create form-record using crud

[rac]

hello,
how to create new form record using crud? I need prepopulate form-record
before redirecting user to fill it.
There is 'put' method that can do this, but it requires complete form-record
data to be send. I need sth like: create new form record, retrieve initial
xml from it, modify it and save it back. Then create url + id of that new
form record and redirect user there to fill it.
thanks,
Radek

Hi Radek,

I'm afraid currently we don't have an API that does all those steps. You'll need to:

1. Do a GET against CRUD API to retrieve the form definition, from which you can extract an empty "template" document.

2. Choose an ID for your new instance. If you can call Orbeon Forms' code, you can use SecureUtils.randomHexId().

3. Do a PUT against the CRUD API to store the document.

when i request form definition (/orbeon/fr/service/persistence/form/app1/f1),
I get only:

<forms>
<form operations="*">
<application-name>app1</application-name>
<form-name>f1</form-name>
<title xml:lang="en">Untitled Form</title>
<description xml:lang="en"/>
<singleton>false</singleton>
<last-modified-time>2016-09-06T08:56:17.969Z</last-modified-time>
</form>
</forms>

am I using right method for retrieving form definition?
I found it here:
https://doc.orbeon.com/form-runner/api/persistence/

On the other hand i also found:
"On the other hand, when Form Builder publishes a form definition, it stores
it where Form Runner will find it, that is under:
/crud/[APPLICATION_NAME]/[FORM_NAME]/form"

but /orbeon/crud/app1/f1/form
returns "Orbeon Forms - Page Not Found".

thank you,
Radek

Hi Radek,

/fr/service/persistence/form is what is referred to as the "Form Metadata"
API. It only returns some information about the form, or forms. You can
think of it as the API you'll want to call if you want to get a list of
published forms, for instance to create a page showing users what forms are
available to them. E.g. this is the API used by the Form Runner home page.

https://doc.orbeon.com/form-runner/api/persistence/forms-metadata.html

To retrieve a full form definition, you should use the CRUD API, e.g.:

/fr/service/persistence/crud/acme/demo/form/form.xhtml

More on this at:

hello,
It works, with small exception related to orbeon 4.8 'iteration' elements,
like here:

version found in prototype inside form-definition:
<repeated-contact>
<repeated-contact-iteration>
<repeated-email>te...@a.com</repeated-email>
<repeated-phone>p1</repeated-phone>
</repeated-contact-iteration>
<repeated-contact-iteration>
<repeated-phone>p2</repeated-phone>
<repeated-email>te...@a.com</repeated-email>
</repeated-contact-iteration>
</repeated-contact>

vs version expected by form-record:
<repeated-contact>
<repeated-email>te...@a.com</repeated-email>
<repeated-phone>p1</repeated-phone>
</repeated-contact>
<repeated-contact>
<repeated-phone>p2</repeated-phone>
<repeated-email>te...@a.com</repeated-email>
</repeated-contact>

What is most simple way to synchronize them?
Can I say somehow "data-format-version=edge" when putting new form record,
or is there any other way to make runner accept iteration element?
Are there other differences between prototype stored in form-definition and
form-record?
thank you,
Radek

Hi Radek,

Are you saying that you'd like the CRUD API to convert data from the "4.0"
format (without the -iteration elements) to the "edge format" (with the
-iterations elements)? Or that you'd like data to be stored in the "edge"
format in the database?

Scenario is following:
I retrieved form definition and extracted prototype of form record from it.
I used 'put' and used above data as body param.
I opened in orbeon ui newly created form record.
Result is that eveything except 'iteration' elements work (because prototype
in form-definition has different schema than 'put' method expects).

I hope to have one universal method for creating form-record that would work
with every form (I guess orbeon has sth like that in its internals, would be
nice to have it as crud method.).
thank you,
Radek

Hi Radek,

Yes indeed, there is code in Orbeon Forms that removes those elements, and adds them, as necessary, but it isn't exposed as an API right now. I imagine that the PUT could support being told about the data-format-version, either as a request parameter or HTTP header, and if set to "edge", remove the "iteration elements". For now, I've created an RFE for this:

https://github.com/orbeon/orbeon-forms/issues/2938

(If this is a blocker for you, and if your organization has a subscription with us, I'd recommend you contact us to see how this could be developed as a sponsored feature.)
