Hello everyone, I'm really learning beancount and building my importers.
We're an international family so the multi-currency support trough fava
makes our life easier to keep track of expenses against our two base
account currencies. After doing some research I found out I can simplify
currency reporting quite a bit by adding implicit prices. One of our main
banks exposes the following fields in their export csv: amount, currency,
local amount, local currency. I;m trying to write an importer with explicit
prices (e.g. Expenses:Foo 100 GBP @@ 110 EUR) however I'm having trouble
using the data.Posting function to validate it.
from my *importers/bank_name.py*:
def implicit_amount(self, base_amount, local_amt, local_cur):
implicit_formatted = "" + local_amt + local_cur + " @@ " + amount +
self.currency # try to see if we hardcode the string...
return amount.Amount(D(base_amount), self.currency) if (base_amount,
self.currency) == (local_amt, local_cur) else implicit_formatted
[....]
amount = self.implicit_amount(row['Amount'], row['Local amount'],
row['Local currency'])
[....]
postings = [data.Posting(self.account, amount, None, None, None, None),]
*Gives..*
...r.py", line 31, in _process
if entry.postings[0].units.number > 0:
AttributeError: 'str' object has no attribute 'number'
How do I build an importer that supports implicit prices? I couldn't find
any example/existing importers that support that and where I could re-use
code from.
Thanks a lot!
