To make it works properly you have to put an icon inside. btn-floating class to make a circle button. If you need margin - simply add margin utility classes like mx-2. Without extra margins, the button edge will be flush with adjacent elements (which is sometimes the desired result). Note: Button tertiary may require additional margins. These features characterize the button tertiary. The lack of background and shadow makes the element the least visible. This means that the user should be able to easily identify which button is the most important (primary button), which is less important (secondary button) and which presents completely additional information (tertiary button).Įlements with strong, filled backgrounds and shadows attract attention the most, which is why button primary is built in this way.Ī delicate background without shadows is less engaging, so it is well suited for button secondary. $btn-white-space: nowrap to disable text wrapping for each button.īuttons, as one of the key UI elements, must have their own hierarchy. You can check out this repository to see all the described tips applied to a barebones Rails app.If you don’t want the button text to wrap, you can add the I am aware that many serious developers would frown upon seeing it in their Gemfiles, but I have a feeling this library is not going away any time soon. I’ve worked on a couple of commercial projects where using Active Admin made a lot of sense business-wise. You could even embed a dynamic React component inside Active Admin using this technique, but that’s a story for another blogpost. new ( self, nil, "Users" ) end endĬheck out this GIF to see a custom Active Admin form in action. add :base, "All emails must be valid" unless emails_valid emails_valid end def self. error e false end def valid? emails_valid =. where ( id: users_ids ) end def submit ( params ) = params return false unless valid?. It also has a submit method doing the actual work done and returning true or false based on whether action succeed.Īpp/forms/admin/users/bulk_set_email_form.rb class Admin :: Users :: BulkSetEmailForm include ActiveModel :: Conversion include ActiveModel :: Validations VALID_EMAIL_REGEX = attr_reader :users def initialize ( users_ids = ) = User. I’ve recently started following a convention where form object accepts arguments needed to render a form in an initializer. Form objects are a good way to avoid cluttering controller DSL with business logic, check out this blog post for more in depth info about them. present? || self = nil end end endĪnd then include and setup it in your model:Īpp/models/user.rb class User, url: bulk_set_email_admin_users_path do | f | % > " /> " /> įinally, you need to add a form object that contains the code required to perform the action. const_get ( "NORMALIZABLE_ATTRIBUTES" ) rescue NameError end. To avoid blank ghost attributes you need to add the following module:Ĭonfig/initializers/normalize_blank_values.rb module NormalizeBlankValues extend ActiveSupport :: Concern included do before_save :normalize_blank_values end def normalize_blank_values begin self. I can recommend this blog post for an interesting write up on potential callback use cases. It uses Active Record callbacks under the hood, but the despite all the hate they get, I think normalizing model attributes can be a valid use case for them. There is a simple way to define declarative API for keeping your attributes in a correct state. If your model does not validate a presence of data, you might end up with several attributes set to an empty string "" because that’s what is sent from an empty form field. There is a known issue with blank values populating your models after submitting a form with empty fields. Normalize blank attributesĪctive Admin uses Formtastic under the hood. With that in place, your filter queries will be persisted in session on a per page basis, making navigating the admin panel more pleasant. send ( :include, ActiveAdmin :: FiltersPersistance ) Next just add this code at the bottom of config/initializers/active_admin.rb ActiveAdmin :: BaseController.
