I'm new to datamapper. I have a problem on trying to duplicate a result into a new id.
This is a simplified table for my database:
Job Table
| id | property_id | name | type |
| 1 | 1 | abc | i |
| 2 | 2 | def | ii |
Property Table
| id | job_id | size |
| 1 | 1 | 90 |
| 2 | 2 | 40 |
How can I automatically duplicate a new job based on job id 1 into new job/property id like
Job Table
| id | property_id | name | type |
| 1 | 1 | abc | i |
| 2 | 2 | def | ii |
| 3 | 3 | abc | i |
Property Table
| id | job_id | size |
| 1 | 1 | 90 |
| 2 | 2 | 40 |
| 3 | 3 | 90 |
Thanks for helping! :)
In the documentation for DataMapper Overzealous Edition: http://datamapper.wanwizard.eu/pages/clonecopy.html There's clone and copy, copy will clear the id. Here's their example, just skip the part of making changes:
// Let's save a new hosting plan
$p = new Plan();
$p->name = 'The 100GB Plan';
$p->storage = 1000;
$p->bandwidth = 2000;
$p->databases = 5;
$p->domains = 5;
$p->emails = 50;
$p->save();
// Now, lets make a copy of that saved plan and base a new one off of it
$p = $p->get_copy();
// Change only what we need to
$p->name = 'The Big 150GB Plan';
$p->storage = 1500;
$p->bandwidth = 2500;
// And now save a new record
$p->save();
You can also just modify the object you retrieve, and then use save_as_new() to save it as a new record.

I have situation like this, I want to get value from database(this values used comma delimited) from more than one rows based on month and year that I choose, for more detail check this out..
My Schedule.sql :

In my website I want to make calculation with those two table. So if in my website want to see start from date 2020-10-01 until 2020-11-01 for total amount between those date, I try to show it with this code :
Output example
+----+-----------+-----------+---------+
|No |Date Start |Date End |T.Amount |
+----+-------- --+-----------+---------+
|1 |2020-10-01 |2020-11-01 |$ 45 | <= this amount came from $5+$7+$5+$7+$5+$9+$7
+----+-------- --+-----------+---------+
Note :
Date Start : Input->post("A")
Date End : Input->post("B")
T.Amount : Total Amount based input A and B (on date)
I tried this code to get it :
<?php
$startd = $this->input->post('A');
$endd= $this->input->post('B');
$chck = $this->db->select('Do_skill')
->where('Activ_date >=',$startd)
->where('Activ_date <',$endd)
->get('Schedule')
->row('Do_skill');
$dcek = $this->Check_model->comma_separated_to_array($chck);
$t_amount = $this->db->select_sum('price')
->where('Date_skill >=',$startd)
->where('Date_skill <',$endd)
->where_in('Skill',$dcek)
->get('skillqmount')
->row('price');
echo $t_amount; ?>
Check_model :
public function comma_separated_to_array($chck, $separator = ',')
{
//Explode on comma
$vals = explode($separator, $chck);
$count = count($vals);
$val = array();
//Trim whitespace
for($i=0;$i<=$count-1;$i++) {
$val[] .= $vals[$i];
}
return $val;
}
My problem is the result from $t_amount not $45, I think there's some miss with my code above, please if there any advice, I very appreciate it...Thank you...
Your first query only return 1 row data.
I think you can do something like this for the first query.
$query1 = $this->db->query("SELECT Do_skill FROM schedule WHERE activ_date >= $startd and activ_date < $startd");
$check = $query1->result_array();
$array = [];
foreach($check as $ck){
$dats = explode(',',$ck['Do_skill']);
$counter = count($dats);
for($i=0;$i<$counter;$i++){
array_push($array,$dats[$i]);
}
and you can use the array to do your next query :)
The array $dcek has the values
Accountant,Medical,Photograph
The query from Codeigniter is
SELECT SUM(`price`) AS `price` FROM `skillqmount`
WHERE `Date_skill` >= '2020-10-01' AND
`Date_skill` < '2020-11-01' AND
`Skill` IN('Accountant', 'Medical', 'Photograph')
which returns 17 - this matches the first three entries in your data.
