I’m working on a project in react native expo, And i want to Execute a python script inside my react native expo project to run a script, where it will then find a JSON file in my project and use that information to create an excel sheet and email it to the user, that is all it needs to do, I don’t need information to come back to me I just need the file to be executed within my project.

I want to create a connection from an existing Mongo DB collection to an existing Docker container. Can anybody see it out.

I tried out several syntaxes and approaches but It always give me error.
Thanks in advance!

I have the following form.

const MyForm = ({
  myFormRef,
}) => (
  <form id="myForm" ref={myFormRef} method="POST">
    <input name="test_token" type="hidden" />
    <input name="id" type="hidden" />
    <input name="versionId" type="hidden" />
    <input name="additionalId" type="hidden" />
  </form>
);

export default MyForm;

Information from above form is captured here within another component.

[...myFormRef.current.children].forEach((child) => {
    // child.name is 'test_token'
    // child.value is 'some_token'
});

Thus children here is the above data.

children is

{
    test_token: 'some_token',
    id: 'some_id',
    versionId: 'some_version',
    additionalId: 'some_additional_id'
}

I want to modify children to become

{
    token,
    overallData: {
        id,
        versionId,
        additionalId
    }
}

Is it possible to do that?

Closest I found was appendChild() but that is to append a node.

i’m trying to sign in with facebook, but it shows me this message , can someone explain me what ‘s wrong ? i have 2 screenshots for my app settings in facebook developper

I have two arrays of objects that I must combine in one array. If an object is present in both arrays, it should be only once in the final array. If an object is not present in an array, I need to add it with a modified attribute.

Here’s the situation:

const Array1 = [
{value: "id1", name: "Element1", boolean: false}, 
{value: "id2", name: "Element2", boolean: false}, 
{value: "id3", name: "Element3", boolean: false}
]

const Array2 = [
{value: "id1", name: "Element1", boolean: false}, 
{value: "id2", name: "Element2", boolean: false}, 
{value: "id4", name: "Element4", boolean: false}
]

Expected output:

const result = [
{value: "id1", name: "Element1", boolean: false}, 
{value: "id2", name: "Element2", boolean: false}, 
{value: "id3", name: "Element3", boolean: true}, 
{value: "id4", name: "Element4", boolean: true}
]

I wrote some tests, which pass locally, but fail in the pipeline.

Here’s the test:

async displaysMachineTypeWhenOtherMachineIsSelected () {
      const { asFragment } = render(
        FunctionsFactory.componentFactory({ fetchedState: { machine: mockedMachineState } }),
  );

  // Functions is an object. It's used in other tests and they all pass
  await Functions.selectMachineState1();

  Functions.clickEditText();

  await Functions.clickOnSelect(DetailsNames.Category);

  screen.getByText('Other machine').click();

  await waitFor(() => {
    expect(screen.getByText(DetailsLabels.MachineType)).toBeInTheDocument();
  });

  expect(Array.from(document.querySelectorAll('input')).length).toEqual(10);

  expect(asFragment()).toMatchSnapshot();
}

it(
  'should display machine type dropdown when other machine is selected',
  displaysMachineTypeWhenOtherMachineIsSelected,
);

And as I said, it passes locally, but fails in the gitlab pipeline.

Error from gitlab:

Any idea what I’m doing wrong here?

I am building an Expense Tracking app using Node.js where all the Income and Costs should get saved in a database.

My idea is to create a new collection for each registered user and save all their income/cost actions in that collection.

The things i would like to consider before writing it are:

• how do i name the collections
• Efficiency of this method
• is it even secure
• how do i save their data when they login from an another device
• can two users have the same collection name causing them to save their actions in one collection
• are there any better ways to do this

What i came up with to solve it was to make a model which takes the given company/user name to create a collection.

const mongoose = require('mongoose');
const bcrypt = require ('bcrypt');
const Schema = mongoose.Schema;

const UserSchema = new Schema({
    userName: {
        type: String,
        required: true,
        unique: true
    },
    userPass: {
        type: String,
        required: true
    },
    userEmail: {
        type: String,
        required: true,
        unique: true
    }
}, { timestamps: true });

UserSchema.pre('save', async function (next) {
    try {
        const hashed = await bcrypt.hash(this.userPass, 10)
        console.log('saved user with hashed password.')
        this.userPass = hashed
        next();
    } catch {
        next(error)
    }
})

const User = mongoose.model(userName, UserSchema);

module.exports = User;

And that collection can only be accessed by the one who has the password for that unique name.

