javascript - Accessing nested route parameter from parent route/template -

i have nested route behaves less-nested version of itself:

/code/class/myfile.java /code/coverage/:coverageid/class/myfile.java 

somewhat self-explanatory, coverage route decorates page additional highlighting/details not present in "normal" version.

however, code template defines sidebar includes navigation tree access other code files. when viewing /coverage/ page, sidebar display links differently, ensuring nested route maintained when clicking around.

my problem:

i can't seem find way access :coverageid in code route or template modify way links displayed. code route:

export default ember.route.extend({   model(params) {     console.log('coverage id: ' + params.coverageid);       ... 

prints undefined. seems make sense since it's child parameter, "out of scope"?

my incorrect solution:

i tried in class route:

export default ember.route.extend({   model(params) {     var parentmodel = this.modelfor('code');     parentmodel.coverageid = params.coverageid;     ... 

which, in code.hbs template:

{{#if model.coverageid}}   {{#link-to 'code.coverage.class' model.coverageid filename}}{{filename}}   {{/link-to}} {{else}}   {{#link-to 'code.class' filename}}{{filename}}{{/link-to}} {{/if}} 

actually works! link produced when viewing coverage route.

however: while can right-click of these links open them in separate tab successfully, if regularly click them, receive error:

error: assertion failed: must use ember.set() set `coverageid` property (of [object object]) `425988` 

but of course, can't use parentmodel.set('coverageid', params.coverageid);, because fails with:

typeerror: parentmodel.set not function 

so! how can either (1) examine nested route parameters in parent (code) route, or (2) inject known value (:coverageid) child route into parent?

you rid of .set not function error using global ember.set.

so, instead of:

parentmodel.coverageid = params.coverageid; 

try:

ember.set(parentmodel, 'coverageid', params.coverageid);
