keys and values of :
"user_name": "LinkedIn",
"type": "textfile"
"id": "543211",
"all_tickets": [
"56788",
"43224",
"56788"
]
The output should be 0(since that is the index)
Can someone help me to access myapp from below json using python, please ?
{
"Data": {
"Name": "myname",
"AccountName": "test",
"classic": [
{
"cName": "mycname",
"tags": ["tag1", "tag2"],
"Version": "1.14.10",
"app": "myapp"
}
]
}
}
Use json.load for reading a file or json.loads for a string.
data_dict = json.loads(your_data)
print(data_dict["Data"]["classic"][0]["app"])
Use json loads to parse a json string and json dumps for stringifying the json to a json string
Here in your case you will need json loads
input = {
"Data": {
"Name": "myname",
"AccountName": "test",
"classic": [
{
"cName": "mycname",
"tags": ["tag1", "tag2"],
"Version": "1.14.10",
"app": "myapp"
}
]
}
}
parsed_input = json.loads(input)
output = parsed_input["Data"]["classic"][0]["app"]
print(output)
You can use json library for the same.
input_json= {
"Data": {
"Name": "myname",
"AccountName": "test",
"classic": [
{
"cName": "mycname",
"tags": ["tag1", "tag2"],
"Version": "1.14.10",
"app": "myapp"
}
]
}
}
data = json.loads(input_json)
result=data["Data"]["classic"][0]["app"])
I'm trying to get my mocked JSON data via GraphQL in Gatsby. The response shows the correct data, but also two null objects as well. Why is it happening?
I'm using the gatsby-transformer.json plugin to query my data and gatsby-source-filesystem to point the transformer to my json files.
categories.json
the mock file I'm trying to get to work :)
{
"categories": [
{
"title": "DEZERTY",
"path": "/dezerty",
"categoryItems": [
{
"categoryName": "CUKRIKY",
"image": "../../../../static/img/dessertcategories/cukriky.jpg"
},
{
"categoryName": "NAHODNE",
"image": "../../../../static/img/dessertcategories/nahodne.jpg"
},
]
},
{
"title": "CANDY BAR",
"path": "/candy-bar",
"categoryItems": [
{
"categoryName": "CHEESECAKY",
"image": "../../../../static/img/dessertcategories/cheesecaky.jpg"
},
{
"categoryName": "BEZLEPKOVÉ TORTY",
"image": "../../../../static/img/dessertcategories/bezlepkove-torty.jpg"
},
]
}
]
}
GraphQL query in GraphiQL
query Collections {
allMockJson {
edges {
node {
categories {
categoryItems {
categoryName
image
}
title
path
}
}
}
}
}
And the response GraphiQL gives me
{
"data": {
"allMockJson": {
"edges": [
{
"node": {
"categories": null
}
},
{
"node": {
"categories": null
}
},
{
"node": {
"categories": [
{
"categoryItems": [
{
"categoryName": "CHEESECAKY",
"image": "../../../../static/img/dessertcategories/cheesecaky.jpg"
},
{
"categoryName": "BEZLEPKOVÉ TORTY",
"image": "../../../../static/img/dessertcategories/bezlepkove-torty.jpg"
}
],
"title": "DEZERTY",
"path": "/dezerty"
},
{
"categoryItems": [
{
"categoryName": "CUKRIKY",
"image": "../../../../static/img/dessertcategories/CUKRIKY.jpg"
},
{
"categoryName": "NAHODNE",
"image": "../../../../static/img/dessertcategories/NAHODNE.jpg"
}
],
"title": "CANDY BAR",
"path": "/candy-bar"
}
]
}
}
]
}
}
}
I expected only to get the DEZERTY and CANDY BAR sections. Why are there null categories and how do I fix it?
Thanks in advance
Your JSON contains syntax errors in the objects DEZERTY and CANDY BAR. It silently fails without telling you. Try this json linter.
Error: Parse error on line 12: },
Error: Parse error on line 25: },
Try again. Your query should work now.
You should look into an IDE that highlights these types of errors and saves you time and frustration.
