I have a simple DataGrid that gets the Data from a JSON file hosted on a server.
I am using the build Data Connection Wizard and it works great.
Now I want to let the user manipulate the data and send it back to the JSON file.
I tried to add a form to the data grid but it changes only the data on the application and it is not influencing the file on the server.
any help or direction how should i do that will be appreciated.

Im currently working on a new design for a mobile app (only frontend). In the project I need to use states to change the css of a button. If the button has changed, next time the app is refreshed the state should be as you left it.
That is why I have a locally stored JSON file that is structured the same as how the apps current database is. Reading it is no issue, but I can't get the writing to work.
How I read the JSON:
const jsonData = require('../data.json')
function GetBaseState(id){
console.log(jsonData.bases[id].state)
}
How would I go about changing that state in the JSON file?
In order to both of reading and writing Json file , you are able to use react-native-fs. For example by readFile method you can read json file and by writeFile method writing your json file in local storage.
react-native-fs have good documents that you are able to reading that for more information and usage.
1) I have already made transformation mapping for getting data from specific MySQL (Table Input) and convert it as Text File output.
2) Also I have created a facebook developer account page and trying to figure out how the Facebook API works to push data from MYsql to facebook.
3) would appreciate if transformation mapping can be provided. Also I would not like to use XML, instead I would like to use JSON.
Already the msql table is converted to csv file, but I am not sure how to post the csv file to facebook or is there a way to connect mysql table to facebook directly. Please share your ideas or transformation mapping. Thanks
I would Assuemm you are familiar with Facebook Development API to do all actions like post,get and so on.
You have a step called "REST CLIENT STEP" in Pentaho.
you will have an API url to post the data that you want from mySQL. There several methods GET PUT POST DELETE
Also set the Application Format to Json (XML,JSON etc).
I used to read data from FB using REST Client by using GET Method. Work around.
I am new to Node.js ,with the help of this
tutorial I've learned how to write REST API using Node.js .Can anybody please help me to understand how to upload an image file using Node.js and saving it in mysql table ? I've been searching for it , but couldn't get something useful . Any help would be useful to me.
Typically files are uploaded as multipart form data from a web page. You could start there with a simple <input type="file"> on a web page.
Create an endpoint in Express, and consider a package to help parse it. One like express-formidable would be a good start. Then you will have the file from the request.
To save to mysql, I'd suggest the package knexjs. This is a nice library to programmatically write SQL queries. You'll have to define your own tables that store the image (probably as BLOBs) and you can use Knex to store the new images into your DB.
Be aware of the asynchronous flow in NodeJS. For your Express endpoints, you only want to finish the response after the DB code is done, like inside the knex call's callback (or at the final .then() of a promise chain)
I am trying to build an Employement Management App in AngularJS where a basic operation is adding an employee.
I am displaying details using a service and getting Json data from the mock json file i am using.
Similarly, can i add form data to a textfile on the harddisk.
I have seen it done in a tutorial using $resource.save.
If at all it is possible without any server side code please share the example,it would be helpful.
Thanks.
You can make use of HTML5 local browser storage, as this does not require folder access. Mode datails here http://diveintohtml5.info/storage.html
AngularJS has modules for local storage which you can use to access such storages like this https://github.com/grevory/angular-local-storage
Busy building a website for a client using classic ASP (It will reside on an old server) which is going to be used internally only.
The admin is able to view a paginated table of data and export this to CSV. This works fine when I save the CSV data to a CSV file but I have now been asked to try avoid the creation of the file if possibly and create the CSV in memory without the need for a file.
I have my doubts that this is possible but might be completely wrong. Is there anyway to send the CSV data to the browser such that it will open in Excel rather than having to create a CSV file and link to it as I am currently doing ?
TIA

Response.ContentType = "text/csv" will help you here. In the past I've paired that with a rewrite rule so that the URL is something like foo.com/example.csv but there are plenty of other ideas to be found in the following question: Response Content type as CSV
