In this https://developer.gooddata.com/article/data-modeling-api there is a logical data model and its corresponding JSON. However, I can't seem to find out how to extract JSON from a logical data model via the REST API. Is there a way to do this other than using the single load interface (which would be very inefficient)?
For the record, my end goal is to make a tool that extracts that JSON (which would be in dev), then post that to the ldm manager2, and then apply the suggested changes through the returned MaQL to production. Any help is greatly appreciated
Currently this works only for Getting or Updating the entire Project. Anyway you can GET all model definition by simple API call. See the documentation:
http://docs.gooddatadrafts.apiary.io/
There is a GET request which is asynchronous. You can build some logic on the top of that on your end. You can get all models, store per datasets information, but at the end you need to POST the "final version" and all updates will be applied.
Let me know if I can help you with anything!

I'm making a website that gets its info from a RESTapi I've written and hosted myself, have had no data problems thus far.
Now I'm trying a simple retrieve of a json object and I get all the info correctly as shown here in the API. (Visualized & tested in Swagger)
As you can clearly see, it retrieves it the complete object and underlying objects correctly (blurred sensitive info).
Pay attention to the property "AmountOfEggs" though.
Now when i call this api endpoint (exactly the same way) in my site and console.log the result.data, this is the feedback.
Now for some reason I can't recieve AmountOfEggs in my frontend.
I've recreated the entire object, wrote different names, passed different props (Id, NumberBus, etc are passed in this situation with no problem, which are also int (number) types).
I have no idea why this property gets "dropped" in the transfer and filled with/defaults to an empty string.
Any help would be greatly appreciated.
I found where it went wrong and it's due to different factors.
To start, I am making this site using the Vue framework, which has reactive components, which means, data gets adjusted and you get live updated components on your views/pages.
In the page that contained the call, I also wanted to add dynamic styling. The code I used for this is the following:
v-for="seller in retrievedSellers"
:key="seller.Id"
:class="[
'sellerStyle'
, (seller.AmountOfEggs = 0 ? 'grey-out-seller' : ''),
]"
Now two things to note, first of all this might look like backend coding but this is Vue logic on the .vue file which handles the dynamic options that Vue provides so I never thought to look here for the error.
The error of couse is the 'seller.AmountOfEggs = 0' part, using one equal sign (assignment) instead of two (comparison).
So I learned,
Vue doesn't throw errors on assignments in code that is used to generate frontend (where you should NEVER alter your data).
My console.log was the moment the response of the API came in, where apparently it was already assigned a new value (due to my code above) before hitting the console.log.
It still greatly surprises me that Vue handles ^this^ first to make sure your reactive components are up to date before finishing the api call itself.
However, I still don't understand how it said "" instead of 0.
I'm using typescript (javascript strongly-typed) so it definitely wants to contain a number and not an empty string. Even in the declaration of my DTO the property is defined as (and expects) a number.
I have an API that produces JSON like this:
)]}',
{
//JSON DATA
}
The //JSON DATA is valid JSON, but the )]}', up top is not.
When I try to GET this data via a Logic App, I get:
BadRequest. Http request failed: the content was not a valid JSON.
So, a few related questions:
1) Can I tell the logic app to return the invalid JSON anyway?
2) How can debug the issue better? I happen to know that the response is invalid, but what if I didn't? Can I see the raw data somewhere?
3) This is all done via the Azure web portal. Are there better tools? Visual Studio?
I should also mention that if I call a route on the same API that returns XML instead of JSON, then the Logic App works fine. So it definitely doesn't like the JSON response in particular.
Thanks!
First of all, please do not post three questions as a single question.
Question 1). The best thing you can do is make the API return a valid JSON object. This is good for million reasons. Here're a few:
it's pretty much a standard (either valid JSON or XML -- yeah, old school way);
therefore, no users of this API (including you) will need to struggle and guess what's going on and why;
your Logic App's step will just work without adding extra complexity;
you will make this world and your karma better.
