Flow makes it easy to start with a new application. The Kickstarter package provides template based scaffolding for generating an initial layout of packages, controllers, models and views.


At the time of this writing these functions are only available through Flow’s command line interface. This might change in the future as a graphical interface to the kickstarter is developed.

Command Line Tool

The script flow resides in the main directory of the Flow distribution. From a shell you should be able to run the script by entering ./flow:

Flow 3.0.0 ("Development" context)
usage: ./flow <command identifier>

See './flow help' for a list of all available commands.

To get an overview of all available commands, enter ./flow help:

./flow help

* = compile time command

See './flow help <commandidentifier>' for more information about a specific command.

Depending on your Flow version you’ll see more or less the above available commands listed.

Kickstart the package

Let’s create a new package Blog inside the Vendor namespace Acme [1]:

./flow kickstart:package Acme.Blog

The kickstarter will create three files:

Created .../Acme.Blog/Classes/Controller/StandardController.php
Created .../Acme.Blog/Resources/Private/Layouts/Default.html
Created .../Acme.Blog/Resources/Private/Templates/Standard/Index.html

and the directory Packages/Application/Acme.Blog/ should now contain the skeleton of the future Blog package:

cd Packages/Application/
find Acme.Blog


Switch to your web browser and check at http://dev.tutorial.local/ if the generated controller produces some output:

A freshly created Fluid template

A freshly created Fluid template


If you get an error at this point, like a “404 Not Found” this could be caused by outdated cache entries. Because Flow should be running in Development context at this point, it is supposed to detect changes to code and resource files, but this seems to sometimes fail… Before you go crazy looking for an error on your side, try reloading the page and if that doesn’t work you can clear the cache manually by executing the ./flow flow:cache:flush --force command.

Kickstart Controllers

If you look at the drawing of our overall model you’ll notice that you need controllers for the most important domain model, being Post. For the PostController we know that we’ll need some standard actions, so let’s have them created as well:

./flow kickstart:actioncontroller --generate-actions --generate-related Acme.Blog Post

resulting in:

Created .../Acme.Blog/Classes/Domain/Model/Post.php
Created .../Acme.Blog/Tests/Unit/Domain/Model/PostTest.php
Created .../Acme.Blog/Classes/Domain/Repository/PostRepository.php
Created .../Acme.Blog/Classes/Controller/PostController.php
Omitted .../Acme.Blog/Resources/Private/Layouts/Default.html
Created .../Acme.Blog/Resources/Private/Templates/Post/Index.html
Created .../Acme.Blog/Resources/Private/Templates/Post/New.html
Created .../Acme.Blog/Resources/Private/Templates/Post/Edit.html
Created .../Acme.Blog/Resources/Private/Templates/Post/Show.html
As new models were generated, don't forget to update the database schema with the respective doctrine:* commands.


To see a full description of the kickstart commands and its options, you can display more details with ./flow help kickstart::actioncontroller.

Once complete (in the Controller chapter), this new controller will be accessible via http://dev.tutorial.local/

Please delete the file StandardController.php and its corresponding template directory as you won’t need them for our sample application [2].

Kickstart Models and Repositories

The kickstarter can also generate models and repositories, as you have seen above when using the --generate-related option while kickstarting the PostController. Of course that can also be done specifically with the kickstart:model command.

Before we do this, you should have a look at the next section on models and repositories.
