Net::Jifty - interface to online Jifty applications
use Net::Jifty; my $j = Net::Jifty->new( site => 'http://mushroom.mu/', cookie_name => 'MUSHROOM_KINGDOM_SID', email => 'god@mushroom.mu', password => 'melange', ); # the story begins $j->create(Hero => name => 'Mario', job => 'Plumber'); # find the hero whose job is Plumber and change his name to Luigi # and color to green $j->update(Hero => job => 'Plumber', name => 'Luigi', color => 'Green', ); # win! $j->delete(Enemy => name => 'Bowser');
Jifty is a full-stack web framework. It provides an optional REST interface for applications. Using this module, you can interact with that REST interface to write client-side utilities.
You can use this module directly, but you'll be better off subclassing it, such as what we've done for Net::Hiveminder.
This module also provides a number of convenient methods for writing short scripts. For example, passing use_config => 1 to new will look at the config file for the username and password (or SID) of the user. If neither is available, it will prompt the user for them.
use_config => 1
new
Create a new object of type MODEL with the FIELDS set.
MODEL
FIELDS
Find some MODEL where KEY is VALUE and return it.
KEY
VALUE
Find some MODEL where KEY is VALUE and set FIELDS on it.
Find some MODEL where KEY is VALUE and delete it.
Searches for all objects of type MODEL that satisfy FIELDS. The optional OUTCOLUMN defines the output column, in case you don't want the entire records.
OUTCOLUMN
Perform any ACTION, using ARGS. This does use the REST interface.
ACTION
ARGS
Arguments are treated as arrays with (name, value) pairs so you can do the following:
$jifty->create('Model', x => 1, x => 2, x => 3 );
Some actions may require file uploads then you can use hash reference as value with content, filename and content_type fields. filename and content_type are optional. content_type by default is 'application/octeat-stream'.
Validates the given action, to check to make sure that all mandatory arguments are given and that no unknown arguments are given.
Arguments are checked CRUD and act methods if 'strict_arguments' is set to true.
You may give action as a string, which will be interpreted as the action name; or as an array reference for CRUD - the first element will be the action (create, update, or delete) and the second element will be the model name.
This will throw an error or if validation succeeds, will return 1.
Returns the action spec (which arguments it takes, and metadata about them). The first request for a particular action will ask the server for the spec. Subsequent requests will return it from the cache.
Returns the model spec (which columns it has). The first request for a particular model will ask the server for the spec. Subsequent requests will return it from the cache.
Each Net::Jifty object will do the following upon creation:
..but only if you use_config is set to true.
use_config
..unless a sid is available, in which case we're already logged in.
This method is called automatically when each Net::Jifty object is constructed (unless a session ID is passed in).
This assumes your site is using Jifty::Plugin::Authentication::Password. If that's not the case, override this in your subclass.
This will ask the user for her email and password. It may do so repeatedly until login is successful.
This uses the Jifty "web services" API to perform ACTION. This is not the REST interface, though it resembles it to some degree.
This module currently only uses this to log in.
This will post ARGS to URL. See the documentation for method about the format of URL.
URL
method
This will get the specified URL with ARGS as query parameters. See the documentation for method about the format of URL.
This will perform a METHOD (GET, POST, PUT, DELETE, etc) using the internal LWP::UserAgent object.
METHOD
URL may be a string or an array reference (which will have its parts properly escaped and joined with /). URL already has http://your.site/=/ prepended to it, and .yml appended to it, so you only need to pass something like model/YourApp.Model.Foo/name, or [qw/model YourApp.Model.Foo name].
/
http://your.site/=/
.yml
model/YourApp.Model.Foo/name
[qw/model YourApp.Model.Foo name]
This will return the data structure returned by the Jifty application, or throw an error.
This will take an array containing (name, value) argument pairs and convert those arguments into URL encoded form. I.e., (x => 1, y => 2, z => 3) becomes:
x=1&y=2&z=3
These are then ready to be appened to the URL on a GET or placed into the content of a PUT. However this method can not handle file uploads as they must be sent using 'multipart/form-date'.
See also /"form_form_data_args ARGS" and "Arguments of actions".
This will take an array containing (name, value) argument pairs and convert those arguments into HTTP::Message objects ready for adding to a 'mulitpart/form-data' HTTP::Request as parts with something like:
my $req = HTTP::Request->new( POST => $uri ); $req->header('Content-type' => 'multipart/form-data'); $req->add_part( $_ ) foreach $self->form_form_data_args( @args );
This method can handle file uploads, read more in "Arguments of actions".
Encodes FRAGMENTS and joins them with /.
FRAGMENTS
Returns STRINGS, properly URI-escaped.
STRINGS
Compares the two email addresses. Returns true if they're equal, false if they're not.
Returns true if EMAIL looks like it is the same as the current user's.
EMAIL
Retrieve user ID's email address.
ID
Loads DATE (which must be of the form YYYY-MM-DD) into a DateTime object.
DATE
YYYY-MM-DD
Retrieves the sid from the LWP::UserAgent object.
This will return a hash reference of the user's preferences. Because this method is designed for use in small standalone scripts, it has a few peculiarities.
It will warn if the permissions are too liberal on the config file, and fix them.
warn
It will prompt the user for an email and password if necessary. Given the email and password, it will attempt to log in using them. If that fails, then it will try again.
Upon successful login, it will write a new config consisting of the options already in the config plus session ID, email, and password.
This will warn about (and fix) config files being readable by group or others.
This transforms the config file into a hashref. It also does any postprocessing needed, such as transforming localhost to 127.0.0.1 (due to an obscure bug, probably in HTTP::Cookies).
The config file is a YAML document that looks like:
--- email: you@example.com password: drowssap sid: 11111111111111111111111111111111
This will write the config to disk. This is usually only done when a sid is discovered, but may happen any time.
Looks at the (given or) current directory, and all parent directories, for files named $self->filter_file. Each file is YAML. The contents of the files will be merged (such that child settings override parent settings), and the merged hash will be returned.
$self->filter_file
What this is used for is up to the application or subclasses. Net::Jifty doesn't look at this at all, but it may in the future (such as for email and password).
