Merge lp:~cprov/uci-engine/webui-create-ticket into lp:uci-engine

[Celso Providelo]

Implements a ticket creation form in the webui.

Implements a ticket creation form in the webui.

This form will be used during the ci-train transition (where the CLI is not part of the workflow).

It uses Y.form to build, render and validate the new form and implements a custom form submission function to submit data as JSON to the Ticket-System.

The form is not yet linked from the other pages, the current navbar/breadcrumb is not a good place for it (IMHO).

Comments inline. Are we going to handle form validation in a follow up MP?

Basic validation were already in place (required fields). I've added
an email-address validation for the current owner field for now, but
once authentication is in place that field will be removed/hidden.

> Title, description, and owner end up as clickable links that focus on the title input box. Series is plain text. This looks odd.

I've extended and fixed Y.SelectField() which was being stupid when
rendering the label.

I've split the 'webuiform' module as an experiment, overall loading
performance is faster. 'webuiforms' also host 'seriesChoices', so it's
easier to maintain the hardcoded bits until there is a better
solution.

I thought we were going to have the TS generate the form?

[Celso Providelo (cprov)]

Joe,

I've experimented with this idea and realize that the form generation
is not part of the API provider, it already offer us REST primitives
and it is good at it.

The forms are related to the way the UI is layed and users want to use
it, a single form will probably involve data from many models and will
be executed via multiple REST posts.

Long story short, building forms on TS would be going in the wrong
direction by artificially coupling UI to Models (not APIs), to not
mention the additional django view + forms which would tie us even
more to django for a simple REST wsgi app.

The way it's is done, the form is built and validated client-side in
terms of the information users want to provide and submitted according
to what our API allows us to do.

Do you see it differently ?

If having the TS generate the forms is not optimal then I'm fine with
that. Are we able to utilize the API schema on the client-side so that
the TS can communicate its data requirements?

[Celso Providelo (cprov)]

Joe,

Tastypie allows shallow schema introspection via <API>/schema (e.g /api/v1/ticket/schema/) but it doesn't look very appealing atm (lack of documentation on the model/field level and not precise information for validation since we have many CharFields).

I can try to investigate some good way for using it, but the benefits get quickly consumed when we have to compose forms for multiple models.

No worries. We can sort it out later on. I'm okay with your approach
here.
