I'm currently working on ng-admin.
I'm having a problem retrieving user data from my REST API (connected to a MongoDB) and displaying it.
I have identified the problem as the following:
When I enter http://localhost:3000/users into my browser, I get a list of all users in my database.
When I enter http://localhost:3000/users?_page=1&_perPage=30&_sortDir=DESC&_sortField=id,
I get [] as a result.
I am quite new to this, I used both my browser and the POSTMAN Chrome extension to test this and get the same result.
http://localhost:3000/users_end=30&_order=DESC&_sort=id&_start=0
This (/users_end) is a different request than /users.
It should be:
http://localhost:3000/users?end=30&_order=DESC&_sort=id&_start=0
Or, by looking at the other parameters:
http://localhost:3000/users?_end=30&_order=DESC&_sort=id&_start=0
with end or _end being the first parameter (mark the ?).
Update (it is ? and before the _, I have edited.):
If adding parameters to the request returns an empty list, try adding only one at a time to narrow down the problem (there's probably an error in the usage of those parameters - are you sure you need those underscores?).
Your REST API must have a way to handle pagination, sorting, and filtering. But ng-admin cannot determine exactly how, because REST is a style and not a standard. So ng-admin makes assumptions about how your API does that by default, that's why it adds these _end and _sort query parameters.
In order to transform these parameters into those that your API understands, you'll have to add an interceptor. This is all thoroughly explained in the ng-admin documentation: http://ng-admin-book.marmelab.com/doc/API-mapping.html

I am trying to retrieve a value from a HTTP web service call in sharepoint designer. This should be simple. the Rest query is simple, and always returns only a single value:
https://Site.sharepoint.com/sites/aSiteName/_api/web/lists/getByTitle('MyListTitle')/items/?$select=Title&$top=1
In the Sharepoint Designer workflow, I'm setting the required Accept and Content-type header to the value of "application/json;odata=verbose
I am unable to get the value of the "Title" field that is returned by the call.
when I execute the REST query in the browser, I get the following data returned:
{"d":{"results":[{"__metadata":{"id":"af9697fe-9340-4bb5-9c75-e43e1fe20d30","uri":"https://site.sharepoint.com/sites/aSiteName/_api/Web/Lists(guid'6228d484-4250-455c-904d-6b7096fee573')/Items(5)","etag":"\"1\"","type":"SP.Data.MyListName"},"Title":"John Doe"}]}}
I've tried dozens of variations of the dictionary 'query', but they always return blank.
I'm using the 'get an item from a dictionary' action in SP Designer, using item name or path values like:
d/results(0)/Title
d/Title
d/results/Title
and literally dozens of other variations - but it always returns blank.
I'm writing the raw response from the webRequest to the list for debugging, and it shows the value like this:
{"odata.metadata":"https:\/\/site.sharepoint.com\/sites\/aSiteName\/_api\/$metadata#SP.ListData.MyListTitle&$select=Title","value":[{"odata.type":"SP.Data.MyListTitle","odata.id":"616ed0ed-ef1d-405b-8ea5-2682d9662b0a","odata.etag":"\"1\"","odata.editLink":"Web\/Lists(guid'6228d484-4250-455c-904d-6b7096fee573')\/Items(5)","Title":"John Doe"}]}
I must be doing something simple that is wrong?
Using "d/results(0)/Title" is right. Check the steps in article below to create a workflow.
CALLING THE SHAREPOINT 2013 REST API FROM A SHAREPOINT DESIGNER WORKFLOW
It working fine in my test workflow.
I faced the exact same issue. In my case the reason was that in the API call, the header was not set properly.
As you would have noticed many times, that if you type the variables inline when creating the "Call Http Web service" action, those might not get set properly. The surest way is to open the properties and set from there. In my case when i opened the properties i found that RequestHeaders was not set. Once i set it from there, i got the desired results.
