I'm tring my hand in Meteor - so far, I like it :-)
However, I am trying to store a JSON object directly into miniMongo, but not getting anywhere - while I thought that was the purpose :-)
testVar = {"test":"this is from the object"}
QStore.update(
{"_id" : QT._id},
{
$set: {
"tCode" : testVar,
"name" : "verion 6"
}
}
)
in the schema of the QStore, tCode is defined as {object} which I thought would be right... where am I wrong? :-)

Paul
Assuming you're using aldeed:simple-schema and everything else is okay (which is tough to tell with only the code snippet above), it's most likely you're missing the blackbox flag in your schema definition:
blackbox
If you have a key with type Object, the properties of the object will be validated as well, so you must define all allowed properties in the schema. If this is not possible or you don't care to validate the object's properties, use the blackbox: true option to skip validation for everything within the object.

I am working with JSON structured data in ADF and trying to implement an IF condition where, if a property is defined in JSON, I will execute one path, another if not defined.
For example, consider the JSON data:
{
"name" : "sh"
"RareProperty" : "rarevalue"
}
RareProperty may or may not exist depending on scenario.
If I try to reference RareProperty in the If Condition block, I get an error saying property RareProperty not defined, which is understandable as the property isn't actually defined in the scenario.
I am looking for a way to check if a property is defined without getting any error.
I think you can use the ? something like
#{body('yourresponse')?['RareProperty']}
I'm using the TJsonDataObjects Delphi component (https://github.com/ahausladen/JsonDataObjects). I am using it as the data store for what is is displayed in a editable TreeView. In the treeview I store the "path" using a JsonPath string. When the user modifies the values in the Treeview, the path property allows me locate the record by path and modify it via the component path property.
My issue is when a user wants to delete a record, I need to remove it from the JSON file. It does note seem like there is a simple way to do this via its "path. I expect I could trim off the item from the path to gets it parent and then delete it by "name" or "index" if an array. I was hoping there might just be an easier way before I start to code this up.
On a similar node, I didn't find any way to extract the text path of a given item. While it can modify or locate a node by path, there does not seem to be a way to get the actual path so I'm doing that manually as I parse the JSON file (yuck). Anyone have a better solution?
For example, this is the path of the "value" property in the JSON below: Level1.Level2.Level3
{
"Level1": {
"Level2": {
"Level3": "value"
}
}
}
In TJsonDataObjects you can set the path with:
Json.Path['Level1.Level2.Level3'] := "value";
//or
Json['Level1']['Level2']['Level3'] := "value";
Or retrieve it with:
prop := Json.Path['Level1.Level2.Level3'];
// or
prop := Json['Level1']['Level2']['Level3'];
So if you want to remove Level3, it would be nice if there was some simple function like Json.DeletePath('Level1.Level2.Level3');. As far as I can tell, there is nothing that does this. Since this is a very complex unit, I thought someone might have an easy answer that I overlooked. I have coded a way around this (as described above).
As to the second question, while you can access a value by its path, there is no function to "return" a path from a given node. And yes, I can and do build it as I go along, it would be handy as that way it remains consistent in its format of the JsonPath.
I got an anonymous array which I want to deserialize, here the example of the first array object
[
{ "time":"08:55:54",
"date":"2016-05-27",
"timestamp":1464332154807,
"level":3,
"message":"registerResourcePath ('', '/sap/bc/ui5_ui5/ui2/ushell/resources/')",
"details":"","component":"sap.ui.ModuleSystem"},
{"time":"08:55:54","date":"2016-05-27","timestamp":1464332154808,"level":3,"message":"URL prefixes set to:","details":"","component":"sap.ui.ModuleSystem"},
{"time":"08:55:54","date":"2016-05-27","timestamp":1464332154808,"level":3,"message":" (default) : /sap/bc/ui5_ui5/ui2/ushell/resources/","details":"","component":"sap.ui.ModuleSystem"}
]
I tried deserializing using CL_TREX_JSON_SERIALIZER, but it is corrupt and does not work with my JSON, here is why
Then I tried /UI2/CL_JSON, but it needs a "structure" that perfectly fits the object given by the JSON Object. "Structure" means in my case an internal table of objects with the attributes time, date, timestamp, level, messageanddetails. And there was the problem: it does not properly handle references and uses class description to describe the field assigned to the field-symbol. Since I can not have a list of objects but only a list of references to objects that solution also doesn't works.
As a third attempt I tried with the CALL TRANSFORMATION as described by Horst Keller, but with this method I was not able to read in an anonymous array, and here is why
My major points:
I do not want to change the JSON, since that is what I get from sap.ui.log
I prefere to use built-in functionality and not a thirdparty framework
Your problem comes out not from the anonymity of array, but from the awkwardness of SAP JSON (De)serializer, which doesn't respect double quotes, which enclose JSON attributes. The issue is thoroughly described in this answer.
If you don't want to change your JSON on-the-fly, the only way you have is to change CL_TREX_JSON_DESERIALIZER class like this.
/UI5/CL_JSON_PARSER parses JSONs with unknown format.
Note that it's got "for internal use" written on it so many times that you probably should take it seriously and clone its code to fixate it.
For a sample JSON data which looks like this -
{
"children":{
"Alice":{...},
"Jamie":{...},
"Bob":{...}
// Any new child with a given unique name will be added to this object
},
childrenOrder:["Alice", "Bob", "Jamie"]
}
In the corresponding JSON Schema, I am trying to limit the valid values in "childrenOrder" array to be from the run time children keys.
I didn't see any means of referring to runtime dynamic values in the official JSON Schema documentation (http://json-schema.org/documentation.html).
Is this even possible at the moment?
For the sake of brevity I omitted JSON Schema code. I can add it if folks think it is needed to address the question.
Thanks in advance.
No it is not possible using the current JSON Schema specification. However, there is a proposal for the next version of JSON Schema that could change that.

