6.5. Has¶
6.5.1. Has¶
-
class
easydata.parsers.has.Has(*args, contains: Optional[Union[list, str]] = None, ccontains: Optional[Union[list, str]] = None, contains_query: Optional[easydata.queries.base.QuerySearchBase] = None, has_value: bool = False, empty_as_false: bool = True, **kwargs)[source]¶ Bases:
easydata.parsers.text.Text
Getting Started¶
Has supports any query object for fetching data.
>>> ed.Has(ed.jp('info.stock')).parse({'info': {'stock': True}})
True
In this case if jp returns None, then bool parser will also return False.
>>> ed.Has(ed.jp('invalid-key')).parse({})
False
Use of query selectors is not required, as we can see bellow.
>>> ed.Bool().parse(True)
True
Parameters¶
-
contains¶
contains property can accept list of keys which will be used for a
match in a lookup text. If match is found then True is returned. Please
note that search keys are not case sensitive and regex pattern as a key is
also accepted.
>>> ed.Has(contains=['pro 13']).parse('Easybook Pro 13')
True
-
ccontains¶
ccontains works in a same way as contains parameter, with an exception
that keys are case sensitive.
>>> ed.Has(contains=['Pro 13']).parse('Easybook Pro 13')
True
Lets try with lowercase keys.
>>> ed.Has(contains=['Pro 13']).parse('Easybook Pro 13')
False
-
contains_query¶
contains_query is a powerful feature that enables you to specify dynamic
search keys by using query selectors. In example bellow we will use jp
query selector to get our contains keys.
>>> test_dict = {'title': 'Easybook Pro 13', 'info': {'brand': 'Easybook}'}}
>>> ed.Has(ed.jp('title'), contains_query=ed.jp('info.brand')).parse(test_dict)
True
