Question

I have a problem that’s bugging me.

I have a grid and when i dblclick on a item I want to open a window to edit that item. Pretty standard stuff. The problem is, i want to be sure the record is up to date, because other people using the program may have changed it or even deleted it.

I could reload the store, but i only want one specific record to be checked… So i figured i would just go get the data, build another record and replace the existing one in the store but i really want to know the best way to do this

Bear in mind RESTful proxy is not an option for me, even though i don’t know if the update operation works in this case ( server -> client).

EDIT:
this may help somebody:
all i did was copy the data and raw objects from the new record to the old one and then “commit” the changes. worked for me.

Thank you.

The best way to do something like this would be to reload the record in the event which opens the window. So where you would for example load the record from the grid store into a form within the window, you can use your model to load from the id.

Item.load(id, { success: function(r) { form.loadRecord(r); } });

Once saved, you should probably also call refresh on the grid view, which will redraw the changes from the save event. You can also use refreshNode (see grid view documentation) on the exact record in the store if you’re concerned about performance.

Of course you do not have to use the restful proxy with this, you can use any proxy as long as it will load the single record.
