Ah, right, I saw right now that it imports the module itself not using
from form.
Probably the most pythonic way to solve the issue is change the jinja
filters setup to care about __all__, in the mean time you can simply
write your jinja filters inside something like jinja_filters_impl.py
and then just do from jinja_filter_impl import whatyouwant into
.lib.templatetools.jinja_filters
All other jinja filters configuration is done by defining a dict :
base_config.jinja_filters = {'my_filter': my_filter,
'other_filter_function': other_filter_function}
so having to define a jinja_filters dict in templatetools.py (or
templatetools.__init__.py) does not seem to be a bad idea to me.
Much simpler than the current solution (so I would say more pythonic ;-) )
Is the templatetools directory supposed to contain something else than
jinja_filters.py (AND __init__.py or it doesn't work !) ?

No, I tried this... It does nothing but adding one more filter '__all__' to
the filters' list. The __dict__ of an imported module containes all the
definitions, imported modules, etc.

I'm not actually sure, but shouldn't defining __all__ inside your
jinja_filter.py solve the issue?

Hello,
I want to add a custom filter to jinja2 and I found that there is a way
to
do that through adding a .lib.templatetools.jinja_filters.py module, so I
tryed it...
Every function defined in this module become a filter. But not only
functions :-(, everything imported in this module is included in the
filter's dict !
I'm not sure this was the expected behavior.
Could not it be a .lib.templatetools.py that would contain functions and
a
dict named jinja_filters that would contain the filters like in the
config
file ? jinja_filters = dict(filter_name=filter_fct, ...) ?
The only change in tg.configuration.app_config.py
change :
# Try to load custom filters module under
app_package.lib.templatetools
try:
filter_package = self.package.__name__ +
".lib.templatetools"
autoload_lib = __import__(filter_package, {}, {},
['jinja_filters'])
autoload_filters = autoload_lib.jinja_filters.__dict__
except (ImportError, AttributeError):
autoload_filters = {}
by :
# Try to load custom filters module under
app_package.lib.templatetools
try:
filter_package = self.package.__name__ +
".lib.templatetools"
autoload_lib = __import__(filter_package, {}, {},
['jinja_filters'])
autoload_filters = autoload_lib.jinja_filters
# suppress the .__dict__
except (ImportError, AttributeError):
autoload_filters = {}
or
# Try to load custom filters module under
app_package.lib.templatetools
try:
filter_package = self.package.__name__ +
".lib.templatetools"
autoload_lib = __import__(filter_package, {}, {},
['jinja_filters'])
try:
autoload_filters = autoload_lib.jinja_filters.__dict__
except AttributeError:
autoload_filters = autoload_lib.jinja_filters
except (ImportError, AttributeError):
autoload_filters = {}
to support both...
