Liquid Variables Not Rendering in Custom Email Notifications Templates

Liquid Variables Not Rendering in Custom Email Notifications Templates

Problem:

When customizing email templates via the email_templates table (as per documentation), Liquid variables (e.g., {{ resource.name }}, {{ token }}) are not rendered. The emails send, but variables are missing. Default templates work correctly.

Troubleshooting:

• FRONTEND_URL is correct.
• account_id and locale are set in email_templates.
• Tried various template_type values (0-5).
• Simplified template to just {{ resource.name }} - still doesn't work.
• Default email templates do render variables correctly.

Environment:

• Chatwoot: v4.0.3
• Docker Compose, PostgreSQL
• Ubuntu 22.04

Question:

Has anyone successfully customized email templates with Liquid variables using the email_templates table? Is there a specific configuration or template_type value required? Am I missing something in how variables are passed to these templates? Any guidance would be appreciated!

The .erb templates located on app/views/devise/mailer, which are:

• confirmation_instructions.html.erb
• password_change.html.erb
• reset_password_instructions.html.erb
• unlock_instructions.html.erb
  Can be edited directly. But the idea is that this templates could be edited via the email_templates table on the chatwoot postgress database, so that we can take advantage of sending this templates on multiple languages.

Right now we are able to replace this default templates on the email_templates table, but the variables are not being rendered as I mentioned on the initial post.

@ldaniel.jmz this is not a priority, but we will try to take a look as bandwidth permits, the ideas is to convert everything into liquid. but this would take some engineering effort to move them to a custom mailer and decouple the variables.

Nice, good to know! We can take advantage of multilanguage support for templates if they're unified on liquid format! 🙌

Update on Email Template Customization

For those wondering about the current state of email template customization, here's a recap:

• Liquid Templates:
  • You can customize templates located in app/views/mailers/ that end with .liquid using the Chatwoot guide.
  • This method allows for multilanguage templates via the locale column in Chatwoot's email_templates PostgreSQL table.
• ERB Templates:
  • Templates located in app/views/mailers/ ending with .erb and those in app/views/devise/mailer/ must be manually replaced or edited.
  • Ensure you maintain the ERB coding syntax.

Current Limitations and Future Considerations:

• Ideally, all email templates would be customizable via the Chatwoot guide for multilanguage support.
• Currently, this is not possible due to the presence of ERB templates.

Statement from @sojan-official:

• @sojan-official has stated that converting all templates to Liquid is not a current priority.
• He agrees that all templates should be converted to liquid.
• The team will work on it in the future.
