Question is: How to show data in data-view in such a way that if entity is updated some how dataview is updated too.
This is my Entity named latestReading.
Here is my page LatestReading that show latest readings. It contains three data views.
This page is not called directly, as it expect a object latestReading. Hence a micro-flow named showLatestReadingPage is executed that fetches or create latestReading object and pass it to the LatestReading page and display LatestReading page.
Here is that micro-flow.
getOrCreateLatestReading is a micro-flow that returns us the a latestReading object if it is available or create a new latestReading object if it is not already created and then returns it.
Here is that micro-flow.
These are the properties of first of the three data-views in LatestReading page as shown diagram of LatestReading Page above. Name of this DataView is TemperatureDataView
These are the properties of text widget that is inside TemperatureDataView data-view. Its name is temperatureText. It shows value of temperature in the TemperatureDataView.
And this is the caption of temperatureText text widget:
Problem is when another micro-flow updates the value of latestReading the text widget is not updated. I need to reload it by clicking on navigation link of LatestReading page again.
I need my text widget in data view to keep updating value of latestReading when it is updated my some other micro-flow
The issue is that ‘refresh in client’ only works if the microflow is executed in the same context as the page (client) that the user is seeing. For example if there is a button on the page that triggers a microflow that refreshes the client then it will update the widget. However, if the microflow is triggered by the system (e.g. a scheduled event) then these changes are in a different context. Also if another user triggers a refresh it will only refresh that user’s client. Also if one user is logged in through multiple browsers (i.e. has multiple sessions, it also means that for each session there is a different user context.
The simplest solution in this case would likely be to use an appstore widget that periodically triggers a refresh on the object displayed in the dataview, such as this one: https://appstore.home.mendix.com/link/app/27/ . Simply create nanoflow or microflow with a change action that changes no attributes but refreshes the object.

I have used Fresh MVMM. I need to pass a data from one page model to another page model without using init and reverse init.
Eg: I have one toggle button in first content page.
I need to toggled the button based on the selection in second popup page without popup the second PopPopupPageModel.
ReverseInit is worked when popup the second PopPopupPageModel and can easily pass data.
But I need to toogled the button in first page without popup the second page.
Please help...
I have a function that returns a value (e.g.27).
I am put this value to my page item (P2120_SYMPTOM_ID) and i want with this value to open with button another page (P2140).
I am going to button Link builder - target and i am using P2120_SYMPTOM_ID like this:
but unfortunatendly this value doesn't pass to my new page criteria.
How can i use this value?
If you're just navigating to another page (as opposed to opening a modal window) then use action "Submit" on your button and create a branch to the new page. That is how navigation is supposed to be done. The link builder links are generated when the page is rendered and do not pick up session values.
This is a common question, and relates to the fact the link uses values during page render, not what may have happened during interaction with the page
A common solution is presented in the Oracle forums here

Alternatively, there is a free & supported FOEX Redirect plugin that also solves this problem

I want to create a xamarin.forms application that will be used for surveying. The user would be presented by multiple pages and he would be directed to the next pages only after they are done filling the fields mentioned in the present page.
bind the Button's IsEnabled (or IsVisible) property to a bool property in your ViewModel IsPageComplete. Every time a field is completed on the page test to see if all the required fields are complete, and if they are then update the IsPageComplete property.
I'm creating a Django/JQuery/MySQL application where I pass a composite data structure 'grid' as
return render_to_response('products.html', grid)
I render 'grid' into a set of UI elements ('td', 'button', 'div' etc. encapsulated in a HTML 'table'.
A typical use case:
User clicks on a certain UI element in the table
jQUery.click() is called which creates a inner 'input' tag for the clicked element.
User can add/modify/delete text from the element.
When focus is lost, jQuery.blur() is called which reverts the original properties of the clicked element such as removing input tag etc.
jQuery.blur() also calls a AJAX function where I do a .post call to send in user modified data back to a URL (function in view).
The called function in view then commits the new changes in database and returns a 'success' event back to web page:
tc_model_instance.update(tc_id=json_data['id'])
Through this use case, as you can see the changes are immediately committed to the database as soon as user eneters data and gives up focus on a particular element. Without using DB transactions in INNODB, how do I go about creating a View-Template association such that any changes in HTML template are asynchronously reflected in the model, but not necessarily written into the database.
A related question:
If possible I'd also like to create a event based bi-directional association between rendered template and my data structures as part of the view in such a way that any changes made either in web browser's UI element or associated view's data are always in sync. I plan to use AJAX for the most purpose. Not sure if forms would make sense in this regard.
Thanks.
You could probably throw a copy of the object into the session map and all posts alter that object instead of the DB directly. Then when the user presses a save button you'd fire off another POST command to the server that would then just call session['my_object'].save().
Note though that the session object is also saved in the DB, so if you are trying to avoid hitting the DB totally what I wrote above wouldn't help.
I've added a custom button into my component's backend toolbar with this code:
JToolBarHelper::custom('libri.details','details.png','details.png','TOOLBAR_DETAILS',true);
This button needs that the admin checks one of the entries listed in the table.
You can see a screenshot here if you haven't understood what I'm talking about
The button is the one called "Dettagli" (no image at the moment).
I'm having some problems:
How do I append the checked entry's id to the address generated from the button?
I've put a details() method into the controller, it calls an instance of the model and a method inside it. The model's method returns to the controller the result of a query. How do I say to the controller to pass that result to a view called libro?
All information in the page will be sent through POST to the Joomla controller (in this case, libri). In your controller, you can use JRequest::getVar('varNameHere'); to retrieve it.
$this->setRedirect($urlOfView, $someStatusMessage)
