Saving users table customisation [message #1401314]

My evaluation of the Scout framework progresses. Now the features I am investigating getting a bit more special I guess.
Currently I try to find a way to save the customisations a user does to a table that is displayed inside a form. Like changing the order of the columns or a sepcific combination of filters/sorts. Is this somehow possible to achieve?

Hi Lukas,

yes, we do have a concept for this. We use a cache. See this post for more information.

If you have more questions, please let us know.

Best regards,
Matthias

In my case this behaviour is not existing. It does not even save when I am activating another page and then going back to the page where I did the changes. Could it be related to how I implemented the table? I deactivated the visibility of the default table of the tablepage and replaced it by a layoutform that contains three other forms. One of these forms is the form containing the table where the user settings should be saved.

TablePage (with deactivated table)
 -layoutform

  --form1

  --tableform (this file contains the table that is actually displayed)
   ---mainbox
   ----tablefield
   -----displayed table

  --form3

Maybe I have unchecked a box or something that influences the cache? Or it has something to do with running it from eclipse?
However the prefs file is generated in the suggested location from the other article.

I have still no solution for my problem. I have read the article recommended by Matthias closely, but I cannot see how to address my problem, as this article approaches it from the side of trying to deactivate caching for the Table of a TablePage.

Does this preference service work if you are using anonymous users? Is it an issue that I am not using the default tables of the TablePage but using a form with a TableField embedded in another form? Does a way exist to enable this caching mechanism for TableFields?

Hi Lukas,

I am sorry that I can't provide a full solution yet, I am very busy. But I think the class you need to look into is

org.eclipse.scout.rt.client.ui.ClientUIPreferences

. This class has methods which may help:

hasTableColumnPreferences(ITable)
setAllTableColumnPreferences(ITable table)
setTableColumnPreferences(IColumn col)
getTableColumnWidth(IColumn col, int defaultWidth)
getTableColumnVisible(IColumn col, boolean defaultValue)
...

The solution to my problem seems to be calling initTable() after creating a new instance of the tableForm as pointed out by Jeremie in the context of another issue: https://www.eclipse.org/forums/index.php/mv/msg/235749/1404471/#msg_1404471
Maybe instantiating a form with a TableField misses this method call. When adding it manually it works.

After experimenting a bit with this now working feature I realised that in my current setting there is just a single file for all clients to save these settings when running it locally. This means independently with which user I use the application, always the same settings are loaded. So if user A does a change then user B has the same change applied to his UI as well when starting the application the next time. In the Link Matthias shared in the second post it is mentioned that there is a way to store these preferences for each user in a database. Could anyone help me to find the information how to achieve this? Until now I only found the information that it is possible in Matthias' link but nowhere any hints how to achieve this.

Hi Lukas,

I experienced the same behavior.
Here is a way to solve your problem:

Before calling AbstractTable#initTable() you need to set a UserPreferenceContext:

getTable().setUserPreferenceContext(userId);
getTable().initTable()

Where the userId is a String. In my case I obtain the userId from the ClientSession where I have overridden the "getUserId" method.

Hope this helps,
Matthias

Thank you Matthias, that solved the issue with the different customisations for different users. Regarding a way to store the customisation in a database as mentioned in the thread you posted in the beginning: Do you have any ideas where to start to realise that?

Hi Lukas,
I did not try but I suppose the following.

The preferences are stored by using the

IUserPreferencesStorageService

.

Currently, the

FileSystemUserPreferencesStorageService implements IUserPreferencesStorageService

will be used. If you wanted to save it in a Database, you would need to create your own implementation like this:

DatabaseUserPreferencesStorageService implements IUserPreferenceStorageService

Accordingly, when you call

IUserPreferencesStorageService

your DataBaseService will be used instead