Your first query will only ever give one row, even if the date range would match multiple rows.
I have 2 tables and a third pivot table as follows:
Table 1: Files
id
title
Table 2: Pools
id
title
is_visible (1,0)
Table 3: file_pools
file_id
pool_id
All Models and Relationships are in place.
A File may belong to none, 1 or more pools
A Pool may have none,1 or more files
Now, i would like to create a scope visible in the Model File such that:
the query includes any File that belongs to none or 1,or more active Pools
should not include any File that has at least 1 invisible (is_visible=0) Pool, even if this File belongs to another visible Pool
Below is what I have tried but this includes files that are both in visible and invisible Pools
public function scopeVisible($query)
{
return $query->doesntHave('pools')->orWhereHas('pools', function ($query) {
$query->where('is_visible',1);
});
}
any help highly welcome
EDIT: Add Sample Data
table: files
| id | title |
|----------|---------------|
| 1 | File A |
| 2 | File B |
| 3 | File C |
| 4 | File D |
table: pools
| id | title | is_visible|
|----------|---------------|---------- |
| 1 | Pool 1 | 1 |
| 2 | Pool 2 | 0 |
table: file_pools
| file_id | pool_id |
|----------|---------------|
| 1 | 1 |
| 2 | 2 |
| 3 | 1 |
| 3 | 2 |
The Expected Result : (scope:visible)
| id | title |
|----------|---------------|
| 1 | File A |
| 4 | File D |
Hope this clarifies
If I understand your situation correctly:
public function scopeVisible($query)
{
return $query->whereDoesntHave('pools', function ($query) {
$query->where('is_visible', 0);
});
}
Here i have two tables
Table One
+---------------+----------+------------+
| Raw Material | Size | Qty |
+---------------+----------+------------+
| A | 1 | 5 |
| A | 2 | 2 |
| A | 1 | 2 |
| B | 0 | 5 |
| B | 0 | 1 |
+---------------+----------+------------+
Table Two
+---------------+----------+------------+
| Raw Material | Size | Qty |
+---------------+----------+------------+
| A | 1 | 2 |
| A | 2 | 1 |
| A | 1 | 1 |
+---------------+----------+------------+
I want out put like
+---------------+----------+------------+
| Raw Material | Size | Qty |
+---------------+----------+------------+
| A | 1 | 4 |
| A | 2 | 1 |
| B | 0 | 6 |
+---------------+----------+------------+
Want to get substract first two tables sum of qty by grouping Rawmaterial and Size
Something like this should do the job
var result = tableA.Select(e => new { Item = e, Factor = 1 })
.Concat(tableB.Select(e => new { Item = e, Factor = -1 }))
.GroupBy(e => new { e.Item.RawMaterial, e.Item.Size }, (key, elements) => new
{
RawMaterial = key.RawMaterial,
Size = key.Size,
Qty = elements.Sum(e => e.Item.Qty * e.Factor)
}).ToList();
First we create a union of the two tables using Concat, including the information which one is additive (in Factor field), and then just do the normal grouping.
If you want the result to be List<YourTableElementType>, just replace the final anonymous type projection (new { ... }) with new YourTableElementType { ... }.
i need help with a query, can't get it to work correctly. What i'm trying to achieve is to have a select box displaying the number of records associated with a particular theme, for some theme it works well for some it displays (0) when infact there are 2 records, I'm wondering if someone could help me on this, your help would be greatly appreciated, please see below my actual query + table structure :
SELECT theme.id_theme, theme.theme, calender.start_date,
calender.id_theme1,calender.id_theme2, calender.id_theme3, COUNT(*) AS total
FROM theme, calender
WHERE (YEAR(calender.start_date) = YEAR(CURDATE())
AND MONTH(calender.start_date) > MONTH(CURDATE()) )
AND (theme.id_theme=calender.id_theme1)
OR (theme.id_theme=calender.id_theme2)
OR (theme.id_theme=calender.id_theme3)
GROUP BY theme.id_theme
ORDER BY theme.theme ASC
THEME table

Thanking you in advance
I think that themes conditions should be into brackets
((theme.id_theme=calender.id_theme1)
OR (theme.id_theme=calender.id_theme2)
OR (theme.id_theme=calender.id_theme3))
Hope this help
I'm trying to produce a web page report of Orders Per Customer with line item details for each order.
