I have not solve this problem, please help me~~ It is already two days~~[?]
when I upload the file, the method "add" get the parameter"image", I guess
the "image" is the data of uploaded file. I try to write the data to
disk.(follow the wiki),
I tried like this "data = image.file.read()", from wiki I know the TG should
treat it as file-object. But, It doesn't work. I get the traceback :
data = image.file.read()
AttributeError: 'dict' object has no attribute 'file'
-------------------following: detail----------------------------------
I upload the image. And I use widget "file_fields.widgets.ImageField" to
create a form_table class. like following:
--------------------------------------------------------------------
class AddFields(widgets.WidgetsList):
title = widgets.TextField(
label='Title',
validator=validators.NotEmpty(),
)
image = file_fields.widgets.ImageField(
validator=validators.NotEmpty(),
)
content = widgets.TextArea(
validator=validators.NotEmpty(),
attrs=dict(rows=10, cols=45)
)
add_form = widgets.TableForm(
fields=AddFields(),
name="w_addform",
action="/add",
submit_text="Add new!"
)
-----------------------------------------------------------
In the control.py, I create the method:
@expose()
@error_handler(index)
def add(self,title,content,image,*args, **kw):
p = model.postTable.get(int(post_id))
data = image.file.read()
newPost=model.postTable(
title = title,
content = content,
)
# open file in binary mode for writing
targetFileName = os.path.join(
os.getcwd(),
UPLOAD_DIR,
"image.filename"
)
f = open(targetFileName, 'wb')
f.write(data)
f.close()
tg.flash(
"File uploaded successfully:"%s saved as: %s" \
% (image.filename, targetFileName)
)
newUploadFile = model.uploadedFile(
filename=image.filename,
abspath=targetFileName,
size=0,
referenced_in_posts = p,
)
raise redirect("/")
---------------------------model.py-----------------------------
class postTable(SQLObject):
title = UnicodeCol(length=50)
content = UnicodeCol()
postDate = DateTimeCol(default=datetime.now())
isPublished= BoolCol(default=False)
comments=MultipleJoin('commentTable')
pictures=MultipleJoin('uploadedFile')
class uploadedFile(SQLObject):
filename = UnicodeCol(alternateID=True, length=100)
abspath = UnicodeCol()
size = IntCol()
referenced_in_posts = ForeignKey('postTable')
