analysis of oj.collection to ko.observablearray

Hello

I want to fill the options of a select statement, resting in the database.

For this I created this selection:

img1.jpg

I founded this selection on this example: binding Oracle JET - Select - Options

In this example, the options are based on an observablearray.

To get the data from the database, I created a REST service.

This is the code that I use. I based this code on this example: http://www.oracle.com/webfolder/technetwork/jet/uiComponents-table-ojCollectionTable.html

I can't understand what the structure of the collection. I know that it is an object.

How can I convert the Collection to an observablearray if I can use the data in the selectbox?

What is the way to do it? Or should I use $.ajax with a GET method?

Herman

Hi Herman,.

The ojCollection seems that it would be a lot of overhead to get only the data that you read once and use from there.  You won't need to make any updates or deletions in the purpose you describe.  Or at least I don't think you want.

For the situation you have described, I have just to make a call from $getJSON and work with this data.

Describe your observableArray at the top of your viewModel

Self.browsers = ko.observableArray([]);

Extract the data and update the observableArray, and then refresh the component ojSelect to ask that the DOM elements inside have changed.

$.getJSON ("js/departments.json",

function (data) {}

Self.browsers (Data.browsers);

$('#select').ojSelect ('refresh');

});

  • Amount fire rule script

    Hello

    I'm looking to generate a report that describes a set of rules and the number of times where these rules have triggered alarms, similar to the information, you can find via rule Diagnostics > Diagnostic details. I think I need to use the methods RuletteStats, under foglightserver/console/script-help/index.html, but it is not documentation.

    The question arises with obtaining the amount of times that have triggered alarms, I can find the name rules fairly easily. In addition, it is possible to get exactly the amount of time the alarms have shot for a certain period of time or is just the number of times that alarms fired altogether?

    Thanks for your suggestions in advance.

  • Want to transfer metadata between batches of image files

    I'm starting a major project to analyse and annotate collection large photo of my family.  I want to be able to scan pictures in very high resolution, then send lower resolution copies of the pictures to my parents, who live in another State, to annotate.  To do this, I was wondering if all of us who work in Lightroom would be the best approach.  My question is about how to transfer metadata additions my parents made on copies of lower resolution image files in files high resolution, I had planned to stay on my computer at the moment.  I thought about putting all the pictures in a file hierarchy, assigning file names when I Scan photos and sending of various subsets of the file tree at my parents to annotate.  Once they have made mark a group of image files, I would try to merge the metadata for this group of files in my files corresponding high-resolution.

    There are thousands of pictures, so I would like to send lots of pictures of them to annotate and receive lots returns with metadata to merge in my files.  Each annotated file potentially has this unique metadata file and needs to be associated with its file high-resolution correspoinding.

    I am very new to Adobe applications that appear to be candidates for this type of work (elements of Lightroom, Bridge).  I see a few possible solutions but do not know what will be best.  Can anyone help point me in the right direction?  At this point, I am very open to all options.  I am also a professional software developer and you could write the code, if necessary, but I want only to go down that path if I really have to.

    Thank you!

    David Madrian

    Do you have parents Lightroom? If Yes, then it is simple:

    1. export a subset as catalog with previews and without original.
    2. send to parents,
    3. Let them open the catalogue and annotate,
    4. receive the catalogue of their parents,
    5. import in your main catalog.

    If not, I think with this workaround:

    1. Select a subset, save metadata (this is important!) and export with the originals to an intermediate catalog,.
    2. Navigate to your folder of intermediate catalog, find the originals exported and the batch-under-sampled them for sending.
    3. Send files sous-échantillonnées parents.
    4. Ask them to annotate files with a few good utility that uses good fileds IPTC or XMP (not some metadata owners). The ExifTool GUI free might work well.
    5. Receive files and write sous-échantillonnées intermediate catalog files. Now the files include annotations.
    6. Intermediate catalog open and reading metadata. Now the intermediate catalogue with annotations.
    7. Open the main catalog and import the intermediate catalog. The main catalogue now has annotations.

