[web2py] Re: Using web2py's view/template engine in a standalone application
For future reference, this has been resolved with revision
a1619d2857e5 in the mercurial repository.
As mentioned before, simply include just the gluon/template.py file
from web2py, then use it similar to the following example.
example.py
~
from template import render
renderedText = render(
filename='/path/to/view.html',
context=dict( foo=bar )
)
~
View content is usually escaped, but if you run it standalone, you can
break out of escaping with the helper NOESCAPE().
Here's an example:
view.html
~
html
body
{{= NOESCAPE( foo ) }}
/body
/html
~
Thanks for everyone's help on this!

Yes..
You need some sort of response class that has a .write method... this
can
be
a hacked up cStringIO or other.
Alternatively you can perform the same thing manually by passing in
writer,
which instead of the template engine writing ``response.write(%s)`` it
could write whatever you want as a callable function.
So for example, say you defined your ``CustomResponse`` class as earlier
in
the list...
context['response'] = CustomReponse()
exec(parse_template(...)) in context
print context['response'].body.getvalue()
SO yeah... in the end if we implemented your suggestion of overriding
the
response class on import, then the render function would work as
expected.

Although it looks like pandoc(str(inFile)) might be the culprit from

everything works fine, so I doubt that this is the cause.

Re: [web2py] Re: Using web2py's view/template engine in a standalone application
If you could, let me try and get my solution to work.
When I'm done, should I post a patch here in the group or should I
email it directly to you?

You need some sort of response class that has a .write method... this
can be
a hacked up cStringIO or other.
Alternatively you can perform the same thing manually by passing in
writer,
which instead of the template engine writing ``response.write(%s)`` it
could write whatever you want as a callable function.
So for example, say you defined your ``CustomResponse`` class as earlier
in
the list...
context['response'] = CustomReponse()
exec(parse_template(...)) in context
print context['response'].body.getvalue()
SO yeah... in the end if we implemented your suggestion of overriding
the
response class on import, then the render function would work as
expected.