So what i would like to ask is: Are there any better ways to do this?

I have array of object and I want to convert this to comma separated object.

let arr = [{name:"k"},{name:"p"}];
  console.log(...arr.join(','));

I’m getting this [ o b j e c t O b j e c t ] , [ o b j e c t O b j e c t ]
I want to in this format {name:”k”},{name:”p”}. please help. thanks in advance.

If i add conditions for idle time, it worked when site is opened in single tab. How to resolve it?

I have a Buefy autocomplete field in my project.

<b-field>
    <b-autocomplete
        v-model="client"
        :data="agencyClients"
        field="name"
        @input="setClient"
        :clearable="true"
        open-on-focus
        size="is-small"
    >
    </b-autocomplete>
</b-field>

The v-model property should be the object in form

{id: 10, name: 'AAA'} 

Therefore I use field property in the input which is set to name. This basic set up works well. But if I trigger @input event which looks like

async setClient(clientName) {
    if( clientName ) {
        const client = this.agencyClients.find((item) => item && item.name === clientName);
        if( client ) {
            await this.$store.dispatch(`${this.storeName}/updateClientId`, {clientId: client.id});
            this.client = client;  // Set client as object. 
        }
    }
},

I get and [object] as value in input field. Autocomplete is not able to show client.name value as onload. Why is it so?

The second issue is that with deselect function. It does not trigger @input event. It does not make sence. If I clear the value input event is not triggered? Why?

Can somebody explain me what am I doing wrong? Thanks a lot.

I am receiving a list of comments from a graphql backend in the following format:

[
        {
            "__typename": "Comment",
            "id": "1",
            "userId": "1",
            "postId": "1",
            "parentCommentId": null,
            "content": "test 1"
        },
        {
            "__typename": "Comment",
            "id": "2",
            "userId": "1",
            "postId": "1",
            "parentCommentId": null,
            "content": "this is a comment"
        },
        {
            "__typename": "Comment",
            "id": "34",
            "userId": "1",
            "postId": "1",
            "parentCommentId": "1",
            "content": "reply to test1"
        },
        {
            "__typename": "Comment",
            "id": "35",
            "userId": "1",
            "postId": "1",
            "parentCommentId": "34",
            "content": "nested reply to "reply to test1"nn"
        },
        {
            "__typename": "Comment",
            "id": "36",
            "userId": "1",
            "postId": "1",
            "parentCommentId": "34",
            "content": "test?"
        }
    ]

The comments with parentCommentId === null are the highest level comments, while comments where parentCommentId !== null are replies to a comment where id === parentCommentId

I would like to transform this data structure to something like:

[{
    "__typename": "Comment",
    "id": "1",
    "userId": "1",
    "postId": "1",
    "parentCommentId": null,
    "content": "test1",
    "replies": [{
      "__typename": "Comment",
      "id": "34",
      "userId": "1",
      "postId": "1",
      "parentCommentId": "1",
      "content": "reply to test1",
      "replies": [{
        "__typename": "Comment",
        "id": "35",
        "userId": "1",
        "postId": "1",
        "parentCommentId": "34",
        "content": "reply to test1"
      }]
    }]
  },
  {
    "__typename": "Comment",
    "id": "2",
    "userId": "1",
    "postId": "1",
    "parentCommentId": null,
    "content": "this is a comment",
    "replies": []
  }
]

I have the following function to do the data transformation:

function formatData(comments: Array < IComment > ) {
  let commentList = Array < IComment > ();

  // add comments without `parentCommentId` to the list.
  // these are top level comments.
  for (let i = 0; i < comments.length; i++) {
    if (!comments[i].parentCommentId) {
      commentList.push({ ...comments[i],
        replies: []
      });
    }
  }

  for (let i = 0; i < comments.length; i++) {
    if (comments[i].parentCommentId) {
      const reply = comments[i];
      mapReplyToComment(commentList, reply);
    }
  }


  return commentList;

  function mapReplyToComment(
    commentList: Array < IComment > ,
    reply: IComment
  ): any {
    return commentList.map((comment) => {
      if (!comment.replies) {
        comment = { ...comment,
          replies: []
        };
      }
      if (comment.id === reply.parentCommentId) {
        comment.replies.push(reply);

        return comment;
      } else {
        return mapReplyToComment(comment.replies, reply);
      }
    });
  }
}

However this only works for one level deep into the object tree. so I am getting the replies of a main comment, but replies to replies are not added to the object.

this is what I am getting now:

