I've made mistake : "$" should be in request not "%"

 this request "SELECT COUNT(*) AS `__count` FROM `clients_order_process` WHERE (`clients_order_process`.`step` = 1 AND `clients_order_process`.`step_description` REGEXP '^заказ роутер.$')"  informs that django sends data correctly.

Many thanks,

2. the result of query  SELECT id from Order_process WHERE step_description REGEXP BINARY '^заказ роутера%'; :

Pls, explain, what way do you recommend using raw string?


thanks

Not sure that problem is related to character_set_server due to highest priority of create table option.  I'm using postgres as default.  I'm proposing to check latin chars and turn on mysql debugging  in case of your permission. 

  localization coding  of MySql is  here http://dev.mysql.com/doc/refman/5.7/en/charset-syntax.html

 It will be nice to check your sql by using this http://stackoverflow.com/questions/650238/how-to-show-the-last-queries-executed-on-mysql

 At this moment I propose do next : 

1)  check log for sql request from django to Mysql 

2) execute next sql from mysql :    SELECT id from Order_process WHERE step_description REGEXP BINARY '^заказ роутера%';

 Why are you not using raw string in your regex ?

Many thanks,

Serge

Sergiy,

Thank you for reply

I checked following parameters:

| clients_order_process | CREATE TABLE `clients_order_process` (
  `id` int(11) NOT NULL AUTO_INCREMENT,

  `order_id` int(11) NOT NULL,

8 rows in set (0,01 sec)


so, I found  | character_set_server     | latin1 
is this the problem?

Try to check this via mysql shell. It will be nice to know codepage at system, database and django project. Have you checked this with Latin charset already ?

Hi,

Someone please, help to resolve my problem with iregex !

using Django 1.9
mysql Server version: 5.7.13-0ubuntu0.16.04.2 (Ubuntu)
python 2.7

I got the record in mysql in table Order_process:

| id  | step | step_description          | date_step           | order_id | manager_id |
+-----+------+---------------------------+---------------------+----------+------------+
| 241 |    1 | заказ роутера             | 2016-08-21 11:03:16 |      170 |          1 |
+-----+------+---------------------------+---------------------+----------+------------+
 
next, I'd like to get thi record by queryset:
    str_iregex = '^заказ роутер.$'
    orders = Order_process.objects.filter(step_description__iregex = str_iregex , step = 1).order_by('-id')

But the got no result.
