My python code is

_name = 'filedata'
_log_access = False

result = {
2: {'file_name': 'Bob', 'file_path': 'ffff',
'time_created':'2011-06-09','size':'222'}}
return result
_columns = {
'file_name' : fields.function
(compute, type='char', size=50,multi='person_data'),
'file_path' :fields.function
(compute, type='char', size=50,multi='person_data'),
'time_created':fields.function
(compute, type='char', size=50,multi='person_data'),
'size' : fields.function
(compute, type='char', size=50,multi='person_data')
}
def get_filenames(self, cr, uid, ids, context=None):
lst_dirfiles = os.listdir('/voice-recordings')
cr.execute("select id,file_name from filedata")
result = cr.fetchall()
lst_dbfiles = []
for res in result:
file_name = res[1]
if (file_name == None):
cr.execute("delete from filedata where id=%s",(res[0],))
else:
lst_dbfiles.append(file_name)
if lst_dirfiles:
for file_name in lst_dirfiles:
if file_name not in lst_dbfiles:
time_created = time.ctime(os.path.getctime
("/voice-recordings/"+file_name))
size = str(os.path.getsize
("/voice-recordings/"+file_name))+' Bytes'
file_path = "/voice-recordings/"+file_name

file_base64 = base64.b64encode(file_object.read())
file_path = "ftp://test.claudion.com:123/"+file_name
cr.execute("inserit into filedata
(file_name,file_path,time_created,size)

What you want to accomplish is not that easy. Here are some hints for your implementation:
- Use a parent object
filedatawith child objectfiledata.line filedatahas a function fieldlinesof typeone2many(relationfiledata.line)- The compute function then returns the lines which you currently want to return in function
get_filenames - Keep in mind that the function is called every time you open the view (so performance could be poor with this approach)
Here is another approach:
- Use only one model
filedata - Put the logic of
get_filenamesinto aServer Actionwhich you call by clicking onto a menu item - The server action then deletes all current records of
filedataand creates a new entry for every record withself.pool.get('filedata').create... - This approach only computes on button-click and is much faster when only displaying the data
Hope this helps.
@Andreas Brueck i checked sale/sale.py but i didnt understand anything. Can you please explain it to me
Function fields are automatically updated after a button click. If would help if you post your code in your question.
@Andreas Brueckl I added my code in question.my button calls get_filenames function which should return a view to display file names. In my code i inserted file names in to db in that function and displays it in view,. Now i dont want to save anything in db . that is my issue please help
