Subject [jira] [Commented] (COUCHDB-2067) Not all rows in a non-reduced view are displayed
Date Fri, 07 Mar 2014 00:18:44 GMT


ASF subversion and git services commented on COUCHDB-2067:

Commit 4e60f0b7a7b26662dde0ebc0a73c70df54e0f309 in couchdb's branch refs/heads/2041-update-ibrowse

Fauxton: Improved pagination

This is an improvement and fix on the current pagination. This fixes
pagination so that it works with all query options.

Pagination in Couchdb is quite complex
and there are plenty of situations to cater for. This new pagination
works quite differently to the previous way we had it working for a

A user can set the number of documents they want to view on a page. This
is not related to limit options in the query options - the limit option
is an overall cap of how many documents to paginate too. A limit of none
is possible and is the default. If the limit option is set to 50 and a
user wants 10 docs per page, the would then be able to paginate 3 pages
before hitting the end.

Another change is that the api url and browser url does not change when
we paginate. That happens internally and hence the new addition of
urlParams and docParams. This allows Fauxton to keep track of the
parameters that the user sees and the parameters that the document needs
to paginate.

Fixes COUCHDB-2067

> When designing a view using a map function that emits multiple items, Fauxton shows only
a subset of the rows from the view. I think, but have not confirmed, that it is only showing
as many rows as there were source documents that emitted the rows in the view.
> For example, I have THREE documents of type "A", each document having a list of "alternate
IDs," variable in length. The map function emits one or more alternate IDs per document. In
my example, I have 8 rows returned from 3 documents.
> When looking at the view, Fauxton only shows 3 rows, but it correctly reports the total
# of rows: "Showing 1-3 of 8 rows.". The "Next" button takes you to: http://localhost:5984/_utils/fauxton/#
which is putatively the list of databases, but for some reason is empty at that time (refreshing
or clicking the database link to the left correctly displays the database list).
