Why did the foreign key constraint fail on the column `postId`? - sql

Why did the foreign key constraint fail on the column: postId? How can I fill the prisma studio with the same postId values?

Error: Exception in HostFunction: Attempting to create an object of type 'sets' with an existing primary key value '6' in react native

I'm trying to store history of workout in realm, my addHistory function looks like this
export function addHistory(workout, exercise, sets, _id) {
console.log({
workout,
exercise,
sets,
_id,
});
if (
_id !== undefined &&
workout !== undefined &&
exercise !== undefined &&
sets !== undefined
) {
// return console.log("HISTORY ", { workout, exercise, sets, _id });
return realm.write(() => {
return realm.create("workoutData", {
_id: _id,
exercise,
workout,
sets,
workoutDate: new Date(Date.now()),
});
});
} else {
alert("History is incomplete");
}
}
Schema of the workoutData is as follows:
exports.workoutData = {
name: "workoutData",
primaryKey: "_id",
properties: {
_id: "int",
workout: "workouts",
exercise: "exercise",
workoutDate: "date",
sets: "sets[]",
},
};
Now when I add sets and click on finishWorkoutHandler the logic works fine before the addHistory function but when addHistory is executed it throws the error as stated in the question.
//finish workout handler
const finishWorkoutHandler = () => {
if (sets.length == 0) {
return;
}
let setsFromRealm = realm.objects("sets");
let workoutData = realm.objects("workoutData");
let setsArray = [];
exercises.forEach((exercise) => {
sets
.filter((items) => items.exercise._id == exercise._id)
.forEach((sets) => {
let _id = 0;
if (setsFromRealm.length > 0) {
_id = realm.objects("sets").max("_id") + 1;
}
addSet(
sets.name,
parseInt(sets.weight),
parseInt(sets.reps),
parseInt(sets.rmValue),
sets.isHeighest,
sets.exercise,
_id,
sets.profile,
sets.failedSet,
sets.warmupSet,
sets.notes
);
let indiSet = {
name: sets.name,
weight: parseInt(sets.weight),
reps: parseInt(sets.reps),
rmValue: parseInt(sets.rmValue),
isHeighest: sets.isHeighest,
_id: _id,
profile: sets.profile,
failedSet: sets.failedSet,
warmupSet: sets.warmupSet,
notes: sets.notes,
createdDate: new Date(Date.now()),
};
setsArray.push(indiSet);
});
let workoutDataId = 0;
let setsArrcopy = setsArray;
console.log("SETS ", realm.objects("sets"));
console.log("SETS ", setsArrcopy);
if (workoutData.length > 0) {
workoutDataId = realm.objects("workoutData").max("_id") + 1;
}
**WORKING AS EXPECTED TILL HERE**
// problem lies here
addHistory(params.workout, exercise, setsArrcopy, workoutDataId);
});
dispatch(setsEx([]));
goBack();
};
the structure of setsArrCopy containing sets is as follows
[
({
_id: 6,
createdDate: 2022-09-29T16:27:06.128Z,
failedSet: false,
isHeighest: false,
name: "Thai",
notes: "",
profile: [Object],
reps: 12,
rmValue: 64,
warmupSet: false,
weight: 56,
},
{
_id: 7,
createdDate: 2022-09-29T16:27:06.151Z,
failedSet: false,
isHeighest: false,
name: "Thsi 3",
notes: "",
profile: [Object],
reps: 10,
rmValue: 75,
warmupSet: false,
weight: 66,
})
];
the logic is also working fine in terms of assigning new ids to the sets being added in a loop. But somehow its throwing error when passing setArrCopy to addHistory function. Although its an array of sets not a single object?

