Overview

JSONloader

This module is for you if you're tired of writing boilerplate that:

  • builds a straightforward Python object from loaded JSON.
  • checks that your input-loaded-JSON has all necessary attributes for your pipeline.
  • checks that your input JSON has the right types.

Example

Main intended usage is through the JSONclass decorator, example below:

>> data['d'] = 1 # Let's fix the missing data >>> example = Example(data) # No more error in loading. >>> >>> >>> # We want to ensure we have *only* annotated parameters >>> data = {'a': 'aa', 'b': 'bb', 'c': 1} >>> @JSONclass(annotations=True, annotations_strict=True) ... class Example: ... a : str ... b : int ... >>> try: ... example = Example(data) ... except KeyError: ... print("error - extra 'c'") ... error - extra 'c' >>> del data['c'] # Let's remove unwanted data >>> example = Example(data) # No more error in loading. >>> >>> # We want to ensure we have only annotated parameters and they >>> # are of annotated type. >>> data = {'a': 'aa', 'b': 'bb'} >>> @JSONclass(annotations=True, annotations_strict=True, annotations_type=True) ... class Example: ... a : str ... b : int ... >>> try: ... example = Example(data) ... except TypeError: ... print("error - b is int") ... error - b is int">
>>> from jsonloader import JSONclass
>>> # By default we don't check for anything, we just build the object
>>> # as we received it.
>>> data = {'a': 'aa', 'b': 'bb', 'c': 1}
>>> @JSONclass
... class Example:
...     pass
...
>>> example = Example(data)
>>> example.a
'aa'
>>> example.b
'bb'
>>>
>>> # We want to ensure we have annotated parameters
>>> data = {'a': 'aa', 'b': 'bb', 'c': 1}
>>> @JSONclass(annotations=True)
... class Example:
...     a : str
...     d : int
...
>>> try:
...     example = Example(data)
... except KeyError:
...     print("error - missing 'd'")
...
error - missing 'd'
>>> data['d'] = 1  # Let's fix the missing data
>>> example = Example(data)  # No more error in loading.
>>>
>>>
>>> # We want to ensure we have *only* annotated parameters
>>> data = {'a': 'aa', 'b': 'bb', 'c': 1}
>>> @JSONclass(annotations=True, annotations_strict=True)
... class Example:
...     a : str
...     b : int
...
>>> try:
...     example = Example(data)
... except KeyError:
...     print("error - extra 'c'")
...
error - extra 'c'
>>> del data['c']  # Let's remove unwanted data
>>> example = Example(data)  # No more error in loading.
>>>
>>> # We want to ensure we have only annotated parameters and they
>>> # are of annotated type.
>>> data = {'a': 'aa', 'b': 'bb'}
>>> @JSONclass(annotations=True, annotations_strict=True, annotations_type=True)
... class Example:
...     a : str
...     b : int
...
>>> try:
...     example = Example(data)
... except TypeError:
...     print("error - b is int")
...
error - b is int
