Frequently Asked Questions

Maybe not so frequent, but interesting anyway. 🀷

Table of contents

Can I have my own private template?

Yes, and thanks to Copier, you can combine both in the same subproject.

Just make sure to use a separate answers file so both don't mix:

# For the 1st copy
copier --answers-file .copier-answers.private.yml copy gh:Tecnativa/private-template .
# For updates
copier --answers-file .copier-answers.private.yml update .

Check Copier docs for more details.

Can I use environments for what they're not?

You want to know if you can use devel.yaml to serve a production instance?

Wel... yes, you can, but it's not recommended nor supported.

How can I run a Posbox/IoT box service for development?

Posbox has special needs that are not useful for most projects, and is quite tightly related to specific hardware and peripherals, so it makes not much sense to ship it by default in this template.

However, for testing connection issues, developing, etc., you might want to boot a resource-limited posbox instance imitation.

The best you can do is buy a Posbox/IoT box and peripherals and use it, but for quick tests that do not involve specific hardware, you can boot it with Doodba by:

  • Add the apt dependency usbutils (which contains lsusb binary).
  • Add the pip dependencies evdev and netifaces.
  • Add a posbox container, which:
    • Can read usb devices, privileged.
    • Loads at boot all required hw_* addons, except for hw_posbox_upgrade.
    • Exposes a port that doesn't conflict with Odoo, such as 8070 i.e.

Once you apply those changes, to use it:

  1. invoke img-build --pull to install the new dependencies.
  2. invoke start to start all services.
  3. Visit http://localhost:8070 to see the posbox running.
  4. Visit http://localhost:${ODOO_MAJOR}069 to see Odoo (e.g.: $ODOO_MAJOR is 14 if deploying Odoo 14.0).
  5. Install point_of_sale in Odoo.
  6. Configure the POS in Odoo to connect to Posbox in localhost:8070.

Of course this won't be fully functional, but it will give you an overview on the posbox stuff.

Beware about possible mixed content errors.

How can I whitelist a service and allow external access to it?

This can become useful when you have isolated environments (like in devel.yaml and test.yaml by default) but you need to allow some external API access for them. I.e., you could use Google Fonts API for your customer's reports, and those reports would take forever and end up rendering badly in staging environments.

In such case, we recommend using the tecnativa/whitelist image. Read its docs there.

How do I develop for an external repo, such as OCA?

You can use the same subproject used to deploy to production.

However, you might find this pattern useful:

  1. Have your own "development-only subproject". One per Odoo version.
  2. Add the repo there to addons.yaml. For example, add server-tools: ["*"] to develop OCA's server-tools.
  3. Download code as usual.
  4. Develop.
  5. Push the PR to Github.
  6. Open your production deployment and add that PR to repos.yaml.

How to bootstrap the global inverse proxy?

This is needed for testing and production environments to be reachable.

Our supported proxy is Traefik. There must be one in each node.

To have it, use this inverseproxy.yaml file:

Traefik v1 docker compose 
version: "2.1"

services:
  proxy:
    image: traefik:1.6-alpine

  public:

Traefik v2 docker compose

TODO

Then boot it up with:

docker-compose -p inverseproxy -f inverseproxy.yaml up -d

This will intercept all requests coming from port 80 (HTTP) and redirect them to port 443 (HTTPS), it will download and install required TLS certificates from Let's Encrypt whenever you boot a new instance, add the required proxy headers to the request, and then redirect all traffic to/from odoo automatically.

It includes a security-enhaced proxy to reduce attack surface when listening to the Docker socket.

This allows you to:

  • Have multiple domains for each Odoo instance.
  • Have multiple Odoo instances in each node.
  • Add an TLS layer automatically and for free.

How to change report fonts?

Doodba ships Liberation fonts as defaults.

If you want to make another font package available, just add it to [apt.txt][dependencies] (if it's a normal Debian package) or install it in a [custom build script][build.d] called i.e. build.d/200-custom-fonts (if you need to install it in a more complex way).

If, in addition to that, you want those fonts to be the defaults, then add one (or more) of these build arguments:

  • FONT_MONO
  • FONT_SANS
  • FONT_SERIF

How to get proper assets when printing reports?

Make sure there's a ir.config_parameter called report.url with the value http://localhost:8069.

How to have good QA and test in my CI with Doodba?

