I've been trying for hours to make it work and I can't do it, I hope some of you have the answer to my question because it must be very simple and I am a beginner
I am using AngularJs and NestJs in Nest used the #nestjsx/crud and I went trow the request docs so, here is the problem:
This is my Angular service function
getProductsOfPiece(pieceId: number): Observable<ProductSimple[]> {
return this.http.get<ProductSimple[]>(
'api/producto/', {
params: {
fields: "id,refFabr,refCliente,descrCorta,imagen",
filter: 'pieza.id||$eq||'+ pieceId
}
}
);
}
This request gives me a 400 Bad Request, it looks like this:
/api/producto/?fields=id,refFabr,refCliente,descrCorta,imagen&filter=pieza.id%257C%257C$eq%257C%257C1
I imagine the % and the hexadecimal have something to do with the URI coding and tried to encode/decode it, but didn't work.
I also tried using the class RequestQueryBuilder of #nestjsx/crud-request from the FrontEnd usage referenced in the docs, and append it to the URL
let queryString = RequestQueryBuilder.create()
.select(["id","refFabr","refCliente","descrCorta","imagen"])
.setFilter({
field: "coleccion.id",
operator: CondOperator.EQUALS,
value: collectionId
}).query();
return this.http.get<ProductSimple[]>(
'api/producto/?'+queryString
);
but got worse result
/api/producto/?fields=id%2CrefFabr%2CrefCliente%2CdescrCorta%2Cimagen&filter%5B0%5D=pieza.id%7C%7C%24eq%7C%7C1
What I don't understand is how I do this with my Postmand and it works!
api/producto/?fields=id,refFabr,refCliente,descrCorta,imagen&filter=coleccion.id||$eq||6
How can I make it work, what is wrong with my code?
Finally got the answer, just had to set the .query(false) on the RequestQueryBuilder, this boolean parameter is for encode, seams like Angular's HttpClient class does some encoding or something to the URL so, anyway
It Works! Here is the code:
getProductsOfPiece(pieceId: number): Observable<ProductSimple[]> {
let queryString = RequestQueryBuilder.create()
.select(["id","refFabr","refCliente","descrCorta","imagen"])
.setFilter({
field: "coleccion.id",
operator: CondOperator.EQUALS,
value: collectionId
}).query(false);
return this.http.get<ProductSimple[]>(
'api/producto/?'+queryString
);
}
And you need to import
RequestQueryBuilder of #nestjsx/crud-request
npm i #nestjsx/crud-request.
Any observations are welcome...
UPDATE
To create or update
Here are de docs
Create One https://github.com/nestjsx/crud/wiki/Controllers#create-one-resource
Update One https://github.com/nestjsx/crud/wiki/Controllers#update-one-resource
Following that guide the create and update are simple
Just do POST to the API 'api/producto/' (for example) with the object as body in the request
For the Update follows similar just using the PUT method and the API with the model id 'api/producto/1' (for example)

I'm new in Gatling, and trying to get value from json key.
This check give me labels:
.check(jsonPath("$[1].ppp[1].label").saveAs("label"))
In this request i got all json data like this
[
{
"id":258,
"code":"D00CC3056",
"label":"Test-0"
},
{
"id":260,
"code":"D00RR148",
"label":"Test-1"
}
]
From this Json, i need to get code value from a specific label, to use it in request after.
Something like : get code where label is "Test-1".
I've trying this but doesn't works:
.exec(
http("request_3:GET_/api/code")
.get("/api/code")
.check(status.is(200))
.check(jsonPath("$..[*].code").find("{$label}").saveAs("code"))
)
I don't know how to do this.
Any help ?
With JMESPath that you should really learn and that Gatling supports:
.check(jmesPath("[?label == 'Test-1'].code").saveAs("code"))
For ref, using "#apollo/client": "^3.5.5",
I've defined my typePolicies like so as suggested in docs:
HistoricalData: {
keyFields: ["variable", "workspace"],
fields:{...}
}
and when my cache is built, I am expecting my cacheId to be like
<__typename>:<id>:<id>
HistoricalData:${props.variable}:${props.workspace}`;
but instead, when I look in the Apollo cache, it's been created using the keyField names and the values in an object, such as
HistoricalData:{"variable":"GAS.TOTAL","workspace":"ABC"}
instead of
HistoricalData:GAS.TOTAL:ABC
so when I try to readFragment it returns null
client.readFragment({
id: `HistoricalData:${props.variable}:${props.workspace}`,
fragment: apolloGQL`fragment MyHistorical on Historical {
variable
workspace
}`})
It does actually return a value from the cache if I create my id in the structure that exists in the cache and readFragment using this.