I'm prototyping a web service to convert data using Design Automation API in Autodesk Forge.
My approach is to invoke an activity that executes a script to import a target data file (such as STEP, IGES format).
As an example, I created an activity to convert a STEP file to DWG as follows:
{
"HostApplication": "",
"RequiredEngineVersion": "22.0",
"Parameters": {
"InputParameters": [{
"Name": "Source",
"LocalFileName": "input.stp"
}, {
"Name": "HostDwg",
"LocalFileName": "$(HostDwg)"
}],
"OutputParameters": [{
"Name": "Result",
"LocalFileName": "output.dwg"
}]
},
"Instruction": {
"CommandLineParameters": null,
"Script": "import\ninput.stp\nsaveas\n\noutput.dwg\n"
},
"Version": 1,
"Id": "Step2Dwg"
}
The workitem to invoke this activity was executed without errors, but the output file (output.dwg) had nothing imported from the input file (input.stp).
Perhaps this is because some fields (e.g., AllowedChildProcess) were missing in the definition of the activity "Step2Dwg", but I do not know how to fix it.
My questions are:
How to fix the definition of the activity "Step2Dwg" to convert data successfully?
Is there any other approach to create an activity to convert data successfully?
You can use the Activity “Translate-STEP2DWG". It takes a .stp file as input and generate result.dwg as output. This is a public activity that anybody can send workitems against to it.
The activity is defined like this:
{
"Id": "Translate-STEP2DWG",
"AppPackages": [],
"HostApplication": "AcTranslators.exe",
"RequiredEngineVersion": "22.0",
"Parameters": {
"InputParameters": [
{
"Name": "HostDwg",
"LocalFileName": "source.stp"
}
],
"OutputParameters": [
{
"Name": "Result",
"LocalFileName": "result.dwg"
}
]
},
"Instruction": {
"CommandLineParameters": "-i source.stp -o result.dwg",
"Script": ""
},
"AllowedChildProcesses": [
],
"IsPublic": true,
"Version": 1,
"Description": ""
}
Here is a sample workitem request body:
{
"ActivityId": "Translate-STEP2DWG",
"Arguments": {
"InputArguments": [
{
"Resource": "https://s3.amazonaws.com/AutoCAD-Core-Engine-Services/TestDwg/3DStep.stp",
"Name": "HostDwg"
}
],
"OutputArguments": [
{
"Name": "Result",
"HttpVerb": "POST"
}
]
}
}
My object is
{
"name":"Testing",
"id": "hcig_3fe7cb00-e936-11e6-af69-a748c8cc89ad",
"belongsTo": {
"id": "69616d26-c3bb-405c-8c84-c51c091524b2",
"name": "test"
},
"locatedAt": {
"id": "49616d26-c3bb-405c-8c84-c51c091524b2",
"name":"Test"
} }
I want to merge one more object like
"obj":[{
"a": 123
}}
With the help of JSON_MERGE in mysql document store i am able to add object.
But it looks likes
{
"name":"Tester",
"id": "hcig_3fe7cb00-e936-11e6-af69-a748c8cc89ad",
"belongsTo": {
"id": "69616d26-c3bb-405c-8c84-c51c091524b2",
"name": "test"
},
"locatedAt": {
"id": "49616d26-c3bb-405c-8c84-c51c091524b2",
"name":"Test"
},{
"obj":[{
"a": 123
}]
}}
I want my object to be as
{
"name": "Tester",
"id": "hcig_3fe7cb00-e936-11e6-af69-a748c8cc89ad",
"belongsTo": {
"id": "69616d26-c3bb-405c-8c84-c51c091524b2",
"name": "test"
},
"locatedAt": {
"id": "49616d26-c3bb-405c-8c84-c51c091524b2",
"name": "Test"
},
"obj": [{
"a": 123
}]}
Any idea on how to add object as above manner using JSON Functions in mysql ??
Use lodash for a recursive deep copy - https://lodash.com/
lodash.merge(targetObj, sourceObj);
Or if you have programmatic access:
targetObj.obj = sourceObj;
