Best way to set up Fjord on your computer is by using Vagrant to set Fjord up in a virtual machine.
This definitely works for Mac OSX and Linux and probably works for Windows, too. If you have issues, please let us know.
If you have a GitHub account, you should fork the Fjord repository and then clone your fork:
git clone https://github.com/<USERNAME>/fjord.git
If you do not have a GitHub account, that’s ok! Clone the official Fjord repository this way:
git clone https://github.com/mozilla/fjord.git
This creates a directory called fjord/. We’ll call that the “Fjord repository top-level directory”.
It’s likely there will be a version mismatch between the version of Virtualbox you’re using and the version of the Virtualbox Guest Additions in the image you’re going to use.
If you’re using Mac OSX or Linux, you can do this from the Fjord repository top-level directory:
If you’re not using Mac OSX or Linux or that doesn’t work, then you can do it by hand:
# Installs the VirtualBox Guest plugin vagrant plugin install vagrant-vbguest # Creates and launches the vm without provisioning it vagrant up --no-provision # Runs a command in the vm to remove the packages in the vm that # are the cause of the mismatch vagrant ssh -c 'sudo apt-get -y -q purge virtualbox-guest-dkms virtualbox-guest-utils virtualbox-guest-x11' # Halts the vm so you can move onwards vagrant halt
After that, the versions of the two things should be the same and you should be good to go to the next step.
This will build a VirtualBox vm using Vagrant. The vm will have Ubuntu Linux 14.04 installed in it. Fjord works in this environment.
Run this commands in the Fjord repository top-level directory:
It takes a while the first time you do this since it has to create the virtual machine and provision it. First it downloads an Ubuntu Linux 14.04 image (~300mb), then it installs some software in this image like MySQL and Elasticsearch. Then it sets things up so that Fjord runs in this VM using the files on your machine. This allows you to use whatever editor you like on your machine to edit code that runs in the VM without having to copy files around.
After you’ve created a vm, we have some minor setup to do:
# Create a shell on the guest virtual machine vagrant ssh # Change into the fjord/ directory cd ~/fjord
First we download all the product detail data:
# Update product details ./manage.py update_product_details -f
Then we set up the database:
# Create the database and a superuser ./manage.py syncdb # Run the db migrations ./manage.py migrate
It will ask if you want to create a superuser. You totally do! Create a superuser that you’ll use to log into Fjord.
The username and password don’t matter, but the email address does. You must choose an email address that is your Persona identity. If you don’t have a Persona identity, you can create one at the Persona site.
You can create a superuser at any time by doing:
After that, let’s generate some data in the database so that we have something to look at. We’ll then need to index that data so it shows up in searches.
# Generate sample data ./manage.py generatedata # Index the sample data into Elasticsearch ./manage.py esreindex
Fjord is a Django project. We use the Django runserver to run the website to test it.
First, if you haven’t got a running virtual machine, launch it with:
Then, ssh into the virtual machine:
This gives you a shell in the virtual machine that lets you run all the Django commands, run the test suite, etc.
To launch the Django runserver, use the vagrant ssh shell and do:
cd ~/fjord ./manage.py runserver 0.0.0.0:8000
Then on your host computer, use your browser and go to http://127.0.0.1:8000. You should see Fjord.
Sample data is tied to a specific moment in time. You’ll need to run the generatedata command every time you need fresh data.
The generatedata command only generates data and saves it to the db. After running generatedata, you’ll need to add that data to the Elasticsearch index:
./manage.py generatedata ./manage.py esreindex
You can call generadata as many times as you like.
|Command to run on host||Explanation|
|vagrant up||Launches the vm|
|vagrant ssh||SSHs to the vm|
|vagrant halt||Halts the vm|
|vagrant status||Status of the vm|
|vagrant destroy||Destroys the vm (not recoverable!)|
See more in the Vagrant documentation. If you have questions, let us know.
You can see the complete list of ./manage.py commands by typing:
For each command, you can get help by typing:
./manage.py <COMMAND> --help
We use the following ones pretty often:
|generatedata||Generates fake data so Fjord works|
|runserver||Runs the Django server|
|test||Runs the unit tests|
|migrate||Migrates the db with all the migrations specified in the repository|
|shell||Opens a Python REPL in the Django context for debugging|
|esreindex||Reindexes all the db data into Elasticsearch|
|esstatus||Shows the status of things in Elasticsearch|
|update_product_details||Updates the product details with the latest information|
You can get sample data in your db by running:
This will generate 5 happy things and 5 sad things so that your Fjord instance has something to look at.
If you want to generate a lot of random sample data, then do:
./manage.py generatedata --with=samplesize=1000
That’ll generate 1000 random responses. You can re-run that and also pass it different amounts. It’ll generate random sample data starting at now and working backwards.
Vagrant sets up a forward between your host machine and the guest machine. You need to run the runserver in a way that binds to all the ip addresses.
Run it like this:
./manage.py runserver 0.0.0.0:8000
The test suite will create and use this database, to keep any data in your development database safe from tests.
Run the test suite this way:
./manage.py test -s --noinput --logging-clear-handlers
For more information, see the test documentation.
Over time, code changes to Fjord require changes to the database. We create migrations that change the database from one version to the next. Whenever there are new migrations, you’ll need to apply them to your database so that your database version is the version appropriate for the codebase.
To apply database migrations, do this:
For more information on the database and migrations, see Maintaining the db.
This allows you to open up a Python REPL in the context of the Django project. Do this:
Fjord uses Elasticsearch to index all the feedback responses in a form that’s focused on search. The front page dashboard and other parts of the site look at the data in Elasticsearch to do what they do. Thus if you have no data in Elasticsearch, those parts of the site won’t work.
To reindex all the data into Elasticsearch, do:
If you want to see the status of Elasticsearch configuration, indexes, doctypes, etc, do:
Event data like Firefox releases and locale data are all located on a server far far away. Fjord keeps a copy of the product details local because it requires this to run.
Periodically you want to update your local copy of the data. You can do that by running:

Maintaining the db covers database-related things like updating your database with new migrations, creating migrations, etc.
Maintaining ElasticSearch covers Elasticsearch-related things like maintaining your Elasticsearch index, reindexing, getting status, deleting the index and debugging tools.
Maintaining l10n covers how we do localization in Fjord like links to the svn repository where .po files are stored, Verbatim links, getting localized strings, updating strings in Verbatim with new strings, testing strings with Dennis, linting strings, creating new locales, etc.
Maintaining Vendor Library covers maintaining vendor/ and the Python library dependencies in there.