sequelize findandcountall function return same data when using pagination

I am using sequelize: 6.9.0, sequelize-cli: ^6.3.0, express: 4.17.1, pg: 8.7.1
i have a problem when using sequelize findAndCountAll, when i using include other models it will return same data when i'm using paging.
Here is my code for House Table
index: async (req, res) => {
const { page, size, developer, city, priceone, pricetwo, project, isNew } =
req.query;
const { limit, offset } = getPagination(page, size);
try {

if (city) {
filter.cityId = city;
}
if (project) {
filter.projectId = project;
}
if (isNew) {
filter.isNew = isNew;
}
if (priceone && pricetwo) {
const firstPrice = parseInt(priceone);
const secondPrice = parseInt(pricetwo);
if (firstPrice === 100000000 && secondPrice === 100000000) {
filter.price = { [Op.lte]: firstPrice };
} else if (firstPrice === 2000000000 && secondPrice === 2000000000) {
filter.price = { [Op.gte]: firstPrice };
} else {
filter.price = { [Op.between]: [firstPrice, secondPrice] };
}
}

if (HousesData) {

} else {
res.status(200).json({
status: "success",
message: "There is No Data",
data: "No Data",
});
}
} catch (error) {
console.log(error);
return next(
new HttpError(
"Something went wrong, could not get project.",
500,
error
)
);
}
}
my paging function
const getPagination = (page, size) => {
const newPage = page ? page - 1 : 0;
const limit = size ? +size : 10;
const offset = newPage != 0 ? newPage * limit : 0;
return { limit, offset };
};
const getPagingData = (data, page, limit) => {
const { count: totalItems, rows: dataRows } = data;
const currentPage = page ? +page : 1;
const totalPages = Math.ceil(totalItems / limit);
return { totalItems, totalPages, currentPage, dataRows };
};
module.exports = { getPagination, getPagingData };
Let's say i have 10 data
a,b,c,d,e,f,g,h,i,j
if i see first page
http://localhost:3006/api/v1/house?size=5&page=1
it will return a,b,c,d,e (this is right)
and if i see next page
http://localhost:3006/api/v1/house?size=5&page=2
it will return e,d,c,b,a (only reverse not showing f,g,h,i,j)
and if i see all the data it will return correct data
http://localhost:3006/api/v1/house?size=10&page=1
it will return j,i,h,g,f,e,d,c,b,a
but if i disabled
include: [
{ model: Developers, attributes: ["id", "name"] },
{ model: Cities, attributes: ["id", "name"] },
{ model: Projects, attributes: ["id", "name"] },
],
it return the right data when use paging.
my model for House is here
"use strict";
module.exports = {

await queryInterface.createTable("Houses", {

allowNull: false,

};
i also use same paging method on other table. but other table works fine, only this table that got messed up.
the other table named Project function is here for reference
index: async (req, res) => {
const { page, size, developer, city, priceone, pricetwo } = req.query;

How to implement Ngx-Datatable server side pagination if pagination is not zero based

I am trying to implement server-side pagination in angular 5 based web app.
Problem is the API requires pagination to start from index 1 whereas the library "ngx-datatable" pagination is 0 based.
Here's my current implementation:
mycomponent.html
<ngx-datatable
#usersTable
class='material text-centered'
[rows]='users'
[columns]="usersColumn"
[columnMode]="'force'"
[headerHeight]="50"
[footerHeight]="50"
[rowHeight]="'auto'"
[externalPaging]="true"
[offset]="page.offset"
[limit]="page.pageSize"
[count]="page.totalElements"
(page)='fetchList($event)'>
</ngx-datatable>
mycomponent.ts
page: any = {
offset: 0,
pageNumber: 1,
pageSize: 10,
totalElements: '',
sortBy: "id",
sortOrder: "desc"
};
ngOnInit() {
this.usersColumn = [
{
name: 'S.NO',
prop: 'sno'
},
{
name: 'First Name',
prop: 'firstName'
},
{
name: 'Last Name',
prop: 'lastName'
},
{
name: 'Email',
prop: 'email',
width: 200
},
{
name: 'Action',
cellTemplate: this.action
}
];
this.fetchList({ offset: 0 });
}
generateSerialNo(pageNo, size, i) {
const index = i + 1;
return pageNo == 1 ? index : (pageNo - 1) * size + index;
}
fetchList(pageInfo) {
this.page.pageNumber = pageInfo.offset + 1;
const { pageNumber, pageSize, sortBy, sortOrder } = this.page);
this.ListService.fetchList(pageNumber, pageSize, sortBy, sortOrder).subscribe(
success => {
if (success && !success['isError']) {
const responseObj = success['responseObject'];
if (responseObj) {
const List = responseObj.content || [];
const { totalElements } = responseObj;
this.users = List.map((item, i) => {
// set serial no. for user in current iteration
const serialNumber = this.generateSerialNo(this.page.pageNumber, this.page.pageSize, i);
return { sno: serialNumber, ...item };
});
this.page.totalElements = totalElements;
}
} else {
this.toastr.error(success['message'], 'Oops!');
}
},
errorResp => {
const error = errorResp['error'];
this.toastr.error(error['message'], 'Oops!');
}
);
Now Say, there's an action column in the table which consists of buttons to block or unblock user which on click calls a function as follows:
blockUnblockUser(toBlock: boolean) {
this.ListService.blockUnblockUser(toBlock, this.selectedUser.id).subscribe(
success => {
if (success && !success['isError']) {
this.fetchList(this.page);
this.utilService.closeModal();
this.toastr.success(success['message'], 'Success!');
} else {
this.utilService.closeModal();
this.toastr.error(success['message'], 'Oops!');
}
},
errorResp => {
const error = errorResp['error'];
this.utilService.closeModal();
this.toastr.error(error['message'], 'Oops!');
});
}
Here's the problem. On page load, I get my list for page number one and page number one is the active page. Now Click on page number 2, in the request param of API this is what goes:
list?pageNumber=2&pageSize=10&sortBy=id&sortOrder=desc
and in response, I get 3 data for page number 2 with 3 items.
Now if I click on the action button to either block or unblock particular user this is what sent in request params:
list?pageNumber=1&pageSize=10&sortBy=id&sortOrder=desc
and in response, I get data based on the page number 1 with 10 items.
but this time the active page in pagination is still "2"?
Please let me know where I am making mistake and how do I fix this. The backend team cannot make the pagination zero-based index for some reason.

