I have the following function in a module - this function performs a
Regex search and attempts to replace matches with a link (generated
with the A() helper). The regex and replacement is working correctly -
if I change the value of the replace variable to something other than
the A() helper, it works as I expect. Something with the A() helper is
causing the return to not have the link at all (just the innerHTML
from the link).
The module's function:
def link_wiki_tags(content, db, request):
import re
from gluon.html import A, URL
pattern = re.compile('\[\[([\w\s:]+)\]\]')
for match in pattern.findall(content):
slug = slugify(match)
if db(db.games.slug == slug).select():
replace = A(match, _href = URL(r = request, c =
'games', f =
'view', args = slug), _title = match)
elif db(db.people.slug == slug).select():
replace = A(match, _href = URL(r = request, c =
'people', f =
'view', args = slug), _title = match)
elif db(db.companies.slug == slug).select():
replace = A(match, _href = URL(r = request, c =
'companies', f =
'view', args = slug), _title = match)
else:
replace = match
content = re.sub('\[\[' + match + '\]\]', replace, content)
return content
How this module is called from the view:
{{= link_wiki_tags(person.content, db, request) }}
Sample Input:
[[John Carmack]] is a developer for [[Quake Live]].
Expected Output:
<a href="/shooterhero/people/view/john-carmack" title="John
Carmack">John Carmack</a> is a developer for <a href="/shooterhero/
games/view/quake-live" title="Quake Live">Quake Live</a>.
Actual Output:
John Carmack is a developer for Quake Live.
As I mentioned, if I change the replace lines within the conditional
checking for a database result, it will change the output as expected.
I have change this replace variable to a string, as well as the URL()
helper, both of which worked fine. In other words, I have narrowed
this issue down to the A() helper.
Any help in getting the module's function to return the intended
output would be appreciated. Is there some sort of filtering placed on
module function returns (something that would strip out tags).
