How to Include Associations in #as_json
Hi,
Does anyone know how to include nested associations when overriding a
model''s #as_json method?
Below is my attempt to include direct and nested associations.
NOTE: "office" is a direct association, "company" is nested association
via "office". I''d like both included in the generated json output.
def as_json(options={})
super(:include...

as_json and self-referential associations
Hi,
I''m using the new(?) as_json methods within a rest api I am working
on.
However I am not sure how you are supposed to, or whether it is
designed to handle multiple variations of association inclusion.
For example I have a model using acts_as_tree, so that each instance
has children and a parent:
class CatalogueCategory <...

Correct way to exclude attributes from json serialization
..._id: 54857324987546, // internal mongoid document id
report_field_a: 1,
report_field_b: 2,
etc
}
I would like to strip this when serializing the report to json, and I
would also like any embedded documents to have their _id properties
excluded too. I have searched for info on as_json, to_json etc but I''m
not sure which is the best practice approach. The closest I can get
is:
class Report
include Mongoid::Document
...
def as_json(options = {})
serializable_hash({ :except => :_id }.merge(options))
end
end
...and then I need to copy that same as_json defi...

Rails - JSON object with an array?
Hello, I''m able to create and send a JSON object like so:
@mylist << {
:id => item.id,
:name => name.id
}
render :json => { :result => ''success'', :mylist => @mylist }
That works great. Problem I''m having now is that I need to include
users which can be 1 or users per item.

active_model_serializers, more than one level deep of associations, specifying serializers per association
...onsiblity other than the existing
circular reference checking that happens already (does it only just check
for back reference as I remember seeing vs. keeping track of previously
output object_ids? I had to do the latter to avoid them in a previous
version of restful_json when I was mutilating as_json)?
(Apologies for my continued ineptitude.)

additional model attributes
Hi,
i have a "place" model with 2 columns (id, name).
I''m calling an external api which gives me data to create a new place
object.
I would like to add the address from the external place to the place
object and render it as a json result, without storing it in the
database.
i don''t get any errors, but the address never shows up within the json
output. i''ve

to_json performance
Originally posted on github, reported to the right place.
I would like to open a discussion about how `to_json` and `as_json`
operates in Rails from a performance standpoint.
I''m using Rails 3.2 but this issue applies to almost all versions of
Rails.
Our use case presents the challenge in sending out potentially large
JSON (or XML, but we''ll focus on JSON rendering here) bodies as a
response of a API...

JSON PUT/POST/UPDATE
Hey all... I''m building a RESTful JSON API and I find myself writing
this:
JSON.parse(request.body.read)
...over and over in every controller action that accepts JSON in the
request body (which is a lot of actions).
Does rails have a better built-in way to keep the code more DRY? Or
should I solve that somehow myself?
Thanks,

"best practices" for Rails serving RESTful JSON services for use by AngularJS, Ember.js, etc.
...e associations if you told it to allow that, etc. In other
words, accepts_nested_attributes_for is inadequate.
What we''ve tried and looked into as a DRY way to using Rails in large part
as JSON service provider:
* RABL: provides an way to do json views (to replace sending options into
as_json/to_json) does not handle incoming JSON to be persisted in a similar
way.
* ActiveModel::Serializers available now and coming in Rails 4 - similar to
RABL in that it does not map incoming JSON to be persisted.
* strong_parameters available now and coming in Rails 4 - keeps you from
being able to...