    In both cases, make sure that you do not touch the current subset until your parents return the files, otherwise later import will overwrite the work you have done on the same files.

  • NEED HELP as soon as possible - the ArrayCollection collection analysis

    Hi all

    My web service returns a collection of table as follows with the following columns: name, ID, power, time.

    An example of the full collection would be: name Power Hour

    Texas                 5                    6

    New York 6.4 6

    2.1 the California 6

    Texas                 5.1                 7

    New York 6.5 7

    2.6 California 7

    I wish that my histogram of having another series for each different name so they would side Side(x axis = hour, y axis = power), now my problem is that I can't link the original collection of table to a chart I want.  So I need to change the table something like this:(I think)

    Time New York California Texas

    6          5          6.4                    2.1

    7          5.1       6.5                   2.6

    any help is greatly appreciated! Code... even more! Thank you guys!

    Yes, that's my bad.

    After looking a little closer to the example, it seems you need actually a series for each value of time, not each SiteName. You also composed the data in objects with a property name for each time value. Unfortunately, each category axis would be evenly size a SiteName with only 2 values would be the same size as the one with 10 different values. I did, however, this small example that uses stacked columns sort of you show how the series is implemented. If this does not work for you, you will have googled around to see how you can make a desabscisses with dynamic widths axis.

    Hello

    It is not currently possible to review the data the application integrated in activity or training on this basis. If you want Apple to consider adding this feature, you can suggest here:

    https://www.Apple.com/feedback/watch.html

    However, health and fitness data from other sources, iPhone, and Apple Watch are registered and grouped within the health on iPhone app. These data can be exported, which you may find useful to track the cumulative progress and/or analyze your activity more in detail.

    IPhone app activity also has a button for sharing (top right of the screen) that allows to share data - including social media, Messages, Mail, Notes, and a printer.

    Include third-party applications that can be useful, for example:

  • How do 9229 trigger by analysis of data

    Since 9229 (USB casing) has no external analog trigger; the signal lasts 12 seconds.

    I need to scan data collection the long, until the trigger threshold voltage is detected, then beginning to collect 12 seconds signal.

    But after the detection threshold, some data may already lost when the start of collection time 12 seconds.

    Also ' How do make a scan ", the scan to read th data should be in a loop. If set the duration for each big loop, then maybe the loss of data, but if too samll, then can make the Windows.

    Any suggestion how to read the analysis of data from the device. Thank you.

    Hi Turbot,

    You can just continuously sample and store the data in the table.

    If the size of the data is greater than 12 second pad just outside, and the threshold is reached, use the subset of table data to select just 12 second part.

    You can see my attached sample for more information.

  • New user: stop translates zeros unwanted data collection.

    Hello forums OR. I was hired by my University to of been research and started using labVIEW 2010 last week. I have had some success so far, but have met a few bugs that I don't know how to fix.

    My front panel has areas of entry of the user for the initial experimental settings. When the program runs it changes the current flowing in a circuit by a certain stage, and the other three devices read data. The data in graphic form as it is collected and stored in a file at the end. My teacher asked that we will be able to pause the program to change this current stage while it is running. I was able to create a routine to pause/resume using a structure of the event within my loop. This structure of the event changes the timeout of a structure of event inside-1 at the break and 1 on the resume.

    Bug 1: while the works of suspend and resume, he's suspended. I need to change tabs in windows and the program immediately starts to work again. Maybe it's a temporary problem or something to do with the lab computer. I do not know.

    Bug 2: After analysis of the data, I noticed that in the world, I stopped the program a number of lines of zeros appeared in my text file. I have my 4 my reading, my 5 my reading, readings of five 0 mA, followed by the reading of 10mA expected.

    It would be nice to delete these bugs completely, but I'm open to workarounds. For example. A method to stop the program to write a line of zeros after the first measurement of the zero.

