react wait until state change

as state changes are happening asynchronously, how can I wait until state change is complete and call a function? Note: I am using functional component.

python group multiple

I have the dataset (attached image) contains device and sensor data with a timestamp. I want to generate aggregates for every minute, device and sensor. I tried this expression but it does not help. As there are two devices and three sensors, I should get only 6 records per minute but the expression below returns more than that. Can anyone help fix my code please?

deviceid (S):timestamp (S):datatype (S):value (N)

dealing with async method calls

Raj — Thu, 22 Apr 2021 14:08:04 +0000

newNote is optional and if available should be pushed to notes colleciton via reducer using addProjectNotes function hook. The createProject methods seems called before the addProjectNotes completes execution and Notes collection is always blank. How can I call createProject only after addProjectNotes is fully executed?

'''
if (projectData.newNote) {
addProjectNotes(addNote(projectData.newNote))
}
createProject(projectData, setIsSubmitting, submittedCallback);
'''

mention component

Looking out for a component that supports mentioning users with draftjs component.
Is this https://www.draft-js-plugins.com/plugin/mention the only available?!

react state lost

Raj — Mon, 05 Apr 2021 14:56:48 +0000

Here's the state data structure:
projectData:
{
        projectCode: '',
        projectName: '',
        projectDescription: '',
        clientCode: '',
        clientName: '',
        officeCode: '',
        office: '',
        industryTypeName: '',
        statusName: '',
        statusCode: '',
        projectResources: []
}

Here's the reducer, when this gets executed all the state data is lost except projectResources

case "SET_PROJECTROLE":
            {
                const newResources = [...state.projectData.projectResources];
                newResources[action.payload.Index].ProjectRole = action.payload.ProjectRole;
                return {
                    ...state,
                    projectData:
                    {
                        ...state.projecData,
                        projectResources: [...newResources]
                    }
                };
            }

state hook not a function

Raj — Tue, 22 Dec 2020 07:37:50 +0000

I got stuck on using state hook and keep getting state hook is not a function. Tried restoring all packages and used different syntax not sure what I am missing here. Getting error message setExactPage is not a function. Any help would be appreciated.

const [currentPage, setPrevPage, setNextNext, setExactPage] = useState(0);
const handleFirstProposalPage = () => { setExactPage(1) };

First Page: {currentPage}
First Page

Getting started with reducer...

Raj — Sat, 05 Sep 2020 06:53:01 +0000

Has anyone worked on react with reducers? I am having issue with state management and would appreciate any help.
