    1. The asset pipeline is a collection of components that work together. Here's a list of what they might be.Concatenation for merging together many files into one big file.Minification for compressing the contents of a file to make it smaller in size.Pre-compilation for using your language of choice to write CSS or Javascript.Fingerprinting to force reloading of asset changes (i.e., cache busing).
    1. Personally I’m not a fan of running migrations in an ENTRYPOINT script.I think it’s best suited to run this separately as part of your deploy process
    1. Performing a redirect by constructing a URL based on user input is inherently risky, and is a well-documented security vulnerability. This is essentially what you are doing when you call redirect_to params.merge(...), because params can contain arbitrary data the user has appended to the URL.

    1. Some frameworks call this “template inheritance”. In this example, we might say that the application layout “inherits from” or “extends” the base layout. In Rails, this is known as nested layouts, and it is a bit awkward to use. The standard Rails practice for nested layouts is complicated and involves these considerations
    2. But what if you want to reuse one layout within another?

    1. In this example, we still want app/models/shapes/circle.rb to define Circle, not Shapes::Circle. This may be your personal preference to keep things simple, and also avoids refactors in existing code bases. The collapsing feature of Zeitwerk allows us to do that:
    1. authenticate_by addresses the vulnerability by taking the same amount of time regardless of whether a user with a matching email is found: User.authenticate_by(email: "...", password: "...")

    1. I assume that the ActiveStorage::Attachment class gets reloaded dynamically and that the extensions are lost as they are only added during initialization. You’re correct. Use Rails.configuration.to_prepare to mix your module in after application boot and every time code is reloaded: Rails.configuration.to_prepare do ActiveStorage::Attachment.send :include, ::ActiveStorageAttachmentExtension end

    1. The reason is Rails only reads and creates the session object when it receives the request and writes it back to session store when request is complete and is about to be returned to user.
    2. Session race conditions are very common in Rails. Redis session store doesn't help either! The reason is Rails only reads and creates the session object when it receives the request and writes it back to session store when request is complete and is about to be returned to user.
    1. As you can see from the example, the session cookie is updated on every request, regardless of if the session was modified or not. Depending on when the response gets back to the client last, thats the cookie that will be used in the next call. For example, if in our previous example, if get_current_result’s response was slower than get_quiz, then our cookie would have the correct data and the next call to update_response would of work fine! So sometimes it will work and sometimes not all depending on the internet gods. This type of race condition is no fun to deal with. The implications of this is that using cookie storage for sessions when you are doing multiple ajax call is just not safe.
    2. A better solution would be to use a server side session store like active record or memcache. Doing so prevents the session data from being reliant on client side cookies. Session data no longer has to be passed between the client and the server which means no more potential race conditions when two ajax are simultaneously made!

    1. When configuring SMTP settings in an after_initialize block, the settings aren't picked up by ActionMailer. This leads to runtime errors, since ActionMailer tries the default settings.

    1. It really only takes one head scratching issue to suck up all the time it saves you over a year, and in my experience these head scratchers happen much more often than once a year. So in that sense it's not worth it, and the first time I run into an issue with it, I disable it completely.
    1. it should be normal for production apps to add authentication and authorization to their ActiveStorage controllers. Unfortunately, there are 2 possible ways to achieve it currently: Not drawing ActiveStorage routes and do everything by yourself Override/monkey patch ActiveStorage controllers None of them is ideal because in the end you can't benefit from Rails upgrades (bug fixes, etc) so the intention of this PR is to let people define a parent controller (inspired by Devise, maybe @carlosantoniodasilva can tell us his experience on this feature) so that people can add authentication and authorization in a single place and still benefit from the default controllers.

    1. The combined stuff is available to components using the page store as $page.stuff, providing a mechanism for pages to pass data 'upward' to layouts.

      bidirectional data flow ?! That's a game changer.

    1. As of Rails 7.0+, Active Record has an option for handling associations that would perform a join across multiple databases.

      impressive

    1. You can also use silence_redefinition_of_method if you need to define the replacement method yourself (because you're using delegate, for example).
    1. acts_as_tokened Quickly adds rails 5 has_secure_token to your model, along with some Post.find() enhancements to work with tokens instead of IDs.
    2. include Effective::CrudController
    3. # All queries and objects will be built with this scope resource_scope -> { current_user.posts } # Similar to above, with block syntax resource_scope do Post.active.where(user: current_user) end

    1. 1) Order the one for your particular vehicle if you can otherwise the curvature of the side rails may not be correct which will dent the metal once secured.2) Look/feel under the headliner if you can prior to drilling into the roof, you may hit a beam which will be troublesome running a screw through multiple pieces of metal. You can also cut the side rails if necessary.3) Use non-corrosive silicone (does not smell like vinegar which will eventually eat away at the paint and rust) to seal up the holes that you drill into the roof. End caps doesn't appear to make a tight seal.4) Screws are stainless which are typically soft. Be careful not to overnighten! I actually used a rivnut/blind nut tool instead of just screws (About 25 bucks here on Amazon).

