Adding new data to data source using a form

[Samurai89]

Hello again,

I'm trying to create a form to add new employee work hours to an existing Excel data source. The data source (EmployeeDetails) has the following columns:

Data source: EmployeeDetails

I want a form that allows me to enter all this information at once for one employee, that is, select the month from a drop-down list, select the employee from a drop-down list, and enter the value for each category (Lunch, Meetings, Work, Travel, Breaks) in separate fields, etc. 

ScreenNewHours

I'm using different data sources to populate the MonthYear drop-down (DropdownMonthYear) and Employee drop-down (DropdownEmployee) and the Category information:

Data source: MonthsDataData source: EmployeeTableData source: CategoryTable

Basically, the form should let you select the MonthYear from a drop-down list, the Employee from a drop-down list (these work), to display each category and allow you to enter a value for each category, and at the end submit this all to the EmployeeDetails data source. Is this possible? Is it possible to add information from one data source to another data source?

Any help/advice would be appreciated!

Hi @Samurai89,

There is no problem using multiple data sources to enter information into one table.  As long as you are only adding new records to your spreadsheet,  you can achieve your goal by using the Collect() function. (You would use a different function if you were editing data already in the table.)  Also, I would leave as little chance of the user entering text as possible, so for inputting data into the Category column, I would use a Dropdown control or Radio control with the Items property set to ["Lunch","Meetings","Work","Travel","Breaks"]. For the numeric entries, you might want to consider using a Slider control.  I've been burned in the past by user's entering data in unpredictable ways, like putting text in an Inputbox when a number is expected. 

Your Save button would have as it's OnSelect() property

Collect(EmployeeDetails, {ID: First(Sort(EmployeeDetails, ID, Descending)).ID+1, Employee: DropdownEmployee.Selected.Value, MonthYear: DropdownMonthYear.Selected.Value,
 Category: Radio1.Selected.Value, LeaveDays: DataCardKeyLeaveDays.Value, TotalHours: DataCardKeyTotalHours.Value, etc.})

In order for the Collect() function to work properly, The column names in the collect function must be identical to the column names in the data source.   The ID is entered using a calculation and would be invisible to the user. I like using First(Sort(Descending  instead of Max() or Last() because the latter are not delegatable and if the table grows to over 2000 records, those functions will not be correct while First(Sort(Descending  will work for very large tables. 

You could make sure that all required fields are entered by using the DisplayMode of the Save button to disable it until data was entered.  So if LeaveDays and TotalHours were required fields, the DisplayMode property of the button would be

If(!IsBlank(DataCardKeyTotalHours) && !IsBlank(DataCardKeyLeaveDays), DisplayMode.Edit, DisplayMode.Disabled)

This information is really great, however, how can I enter data for all the categories at the same time and save it to the data source at once?

I've applied these formulas as you suggested, however, I'm getting the following error:

Incompatible type: The 'DaysAtWork' column in the data source you're updating expects a 'Number' type and you are using a 'Error' type. 
The function 'Collect' has some invalid arguments.

 I get the same error for all the values, except the MonthYear and Employee drop-downs (Employee : DropdownEmployee.Selected.Employee and MonthYear : DropdownMonthYear.Selected.MonthYear).

I've checked the data source and these columns are all formatted as 'Number' type.

Try this please. Start with a new screen and put fresh controls on it. Use the same formula for the save button but reference the new controls. Try it with one or two controls and if it works, add more. I’m unot sure what is wrong with your current form but rather than try to figure it out, I would start fresh.

Ok, so I did what you suggested and created a new screen. I had to change the OnSelect to:

Collect(EmployeeDetails,{ID: First(Sort(EmployeeDetails,ID,Descending)).ID+1, 
Employee: DropdownEmployee.Selected.Employee, MonthYear: DropdownMonthYear.Selected.MonthYear,
LeaveDays: Value(DataCardKeyLeaveDays.Text), TotalHours: Value(DataCardKeyTotalHours.Text)})

It kept showing errors for the DataCardKey values, so I figured out how to format them as values (based on the data card's default 'Update' value). Now it does not show any errors. However, I still need to find a way to add a value for each category and then save all this data at once. Any ideas? Is it possible to add a text input box for each category?

Hi @Samurai89,

I am not sure what you mean by saving a record all at once.  Are you keeping the same record in different tables?  If so, this is a poor database design.  If one record can have many categories, and one category can have many records you are dealing with a Many-to-Many relationship and you will need to set up a junction table to handle it.

@Drrickryp I mean I would like to add a value for each category (Lunch, Meetings, Work, Travel, and Breaks), and every other column in this table: 

Data source: EmployeeDetailsThe part I'm struggling with is adding a value for each category (Lunch, Meetings, Work, Travel, and Breaks) on the same form. I've also put the categories in a separate data source if that helps - CategoryTable:

Data source: CategoryTable

So far I've managed to add a value for all the other columns:

• Add a value for TotalHours (Completed)
• Add a value for DaysAtWork (Completed)
• Add a value for LeaveDays (Completed)
• etc.

The main goal is to save all these values at once to the same data source (EmployeeDetails). 

How do I set it up to allow me to add a value for Lunch, Meetings, Work, Travel, and Breaks on the same form?

Hi @Samurai89,

I was examining your data source table and in order to properly normalize it, I came up with the following tables.

 The MonthYear and and MonthID can be calculated from the daterecorded and the total hrs worked can be calculated from the Sum(HoursSpent) so they don't need to be included in the underlying tables.

@Drrickryp I'm not sure I follow. Should I create/use a database file?
