Elasticsearch: Copy Index Structure


Use Case: Let's say, you already have an index on one Server1 and you want to create a new index with the exact structure on Server2. What you should do?

Solution: 

1. Copy the index structure from Server1. Let's say your index name is: product-data-index and you can access the settings here: https://x.x.x.x:9200/product-data-index/_settings

{
"product-data-index": {
"settings": {
"index": {
"routing": {
"allocation": {
"include": {
"_tier_preference": "data_content"
}
}
},
"number_of_shards": "5",
"provided_name": "product-data-index",
"max_result_window": "30000",
"creation_date": "1627383249968",
"analysis": {
"normalizer": {
"lowercaseNorm": {
"filter": [
"lowercase",
"asciifolding"
],
"type": "custom"
}
},
"analyzer": {
"comma_analyzer": {
"filter": [
"lowercase"
],
"pattern": "(,)",
"type": "pattern",
"tokenizer": "standard"
}
}
},
"number_of_replicas": "1",
"uuid": "cftuOgIPSKWONmbqfICH0w",
"version": {
"created": "7060299"
}
}
}
}
}

Copy this settings JSON

2. Clean the settings JSON.

Now before creating an index, you have to remove few fields from the above JSON

"product-data-index"
"uuid"
"version"
"
creation_date"

and it should look like this.

{
"settings": {
"index": {
"routing": {
"allocation": {
"include": {
"_tier_preference": "data_content"
}
}
},
"number_of_shards": "5",
"max_result_window": "30000",
"analysis": {
"normalizer": {
"lowercaseNorm": {
"filter": [
"lowercase",
"asciifolding"
],
"type": "custom"
}
},
"analyzer": {
"comma_analyzer": {
"filter": [
"lowercase"
],
"pattern": "(,)",
"type": "pattern",
"tokenizer": "standard"
}
}
},
"number_of_replicas": "1"
}
}
}
}

3. Run this command on Server2 in postman as per the screenshot. You can use any other API Client
which can help you to create the index. You can also use curl.



That's it.


NOTE: To copy data from Server1 to Server2, you can use Reindex API


Thanks!!! Enjoy Programming :)

Odoo/OpenERP: one2one relational field example

one2one relational field is deprecated in OpenERP version>5 but you can achieve the same using many2one relational field. You can achieve it in following two ways : 1) using many2one field in both the objects ( http://tutorialopenerp.wordpress.com/2014/04/23/one2one/ ) 2)  using inheritance by deligation You can easily find the first solution with little search over internet so let's start with 2nd solution. Scenario :  I want to create a one2one relation between two objects of openerp hr.employee and hr.employee.medical.details What I should do  i. Add _inherits section in hr_employee class ii. Add field medical_detail_id in hr_employee class class hr_employee(osv.osv):     _name = 'hr.employee'     _inherits = {' hr.employee.medical.details ': "medical_detail_id"}     _inherit = 'hr.employee'         _columns = {              'emp_code':fields.char('Employee Code', si

Odoo: Download Binary File in v10

To download any binary file in Odoo10 following is the link: http://127.0.0.1:8069/web/content?model=<module_name>&field=<field_name>&filename_field=<field_filename>&id=<object_id> module_name    - the name of the model with the Binary field field_name         - the name of the Binary field object_id            - id of the record containing particular file. field_filename    - name of a Char field containing file's name (optional). So if you want to call a function on button click and download the file, code is as follow: file_url = "http://127.0.0.1:8069/web/content?model=<module_name>&field=<field_name>&filename_field=<field_filename>&id=<object_id>" return {     'type': 'ir.actions.act_url',     'url': file_url,     'target': 'new' } In Reports or web page, you can use it as: <t t-foreach="files&qu

Odoo/ OpenERP: Customize one2many relational field

I was working on one2many relational field to integration one functionality. Worked on python code and then wrote an xml file for the same. Restarted my server. It showed me the row with headers and 'Add an item' button. When clicked on that it opened a pop-up to provide inputs. It shows all the fields with in sequence of it's own. Q1. I need input fields in other sequence or don't need all fields. A.   In xml you would have wrote code like this : <field name="dirtyhandsphp" widget="one2many_list" colspan="4" nolabel="1"> <tree string="Details">              <field name="field1" />              <field name="field2" />                      ---------------------------------------------              <field name="designation" />         </tree>                                                     </field> Add form section inside and
