Flash messages are used to create notices and alerts, e.g. on form submission.
Setting form notice/alert values through Form
You can add values for flash
messages as part of form configuration, for example:
---
name: signup_form
resource: User
fields:
email:
password:
flash_notice: You have successfully signed up
flash_alert: Please fix validation errors
---
Interpolation
Values for flash
keys are processed using a Liquid parser, so they can be interpolated in the context of the current form:
---
name: signup_form
resource: User
fields:
email:
password:
first_name:
validation: { presence: true }
flash_notice: 'Thank you {{ form.first_name }}, you have successfully signed up!'
flash_alert: Please fix validation errors
---
Note
Quotes around the value of flash_notice are required if you interpolate Liquid code inside YAML
Displaying flash messages
Messages can be displayed on a page using the context variable.
{{ context.flash['notice'] }}
{{ context.flash['alert'] }}
