I have the following model relationship in my LoopBack 4 application:
A Survey has 1-many relationship with Question,
Question has 1-many relationship with Option.
Am using MongoDB as the database. I am unable to figure out how to implement a PUT/PATCH REST api, that can update the entire Survey model containing the Questions and Options. I get the following exception when i try a PATCH on the sample request JSON below:
Exception: Unhandled error in PATCH /5be3e00aad0df83d10e580d1: 500
TypeError: Class constructor Question cannot be invoked without 'new'

Sample PATCH request:
[{
"title": "Some survey title 1",
"description": "Some survey title 1",
"questions": [{
"options": [{
"description": "Some option description 1",
"type": "Option"
}],
"description": "Some question description 1"
}]
}]
Have not been able to find any helpful information on this yet. Any pointers please?
Thanks in advance.

I have an endpoint URL, within Swagger I must pass certain fields to test the POST method. I was wondering if anyone had an example of how to set up a Karate test for a POST method?
Yes, there are plenty in the documentation: https://github.com/intuit/karate
If you follow the quickstart, you will get a sample project with a working POST: https://github.com/intuit/karate#quickstart
Scenario: create a user and then get it by id
* def user =
"""
{
"name": "Test User",
"username": "testuser",
"email": "test#user.com",
"address": {
"street": "Has No Name",
"suite": "Apt. 123",
"city": "Electri",
"zipcode": "54321-6789"
}
}
"""
Given url 'https://jsonplaceholder.typicode.com/users'
And request user
When method post
Then status 201
What is the proper way to identify if the author of a post is a user or a page?
v2.8/OrangeESP/feed?fields=id,from{id,name,link}
"data": [
{
"id": "118067454874491_1584993008181921",
"from": {
"id": "1112315252115029",
"name": "Clara Barranquero",
"link": "https://www.facebook.com/app_scoped_user_id/1112315252115029/"
}
},
I currently use the "from.link" for that and if it is of form
https://www.facebook.com/app_scoped_user_id// then is a User
if it's of from
https://www.facebook.com/ then it is a Page
In v2.4 I could have included from{category} in the response and if that was not empty it meant the author is a Page.
Include a field that´s only available in the Page or User table:
https://developers.facebook.com/docs/graph-api/reference/page/
https://developers.facebook.com/docs/graph-api/reference/user/
Checking for app_scoped_user_id in the link field is not a bad idea though.
I have asked some old questions previously but those were quite misleading. So I decided to delete them and creating this one.
My object has a custom property named say it is portal content. In the Facebook Graph API Explorer data related to this object shown like;
{
"created_time": "2015-11-26T08:42:26+0000",
"title": "Title",
"type": "ns:type",
"data": {
"portalcontent": "portalcontent"
},
"id": "12515125125"
},
{
"created_time": "2015-11-26T08:04:09+0000",
"title": "Title2",
"type": "ns:type",
"id": "412512512512"
},
{
"created_time": "2015-11-25T12:56:03+0000",
"title": "Title3",
"type": "ns:type",
"id": "234124124124"
}
I am trying to query this data using Facebook graph api. But can not fetch just based on the portal content custom property.
So far I tried;
appid/objects?pretty=0&type=ns:type&limit=100&portalcontent=portalcontent
to do so. But it is still fetching all objects.
PS: please pm or comment on question for why you are downvoting it. Provide what else you need that I must put on the question. Downvoting for no reason getting people annoyed.
There's currently no way to filter results other than those described on the respective endpoint's docs.

First of all, any help with this would be amazing! I am currently trying to learn Django and am also fairly new to Python. I am trying to create a simple project management web service that could communicate using JSON with another application. All it needs to do is:
Give a list of all projects.
Give a list of all tasks for each of the projects.
Allow users to submit time for a project and task.
For models I currently have a 'Project' model and 'Task' model. I have filled the database with some dummy information. My project model has variables id, name, and description. Task just has project, task_name.
My view for task 1 above is
def api(request):
projects = Project.objects.all()#.order_by('id')
projects = serializers.serialize('json', projects, indent=2)
return HttpResponse(projects, mimetype='application/json')
associated url is url(r'^api/project/$', 'project.views.api'),
However this outputs the text below when typing
http://127.0.0.1:8000/api/project/
into the browser. Is there a better way to test JSON output? I would rather it only output the 'id' and 'name'. For some reason the id doesn't even show. This is what I put for id in models id = models.AutoField(primary_key=True). It works in the interactive shell.
[
{
"pk": 1,
"model": "project.project",
"fields": {
"name": "Project One",
"description": "This is the description for project one"
}
},
{
"pk": 2,
"model": "project.project",
"fields": {
"name": "Project Two",
"description": "This is Project Two"
}
}
]
I learn by example so if someone could show me how this should be done I would be extremely grateful!
By the way for outputting the list of tasks, I was thinking the url would be something like:
http://127.0.0.1:8000/api/project/?project_name
but I'm not sure how to handle that in the view.
here I am for real update "page", add fields to status to receive the "status" of
pages, I try to add as "link" fields to receive the subscription works but I do
not receive notification when I publish a link, it's really difficult to have
correct information
{
"object": "user",
"callback_url": "http://*/fbcallback.php",
"fields": [
"feed",
"link",
"status"
],
"active": true
}
http://bugs.developers.facebook.net/show_bug.cgi?id=18048#c40
As per the documentation at https://developers.facebook.com/docs/reference/api/realtime/ :
To setup a subscription, send a POST with the following parameters
It seems like you're posting a JSON object while you should do is a normal post with these variables (as if you're doing a with action="post").
Note, by the way, that the fields parameter needs to have a CSV value, so that would be "feed,link,status", and that there's no 'active' attribute.
