create resource crash??

[skydig]

I create resource using create_resource function, which depend on a signal, because the resource can be updated in future,
the signal triggered in create_effect, the crash is as following.
I think the crash happened in page load phase。

rfid_mgt-client-f545b6d0f3d7e6e3.js:663 panicked at .cargo\registry\src\rsproxy.cn-0dccff568467c15b\leptos_reactive-0.6.12\src\runtime.rs:840:30:

[gbj]

It is not really possible to help without a reproducible example. Could you show what you are doing that leads to this error?

[skydig]

hard to provide example, but the flow is like following, I want to know the coding is correct or not?
I have a fetch_asset_action,

<button>
  // here, set a signal for a effect  which get the signal and the **fetch_asset_action** is dispatched in the effect.
</button>

view is like following:

view! {
  ..... other view
  { move || 
          {
            let ret = fetch_asset_action.value().get();
            if ret.is_some() {
                   //do some calculation here.
                   //then return a view (into_view)  for showing
            } 
         }
  }//move  
 ...... other view
}//view

click button, then crash...., but the data returned by fetch_asset_action still can be shown,
the flow is correct?

very thanks.

[skydig]

Thanks,
code like following, I have found something

 let LOCS = create_resource(move|| load_location_page.get(), move |(page,random)|async move {
	...
	(location_data,total_page)		
 });
 view! {
	{move || match LOCS.get() {
		None=> view! { <p>"reading...."</p> }.into_view(),
		Some((location_data,total_page)) => {  
							
				view! {
					<TableBody>
					  <For
						each=move || location_data.clone()
						key=move |loc:&Location| loc.id
						children=move |loc| view! {
						  <TableRow>										
							<TableCell>{loc.name.clone()}</TableCell>  
							<TableCell>
								<Button  class="h-6" color=ButtonColor::Info on_press=move |evt| {									 
									set_is_add_show.set(false);
									set_is_modify_show.set(true);
								      }
								>"modify"</Button>
							</TableCell>
						  </TableRow>							
						>
					</TableBody>
				        <Button  class="h-6" color=ButtonColor::Info on_press=move |evt| {						 
									set_is_add_show.set(true)
									set_is_modify_show.set(false);
				          }>"add"</Button>
								
				  }.into_view()
			    },
			}
		} 
	}
	{move || {
			if is_add_show().get() {
				view!{
				...
				}
			}
			else if modify_show.get() {
				view!{
				...
				}
			} else {
				view!{}.into_view()
			}
		}
	}
}

when

{move || {
			if is_add_show().get() {
				view!{
				...
				}
			}
			else if modify_show.get() {
				view!{
				...
				}
			} else {
				view!{}.into_view()
			}
		}
	}

is removed
crash disappear. so the reason is ?

[gbj]

Are you using server-side rendering? Do you get a warning in the browser console about reading from a resource outside Suspense?

You say the crash happens on page load — Later you say that it happens when you click the button. Which is it?

[skydig]

I use CSR + tauri + leptonic

crash both when button click and page load,but seems no side-effect?

following code, I change to show all these two views( but with condition) ，crash disappear...

{move || {
			if is_add_show().get() {
				view!{
				...
				}
			}
			else if modify_show.get() {
				view!{
				...
				}
			} else {
				view!{}.into_view()
			}
		}
	}

change to

{
  move || {
          view! {
          <div style:display=move||{if is_add_show.get()==true {""}else{"none"}}>
           。。。
          </div>
         }.into_view()
  }
}
{
  move {
          view! {
          <div style:display=move||{if is_modify_show.get()==true {""}else{"none"}}>
           。。。
          </div>
         }.into_view()
  }
}


 

[skydig]

and I use leptos 0.6.12

I'm sorry, I can't follow along with what's happening. If you can provide a minimal, reproducible example (i.e., something that compiles and that I can run) I can look at it more.
