I am getting this error, "An error has occurred, this and all later migrations canceled: SQLite3::SQLException: no such table: users". Not sure what to do? I think i followed an old video of yours in rails 6 where we built the authentication manually. But now I had the users table, so I couldn't migrate the devise database. So then I tried to delete the other data base: rails db:drop. and now I get the above error and can't find any stack overflow guides to help.

I have a question, does there need to be a relationship from the blog to the user for a user to edit their post, or can the ID created by Devise be added to the blog table to filter it? If there isn't a rule that ensures only I can edit my posts, anyone else could potentially edit them

[@GorailsTV]

Keep watching. 😜

[@GabrielMartinez-ez9ue]

Would you recommend having a look first at the rails 6 course that you have? As I see you implemented manually your built auth not using devise

[@GorailsTV]

We recommend Devise for actual use and building auth from scratch at least once to understand how Devise works.

[@DanielJacksonNor]

Fantastic content, as always. Do you have videos for alternatives to Devise?

[@wlaidkabou]

why do you think you need alternatives to Devise, what devise couldn't provide?

[@user-yy5ru6xh3y]

I just don't understand how we are able to access user_signed_in? method so easily ? There must be something calling that method right ?

[@wlaidkabou]

Devise gem handles that for you. without devise you can't check if user signedin or not.

[@wlaidkabou]

that's one of the devise gem power, for sure devise Is the best gem ever

[@kev_G]

Why does the logout button need to be a button? I tried making it a link but got an error [No route matches [GET] "/users/sign_out"]

[@GorailsTV]

Because it is a DELETE request and browsers use forms for that. Links only make GET requests.

@@GorailsTV ahh ok that makes sense. Thanks!!
