I have a requirement where I need to store local settings of user into some cache object. I tried to implement this using $cacheFactory e.g.
var userCache = $cacheFactory('users');
However, when my code hit this line again, it gives me following error:
Error : cacheId 'users' is already taken !
I am not sure, how to check if this ID is already exists, because I need to fetch settings from this cache object on each time component loads.
It's actually listed how to do this on the documentation page:
The $cacheFactory() function is not a "get or create" call, it's only a create.
This is how you would check if the cache has already been created:
if (!$cacheFactory.get('users')) {
var userCache = $cacheFactory('users');
}
which can be changed to
var userCache = $cacheFactory.get('users') || $cacheFactory('users');

Using a Postman to retrieve data from our project management platform that provides collections (Teamwork)
I retrieve a first list of project ID from the Get request using the following code in the Test of that first Get request :
`var jsonData = JSON.parse(responseBody);
var list = (jsonData.projects).length;
var a=[];
for (var i = 0; i < list; i++)
{
var counter = jsonData.projects[i];
IDs=counter.id
a.push(IDs)
}
postman.setEnvironmentVariable("id", a);`
That create a variable id which contains a list of id.
After that, I want to go through each of these id in the following request (replacing {id})
{{Domain}}/projects/{id}/rates.json
Domain is set in the environment variable and is working.
What code and where do i need to put it (Pre-script? Test?) so I can go through the list? That second get request would give me the employee rates in each project (identified by those id)
Thanks for your help
If you want to use the list of variables you extract from the first GET in URLs for subsequent calls, then I think you would need to use the pm.sendRequest option in the 'Test' tab of your first GET.
There is a really good example in this thread:
How to run one request from another using Pre-request Script in Postman
Note: The pre-req tab is executed before the API call is made and the test tab is executed after the API call is made.
Also, "postman." is using the old API, you would benefit from using the newer API which is "pm." so for example;
pm.environment.set("variable_key", "variable_value");
More info on this can be found here:

Here is my simple angular 1 app.
Source code here.
Basically it is a copy of this.
I am able to do CRUD operations. The issue is that, when I delete a record. It redirects back to the home page. The record I deleted is still here. If I refresh the page, it is gone.
Is it a way to delete a record and then after redirect, I should see the latest list?
Update 1:
Unfortunately, it is still unresolved. Something strange that it seems the promise in resolve is cached. I added a few console.log inside the code. You can see the code flow. Open chrome developer tool to see it.
i review you code , the problem is here:
this.deleteContact = function(contactId) {
var url = backend_server + "/contacts/" + contactId;
// actually http delete
return $http.delete(url)
.then(function(response) {
return response;
}, function(response) {
alert("Error deleting this contact.");
console.log(response);
});
}
if you have service to manage your contact use there to call your server to delete the contact.
the reason you cannot delete without refresh is:
your delete from DB but not from angular array.
must review (update the scope (array))
your code is hard to read , i have suggestion for you, using:
broserfy , watchify
lodash
and backen use mvc
You delete it remotely but not locally. So you can see result only after refreshing (only after you requesting updated data from server). You need to update your local contacts after you succeed on server side.
$scope.deleteContact = function(contactId) {
Contacts.deleteContact(contactId).then(function(data){
...
//DELETE YOU LOCAL CONTACT HERE
...
$location.path("/");
});
}
I didn't look deeply into your code, so I can't say how exactly you should do it, but as I see you keep your local contacts in $scope.contacts in your ListController.
I am trying to create a 'Favorites' section in my app where you hit a button and it is added to a user favorites list in firebase. I am using the ionic platform.
I created a factory to handle the favourites as they come in. and i use the getAuth() function to get the unique userID so i can just pull it when the user logs on. This is my attempt but i am not getting the result i wanted which is simply something like :
< userid >:
{
0: "fav1"
1: "fav2"
}
.factory('Favourites',function($firebaseArray){
var ref = new Firebase("https://experiencett.firebaseio.com/");
var authData = ref.getAuth();
var favs = $firebaseArray(new Firebase('https://experiencett.firebaseio.com/favourites/'+authData.uid+''));
return {
all: function() {
return favs;
},
add: function(){
var up=new Firebase('https://experiencett.firebaseio.com/favourites/');
var usersref=up.child(authData.uid);
usersref.push({3:"paria"});
},
When you call push() you are generating a unique id. While that is great for many use-cases, it is not good here since you want to control the path that is written.
Since you're already constructing the path with child(authData.uid) you can simply update it with update():
usersref.child(authData.uid).update({3: "paria"});
This will either update the existing value at 3 or write the new value for 3, leaving all other keys under /users/<uid> unmodified.
Alternatively if you want to replace the data that already exists at users/<users>, you can use set() instead of update().
This is all covered in the Firebase JavaScript SDK in the section on storing user data. It is not covered in the AngularFire documentation, since there is nothing specific to Angular about it.
I have the following publisher and subscriber code.
It works for the first time when the app starts, but when I try to insert data directly into the Mongo database, it will not automatically update the user screen or I don't see the alert popping.
Am I missing something?
Publish
Meteor.publish('userConnections', function(){
if(!this.userId){
return;
}
return Connections.find({userId: this.userId});
})
Subscribe
$scope.$meteorSubscribe('userConnections').then(function () {
var userContacts = $scope.$meteorCollection(Connections);
alert("subscriber userConnections is called");
if (userContacts && userContacts[0]) {
....
}
}, false);
First off, if you are not using angular-meteor 1.3 you should be. The API has changed a lot. $meteorSubscribe has been deprecated!
To directly answer your question, $meteorSubscribe is a promise that gets resolved (only once) when the subscription is ready. So, it will only ever be called once. If you look at the documentation for subscribe you'll see how to make the binding "reactive", by assigning it to a scope variable. In your case it would be something like:
$scope.userContacts = $scope.$meteorCollection(Connections);
Doing it this way, when the collection gets updated, the $scope.userContacts should get updated as well.
I'm trying to understand the correct workflow to create a $setPristine equivalent with my Firebase data.
My workflow is as follows:
1) Create Firebase object (via the Angularfire Generator 'SyncData')
2) Form data modifies the $firebase object.
3) To update the remote model, I use myRef.$save()
All of that works well. Now, I'm trying to add a "reset" button on the form, so that the locally modified data will revert back to the remotely stored data.
So far, I'm running into problems. I've tried reinitializing the firebase reference eg myRef = syncData('/my/path') but not only does that now work, but it is destroying the remote data object!
What is the correct way to re-pull the remote data to use in my Angular model?
I know this is an old question, but I ran into this issue myself.
After some searching around I found this post: http://grokbase.com/t/gg/firebase-angular/1499haaq4j/editing-data-as-a-copy
Which led me to an outdated code snippet (2 months lol XD) from #Kato: https://gist.github.com/katowulf/8eaa39eab05a4d975cd9
I modified this to work with Firebase 2.3.1 and AngularFire 1.1.3:
app.factory('ResetFactory', function($firebaseArray) {
return $firebaseArray.$extend({
reset: function(itemOrIndex) {
var key, self;
self = this;
key = self.$keyAt(itemOrIndex);
self.$ref().child(key).once('value', function(snap) {
self.$$updated(snap);
});
}
});
});
Which can be called via:
var comments = new RevertFactory(ref.child('comments'));
# variable comment is for example an ng-repeat that's being edited
comments.reset(comment);
