Question

我试图通过AngularJS ngResource'POST'传入一个数组但是遇到了麻烦。 ngResource似乎不喜欢通过params传入数组？有没有办法解决这个问题，以便做出正确的关联？

控制器

ctrl.recipe = new RecipeService();

ctrl.ingredients = IngredientService.query();

ctrl.recipe.carbs = 0;
ctrl.recipe.fat = 0;
ctrl.recipe.protein = 0;
ctrl.recipe.ingredient_ids = [];

ctrl.addRecipe = function() {
 if (Auth.isAuthenticated()) {
   ctrl.recipe.$save(function() {
     var action = "created"
     alerts.recipeSuccessAlert(action);
     $location.path('recipes');
   }); 
 } else {
    alerts.loginAlert();
  };
};

ctrl.addIngredient = function(ingredient) {
  ctrl.recipe.ingredient_ids.push(ingredient.id.toString());
  console.log(ctrl.recipe.ingredient_ids)
};

Strong Params Rails

def recipe_params 
  params.require(:recipe).permit(:title, :serves, :method, :time, :carbs, :fat, :protein, :meal_type, :user_id, :calories, ingredient_ids: []) 
end

输出

has_many通过Rails关联AngularJS'POST'$资源，如何传入数组？
