posibilities with lenya
Hi,
I am a Lenya/Cocoon newbie who needs to assess the suitability of using
Lenya for a new project.
From what I have read I understand that it is possible to create forms
to capture/validate/store user input using cocoon. Right?
Also, is it possible to use the inbuilt Lucine to
a. perform search on various fields (ie advanced search)
b. look through(create index on) xml documents which are not generated
using lenya(ie are not necessarily a part of the site)?
Finally .. is it possible to dynamically modify menus based on what
files currently exist in a directory? Is there a nice way of doing this
with Lenya or would I just need to write an external program that takes
care of this?
Sorry if the answers to these questions are basic/obvious, but I am just
working on getting my head around Lenya and its limitations.
Thank you muchly,
Vica

the lenya forms are primarily meant for editing content. your usecase
sounds like you may want to use CForms:

sitemap.xmap, and the map:generate and xinclude parts specifically

While poking around, I just discovered that Cocoon has a similar
component built-in... just not well-documented.

Right...
You're correct that you'd be dealing with the "Cocoon" layer there
rather than the Lenya layer (but see below). Cocoon has a good forms
framework (http://cocoon.apache.org/2.1/userdocs/forms/index.html)
> Typically I would be using JSP technology for this kind of form.
Part of the reason Cocoon exists is so that you don't have to use JSP
:-). If you use the Cocoon forms framework, that will give you a
gentle introduction to "flowscript"
(http://cocoon.apache.org/2.1/userdocs/forms/index.html). Flowscript
is server-side Javascript augmented with web continuations, and it's
the controller language used in most Cocoon applications. Unlike JSP,
flowscript is not embedded in page source markup.
What you are describing is not hard to do using the Cocoon forms +
flowscript combination.

sender component... very easy to use.

Basically I need to create a form to capture input from a user of the
live website.
Eg. To make a form for a user to enter their interest in a product and
allow them to select the product depending on the files that exist in a
directory (ie an xml file would correspond to a product). Their
response would then be stored in a file and an email would be sent.
Typically I would be using JSP technology for this kind of form.

Thank you for your help :)

Lenya allows you to easily create web Forms. You define the fields
with many native validation rules. You can choose from several
standard layouts, even mixing them on one form. Setting values for
the fields and saving the results is handled with JavaScript. You can
bypass the standard methods by pulling the form from somewhere else,
or by setting the FORM ACTION to send the page to another system (but
I cannot think of a reason for doing that.)

Yes, there is an example in the documentation that filters using the
language field. Other fields can be added easily.

The default configuration is to crawl a website and create the index
from the results, so many websites can be added to a single index.
(Web pages do not have standard fields, so this may be difficult to
combine with your field-specific search.)

can you be more specific? there are various editors to edit documents
against an xml schema, indeed.

yes, with customization

yes, with the crawler

yes. you probably would use the directory generator for this. take a
look at the blog publication for samples of this
