Hello, I would like to build upon a previous discussion about creating
a FAQ in web2py:
https://groups.google.com/forum/#!msg/web2py/gzCnwBIlkeM/GJsXi0puHMYJ;context-place=forum/web2py
I like the data model discussed there:
db.define_table('faq',
Field('question','string'),
Field('answer','string'),
Field('arrange','integer')
)
And I completely understand how to unroll it in a view:
{{for faq in db(db.faq).select():}}
{{ =H3(T(faq.question))}}
...
{{=DIV(T(faq.answer))}}
...
{{pass}}
But one thing I do not know how to do completely would be to only
display the questions upon initial page load and then when the
question (or a plus-sign next to the question) is clicked, the answer
is dynamically retrieved and inserted beneath the question. Sort of
like an accordion.
I would like to step through my thinking towards an answer. But I
would appreciate some help when it comes to registering a Javascript
onclick event and rewriting the DOM via a Javascript tag.
The first thing we need to do is to simply render the question and
create a placeholder div for the ajax-loaded answer:
{{for i, faq in enumerate(db(db.faq).select()):}}
{{ =H3(T(faq.question))}}
...
{{=DIV(_id='faq_{0}'.format(i))}}
...
{{pass}}
The controller would look something like this:
def faq():
faq = db.faq(request.args(0, cast=int))
return dict(faq=faq)
And the view/faq.load view would be something like
{{=DIV({{=faq.answer}})}}
But I do not see how to instruct web2py to take a click event on the
FAQ question and pass the faq.id to the controller as a request.args
so that it can retrieve the FAQ and call the .load
component. Furthermore, I dont see how to get the DIV generated in the
load component to replace the specific div that should be replaced in
the view.
