I'm working with Restless and as stated in the documentation, returning Model.objects.all() produces something like this:
{
"objects": [
{
"id": 1,
"title": "First Post!",
"author": "daniel",
"body": "This is the very first post on my shiny-new blog platform...",
"posted_on": "2014-01-12T15:23:46",
},
{
# More here...
}
]
}
This works fine. However, I don't want the "objects" wrapper to be here. My front-end code expects an array.
Is there any way of telling Restless not to wrap the array?
You can do this by overriding method Resource.wrap_list_response(). Default implementation just wraps data in a dictionary (within the objects key), you can modify this to return data unchanged.

The following text is a bit of std::string text that is generated by another app (I do not have control of what the app sends me). I have tried for days to get this converted into a QJsonArray and cannot figure this out. I am using C++ within QT. Does anyone have a bit of direction or sample C++ code that could solve this?
{
"saved_mik_yous": {
"2120ce2d-a5b1-49b8-8384-3781b7b2d73b": {
"name": null,

},

}
All you have to do is this:
QJsonDocument doc = QJsonDocument::fromJson(QByteArray::fromStdString(str));
Then, you can access the values for the keys for example as:
doc["saved_mik_yous"]
And so on.
Mind you, the json you are showing seems to be an object rather than an array since it contains key-value pairs rather than a list of elements inside square brackets. So, whilst it does not matter when you are converting the std::string into a QJsonDocument, you need to access the values by keys rather than indices.
If you are getting dynamic json which can be either an array or object, you can always check for the type with isArray() or isObject() to convert it to the right type.

My aim is to automatically set the class name within the context of the snippet being inserted. VSCode does not natively support class or method names, but it does support the file name.
My file names closely mimic the class name:
foo-bar.ts for class FooBar.
Here is my current code snippet wherein I can transform "foo-bar" to "Foo-bar" using the native "capitalize" grammar provided by VSCode.
TM_FILENAME_BASE is a native variable which extracts the filename without the extension:
"My Snippet": {
"scope": "typescript",
"prefix": "snippet",
"body": [
"${1}() {",
"\treturn this.get(${TM_FILENAME_BASE/(.*)/${1:/capitalize}/}.FIELD.${3});",
"}",
"",
"$0"
],
"description": "Creates a function wrapper for a model's attribute."
}
I'd like to transform "foo-bar" to "FooBar".
Try this:
"My Snippet": {
"scope": "typescript",
"prefix": "snippet",
"body": [
"${1}() {",
// "\treturn this.get(${TM_FILENAME_BASE/([a-z]*)-*([a-z]*)/${1:/capitalize}${2:/capitalize}/g}.FIELD.${3});",
"\treturn this.get(${TM_FILENAME_BASE/(.*)/${1:/pascalcase}/g}.FIELD.${3});",
"}",
"",
"$0"
],
"description": "Creates a function wrapper for a model's attribute."
}
EDIT : In October, 2018 the \pascalcase transform was added to vscode - see
commit, but not yet added to the documentation (as of the date of this edit). I have added the much simpler transform above which accomplishes the PascalCase transform.
Demo added, uses the clipboard after the first filename case (test-bed-snippets.xxx) just to make the various possibilities easy to demonstrate.

