Hello !!
I want to create a virtual doctype.
I need some help from you guys.
Please help me.
Thanks in advance.
Hi @Kiranmai:
Check this resources:
https://frappeframework.com/docs/user/en/basics/doctypes/virtual-doctype
Hope this helps.
Thank you @avc.
But i dont know about `class VirtualDoctype(Document):
“”"This is a virtual doctype controller for demo purposes.
- It uses a single JSON file on disk as "backend".
- Key is docname and value is the document itself.
Example:
{
"doc1": {"name": "doc1", ...}
"doc2": {"name": "doc2", ...}
}
"""
DATA_FILE = "data_file.json"
@staticmethod
def get_current_data() -> dict[str, dict]:
"""Read data from disk"""
if not os.path.exists(VirtualDoctype.DATA_FILE):
return {}
with open(VirtualDoctype.DATA_FILE) as f:
return json.load(f)
@staticmethod
def update_data(data: dict[str, dict]) -> None:
"""Flush updated data to disk"""
with open(VirtualDoctype.DATA_FILE, "w+") as data_file:
json.dump(data, data_file)
def db_insert(self, *args, **kwargs):
d = self.get_valid_dict(convert_dates_to_str=True)
data = self.get_current_data()
data[d.name] = d
self.update_data(data)
def load_from_db(self):
data = self.get_current_data()
d = data.get(self.name)
super(Document, self).__init__(d)
def db_update(self, *args, **kwargs):
# For this example insert and update are same operation,
# it might be different for you.
self.db_insert(*args, **kwargs)
def delete(self):
data = self.get_current_data()
data.pop(self.name, None)
self.update_data(data)
@staticmethod
def get_list(args):
data = VirtualDoctype.get_current_data()
return [frappe._dict(doc) for name, doc in data.items()]
@staticmethod
def get_count(args):
data = VirtualDoctype.get_current_data()
return len(data)
@staticmethod
def get_stats(args):
return {}
`