So it looks like this:
Customer 1 | Order 1 | Item 1 |
| | == New Row == |
| | Item 2 |
| | == New Row == |
| | Item 3 |
| | == New Row == |
| ====== New Row ========= |
| Order 2 | Item 1 |
| | == New Row == |
| | Item 2 |
| | == New Row == |
| | Item 3 |
| | == New Row == |
| ====== New Row ========= |
| Order 3 | Item 1 |
| | Item 2 |
== New Row ==============================
Customer 2 | Order 1 | Item 1 |
| | == New Row == |
| | Item 2 |
| | == New Row == |
| | Item 3 |
| | == New Row == |
| | Item 4 |
| | == New Row == |
| | Item 5 |
| | == New Row == |
| ====== New Row ========= |
| Order 2 | Item 1 |
| | == New Row == |
| | Item 2 |
| | == New Row == |
| | Item 3 |
== New Row ==============================
Is it better to get an array list of data as follows:
1 | 1 | 1 |
1 | 1 | 2 |
1 | 1 | 3 |
1 | 2 | 1 |
1 | 2 | 2 |
1 | 2 | 3 |
1 | 3 | 1 |
1 | 3 | 2 |
2 | 1 | 1 |
2 | 1 | 2 |
2 | 1 | 3 |
2 | 1 | 4 |
2 | 1 | 5 |
2 | 2 | 1 |
2 | 2 | 2 |
2 | 2 | 3 |
and pass 1 JavaBean and use JSTL to determine the nesting as follows:
this is incomplete for brevity
<table><tr><th>Customer No</th><th>Orders</th></tr>
<c:forEach var="custOrderLineItem" items="${customerOrderLineItemList}">
<c:set var="currentOrder" value="custOrderLineItem.orderId">
<c:set var="currentCustomer" value="custOrderLineItem.customerId">
<c:if test="${currentOrder != custOrderLineItem.orderId}">
==New Row==
</c:if>
or is it better to use nested JavaBeans
Customer.setOrders<List>
Orders.setOrderDetails<List>
OrderDetails.setLineItem<List>
and then use JSTL as such
<c:forEach var="customer" items="${customerList}">
<c:forEach var="order" items="${customer.orderList}">
<c:forEach var="lineItem" items="${order.detailList}">
After spending the time writing this, I feel like the second method looks cleaner and easier. But the first method seems to have an easier SQL query. I'm not using JPA, just basic JDBC sql calls. So how does one populate nested JavaBeans, without JPA? Do you do something like this?
List<Customer> custList = getCustomerList();
ListIterator custListIter = custList.listIterator();
while (custListIter.hasNext()) {
customer = (Customer) custListIter.next();
List<Order> orderList = getOrderList(customer.getId());
ListIterator orderListIter = orderList.listIterator();
while (orderListIter.hasNext()) {
order = (Order) orderListIter.next();
List orderDetailsList<OrderDetail> = getOrderDetailList(order.getId);
order.setOrderDetails(orderDetailsList);
orderListIter.set(order);
}
customer.setOrderList(orderList);
custListIter.set(customer);
}
You could simply make the SQL query which returns everything, and build the graph of objects from the result set. Using maps to keep an association between IDs and the corresponding objects:
Map<Long, Customer> customersById = new HashMap<Long, Customer>();
Map<Long, Order> ordersById = new HashMap<Long, Order>();
Map<Long, Item> itemsById = new HashMap<Long, Item>();
while (rs.next()) {
Long customerId = rs.getLong(1);
Customer customer = customersById.get(customerId);
if (customer == null) {
customer = new Customer(customerId);
// populate other fields of customer
customersById.put(customerId, customer);
}
Long orderId = rs.getLong(5);
Order order = ordersById.get(orderId);
if (order == null) {
order = new Order(orderId);
customer.addOrder(order);
// populate other fields of order
ordersById.put(orderId, order);
}
// same for items
}
At the end of the loop, you have all the customers, each with their orders, each with their items.