If API-side changes are not within your reach, I don't think you can do much. If you're lucky and the HTTP action is successful (Status Code 2xx), you can try to use a Query Action with a function that truncates the first characters. It will look something like this (I don't know the exact syntax): #Substring(body('myHttpGet'), 4, length(body('myHttpGet')) - 4) where myHttpGet is the id of the Http Get action.
However, once again, if possible, I strongly recommend fixing up the API which is the root cause of the problem, instead of dealing with garbage response after that.
UPDATE Another thing you can do is wrap the dirty API. For example, you could create a trivial Azure Function that invokes the API you don't directly control, and sanitizes the response for you consumption requirements. This Azure Function function should be easy to call from the Logic App. It costs almost nothing (unless we're talking millions of requests/month). The only drawback here is the increasing latency, which may be not an issue at all -- test it and see whether it adds less than 100ms or so... Oh, and don't forget to file a ticket with the API owner, they make our world a bad place!
Question 2) In Azure Logic App web UI you can Look into the execution details and the error will definitely be there.
Question 3) You're asking for a tool recommendation which is by definition a highly subjective thing and is off-topic on StackOverflow.
TL/DR: The other app is not producing valid JSON.
Meaning, this is not a problem for you to solve. The other app has to return valid JSON if the owner claims it should.
If they cannot or will not produce valid JSON, then the first thing you need to do is inform your management that you will have to spend a lot of extra time accommodating their non-standard format.
We are currently trying to set up routes in such a way that the returned content-type can be set using a route parameter. The routing is all working properly now, but there is one problem. If one requests html, then the normal view script is rendered. The data we provide to this script can be anything from a string to a collection of objects, and the view script decides what to show to the user.
If however JSON response is requested, then we just provide the data returned from our controller as JSON. However, some data should not be made publicly available to the user, and hence some filtering is required. Is there any possibility to use JSON view scripts (as in ZF1 with context-switch) in order to support such filtering? Or maybe another method?
There is no such thing as a JSON script which lets you decide what to render and what not. You have to provide the proper data in the view model such that only the data is given that is eligible to be displayed.
I have been thinking about a hook in the JSON renderer so you can filter the view model's data based on the context of the request, but such thing does not exist yet. Unfortunately, you have to select the data in your controller or model.
I've been using Google Tools (library, templating) for almost a year... and I came to the point where a I have to connect the backend with all the templates i've been working on. The backend receives the data in JSON format.
Here's my problem. I want to submit a JSON that represents my object model in the backend and I know closure library offers this...
var json = goog.json.serialize(goog.dom.forms.getFormDataMap(form).toObject());
Problem is that the method getFormDataMap returns a goog.structs.Map which works like a hashMap... It means that all values of the form submitted are nested into arrays.
I was wondering if anyone has found a solution to this. I know that there is some library that does the trick like this one (https://github.com/maxatwork/form2js) but I can't believe that closure doesn't have anything to deal with this problem.
Thanks a lot !
why not access the data yourself and build the data structure you require, it is not like this will be a bottleneck of any sorts.
I'm working on a custom control that will be fed by JSON content and I'm trying to find the best approach to produce and consume it.
Let say the JSON could be from:
Notes View (all documents)
Notes View (subset of documents based on a category or filter)
Notes Document Collection (from database.Search or database.FTSearch)
What I have on my mind is to define some Custom Properties where I can define:
URL that produces the JSON
Object
etc.
So far I'm considering:
REST Service control from ExtLib
XAgent that produces JSON
Domino URL ?ReadViewEntries and OutputFormat=JSON
Does anyone knows if the JSON object loaded in memory has a size limit?
Any suggestion will be appreciated.
Definitely go for the REST Service control from the Extension Library, offers by far the best combination of flexibility vs performance vs development time.

What about creating the JSON in the view itself and then just read the column values? http://www.eknori.de/2011-07-23/formula-magic/
If you want to parse the json object using ssjs, you can fetch it using an URLConnection and put the resulting object into a repeat control using the eval statement.
