User should have option to 'reset' to saved values in stead of default values

[dennisquintel]

Problem

I find it quite annoying, when you are working in a non-default scenario, often you want to go back to your 'original' slider setting, but all you can do is reset to the default setting. With singular sliders: that is doable to write down or remember the slider setting, but when you are changing a slider group, all you can do is reload the entire scenario. 😒

Slider reset

Possible solution

We might want to add a select box in the menu where you can choose your behaviour.

There are multiple ways of achieving this I guess. One way would be store all slider settings in the browser's LocalStorage (if the customer in question does not use IE7, IE6 or Opera Mini). Than I think you could easily reset to Last saved. Another more complex way would be storing multiple scenario's (like a simple versioning system).

I like the general idea though. 👍

[dennisquintel]

Good idea. We could also use the preset_scenario's user_values.

[dennisquintel]

What do you think @antw?

[antw]

We could also use the preset_scenario's user_values.

Agree. I assume that "Last saved" refers to the most recent time the scenario was explicitly saved in ETModel. That being the case, we should likely set the preset_scenario_id of the active scenario to point at the saved scenario, and use those values when resetting.

The question is whether "Last saved" needs to be a user-selectable option at all; I think it should just be the default behaviour.

I realize now, I could have been clearer in my description: with 'resetting' I mean hitting this button:

I am adjusting the body of this ticket accordingly.

Okay! So reset the slider to the value stored in the preset/saved scenario, or if no value is present there, back to the default. A big :+1: from me.

I suggest that this should just be the standard behaviour always; and that there's little need for the user to select between "Default" and "Last saved". Preferentially resetting to the preset scenario value is more intuitive.

I'm getting deja vu though, I'm sure we're discussed this before. 😆

Yep, we were discussing the function of the slider reset button in https://github.com/quintel/etmodel/issues/2085

Yep, we were discussing the function of the slider reset button in #2085

That's the one, thanks!

I'm guessing this is a couple of hours to implement and test; there's nothing too complex here.

[dennisquintel]

I think it is worth it. I am busy working on a scenario and I need it every 5 minutes.... :P

It is now fixed so that pressing "reset" next to a slider will use the preset values, rather than the regional defaults. It'll fall back to the defaults if the preset has no appropriate value.

The "Reset scenario" option in the settings menu is not fixed, however. That option starts a new scenario with the same end year and region, and throws everything else away (scenario values and preset_scenario_id included). Resolving that will be more involved and I'm a bit short on time.

I'll leave this issue open as a reminder to do something about the settings menu option, and closed #2085 since that one is specifically about sliders.
