Default $resource POST data

Question

That might be strange but I need to specify some default POST data for my $resource using the factory method of the module.

Does anyone have an idea of how to do that in

I think it will depend on how you call the update function. If you read the angular main page's tutorial, under "Wire up a Backend", the mongolab.js provides a 'Project' factory. Copied verbatim:

angular.module('mongolab', ['ngResource']).
factory('Project', function($resource) {
  var Project = $resource('https://api.mongolab.com/api/1/databases' +
      '/angularjs/collections/projects/:id',
      { apiKey: '4f847ad3e4b08a2eed5f3b54' }, {
        update: { method: 'PUT' }
      }
  );

  Project.prototype.update = function(cb) {
    return Project.update({id: this._id.$oid},
        angular.extend({}, this, {_id:undefined}), cb);
  };

  Project.prototype.destroy = function(cb) {
    return Project.remove({id: this._id.$oid}, cb);
  };

  return Project;
});

The usage is that you first get an instance of the Project:

project = Project.get({id:1});

Then do an update after some changes:

project.update(someFunction);

In your case, you can change the update to always add the data you need:

Product.prototype.update = function(cb) {
  return Product.update({},
      angular.extend({}, this, {someDataKey: someDataValue}), cb);
};

Otherwise, you can most likely put the key/value pair in the params:

    update: {method : "POST", params:{someDataKey: someDataValue}}

It will be POSTed with the key/value pair in the URL, but most app servers nowadays will throw the pair into the params object anyway.
