I am working on a product importing tool, that imports data through XMLRPC into my Odoo 18 database. I am well on the way, except getting the Attribute lines has some mysteries for me.


I have created an product.attribute​and product.attribute.value​, which are are all OK. Now, to connect this to a product, I have to create a product.template.attribute.line​which has an attribute_id​ and an array of value_ids​. So far so good, however, to prevent creating too many items, I first want to check if such a line already exists. To do so, I have now this:


​existing_line_ids = self.models.execute_kw(self.database, self.uid, self.apikey, 'product.template.attribute.line', 'search', [[["value_ids","any",[value_id]],["attribute_id", "=", attribute_id]]])​


But this gives me an error: 

​ValueError: not enough values to unpack (expected 3, got 1)​


How can I search for a line that has a specific attribute_id​ and value_id​ set?


PS

This is the complete backtrace of the error:

Hii,

Problem in Your Current Domain

This part:


[[ "value_ids" , "any" ,[value_id]],[ "attribute_id" , "=" , attribute_id]]

is incorrect because:

  • The any operator does not exist in Odoo's domain language.
  • Every condition in the domain must be a 3-element tuple/list : [field, operator, value]
Correct Way to Search for attribute_id and value_ids

To search for lines that have a specific attribute_id and one value in value_ids :

[
    [ "attribute_id" , "=" , attribute_id],
    [ "value_ids" , "in" , [value_id]],
]
  • "in" is the valid operator to check whether a value is in a many2many/one2many field.

Full Example

Here's how your XML-RPC call from Java/Python should look:

existing_line_ids = models.execute_kw(
    db, uid, password,
    'product.template.attribute.line' , 'search' ,
    [[
        [ 'attribute_id' , '=' , attribute_id],
        [ 'value_ids' , 'in' , [value_id]]
    ]]
)

This will return all product.template.attribute.line IDs that have:

  • The given attribute_id
  • At least one value_id equal to the one you're checking

i hope it is use fulll

Hi Bart:

There are 2 issues that need to be fixed in the domain - remove the extra [] on the outside and add a condition for product template (I'm assuming you have a variable called product_template_id in your code). Try changing the domain expression in your code to the following:

[["value_ids.id", "=", value_id], ["attribute_id", "=", attribute_id], ["product_tmpl_id", "=", product_template_id]]
