QUESTION
Im building a Rails API. All my devise routes working fine, execpt for one : the logout.
I followed this tutorial : https://jameschambers.co.uk/rails-api
I already tried few things, like :
- tried the api/logout.json route
- tried to change rb #111 for : config.skip_session_storage = [:http_auth, :params_auth] ( config/initializers/devise.rb )
- tried to change rb #280 for : config.sign_out_via = :get ( config/initializers/devise.rb )
Im sending a DELETE request on this address : localhost:3000/api/logout, with a JWT/Bearer token.

Answered 2021-Sep-02 at 23:12The error ERROR: column jwt_denylist.exp does not exist indicates it's looking for a column (exp) that doesn't exist on the jwt_denylist table.
Your schema shows you have an expired_at but no exp column.
From the jwt-denylist gem the schema it expects exp. Perhaps the tutorial is out of date? Here's what the gem's documentation recommends:

I have cloned an existing project and trying to run it in my system. Since this is the first time I don't have any Gemfile.lock file in my directory. I tried running bundle install and the following errors occur:

Answered 2021-Apr-10 at 18:06In your project directory, try installing rails gem install rails -v 4.1.6 and removing the version from the failing gems like (liquid_markdown, gon, etc..) then try running bundle update then bundle clean --force
I think this might be an issue because all the version of these gems are locked inside your Gemfile
QUESTION
I am creating a Login form in JavaScript and am trying to send this form to my Ruby on Rails backend.
I have two problems:
When the form loads, it triggers the eventListener and sends the blank form's data to the backend. I have e.preventDefault() commented out in the second function below because I kept getting the error that it is not a function. Note: in the backend for Rails, I get the following message when I type in params. "Permitted: false" concerns me.
"sessions", "action"=>"create", "session"=>{}} permitted: false>When I fill in the form with an email and password and click the submit button, the loginData (from
loginButton.addEventListener("submit", submitLogin(loginData)submits a blank value for the email and 'password' for the password (which are the default values I set to test the values) even though these elements are filled in in the form with an actual email address and password.
Function loading login form (note: this loads just fine):
...ANSWER
Answered 2021-Feb-19 at 02:43Your form is submitting automatically because of the way you've set the event handler. The .addEventListener() API requires a reference to a callback function as the second argument. But you passed a function call with arguments like this:
loginButton.addEventListener("submit", submitLogin(loginData));
You have two choices to fix this:
- Pass a reference.
- This will require
loginDatato be available to the handler in some other fashion.
- This will require
loginButton.addEventListener("submit", submitLogin);
- Enclose the call within a function expression:
loginButton.addEventListener("submit", ()=>submitLogin(loginData));
Option 2 is generally preferred when needing to pass parameters to the handler. But you'll see below, for you, option one is the way to go.
The leads to the next problem - submitLogin() function itself.

Problemat runtime the container does not have access to the rails command

...ANSWER
Answered 2021-Feb-06 at 20:58Ruby applications generally use a tool called Bundler to manage their application's dependencies. If your application depends on the rails gem, which provides a rails executable, that will often be in vendor/bin/rails or somewhere similar, but not on the standard $PATH.
The quickest way to make this work is to use the bundle exec wrapper, which knows how to set up paths accordingly.
QUESTION
I am setting up my Rails API server following this tutorial: building-awesome-rails-apis-part-1
Everything works well, except the part that mentions that it is not necessary to indicate the namespace in the route. Eg.
Now our URls look like:
http://api.example.com/v1/peopleor justhttp://api.example.com/peopleif you don’t use the version, it doesn’t interfere with your regular people routes, and it looks great.
When I call http://api.mydomain.com/v1/therapists/ it works, but when I try to omit the v1 namespace in the URL it's not working, do I need to do any extra configuration?
I'm using Rails 6.0.3.4
This is my specific routes.rb file:
...ANSWER
Answered 2020-Nov-05 at 19:30If you omit the v1 namespace in the URL, you must also remove it from your routes.rb file.
The quote from the tutorial stated "or just http://api.example.com/people if you don’t use the version", meaning if you don't include the v1 namespace in the routes.rb file.
QUESTION
I am trying to implement a follow/unfollow function in a react rails-api web application. Currently the follow and unfollow post/delete just fine when I click the follow/unfollow button.
However, whenever a user visits another users page it will follow/unfollow when the page loads without clicking the follow/unfollow button. I do not understand why this is happening since I have, for my post/delete, the useEffect second param set to go off when the state for my follow/unfollow changes.
Please help me figure out why this is happening and how to prevent this. Let me know if more information is needed.
