QUESTION
I am trying to get a view in couchdb to include design docs. I have done it in the past, but can not get it to work today.
In a past couchapp there is a file called options.json
that contains the text:
ANSWER
Answered 2018-Apr-07 at 17:18According to this documentation, include_design
option is a boolean
.
I double-checked CouchDB to see how it saves Boolean
values by adding a document to a sample database with a Boolean
value for one of the keys:
QUESTION
I deployed a Node application to CouchDB that I developed and built from a Vue Webpack template. One of the modules I rely on, pdfjs-dist
, relies on a worker.
After running npm run build
and getting my output in dist
, I copy the output files to couchapp to deploy them to CouchDB. I get no errors during deployment and the site looks fine once it's up.
However, when I try doing something that requries pdfjs-dist, I get the error:
NetworkError: Failed to load worker script at "http://.../docuapp/documentation/_design/uploads/static/js/app.4eb1aecbadc78360a76e.worker.js" (unbekannt) Error: Loading chunk 0 failed.

So I check out the url that's failing to load, and the document is missing. But when I remove the worker
part of the url, i.e.
ANSWER
Answered 2018-Mar-06 at 08:57My guess on the problem is that pdfjs
requires the workerSrc
property to be known in runtime. But when you use webpack it will probably assign an unguessable hash on the file name, so you can't really put the filename as a string in your code.
But pdfjs
provides a solution for us! They have included a webpack file in their distribution.

QUESTION
Before installing the CouchApp utility, the Sofa blog app and the sample DB myblogdb together with CouchDB 2.1.1 my CouchDB was working find and I never seeing any Internal Server Error
.
In the last 2 hours a trojan attached itself as a process to the CouchDB. Since then I removed it, but it might have jammed some of the CouchDB's settings.
Why can't I run myblogdb
? Does this error have something to do with the breaking changes caused by upgrade to CouchDB 2.1.1
?
Firstly, couchapp push
myblogdb only works on second attempt (first attempt ends in Internal Server Error
):
ANSWER
Answered 2018-Feb-12 at 07:44It seems you are facing an issue in database creation/deletion due to a lack of cluster quorum: Issue 603 and Issue 1136.
Probably your migration from 2.0 to 2.1.1 has some effect in the membership of your node and now you have to nodes registered one for couchdb@localhost and another one for couchdb@127.0.0.1
Couchdb is considering your instalation as a two-node cluster and you are facing the lack of quorum issues.
You can check it by using this URL http://:5984/_membership
It is possible to remove the wrong node in your config by follwing these instructions.
QUESTION
I'm creating a single page CouchApp, using _attachments
to serve the JavaScript application directly from CouchDB. I've set up a vhost to db/_design/ddoc/_rewrite
to achieve this.
The data in the database can only be viewed by certain users in the _users
database, which is achieved by adding them as members to the db/_security
document.
I would like the single page application, which has PouchDB packaged, to take control of fetching data, and performing authentication by means of pouchdb-authentication. Herein lies the problem: I cannot access the application before authenticating.
That leads me to my question; Is there a way to expose the _attachments
in a design document to unauthenticated users, without granting everybody access to the rest of the database? Currently I'm weighing toward storing my app in a separate database without any members, but I would prefer to use a single database and work it out with the permission system in place.
ANSWER
Answered 2017-Oct-05 at 16:50The short answer is no. Some things you can try are:
- Create the authentication app in a separate database that's public and empty, then redirect to your app from there (you have to be in the same domain).
- Create the authentication app outside of CouchDB and use a proxy to serve everything from the same domain.
- THIS IS VERY UNSAFE AND SUBOPTIMAL but for testing purposes you can enable Basic Auth in the application, which will give you a way to authenticate via the browser before you are denied access to the database.
QUESTION
I am working in a project using CouchDB
CouchBase lite
and Android
.
I want to use a filter function so I am doing on my server end :
ANSWER
Answered 2017-Jun-27 at 01:23Filter functions aren't currently supported. See this section in the Couchbase Lite docs. (This was updated only a few weeks ago, so apologies if you saw an older version.)
You may also want to look at this GitHub issue. You can find more details on why it isn't supported. Essentially, right now, the CouchDB docs don't describe what's needed well enough to implement compatibility.

QUESTION
I am creating a CouchApp and have a question about remote databases and creating a PouchDB object.
- The CouchApp is available from htps://subdomain.website.com/
- The CouchDB instance is on htps://username.cloudant.com/database
- I use a rewrite rule in the database
- There is a Virtual Host from subdomain.website.com to username.cloudant.com/database/_design/client/_rewrite
- I am not using replication, only a direct connection
I currently create a new PouchDB object using:
var db = new PouchDB('htps://username.cloudant.com/database');
But I would rather instantiate it as:
var db = new PouchDB('/database');
or
var db = new PouchDB('database');
My guess is that PouchDB sees this as a local database instead of a remote database. Is my thinking correct, and how can I get my desired result? I want to strip the hostname of the URL because I want to keep everything portable and replicate it over other servers.

Well, that's not a matter of personal preference, you might need a remote database, a local database, or both.
Basically, as the developer you might need a remote database:

Install couchapp
You can use couchapp like any standard Python library. You will need to make sure that you have a development environment consisting of a Python distribution including header files, a compiler, pip, and git installed. Make sure that your pip, setuptools, and wheel are up to date. When using pip it is generally recommended to install packages in a virtual environment to avoid changes to the system.