    1. Rails' inability to automatically route my link_to and form_for in STI subclasses to the superclass is a constant source of frustration to me. +1 for fixing this bug.

      I've had to work around this by doing record.as(BaseClass)

    1. As you can see Rails already adds error messages from associated models and doing it wrongly: Merging together errors from different models under same has_many association. :"employments.company"=>["can't be blank"] And this is wrong.

    1. class AuthConstraint def initialize(&block) @block = block || ->(_) { true } end def matches?(req) user = current_user(req) user.present? && @block.call(user) end def current_user(req) User.find_by_id(session[:user_id]) end end This is a flexible approach to defining route access based on any desired variable (roles, auth, etc...)

      Good solution, and might be needed if you want to base routes on roles, etc. — but this one is even easier if all you need is for it to be conditional based on signed in or not (because devise provides authenticated helper):

    1. Meh... as I said earlier, I think using Webpack is the recommended way now. Another issue is there is no way to generate source maps in production.
    2. But last I have seen comments from DHH, he considered webpack(er) recommended for JS, but Sprockets still the preferred solution for (S)CSS.
    3. I agree about lack of maintenance. It's probably because people use more and more Webpack.
    1. Run the complete unit with a certain input set, and test the side-effects. This differs to the Rails Way™ testing style, where smaller units of code, such as a specific validation or a callback, are tested in complete isolation. While that might look tempting and clean, it will create a test environment that is not identical to what happens in production.
    1. Responders don't use valid? to check for errors in models to figure out if the request was successful or not, and relies on your controllers to call save or create to trigger the validations.

    1. While Trailblazer offers you abstraction layers for all aspects of Ruby On Rails, it does not missionize you. Wherever you want, you may fall back to the "Rails Way" with fat models, monolithic controllers, global helpers, etc. This is not a bad thing, but allows you to step-wise introduce Trailblazer's encapsulation in your app without having to rewrite it.
    1. By default, hashes remove any keys that aren't given as nested filters. To allow all hash keys, set strip: false. In general we don't recommend doing this, but it's sometimes necessary.
    2. ActiveInteraction type checks your inputs. Often you'll want more than that. For instance, you may want an input to be a string with at least one non-whitespace character. Instead of writing your own validation for that, you can use validations from ActiveModel. These validations aren't provided by ActiveInteraction. They're from ActiveModel. You can also use any custom validations you wrote yourself in your interactions.
    3. Since we're using an interaction, we don't need strong parameters. The interaction will ignore any inputs that weren't defined by filters. So you can forget about params.require and params.permit because interactions handle that for you.
    4. Note that it's perfectly fine to add errors during execution. Not all errors have to come from type checking or validation.
    1. with ActiveForm-Rails, validations is the responsability of the form and not of the models. There is no need to synchronize errors from the form to the models and vice versa.

      But if you intend to save to a model after the form validates, then you can't escape the models' validations:

      either you check that the models pass their own validations ahead of time (like I want to do, and I think @mattheworiordan was wanting to do), or you have to accept that one of the following outcomes is possible/inevitable if the models' own validations fail:

      1. if you use object.save then it may silently fail to save
      2. if you use object.save then it will fail to save and raise an error

      Are either of those outcomes acceptable to you? To me, they seem not to be. Hence we must also check for / handle the models' validations. Hence we need a way to aggregate errors from both the form object (context-specific validations) and from the models (unconditional/invariant validations that should always be checked by the model), and present them to the user.

      What do you guys find to be the best way to accomplish that?

      I am interested to know what best practices you use / still use today after all these years. I keep finding myself running into this same problem/need, which is how I ended up looking for what the current options are for form objects today...

    2. I agre with your concern. I realy prefer to do this : form.assign_attributes(hash) if form.valid? my_service.update(form) #render something else #render somthing else end It looks more like a normal controller.
    3. My only concern with this approach is that if someone calls #valid? on the form object afterwards, it would under the hood currently delete the existing errors on the form object and revalidate. The could have unexpected side effects where the errors added by the models passed in or the service called will be lost.
    4. My concern with this approach is still that it's somewhat brittle with the current implementation of valid? because whilst valid? appears to be a predicate and should have no side effects, this is not the case and could remove the errors applied by one of the steps above.
    1. By explicitly defining the form layout using ::property there is no more need for protecting from unwanted input. strong_parameter or attr_accessible become obsolete. Reform will simply ignore undefined incoming parameters.