Hope this helps to someone in future, this question being unanswered till now!!
tried dump those json called from sharepoint workflow into a list. Sometimes you'll get a different format than when you called that from browser. I experienced this issue when calling API projectserver (project online). When I called it using servistate (chrome extension) it returns d/results, but when I dump the value into the list I got value and yet I used same request header value.
We are currently trying to come up with a set of REST API that would fit our resource models.
A simplified example of the resource is:
CompanyInfo: {
totalNumberOfEmployees: Number,
employees: [...employees],
}
Employee: {
name: String,
}
In this case, "CompanyInfo" is like a virtual resource that does not exist in DB. It is a short cut for getting all the data related to the Company resource. The idea was to reduce the amount of logic on FE and create more convenient endpoint instead.
Our current endpoint design is:
GET /api/companyInfos/{companyId}/employees
GET,POST,PUT,DELETE /api/companyInfos/{companyId}/employees/{employeeId}
The reason for the extra {companyId} is because these endpoint does not return "Employees", it instead return a "CompanyInfo" that contains "Employees" embedded in the payload.
This is to avoid the aggregated property "totalNumberOfEmployees" not being updated in case sync when we call POST to create a new "Employee"
So my questions are:
Is this the correct approach to the problem of "too many requests" or "too much logic in FE"?
Is it acceptable for the endpoint to return a completely different resource than what its url describe?
Thanks a lot :)
For your Fist question
Is this the correct approach to the problem of "too many requests" or "too much logic in FE"?
yes Sometimes this is how it is suppose to be done. when data sent is small in each request. to many request does not affect the performance so This is how it is suppose to be done .
And Generally it is recommended to write one monolithic Ajax call in front end which will be capable of making any kind of call , By taking callback as parameter, and method , arguments as parameters .
So it will not be to much of logic if you follow this approach . All you have to write is callback for each of Ajax call . How ever sometimes situation may not allow for this Example:if you are using content-type like 'multipart/mixed'
there you have to write another ajax call code
However nowdays most front end has too much of logic based on how interactive website is . So your primary concern should be about look of web site .
For you second question
Is it acceptable for the endpoint to return a completely different resource than what its url describe?
yes . It is acceptable . but it is recommended that client mention all the MIME types which it expects in Accept header and Only those MIME types should be returned by Api.
I'm running into a problem with adding a query to the callback URL. I'm getting an invalid URI scheme error attempting to authorize the following string:
https://www.linkedin.com/uas/oauth2/authorization?response_type=code&client_id=75df1ocpxohk88&scope=rw_groups%20w_messages%20r_basicprofile%20r_contactinfo%20r_network&state=7a6c697d357e4921aeb1ba3793d7af5a&redirect_uri=http://marktest.clubexpress.com/basic_modules/club_admin/website/auth_callback.aspx?type=linkedin
I've read some conflicting information in forum posts here. Some say that it's possible to add query strings to callbacks, and others say that it results in error.
If I remove ?type=linkedin, I can authorize just fine and receive the token. It would make my life so much easier if I could use a query string on the callback url, as I need to do some additional processing in the callback.
In short, can I append a query string to the end of the callback url?
For fun, I tried encoding the callback url in the request (obviously this is a no-no according to their documentation):
https://www.linkedin.com/uas/oauth2/authorization?response_type=code&client_id=75df1ocpxohk88&scope=rw_groups%20w_messages%20r_basicprofile%20r_contactinfo%20r_network&state=5cabef71d89149d48df523558bd12121&redirect_uri=http%3a%2f%2fmarktest.clubexpress.com%2fbasic_modules%2fclub_admin%2fwebsite%2fauth_callback.aspx%3ftype%3dlinkedin
This also resulted in an error but was worth a shot.
