问题 I have objects that look like: [<ltree_val: "1", contents: "blah">, <ltree_val: "1.1", contents: "blah">, <ltree_val: "1.1.1", contents: "blah">, <ltree_val: "2", contents: "blah">, <ltree_val: "2.1", contents: "blah">] Where ltree_val determines their tree structure. I need to generate something like... [{ "data" : "1", "children" : [{ "data" : "1.1", "children" : [{ "data" : "1.1.1" }] }] }, { "data" : "2" }] Where I have children which are determined by an ltree value, which are themselves

问题 I'm trying to render a rabl view to string in a rails 3.2 rake task. I'm rendering it to string in order to send some JSON through Pusher from a background task. I've looked at various render_to_string from rake task answers but none of them seem to work. Here is what I have thus far: controller = PostsController.new av = ActionView::Base.new(MyApp::Application.config.paths['app/views'].first,{},controller) @post = post Pusher["some channel"].trigger('new_post', av.render(:template => 'posts

Spring template engine for rendering JSON

由 ＊爱你＆永不变心＊ 提交于 2019-12-07 14:33:52
问题 I come from Ruby and have just started testing Spring and find it fairly nice. However i'm used to being able to customize the rendered JSON output with libraries like rabl and it feels really wrong to expose internal models straight out into the JSON as i do now with the annotation @ResponseBody and just returning the model. Does anyone have any tips on libraries similar to rabl but for java/spring or is there an existing way to do it easily with spring without manually writing templates in

How can I pass an object to rabl views from rake task

由 巧了我就是萌 提交于 2019-12-06 12:05:00
I am trying to create a json file from a rake task using rabl. Below I have the simplified version to test with. When I view 'articles.json' or 'articles/2.json' via the url, I get the expected json response. But when I try to run it via the rake task, it always has a null value for @articles in the jsonFile created. It will render the index.json.rabl view the same number of times as @articles.count, but the values are always null. So how do I pass in the @articles object created in my rake task to Rabl.render? index.json.rabl @feedName ||= 'default' node(:rss) { partial('articles/rss),

Rails RABL respond_with error template

由 时间秒杀一切 提交于 2019-12-06 11:24:46
Using RABL in Rails 3.2.x, given the following controller action: respond_to :html, :json def create @foo = Foo.create(params[:foo]) respond_with @foo end Assuming the validation fails, how do you get respond_with to use a RABL template instead of the standard JSON hash of errors -- IE. I would like other model attributes besides the validation error message sent back along with the request. Suggestions? I found this one out the hard way. You should create a custom responder for your application controller, or at least your individual response. See Three reasons to love ActionController:
