Cannot set property 'doc' of undefined

[rashidshkh]

When i use sails-swagger it says :- error: The bootstrap function threw an error after its callback was called :: Ty peError: Cannot set property 'doc' of undefined. Do you have any documentation about how to implement.

I dig more into code and found this.sails.hooks.swagger get undefined in node_modules\sails-swagger\dist\api\hooks\swagger\index.js

[jekiii]

I experienced the same issue. The hook was loaded successfully but was not added to sails.hooks.

[tjwebb]

Sorry, updating documentation. This hooks currently works only with sails master

[yankeeinlondon]

Will this make its way into v0.11? I'm not really sure on the timetable for v0.12 and happy to start on 0.12 if it's a relatively mature beta.

[tjwebb]

0.12 is in "release candidate" stage at the moment. I'm running it in production in a couple of places.

[yankeeinlondon]

I'm running into problems getting it running with handlebars templates so for now I've reverted to 0.11.1; how painful is the migration to 0.12.x?

[tjwebb]

The upgrade path to 0.12 should be pretty painless. Can you file a more specific issue in the Sails repo?

[yankeeinlondon]

@tjwebb, sure will do. thanks for your feedback here.

[Glavin001]

Is there migration from v0.11.x to v0.12.x instructions?

I am really excited to use sails-swagger however it is erroring with this issue.

[drewlio]

Following. Just got the same thing on 0.11.2 and 0.12.0-rc3.

[AlexisNo]

Works on master for me, but not 0.12.0-rc3

[devildeveloper]

sails is now on 0.11.2 as master, and i have te same error

[muhammadghazali]

Got the same error here:

[Masquer]

This hook currently works only with sails 0.12

[kevinblanco]

Any update on this ? I get the same error using 0.11.2 and 0.12.

[AlexisNo]

The problem seems to be about the name of the hook. The hook itself assume it is sails.hooks.swagger, but with 0.12.0-rc3, it seems that the name is not cleaned and the hook is available as sails.hooks['sails-swagger']. Using the master branch of Sails, the hook is correctly loaded.

You can change the way sails loads an installable hook to load the hook correctly with 0.12.0-rc3. I didn't test it with 0.11.x.

// config/installedHooks.js
module.exports.installedHooks = {
   "sails-swagger": {
      // load the hook into sails.hooks.swagger instead of sails.hooks['sails-swagger']
      "name": "swagger"
   }
};

Then you can load the swagger document at http://127.0.0.1:1337/swagger/doc/

Edit You may have to create this file too (Inspired by the permissions-api generator) to access to the hook's actions

// api/controllers/SwaggerController.js

var _ = require('lodash');
var _super = require('sails-swagger/dist/api/controllers/SwaggerController');

_.merge(exports, _super);
_.merge(exports, {

    // Extend with custom logic here by adding additional fields, methods, etc.

});

[svenarndt]

I had to create both files in my project directory. In order to get it to run, I had to install lodash (npm install lodash --save)

[lucj]

@AlexisNo I have added both files you described (and also installed lodash). Swagger spec is available form http://localhost:1337/swagger/doc but how do you use swagger-ui then ?

[AlexisNo]

Swagger UI is not part of sails-swagger.

From the Swagger UI README file:

Swagger UI is a dependency-free collection of HTML, Javascript, and CSS assets that dynamically generate beautiful documentation and sandbox from a Swagger-compliant API. Because Swagger UI has no dependencies, you can host it in any server environment, or on your local machine. swagger-ui is independent.

You can quickly have a Swagger UI app running on your local environment using docker

docker build -t swagger-ui-builder .
docker run -p 127.0.0.1:8080:8080 swagger-ui-builder

This will start Swagger UI at http://localhost:8080. By default, CORS should be correctly configured for this address. But I think the current NPM version does not include it. You'll have to configure it yourself in your project.

// config/routes.js
module.exports.routes = {
  '/swagger/doc': {
    cors: {
      origin: 'http://localhost:8080',
      methods: 'GET,OPTIONS,HEAD'
    },
    controller: 'SwaggerController',
    action: 'doc'
  }
}

Also, use config/swagger.js to configure the address where http://localhost:1337/swagger/ui will redirect.

// config/swagger.js
module.exports.swagger = {
  /**
   * require() the package.json file for your Sails app.
   */
  pkg: require('../package'),
  ui: {
    url: 'http://localhost:8080'
  }
};

[lucj]

Thanks a lot for the details answer ! Got it working :)

[adrien-candiotti]

I got a problem with the CORS, even after doing what you said : the Access-Control-Allow-Origin header coming from my sailsjs app is empty, i can't find anything online.

[lucj]

@adrien-candiotti I also have this problem so I copied the swagger-ui elements in an assets/docs folder instead, so ui is on the same machine/port. It seems I did not manage to setup the CORS correctly.

[moisesrodriguez]

@adrien-candiotti @lucj the problem with CORS is the config is hard coded https://github.com/tjwebb/sails-swagger/issues/13. I believe the issue has been fixed in further commits in master, but a new released version has not been added to npm to publish the fix

[lucj]

@moisesrodriguez Hi, thanks a lot for the update.

[manodupont]

So i read all the thread and was wondering if there was a fix for Sails v0.11.3. ?

Thanks.

[tjwebb]

I merged https://github.com/tjwebb/sails-swagger/pull/18, I just need to publish to npm. You can use master for now

[lucj]

Thanks a lot Travis !

@AlexisNo I did the steps as you have said but I am not getting the swagger Ui but only the json format document . I didn't understand the docker part please help me @lucj

[moisesrodriguez]

@tjwebb would you mind publishing to npm. I'm getting this error on sails 0.12.0-rc4 and when I try to use master by doing this on my package.json "sails-swagger": "git://github.com/tjwebb/sails-swagger.git", it says it cannot find the module even thought it there.

[ralberts]

Thanks @AlexisNo and @lucj - I was able to get it all running with your instructions! Now I need to figure out how to have the swagger-ui allow me to edit the post/put directly in swagger-ui like the demo.

@tjwebb I look forward to the npm push as well. Let me know if I can help.

Since I am not running off master for either project. I combined comments from this thread and hope it helps others: 1) npm install --save lodash ( thx @svenarndt ) 2) Created the controller

// api/controllers/SwaggerController.js

var _ = require('lodash');
var _super = require('sails-swagger/dist/api/controllers/SwaggerController');

_.merge(exports, _super);
_.merge(exports, {
  // Extend with custom logic here by adding additional fields, methods, etc.
});

3) Created the installHooks.js

// config/installedHooks.js
module.exports.installedHooks = {
  "sails-swagger": {
    // load the hook into sails.hooks.swagger instead of sails.hooks['sails-swagger']
    "name": "swagger"
  }
};

4) Create swagger.js hook:

// config/swagger.js
module.exports.swagger = {
  /**
   * require() the package.json file for your Sails app.
   */
  pkg: require('../package'),
  ui: {
      url: 'http://swagger.balderdash.io'
  }
};

5) Downloaded swagger-ui and copyied the dist/ contents to assets/docs under my current webapp as @lucj did. I am sure the docker way works well but I didn't try it as I wanted it all under the same app. 6) Done. (At least I hope I got everything).

[talamaska]

@ralberts thanks for your summary, the only thing I did not get is how to navigate to /assets/docs to actually open the swagger.io on local server.

[blanco217]

@ralberts Thanks for your explination it helped me get the ui up and running.

@talamaska you will go to http://localhost:1337/docs

[ronsuez]

does anyone knows how to enable POST/PUT requests from the local swaggerUI?

[pankajdaffodil]

Please let me know how can I send data in query string?