Inside this image, there's the /qa folder, which provides some necessary plumbing to perform quality assurance and continous integration if you use [doodba-qa][], which is a separate (but related) project with that purpose.

Go there to get more instructions.

This project is too opinionated, but can I question any of those opinions?

Of course. There's no guarantee that we will like it, but please do it. πŸ˜‰

Where are screencasts and screenshots of my failed E2E tests?

Starting with Odoo (and Doodba) 13.0, when you're in [the devel environment][development] and run some E2E test (tours, JS tests...) that fails, Odoo will output screenshots and screencasts automatically. These are very useful for debugging.

You can find them in the ./odoo/auto/test-artifacts directory in your development host. No need to sniff around inside the container to find them.

How to get screencasts and screenshots of failed E2E tests in Odoo 12.0?

In Odoo (and Doodba) 12.0, the screencasts and screenshots feature is also supported, but it is less intuitive: just apply this patch to your devel.yaml file:

diff --git a/devel.yaml b/devel.yaml
index 2026e7c..d4e5a68 100644

You'll find Odoo logs in ./odoo/auto/test-artifacts/odoo.log file, and screencasts and screenshots will be around with some weird names. As a side effect, your container will output no logs to the console.

Since this is an awkward side effect of that setting, we're not shipping that by default.

Why pre-commit fails each time I copy or update the template?

We format here YAML files using Prettier inside pre-commit.

However, when the template is generated, you have a lot of chances that your YAML files are badly formatted. For instance, depending on the length of you alternate domains, Traefik rules might be longer or shorter, triggering a different reformat on each project, or on each update. That is expected good behavior.

Also, the way Copier formats your .copier-answers.yml file almost always violates Prettier's rules.

So, if you find out that after generating the project for the 1st time, or after updating it, it fails pre-commit validations, don't worry about that. Just let pre-commit reformat your files in next commit, and commit again.

Quick dirty recipe:

copier --force update
git add .
pre-commit run
git add .
git commit -m 'Update from template'

Why XML is broken after running pre-commit?

Doodba Copier Template enables Prettier as a pre-commit formatter for many file formats. One of these is XML, and we configure Prettier with xmlWhitespaceSensitivity: "ignore". This is like telling Prettier: "do whatever you need with XML whitespace to prettify XML files".

We do this because most times XML whitespace is meaningless, and prettifying a file without changing whitespace limits a lot what Prettier can do. However, keep in mind that in some cases, it can be meaningful.

We sometimes use XML in Odoo to generate HTML. In HTML, whitespace matters at least in these cases:

  1. Inside the <pre> element.
  2. When any element uses the CSS white-space style with certain values.

So, if you see that after running pre-commit some HTML is broken, this is possibly the cause.

Our recommendation is that, at least, before you run it for the 1st time, search <pre (literally) among your private modules, and in case you find any, be careful about what Prettier does with them.

If you install Fish, you can run these commands to find those dangerous things. If one fails with No matches for wildcard, it means there are no files to check and thus you can ignore that error:

cd $project_root/odoo/custom/src/private
fish -c 'grep "<pre" **.{xml,html}'
fish -c 'grep -E "white-space:\s*(pre|break-spaces)" **.{less,sass,scss,css}'

You can wrap any XML code among ignore tags to tell Prettier "don't touch this":

<!-- prettier-ignore-start -->
<pre>
________________
|              |
|    DOODBA    |
|    RULEZ!    |
|______________|
(\_/)  ||
(β€’γ……β€’) ||
/ γ€€ γ₯
</pre>
<!-- prettier-ignore-end -->

You can also replace our default for xmlWhitespaceSensitivity: "strict" inside your .prettierrc.yml file.

Why is Odoo saying that its database is not initialized?

This is a common problem within the development workflow. From Odoo 12.0, the database needs to be initialized by hand. You can know that you're facing this problem if you see in Odoo's logs something like this:

2020-06-09 10:24:26,715 1 ERROR ? odoo.modules.loading: Database devel not initialized, you can force it with `-i base`
2020-06-09 10:25:26,781 1 ERROR devel odoo.sql_db: bad query: SELECT latest_version FROM ir_module_module WHERE name='base'
ERROR: relation "ir_module_module" does not exist
LINE 1: SELECT latest_version FROM ir_module_module WHERE name='base...
                                   ^

You can do as the log is clearly telling you to do (side note: READ THE LOGS! πŸ˜€):

docker-compose run --rm odoo --stop-after-init -i base
invoke restart

Or you can use the resetdb task to reset your devel database:

invoke resetdb

If you use this method, Odoo will have 2 databases created. You should use the one called devel; the other one is just a cache, so the next time you run this command it's faster.

