inflector | Doctrine Inflector is a small library | Web Framework library

Your namespace is wrong, there is no Bake folder in the path to your class file. This mismatch will cause checks for the class' existence to fail, and subsequently cause the autoloader to load the file multiple times, resulting in the error that you're seeing, as a class can only be declared once.

As mentioned in the comments, the problem with your code is that it uses non US English names, which violates CakePHP's naming conventions, and breaks the magic around that which is using inflection for tasks like finding and loading the default model for a controller based on singularizing the controller name.

Inflection mostly works on word endings as known from US English based words, it's not like the inflector knows about all possible words, it's just some basic grammar rules and a few exceptions, so things might work for words from other languages simply because their ending happens to match a rule. -ois as in your Emplois name matches the rule for uninflected words, it will catch words like bourgeois or Illinois. Regarding your example from the comments, Projets and Projects, there's no difference for the inflector, it will not match anything irregular, but just the the -s ending rule, and therefore being interpreted as plural, so it happens to just work by chance, so to speak.

Ideally you use proper English names everywhere. If you cannot work that out right now, then the next best thing would be to either use custom inflections, or depending on the situation where inflection is failing, interfer manually, like using loadModel() manually. An example for custom inflection for Emploi/Emplois would be:

It was an Intelli-J issue!

So, cleaning the Intelli-J dependency spaghetti up solved it!

1. File > Invalidate cache ... and restart. Helped a bit.
2. Closing the Intelli-J project. Then removed manually the ".idea" folder and any *.iml file.

Yes, I did option 1 previously. Especially doing action 2 solved it within a minute.

Add this option:

The answer was to edit connectors_data.rb to be:

The problem is that the doctrine inflector method, maybe you need upgrade it otherwise other solution is upgrade your version of Laravel to at least 7.x.

Try to upgrade your version of your packages in your command line:

Think you may need to run the generator so that it can create the devise initializer file. /config/initializers/devise.rb

Rails additions to base Ruby classes, like String#parameterize, are part of the Active Support Core Extensions. The activesupport gem can be installed and used independent of Rails.

To keep the default footprint low, ActiveSupport allows you to require only the individual extensions you want to use. In your case, you will need to require the string inflection extensions:

Whenever you run a Rails command, it will potentially set up a bunch of classes before doing the actual work, and unlike many other languages, in Ruby this setup is done by actual Ruby code (this is how DSLs work), and any broken code that runs during that time will prevent any commands from running.

It won't run any instance methods, but any broken class-level code will cause issues.

So the migration thing is just a red herring, presumably all your Rails commands are broken.

According to your stacktrace, app/models/user.rb:8 (which you haven't provided), is getting run during initialisation. Models getting loaded during initialisation is quite common, but in this case that code is breaking.

Looking at the ActiveRecord source code (with less -N `bundle show activerecord`/lib/active_record/persistence.rb and looking at line 138), you seem to be calling the destroy class method (e.g. User.destroy(1)) but without parameters, like you do with the destroy instance method (e.g. User.find(1).destroy). So you should make sure you understand the difference between these two.

I'm not sure why you would be calling User.destroy outside of an instance method, but not having the relevant user model code I cannot say. Is there just a stray "destroy" by itself there?
