Re: Rails to_json or as_json?

pseudo_rails — Wed, 14 Dec 2011 05:36:51 -0000

Oops, I had a typo in my MyController pseudo code.

It should be this:

class MyController < ApplicationControllerrespond_to :jsondef show@user = User.find(params[:id])
respond_with(@user , :include => {:addresses => {:include => :email}})
end

Which I want to refactor with something like this in the model:
def as_json(options={})super(:only => [:email, :avatar], :include =>[:addresses => {:include => :email}])end

But I get an
undefined method `macro' for nil:NilClass

Given the following example from your blog post:

def as_json(options={})
super(:only => [:email, :avatar], :include =>[:addresses])
end

when overriding the as_json method, if I want to include nested child nodes, how would I go about doing so? I essentially want to refactor the respond_with usage in my controller by just overriding the as_json method in the model.

class MyController < ApplicationController
respond_to :json
def show
@user = User.find(params[:id])
respond_with(@tag, :include => {:addresses => {:include => :email}})
end

Great detailed post, Jonathan. I wish I'd had your reserved nature at Start Up Weekend earlier this year. Sounds like you picked a fabulous team and I'm sure they were happy to have you. Congrats on the win & making through that learning curve!

Re: Wrapping a div around will_paginate page_entries_info

That initializer works for Rails 2.3.x - since you're on Rails 3, try a newer pagination gem: https://github.com/amatsuda/ka...

Hmm.. I dropped that into config/initializers/will_paginate.rb and I now get "undefined method `page_entries_info' for module `WillPaginate::ViewHelpers'" when I attempt to start rails. So, it seems to be attempting to process this file before it loads the will_paginate gem (Rails 3.0.7).

Check out http://engineering.gomiso.com/... We agree 100% and found a better way. to_json / as_json is rarely the right way to go about this.

I experience a huge performance hit, if I override as_json in the model rather than using it directly. Can anybody confirm this? If so, what coul be the reason?
Thanks

Thanks for the post, Jonathan. I wish I had been able to go.

I really appreciate the links to the slides--it makes it so much faster to get caught up on what happened at the conference.

Hi Jonathan,

Great blog post. I am not able to use as_json with :include very well. I have posted a questions at http://stackoverflow.com/quest... (please ignore the comment there about acts_as_api).

Would appreciate it if you can take a look at it.

Thanks,

As mentioned above, "Watch out for a bug in Rails 3.0". I haven't found it reported yet.

Can you confirm this works with rails3?

Good description. Watch out for a bug in Rails 3.0 tho. Calling super from as_json won't work. Read more http://blog.ternarylabs.com/20...

Tony Amoyal — Fri, 20 Aug 2010 10:57:53 -0000

How would you make this better? If it's truly going to be a view than you will return everything from as_json and create the object you need in the client side code. So then you can just make as_json skip any attributes you will never need. Do you have a better way to do this?

Even better, this guy has bundled it up into a Rails plugin and has made passing options to JSLint possible through a .yml configuration file! http://lunarlogicpolska.com/bl...

Lawrence Pit — Mon, 14 Jun 2010 22:16:24 -0000

What as I don't like about this is that as_json to me is like a view, and should not belong in my model. The options hash only leads to more unnecessary if-then-else branches.

Re: Rails to_json or as_json?

jjulian — Fri, 11 Jun 2010 17:02:54 -0000

Try @people.first.as_json. The options passed to as_json only take :only and :except.
