I have some Dart code that need replace all the keyword to full string based on a json list. I now using the most easy method to replaceAll string one by one but it seem not ok to work on a very long json, how do write a function take json and replace based on the key label field?
String replaceString(String str) {
str = str.replaceAll('key_a', 'created');
str = str.replaceAll('key_b', 'replied');
str = str.replaceAll('key_c', 'assigned');
str = str.replaceAll('key_d', 'unassigned');
str = str.replaceAll('key_e', 'terminated');
return str;
}
json get from api
{
"key_a": {
"label": "created",
"type": ""
},
"key_b": {
"label": "replied",
"type": ""
},
"key_c": {
"label": "assigned",
"type": ""
}
..... and many more
}

I need to deserialize ( and later on serialize ) a piece of data that has this type of a structure :
{
"type": "TypeApplication",
"val": {
"con": {
"type": "TypeConstructor",
"val": [
"Builtin",
"Record"
]
},
"arg": {
"type": "RowCons",
"val": {
"label": "953e3dd6-826e-1985-cb99-fd4ed4da754e",
"type": {
"type": "TypeApplication",
"val": {
"con": {
"type": "TypeConstructor",
"val": [
"Builtin",
"List"
]
},
"arg": {
"type": "Element",
"meta": {
"multiLine": true
}
}
},
"system": {
"label": "nullam-senectus-port - Text",
"isBindable": true,
"defaultValue": [
{
"id": "4a05486f-f24d-45f8-ae13-ab05f824d74d",
"type": "String",
"pluginType": "Basic",
"data": {
"value": "Nullam senectus porttitor in eget. Eget rutrum leo interdum."
},
"children": [],
"text": true
}
],
"isUnlinked": false,
"isDefault": false
}
},
"tail": {
"type": "RowCons",
"val": {
"label": "94f603df-d585-b45a-4252-9ec77cf5b13c",
"type": {
"type": "TypeApplication",
"val": {
"con": {
"type": "TypeConstructor",
"val": [
"Builtin",
"List"
]
},
"arg": {
"type": "Element",
"meta": {
"multiLine": true
}
}
},
"system": {
"label": "best-services - Text",
"isBindable": true,
"defaultValue": [
{
"id": "6265ca45-3f69-4844-97e2-c05bbfb9fee5",
"type": "String",
"pluginType": "Basic",
"data": {
"value": "Best Services"
},
"children": [],
"text": true
}
]
}
},
"tail": {
"type": "RowEmpty"
}
}
}
}
}
}
}
I do not know what this data exactly is, but I know this is trying to represent a function/element that takes in values and defaults for those values as parameters/properties.
I want to deserialize it using serde and consequently serialize it too.
I have so far been able to write something that sort of works but not really :
#[skip_serializing_none]
#[derive(Deserialize, Serialize, Debug, Clone)]
#[serde(tag = "type", content = "val")]
pub enum WebflowPropDataType {
TypeApplication {
con: Box<WebflowPropDataType>, // Normally Passes the Type Constructor
arg: Box<WebflowPropDataType>, // Normally Passes the Row Constructor
},
TypeConstructor(Vec<String>), // Stores Value of TypeConstructor
RowCons {
label: String, // Stores the label of the Row
#[serde(rename = "type")]
row_con_type: Box<WebflowPropDataType>, // Stores the type of the Row
tail: Box<WebflowPropDataType>,
},
RowEmpty, // For Ending the recursive usage of rowConstructor
}
#[skip_serializing_none]
#[derive(Deserialize, Serialize, Debug, Clone)]
pub struct WebflowRowConDataType {
#[serde(rename = "type")]
val_type: String, // TypeApplication
val: Box<WebflowPropDataType>,
}
This works for a structure like this :
{
"type": "TypeApplication",
"val":{
"con": {
"type": "TypeConstructor",
"val": []
},
"arg": {
"type": "RowEmpty"
}
}
}
but would fail if I try to work with initial example. I know this may be due to the lack of a proper arg type or maybe even the TypeApplication Enum hand is malformed.
I do see that a adjancent typing solution would be enough for most of the times but there are cases as seen in the example structure that there is a third value called system and I am unable to determine what type of approach would help me achieve this type of outcome.
How should I approach this problem in order to generate this type of code.
I am not asking anyone to write me a solution but to give me suggestion as to what my approach should be? Whether you'd know what type of data this is/how to generated this , or even if there are some other library I should look into to manipulate this type of data or maybe look at other approaches.
PS : - My end goal is to be able to generate / serialize this type of JSON code from already contained knowledge of properties and default values of a function/object.
Here are my recommendations:
Use just #[serde(tag = "type")] instead of #[serde(tag = "type", content = "val")]. You will have to handle val manually (extracting the current enum members into separate structs), but this allows you to also handle TypeApplication.system and Element.meta.
This also has the small benefit of reducing the amount of Boxes involved.