Thought it might be useful to supplement Mark's excellent answer with another example.
In my case, I wanted to take a name - as selected text - and convert it to Swift code that would instantiate a new class passing in variables name and email address.
So for example I select John Smith as first name, last name and convert to:
let johnSmith = User(name: "John Smith", email: "john.smith#foorbar.com")
Code snippet for this would be as follows:
"User": {
"prefix": "u",
"body": [
"\tlet ${TM_SELECTED_TEXT/([a-zA-Z]*) *([a-zA-Z]*)/${1:/downcase}$2/} = User(name: \"${TM_SELECTED_TEXT}\", email: \"${TM_SELECTED_TEXT/([a-zA-Z]*) *([a-zA-Z]*)/${1:/downcase}.${2:/downcase}/}#foobar.com\")\n",
],
"description": "Create User with name and email"
}
Is there the possibility to use an array variable inside postman?
e.g. inside the body of a request:
{
"myData" : {{arrayVariable}}
}
and inside the data file:
{
"arrayVariable": ["1", "2", "3"]
}
It's possible, you can even add your own keys
You can create a JSON body like this:
{
"myData" : [
{{arrayVariable}}
]
}
And the variable like this:
arrayVariable: "1", "2", "3"
where arrayVariable is the key and "1", "2", "3" is the value.
using variable with a same name will give you an array
Postman environment variables are meant to just save data as string, so here you are the workaround to pass array as environment variable/data file to Postman as a string like this:
{
"arrayVariable": '["1", "2", "3"]'
}
Then, add the following piece of code to parse this variable in pre-request script in Postman like this:
var x = JSON.parse(postman.getEnvironmentVariable("arrayVariable"));
postman.setEnvironmentVariable("arrayVariable", x);
Please create your body request like below
{
"myData" : ["{{arrayVariable}}"]
}
and there is no change required for data file.you can use as it is.
{
"arrayVariable": ["1", "2", "3"]
}
It will work definatly.
The only solution worked for me was something like the answer MickJagger provided, but I think it needs some clarifications.
The JSON data file should be something like this:
[
{
"anArray": "1, \"2\", 3.0, \"Foo\", false"
}
]
which it's value is a string, escaping the quotations for string elements.
(Note that this example differs from example provided by original question, to cover more use cases.)
The variables is as MickJagger said:
{
"value": [{{anArray}}]
}
Maybe other solutions works on previous postman versions, but this solution is tested on postman's latest version (by the time of publishing this answer), i.e. v7.34.0 .
all new jsfiddle: http://jsfiddle.net/vJxvc/2/
Currently, i query an api that will return JSON like this. The API cannot be changed for now, which is why I need to work around that.
[
{"timestamp":1406111961, "values":[1236.181, 1157.695, 698.231]},
{"timestamp":1406111970, "values":[1273.455, 1153.577, 693.591]}
]
(could be a lot more lines, of course)
As you can see, each line has a timestamp and then an array of values. My problem is, that i would actually like to transpose that. Looking at the first line alone:
{"timestamp":1406111961, "values":[1236.181, 1157.695, 698.231]}
It contains a few measurements taken at the same time. This would need to become this in my ember project:
{
"sensor_id": 1, // can be derived from the array index
"timestamp": 1406111961,
"value": 1236.181
},
{
"sensor_id": 2,
"timestamp": 1406111961,
"value": 1157.695
},
{
"sensor_id": 3,
"timestamp": 1406111961,
"value": 698.231
}
And those values would have to be pushed into the respective sensor models.
The transformation itself is trivial, but i have no idea where i would put it in ember and how i could alter many ember models at the same time.
you could make your model an array and override the normalize method on your adapter. The normalize method is where you do the transformation, and since your json is an array, an Ember.Array as a model would work.
I am not a ember pro but looking at the manual I would think of something like this:
a = [
{"timestamp":1406111961, "values":[1236.181, 1157.695, 698.231]},
{"timestamp":1406111970, "values":[1273.455, 1153.577, 693.591]}
];
b = [];
a.forEach(function(item) {
item.values.forEach(function(value, sensor_id) {
b.push({
sensor_id: sensor_id,
timestamp: item.timestamp,
value: value
});
});
});
console.log(b);

Update
Just saw your jsfiddle... You can geht the store like this: How to get Ember Data's "store" from anywhere in the application so that I can do store.find()?
I'm trying to load in around 30k xml files from clinicaltrials.gov into a mySQL database, and the way I am handling multiple locations, keywords, etc. are in a separate model using ManyToManyFields.
The best way I've figured out is to read the data in using a fixture. So my question is, how do I handle the fields where the data is a pointer to another model?
I unfortunately don't know enough about how ManyToMany/ForeignKeys work, to be able to answer...
Thanks for the help, sample code below: __ represent the ManyToMany fields
{
"pk": trial_id,
"model": trials.trial,
"fields": {
"trial_id": trial_id,
"brief_title": brief_title,
"official_title": official_title,
"brief_summary": brief_summary,
"detailed_Description": detailed_description,
"overall_status": overall_status,
"phase": phase,
"enrollment": enrollment,
"study_type": study_type,
"condition": _______________,
"elligibility": elligibility,
"Criteria": ______________,
"overall_contact": _______________,
"location": ___________,
"lastchanged_date": lastchanged_date,
"firstreceived_date": firstreceived_date,
"keyword": __________,
"condition_mesh": condition_mesh,
}
}
A foreign key is simple the pk of the object you are linking to, a manytomanyfield uses a list of pk's. so
[
{
"pk":1,
"model":farm.fruit,
"fields":{
"name" : "Apple",
"color" : "Green",
}
},
{
"pk":2,
"model":farm.fruit,
"fields":{
"name" : "Orange",
"color" : "Orange",
}
},
{
"pk":3,
"model":person.farmer,
"fields":{
"name":"Bill",
"favorite":1,
"likes":[1,2],
}
}
]
You will need to probably write a conversion script to get this done. Fixtures can be very flimsy; it's difficult to get the working so experiment with a subset before you spend a lot of time converting the 30k records (only to find they might not import)
