Hi,
When creating templates I typically have 3 separate parts (header,
body, footer) which I combine to pass a singe string to the web-server
(CherryPy in this case).
My first approach is as follows...
from jinja2 import Environment, FileSystemLoader
env = Environment(loader=FileSystemLoader(''))
tmpl = env.get_template('Body.html')
page_body = tmpl.render()
tmpl = env.get_template('Header.html')
page_header = tmpl.render()
tmpl = env.get_template('Footer.html')
page_footer = tmpl.render()
page_code = page_header + page_body + page_footer
but this contains repetitious code, so my next approach is...
def render_template(html_file):
from jinja2 import Environment, FileSystemLoader
env = Environment(loader=FileSystemLoader(''))
tmpl = env.get_template(html_file)
return tmpl.render()
page_header = render_template('Header.html')
page_body = render_template('Body.html')
page_footer = render_template('Footer.html)
However, this means that each part is created in its own environment -
can that be a problem? Are there any other downsides to this
approach?
I have chosen the 3-part approach over the child-template approach
because I think it may be more flexible (and easier to follow), but I
might be wrong. Anyone like to convince me that using header, body
and footer blocks might be better?
Any advice would be appreciated.
Alan
