Download the PHP package bytesystems/number-sequence-generator without Composer

BytesystemsNumberGeneratorBundle

This bundle provides an annotation driven approach to generate number sequences for various use-cases, for example for invoices, offers, orders etc. For now it depends on doctrine\orm to store the sequences and doctrine\migrations to prepare your database.

Installation

$ composer require bytesystems/number-sequence-generator\ Prepare your database:\ $ symfony console doctrine:migrations:diff\ $ symfony console doctrine:migrations:migrate

If you don't want to add

No further configuration for the bundle is needed.\ To configure your sequences, use Annotations

Usage

To create a number sequence for an entity, annotate the property, that should be set to the generated number.

Annotation

Add the following use statement to your entity\ use Bytesystems\NumberGeneratorBundle\Annotation as NG;
and annotate the property with:\ @NG\Sequence(key="key",segment="segment",init=1000,pattern="IV{Y}-{#|6|y})

The resulting number will follow the pattern, in this case a generated number might look like: IV2021-004121

string key

mandatory\ Sequences will be generated and persisted automatically for the set key.

string segment

optional\ Offers the possibility to divide a sequence in segments. The segment uses the same values for key, pattern and init, but has its own counter. The segment can be provided as static string or as reference to another property of the entity. To define a reference use segment="{property}".

string pattern

optional, defaults to {#}\ The {#} token is mandatory and will be assumed, if pattern is omitted. The following tokens are available, date components follow PHP's datetime.format.

• {#|L|C} The current number of the sequence. If L is provided, the number will be left-padded with zeroes to length L.\ If C - the date context - is provided, the number will reset on change of context.\ Allowed values for context are (y = year, m = month, d = day, w = week and h = hour).
• {D} Datetime part following datetime.format, allowed values for D are almost all values that produce a fixed length, f.e. d (day of month, 2 digits with leading zero) is allowed, while j (day of month, without leading zeroes) is not. Allowed values:
  • d, day, 2 digits with leading zero
  • D, day, textual 3 letters
  • m, month, 2 digits with leading zero
  • M, month, textual 3 letters
  • y, year, 2 digits
  • Y, year, 4 digits
  • H, hours, 24-hour format, 2 digits with leading zero
  • w, week of year, 2 digits with leading zero (changed to lowercase for consistency)

array segments

optional\ Defines an array of segment annotations with "value" and "pattern" properties. It allows to define a pattern for a segment of a sequence.

int init

optional, defaults to 0\ Defines the inital number for the sequence, the first generated number is initial number + 1.

About Segmentation

It is up to you, to define segmented sequences by yourself and persist them. This gives you flexibility to define dynamic sequences, that rely on another property from your entity.\ It falls back to default sequence unless you explicitly define the sequence manually.

Imagine the entity Product in your application. You want all products to have a number like:\ ACME-5123141-P\ But products from supplier Olymp should have their own article numbers like:\ ZEUS-41313-P\ The annotation achieving your goal would look like:\ Sequence(key="product",segment="{supplierId}",init=1000,pattern="ACME-{#|7}-P")\

This leaves it open to build an interface to mangage sequences and segments.

The resulting entity:

All products will have number like ACME-5123141-P\ Assuming the supplierId of Olymp is 42, enable the Olymp sequence using the following SQL statement:\ insert into bytesystems_number_sequence (sequence, segment, pattern, current_number, updated_at) values ('product','42', 'ZEUS-{#|5}-P',0,now());

If you have more information about segmentation during development, you can extend the annotation.

The segmented sequence can still be modified via sql or an interface, but there's no need to create SQL-statements to crate the segments.

ToDo

• include console command to generate a sequence
• extend segmentation to target multiple properties
