ember.js - Emberjs controller needs with Binding -

-

i have nested resources:

    this.resource('foo', {path: '/foo/:foo_id'}, function() {         this.route('makesomethingwithfoo');          this.resource('bar', {path: 'bar/:bar_id'}, function() {             this.route('makesomethingwithbar');

i want use properties model foo in, while i'm in #/foo/321421/bar/231421. barindexcontroller looks this:

   ... = ember.objectcontroller.extend({     needs:'fooindex',     //mybinding: 'controllers.fooindex',     ....});

in template if use controllers.fooindex.desiredproperty can access property of model foo. wanted use mybinding in order spare writing few characters more ( controllers.fooindex). think did right, @ least seems right according documentation. error:

     uncaught error: assertion failed: cannot delegate set('my', <(subclass of       ember.objectcontroller):ember238>) 'content' property of object proxy      <(subclass of ember.objectcontroller):ember249>: 'content' undefined

the controller has model foo. fooindex route implicit nested route of foo route, , hence has controller of it's own. nested fooindexcontroller needs lookup model on it's parent routes needed.

in case bar route needs use foo instead of fooindex in needs declaration.

needs:'foo', foobinding: 'controllers.foo'

the foobinding optional. shortens lookup this.get('foo'). might want refer answer clarify nested resources in ember.

when save object, got below error must non-abstract type public parameterless constructor in order use parameter 't' in generic type or method 'servicestack.redis.redisclient.store<t>(t) redisclass.getinstnace().store(msg); // error here redisclass.getinstnace().save(); as third party's class, can not edit how save object? could create wrapper around third party object call constructor, store wrapper? e.g. public class mywrapper { public thirdpartyobject thirdpartyinstance { get; set; } public mywrapper() { thirdpartyinstance = new thirdpartyobject("constructors"); } }

i've embedded microsoft.reporting.webforms.reportviewer control in aspx. site works on mysite.com. when try exmple export report, there new black window opened address mysite.com/reserved.reportviewerwebcontrol.axd... it's working fine. but.. pass axd via proxy. mean, i'd force export use url myproxy.mysite.com/reserved.reportviewerwebcontrol.axd... redirect request mysite.com/reserved.reportviewerwebcontrol.axd... i've noticed, link build within js (that inlcuded in axd): exportreport: function(format) { if (this.exporturlbase == null) return false; window.open(this.exporturlbase + encodeuricomponent(format), "_blank"); return true; }, the url axd stored in exporturlbase . how can change proxy serwer url? it possible modify exporturlbase field in javascript. report stored in placeholder somewhere on page, once found can create call _getinternalviewer() function on gain access exporturlbase. have @ following code: ...

time series - R growth rate calculation week over week on daily timeseries data -

-
i'm trying calculate w/w growth rates entirely in r. use excel, or preprocess ruby, that's not point. data.frame example date gpv type 1 2013-04-01 12900 office 2 2013-04-02 16232 office 3 2013-04-03 10035 office i want factored 'type' , need wrap date type column weeks. , calculate week on week growth. i think need ddply group week - custom function determines if date in given week or not? then, after that, use diff , find growth b/w weeks divided previous week. then i'll plot week/week growths, or use data.frame export it. this closed had same useful ideas. update: answer ggplot: all same below, use instead of plot ggplot(data.frame(week=seq(length(gr)), gr), aes(x=week,y=gr*100)) + geom_point() + geom_smooth(method='loess') + coord_cartesian(xlim = c(.95, 10.05)) + scale_x_discrete() + ggtitle('week on week growth rate, apr 1') + ylab('growth rate %') (old, correct answer using plot) w...
