I try to change some field when I create/update data whith loopback. The POST method works, but now the PUT method is down.
my category.json:
{
"name": "category",
"base": "PersistedModel",
"properties": {
"name": {
"type": "string",
"required": true
},
"image": {
"type": "string",
"required": true
}
},
"validations": [],
"relations": {},
"acls": [],
"methods": []
}
and the category.js for define methods:
module.exports = function(categorie) {
categorie.observe('before save', function(ctx, next){
ctx.instance.name = ctx.instance.name.toUpperCase().trim();
ctx.instance.image = ctx.instance.image.trim();
ctx.instance.image = ctx.instance.image.charAt(0).toUpperCase() + ctx.instance.image.slice(1);
next();
});
};
I receive this error message:
{
"error": {
"name": "TypeError",
"status": 500,
"message": "Cannot read property 'name' of undefined",
"stack": "TypeError: Cannot read property 'name' of undefined\n at /home/pitt/warm-wildwood-2324/common/models/category.js:5:35\n at notifySingleObserver (/home/pitt/warm-wildwood-2324/node_modules/loopback-datasource-juggler/lib/model.js:600:22)\n (...) at Function.ModelBaseClass.notifyObserversOf (/home/pitt/warm-wildwood-2324/node_modules/loopback-datasource-juggler/lib/model.js:593:8)"
}
}
ctx.instance is not undefined while partial update of possibly multiple models, instead access ctx.data property.

I'm not very strong in swagger 2.0, could you please help me? I'm trying to describe body parameters, but got an error. Here is my swagger.json file:
{
"swagger": "2.0",
"info": {
"title": "Simple API overview",
"version": "v2"
},
"host": "localhost:4000",
"basePath": "/",
"paths": {
"/user/register": {
"post": {
"operationId": "register",
"summary": "User registration",
"parameters": [{
"in": "body",
"name": "role",
"required": true,
"schema": {
"type": "integer",
"example": 1
}
}]
}
}
}
}
When I try to run it, I got an error:
Error: Expected `string` for value, got `1`
If I remove example field, I got this in Example Value section:
{}
Looks like the type definition is incorrect, but I couldn't figure out what's the difference between my code and examples from swagger docs.
Any help is appreciated.
Thanks.
I found the reason: there should be consumes field defined as text/plain. By default it is application/json.
The full code:
{
"swagger": "2.0",
"info": {
"title": "Simple API overview",
"version": "v2"
},
"host": "localhost:4000",
"basePath": "/",
"paths": {
"/user/register": {
"post": {
"operationId": "register",
"summary": "User registration",
"consumes": ["text/plain"],
"parameters": [{
"in": "body",
"name": "role",
"required": true,
"schema": {
"type": "integer",
"example": 1
}
}]
}
}
}
}
One way to get around this error is to change type from integer to string.
"parameters": [{
"in": "body",
"name": "role",
"required": true,
"schema": {
"type": "string",
"example": "1"
}
}]
I am looking into what is wrong with my schema. I'm attempting to insert an entry into my collection and I have gotten a slew of errors as I've changed things around but this seems to be the closest I have gotten to successfully inserting a document. I am using the mongodb-stitch-browser-sdk in a React Ionic project and I have a valid user logged in.
I am using the StitchUser.id which is a string as my owner_id (matches the id of my valid user in users collection).
Here is my schema followed by the error in Stitch logs. I was simply trying to insert a document to my Goals table. Also, there are no filters on this collection and there is only one role with the following rule.
{
"owner_id": "%%user.id"
}
This gives the user read and write permissions on the collection's that they created.
{
"bsonType": "object",
"required": [
"goalTitle",
"startDate",
"endDate",
"owner_id"
],
"properties": {
"_id": {
"bsonType": "objectId"
},
"owner_id": {
"bsonType": "string",
"validate": {
"%or": [
{
"%%prevRoot.owner_id": {
"%exists": false
}
},
{
"%%prevRoot.owner_id": "%%this"
}
]
}
},
"goalTitle": {
"bsonType": "string",
"minLength": {
"$numberInt": "1"
},
"maxLength": {
"$numberInt": "30"
}
},
"goalDescription": {
"bsonType": "string",
"minLength": {

},
"maxLength": {
"$numberInt": "600"
}
},
"startDate": {
"bsonType": "string"
},
"endDate": {
"bsonType": "string"
}
}
}
Error:
role "owner" in "todo_list.Goals" does not have insert permission for document with _id: ObjectID("5e6aa8d11d233536e3ea8604"): could not validate document:

