Daniel, muchas gracias por contestar y tan rápido. Pues puede ser la solución, he hecho el cambio y sigue sin pintarme los puntos -> data_ <- toJSONArray(data_, json = F) map$geoJson( # leafletR::toGeoJSON(data_, # # lat.lon = c('Lat', 'Long'), # dest=output_geofile), data_, onEachFeature =

Hey there I was scratching my head over why my application breaks when I run on a local server but works on my remote server. It turns out that my local server is Rails 2.0.2 and my remote server is 1.2.3 and I expect the tag "attributes" to be passed with a json stream, before parsing. Unfortunately, this was dropped in 2.0.2. Is there any documentation on this? Any way to get it back?

Hola, Ando un poco desesperado con los mapas interactivos de Rcharts <https://github.com/ramnathv/rCharts>+Leaflet. Estoy intentando pintar en un mapa las cámaras de tráfico de madrid, y las estaciones de calidad del aire, simplemente donde están, es decir, aun no estoy recogiendo los datos de medida.

Hello.. I am playing around on a pilot project with this wonderful Rails plugin.... thanks for sharing it w us ! I read in a post , in reply to this subject yjat : Events are possible. Either through the @map.record_init "azeazeae" (for arbitrary events like domlistener) or through the @map.event_init(@map,:click,"function(){alert(''HOYOYO'');}"). The

I tried to implement the "Rendering JSON in actions" example from http://wiki.rubyonrails.com/rails/pages/HowtoGenerateJSON : @headers["Content-Type"] = "text/plain; charset=utf-8" data = { :foo => ''bar'', :etc => ''rez'' } render :text => data.to_json When I try to decode this in javascript with

I installed the JSON gem because I wanted the JSON parser. Before installing the JSON gem, overloading worked fine. Before I remove it, I''d like to see if anyone has an idea of what is going on. It''s the only JSON parser I''m aware of, so it would be a bummer if it didn''t work. After installing, if I overload the to_json method in the class, it gives me the

Hi, I am trying to convert a hash to JSON using ActiveSupports built in .to_json. I am doing similar to the example below but are there certain strings that could go in place of ''bar'' or ''rez'' that will break the to_json method? I am using a very long string from rjs output in place of ''bar''. Perhaps .to_json is not ready yet? Thanks, Peter

The way Rails handles root nodes in JSON and XML serialization is inconsistent. This has been discussed before: https://rails.lighthouseapp.com/projects/8994/tickets/2584-232-activeresource-json-doesnt-send-parameters-with-root-node This seems mostly taken care of with ActiveModel::Base.include_root_in_json, especially if/when it ends up in ActiveResource. However, there is also the issue of how

I am using Rails 2.0.2 and trying to use to_json to generate json. I notice several problems. 1) datetime field such as created_at mapped to "created_at": {} 2) :except does not work, @post.to_json(:except => [:created_at, :updated_at] still gives me "created_at": {}, "update_at": {} 3) problem with escaped char mapping: ''<'' mapped to

Hi all, I''m working on a Backbone.js single page app with Rails 3.1, and in an attempt to save on HTTP requests, I want to embed initial data set in a HTML document that is sent back to the browser after successful login. I was thinking I can simply convert my ruby object to JSON, then HTML escape resulting string of JSON, and then use that as a value for JavaScript variable. Something

I''d really like to see just 2 more functional changes to the JSON serialization/encoding before we get to Rails 2.0. First, and I think this is really crucial because without it all the efforts to output JSON from ActiveRecord objects would have been half in vain, is to allow us to do this in controllers: @authors = Author.find(:all) render :json => @authors.to_json(:only =>

Hello R-helpers, I am trying to search for string that includes the caret symbol, using the following code: grepl("latitude^2",temp) And R doesn't like that. It gives me: > temp<-c("latitude^2","latitude and latitude^2","longitude^2","longitude and longitude^2") > temp [1] "latitude^2" "latitude and

Dear all, I have been trying to convert coordinates from longitude/latitude to utm but I got an error. As soon as the longitude coordinate is greater than 90, I get the folloowing error message: "error in pj_transform: latitude or longitude exceeded limits" Here is what I did: SP<-SpatialPoints(cbind(126.59,-14.30),proj4string=CRS("+proj=longlat"))

I have a dataset showing points, with a category for each point and its location. I simply want to display my points, in a way that users can toggle the points on and off by category. Where I have two objects in the same category I'd like to display them nudged to appear as two distinct, but very close points. I have made reproduceable example (the places are not real), which is loosely

Hi list, I have a problem to solve which I believe I shoudl use the convolve to solve it, but I could not figure out how to do it. I got mydata, which is a dataframe which has 7 locations, each location has a longitude,latitude and a value. considering a step of 0.5 degree for longitudes and latitudes, I got 15 points for longitude and 15 points for latitude. Then I created a grid, mygrid, which

Hi, my mapstraction onclick event handlers always yielded javascript errors in Virtual Earth maps ("e.view is undefined"). I''m using version 6 of mapcontrol.ashx. After consulting Virtual Earth documentation, I came up with a solution. Here is my patch (based on rev 212) > var that = this; 360c361,368 < me.clickHandler(e.view.LatLong.Latitude,

Someone asked me in IRC if javascript can access ActiveRecord properties. At first, this seemed like a silly request. But then I remember JSON and thought, why can''t you? I implemented a quick ActiveRecord -> JSON converter using the ruby-json gem. http://rafb.net/paste/results/Yixi5I21.html One problem was that I have to call .to_s to convert everything to a format for JSON.

Hey, I''ve tried every trick I can find, yet I''m still unable to get the json gem and ActiveSupport to play nice. No matter in which order I load json and active support, I still end up with: NoMethodError: undefined method `[]'' for #<JSON::Ext::Generator::State:0x104b7fac0> I''m trying to use the JSON object directly, *not* as a ActiveSupport backend:
