Adding Array Data to Array Field Failing #93

aminediab · 2019-03-05T12:57:51Z

Hi Phill,
I have modified the diet plan class and added an ingredients array field, and successfully created the object. now when testing the add function I got an parse error on response with Unexpected token s in JSON at position 43, check the code below:

void addArray() async {
var list = ["sugar", "rice", "salt"];
var apiResponse = await DietPlan().getObject('j2S0JZhbpC');
if (apiResponse.success && apiResponse.result != null) {
var dietPlan = (apiResponse.result as DietPlan);
var response = await dietPlan.add('ingredients', list);
dietPlan.save();
} else {
print('ERROR');
}
}

That looks correct to me? Can you send the log through please?

Is this what you want?

Yes, it wasn't as helpful as I hoped though, ha. I will look into this shortly for you.

aminediab · 2019-03-05T14:31:24Z

Phill, I think it is apparently trying to parse something that isn't Json, that's my take on it!

phillwiggins · 2019-03-08T14:35:01Z

Hey, I think this might have been fixed by one of our contributors. Can you try again please?

RodrigoSMarques · 2019-03-08T14:54:27Z

Hi @phillwiggins. I did the fix and it's tested.

@aminediab, The correct way to implement is:

void addArray() async {
var list = ["sugar", "rice", "salt"];
var apiResponse = await DietPlan().getObject('j2S0JZhbpC');
if (apiResponse.success && apiResponse.result != null) {
var dietPlan = (apiResponse.result as DietPlan);
var response = await dietPlan.add('ingredients', list);
//dietPlan.save();
} else {
print('ERROR');
}
}

aminediab · 2019-03-08T17:46:38Z

Hi Phill & Rodrigo,

The ERROR persists. The first portion; the apiResponse is a success and it returns the object correctly, however adding fails with a Parse Error, (Unexpected token s in JSON at position 43)
can you confirm how you have tested it?

thanks,

aminediab · 2019-03-08T17:55:00Z

Just to be clear, the add operation should append the list to the array field, i have manually entered a string list in the ingredients field and then ran the code as suggested!

RodrigoSMarques · 2019-03-08T17:55:48Z

@phillwiggins
Do not you have to release a new release with the changes?
I noticed that they are only in Branch: Master.

Do you know if it is possible to use the master instead of a release?

phillwiggins · 2019-03-08T17:59:05Z

Maybe try this?

parse_server_sdk:
git: git://github.com/phillwiggins/flutter_parse_sdk.git

RodrigoSMarques · 2019-03-08T18:07:12Z

@aminediab
update pubspec.yaml to :

dependencies:
flutter:
sdk: flutter
#parse_server_sdk: ^1.0.15
parse_server_sdk:
git: git://github.com/phillwiggins/flutter_parse_sdk.git

Try again.

Sample yy code:
_apiResponse = await objeto.add("lista", ["a", "b", "c"]);
if (apiResponse.success) {
print(apiResponse.result.toString());
} else {
print(apiResponse.error.toString());
}

apiResponse = await objeto.addUnique("lista", ["a", "a","d"]);
if (apiResponse.success) {
print(apiResponse.result.toString());
} else {
print(apiResponse.error.toString());
}

apiResponse = await objeto.addUnique("lista", ["a", "d", "e"]);
if (apiResponse.success) {
print(apiResponse.result.toString());
} else {
print(apiResponse.error.toString());
}
apiResponse = await objeto.addUnique("lista", ["f"]);
if (apiResponse.success) {
print(apiResponse.result.toString());
} else {
print(apiResponse.error.toString());
}

apiResponse = await objeto.remove("lista", ["d","e"]);
if (apiResponse.success) {
print(apiResponse.result.toString());
} else {
print(apiResponse.error.toString());
}_

My log:
flutter: {lista: [a, b, a, b, c], updatedAt: 2019-03-08T18:04:05.788Z}
flutter: {lista: [a, b, a, b, c, d], updatedAt: 2019-03-08T18:04:05.931Z}

Let say, if i use the following method to add array. It's working.

var manage = ParseObject('Test')
..set('name', "Test")
..set('email', "test@mail.com")
..set('age', 15)
..setAdd('hobby', ['Play Chess', 'Watch Movies']);
await manage.save();

This saves my values in the Back4App database. But, when i try following code to update my class values,

var manage = ParseObject('Test')
..objectId = widget.id
..set('name', "Test")
..set("email", "test@mail.com")
..set('age', 18)
..setAdd('hobby', ['Travel', 'Fight']);
await manage.update();

Above code doesn't update my current object/list anyway. How to update parse objects and parse list for back4App ?

Thanks.
But, it's not updating my object

phillwiggins · 2020-07-24T05:39:38Z

Hey Mungra. If you create an instance of a ParseObject, then save it, your ParseObject will be assigned an objectId. Once you have created your object and saved it, manipulate the same object in whatever way, then call update. Does that work? At the moment you are simply creating 2 new objects instead of updating the same one, I think?

MungaraJay · 2020-07-24T06:45:00Z

@phillwiggins

I have tried updating the same reference as well. like,

ParseObject('Employee')
..objectId = widget.id
..set('name', nameController.text.trim())
..set("email", emailController.text.trim())
..set('age', ageController.text.trim())
..setAdd('hobby', ['Travel', 'Fight'])
..update();

But, it doesn't work.

So, Can you please add that line of code here?

phillwiggins · 2020-07-24T07:51:33Z

var manage = ParseObject('Test')
..set('name', "Test")
..set('email', "test@mail.com")
..set('age', 15)
..setAdd('hobby', ['Play Chess', 'Watch Movies']);
await manage.save();

manage
..setAdd('hobby', ['Travel', 'Fight'])
await manage.update();

Something like that should work?
