## Using couchapp with multiple design documents

# Here is what I did to use couchapp with multiple design documents
# This is mostly using the command line.

## GOAL ##
#  I want to setup a project for a new database test6 with a design doc called
# design_doc1

# Make sure couchdb and couchapp are installed and that couchdb is started.

# First check that test6 doesn't exist

%  curl http://127.0.0.1:5984/test6   

{"error":"not_found","reason":"no_db_file"}

# OK. That was expected.

# Generate a new couchapp.

% couchapp generate test6


# On my machine (Debian squeeze), couchapp seems to generate the directory with owner root. Change owner to john
%chown -R john ./test6

% cd test6 

% ls                            
_attachments   evently  language  shows    vendor
couchapp.json  _id      lists     updates  views


% vi .couchapprc

# Now edit .couchapprc as follows so it looks like

{ "env": 
  { "default": 
    {  "db":"http://127.0.0.1:5984/test6" }
  } 
}

% cat  .couchapprc

{ "env": 
  { "default": 
    {  "db":"http://127.0.0.1:5984/test6" }
  } 
}

# NOTE: It looks like couchapp doesn't pick up the default db in what follows when I
# do couchapp push

# Make a directory for design documents:

% mkdir _design

# Make a directory for design_doc1

%mkdir _design/design_doc1

# move the design doc files created with couchapp generate to the design_doc1 directory:

% mv _attachments evently lists shows updates vendor views ./_design/design_doc1

# review the directory structure

%ls  _design/design_doc1
                                 
_attachments  evently  lists  shows  updates  vendor  views

# now push design_doc1. Note that I have to include the url of the database as a parameter.
# couchapp doesn't seem to pick up the default db when I push from the _design directory.
#  http://127.0.0.1:5984/test6     is the url of the new db

% couchapp push _design/design_doc1 http://127.0.0.1:5984/test6

# Now check to see if db test6 was created:

% curl http://127.0.0.1:5984/test6                                
{"db_name":"test6","doc_count":1,"doc_del_count":0,"update_seq":1,"purge_seq":0,"compact_running":false,"disk_size":106585,"instance_start_time":"1282603665650439","disk_format_version":5}

# Now go into a browser and take a look at the test6 db

# http://127.0.0.1:5984/_utils/database.html?test6

# You should see

#  "_design/design_doc1" listed on the html page. That's good, that means that design_doc1 was created.

# Take a look at design_doc1 in the futon web admin:

# Open this URL in your browser:  
# http://127.0.0.1:5984/_utils/document.html?test6/_design/design_doc1
# You should see a nice listing of the design_doc1

# Try opening the index page in your browser:

# http://127.0.0.1:5984/_utils/document.html?test6/_design/design_doc1/index.html

# This should serve up index.html from the _attachments subdirectory   test6/_design/design_doc1/_attachments/index.html

# Couchapp generate had created a sample view called recent-items. Try querying it:

% curl http://127.0.0.1:5984/test6/_design/design_doc1/_view/recent-items

{"total_rows":0,"offset":0,"rows":[]}

# That's it. Multiple design can be used to create different  interfaces for users with different roles. For example, consider
# some data and the different ways that and admin versus a regular user interacting with it.

# That's it!!!
