Manage relations problems

Hi
I went thru this before. But I cant find the post. Maybe its in the old forum.

I'm trying to do a simple database join with the Manage relational table. But I cant figure it out ...

I have one table for Courses. course_id and coursename.
One table for course dates. coursdate_id and dates.
One relational table with course_id and coursedate_id

Now in the Updatepage for the Course records. I try to insert the MRT behavior.
But it does not insert anything in the relations table.

In my old functioning page I have a recordset "RecordsetWADADynList" that I dont know how to get there in this new version.
If I insert a regular recordset to bind to the select list. The update page is blank in the browser.

I have tried with both select list and repeating checkboxes. But nothing happens.

Can someone provide the steps to have this functioning.

A year back or so when I was trying this. You promised an udated tutorial on this. What happend to that?

regards
olle

I have done a bit of testing on the Manage Relational Table server behavior and can confirm it to be working as expected.

Here is the basic idea of how to use this server behavior.

1
Start on an insert or update page. You will first need to add a new recordset to your page to select the records from your secondary table, for example if you were configuring product options you would have a recoredset select all the records from your options table that you would like to associate with this product.

2
Once the recordset is in place on the page you will need to add the input to record the values of this secondary table. In regards to the example above you can add in a checkbox.

3
Next you will need to associate this new input with your new recordset. For the value you can bind the id from the new recordset, and for the label you can just use whatever value from the recodset would best reflect that record.

4
The next thing to go is to apply the repeat region server behavior to this new input and the label for it. In the repeat region server behavior make sure to choose your new recorset and let it display all records.

5
The final part is to add in the Manager Relational Table server behavior. When you add this server behavior you will fist need to specify the trigger and the relational table. For the trigger you can just use the button insert/update pressed. For the table make sure to select your relational table. Make sure you select the redirect page on this step.
On the next step you will select which column in your relational table will hold the id from your main table, you also need to select what type of data this will be and use the lightning bolt icon to select the id value that will be inserted here, it should be the id for the just inserted record held in the session varialble for an insert page and the id from the product recordset for an update page.

In the step after this you will select the column in the relational table that will hold the secondary table's id, like the previous step you will need to select the data type, for the value it should be defaulted to your repeat region input.

In step 4 of 4 you can set the value of the id or other columns in this table, if you have an auto incrementing id then you do not need to set a value for this column. You can finish it now to add the Manage Relational Table server behavior into your page.

When you test the page out you should see your newly added repeat region with the values from the recordset displayed. When you select these values and insert or update it should update your relational table.

Hi.
The problem is solved.
I did not mean Manage Relational table behaviour was not functioning. I just did not remember how to use it.

I managed to look at the files that comes with Data assist. And figure out how it's done.

But a year ago or so You promised to update the tutorial for Data assisst to include the Manage Relational table.

It's the Blue Sky music Tutorial. And for instance the items_Update.php file that contains the behaviour. But i't is not anything in the documentation about that.

Regards
Olle

We try not to make any promises we can't keep. I promise I'll forward this suggestion to the documentation team. I can't promise how, if, or when they may act on it.
