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 3.0.0 ("Development" context) usage: ./flow <command identifier> The following commands are currently available: PACKAGE "NEOS.FLOW": ------------------------------------------------------------------------------- * flow:cache:flush Flush all caches cache:warmup Warm up caches configuration:show Show the active configuration settings configuration:listtypes List registered configuration types configuration:validate Validate the given configuration configuration:generateschema Generate a schema for the given configuration or YAML file. * flow:core:setfilepermissions Adjust file permissions for CLI and web server access * flow:core:migrate Migrate source files as needed * flow:core:shell Run the interactive Shell database:setcharset Convert the database schema to use the given character set and collation (defaults to utf8mb4 and utf8mb4_unicode_ci). doctrine:validate Validate the class/table mappings doctrine:create Create the database schema doctrine:update Update the database schema doctrine:entitystatus Show the current status of entities and mappings doctrine:dql Run arbitrary DQL and display results doctrine:migrationstatus Show the current migration status doctrine:migrate Migrate the database schema doctrine:migrationexecute Execute a single migration doctrine:migrationversion Mark/unmark a migration as migrated doctrine:migrationgenerate Generate a new migration help Display help for a command package:create Create a new package package:delete Delete an existing package package:activate Activate an available package package:deactivate Deactivate a package package:list List available packages package:freeze Freeze a package package:unfreeze Unfreeze a package package:refreeze Refreeze a package resource:publish Publish resources resource:clean Clean up resource registry routing:list List the known routes security:importpublickey Import a public key security:importprivatekey Import a private key security:showeffectivepolicy Shows a list of all defined privilege targets and the effective permissions for the given groups. security:showunprotectedactions Lists all public controller actions not covered by the active security policy security:showmethodsforprivilegetarget Shows the methods represented by the given security privilege target server:run Run a standalone development server typeconverter:list Lists all currently active and registered type converters PACKAGE "NEOS.KICKSTARTER": ------------------------------------------------------------------------------- kickstart:package Kickstart a new package kickstart:actioncontroller Kickstart a new action controller kickstart:commandcontroller Kickstart a new command controller kickstart:model Kickstart a new domain model kickstart:repository Kickstart a new domain repository * = 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 :
./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
cd Packages/Application/ find Acme.Blog Acme.Blog Acme.Blog/Classes Acme.Blog/Classes/Controller Acme.Blog/Classes/Controller/StandardController.php Acme.Blog/composer.json Acme.Blog/Configuration Acme.Blog/Documentation Acme.Blog/Meta Acme.Blog/Resources Acme.Blog/Resources/Private Acme.Blog/Resources/Private/Layouts Acme.Blog/Resources/Private/Layouts/Default.html Acme.Blog/Resources/Private/Templates Acme.Blog/Resources/Private/Templates/Standard Acme.Blog/Resources/Private/Templates/Standard/Index.html Acme.Blog/Tests Acme.Blog/Tests/Functional Acme.Blog/Tests/Unit
Switch to your web browser and check at http://dev.tutorial.local/acme.blog if the generated controller produces some output:
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.
If you look at the drawing of our overall model you’ll notice that you need controllers
for the most important domain model, being
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
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/acme.blog/post
Please delete the file
StandardController.php and its corresponding template
directory as you won’t need them for our sample application .
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
Of course that can also be done specifically with the
Before we do this, you should have a look at the next section on models and repositories.
