ember.js - How to work with global query params -

-

i have query params don't want loose when switch 1 route another. docs, solution seems use of global query params, set on applicationcontroller.

let's setup :

  • a page list of objects displayed , criterias on left filter list. may call related controller listcontroller. criterias have query params.
  • when object first page clicked, whole page replaced detailed view of object. page need able go filtered list , consequently keep query params.

i need access applicationcontroller's global query params listcontroller manipulations. it's easy :

app.listcontroller = app.arraycontroller.extend({    needs: "application",    qp: ember.computed.alias("controllers.application"),    ....

when criteria changes, filtering operation done server side, need refresh listroute when query params changes.

how applicationroute ?

app.applicationroute = ember.route.extend({    actions: {       queryparamsdidchange: function () {          var listroute = ??????;          listroute.refresh();       }    } }

what think of whole setup ? on path ? i'm not sure...

this did.

the queryparams defined in route. "parent", implications children.

queryparams:   fooparam:      refreshmodel: true

setting refreshmodel: true trigger beforemodel:, model:, , aftermodel: hooks route descendant routes. currently, there no way individually turn on or off behavior descendants.

and controller

queryparams: ['fooparam'] fooparam: null

queryparams hook in controller not override queryparams hook in route, rather, necessary , complementary entire functionality work. should not put of these belonging in controller in route, or belongs in route in controller.

all query parameter keys need defined in controller well. value of hook default value. still change according query parameter.

then, descendant route, 

model: ->   this.modelfor('parent').filterby('childattribute', this.paramsfor('parent').fooparam)

or if want 1 (the first default) record:

model: ->   this.modelfor('parent').findby('childattribute', this.paramsfor('parent').fooparam)

i used pyinstaller create standalone exe file pyqt project. did not use single file option because exe created single file option takes long open. therefore, pyinstaller created dist folder contains bunch of files including program.exe file. create setup.exe file place contents of dist folder in program directory , create shortcut in start menu , on desktop. want super simple user. maybe setup.exe files when download program cnet. found inno-setup, looks promising. however, not know if there special considerations because program standalone program create python/pyqt program. thanks! have experience task? there program using task not know about? inno-setup or nsis easiest use. tell them files include , put them , create nice installer you. wrote short tutorial on experiences using innosetup might find helpful: http://www.blog.pythonlibrary.org/2008/08/27/packaging-wxpymail-for-distribution/ note tutorial based around wxpython app wrote, concepts same.
