Hello everyone, i come from the filemaker world and want to move on. We have created a little app to look after displaying a schedule of dances for a competition. here is a screen shot: http://www.tbcguy.com/dvpro/theviewlist.PNG. Now FMPro runs only IOS (iphone) for mobile devices. We could use web direct for android devices but that involves AWS or other server means. Or we need a server and tons of client licences. At any rate this is an app that has static data, display only…no user intervention apart from searching. There could be changes in the dance categories, times etc. But, that is controlled by someone in the backend. Right now we have it set up to use google sheets. The app checks to see if there are changes in the data, if so do an update and notify the user. Also if you notice, at the bottom above the menu bar there is a current dance. That is schedule based meaning it checks the current time and compares it to the data and displays the current dance. If there are discrepancies, which there are like falling behind or it runs smoothly and gets ahead. we can adjust that on another screen. I would like to move away from filemaker if possible and do this another way and this Ionic framework looks really slick. My hope is to design this in this framework. Using Appscript from google I have a firebase database set up that is synced to the google sheet. I am hoping that this framework can tie into Firebase realtime and display the data similar to the screen shot. Then my data on the phone will be updated all the time.

That brings me to my question. Is this possible using the IONIC / angular framework. I have basic programming skills…again a database guy. But looking at some of the tutorials for this, it looks manageable and I am up for the challenge as well.

Thanks for your time.

Hi, I need to get records from Firebase and store them locally in my Ionic 3 app such that every time I open the app, it checks Firebase for changes and updates the local one if need be. It needs to be listening for changes even when the app is closed. Kinda like an email app (when you open an email app, all the previous messages are already there - no need to redownload from the server - and is updated when new messages arrive).

Right now, every time I load the app, it pulls fresh data from Firebase, and when I navigate to a different page and return, it does a fresh pull of data. I’d rather it get all the data one time and store locally, only updating when there’s a change. It should also be listening to Firebase for changes.

How do I achieve that?

Thanks.

Am starting a new project on ionic version 3.20

Every time I update a file, the web page isn’t refreshing/rebuilding, where it suppose to live reload on “localhost:8100”. So am stopping ionic and run “ionic serve” again on every update.

Although when i refresh the web page (localhost:8100) the page is reloading till infinity.

I have uninstall cordova and ionic, and still same issue.

Any solutions please?

Hi All,

I’m facing some problems with theming ionic components (v4) and shadow DOM. In my ionic-pwa from stencil I even don’t get it to work.

For example:
<ion-button fill="solid" expand="full" color="success">Success</ion-button>

Without shadow DOM enabled this results in a success button as expected.
With shadow DOM enabled, the ion-color-base variable doesn’t seem to point to the success color.

To reproduce it:

1. Install https://github.com/ionic-team/ionic-pwa-toolkit
2. Go to this file: https://github.com/ionic-team/ionic-pwa-toolkit/blob/master/src/components/app-home/app-home.tsx
3. add ‘shadow: true’ after rule 5.
4. add ‘color=“success”’ to the ion-button

Regards, Peter

ok, i have been searching the web for hours now and found a lot of results but no working ones

I am developing a app in ionic 4. Up till now i was using my local “api” to test (which works) but now i want to test it with the live version which is build using laravel - it is a exact copy of the local version but then live on the domain.

I have installed https://github.com/barryvdh/laravel-cors to handle the cors and when i test the cors on https://www.test-cors.org it shows:

date: Fri, 07 Jun 2019 22:18:39 GMT
content-encoding: gzip
server: Google Frontend
access-control-allow-origin: *
etag: "1rO4KQ"
allow: POST, GET, OPTIONS, PUT, DELETE
access-control-allow-methods: POST, GET, OPTIONS, PUT, DELETE
content-type: text/html
status: 200
x-cloud-trace-context: c463d031b08229c22feccaba743c28a5
cache-control: public, max-age=600
access-control-allow-headers: access-control-allow-headers,access-control-allow-methods,access-control-allow-origin,content-type
expires: Fri, 07 Jun 2019 22:28:39 GMT

so i guess my server side cors is ok. Now in ionic im doing the following:

  getPartnersForZipcode(zipcode: string): Observable<any> {
return this.http.post(this.baseUrl+'/search-partners', {zipcode:zipcode}, this.httpOptions).pipe(
    map(results => results),
);

as http options im using

 httpOptions = {
headers: new HttpHeaders({
  'Content-Type': 'application/json',
  'Access-Control-Allow-Origin':'*',
  'Access-Control-Allow-Methods':'POST, GET, PUT, OPTIONS, DELETE, PATCH',
  'Access-Control-Allow-Headers': 'Content-Type, Access-Control-Allow-Headers, Authorization, X-Requested-With',
})

*I tried it also with no headers, also with only content type etc… none made a difference

which is using the package import { HttpClient, HttpHeaders, HttpErrorResponse } from '@angular/common/http';

In postman i get a good response with data

Screenshot 2019-06-08 at 00.29.59.png1780×390 36.3 KB

but in ionic (using ionic --serve and devapp on device (ios)) im getting CORS error

Screenshot 2019-06-08 at 00.25.45.png2656×696 135 KB

…i dont know whats happening… why do my requests dont work in ionic?

Does it not work with Ionic 4?
I am importing in my app.module:

<ion-calendar [(ngModel)]="date"

</ion-calendar>

I’m getting the error:
Can’t bind to ‘ngModel’ since it isn’t a known property of ‘ion-calendar’.

1. If ‘ion-calendar’ is an Angular component and it has ‘ngModel’ input, then verify that it is part of this module.
2. If ‘ion-calendar’ is a Web Component then add ‘CUSTOM_ELEMENTS_SCHEMA’ to the ‘@NgModule.schemas’ of this component to suppress this message.
3. To allow any property add ‘NO_ERRORS_SCHEMA’ to the ‘@NgModule.schemas’ of this component
