Hello,following was originally asked by Bart Lateur on (i guess) the same list. I could not find a solution to his problem. The reason I reproduced his exact question here, is because i have the same problem.
In addition can i have the config data coming from the database too, rather than a yaml (or xml) file? all the examples i saw were in the context of a webApp. someone please advice. thank you. Rajeev Bart sorry to reproduce your question here, hope you dont mind. [html-formfu] I need the most basic tutorial Bart Lateur Wed, 12 May 2010 01:16:55 -0700 Though I've worked with similar modules in the past, I find it very hard to wrap my head around the very basics behind HTML::FormFu. Even the tutorials I can find on the web (either by external authors, or included with the module on CPAN) start at a too high level. What I want is a very basic example on how to make a basic CRUD interface, in a minimal CGI app. I want to do the next thing, *without* use of *any* external module: no DBIx::Class, no Class::DBI, and definitely no Catalyst! I want to learn exactly how FormFu is supposed to work without all this extra bagage. * Data from database: the interface to the DB is external %data = ( id => 1234, foo => "one", bar => "two", yn => 1 ); * Basic form: auto_fieldset: 1 elements: - type: Hidden name: id - type: Text label: "Foo:" name: foo - type: Text label: "Bar:" name: bar - type: Checkbox label: "boolean:" name: yn default: 0 - type: Submit value: "Update" I'd like to use the same form script for showing the data to the user and for getting the new values from the user. Business as usual, I would say. My questions: * How do I put the data from the hash \%data into the form? Should I use default_values for that? Or something else? process? * I assume I must "process" the input to put the updated data into the form? * Apparently a partially updated form drops every default value? Is that correct behaviour? * How do I get the data back out of the processed form, in order to update the DB? I'm especially worried about that boolean * How do I replace the Checkbox with a pair of radio buttons? Just replacing "Checkbox" with "Radio" produces an unusable result, and the docs for HTML::FormFu::Element::Checkbox are useless. * How does basic validation fit in? How do I flag an error, for example if text in a field is too long, or contains illegal characters? * Where does validation in Javascript, i.e; without round trip to the server, fit in? * What's the best way to have a single form for both "add" and "edit", depending on whether "id" is set or not? * How do you change the way items of the form are rendered, for example, what if I prefer the form to be in a 2 column table, labels in column 1, fields in column 2? * What's the best practice to flag to a user a field is required? How does it fit into FormFu? There's probably more, but nothing I can think of right now... Thank you for you're patients.
