reload page

usr338

Hi, How To reload page (like F5) in front end function ? calling javascript function like location.reload doesn't work in front end function!

gabriel

Frontend functions are not able to reload the browser. r3 apps can reload their data or UI state without a page refresh. A reload should never be required.

Why do you want to reload the page?

gabriel I am trying to do something like what policy do for tables.I am trying to let user select what data is working with. to do that i show notification in header to determine the current data (something like current organization that user works in), user can switch between data by clicking on notification and change the current data by popup form showing through notification click. when current accessible data is changed ( like current organization), underlying form that is open for now should be updated to show accessible data.

gabriel

To update the current form, you can use app.form_open() with the ID of the current form. The form then reloads and can trigger functions on form load, if you need them.

Though I had real trouble understanding what you are trying to do, so my suggestion might not fit your case. What do you mean by "something like what policy do for tables"?

gabriel Thank you for response. actually i should say something like filter, but filter for all forms. i can't use app.open_form(), because it only works for current opened form and not underlying form(i open a popup form by clicking on notification that will filter accessible data for all other form, so underlying opened form should be reload to filter applied).
i can open notification form in full windows and after applying filter (saving accessible data) navigate back to previous form, but it is not appealing enough.) another problem that exist is that if underlying form is opened in edit mode, it's data should not change to new filtered data and should be closed by popup filter form.

A page reload is technically possible to implement into the standard feature set, but should never be necessary - so I would want to avoid it if possible.

To find out, if there is an edge case, where you absolutely need to reload the page, I need to understand how your use case works. Could you please elaborate on these questions?

How are you filtering data for "all forms"? Are you writing something in a variable that other forms then use to filter with? Or are you updating a collection which is then used to filter? Or something else?
How do you keep your state between reloads? If you reload the page, everything you have done in the frontend (variables, states, collections), would be reset. How do you keep the chosen filters?

gabriel Hi again

How are you filtering data for "all forms"?

I have a table that hold refrence to last active or available data for logged in user(and for each login) .using form opened by notification form, i let user change the active(or filter accessibale) data. this data can be used by policy functions or queries inside other forms for global filtering purpose.

How do you keep your state between reloads?

actually in my senario, by changing active data, all states should be recalculated for each open form and it will be happend in 'form loaded' events of form. all collection doesn't need to be refetched, thoes need to be updated has relation to active data table in their query, but you are right i didn't thought about collection!! my be i should update every collection related to this change in popup notification form too(not cool!)
also forms that are in edit mood should be closed somehow, because may editing record are not valid with last filter applied.(be not valid or accessible data for current time)

a senario for such global filtering is some thing like this: suppose logged in user can work with data related to more than one department or building . instead of selecting active building in each form, user can see the active building in header and work with just related data to each building in all other forms.

My be it will be a good idea to let opened forms can be able send signals and data to each other directly(when a popup and full screen form are showing in the same time)

This is already possible with variables in R3.9. Using global variables (eg. not assigned to one form), you can change state in one form, which is automatically applied to all other forms using the same variable. Filters are updated, states are changed, and so on. If you want to keep your current setup, you can set a variable in the notification form and will apply everywhere.

Changing states via a relation in the backend, then using this data to filter things within the current user session, is quite a complicated solution. I suspect, using variables will give you the same result with much less effort and without the need to reload a page.

gabriel does it mean if variable changes, all other forms that use variable will be refreshed automatically ?

gabriel

Everything that uses a variable is automatically refreshed. This can be list filters, form states, filters for relationship inputs, etc.

gabriel
unfortunately using variables doesn't work for my scenario, because i need to variable be accessible in all other application in platform but each application can access it's variable only.(notification will be shown in header for all application not just for creator of it)

gabriel

We are still looking at the question, if we can make variables accessible in dependent apps. No update there yet unfortunately.

gabriel thanks for response.
