I have a Post.body field that is required in the model but in the UI I label this field as Details in the form.
The error rails generated is Body can't be blank.
But I really want to display that error as Please enter some Details.
How can I customize model errors in Rails 4?
The solution for a mountable engine turned out to be hidden under a giant rock...
# /config/locales/en.yml
en:
activerecord:
attributes:
'my_engine/my_model':
my_field: "Details"
errors:
models:
'my_engine/my_model':
attributes:
my_field:
blank: "can't be blank"
This should be in the documentation for mountable engines.
From the Active Record Validations guide:
[...] the :message option lets you specify the message that will be added to the errors collection when validation fails. When this option is not used, Active Record will use the respective default error message for each validation helper.
So you should be able to say:
validates :body, presence: true, message: 'Please enter some Details'
in your model.

How do you overwrite a validation message in Rails?
Even if I pass in a proc like so..
validates :my_item, uniqueness: {
scope: [:name, :type],
message: -> (object, data) do
"This item is already taken"
end,
}
It still appends the [object] to the front of the message. So that is reads: "[name of the object] This item is already taken"
Edit:
Also have tried adding a ^ to the beginning of message. Still does not work.
"^This item is already taken"
Instead of trying to override it at the model level, just leverage the fact that you're essentially trying to tweak the en locale.
In config/locales/en.yml you should be able to do something like this:
en:
activerecord:
errors:
messages:
taken: "This item is already taken."
models:
my_item:
taken: "This item is already taken."
I haven't tested this config directly, but the messages key should change the message for all models. Otherwise you can specify the message on a per-model basis. I don't believe that this will include the object name. You can find a list of the field names in the Rails Internationalization Guide.
I'm trying customize validation error messages using i18n.
Let's say I have an Address model that validates the presence of a zip_code.
My config/locales/activerecord.fr.yml looks like this
fr:
activerecord:
errors:
models:
address:
attributes:
civility:
blank: "Some message"
The issue if I fail the validation, the error message I'l have in #address.errors.full_messages will be:
"Zip code Some message"
Why does Zip code gets added to my error message ? And how can I avoid this behaviour ?
You can just add:
errors:
format: "%{message}"
This way you will just show error message with out attribute name.
Edit: this should be added to config/locales/fr.yml and not config/locales/activerecord.fr.yml (which also has errors:)
Found a gem which will solve your purpose
With the help of this gem, You just need to start the locale message with a caret and it shouldn't display the attribute name in the message.
A model defined as:
class Item < ApplicationRecord
validates :name, presence: true
end
with the following en.yml:
en:
activerecord:
errors:
models:
item:
attributes:
name:
blank: "^You can't create an item without a name."
item.errors.full_messages will display:
#You can't create an item without a name
instead of the usual
#Name You can't create an item without a name
You could simply use:
#address.errors.messages[:zip_code] # or #address.errors[:zip_code]
#=> ['Some message']
I am new to Rails. Let's say there's an Admin of a web app who can set extra fields required when a user submits a form.
For example, in a bug tracking system, Admin can set a 'checkbox' and labeled "Promised to client?". So whenever anyone enters a bug, they should be submitting this information. This can also later be changed or even removed. All depends on Admin.
So I want Admin to have following options when they create Custom Fields for a Bug entry form...
'Field name' text input
'Field type' dropdown list with values of "checkbox", "text input", "textarea" etc
'Required' a checkbox if this is required for a Bug entry
If anyone has an example on how to do this and especially how to properly validate (server side, without JS) such custom fields, it would be awesome.
If it's important, I am using MySQL.
Install nested form gem - https://github.com/ryanb/nested_form
Add Bug and CustomField models:
model Bug
has_many :custom_fields
accepts_nested_attributes_for :custom_fields, allow_destroy: true
end
model CustomField
belongs_to :bug
validates :name, presence: true
enum field_type: ["checkbox", "text input", "textarea"]
end
Read nested_form Usage to add nested fields to bug form.
I'm trying to do something very simple. I have a validates presence of in rails 3:
validates_presence_of [:first_nm]
When this fires, it gives the following crappy message:
"first nm cannot be blank"
I want to override the error message to give a friendly field name for "first nm"
"Please fill out your First Name"
I have seen all kinds of plugins, localization, humanized attributes tutorials, but these don't seem to work or are outdated. Is there no simple way to do this in Rails 3?
For localization, i've tried this:
# Sample localization file for English. Add more files in this directory for other locales.
# See http://github.com/svenfuchs/rails-i18n/tree/master/rails%2Flocale for starting points.
en:
activerecord:
errors:
messages:
taken: "has already been taken"
record_invalid: "Validation failed: %{errors}"
models:
customer:
blank: "This is a custom blank message for %{model}: %{attribute}"
attributes:
first_nm:
blank: "This is a custom blank message for first name"
Alas, no luck. My error message did not change.
On thing that might be related. I'm not inheriting from ActiveRecord, because this object is getting saved via soap, not database. Instead, I have the following:
class Customer
extend ActiveModel::Naming
include ActiveModel::Conversion
include ActiveModel::Validations
end
Have you seen this page on ActiveRecord localization? It seems to be for Rails 3. I can't test it right now, but by the document it seems you can do:
models.user.attributes.first_nm.blank = "Please fill out your First Name"
My error messages in Rails look like the following:
"Email Your email is invalid."
Why is the name of the field prefixed within the string itself? It makes the error messages look awfully odd.
Is there anyway to circumvent this behavior so that I can just see "Your email is invalid."
The documentation for generate_full_message might be of use:
The default full_message format for any locale is "{{attribute}} {{message}}". One can specify locale specific default full_message format by storing it as a translation for the key: "activerecord.errors.full_messages.format".
Additionally one can specify a validation specific error message format by storing a translation for: "activerecord.errors.full_messages.[message_key]". E.g. the full_message format for any validation that uses :blank as a message key (such as validates_presence_of) can be stored to: "activerecord.errors.full_messages.blank".
Because the message key used by a validation can be overwritten on the validates_* class macro level one can customize the full_message format for any particular validation:
# app/models/article.rb
class Article < ActiveRecord::Base
validates_presence_of :title, :message => :"title.blank"
end
# config/locales/en.yml
en:
activerecord:
errors:
full_messages:
title:
blank: This title is screwed!
In your case, since you're using the default {{attribute}} {{message}} format, you're getting "Email" for the attribute and "Your email is invalid" as the message. You could change the :message argument to "is not a valid format" and you should get "Email is not a valid format". That's the quick fix. If you want to fully customize it you can use the locale method above.
