the basic plan is to provide a generic JSONRPC front-end to Django forms which could conceivably become a de-facto interoperability standard for web 2.0 applications to create, validate and store data in "forms".
i've just added "describe" and "describe_errors". http://pyjamas.svn.sourceforge.net/viewvc/pyjamas/trunk/pyjs/jsonrpc/django/jsonrpc.py?view=markup the basic idea, as mentioned previously, is to allow an AJAX application, using JSONRPC, to interact fully with Django Forms. i.e. *without* forcing the server to generate some dumb bit of HTML which you are forced to use, forced to perform HTTP POSTs on etc. etc. now that "describe" has been added, the next step will be to create an http://pyjs.org AJAX form "widget" that uses the "describe" command to find out what fields to build into the form. * CharField, FloatField, DecimalField etc. will result in a pyjamas TextBox, with the option for a TextArea being a user-defined option. * DateField, TimeField etc. will result in a calendar widget popping up, there's one i've found at: http://pyjamas-utils.googlecode.com/svn/trunk/examples/calendar/index.py * FilePathField will be interesting because it implies a level of interaction with the server: the most sensible widget to use here would be a recursive / interactive Tree Widget that performs further JSONRPC function calls to obtain subdirectory contents, on request. exactly what these fields will go in to, and what CSS style names will be attached to them, will be entirely up to the user, with sensible defaults provided. a Grid seems the most sensible, with the names on the left, and fields on the right, springs to mind, resulting in the construction of something similar to the "as_table" method of Django Forms. except pure AJAX. no HTML in sight. interestingly, i can't find anything in Django Forms which tells you how to specify "password" input boxes. also, RegexField's design destroys the possibility for finding out what the regex is (in string form), thus making it very difficult to perform client-side validation (using the ECMAScript Regex object). so there are a few hurdles yet to be overcome. the above can also be implemented in GWT, using exactly the same JSONRPC service, which is why i describe the API as being a de-facto standard. in fact, if you were feeling particularly masochistic (i.e. a PHP programmer) you could implement this in PHP, both client or server. anyone who would like to collaborate or contribute please do join the pyjamas-dev list. l. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Django users" group.