I'm trying to parse a grails parameter map to a Json String, and then back to a parameter map. (For saving html form entries with constraint-violations)
Everything is fine as long as there is no hasMany relationship in the parameter-map.
I'm using
fc.parameter = params as JSON
to save the params as JSON String.
Later I'm trying to rebuild the parameter map and create a new Domain-Object with it:
new Foo(JSON.parse(fc.parameter))
Everything is fine using only 1:1 relationships (states).
[states:2, listSize:50, name:TestFilter]
But when I try to rebuild a params-map with multi-select values (states)
[states:[1,2], listSize:50, name:TestFilter]
I'm getting this IllegalStateException:
Failed to convert property value of type org.codehaus.groovy.grails.web.json.JSONArray to required type java.util.Set for property states; nested exception is java.lang.IllegalStateException: Cannot convert value of type [java.lang.String] to required type [de.gotosec.approve.State] for property states[0]: no matching editors or conversion strategy found
I tried to use this, but without success:
JSON.use("deep") {
new Foo(JSON.parse(fc.parameter))
}
You can use JsonSlurper instead of the converters.JSON of grails, it maps JSON objects to Groovy Maps. I think this link also might help you.
Edit: Now, if the problem is binding the params map to your domain, you should try using bindData() method, like:
bindData(foo, params)
Note that this straightforward use is only if you're calling bindData inside a controller.
What seems to be happening in your case is that Grails is trying to bind a concrete type of List (ArrayList in the case of JsonSlurper and JSONArray in the case of converters.JSON) into a Set of properties (which is the default data structure for one-to-many associations). I would have to take a look at your code to confirm that. But, as you did substitute states: [1,2] for a method of your app, try another test to confirm this hypothesis. Change:
states:[1,2]
for
states:[1,2] as Set
If this is really the problem and not even bindData() works, take a look at this for a harder way to make it work using object marshalling and converters.JSON. I don't know if it's practical for you to use it in your project, but it sure works nicely ;)