Consider whether all of the different cases in WebflowPropDataType can actually occur everywhere it's used. If not (maybe Element can only happen under TypeApplication.val.arg), then you may want to split the enum into multiple so that this is reflected in the type system.
Example for #1:
use serde::{Serialize, Deserialize};
#[derive(Deserialize, Serialize, Debug, Clone)]
pub struct TypeApplicationVal {
con: WebflowPropDataType, // Normally Passes the Type Constructor
arg: WebflowPropDataType, // Normally Passes the Row Constructor
}
// #[skip_serializing_none]
#[derive(Deserialize, Serialize, Debug, Clone)]
pub struct TypeApplicationSystem {
label: String,
#[serde(rename = "isBindable")]
is_bindable: bool,
// TODO: defaultValue
#[serde(rename = "isUnlinked")]
#[serde(skip_serializing_if = "Option::is_none")]
is_unlinked: Option<bool>,
#[serde(rename = "isDefault")]
#[serde(skip_serializing_if = "Option::is_none")]
is_default: Option<bool>,
}
#[derive(Deserialize, Serialize, Debug, Clone)]
pub struct RowConsVal {
label: String, // Stores the label of the Row
#[serde(rename = "type")]
typ: WebflowPropDataType, // Stores the type of the Row
tail: WebflowPropDataType,
}
#[derive(Deserialize, Serialize, Debug, Clone)]
pub struct ElementMeta {
#[serde(rename = "multiLine")]
multi_line: bool,
}
#[derive(Deserialize, Serialize, Debug, Clone)]
#[serde(tag = "type")]
pub enum WebflowPropDataType {
TypeApplication {
val: Box<TypeApplicationVal>,
#[serde(skip_serializing_if = "Option::is_none")]
system: Option<TypeApplicationSystem>,
},
TypeConstructor {
val: Vec<String> // Stores Value of TypeConstructor
},
RowCons {
val: Box<RowConsVal>,
},
Element {
meta: ElementMeta,
},
RowEmpty, // For Ending the recursive usage of rowConstructor
}

I started exploring Google Docs API in Python. It does pretty much everything I want it to do except for one thing.
I can replace the text of a document but I can't change the value of the hyperlinks.
Meaning if a link looks like this : a link, I can change the value of the text a link but not the target URL.
I've been going through the documentation but I can't find anything about it. Could it be a missing feature or am I missing the way to do that?
You can modify the hyperlink using UpdateTextStyleRequest of the batchupdate method in Google Docs API. At this time, please set the property of Link of TextStyle.
Endpoint
POST https://docs.googleapis.com/v1/documents/{file ID}:batchUpdate
Request body:
{
"requests": [
{
"updateTextStyle": {
"textStyle": {
"link": {
"url": "https://sampleUrl" # Please set the modified URL here.
}
},
"range": {
"startIndex": 1,
"endIndex": 2
},
"fields": "link"
}
}
]
}
Note:
From your question, I could understand that you have already used Google Docs API and you can modify the text of the link text. I think that you can modify the link using above request body and the script you have.
References:
UpdateTextStyleRequest
TextStyle
Link
If this was not useful for your situation, I apologize.
Edit:
You want to retrieve the text with the hyperlink.
From your reply comment, I could understand like above. When my understanding is correct, you can retrieve it using documents.get method. In this case, when fields is used, the response become to easily read.
Endpoint:
GET https://docs.googleapis.com/v1/documents/{file ID}?fields=body(content(paragraph(elements(endIndex%2CstartIndex%2CtextRun(content%2CtextStyle%2Flink%2Furl)))))
In this endpoint, body(content(paragraph(elements(endIndex,startIndex,textRun(content,textStyle/link/url))))) is used as fields.
Sample response:
For example, when the following texts are put in a Google Document and def has a hyperlink,
abc
def
The response is as follows. From the following result, you can retrieve the position of text with the hyperlink can be retrieved. Using this, you can modify the hyperlink.
