@achrinza

@salembenammar I can't really pinpoint why the config worked with your personal account, but was the datasource.json created the same way stated on the project's Github page?

@salembenammar

Thanks to much @achrinza , its working now , the problem was not mentionned on the connector documentation

 Visitor.remoteMethod(

      isStatic: true,
      returns: [

Did anyone have problems when they allowed free form properties, and were gettin errors when trying CRUD operations such as Create/Update, with complains about 'not assignable to type 'DeepPartial<{modelname}>'?

If I remove the [props: string]: any from the model, the error goes away

vikramkh

@vikramkh

Also, is there any way I can make prop more specific?

@madaky Your sample codes do not work

Please advise further.

guys anyone knows if it possible to inject lifecycle observer into service for example with @inject decorator or get from the app context in LB4

Hi everyone, I have a model containing and embedded model that has a one to one relationship (mongodb), and I am having trouble customizing a controller to find the parent object based on the supplied arg = embedded object

has anyone used filterBuilder before from loopback/repositories node module

thomas gooch

@teafg

does anyone have more information on creating custom filters and where clauses within a loopback program?

jomarocas

@jomarocas

hi @teafg is a example of a custom where clauses for filters, you need to connec to collection

  console.log(reaction.where)
  const reacciones = (this.reactionsRepository.dataSource.connector as any).collection("Reactions");
  var collection = await reacciones.aggregate(
    [
      {$match: reaction.where},
      {$group:{_id:"$reactionId", count:{$sum:1}}},
      {$sort:{"count":-1}}
    ]
  ).get();

this if for lb4

thomas gooch

@teafg

@jomarocas awesome thanks!!! I will work with this and try

madaky

@madaky

@jtantwtr_twitter : I reproduce the code , check it is working.... brief about the errors you are getting.

thomas gooch

@teafg

@jomarocas thanks so much, much easier to just reach into the MongoDB operations for customizing. THANKS

any chance anyone has a bit more info on instance introspection when working with MongoDB, save me a lot of time

thomas gooch

@teafg

Anyone have guidance on creating a fairly complex mongodb collection and using instance introspection in a boot script for loopback and have those models automated in creation?

Hi all, is there anyway to make Loopback 3 churn out JWT token instead as access_token?

LB cli tool Vs api connect. What's the difference

Is api connect UI based and a paid version?

thomas gooch

@teafg

Has anyone performed instance-introspection? Creating models via a boot script against a mongodb collection

Diana Lau

@dhmlau

@arunkumar413 , i've asked clarification through google group :)
Are you referring to API Connect v5 or v2018?

@teafg , I'm not familiar with instance-introspection. Assuming you're using LB4, if you want to create a model during boot time, you can try observer: https://loopback.io/doc/en/lb4/Life-cycle.html. I have an article about the usage of observer for some other purpose. https://medium.com/loopback/loopback-quick-tip-seeding-database-using-life-cycle-observer-8ddca55fea5c.

@teafg

https://loopback.io/doc/en/lb2/Creating-models-from-unstructured-data.html

This is led to by https://loopback.io/doc/en/lb4/Connecting-to-MongoDB.html @dhmlau

I will definitely look into the article on medium

Diana Lau

@dhmlau

@teafg are you using LB3 or LB4?

thomas gooch

@teafg

@dhmlau I am using lb4 :smile: thanks so much for the time

I'm having trouble figuring out how to add a type attribute to a SOAP request in LB4.
This is what it is in a working request from a different application:

<change xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:type="ns2:fit_speed"/>

This is what I'm getting, which the SOAP API doesn't accept:

<ns1:change/>

Any ideas?

I need a solution to this in order to implement a top priority feature for a project at work. I have a meeting on Monday where I'm expected to have the feature done.

Diana Lau

@dhmlau

@pilot51 , i got some inputs from @raymondfeng . he mentioned:

can probably use xsi:type attribute
See examples at https://github.com/strongloop/strong-soap/blob/d9eab1bfaa15f10eade2e2f4b719c5815bcfb52a/test/request-response-samples/addList__complex_extension_namespace_for_arrays/request.json#L10

Hi everyone, still looking for the instance-introspection.js for creating classes via a boot script, and I’d be most appreciative

Hi all i'm having troubles to understand lb4 doc in order to change standard port 3000, sorry i'm beginner. Someone that explain it in a simple way please?

madaky

@madaky

@luispozoquerol : Hi, in yuor index.js file at your root loopback application :
port: +(process.env.PORT || 3000), instead of 3000 put your desired port.
