Hello People,
I'm trying to inject JS resources (Dojo testUpdatingChart script) on
the way out from the ObjectDispatchController. I've subclassed
TableForm in a Widget to attach the javascript to. Ultimately, I want
to animate visualisations of generated data coming out of the DB. But
first I wanted to see some Dojo bells and whistles tacked on for wow
factor.
I get the following error:
"TypeError: pic() takes exactly 3 arguments (1 given)"
I guess this kind of error might be as common as ImportError, so may I
present some context. Working from "front to back"...
In /templates I have...
================
<h1>The Plot</h1>
<br/>
<div id="testUpdating" style="width: 300px; height: 300px;">
This text will be replaced by a chart, I hope...
</div>
<!-- Or maybe something like this'll work...-->
<div py:replace="tmpl_context.form(
child_args=dict( fig = dict(id=1,
title='Test Plot',
fig='wijdrgpi4thaerhgoq34itwie'
)
)">Input Form</div>
<!-- Or maybe I've lost The Plot -->
In /widgets I have...
===============
class TestPic(TableForm):
template = "pkg.templates.chart.html"
js = [JSLink(link=url('/public/js/chart.js'))]
class fields(WidgetsList):
id = TextField()
title = TextField()
fig = TextArea()
create_test_pic = TestPic("create_test_pic")
In my controller method in root.py I have ...
================================
@expose("pkg.templates.pic")
def pic(self, title, fig):
tmpl_context.form = create_test_pic
pic = DBSession.query(Pic).filter_by(title=title).one()
pic.fig = fig
return dict(wikipage=pic)
If you hadn't guessed my model has in it...
=================================
class Pic(DeclarativeBase):
__tablename__ = 'pic'
id = Column(Integer, primary_key=True)
title = Column(Text, unique=True)
fig = Column(Text) #gav Column(BLOB) #Ins img here eg. gif, jpg or
png
def __init__(self, title, fig):
self.title = title
self.fig = fig
So the constructor takes 3 args. OK, fine but how do they get passed
in from the front end? Presumably the template <div... fields are
sent in a Pylons/WebOb.request environ thingumajig and ultimately to
my controller. Or do I have to put it in the DB first? If I do, I
get the same kind of error on __init__. I seem to be going in circles
here. Is there some simple, key point about the way TG passes params
that I'm missing? The WebError Traceback seems unhelpful in this
instance but I'll attach it at the end in case it's useful.
