I am trying to create a new record for a model and there are fields I need to save later after the model is created.
I have the code like this
let new_model = await Model.create({ name, type}).fetch();
new_model.content = 'abc';
new_model.save();
TypeError: new_model.save is not a function
I googled, it doesn't seem like sailsjs can be done this way so I guess I have to use the update or updateOne by sails. But the thing is, name,type fields are not unique and will not be so using update will actually turn into update for ALL records. updateOne will give me errors saying there's more than one record though
Does anyone has any suggestions on what can be done here?
One other option I can think of is doing something like this with updateOne
let new_model = await Model.create({ name, type}).fetch();
// getting your content here or do something else
const content = 'abc';
new_model = await Model.updateOne({ id:new_model.id}).set({content});

I'm new developer extjs. I want to get add new record from store after add store.add(record). i use sytax like below
var newRecord = store.getNewRecords()
console.log('newRecord',newRecord);
but i can't get new record, i got output data like this newRecord:[]
Please help me
First you need to add records to store and commit changes,then get new records.
grid_store.add({'Name':"ab",'dob':"099"})
grid_store.commitChanges();
var newRecord = grid_store.getNewRecords()
console.log('newRecord',newRecord);
});
Here is a fiddle: http://jsfiddle.net/2p78md5t/3/
Say I'd like to fetch only items that contains keys: "-Ju2-oZ8sJIES8_shkTv", "-Ju2-zGVMuX9tMGfySko", and "-Ju202XUwybotkDPloeo".
var items = new Firebase("https://hello-cambodia.firebaseio.com/items");
items.orderByKey().equalTo("-Ju2-gVQbXNgxMlojo-T").once('value', function(snap1){
items.orderByKey().equalTo("-Ju2-zGVMuX9tMGfySko").once('value', function(snap2){
items.orderByKey().equalTo("-Ju202XUwybotkDPloeo").once('value', function(snap3){
console.log(snap1.val());
console.log(snap2.val());
console.log(snap3.val());
})
})
});
I don't feel that this is the right way to fetch the items, especially, when I have 1000 keys over to fetch from.
If possible, I really hope for something where I can give a set of array
like
var itemKeys = ["-Ju2-gVQbXNgxMlojo-T","-Ju2-zGVMuX9tMGfySko", "-Ju202XUwybotkDPloeo"];
var items = new Firebase("https://hello-cambodia.firebaseio.com/items");
items.orderByKey().equalTo(itemKeys).once('value', function(snap){
console.log(snap.val());
});
Any suggestions would be appreciated.
Thanks
Doing this:
items.orderByKey().equalTo("-Ju2-gVQbXNgxMlojo-T")
Gives exactly the same result as:
items.child("-Ju2-gVQbXNgxMlojo-T")
But the latter is not only more readable, it will also prevent the need for scanning indexes.
But what you have to answer is why want to select these three items? Is it because they all have the same status? Because they fell into a specific date range? Because the user selected them in a list? As soon as you can identify the reason for selecting these three items, you can look to convert the selection into a query. E.g.
var recentItems = ref.orderByChild("createdTimestamp")
.startAt(Date.now() - 24*60*60*1000)
.endAt(Date.now());
recentItems.on('child_added'...
This query would give you the items of the past day, if you had a field with the timestamp.
You can use Firebase child. For example,
var currFirebaseRoom = new Firebase(yourFirebaseURL)
var userRef = currFirebaseRoom.child('users');
Now you can access this child with
userRef.on('value', function(userSnapshot) {
//your code
}
You generally should not be access things using the Firebase keys. Create a child called data and put all your values there and then you can access them through that child reference.
i want to create a registration form that will be in batch with a continuation button, getting the id of the entry will help me to call the save method.
I want to immediately get the primary key of a new Entry Created using BreezeJS, Pls i need help on this.
Thanks
Not entirely sure I understand your question, but it sounds like you want to get the id of a newly saved record immediately after the save. If so then the answer below applies.
When the save promise resolves it returns both the list of saved entities as well as a keyMappings array for any entities whose ids changed as a result of the save. i.e. a mapping from temporary to real ids. i.e. (Documented here: http://www.breezejs.com/sites/all/apidocs/classes/EntityManager.html#method_saveChanges)
myEntityManager.saveChanges().then(function (saveResult) {
// entities is an array of entities that were just saved.
var entitites = saveResult.entities;
var keyMappings = saveResult.keyMappings;
keyMappings.forEach(function(km) {
var tempId = km.tempValue;
var newId = km.realValue;
});
});
On the other hand if you have an entity and you just want its 'key' you can use the EntityAspect.getKey method. (see http://www.breezejs.com/sites/all/apidocs/classes/EntityAspect.html#method_getKey)
// assume order is an order entity attached to an EntityManager.
var entityKey = order.entityAspect.getKey();
I open a windows with a form in it and call code as follows:
var formWindow = Ext.create('widget.recordform'),
form = formWindow.down('form').getForm(),
model = Ext.create('model.record');
form.loadRecord(model);
formWindow.show();
Then, in the save event, when I determine this was a new record and not an update, I call code like this:
if (
var id = store.getTotalCount() + 1;
record.set("id", id);
store.add(record);
}
The problem is I'm getting a PUT (update) generated through my rest proxy and not a POST (insert). The doc shows that somehow Ext knows that the record is new (maybe from the Ext.create?) and then knows to make this an insert.
In any case, I'm getting a PUT which means I don't get a new record. What am I missing here?
The attribute you're looking for is phantom. If you want to prevent the record to be phantom, you need to set its idProperty along when you create it:
Ext.create('model.record', {
id: store.getTotalCount() + 1
});
(assuming id is your idProperty, which is the default)
Alternatively, you could also commit the record after you've set its idProperty and before you add it to the store, which should also set the phantom flag to false.
I am new to code igniter data mapper. I have a table called user, and I am trying to retrieve data from the database table and show them to the user.
Here is what I have in the model:
$u=new User();
$results=$u->get_by_user_id($id);
//$results here will be set to huge bunch of none sense data( which also includes the row that I am looking for as well)
if ($u->exists())
{
foreach ($results->all as $row){
$data['user']['first_name']=($row->user_first); //this where I am stuck ..
$data['user']['last_name']=($row->user_last);//this is also where I am stuck..
}
I don't know how to treat results to get a required fields I am looking for and store them in the $data I am passing to the user to view.
Thanks!
When you call get_by_x() on the model, the fields will be populated with data and you can access them like this:
$u = new User();
$u->get_by_user_id($id);
if($u->exists())
{
// you can access the table columns as object fields
$data['user']['first'] = $u->first;
$data['user']['last'] = $u->last;
}
else
{
$data['error'] = 'No such user!';
}
Have a look at the documentation which is really helpful: see Get and Get By.
Also, DataMapper expects all tables to have an id column: see Table Naming Rules. If your column is named id you should then call $u->get_by_id($id) instead of $u->get_by_user_id($id).
