问题 I'm using JBuilder as to return some JSON. I have a index.json.jbuilder that generates the data, and I need to render it to a string.

How do you increase the maximum heap size for the javac process in Borland JBuilder 2005/2006

由 ﹥＞﹥吖頭↗ 提交于 2019-12-12 18:34:08
问题 In most modern IDEs there is a parameter that you can set to ensure javac gets enough heap memory to do its compilation. For reasons that are not worth going into here, we are tied for the time being to JBuilder 2005/2006, and it appears the amount of source code has exceeded what can be handled by javac. Please keep the answer specific to JBuilder 2005/2006 javac (we cannot migrate away right now, and the Borland Make compiler does not correctly support Java 1.6) I realize how and what

由 笑着哭i 提交于 2019-12-11 15:24:28
问题 I've created GeoJSON file with Rails jBuilder and want to read it in to Leaflt. It's OK if I use it directly like so L.mapbox.featureLayer().loadURL('overview/overview_data.geojson').addTo(map) but I want to use Leaflet.timeline and work with the GeoJSON. If I put the GeoJSON in the script like so let data = {"type":"FeatureCollection","features":[{"type":"Feature","properties":{"start":1903,"end":1908,"name":"part of S. Toluca St. (26). and second block south gone","title":"Was Brook before

Rails JSON API layouts with Jbuilder (or other)

由 心不动则不痛 提交于 2019-12-04 08:38:57
问题 In my rails 3.2 app, I'm using jbuilder to render responses from my JSON api. I want to provide a common structure to all API responses, and a layout would be the likely solution to keep my views DRY. ex: I'd like every response to be of the following form : { status: "ok|error|redirect", data: { ... JSON specific to the current view ... }, errors: [ ... ], notes: [ ... ] } (where the value for data is a json structure provided by the view, everything else is from the layout) However: I can't

由 早过忘川 提交于 2019-12-03 15:09:40
I've tried to use caching with collections (with multiple solutions) the problem is that when ever I try caching the response become slower consider the following example of a collection that renders 2 partials for every item in it (around 25 item) json.data do json.array! @organizations do |organization| json.partial! 'api/v1/organizations/organization', organization: organization json.partial! 'api/v1/organizations/links', organization: organization end end without caching the average response time is around ~38ms (on average) now with caching json.data do json.array! @organizations do