{
"body": {
"content": [
{},
{
"paragraph": {
"elements": [
{
"startIndex": 1,
"endIndex": 5,
"textRun": {
"content": "abc\n",
"textStyle": {}
}
}
]
}
},
{
"paragraph": {
"elements": [
{
"startIndex": 5,
"endIndex": 8,
"textRun": {
"content": "def",
"textStyle": {
"link": {
"url": "https://sample/"
}
}
}
},
{
"startIndex": 8,
"endIndex": 9,
"textRun": {
"content": "\n",
"textStyle": {}
}
}
]
}
}
]
}
}
Reference:
documents.get
batchUpdate requires to know position of text, we can get document with all content and find positions of links
In my case I implement it as:
Copy template to new place with final name
Replace link texts and other parts of text
Get document
Find links positions in doc
Update link URLs
Here example in nodejs
const {google, docs_v1} = require('googleapis');
async function replaceInDoc(doc) {
let documentId = 'some doc id'
let auth = 'auth value for user'
let linkNewUrl = 'https://github.com/googleapis/google-api-nodejs-client'
google.options({auth: auth})
var docs = new docs_v1.Docs({}, google)
// document should have link with http://repo-url.com text, we will update it
var requests = [
{
replaceAllText: {
containsText: {
text: 'http://repo-url.com',
matchCase: true,
},
replaceText: linkNewUrl,
},
}
]
var updateRes = await docs.documents.batchUpdate({
documentId: documentId,
resource: {
requests: requests,
},
});
var docInfo = await docs.documents.get({documentId: documentId})
var linkPos = findLinksInDoc(docInfo)
// set new url to link by position of link in the document
var requests = [
{
updateTextStyle: {
textStyle: {
link: {
url: linkNewUrl
}
},
range: {
startIndex: linkPos[linkNewUrl][0],
endIndex: linkPos[linkNewUrl][1]
},
fields: "link"
}
}
]
var updateRes = await docs.documents.batchUpdate({
documentId: documentId,
resource: {
requests: requests,
},
});
}
// returns hash as { 'http://example.com': [startPosition, endPosition] }
function findLinksInDoc(doc) {
var links = {}
doc.data.body.content.forEach(section => {
if (section.paragraph) {
section.paragraph.elements.forEach(element => {
if (element.textRun && element.textRun.textStyle.link) {
links[element.textRun.content] = [element.startIndex, element.endIndex]
}
})
}
})
return links
}
I search around here and little example to show how to search a json element in SwiftyJSON. I have below json structure, can anyone tech me? thanks.
var jsonData = {
"css":[
{
"path": "style.css",
"updated": "12432"
},
{
"path": "base.css",
"updated": "34627"
}
],
"html":[
{
"path": "home.htm",
"updated": "3223"
},
{
"path": "about",
"updated": "3987"
}
]
}
I want to search the "html" -> "home.htm" row. How to make use of filter method for it.
I got example like this for simple json structure, but in my case I have no idea.
{
countryid : "1"
name : "New York"
},
{
countryid : "2"
name : "Sydeny"
}
if let array = arrCountry.arrayObject as? [[String:String]],
foundItem = array.filter({ $0["name"] == "def"}).first {
print(foundItem)
}
let updated = json["html"].array?.filter { $0["path"].string == "home.htm" }.first?["updated"].string
print(updated)
// OR
for subJson in json["html"].arrayValue where subJson["path"].stringValue == "home.htm" {
let updated = subJson["updated"].stringValue
print(updated)
}
How to get Value Radio Name With Swift JSON
I wrote like this
let response = JSON["topradio"]["Data"]
before this i created model for values but am not able to pic values like radio_name
{
"topradio": {
"result": "success",
"Data": [
[
{
"radio_name": "Kantipur",
"rimage": "radio/1422960479145155755920731096211441695162.jpeg",
"status": "1",
"user_faverate": "false",
"popular_radio": "0",
"radio_id": "4"
}
]
[
{
"radio_name": "Kantipur",
"rimage": "radio/1422960479145155755920731096211441695162.jpeg",
"status": "1",
"user_faverate": "false",
"popular_radio": "0",
"radio_id": "4"
}
]
]
}
Thanks in Advance
You can iterate through your nested data Array this way.
let dataArray = JSON["topradio"]["Data"].array
for item in dataArray {
let itemArray = item.array
for subItem in itemArray {
if let name = subItem["radio_name"].string {
print(name)
}
}
}
I'm attempting to loop through a JSON array sending data to a struct.
Here's my code that uses SwiftyJSON to return a JSON object:
performAPICall() {
json in
if(json != nil){
print("Here is the JSON:")
print(json["content"]["clients"])
let clients = json["content"]["clients"]
for client in clients {
var thisClient = Client()
thisClient.id = client["id"].string
thisClient.desc = client["desc"].string
thisClient.name = client["name"].string
self.clientArray.append(thisClient)
}
self.tableView.reloadData()
} else {
print("Something went very wrong..,")
}
}
I'm not quite sure why I'm getting "has no subscript" errors on the three strings.
Any help appreciated, thanks.
EDIT: Here's a sample of the JSON
{
"content": {
"clients": [{
"group": "client",
"id": "group_8oefXvIRV4",
"name": "John Doe",
"desc": "John's group."
}, {
"group": "client",
"id": "group_hVqIc1eEsZ",
"name": "Demo Client One",
"desc": "Demo Client One's description! "
}, {
"group": "client",
"id": "group_Yb0vvlscci",
"name": "Demo Client Two",
"desc": "This is Demo Client Two's group"
}]
}
}
You should use array method. Thus, your line
let clients = json["content"]["clients"]
should use array (and unwrap it safely):
guard let clients = json["content"]["clients"].array else {
print("didn't find content/clients")
return
}
// proceed with `for` loop here