}
],

}
I've created another collection with no schema and the same rule checking for owner_id and documents in that collection are able to be inserted just fine. I'd have to imagine it is a schema error.
I'm having difficulty accessing data in a collection, via PowerApps.
I create the collection with this:
Collect(coll15,mt.GetAnswers("3b....da","application/json",{question:"eco"}))
Using Developer Tools -> Network tab -> Response body - the following JSON data is returned:
{
"answers": [
{
"answer": "This is the answer",
"questions": [
"Private vehicle eco renewal"
],
"score": 82.901087775826454
}
]
}
The collection is created.
I then add a gallery control to my page - however the only options I have to bind to the labels are: ThisItem.Value
If I try to enter ThisItem.Value.answer I get the error: Invalid use of '.'
If I enter ThisItem.answers.answer I get the error: Invalid name
This is the swagger file:

},

Is there any way for me to access the answer text within the collection?
Thanks for any help,

The problem is that the response type for the operation in the connector definition is string:
"responses": {
"default": {
"description": "default",
"schema": {
"type": "string"
}
}
}
But your response is an object instead. If you update your custom connector to use a typed object instead, you should be able to access the response from the operation. Something along the lines of the schema below:
"responses": {
"default": {
"description": "default",
"schema": {
"type": "object",
"properties": {
"answers": {
"type": "array",
"items": {
"type": "object",
"properties": {
"answer": {
"type": "string"
},
"questions": {
"type": "array",
"items": {
"type": "string"
}
},
"score": {
"type": "number",
"format": "float"
}
}
}
}
}
}
}
},
Notice that in the portal (web.powerapps.com), if you go to your custom connector definition, and select "Edit", you can go to the operation, and select the response you want to edit:
And then use the "Import from sample" option
With that, if you enter an example of a response from the API, it will create the schema for you (which is similar to the one I have above).
I have an internal app that uses a webhook listener and some scripting to manipulate the input data. I'm posting this to it:
curl -X POST -d '{
"assignment_id": 12345,
"updated_custom_fields": [{
"name": "RNVIDAYEBB",
"value": "updated!"
},
{
"name": "QUFTXSIBYA",
"value": "and me too"
}
],
"custom_fields": [{
"id": 981,
"name": "RDEXDPVKRD",
"fields": [
{
"id": 4096,
"name": "RNVIDAYEBB",
"default": "EDJEAJICYW",
"required": true,
"value": "Blah"
},
{
"id": 4097,
"name": "QUFTXSIBYA",
"default": "",
"required": true,
"value": ""
}]
}]
}' "https://hooks.zapier.com/hooks/catch/......"
My script is as follows:
update_custom_fields_by_name_pre_write: function(bundle) {
var updatedFields = _.map(bundle.request.data.custom_fields, function(group) {
return _.map(group.fields, function(field) {
return _.extend(field, _.findWhere(bundle.request.data.updated_custom_fields, { name: field.name} ));
});
});
bundle.request.data = updatedFields;
return bundle.request;
}
I know that the merging logic is good, but it appears that the custom_fields and updated_custom_fields arrays are not present in the bundle.request.data object. Anyone know how to get access to them in the script?
It seems like you should be using update_custom_fields_by_name_catch_hook to capture the incoming static webhook data (instead of _pre_write). If you use that, you can capture the data within bundle.cleaned_request.custom_fields and bundle.cleaned_request.updated_custom_fields.
Inside the Swagger API Documentation there is inside the json beside the apis array a model object entry but no documentation about it. How can I use this "models" part?
{
apiVersion: "0.2",
swaggerVersion: "1.1",
basePath: "http://petstore.swagger.wordnik.com/api",
resourcePath: "/pet.{format}"
...
apis: [...]
models: {...}
}
Models are nothing but like your POJO classes in java which have variables and properties. In models section you can define your own custom class and you can refer it as data type.
If you see below
{
"path": "/pet.{format}",
"description": "Operations about pets",
"operations": [
{
"httpMethod": "POST",
"summary": "Add a new pet to the store",
"responseClass": "void",
"nickname": "addPet",
"parameters": [
{
"description": "Pet object that needs to be added to the store",
"paramType": "body",
"required": true,
"allowMultiple": false,
"dataType": "Pet"
}
],
"errorResponses": [
{
"code": 405,
"reason": "Invalid input"
}
]
}
Here in parameter section it have one parameter who's dataType is Pet and pet is defined in models as below
{
"models": {
"Pet": {
"id": "Pet",
"properties": {
"id": {
"type": "long"
},
"status": {
"allowableValues": {
"valueType": "LIST",
"values": [
"available",
"pending",
"sold"
]
},
"description": "pet status in the store",
"type": "string"
},
"name": {
"type": "string"
},
"photoUrls": {
"items": {
"type": "string"
},
"type": "Array"
}
}
}
}}
You can have nested models , for more information see Swagger PetStore example
So models are nothing but like classes.