[{
    "__typename": "Comment",
    "id": "1",
    "userId": "1",
    "postId": "1",
    "parentCommentId": null,
    "content": "test1",
    "replies": [{
      "__typename": "Comment",
      "id": "34",
      "userId": "1",
      "postId": "1",
      "parentCommentId": "1",
      "content": "reply to test1"
      // -- I should have here another node of "replies"
    }]
  },
  {
    "__typename": "Comment",
    "id": "2",
    "userId": "1",
    "postId": "1",
    "parentCommentId": null,
    "content": "this is a comment",
    "replies": []
  }
]

Could you please point out what am I doing wrong and provide some explanation?
Thanks in advance

I am calling another from current component

<Link to={`/${props.certificate.id}/edit` } >Edit</Link>

in the receiving component I am receiving it using props.

export function EditCertificate(props: any)

then I am accepting id as

const {id} = props.match.params;

so in the url below is coming but EditCertificate component is not getting launched.

http://localhost:4200/934108e0-ca73-4837-bbf2-26482ece1cb6/edit

in the route I have defined below.

  <SecureRoute path=":id/edit">
            <EditCertificate id={':id'} />
        </SecureRoute>

what mistake I am doing?

I upgraded the version of Node JS on the project from v12 to v14 and with that some of the packages including laravel-mix.Through-out the project there are these css modules “:global(selector)” being used , that after updating are not working.

I tried adding css-loader as a module in webpack.mix.js:

module: {
        rules: [
            {
                test: /.css$/,
                use : [
                    {
                        loader: 'css-loader',
                        options: {
                            modules: true,
                        }
                    }
                ]
            }]} // there are some other babel rules as well.

After running npm run watch and it compiles it shows this error:

ERROR in ./resources/css/fontello.css (./node_modules/laravel-mix/node_modules/css-loader/dist/cjs.js??clonedRuleSet-7[0].rules[0].use[1]!./node_modules/postcss-loader/dist/cjs.js??clonedRuleSet-7[0].rules[0].use[2]!./node_modules/css-loader/dist/cjs.js??clonedRuleSet-23[0].rules[0].use[0]!./resources/css/fontello.css)

             </tr>
            </table>

And this is Javascript code

 <script type="text/javascript">
                        $(document).ready(function() {
                        
  $(document.body).on("change.select2", "#state",function () {
      var id_country = $(this).val();
      var token = $("input[name='_token']").val();
      $.ajax({
          url: "<?php echo route('select-ajax') ?>",
          method: 'GET',
          dataType: 'json',
          data: {id_country:id_country, _token:token},
          success: function(data) {
            $("select[name='sub'").html('');
            $("select[name='sub'").html(data.options);
          }
      });
  });
                        });
</script>

<script>


let initializeSelect2 =  function() {
  $('.js').select2();
}

var i = 0;
$("#add12").click(function(){
    ++i;
    $("#dynamicTable12").append('<tr><td><select name="addmore['+i+'][ledger]" id="" class="form-control js" required="required"><option value="">--Please select--</option>@foreach($bud as $iit_bank)<option value="{{$iit_bank->id}}">{{$iit_bank->name}}</option>@endforeach</select></td> <td> <select id="state" class="form-control js" name="addmore['+i+'][project]" required="required"><option value="">--select--</option>@foreach($buud as $iit_bank)<option value="{{$iit_bank->id}}">{{$iit_bank->name}}</option>@endforeach</select></td> <td> <select name="sub" class="form-control"><option>-- Sub Head--</option></select></td><td><select name="addmore['+i+'][cr_dr]" id="" class="cr_dr form-control" required="required"><option value="">--select--</option><option value="Dr">Dr</option><option value="Cr">Cr</option></select></td><td><input type="number" name="addmore['+i+'][amount]" placeholder="Amount" class="txt form-control" required="required"/></td><td><button type="button" class="btn btn-danger remove-tr">Remove</button></td></tr>');
    
    initializeSelect2()
});
$(document).on('click', '.remove-tr', function(){  
     $(this).parents('tr').remove();
}); 



$(document).ready(function() {
    initializeSelect2()
});


</script>

And also I want to name the Subhead with an array but it was not working fine

Using Binance API, I want to get my total account balance in BTC (or USD)

I am able to get the spot wallet balance by querying /api/v3/account endpoint.

In my case, the total balance is the SUM of spot wallet + earn wallet.

const totalBalance = spot + earn

With only spot, I am not able to calculate totalBalance nor earn.

Using the Binance API, how can I get the totalBalance or earn?