This is just a helper over these tools, which you might want to use directly instead:

Why do I get a "Connection Refused" error when trying to lauch the VSCode Firefox JS Debugger?

When using Firefox as the debugging browser, this may be happening because the path for its executable is misconfigured.

To fix this, change the firefoxExecutable variable for the VS Code Debugger for Firefox extension under Settings to your Firefox executable path. To find it, you can run:

which firefox

Then, add the following to your global settings.json file:

{
  // ...
  "firefox.executable": "/usr/bin/firefox"
  // ...
}

Why don't I see my Firefox extensions while debugging?

Firefox may load a different user profile than your personal one.

To fix that, add the following to your global settings.json file:

{
  // ...
  "firefox.profile": "default-release"
  // ...
}

Notes:

  • Your profile might be named differently. You can visit about:profiles from firefox to list them.
  • The extension is in reality using a temporary copy of that profile, so any changes you do to it won't be saved unless you configure it with "firefox.keepProfileChanges": true. If you enable that option, you may prefer using a profile named differently than your default one, so you can have 2 Firefox instances running in parallel and don't need to stop Firefox to restart it again in debug mode.

Why do I get a "Connection Refused" error when trying to lauch the VSCode Chrome JS Debugger?

When using Chrome as the debugging browser, this may be happening because the path for its executable is misconfigured.

To fix this, you must have either Chrome or Chromium installed in your system.

The Chrome executable will be selected by default and, if not installed, Chromium will be selected. Make sure you have the respective executable in your $PATH.

Why can't Firefox load the page after I start a debugging session?

It is possible that the page is not ready yet. Wait a couple of seconds and reload.

Why won't my program stop on the specified breakpoints when using Firefox?

When debugging, you must have debug=assets in your Odoo URL. By default, when you launch a debugging session, VSCode will open you browser in a new window with the correct URL. However, if you need to log in, you loose that URL. To avoid that, make sure you are not losing your cookies each time you reload a debugging session. (See Why don't I see my Firefox extensions while debugging? for how to set up your Firefox debugging profile)

When upgrading from an old template, prettier fails badly. How to update?

Whether it was prettier, npm, nodejs or whoever else, the fact is that recently there happened a prettiermageddon.

When you're updating from an older template to a newer, Copier will try to produce a vanilla project with the old template before updating it, to be able to extract a smart diff and apply the required changes to your subproject.

Since old versions of the template are broken due to this prettier problem, you cannot update anymore. Well, here's the workaround:

  1. Indicate to nodeenv that your default nodejs version is 14.14.0 by creating a file in ~/.nodeenvrc with the following contents. This will avoid the problem of prettier being unable to install:

    [nodeenv]
node = 14.14.0

  2. Update to latest template skipping prettier hook. This will avoid the problem of prettier + plugin-xml being unable to execute, even if properly installed:

    env SKIP=prettier copier update

Once all your doodba subprojects are on template v2.5.0 or later, you won't need the ~/.nodeenvrc anymore (hopefully) and you can safely delete it, as node version is pinned there and we install prettier from their new specific pre-commit repo.

When upgrading from an old template, pre-commit fails to install. What can I do?

Due to the latest updates to the pip dependency resolver, some packages fail to install.

As with the recent prettiermageddon, when you're updating from an older template to a newer, Copier will try to produce a vanilla project with the old template before updating it, to be able to extract a smart diff and apply the required changes to your subproject.

Since old versions of the template might be broken if you are running the latest pip version, you cannot update anymore. Where is what you can do to avoid it:

  1. Since pre-commit manages it's dependencies with python-virtualenv, you can indicate which version of pip it should use. There are several ways of doing it, but the easiest is with an environment variable. Just pass VIRTUALENV_PIP=20.2 before any command that fails due to this problem. For example, when running a copier update:

    env VIRTUALENV_PIP=20.2 copier update

Once all your doodba subprojects are on template v2.6.1 or later, you shouldn't have this problem, as the pre-commit hook's versions and dependencies where tailored to work with these new constraints.