How in graphql get last 3 element

How in graphql.js get last 3 created_at element from mysql db table?
I use sequelize.js
Like this:
query: '{
elements(last:3){
id
}
}'
This is my file db.js
const Conn = new Sequelize(/*connection config*/);
Conn.define('elements', {
id: {
type: Sequelize.STRING(36),
primaryKey: true,
allowNull: false
}
});
export default Conn;
This is my file schema.js
const Query = new GraphQLObjectType({
name: 'Query',
description: 'Root query object',
fields() {
return {
elements: {
type: new GraphQLList(Element),
args: {
id: {
type: GraphQLString
}
},
resolve (root, args) {
return Db.models.elements.findAll({ where: args });
}
}
}
}
});
it must be like this;
...
return Db.models.elements.findAll({
limit: 3,
where: args,
order: [['created_at', 'DESC']]
});

Rally Cumulative Flow Diagram with Points

I'm looking to try and do a cumulative flow diagram by story points in rally with their newer API/SDK and found some sample code on their GitHub page RallyAnalytics GitHub
So after some work I have it working to some degree but don't understand or can find any documentation for how to configure this more. It looks like the report being generated is doing count and not the PlanEstimate which I tried to add in fieldsToSum. How can I get it to sum the PlanEstimate field by c_KanbanState and not just give me a count of stories that matched the c_KanbanState for that week? Sample code below minus the minified code from GitHub.
var userConfig = {
title: 'Cumulative Flow Diagram',
debug: false,
trace: false,
// asOf: "2012-11-01", // Optional. Only supply if want a specific time frame. Do not send in new Date().toISOString().

};
$(document).ready(function() {
visualizer = new CFDVisualizer(charts, userConfig, createVisualization);
});
})();
You may be using a slightly older version because the latest doesn't have the fieldsToSum parameter in the config, but you can upgrade the chart to sum PlanEstimate by chaging a few lines in the CFDVisualizer.coffee to this:
#config.lumenizeCalculatorConfig.metrics = [
{f: 'groupBySum', field: 'PlanEstimate', groupByField: #config.kanbanStateField, allowedValues: allowedValues}
]
from:
#config.lumenizeCalculatorConfig.metrics = [
{f: 'groupByCount', groupByField: #config.kanbanStateField, allowedValues: allowedValues}
]
You should probably also change the axis label in the cfd.html.
If this proves too difficult to accomplish (CoffeeScript may be unfamiliar), let me know and I'll post a new version to GitHub.
