What is preventing my Grails application from retrieving an object from my Angular script?

I'm currently working on adding objects to a JSON list in Grails. Below is the Angular code I am using: http://pastebin.com/4ypijUMD

Additionally, here is my Grails controller: http://pastebin.com/skTtVtxv

My understanding is that the angularJS script should send a request to access the add controller with the information from the most recent member of the list.

Subsequently, the add function should generate a new JSON object based on the parameters passed into the controller from the angular script and everything should work smoothly.

Unfortunately, when trying to update my list using the update controller, I encounter an issue where no new objects are created and I end up getting null values.

list with my update controller:
    def saveList() {
        def newItem = Item.findById(request.JSON.id)
        newItem.name = request.JSON.name
        newItem.type = request.JSON.type
        newItem.priority = request.JSON.priority
        newItem.completed = request.JSON.completed
        newItem.save(flush: true)
        render newItem as JSON
    }

Answer №1

The method to perform the AJAX call was missing in your code snippet, only a service with a save function was shown. To achieve this functionality using Grails and Angular, your code should resemble the following example:

$http.post('http://localhost:8080/test-app/myController/addItem', { json values})
    .success(function(response) {})
    .error(function(response) {});

class MyController {
    def addItem() {}
}

Answer №2

After reviewing your code on Pastebin, it appears that you are sending a list from the browser and manipulating a single item in the server-side code. Is it possible that this is causing the issue?

Answer №3

section, it appears that there may be an issue with passing request.JSON.id from angular in your code.
                              {                                
                                 id: 1
                                 name: $scope.thing,
                                 type: $scope.worktypeSelection,
                                 priority: $scope.prioritySelection,
                                 completed: false
                                }