Has anyone else noticed that Apollo client is not creating the cache id's in the structure that they describe in the docs?
After some research I came upon the correct way to handle this case. I know that you have already moved on, but just in case anyone else has the same problem in the future, here goes:
As described in the documentation for customizing the cache ID, the cache ID will be an stringified object, as you pointed out. It's not quite explicit in the documentation, but at this point in time it provides this nested example for a cache ID:
Book:{"title":"Fahrenheit 451","author":{"name":"Ray Bradbury"}}
But as users we don't have to preoccupy us with the format of this ID, because there's a helper for that, called cache.identify.
For your specific case, you could use something like this:
const identifiedId = cache.identify({
__typename: 'HistoricalData',
variable: 'GAS.TOTAL',
workspace: 'ABC'
});
cache.readFragment({
id: identifiedId,
fragment: apolloGQL`fragment MyHistorical on Historical {
variable
workspace
}`
});
I have seen 100 examples of passing an ID into $resource.get() in order to query information out of a back-end in Angular. What I have not been able to find is how to pass a complex object.
If I have a table of objects to return, and I wish to run a search against them using multiple items of filter, I need to pass those items as parameters or as one complex parameter. For example, say I have a table of people's names and their cities, states, etc. I want to be able to say something like this:
var myResource = $resource(url);
myResource.get({name : "Mike", state : "Texas"});
The return may be a single row or multiple rows. But the point is how do I get the parameters off to the API call?
The way I have other methods set up that are simpler is by creating a repository in which I return like so:
return resource('/api/broker/productionInfo/');
Then in my API I do this (after the [RoutePrefix("api/broker")] setup:
[HttpGet]
[Route("productionInfo")]
public IHttpActionResult GetProductions()
{}
That's all awesome but I want to be able to add the search criteria in the repository call and then in the API method (i.e. extract from a querystring or however it is to be passed).
If I understand what you are asking correctly, you just want to pass additional parameters into an angular resource get request. It is as simple as what you have already suggested:
resource.get({id: 1, custom_param_1: "param1", custom_param_2: "param2"});
This would result in an http request that looks like this:
/resource/1?custom_param_1=param1&custom_param_2=param2
You can then extract these parameters on the API side of things.
Something to note is that get requests have a maximum length, and if you are attaching lots of different parameters to the request, it may be better to use a post or put instead.
The only thing I'm seeing that you're missing is a [FromUri] decorate attribute, in your GetProduction API method. Since Get supports only params binding through a query string (no body binding).
Your params:
options: {
StartDate: _startDate
EndDate: _endDate
TextSearch: "some search query....",
Page: 1,
PageSize: 25,
et...
}
Then, calling your repository from your controller:
repository.get(options).$promise.then(function (data) {
// data = response payload from backend
});
reposiroty
....
return resource('/api/broker/productionInfo/');
....
API
[HttpGet]
[Route("productionInfo")]
public IHttpActionResult GetProductions([FromUri] SearchCriteriaModel criteria) {
....
}
Hope that helps.
I have read and worked with the other posts about this and it appears the version of Laravel 4 I just downloaded has more changes made to the way the JSON input is handled by a controller.
$input = Input::json()->all(); gives me errors as if I am referring to something that does not exist when I request some part of the payload after doing a PUT request. And without ->all(); I get a symfony error.
Does anyone know how to get good JSON from backbone in Laravel 4's latest version?
Currently, I am doing the long way around to get my data, ie:
$input_title = Input::get('title');
$input_completed = Input::get('completed');
$task = Task::find($id);
$task->title = $input_title;
$task->completed = $input_completed;
$task->save();
Yes, I am doing the tutorial on tutsplus to learn laravel/backbone, so a little noob patience is apreciated.
The error I get when using Input::get(); is:
{"error":{"type":"UnexpectedValueException","message":"The Response content must be a string or object implementing __toString(), \"array\" given.","file":"/Users/brentlawson23/Sites/laravel4App/bootstrap/compiled.php","line":16858}}
I really want to get the Laravel-specific answer instead of using straight php to stringify the payload.
