Building an app for booking cars

Hello,

I try to build an app for car booking for my colleagues. We have 3 spare cars that are used for all the company when it's need.

This cars must be book by two fields: date and time of reception and date and time of return the car. If one person book one car , that car cannot be book in that interval... cars can be book for several hours or multiple days...

I don't have clear ideas for start. Maybe someone can give a hint or an idea.

 

Thank you

Hi @ciprianpopovici

Do you want to populate the Combo Box with the CarNumber from another list?

 

You just need to modify as the note says:

If(
    !(DataCardValue8.Selected.CarNumber in //Here you should replace the Value with CarNumber from your collection//
        Filter(
            Actions,
            And(
                DateValue1.SelectedDate + Time(
                    Value(HourValue1.Selected.Value),
                    Value(MinuteValue1.Selected.Value),
                    0
                ) >= ReceptionTime,
                DateValue1.SelectedDate + Time(
                    Value(HourValue1.Selected.Value),
                    Value(MinuteValue1.Selected.Value),
                    0
                ) < ReturnTime
            ) || And(
                DateValue2.SelectedDate + Time(
                    Value(HourValue2.Selected.Value),
                    Value(MinuteValue2.Selected.Value),
                    0
                ) > ReceptionTime,
                DateValue2.SelectedDate + Time(
                    Value(HourValue2.Selected.Value),
                    Value(MinuteValue2.Selected.Value),
                    0
                ) <= ReturnTime
            ) || And(
                DateValue1.SelectedDate + Time(
                    Value(HourValue1.Selected.Value),
                    Value(MinuteValue1.Selected.Value),
                    0
                ) <= ReceptionTime,
                DateValue2.SelectedDate + Time(
                    Value(HourValue2.Selected.Value),
                    Value(MinuteValue2.Selected.Value),
                    0
                ) >= ReturnTime
            )
        ).Car),//Here you should delete the Concat() function//
    SubmitForm(EditForm1),
    Notify(
        "Already reserved!",
        Error
    )
)

Here's a suggestion: before you go through the effort of building an app, why not try the built-in calendar functionality in Microsoft 365? You create a "Resource" for each car, and then it gets its own calendar. If that works for your team, then you're all set. If you need more functionality than that, then consider taking it further with an app.

 

Hope that helps,

Bryan

Hi @ciprianpopovici,

Do you want to create a car booking system?

Could you please share a bit more about your need?

 

Actually, you should prepare a SharePoint list including the Car(Choice), ReceptionTime(Date and time) and ReturnTime(Date and time).

Note that you need to make the Car field Required so that each user must select a car before he create a request.

vqiaqimsft_0-1636617372605.png

You could generate an app directly based on the data source as below:

vqiaqimsft_1-1636617530902.png

Then you could get an app with three different screens:

vqiaqimsft_2-1636617579558.png

Set the OnSelect property of the submit button as below:

If(
    !(DataCardValue8.Selected.Value in Concat(
        Filter(
            Actions,
            And(
                DateValue1.SelectedDate + Time(
                    Value(HourValue1.Selected.Value),
                    Value(MinuteValue1.Selected.Value),
                    0
                ) >= ReceptionTime,
                DateValue1.SelectedDate + Time(
                    Value(HourValue1.Selected.Value),
                    Value(MinuteValue1.Selected.Value),
                    0
                ) < ReturnTime
            ) || And(
                DateValue2.SelectedDate + Time(
                    Value(HourValue2.Selected.Value),
                    Value(MinuteValue2.Selected.Value),
                    0
                ) > ReceptionTime,
                DateValue2.SelectedDate + Time(
                    Value(HourValue2.Selected.Value),
                    Value(MinuteValue2.Selected.Value),
                    0
                ) <= ReturnTime
            ) || And(
                DateValue1.SelectedDate + Time(
                    Value(HourValue1.Selected.Value),
                    Value(MinuteValue1.Selected.Value),
                    0
                ) <= ReceptionTime,
                DateValue2.SelectedDate + Time(
                    Value(HourValue2.Selected.Value),
                    Value(MinuteValue2.Selected.Value),
                    0
                ) >= ReturnTime
            )
        ).Car,
        Car.Value,
        ","
    )),
    SubmitForm(EditForm1),
    Notify(
        "Already reserved!",
        Error
    )
)

Note that the 'Actions' is my data source and the DataCardValue8 represents the Combo Box corresponding to the Car field in your SP list.

DateValue1, HourValue1, MinuteValue1 separately represents the Date Picker and hour picker and minute picker as below:

Here is a demo, you could check the attachment for details.

This is 120% brilliant. I am still struggling to understand the whole thing with the Concat, but it works like a charm 💪

First of all, I would like to congratulate you for the solution. However, I have an observation, when I try to edit the record the message appears: "Already reserved!". What is your suggestion to fix this?

Hello,
thank you very much for your help!
I would like that a vehicle is automatically added to the booking and not the user does it himself.
I have tried the following:

MarcHS_4-1674210706505.png

 

MarcHS_0-1674210420795.png

The vehicle list:

MarcHS_6-1674210911794.png

 

The booking list

MarcHS_5-1674210736941.png

The license plate number (DE: Kennzeichen) from the vehicle list should be selected when the vehicle is free for the particular booking and added to the "License plate number" line.

 

However, the vehicle is selected which is already booked and not which is free. I think this is because of the "=".
If I change it to "<>" then no vehicle is selected. I think it is because of the "LookUp", because it compares only the first elements. Is there another function for this?

Thanks a lot!


Source code:
LookUp(Test.Car; Car.Value = LookUp(Test;
And(
DateValue1.SelectedDate + Time(
Value(HourValue1.Selected.Value);
Value(MinuteValue1.Selected.Value);
0
) >= ReceptionTime;
DateValue1.SelectedDate + Time(
Value(HourValue1.Selected.Value);
Value(MinuteValue1.Selected.Value);
0
) < ReturnTime
) || And(
DateValue2.SelectedDate + Time(
Value(HourValue2.Selected.Value);
Value(MinuteValue2.Selected.Value);
0
) > ReceptionTime;
DateValue2.SelectedDate + Time(
Value(HourValue2.Selected.Value);
Value(MinuteValue2.Selected.Value);
0
) <= ReturnTime
) || And(
DateValue1.SelectedDate + Time(
Value(HourValue1.Selected.Value);
Value(MinuteValue1.Selected.Value);
0
) <= ReceptionTime;
DateValue2.SelectedDate + Time(
Value(HourValue2.Selected.Value);
