Subform

[marcvander]

Hey,

i'm migrating all my forms and objects from v3 to v4. The subform logic has kind of changed from v3 to v4 and I cannot make it work anymore.

I have companies in a table called "entreprise" with "entreprise_id" as the primary key. I have contact in a table called "contact" with "contact_id" as the primary key, and a contact can belong to a company, so it has "contact_entreprise_id" as a foreign key of "entreprise_id".

I'm trying to show all the contacts who work in a company. So when on the company form, I'm trying to show in a subform all the contacts of this company. In the v3 it worked:

Now I'm trying to do the same in v4. First the subform object:

Then the form itself which will be displayed as the subform:

And the error I get when accessing the company form:

Any idea on how to do it?

marcvander,

You are right, 3 and 4 work differently - especially when it comes to Subforms.

The simplest way I can think of explaining the differences is...

In version 4 a Subform...
- Is created from a Form - (so things like the SQL and the Primary Key, are defined automatically by choosing a predefined Form).
- Can only be based on a single table (not a query with joins). - Although you could use a View.

I hope that helps.

There's another thread with this "Uncaught TypeError: Cannot read property 'id' of undefined" issue.

A user came up with this solution:

It should all be fixed now.

Please get the latest from Github and let me know.
