run automigrate before calling a mongodb database about api-extended-database-khyati

[khyati0212]

I saw it in testing Issue and am going through it. Working on Promises, ES6, testing from the article.

[khyati0212]

Go on. We will find a fix if it gets broke.

[khyati0212]

Now uploaded code for first step of comment #8.
Will work on second step and let you know sooon

[khyati0212]

Please send me sample details.

@khyati0212 we have trobules with Ian on this thing, so don't worry if something will be broken.
if i cannot reply fast, dont' spend a lot of time, cause i think this part should be configured more gentle.
So i ithink i should be with you, while you're working on this task.

[khyati0212]

Yeah sure. I am still learning Mongo and Raven.
Got stuck with assignment of my certification. Was having final submission of this quarter on thursday.
I will finish this in 2 days for sure.

[atherdon]

it's ok - i know that new things is always not easy. Btw, if you're busy - please take your time. it's not a big deal to take some days without coding this project. this will also give me some time :)
and good luck with your assignment!

Hi @atherdon I added automigration. But getting mongo : Authentication fail error. Can you check if I am missing something. Here is the full error log.

sudo npm start

node .

Connection fails: MongoError: Authentication failed.
It will be retried for the next request.

Hi @atherdon did you get chance to look at it?

[atherdon]

no, today i was playing and working with wood - it's clear my mind

[khyati0212]

Ok. Np.

[atherdon]

as i still hiding - don't want to waste your time waiting. if you have spare time, please check this article. Put all things in one place. it was created for you https://medium.com/p/things-that-should-read-and-use-javascript-intern-at-groceristar-april-18-collection-bd6541e9ae28

[atherdon]

ohh, you tracking me :) just joking. yeah it was a task where i keep my draft.

[atherdon]

Some information about migrations:
first part
it's a simple thing, you just need to call automigrate and specify tables that you need to drop.
and you need to run that script from CLI

second part is complex and related to importing data from js array into db row.

1. will be to create a file/files, with arrays(you can grab that data from db.json file)
2. then you'll need to create a file where you'll actually import data from array into db.
   as before - you should check the latest version at search-api - and see how i did it here.

btw, i think your issue related to something else, so i'm cloning your repo and will take a look right now

[atherdon]

as i told you before, mongo is the weakiest part of that tutorial. you should try this version:
https://github.com/GroceriStar/groceristar/blob/master/server/datasources.json

btw, i think there was a different names of datasources, but maybe it'll be solved after update
i got this
A datasource is created with name "reservationDS", which is different from the name in settings ("reservationsDS"). Please adjust your configuration to ensure these names match.

[atherdon]

btw, be brave - i'm trying to broke your current git workflow. let's see how you'll solve it :)

[atherdon]

buzz me if new configuration will not solve the error.

[khyati0212]

should I merge the pull request you created?

[atherdon]

yes, if you reviewed the changes and it's ok

[khyati0212]

Previous error got resolved. In model-config.json datasource name was wrong.

[khyati0212]

but now new error is coming. Mongo authentication is failing.

[atherdon]

will check it soon

[khyati0212]

@atherdon can you try running the app on your system? I think the error is related to mongo connection. I did so much research. Tried installing heroku on local system an other things as well but nothing helped.

[atherdon]

@khyati0212 check in it right now

[atherdon]

not sure, but maybe this comment was missed: #8 (comment)
if you compare 2 datasources - you'll see the difference.
not a big deal - i was trapped with same issue :) this is why i use mlab and simple version of connector

will try to update datasources on my PC and connect.

[atherdon]

works for me

[khyati0212]

Did you change anything? Or run the code from this repository?

[atherdon]

If i was you:

1. i'll re-read this comment #8 (comment)
2. compare 2 datasources
3. update your datasource
4. paste mlab link from this issue: #5
5. run your project, find maybe(or not) another small issue(that you know how to deal with)
6. profit :)

[khyati0212]

Great. Thank you for guidance. I will do that.

[atherdon]

no prob. it's just bad tutorial coverage. maybe i need to recreate it, in order to skip that stuff, confusing parts...

soon it will be less buggy. i mean it will be more easy to catch.

[khyati0212]

finally it worked. what a relief. I understood. Used id and password not specified so authentication was failing. now moving to part 2. :|

[atherdon]

i don't want to steal that feeling from you. but i steal it from Ian - helped him with some small issue.. hope he'll didn't findout :) On 13-Apr-2018 at 04:45 PM, Khyati wrote: finally it worked. what a relief. — You are receiving this because you were mentioned.

[atherdon]

still, you didn't do it well. please re-read again that comment related to datasources.

[khyati0212]

no no i haven't updated the code yet on git
let me do it. After that i will do second step of that comment

[atherdon]

will close this task, and move info into migration into another

[atherdon]

got it. btw, it's good that you catched the name of datasource in migrate file. i got that as error frequently On 13-Apr-2018 at 07:00 PM, Khyati wrote: no no i haven't updated the code yet on git let me do it.
