javascript - Backbone.js manually trigger "error" on a collection -

-


If my server / jsn returns a specific status (for example no results) then i I want to fail

Problem: The default error-handler is not called (since the collection successfully receives Jason. So my idea is to use a pars function to see an error code in JSS

But how do I trigger the error-method and inform my idea (and stop trying to create the model) 

  / * Global Defined * / Defined (['underscore', 'backbone', 'model / miam '', Use 'strict use'; var SomeCollection = Backbone.collection.extend ({Model: MyModel, value: null, url: function () {Return url: "data / list" .json ";}, initialize: function (model, option) {this.zipcode = options.zipcode;}, pars: function (feedback, xhr) {if (response.status = =" OK ") {Console.info ( "Status:" + response.status; return response. Results;} Else {console.warn ("status:" + response.status + - message: "+ response.message); This.trigger ('failed') / / Return response does not work;}}}); some collection returns;});

< P> in Area near a post on my blog about things like this, unfortunately it is in Portuguese, but that Google Translate helps.

I have to handle this way 

  GetSomething: - & gt; @result = @fetch (success: () = & gt; @trigger "succesthing1" if @rot. Status 204 @ tringer "success typing 2" if @rots.gets 200 error: () => @trager "error "

Now I can hear these triggers to see and can take correct action from the server for a particular result

How to access user directory in lazarus? -

After I am trying to open file changelog.txt and it does not matter if I open it Need to have the user open it though it is always located in the ~ / directory. Enter the file here. Here is my code: Process TForm1.FormCreate (From: TObject); Var myFile: textfile; Line: String; Start AssignFile (myFile, '~ / changelog.txt'); Reset (myFile); While EOF (MyFile) does not readLn (myFile, Line); Label3.Caption: = (Label3.Capttion + Line + # 13 # 10); End; CloseFile (myFile); End; This does not work, however, if I replace ~ with the actual user name, then it works, however, I use the username of each user Can not know which will run my program.

Thanks Edit1: I have tried this, but this also includes a new line: RunCommand ('/ bin / bash', ['- - C ',' Whoami '], users); This is normal. The concept of "~" is an shell level and thus requires a separate shell elev...
