Role models are important. -- Officer Alex J. Murphy / RoboCop. RuboCop is a Ruby static code analyzer (a.k.a. linter) and code formatter. Out of the box it will enforce many of the guidelines outlined in the community Ruby Style Guide. Apart from reporting the problems discovered in your code, RuboCop can also automatically fix many of them for you. RuboCop is extremely flexible and most aspects of its behavior can be tweaked via various configuration options. Working on RuboCop is often fun, but it also requires a great deal of time and energy.

I'm aware of the recent mimemagic issues, which I managed to resolve on one of my Rails projects by bundle updating to 0.3.7 - but for some reason, I can't resolve it on the project below.
I have a Rails 6 project which I'm setting up for the first time on a new laptop. My laptop doesn't have the correct Ruby setup, so I've added a Dockerfile to my project like so:-

Style questions aside, if you want to maintain your current semantics, you can break lines at certain keywords and operators without escaping newlines with backslashes. For example:
Im running ruby version 2.6.1 with docker. Rake gem is version 13.0.1.
Whenever I tried docker-compose up, it always fails and throws this error everytime:
This error did not exist before.

I'm not really sure what happened and why but I tried doing this on my rails container and I was no longer receiving the said error.

I will like to disable a cop for a specific block or method.
I know it is possible to disable a cop for the whole project using .rubocop.yml but I just want to deactivate the cop temporarily for a specific portion of the code...

I answer my question because it is always very difficult for me to find the reference to this solution:
The project I'm working on requires some of the data table's column titles to be referenced/defined in a footnote below the table.
As it's dynamic content that will be looped over depending on how many of the column titles require footnotes, I need to handle most of this in via models/helpers. I have been able to replicate the html our US designer wants using
content_tag, but rubocop is whining about the use of content tag and says I should be using
tag instead. But I can't get the nesting of the html tags to work at all using the
The section html I'm trying to produce is this (which will be repeated for as many footnotes are needed):...

It looks to me like
tag are part of rails 22.214.171.124. It looks like only what is being deprecated is the format of the
tag helper defaulting to an XHMTL empty tag instead of an HTML 5 type of tag. There are reports of incorrect behavior by rubocop targeting
content_tag when it is
tag which should be targeted.
You might check on the arguments to
content_tag for empty tags since it might not be defaulting the same way as before.
Im defining a class within the routes block to handle ajax stuff...
ANSWERAnswered 2021-Apr-18 at 23:55
From the docs:
Do not define constants within a block, since the block’s scope does not isolate or namespace the constant in any way.
If you are trying to define that constant once, define it outside of the block instead, or use a variable or method if defining the constant in the outer scope would be problematic.
You can define the
OnlyAjaxRequest class outside the block to fix the issue.
I use pundit for authorization and RSpec for testing in my rails app. Due to this, I had to create specs for the policies.
However, I am having a problem with rubocop throwing an error: RSpec/MultipleMemoizedHelpers.
I understand that this means I have too many
subject calls. My issue is I'm not quite sure how to resolve or refactor my code so it adheres to the proper number of calls I should make.
Another thing, is it okay to disable RSpec/MultipleMemoizedHelpers for spec files?
Here are three of the policy spec files that are an issue....
ANSWERAnswered 2021-Apr-18 at 13:36
RSpec/MultipleMemoizedHelpers cop is controversial. It wants you to limit the number of
let to an arbitrary number.
I fought hard against it. To me it is similar to a cop that would raise an offense because you have too many variables.
rubocop-ast have it disabled, while we typically enable more cops that the default. Note that you could change these
def and the offenses go away (although you haven't changed anything;
let is just syntax sugar for a
Sharing your factories seems like a good idea, and I recommend disabling the cop too.
I can't find any solution on how to disable some Rubocop inspections in RubyMine. Ex. the "use single quote string instead of double-quote".
And there are some other inspections that I would like to disable.
I tried going to the "Editor | Inspections" in the settings but you can't change it there.
I also saw that there should be a
.rubocop.yml file somewhere but I can't find it anywhere.
It would be also cool if I could set it for every project rather than just this one....

I have a multi-stage Dockerfile for building a Rails app that includes webpacked frontend assets.
The step with
RUN bin/rails assets:precompile calls webpack to build all the .js and .css assets to publish to
public/packs. This works fine. The problem is, the changes from this
RUN step are not persisted. One would expect the following to work:
ANSWERAnswered 2021-Mar-23 at 11:32
The only particularly obvious effect of a
VOLUME directive is that it prevents any following
RUN command from changing that directory. Declaring a
VOLUME in your Dockerfile is almost never necessary (and volumes aren't appropriate storage for source code); you can just delete that line and nothing bad will happen.
For full transparency, I started learning about Cucumber an hour ago. I've been following a concise tutorial on using Selenium in Ruby with Cucumber and I've had no issues until this point.
In essence, I'm trying to run a test scenario(?) but I am receiving this error:...
ANSWERAnswered 2021-Mar-18 at 15:18
This is a RubyMine bug. Nothing we can fix on the Cucumber end.
You can either consult a non-recommended monkeypatch / hack. Or downgrade to an early version of Cucumber5.
See https://youtrack.jetbrains.com/issue/RUBY-27294 for more information, including other possible workarounds and a time-frame for the fix from Jetbrains.
