Rolify doesn't work inside engines

[ghost]

I have devise setup inside of my engine, however, the Rolify generates do not work inside the engine.

rails g rolify Role User
error: "uninitialized constant User"

So I then just created the necessary files without the generator. I would then get an error on rake db:migrate stating "uninitialized constant Role".

So I put: require 'rolify'
inside of my engine.rb file.

Still nothing. What's wrong?

you can use this repo https://github.com/mido18/rolify this problem fixed in it.
I requested a merging request let's hope the owner will accept it soon :)

[mido18]

@Svashta i think its still not merged

@mido18 What PR is it? Can you link to it and is it working against the current codebase?

[samuelralak]

I am the same problem here. @mido18 what is causing this problem and what was the fix?

[wldcordeiro]

@mido18 there is no open or closed PR from you here, could you try creating one against the current repo head?

[mido18]

@wldcordeiro Sorry what is PR ? also i don't know if it's working on the current codebase
@samuelralak The fix is in this link

A PR is a pull request, your fix is over a hundred commits behind the Rolify upstream. I could take a look and see if it works with our current code base but if you could pull down changes from upstream and create a pull request it'd help a lot.

[mido18]

@wldcordeiro okay i will try to do it :)

[wldcordeiro]

Hmm it actually looks like I've already integrated your changes into the project at some point but the issue is still present.

@wldcordeiro i think you must pass "engine" and "devise" as args when you use
"rails g rolify Role User" so the generator will be something like this
"rails g rolify Role User engine devise"

[mido18]

@wldcordeiro
I added this to gem documentation on my fork

1. Generate Role Model

First, create your Role model and migration file using this generator:

rails g rolify Role User
if you use rolify inside eninge your generator:

rails g rolify Role User engine
if your user model have devise dependency then your generator:

rails g rolify Role User engine devise

[wldcordeiro]

Ah, I see. That needs to be added to the docs somewhere. 😄 I'll figure that out and add that.

[wldcordeiro]

@samuelralak the solution has been posted if you're on the newest version of Rolify.

[mido18]

@wldcordeiro Cool 👍

@wldcordeiro: can you please point out the commit or the wiki page regarding that issue in order to close it?

Just wanted to let people know that rails g rolify Role User engine devise no longer appears to work. The correct method for ensuring Rolify works within a mounted engine is

1. Add rolify to your gemspec with
   s.add_dependency 'rolify', '~> 5.2'
2. Run the generator as such
   bin/rails generate rolify Role YourEngineName::User
3. Add the following to your user.rb file
   rolify role_cname: 'YourEngineName::Role'
4. Add the following to lib/yourenginename.rb
require 'rolify'

Added Engine configuration steps in wiki, thanks!