The documetation here: https://developer.linkedin.com/forum/oauth-20-redirect-url-faq-invalid-redirecturi-error indicates that you CAN use query parameters. And in the first request, it appears that I'm doing it correctly. Post #25 on this page - https://developer.linkedin.com/forum/error-while-getting-access-token indicates that you have to remove the query parameters to make it work
Anyone have experience with successfully passing additional query paramaters in the callback url for the linkedin API using oAuth2.0? If so, what am I doing wrong?
I couldn't wait around for the Linkedin rep's to respond. After much experimentation, I can only surmise that the use of additional query parameters in the callback is not allowed (thanks for making my application more complicated). As it's been suggested in post #25 from the question, I've tucked away the things I need in the "state=" parameter of the request so that it's returned to my callback.
In my situation, I'm processing multiple API's from my callback and requests from multiple users, so I need to know the type and user number. As a solution, I'm attaching a random string to a prefix, so that I can extract the query parameter in my callback and process it. Each state= will therefore be unique as well as giving me a unique key to cache/get object from cache..
so state="Linkedin-5hnx5322d3-543"
so, on my callback page (for you c# folks)
_stateString=Request["state"];
_receivedUserId = _stateString.Split('-')[2];
_receivedCacheKeyPrefix = _stateString.Split('-')[0];
if(_receivedCacheKeyPrefix == "Linkedin") {
getUserDomain(_receivedUserId);
oLinkedIn.AccessTOkenGet(Request["code"],_userDomain);
if (oLinkedin.Token.Length > 0) {
_linkedinToken = oLinkedin.Token;
//now cache token using the entire _statestring and user id (removed for brevity)
}
You not allowed to do that.
Refer to the doc: https://developer.linkedin.com/docs/oauth2
Please note that:
We strongly recommend using HTTPS whenever possible
URLs must be absolute (e.g. "https://example.com/auth/callback", not "/auth/callback")
URL arguments are ignored (i.e. https://example.com/?id=1 is the same as https://example.com/)
URLs cannot include #'s (i.e. "https://example.com/auth/callback#linkedin" is invalid)
I'm using the below line:
commonService.FindAll(new Intuit.Ipp.Data.Customer(), currentPage, itemListPageSize).ToList();
When returning multiple pages the paging isn't returning the right rows on page if there are sub-customers. To reproduce, just create several customers and retrieve the second page like:
commonService.FindAll(new Intuit.Ipp.Data.Customer(), 2, itemListPageSize).ToList();
When it retrieves page 2, the first page's data is returned.
Am I doing something wrong?
FindAll with paging actually uses query endpoint.
Please mention if you are trying this call against QBD/QBO.
Can you please capture the raw request and response of the above call and share in this post.
(for that you can enable logger as mentioned in the following docs, or you can configure your app with any http snooper like Fiddler.)
https://developer.intuit.com/docs/0025_quickbooksapi/0055_devkits/0150_ipp_.net_devkit_3.0/logging
You can try this call directly using ApiExplorer. Please verify if you are getting the same result.

Let's say I have two controller methods: Users.preInsert and Users.insert. The preInsert method is the one used to display the user entry form (GET), while the insert method is responsible for the actual insertion (POST) or calling the 'insert' service.
This is how the routes looks like:
GET /users/add controllers.Users.preInsert(...)
POST /users/add controllers.Users.insert(...)
So how do I redirect a request (POST to GET) without losing the parameters like error messages returned from the insert service and the values inputed by the client so that they can be accessed and displayed in the entry form. The parameters may involve some complex objects. I have implemented it using the Caching API but I would like to know if there are any better ways of doing it.
That's the exact purpose of the Form objects (http://www.playframework.com/documentation/2.1.1/ScalaForms).
And I think there is a an error in your routes, it could look like:
GET /users/add controllers.Users.preInsert(...)
POST /users/add controllers.Users.insert(...)
You should definitively take a look at the form sample.
You don't need to redirect it back to the preInsert action, instead at the beginning of the insert check if form has errors and it it has display your view containing form (the same which you used in preInsert). It's described in the doc mentioned by nico_ekito in section Handling binding failure