    I realized my vi and an example of data below file. (remember, I just started to use labVIEW last week, while things are very messy.

  • Analysis and sampling frequency

    Hello

    I had a device that could do 5000Hz sampling rate to get a spectrum each sampling. I put it in a while loop with vi Peak Search to find the spectrum peaks. Therefore, I would be able to get the value of 5000 peak seconds. However, the truth is, only, I could get a value of 40 peak per second. I guess there could be delays on the tops of the research.

    Can someone tell me it would be possible to eliminate delay separating the part of sampling and part of the analysis? I think two while loops, first one collects all the spectra and the peaks of a seachs second. But do not know how to temporarily store data between these two parties.

    It's a great idea!  It's called a design ' producer/consumer '.  LabVIEW is an example and a model if you want to give it a go.  We are standing if you need assistance!

    You have to invent it independently, however.

  • Issue of data collection

    Hello

    I've written a VI that collects data continuously in a circular buffer, and is supposed to save all the points in the buffer to a file excel to an impact trigger. I currently use the scalar comparison of the limit of wave form VI to run the trigger (using the Boolean result), but after the project of the analysis, the trigger will not register for some reason any.

    Is it because VI comparison does not record the failure fast enough? Also, can anyone recommend an alternative that would more quick to use instead?

    Thank you

    Guy

    Thanks for posting the code.  It shows quite clearly the source of the problem.

    I, personally, like the model of event-driven state machine you use, but you must remember that a State Machine can be in one State at a time.  In particular, if any State takes a significant amount of time (1 State user and waiting for event take at least 0.1 sec, a 'long time' data-acquisition-speech), you can miss things.

    What you want / need is a parallel loop, alias the design of producer/consumer model.  We had a similar situation involving a trigger, a "buffer of pre-event", and want to save the data.  Here's how we handled IT:

    • We had two pads - a pre-event buffer appropriate to save data before the trigger and a big enough post-event for "catch-up game" (we probably set to-1, as empirically, it remained small, 4-6).
    • We had a VIG/FGV who if we were in the phase "Pre-event" or "after the event" to save data in the memory.  We started in pre-event.
    • We had a Test for the State of relaxation.  If that's true, we put one Notifier "Start Saving."  In both cases, we then called «Get a sample»
    • Get a sample took a sample and, depending on whether we were before or after the event, put on the front or after the event queue.
    • We had a parallel loop waiting for the notifier (so it was essentially "suspended" until an event has occurred).  Once he fired, it meant that the loop of producer just changed from pre-event in retrospect, that the prior event queue was ready to be processed, and when we're done, we need treat the queue after the event, until we had treated enough data.  Treatment of the prior event queue is easy - empty the queue and use its components.  Similarly, the queue after event processing is also simple.

    Note - It was 4-5 years since I developed this system and realize I'm missing a few details.  I think we needed to fire the declarant after get a sample, information passing on the question of whether we are in a State "Trigger not yet ', a 'First trigger' or a State of"waiting for Godot"(meaning as much post-event data treatment) required.  I don't also forget how we treated fills the buffer "Pre-event" - we did ignore triggers if we did not have enough 'Before' data?  I don't remember.

    But, again, the trick is to backup data in a queue (the producer) course in a loop that is different than the process of emptying the queue (the consumer), so that the dump process does not interfere with the acquisition process.

  • Analysis of traffic do not work after update v6.7

    Hi all

    I got SFlow installation on a Force10 S50 and Netflow on a Cisco ASA5510 facility and has been successfully collecting data for both devices. Friday morning around 12 h 40, Foglight updated itself to the version 6.7.24321 and since then I have not received the data stream of each device and traffic analysis tab no longer appears on each object. I rebooted the Foglight Server, checked the Windows Firewall settings and verified that the configuration of the flow on the network devices have not changed, but nothing has solved the problem. I tried the reactivation of analysis of traffic on the two aircraft in Foglight but still not received the data stream.

    Anyone else who upgraded to v6.7 has similar problems?