I get same error using just Input::json();
For the current beta of Laravel 4, Input::json(); is not getting a stringified version of the request payload that can be used to create a new row in a table, nor does Input::json()->all(); (hoping to play nice with the ParameterBag from symfony). I have tried json_encode among other hacks and basically every step of the way in this tut, I hit some brick wall. Anyone have a suggestion based on what I have presented here?
Today I got this when simply trying to echo the result of $input = Input::json(); :
{"error":{"type":"ErrorException","message":"Catchable Fatal Error: Object of class Symfony\Component\HttpFoundation\ParameterBag could not be converted to string in /Users/brentlawson23/Sites/laravel4App/app/controllers/TasksController.php line 45","file":"/Users/brentlawson23/Sites/laravel4App/app/controllers/TasksController.php","line":45}}
Yes, I have studied the Symfony API.
I had a similar problem. Input from Backbone is converted to array in Laravel. On tutsplus, Jeffrey Way is using object. So I was trying to do this (like in tutorial):
return $input->title // using object,but got an error.
If I change that line to:
return $input["title"] // everything works fine with array.
I'm also working through the Backbone tutorial on tuts+. If I'm right in assuming are you stuck on the Creating New Contacts section? Below is how I got it to work for me, in ContactController.php:
public function store()
{
$input = Input::all();
Contact::create(array(
'first_name' => $input['first_name'],
'last_name' => $input['last_name'],
'email_address' => $input['email_address'],
'description' => $input['description']
));
}
And then also needed to update app/models/Contact.php with the below:
class Contact extends Eloquent {
protected $fillable = array('first_name', 'last_name', 'email_address', 'description');
}
That should get it working for you and insert the contact into the database. If I've misread let me know and I can have another look.
Cheers,

I have been trying out backbone.js and have been stymied when I create a new model object then call model.save(). I am expecting the backbone.js default behavior to update the model object with the id from the database but it is not. Is this not supposed to happen? I have verified that I am getting a post with the attributes in json format. My server saves the json to a table and then returns the json with a new id field to backbone.js. Is this correct? Should my server return the entire new object or just the id or what?
//contents of the POST from backbone.js
{ "text":"this is a test" }
//reply from my server
{ id:"15", text:"this is a test" }
My sample code is below
var SQLRow = Backbone.Model.extend({
table:"",
urlRoot:'db',
url:function () {
return "/" + this.urlRoot + "?table=" + this.table +
"&id=" + this.attributes.id;
}
});
var Xtra = SQLRow.extend ({
table:'Xtra'
});
var row = new Xtra({
text: "this is a test"
});
alert(row.url());
row.save()
alert("row:" + row.get("id"));
Tough to tell from your post. Two ideas :
1) the response from the server isn't successful What does your save call return ?
2) Your "id" attribute is named something other than ID. To account for the different name add the following to your model :
idAttribute : "MyModelsID",
EDIT
You're likely facing a timing issue, where the alert fires before the ID has returned. Instead of your last two lines try this :
row.save( null,
{
success : function(model, response) { alert(model.get('id'); }
}
);
ALTERNATIVE
As #mu_is_too_short mentioned, another way is to listen for the change even on the model and respond to the event. (i was just trying to keep the answer as close to your code as possible). But something like the following pseudo code should get you started...
var myView = Backbone.View.extend({
....
initialize : function () {
this.collection.bind('change', this.SOME_LISTENING_FUNC );
}
});
OR, if you're in a collection/view-less world something like this creates a listenr ...
row.on('change', function() { /* do stuff */ }, this);
This answer is based on one comment of Cjolly in the answer above.
It is essential for making the Backbone.Model.save([attributes],[options]) successful in assiging the model with the newly generated model's id from the server, that the server returns the model's id in a JSON string like this { "id" : <the id> }. (note it is "id" and not id).
In essence backbone rightly expects a JSON string and in contrast to how objects may be defined in Javascript without quoted keys, JSON requires the object keys to be quoted (see JSON Spec - does the key have to be surrounded with quotes?)
Since according to Cjolly's comment this has been the essential problem, I want to hightlight this solution in an second answer. Partially because I was hit by the very same problem and only by reading througth the comments I was able to receive the insight.
I've faced the same issue and what I've found is that my validate function of the saved model actually invalidates the model returned from the back end. That's why my fields were not updated properly.
Maybe its a little outtimed, but today I had the same missing id.
It turns out, that the server just sends a Header 'Location' with a redirect containing the new id, but dosen't return the persisted object.
Adding the object to the response was the solution.
It seems, that not returning the object is standard behavier with Roo(Spring) generated Json-Controllers.
