Re: Modify the value in a row before returning through a query

2009-08-24 Thread Merrick 

Another thread today just clued me in. Adding @property to the model
method made it work. Thank you for helping out Javier, I provided the
full example below in case someone else looks for this:

import urlparse

def stripdomain(url):
bits = urlparse.urlparse(url)
return bits[1]

class yourmodel (models.Model):
  
  domain = models.URLField(...)
  
  @property
  def strippeddomain (self):
 return stripdomain(self.domain)

Then from the shell this works:

>>> url = yourmodel.objects.get(id=1)
>>> url.strippeddomain
u'yourdomain.com'

no need for a filter, {{url.stripdomain}} will call url.stripdomain()

or, you could set url.stripdomain() as a property:

class ..:
  ...
  @property
  def stripdomain(self):
.

Re: Modify the value in a row before returning through a query

2009-08-24 Thread Merrick 

Looks like we were writing at the same time. I also was not aware you
could call a model method in a template without the parenthesis,
that's where I was getting hung up.

Again thank you.

url.stripdomain() returns:

yourdomain.com

Do you know if there is a way to have url.domain return what
stripdomain() did above? Otherwise I'll use a template filter and move
on.

Re: Modify the value in a row before returning through a query

2009-08-24 Thread Merrick 

Thank you Javier, for some reason I cannot get it working.

Using your example, I noticed the return value is stripdomain, I am
assuming that function would be outside of the model?

Assuming the code you provided, I would expect that adding the code
below, directly above the class yourmodel definition, would work:

import urlparse

def stripdomain(url):
bits = urlparse.urlparse(url)
return bits[1]

However the domain is not stripped when querying as follows:

>>> url = yourmodel.objects.get(id=1)
>>> url.domain
u'http://yourdomain.com/'

Can you tell if I am missing something?

add a function to the model, that returns the parsed field.

class yourmodel (models.Model):
  
  domain = models.URLField(...)
  
  def strippeddoamin (self):
 return stripdomain(self.domain)
