## How to use
### API
To get raw XML answers you should use `cbrf.api` methods:
```
>>> import cbrf
>>> cbrf.get_currencies_info()
<Element 'Valuta' at 0x10b91f688>
>>> cbrf.get_daily_rates()
<Element 'ValCurs' at 0x10b82b9a8>
>>> date_1 = datetime(2001, 3, 2)
>>> date_2 = datetime(2001, 3, 14)
>>> get_dynamic_rates(date_req1=date_1, date_req2=date_2, currency_id='R01235')
<Element 'ValCurs' at 0x1107017c8>
```
### Models
You can use base models for work with API (see examples in the tests).
`CurrenciesInfo`
```
>>> from cbrf.models import CurrenciesInfo
>>> c_info = CurrenciesInfo()
>>> c_info.get_by_id("R01305").name
'Ирландский фунт'
>>> c_info.get_by_id("R01305").eng_name
'Irish Pound'
```
`DailyCurrenciesRates`
```
>>> from cbrf.models import DailyCurrenciesRates
>>> daily = DailyCurrenciesRates()
>>> daily.date
datetime.datetime(2017, 3, 11, 0, 0)
>>> daily.get_by_id('R01035').name
'Фунт стерлингов Соединенного королевства'
>>> daily.get_by_id('R01035').value
Decimal('72.0143')
```
`DynamicCurrenciesRates`
```
>>> from cbrf.models import DynamicCurrenciesRates
>>> date_1 = datetime(2001, 3, 2)
... date_2 = datetime(2001, 3, 14)
... id_code = 'R01235'
>>> dynamic_rates = DynamicCurrenciesRates(date_1, date_2, id_code)
>>> dynamic_rates.get_by_date(datetime(2001, 3, 8)).value
Decimal('28.6200')
```
Also, you can show `DEBUG` info, by setting logger level to DEBUG in your code:
```python
import logging
logging.basicConfig(level=logging.DEBUG)
```
