I have this problem when i try to generate thumbnails. If the field is
empty it inserts the photo thumb into the thumbnail. But when i try to
update that record the thumbnail doesn't change.
Here is my model:
# coding: utf8

Here is my controller:
def index():
return locals()
def parks():
if request.args(0):
parks =
db(db.park.park_state==request.args(0)).select(orderby=db.park.park_city|db.park.park_name)
else:
parks =
db(db.park).select(orderby=db.park.park_state|db.park.park_city|db.park.park_name)
return locals()
def park():
park = db.park(request.args(0)) or redirect(URL('parks'))
homes = db(db.home.pid==(request.args(0))).select(orderby=db.home.id)
return locals()
def home():
home = db.home(request.args(0)) or redirect(URL('parks'))
park = db.park(home.pid)
return locals()
def home_feed():
home = db(db.home).select(orderby=db.home.id)
return locals()
@auth.requires_membership('Admin')
def new_park():
form = crud.create(db.park, next='park/[id]')
return locals()
@auth.requires_membership('Admin')
def new_home():
db.home.pid.default = request.args(0) or redirect(URL('parks'))
db.home.price.default = "$0000.00"
db.home.posted_on.default = request.now
form = crud.create(db.home, next='home/[id]')
return locals()
@auth.requires_membership('Admin')
def edit_park():
park = db.park(request.args(0)) or redirect(URL('parks'))
form = crud.update(db.park, park, next='park/[id]')
return locals()
@auth.requires_membership('Admin')
def edit_home():
home = db.home(request.args(0)) or redirect(URL('parks'))
form = crud.update(db.home, home, next='home/[id]')
return locals()
def about_us():
return locals()
def employment_opportunities():
return locals()
def park_management():
return locals()
def make_park_thumbs():
from image import THUMBER
parks=db(db.park).select(orderby=db.park.park_state)
for park in parks:
park.update_record(photo_thumb1 = THUMBER(park.photo1, "photo_thumb1", 144,
115))
park.update_record(photo_thumb2 = THUMBER(park.photo2, "photo_thumb2", 144,
115))
park.update_record(photo_thumb3 = THUMBER(park.photo3, "photo_thumb3", 144,
115))
park.update_record(photo_thumb4 = THUMBER(park.photo4, "photo_thumb4", 144,
115))
park.update_record(photo_thumb5 = THUMBER(park.photo5, "photo_thumb5", 144,
115))
db.commit()
Here is the THUMBER function
from gluon import current
def THUMBER(image, db_photo_var, nx=120, ny=120, name='thumb'):
if image:
try:
request = current.request
from PIL import Image
import os
img = Image.open(request.folder + 'uploads/' + image)
img.db_photo_var((nx, ny), Image.ANTIALIAS)
root, ext = os.path.splitext(image)
thumb = '%s_%s%s' % (root, name, ext)
img.save(request.folder + 'uploads/' + thumb)
return thumb
except Exception:
return image
What should i do to get these working on update? At the bottom of the
controller you will notice a the make_park_thumbs() function. That was one
way of try to fix this and having it set to run on updates. However won't
generate a thumbnail it just returns the original photo. This would work if
you can tell why that function won't work. Let me know what to do.
