Setting a factory variable in controller in angularjs

Question

I need to set a factory variable in my controller. This variable is used for the url for returning a save function in my factory. I actually build this url as several pieces but this is a simplified version.

myApp.factory('SaveDate', ['$resource',
function saveDateFactory($resource, $http) {
  var myData = '';    
  return $resource(myData, {}, { 
    query: { method: "POST", params: {}, isArray: false },
  });                                                                               
}]);

The function from my controller looks like this:

vm.myFunction1 = function ($resource) {

  vm.myDate = '/test/MyProduct/SetSalesDate/988093099/108/2016/05/21';

  SaveDate.myData = vm.myDate;

  //this should save the date for milestones  
  SaveDate.query();
  vm.cleanUp();

};

I have tried using an object instead of a primitive but it also didn't work. I have tested and my value for SaveDate.myData is being set accurately. If I hard code a value in the spot where I declare my variable in the factory, it will save perfectly. I am just not able to pass the variable successfully from my controller to my factory. I have tried a wide variety of ways to do this including using $watch. Thanks for your help on this!

When I added a function like this:

myApp.factory('SaveDate', ['$resource',
function saveDateFactory($resource, $http) {
  var myData = {};
  myData.getMyUrl = function (urlStuff) {
    alert("in SaveDate" + urlStuff);
    return $http.get(urlStuff);
  }

  return $resource(myData.getMyUrl, {}, {  
    query: { method: "POST", params: {}, isArray: false }

Adding this function throws the following error: Unknown provider: myDataProvider <- myData <- UserListController

Make a function in your factory that takes the date param and call the function in your controller — Clint

You'll need to create a function in your factory as Clint said in the comments.

myApp.factory('SaveDate', ['$resource',
function saveDateFactory($resource, $http) {
  var myData = '';

  function setMyData(data) {
    myData = data;
  }

  return {
    setMyData: setMyData,
    resource: $resource(myData, {}, { 
      query: { method: "POST", params: {}, isArray: false },
    })
  };                                                                           
}]);

In your controller:

SaveDate.setMyData(vm.myDate);

I am getting this error since adding this- SaveDate.query is not a function. Any ideas on this?

It's SaveData.resource now.

Calling this as SaveDate.resource does not throw an error but it also fails to save the data.

John Smith Over a year ago

How do you call it? If it was SaveDate.query() before then it should be SaveDate.resource().query() now.

I can't thank you enough for your help on this!! Sometimes we get tripped up on what should be an easy little process.
