Get corpus object by corpus name

[turicas]

Currently if I have a corpus named "test" and I want to access its object, I need some code like this:

from pypln.api import PyPLN

pypln = PyPLN('http://demo.pypln.org', ('username', 'myprecious'))
corpora = pypln.corpora()
test_corpus = [corpus for corpus in corpora if corpus.name == 'test']

We should provide better methods of retrieving corpora (better if the API provides special methods for it).
Another possible helper method is something like "get_corpus_or_create", for example:

from pypln.api import PyPLN

pypln = PyPLN('http://demo.pypln.org', ('username', 'myprecious'))
test_corpus = pypln.get_corpus_or_create('test')

We could also see other helper methods in Django's ORM to inspire us and improve library usability.

Where do we stand in regards to having access restricted only to owners of the corpora?

The code already restricts corpora by user. A user can only list and access
corpora created by himself.

Without adding a new resource to pypln.web, this problem could be solved with the code:

def get_corpus_or_create(self, corpus_name, corpus_description=''):
    '''Return the `Corpus` object related to a corpus.
    If the corpus does not exist, create it
    '''

    search_corpus = [corpus for corpus in self.corpora() if corpus.name == corpus_name]
    if not search_corpus: # corpus does not exist, need to create it
        return self.add_corpus(corpus_name, corpus_description)
    else:
        return corpus_search[0]
