Hi,
its driving me nuts. I used the code from web2pyslices to generate
thumbnails:
db.py:
db.define_table('Images',
Field('Name',length=512),
Field('Image','upload'),
Field('thumb','upload',writable=False,readable=False),
format = '%(Name)s' # <<< important
)
db.define_table('Article',
Field('Title',length=512),
Field('Content','text'),
Field('Submitted','datetime',default=datetime.datetime.now()),
Field('Views','integer',default=0),
Field('TopImage',db.Images)
)
default.py:
def download():
return response.download(request, db)
def makeThumbnail(dbtable,ImageID,size=(200,200)):
try:
thisImage=db(dbtable.id==ImageID).select()[0]
import os, uuid
except:
print "Error while loading libraries"
return
try:
from PIL import Image
except:
print "Error while Importing PIL library"
return
print request.folder + 'uploads/' + thisImage.Image
im=Image.open(request.folder + 'uploads/' + thisImage.Image)
im.thumbnail(size,Image.ANTIALIAS)
thumbName='uploads.thumb.%s.jpg' % (uuid.uuid4())
im.save(request.folder + 'uploads/' + thumbName,'jpeg')
thisImage.update_record(thumb=thumbName)
response.flash = 'Thumb created everything went fine'
return
def newImage():
dbtable = db.Images #uploads table name
if len(request.args):
records = db(dbtable.id==request.args[0]).select()
if len(request.args) and len(records):
form = SQLFORM(dbtable, records[0], deletable=True)
else:
form = SQLFORM(dbtable)
if form.accepts(request.vars, session):
response.flash = 'Entry for Images Database accepted,start creating
thumb'
makeThumbnail(dbtable,form.vars.id,(200,200))
elif form.errors:
response.flash = 'Error in Form for Images Database'
## Quick list just to demonstrate...
list = crud.select(dbtable)
return dict(form=form,list=list)
def Article():
id=request.vars.id
row=db(db.Article.id==id).select()
row[0].update_record(Views=row[0].Views+1)
if len(row)==0:
redirect(URL(r=request,f='Articles'))
return dict(Article=row[0])
article.html
{{extend 'layout.html'}}
<h1> {{=Article.Title}} </h1>
<br>
<center>
{{print URL(r=request, c='default',
f='download',args=Article.TopImage.thumb)}}
{{=IMG(_src=URL(r=request, c='default',
f='download',args=Article.TopImage.thumb),_style="display:block;")}}
</center>
<br>
{{=XML(Article.Content)}}<br><br>
the thumbnail is generated by the code as it should. and it lands in the
upload folder with the original image as it should. if I change the
article.TopImage.thumb to .image it works perfectly. if I change it to
.thumb again no image is displayed. the path and name I get from the print
seem to be correct at least it is the same path as for the origianl image.
thanks for your help guys
