Delete Option not Working [message #503610]

Hi,

It is a Students Leave Application form.
Each Student leave application history is maintained.
So One Student has multiple records.

I have Two Blocks. Main Block and Dummy Block.
Main Block is used to enter the Students data.
Dummy Block is used to display the Students data.

When I give Student ID in Main Block and press enter,
It displays previous data in Dummy block.
The Cursor is in the Second field
of the Main Block where we fill the Students Data.
Then the Data is saved and displayed in Dummy block.

When I want to Delete a Record, The Option remove record is
not working in this form.
I write code in key-Delrec trigger also
delete_record;
clear_form;
commit;

But the record is not deleted it remains in database.
When deleting a record Data must be in Main Block.
But the Main block is empty initially.
I don't know what to do to delete a record.

Fields in Main block : Student ID, Name,Noofdays,datefrom,
dateto,official.
Dummy block contains same fields and
displays the student past data.

Please help in solving this delete record issue.

Thanks and Regards,
Shanie

Are the two blocks database blocks?
From which block are you trying to delete data?
What level is the key-delrec trigger defined at - form or block?
When you press the delete button do you get an error message?

Did you consider deleting a record without clearing the form (and then committing)? How about

delete_record;
commit;

Hi,

Main Block is Database Block where data is going to Database.
Dummy Block is where data is retrieved from the database
From Main Block I try to delete the record.
Because Dummy is only used to display the data.
I gave at Form level.
After removing record when I press Save button
It gives messages like
Invalid ID Select Active ID from the list.
Then After save option dialog box.
then Application closes.

I tried using Enter Query and Execute Query Option
I gave Student ID and Date From fields and
Data is fetched in Main Block.
I press Remove record Option.
"Before Clicking Save I enter different data in
Main Block and then press Save button.
I can able to delete record but
at the same time new record is also entered.
If I remove record without filling main block then
same above messages are coming and closing the form.

Please Help.

Thanks & Regards,
Shanie

That's not a form builder error message.
So there must be some code in form causing it.
Find it and tell us what trigger it's in.

You do realise that delete_record will only work if you query the record you want to delete first?

Yes I agree and I'm doing that only
but it didnt happening.

Exception is thrown as soon as I press Save button
after removing record which is found
through enter query in Main Block.

If I remove exception then No data found error
is coming.

Please sort this problem.

Wrap the code in the post-text-item trigger in an IF statement that checks that GZAOFFE_STU_ID is not null.

Or better yet change the post-text-item into a when-validate-item since I'm pretty sure that's what it should be.

Its working in When validate item trigger
But there are Mandatory fields which cannot
be left blank like Student ID, Noofdays,Datefrom
which is mentioned in Pre-Commit trigger at form level.

If I disable this then it is working fine
other wise error coming student ID cannot be left blank.

Any Alternate solution to this validation!

Validation should only ever be done in validate triggers.
So move those checks to when-validate-record.
Or just set the required property on the items instead.
I never use pre-commit for anything.

Hi,

I thank you very much for your kind help.

Checks still gave errors when I moved to
when-validate-record or set required property to yes.
But later I moved those checks to key-commit trigger.
Now It is working well.

Is this fine to move checks in key-commit trigger?

Probably not. It might happen that your user will try to exit the form, get the "Do you want to save changes?" message, answer "Yes" and - changes will be saved, but KEY-COMMIT won't be executed.

Saying that WHEN-VALIDATE-RECORD caused errors is not very descriptive. What code did you put in there? What errors did you get?

End if;

end;

When I enter student ID and Pressing enter
It is giving error message
"Student ID, No of days & Date from cannot be left Blank"

I think you never answered: did you remove CLEAR_FORM from the KEY-DELREC trigger? What happened?

As you use Forms 10g: it offers running a form in debug mode. Did you try it? It makes all system (and your own) variables visible, so you'd know what is happening, which triggers are firing so - you might find what is bothering you.

If nothing helps, perhaps you could provide a simple test case (CREATE TABLE and INSERT INTO several records of sample data) and attach your form, so that we could take a look?

Delete should not cause when-validate-record to fire.
Check the form_status, block_status and record_status before the delete_record.
Run the form in debug mode to check what triggers are firing.

It is form which is attached in server.
I compile in Unix and place fmx server.

I don't know how to run in Debug mode for this scenario.

We don't run by clicking
on "Run form" or "Run form Debug" from client machine.
Server link is there where we run in browser.

However, we can see compiling log file.

Please sort out this issue.

Is there anything actually stopping you running the form in debug mode direct from form builder?
If there really is then you'll just have to put messages in every trigger to work out what's going on.

Actually we cannot compile or run
from form builder, If we do
It gives so many errors.

Could you explain briefly about giving messages
in every trigger.

I mean what exactly I have to do?

Put a message in every trigger that displays the name of the trigger.
Also put messages in the delete button before the delete_record command to display the three statuses I mentioned above.

But before that you really should fix the issue with being unable to compile forms in form builder, you can't possibly work efficiently without it.

Delete record is going smoothly when
I gave when-validate-record at Block Level.
Previously I was giving at Form Level.

When Inserting a new record If I leave mandatory field empty,
then Message dialog box displays 'cannot be left empty'
It is not allowing me to do any thing nor closing the application.
When I click 'OK' It is coming again and again.

In When-validate-record Trigger for Checks after message
"raise Form_trigger_failure" is given.

If I remove this then record will be Inserted.

Please suggest any alternate handler to this issue.

Shanie

If you want to get rid of a new record without inserting it use clear record.

Please stop raising your topic, it is counter-productive.
For myself, I will not have a look at it just because of this behaviour.

I think that this has gone too far, and (unfortunately) I don't see the light at the end of a tunnel.

The fact is: Forms Builder's "Data Block Wizard" will create both master and detail blocks, relationship between two of them, create all necessary triggers and procedures that will make a form perfectly OK, as far as the default behaviour is concerned. It means that you'll be able to insert records into a table, query existing records, update and delete them. No further coding from your side is necessary.

Now: I have no idea what you were doing in order to spoil those functionalities, but - perhaps you should simply throw existing form away and create a brand new one. Let Wizard do the dirty job. Make sure the form works OK. Then make it fancy, if you want (and know how).
