Missing Entries

[justin-meisner]

Can you explain what happens if there are 0 views on a page or when collecting a list of items for a span of a month if there are no entries for a certain day?

[PierreSelim]

I'd say it's not returning data for 0 views on a given day as for:

curl -X GET "https://wikimedia.org/api/rest_v1/metrics/pageviews/per-article/fr.wikipedia.org/all-access/all-agents/Isabelle%20Rico-Lattes/daily/20200301/20200401" -H "accept: application/json"

So you will just have a list without the 0 view days.

If you select a period on which there is never any data, you'll get a 404 error, the api client will raise a ZeroOrDataNotLoadedException (per https://github.com/Commonists/pageview-api/blob/master/pageviewapi/client.py#L150)

Ok, so the project I am working on, I am collecting data from the Citi Bank page for the month of January but nothing is appended to my list for January 3rd and January 10th only.

page_list = []
for name in names:
    page_views = pageviewapi.per_article(lang, name, start, end, access = access, agent = agent, granularity = granularity)   
    page_list.append(page_views)

print(page_list[8]['items'][0:12)

[{'project': 'en.wikipedia', 'article': 'Citi_Bank', 'granularity': 'daily', 'timestamp': '2020010100', 'access': 'all-access', 'agent': 'all-agents', 'views': 5}, 
{'project': 'en.wikipedia', 'article': 'Citi_Bank', 'granularity': 'daily', 'timestamp': '2020010200', 'access': 'all-access', 'agent': 'all-agents', 'views': 4}, 
{'project': 'en.wikipedia', 'article': 'Citi_Bank', 'granularity': 'daily', 'timestamp': '2020010400', 'access': 'all-access', 'agent': 'all-agents', 'views': 5},

{'project': 'en.wikipedia', 'article': 'Citi_Bank', 'granularity': 'daily', 'timestamp': '2020010900', 'access': 'all-access', 'agent': 'all-agents', 'views': 4}, 
{'project': 'en.wikipedia', 'article': 'Citi_Bank', 'granularity': 'daily', 'timestamp': '2020011100', 'access': 'all-access', 'agent': 'all-agents', 'views': 7}, 
{'project': 'en.wikipedia', 'article': 'Citi_Bank', 'granularity': 'daily', 'timestamp': '2020011200', 'access': 'all-access', 'agent': 'all-agents', 'views': 5}, 
{'project': 'en.wikipedia', 'article': 'Citi_Bank', 'granularity': 'daily', 'timestamp': '2020011300', 'access': 'all-access', 'agent': 'all-agents', 'views': 3}, 
{'project': 'en.wikipedia', 'article': 'Citi_Bank', 'granularity': 'daily', 'timestamp': '2020011400', 'access': 'all-access', 'agent': 'all-agents', 'views': 21}]

Why would this be happening and how can I check for it?

[justin-meisner]

Ive tried

try:
        page_views = pageviewapi.per_article(lang, name, start, end, access = access, agent = agent, granularity = granularity)   
        page_list.append(page_views)
    except (ZeroOrDataNotLoadedException):
        print("ZeroOrDataNotLoadedException")

but can't catch the exception for missing days

[PierreSelim]

You'll get the exception only if there is no days with data in your query (from my understanding of the API). Otherwise you'll have list with only the days with data.
