Goodmorning people,
I'm teaching myself web2py and I've a little question for understanding how
can i do ...
I've a form (becomes from a table) with an upload field
i would to upload an html file and I would to parse it in the mean time ..
or just after the completition of the operation...
eg.: after i've clicked on the submit button so i would import the file and
after the parsing filling a new table with the results of the html parse
operation.
my table :
db.define_table("files",
Field("name", unique=True),
Field('country', requires=IS_IN_DB(db,
'country.printable_name')),
Field("files", "upload", custom_store=store_file,
custom_retrieve=retrieve_file)
)
I used (thanks to web2py group experts) these two function for storing and
renaming the file uploaded :
def store_file(file, filename=None, path=None):
path = "applications/myappuploads"
if not os.path.exists(path):
os.makedirs(path)
pathfilename = os.path.join(path, filename)
dest_file = open(pathfilename, 'wb')
try:
shutil.copyfileobj(file, dest_file)
finally:
dest_file.close()
return filename
def retrieve_file(filename, path=None):
path = "applications/myapp/uploads"
return (filename, open(os.path.join(path, filename), 'rb'))
after I've connected in my display_form() all the things ...
def display_form():
if len(request.args):
form=SQLFORM(db.files, request.args[0], upload=URL("download"))
else:
form=SQLFORM(db.files, upload=URL("download"))
txt_content=[]
if form.process(onvalidation=validate).accepted:
content=StringIO.StringIO(data)
msg = process_file(content)
response.flash = T(msg)
elif form.errors:
response.flash = T('some errors occurred')
else:
pass
return {"form":form}
I validate the uploaded file giving the name that i've put in the field
"name"
def validate(form):
if form.vars.files is not None:
form.vars.files.filename = form.vars.name + ".html"
and my process_file is :
def process_file(content):
all_lines = content
msg = 'content not processed'
for line in all_lines:
try:
msg = 'processed succesfully'
except:
msg = 'error processing'
return msg
here i've my problems .... in which way I can parse the html file, with
which html parser ?
Thank you in advance
Luca
