Hi all,
I would like to expose a problem that I'm facing sending complex objects as
parameters to ngResource. I'm trying to do the following query with
ngResource:
var Customer = $resource('http://localhost:3000/api/users');
var params =
{
conditions: {
age: { "$gt": 30 }
},
options: {
limit: 2
}
};
Customer.query(params,
function(data) {
$scope.users = data;
}
);
And in the browser console I get the following error:
GET
http://localhost:3000/api/users?conditions=%7B%22age%22:%7B%7D%7D&options=%7B%22limit%22:2%7D
400 (Bad Request)
As you can see, the parameters that I'm sending are being escaped, and this
is causing a bad request.
If I try to do the following request through $http I don't get any problem:
$http.get('http://localhost:3000/api/users?conditions={"age":{"$gt":30}}&options={"limit":2}').success(function(data)
{
$scope.users = data;
});
So, I have to questions:
1) Is there anyway to avoid the problem that I'm facing when sending
complex parameters to ngResource.
2) Do you think that is a good practice sending parameters as I'm doing in
my previous examples? Or do you think that would be better in this way:
http://localhost:3000/api/users?age-gt=30&limit=2 ? Undoubtedly, this last
way is much cleaner, but I think that in my previous examples I have a lot
of flexibility, because this is the way that MongoDB uses to query its
collections, and as I have a MongoDB in my back-end then I can send
directly the parameters to the MongoDB query.
I didn't like brackets in the URL, but I have seen that parse.com uses a
similar syntax to query its data:
curl -X GET \
-H "X-Parse-Application-Id: ${APPLICATION_ID}" \
-H "X-Parse-REST-API-Key: ${REST_API_KEY}" \
-G \
--data-urlencode 'where={"score":{"$gte":1000,"$lte":3000}}' \
https://api.parse.com/1/classes/GameScore
I would appreciate a lot your comments regarding these two questions.
Thank you very much!!
